At once Medicine of East and West have the same purpose in treating, but there is a difference between the method of medical care and the view/slant on a disease each other. In the East Medicine, It is very difficult to explain the concept of Hwalhyulhwau but it is one of the way to cure cancer for long time. Be based on the theory of the East Medicine, research single medicine's anti-cancer effect among the natural products that has anti-cancer function. Moreover, for the purpose of finding new way to cure and prevent against cancer, we, the researchers, divided into four groups for this research: Group one: survey new substance with anti-cancer effects from natural products. Group two: research of anti-cancer mechanism through the experimental studies. Group three: research of immune responses in anti-canncer effects from natural products. Group four: research of the inhibitory effect on metastasis through the anti-angiogenesis. From the above results, we blended efficacious medidcines against cancer and made new prescriptions of Soam-I and Soam-II. Now, we are studying on these new prescriptions. We speculate that Soam-I and Soam-II may be used for a new conceptional anticancer therapy.

Senile involution is divided into two classes : physiological senile involution and pathological senile involution. Physiological senile involution is a natural process of vital action of decreasing Vital Essence and Energy in kidney that is a necessary physiological phenomenon. Pathological senile involution is an evidence of impairment of True Qi of internal human body. Human vital action is a changing process of life, senility, sickness, and death. In other words, this is a natural process of being full and decreasing of Vital Essence and Energy in kidney, and True Qi of human body decides this process. The Vital Essence and Energy in kidney vary, and they are influenced and restricted by various elements. The time of a senile involution varies individually. Human body protects and makes efforts not to leak out True Qi in effective ways. We can postpone a limit of time of physiological senile involution phenomenon. This is called 'Health Preservation' - resistance against senile involution.

In Jang-Sang theory, ‘Sang’ indicates ‘Hyung Sang’. The internal organs appear it's shapes(Hyung Sang) outward. ‘Hyung Sang’ is concept that was used on 「the book of changes」(周易) and 「Nei Ching」(內經) to means a thing's shapes and conditions. ‘Hyung’ is the shape, an organization composing a thing and ‘Sang’ is the symptom, an essence(a seed) immanenting a thing. To observe Hyung Sang, it have to apply the principle that ‘the sky and man correspond each other(天人相應)’. Usually ‘Hyung’ appears as shapes and ‘Sang’ appears as colors and conditions. Diagnosis on the basis of Hyung Sang put first the external expression of the five Jang six Bu organs and Jung-Ki-Shin-Hyul(精氣神血). So a doctor has to unite shapes, colors, pulse and symptoms(形, 色, 脈, 症) when diagnosis a patient. The theory of Hyung Sang includes the basic theories of the oriental medicine, the theory for Yin-Yang and the five element(陰陽五行論), organ picture(Jang-Sang), meridians(經絡學說), the five circuit phases and the six atmospheric influences(運氣學說), physical constitution(體質學說). I think that treatment based on Hyung Sang is shown the essence of the oriental medicine well. In the future, I think, we need to study more about the theory of Hyung Sang.

Phlegm is defined as the static fluid in excess in one or more parts of the body. It is not only a pathologic product but also a pathogen itself. However, as it says Phlegm is another title for the body fluid. phlegm can be physiological. In Hyungsang medicine. since the Hyungsang which an individual shows determines his or her illness. the principle to treat phlegm also varies according to the individual's Hyungsang. Thus, the author reviewed ‘Jisan’s Special Lectures for Clinicians’ and summarized the concepts and diagnostics of phlegm, and treatment and regimens by Hyungsang medicine. The concepts of phlegm : Phlegm is not only a pathologic product of disharmony of Jung(精), Ki(氣), Shin(神) and Hyul(血) but also a driving force to mature and transform these constituents. Phlegm is another designation for the Fluid. Phlegm can act as an alternative substance or buffering agent. If we describe our body as the habitat of worms. phlegm could be the inhabitant. Diagnostics of phlegm : The infraorbital areas have a dark-gray or blackish coloring. A man who is feminine or a woman who is masculine tends to develop phlegm. One of the major signs of phlegm is pain in Chungwan(中脘). The color of the skin does not change. Treatment of phlegm by Hyungsang medicine. For the Jung type(精科) and the Hyul type(血科), phlegm treatment is to supply Jung and Blood or eliminate Damp-phlegm. The man needs tonifying herbs and the woman needs herbs which promote the flow of Ki(氣). Children and the aged are. tegardless of the nature of disease, to be warmed and supplemented. For the heavy man. treatment is to supplement Ki and eliminate Damp; for the slim man. treatment is to supplement Yin(陰) and purge Heat.

In the present social-communicating situation of the folk remedies, we can say there is no responsible main group of it. When we look for recent published remedy books, their authors' background is too various. The folk remedy only focuses on the generality but it does not understand the problem of misusing with lack of explanation and classification in view of the oriental medicine. In conclusion, current folk remedies have formed a figure out of irresponsibility.

Galla Rhois is a gallnut of Rhus javanica Linne used for treatment of diarrhea, hemorrhage, cough, leukorrhea and toxic tumor etc in oriental medicine. For the evaluation of antitumor effect of Galla Rhois, activity based fractionation was done. We isolated an effective compound and identified 1,2,3,4,6-penta-O-galloyl-β-D-glucose(PGG) by photometric analysis such as NMR and MASS. Then, we studied the angiogenic activity of PGG. It showed a cytotoxicity against SK-OV-3, SK-OV-3, HT1080 with IC/sub 50/ of 50 ug/ml approximately. It also effectively inhibited proliferation of HUVEC cells treated by bFGF to 30% of control at 20 ug/ml and cell migration to 80% at 10 ug in a dose dependent fashion. Tube formation of HUVEC cells on matrigel was effectively suppressed from 2.5 ug/ml of concentration by PGG. Moreover, it effectively recovered the dysfunction of gap junctional intercellular communication in WB-F344 rat liver epithelial cells caused by hydrogen peroxide at 4 ug/ml suggesting it potently can inhibit tumor promotion. Taken together, it indicates 1,2,3,4,6-penta-O-galloyl- β -D-glucose has antiangiogenic activity.

This present study was designed to screen medicinal plants for the treatment of brain diseases such as Parkinson's disease or Alzheimer's disease. The inhibitory activity of monoamine oxidase B (MAO-B) was investigated in the water extracts of 56 species traditional medicines. Among the tested medicinal plants, E. lathyris, R. palmatum, F. rhynchonphylla, E. caryophyllata, E. pekinensis and H. syriacus were showed the strong inhibitory activity against MAO-B. Therefore, MAO-B inhibitory activity of 6 traditional medicine extracts in the different concentration (2.5, 6.5 and 12.5 ㎍/ml) was determined. The inhibitory effect of MAO-B was detected with dose dependently in 6 traditional plants extracts. E. caryophyllata and R. palmatum were showed the highest inhibitory activity, the MAO-B inhibitory activity at 2.5㎍ of herbal extract being 58% and 52%, respectively. The water extracts of 6 species were tested on antioxidant activity using radical scavenging effects against ABTS/sup +/. The water extracts of R. palmatum, E. caryphyllata, E. pekinensis and H. syriacus were showed strong antioxidant capacity at 20 ㎍ concentration. Among the 56 medicinal plants investigated, the water extracts of R. palmatum and E. caryphyllata were showed significant antioxidant capacity and MAO-B inhibiory activity. Therefore, R. palmatum and E. caryphyllata are expected to ameliorate the clinical symptoms in Parkinson's disease due to significant MAO-B inhibition and radical scavenging effect.

Author applied several engineering methodologies to classical ultrasonic nebulizer to cope with it's demerits. After several trials and errors, we got the several meaningful results. To evaluate the modified ultrasonic nebulizer for inhalation toxicology of cadmium, author used light-scattering photometer. This paper is the one part of inhalation exposure systems for inhalation toxicology study of cadmium. According to the testing conditions, source temperature 50℃ and inlet-duct band temperature 150℃, aerosol generation results for sodium chloride and cadmium chloride were as followings: Coefficients of variation(CV) of sodium chloride and cadmium chloride for repeated trials were 3.38 and 4.77 for 10g, 2.47 and 5.02 for 5g, and 4.70 and 2.98 for 2.5g. All the CVs were within 10% of acceptance variability. Count Per Minute(CPM) changes of NaCl and CdCl₂ for 5 repeated trials were similar. CPM ratios of CdCl₂/NaCl were 1.13 for 10g, 0.76 for 5g, and 1.06 for 2.5g. Relative aerosol generation of cadmium chloride to sodium chloride was the highest in 10g. Efficiency increases of 24.50% for 5g NaCl, 14.91 % for 2.5g NaCl, and 16.48% for 2.5g CdCl₂ with respect to theoretical efficiency were observed but 0.04% efficiency decrease was observed in 5g CdC₂. According to the modifications of source temperature(20, 50, 70℃) and inlet-duct band temperature(20, 50, 100, 150, 200℃), aerosol generation results for NaCl and CdCl₂ were as followings: CPM trends for each quantity excepting 10g NaCl in inlet-duct band temperature 200℃ were similar, and the highest CPM was observed in source temperature 70℃ to each inlet-duct band temperature. The highest CPMs to 10, 5, and 2.5g NaCl were observed in source temperature 70℃ and inlet-duct band temperature 20℃. Aerosol generation of cadmium chloride was increased with the higher source temperature, excepting inlet-duct band temperature 200℃. The highest CPMs for 10, 5, and 2.5g CdCl₂ were observed in source temperature 70℃ and inlet-duct band temperature 20℃, and this trend was similar to NaCl aerosol generation The highest CPMs for 10, 5, and 2.5g CdCl₂ were observed in source temperature 70℃ and inlet-duct band temperature 20℃, and this result was similar to NaCl aerosol generation. Observed efficiencies of 5 and 2.5g NaCl were similar to ifs theoretical efficiency but -3.08% efficiency decrease of 5g CdCl₂, 17.47% efficiency increase of 2.5g CdCl₂ were observed. CPM ratio of CdCl₂/NaCl of 10g was different to 5 and 2.5g, and 2.5g ratio was higher than 5g ratio. In conclusion, to get maximum aerosol generation for NaCl and CdCl₂ will be the conditions that set the appropriate inlet-duct band temperature for each materials and increase the source temperature. Sodium chloride can be used to evaluate the performance and predict the concentration for cadmium aerosol in aerosol generator and inhalation exposure system.

The purpose of this study was to investigate the effect of Kamigedang-tang(KGDT) water extract on the antitumor and anti metastatic activity. The results were summarized as follows: KGDT extracts exhibited a significant cytotoxicity against P388, SK-MEL-2, SK-OV-3, and B16-F10 cell lines and showed significant inhibitoty effect on DNA topoisomerase I from calf thymus. The T/C% was 122.9% in KGDT treated group in S-180 bearing ICR mice. Also, KGDT extracts exhibited efficient affect adhesive effect of A549 cell to complex extracellular matrix. In CAM assay, KGDT extracts inhibited angiogenesis at 15㎍/egg concentration insignificantly as compared with control. These results suggested that KGDT extracts might be usefully applied for prevention and treatement of cancer.

Jookrhyuk (Bambusae Caulis in Liqamen) is one of the most important ingredients for treating Diabetes mellitus. Various aspects of quality of Jookrhyuk produced in Korea depending on carbonization process were compared. The pH Value was the highest in Jinyoungsangsa Jookrhyuk(pH 3.17) among the three different Jookrhyuk samples. Damyangsan Jookrhyuk that contains high level of total sugars(8.0 Brix, %) show incresed level of tar contents, it exhibited positive realationship between total sugar and tar contents. Concentration of methanol and phenolic compounds which are related to toxicity were the highest in Damyangsan Jookrhyuk(1.34㎎/㎖, 3.84㎎/㎖ respectively). The harmful heavy elements were not found in the evaluated Jookrhyuk samples. In coclusion, it was suggested that Bambusae Caulis in Liqamen should be further puryfied for using as main oral medicines for treating Diabetes mellitus.

APA-01, which is an aqueous extract of five Chinese herbs, is a modified formula of Huoxiang-Zhengqi-San. The effect of new herb extract on immune response was investigated. The parameter examined to assess apparent immune response of APA-01 in mice included changes of body weight, relative weight of immune organs, cell proliferation and cytokine gene expression. The body weight and relative weight of immune organs were not significantly changed among the tested groups. In the spleen cell prolijeration assay, APA-01 increased the cell proliferation in a dose-dependent manner. Methotrexate (MTX), an agent of immune suppression, inhibited the spleen cell proliferation (IC/sub 50/: 800㎍/㎖). However, APA-01 significantly inhibited the suppression of mouse spleen cell proliferation. Therefore, it seems that APA-01 has a reducing effect of immune suppression. Immunomodulatory effect of APA-01 was further investigated using reverse transcription polymerase chain reaction (RT-PCR) in mouse spleen cells. In RT-PCR test, APA-01 enhanced the expression of cyclooxygenase-2 (COX-2) mRNA in a dose-dependent manner. In spite of immune suppression by MTX, COX-2 mRNA was induced by co-treatment with APA-01. These results suggest that APA-01 stimulates the proliferation of spleen cells, regulates the expression of COX-2 mRNA, and accelerates the recovery of inhibition of spleen cell proliferation induced by MTX, thus providing the immunological basis for clinical benefit of APA-01.

The purpose of this study is to investigate the effect of Shudihuang water extracts on the cGMP production of medulla and cortical membranes, receptors for atrial natriuretic peptide in the kidney by in vitro autoradiography in rats for 8, 16 weeks. The cGMP production of medullary and cortical membranes of the kidney decreased after the administration of Shudihuang water extracts. The density of receptors for atrial natriuretic peptide in the kidney decreased after the administration of Shudihuang water extracts only for 16 weeks. These results suggest that the long term administration of Shudihuang water extracts has decreased plasma renin activity and plasma levels of aldosterone modulated cGMP production of medullary and cortical membranes, density of receptors for atrial natriuretic peptide in the kidney.

Cytotoxicity of glucose oxidase(GO) and neuroprotective effect of Aconiti Radix(AKR) against GO-induced neurotoxicity were measured for elucidating the mechanism of cardiotoxicity on cultured mouse myocardial cells by MTT assay after myocardial cells were cultured for 24 hours at various concentrations of GO. GO was toxic in a time-and dose-dependent manner on cultured myocardial cells after myocardial cells were grown for 24 hours in media containing 5～40mU/ml GO. While, cultures were pretreated with 50 μg/ml AKR for 2 hours increased remarkably cell viability. From the above results, it is suggested that GO is toxic on cultured mouse myocardial cells by the decrease of cell viability, and herb medicine such as AKR is very effective in the prevention of myocardial toxicity induced by GO.

Two of the essential processes required for metastasis are neoangiogenesis and tumor cell invasion of basement membranes (BM) and extracellular matrix (ECM). Recently, data showed that herbs removing blood stasis has an anti-angiogenic effects. Tonifying vital Qi and eliminating pathogenic factor was a basic modality in Oriental oncology. In this study, we investigated several Qi and Blood tonics for potent angiogenic inhibitors. Methanol extracts of samples inhibited the proliferation of ECV-304 at the concentration of 100 ㎍/㎖. Zizyphi Fructus, Glycyrrhizae Radix, Angelicae Gigantis Radix decreased the gelatinolytic activity of MMP-9 from ECV-3Q4, at the concentration of 100 ㎍/㎖ in gelatin zymography. In in vitro invasion assay, herbs inhibited the invasion activity of ECV-304 by 53% of control (Ginseng Radix), 39% (Zizyphi Fructus), 36% (Angelicae Gigantis Radix), 25% (Glycyrrhizae Radix). Ginseng Radix inhibited the capillary-like tube formation of ECV-304 at the concentration of 160 ㎍/㎖, Angelicae Gigantis Radix and Paeoniae Radix Alba inhibited at the concentration of 320 ㎍/㎖. These results indicated that Ginseng Radix, Glycyrrhizae Radix, and Angelicae Gigantis Radix could be considered as potent angiogenic inhibitiors.

Jaeumgenby-tang(JGT) have been used in oriental medicine for many centries as a a therapeutic agent of vertigo caused by deficiency of qi and blood. The effects of JGT on the regional cerebral blood flow(rCBF), mean arterial blood pressure(MABP) and cardiac muscle contractile force(CMF) is not known. The purpose of this Study was to investigate effects of JGT on the rCBF, MABP, CMF and mechanism of JGT induced changed rCBF, MABP, CMF. The changes of rCBF, MABP and CMF were determinated by Laser-Doppler Flowmetry(LDF). The results were as follows; JGT extract was increased rCBF, MABP and CMF in a dose-dependent, specially JGT extract was significantly increased rCBF and MABP. Pretreatment with propranolol was significantly inhibited JGT induced increase of rCBF but pretreatment with indomethacin and methylene blue were accelerated JGT induced increase of rCBF. Pretreatment with propranolol and indomethacin were inhibited JGT induced increase of MABP, but pretreatment with methylene blue was accelerated JGT induced increase of MABP. Pretreatment with propranolol was significantly inhibited JGT induced increase of CMF but pretreatment with indomethacin and methylene blue were accelerated JGT induced increase of CMF. This results suggest that JGT increased rCBF by increasing MABP and CMF and the action of JGT is mediated by adrenergic β-receptor.

Paljinhangahm-dan is an Oriental herbal formulation for its ability to modulate cancer cell growth and survival. This research was performed to study the anti-cancer effects of Paljinhangahm-dan water extract(PHWE) in human pro myelocytic leukemia(HL-60) cells. After HL-60 cells were routinely cultured, tetrazolium-based colorimetric(MTT) assay was performed for cytotoxicity test. To explore the mechanism of cytotoxicity. I used several measures of apoptosis to determine whether this processes was involved in PHWE-induced cell death in HL-60 cells. In addition, the experiment was practised 1 H-NMR spectroscopy to examine molecular structure of PHWE. This study suggested that PHWE control cancer cell growth through of apoptosis with less cytotoxicity in normal cells.

The Caesalpinia sappan is widely used in the traditional oriental herbal medicine for anti-inflammatory, antioxidant effects. The effects of water extract of C. sappan on the cell viability and induction of apoptosis were investigated in human lung cancer cell line A549. The water extract of C. sappan produced apoptotic cell death and DNA fragmentation and nucleus chromatin condensation in A549 cells. The enzyme activity of caspase-3 and protein level of actived caspase-3 were markedly increased in A549 cells treated with the water extract of C. sappan. In addition, the extract of C. sappan induced cleavage of Poly (ADP-ribose) polymerase (PARP), a known substrate for caspase-3, and dropped in cellular ATP levels. These results suggest that the extract of C. sappan exerts anticancer activity by induction of apoptosis via activation of caspase-3, cleavage of PARP protein, and depletion of cellular ATP levels in A549 cells.

In Traditional Oriental Medicine, there has been a growing needs for computerized diagnosis expert system, which can implement pre-diagnosis and correct the errors of practitioners. Therefore, we developed the expert system (KHU-PIPE : Kyung Hee University - Pattern Identification and Prescription Expert) for diagnosis and treatment. It has three characteristics as following. First. this system has the knowledge base which modified the standardized data designed by Chinese government during 1980s. Second, it provides the objective and standardized diagnosis as the results of pattern identification and their appropriate prescriptions for treatment. Third, it is applied to both LAN system and internet. Furthermore, it can be used as an educational methods for the practices of pattern identification and prescription, and provide the objective criteria for clinical studies and promote the Traditional Oriental Medicine as an evidence-based medicine.

Jookrhyuk (Bambusae Caulis in Liqamen) was extracted at low temperature (100℃ - 160℃) and purified by adsorption and distillation and their physicochemical properties were compared. In case of colour among all Jookrhyuk samples the L value appeared to be higher in the purified Jookrhyuk,and the b value appeared to be higher in crude Jookrhyuk. Purified Jookrhyuk showed much lower level of total sugar and tar contents than crude Jookrhyuk. A considerable reduction in concentration of methanol and phenolic compounds was achieved by purification process, whereas the content of acetic acid was increased. Therefore it was suggested that adsoption and distillation could be used as one of effective purification methods of various Joockrhyuk samples.

When a Kigong master concentrates the Qi at Yintang, Laogong(P8), Qihai(CV6) meridian points during Kigong state, the change of magnetic field around acupoints Yintang, Laogong points has been measured using DROS-SQUID apparatus. After smoothing process of the continuously measured magnetic signal around acupoints for a few minutes, we could observe that a series of peaks, magnitude of 1～2 pT and period of 5 sec, appeared and find that these peaks were clearly changed as if switch on and off according to Qi concentration state. Before Qi radiation, a series of the peaks measured on Yintang or Laogong point of a Kigong master shows one of either SW-ON state or SW-OFF state as initial state. During Qi radiation, its state becomes inverse of initial state. After Qi radiation, it returns to the initial state for some cases (called P type ; push button switch type) or it remains inversion state for other cases (called T type; toggle switch type). From the data of peaks measured at different position from the Qi concentration acupoint, we found that the Qi radiation on an acupoint makes the switching effect even not at the acupoint that Qi is concentrated but at the other acupoints that Qi is not concentrated.

The purpose of this study was to investigate the effect of 2-thioDMNQ-S160, shikonin analogue isolated from Uthospermum Erythrorhizon, on the antitumor activity. In the present study, 2-thioDMNQ-S160 exhibited a significant cytotoxicity against L1210, A549, U937, and 816-BL6 cell lines with IC/sub 50/s of 2.4ug/ml, 2,0ugjml. 4ug/ml and 20 ug/ml, respectively. 2-ThioDMNQ-S160 strongly inhibited adhesion of B16-BL6 cells to gelatin and matrigel coated matrices. Also, 2-ThioDMNQ-S160 exhibited anti-invasive effect of B16-BL6 cells. The T/C% was 123 % in 2-ThioDMNQ-S160 treated group in S-180 bearing ICA mice. These results suggested that 2-thioDMNQ-S160 might be a potent candidate of cancer drug.

To investigate an efficacy of mixed extract with Ginseng radix, Puerariae lobata, Puerariae radix, Rubi pructus, Gomi pructus, Hoelen, Dried orange peel and Parvum comus cervi etc., on the hangover elimination, 12 hr-fasted male Sprague-Dawley rats weighing 150-200 g were given mixed extract (5 mL/kg, p.o.) and administered ethanol at a dose of 3 g/kg bw (25% in distilled water) orally 30 min postdosing. Blood was collected from caudal artery at 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12hr and then the animals were sacrificed at 24hr after the ethanol treatment. In these experiments, liver function indices, such as alanine aminotransferase and alkaline phosphatase activities, showed unaltered results in all treated groups compared with the normal group. The pharmacokinetics of ethanol after oral administration of mixed extract were also evaluated. From 0 min to 12hr, the administration of mixed extract showed 14% reduction of the area under the serum concentrations-versus-time curves (AUC) compared with the control group. The activities of alcohol dehydrogenase and aldehyde dehydrogenase measured at 24hr postdosing were also not altered by the administration of mixed extract compared with the control group. These studies demonstrate that oral administration of mixed extract, prepared by traditional prescription, decreases the ethanol concentration in serum and reduces AUC, suggesting that the mixed extract is effective for elimination of ethanol-induced hangover.

To study the effects of Scorpio on oxygen free radical-mediated damage by xanthine oxidase/hypoxanthine (XO/HX) on cultured spinal sensory neurons, in vitro assays such as MTT assay were used in cultured spinal sensory neurons derived from mice. Spinal sensory neurons were cultured in media containing various concentrations of XO/HX for 6 hours, after which the neurotoxic effect of XO/HX was measured by in vitro assay. The protective effect of the herb extract, Scorpio water extract against XO/HX-induced neurotoxicity was also examined. The results are as follows : In MTT assay, XO/HX significantly decreased the cell viability of cultured mouse spinal sensory neurons according to exposure concentration and time in these cultures. The effect of Scorpio water extract on XO/HX-induced neurotoxicity showed a quantitative increase in neurdfilament. These results suggest that XO/HX has a neurotoxic effect on cultured spinal sensory neurons from mice and that the herb extract, Scorpio water extract, was very effective in protecting XO/HX-induced neurotoxicity.

The present study was made with the aim of finding out the Kamihaepyoijin-tang's effect on the allergic asthma using the Egg-White Implant(EWI) method model recommended by de Siqueira et al. Kamihaepyoijin-tang has widely been prescribed and used in Oriental Medicine for controlling and curing of cough, asthma, nasal obstruction. Previous studies have demonstrated that Kamihaepyoijin-tang had analgesic, anticonvulsive effects. But it is uncertain whether Kamihaepyoijin-tang could inhibit the allergic reaction of rats with experimentally induced allergic asthma using EWI method. With such aim. the respiratory patterns and eosinophil infiltration in the tracheal mucosa of the rats were mainly observed. The results were summerized as follows ; 1. The frequency of malformed respiratory patterns in Kamihaepyoijin-tang treated groups were decreased as compared with the control group. 2. The Ratio of malformed respiratory patterns in Kamihaepyoijin-tang treated groups were significantly decreased as compared with the control group(p<0.02). 3. The eosinophil infiltration in Kamihaepyoijin-tang treated groups were decreased as compared with the control group. 4. The eosinophil infiltration that inside of trachea tissue in Kamihaepyoijin-tang treated groups were significantly decreased as compared with the control group(p<0.05). Depending upon above results, it is considered that Kamihaepyoijin-tang has the inhibitory effects on the allergic asthma of rats and suggested that it could be used in relieving patients of the symptoms which are caused by allergic asthma.

To evaluate the effect of Jingansikpung-tang(JST) water extract on cultured mouse spinal sensory neuron which was inhibited by glucose oxidase(GO)-induced cytotoxicity, MTT and LDH activity assay were carried out after the cultured mouse spinal sensory neuron were pre-incubated with various concentrations of JST extract for 3 hours prior to exposure of GO. The results obtained were as follows: GO, a oxygen radical, decreased the survival rate of the cultured mouse spinal sensory neuron cells on MTT assay. JST water extract have efficacy of decreasing LDH activity increasing by GO in cultured mouse spinal sensory neuron. From above the results, it is concluded that JST water extract has marked efficacy as a treatment for the damages caused in the GO-mediated oxidative process.

In order to prove the sedative, anticonvulsive effects of Incenses and to identify the effect of this medicine to cerebral glutamic acid and GABA density in experimental animal. we used Incense which was made of traditional herb medicines. We also examined what kind of material is to be involved in biosynthesis of these elements. In addition we experimented to find out synthesis of active GABA-T. Incenses were inhaled 8 hours a day for 4 weeks to mice. Finally we have following results. On the convulsion induced by pentylenetetrazole(PTZ), Incenses showed significant anticonvulsive effect. Density of glutamic acid in brain was significantly decreased. On the contrary, density of GABA was significantly increased. The Activity of GABA- T in brain was significantly reduced. The quantity of lipid peroxide in the brain was significantly decreased. Activity of xanthine oxidase and aldehyde oxidase were significantly reduced in brain. From the above results, we confirmed that Incenses decreased the density of glutamic acid, increased GABA density and decreased the activity of GABA- T in brain. For the convulsion which was induced by PTZ, Incenses showed significant anticonvulsive effect. With this we can recognize that Incenses had ability to control the quantity of lipid peroxide in brain. In the conclusion, Incenses has significant anticonvulsive effect, so I strongly recommend to prescribe Incenses to treat convulsive disorder like epilepsy.

Banhasasim-tang(半夏瀉心湯), oriental medicine, has been used for the treatment of the gastric diseases and cimetidine, H2-receptor blocker, has been also used as the gastric ulcer remedy but has some side action. Therefore the concurrent administration of these two drugs may increase antiulcer activities and also decrease cimetidine's side action more than administrating one by one. In order to investigate antiulcer activities, some experiments were conducted. The concurrent administration of Banhasasim-tang extract(BS) and cimetidine(CM) given intraperitoneally (CM 50mg/kg + BS 300mg/kg and CM 50mg/kg + BS 500 mg/kg), significantly inhibited Shay, aspirin and indomethacin ulcers in rats.

It has been suggested that oxidative stress may play an important role in the pathogenesis of diabetic complications. The purpose of this study was to examine the oxidative stress of streptozotocin(STZ) in the cultured mouse cerebral neurons and the preventing effect of vitamin E and and Benincasae Semen(BS) on STZ-induced neurotoxicity. Cytotoxic effect of STZ and neuroprotective effect of antioxidant and BS were performed by MTT assay. 30 μM STZ decreased cell viability in dose-and time-dependent mannner, and vitamin E and BS diminished STZ-induced neurotoxicity in these cultures. From above the results, STZ has toxic effect. and antioxidants, vitamin E or herb extract of BS is very effective against STZ-induced neurotoxicity in cultured cerebral neurons of neonatal mouse.

Paraquat, one of the potent herbicides, causes fatal damage to many vital organs, when orally ingested, resulting in circulatory failure, respiratory distress syndrome, and a few other serious problems, but there is no known specific antidote against it. Of the possible problems related to paraquat intoxication, oliguric acute renal failure, which has been known to develop within 24 or 48 hours after intoxication, are notoriously life-threatening. So we attempted to investigate the clinical characteristics and progress of paraquat-induced acute renal failure and the therapeutic possibilities of herbal medicines. All of the fifteen subjects were treated with intravenous fluid injection of 5% dextrose saline or 10% dextrose water in conjunction with herbal medicines which were used for oral administration or gargling. Gamdutang, a decoction of Semen Glycin(黑豆 200g) and Radix Glycyrrhizae(甘草 100g) with addition of other herbs when necessary, was administered orally. At the same time, gargling fluid, consisted of Chinese ink(墨汁), char-frying powder of Rhei Rhizoma(大黃炒炭末), Succus phyllostachyos(竹瀝), was used to detoxify the oral cavity. Serum levels of Blood Urea Nitrogen(BUN) and Creatinine reached its peak on the third day of hospitalization, but then decreased and fell within the normal range on the 7th day and remained there. Serum levels of Na+ and K+ decreased down below the lower limits of normal range on the 7th day and on the 3rd day, respectively. Then they returned back within normal limits. Mean urine output on the 1st day of hospitalization was 1,050ml and it continuously increased to reach more than 2,000ml on the 14th day. From that day on, it stayed over 2,000ml. Fifteen cases of acute renal failure caused by paraquat intoxication were treated with combined treatments of oriental and western medicine in our hospital. However, we think that it is necessary to study further about the way to combine oriental and western medicine, to find out a more effective treatment method.

The current study was carried out to evaluate neuroprotective effects of Citri Pericarpium after transient global ischemia in gerbils. Male Mongolian gerbils weighing 60-80g were anesthetized with 2% isoflurane mixed with 30% oxygen and 70 % nitrogen. Bilateral common carotid arteries were occluded for 5 minute with microaneurysm dips. On 3 or 7 days after ischemic surgery, the gerbils were sacrificed. The brain were removed, embedded in paraffin and sectioned at 8㎛-thickness. Gerbils that received ischemic insult for 5 min showed extensive neuronal damage in the hippocampal CA1 region, and the number of viable neuronal cell was 51.0±2.5/mm, 32.2% of normal group at 7 days after ischemic surgery. In animals that underwent the extract of Citri Pericarpium treatment, the number of viable neuronal cell were significantly better preserved at 110.58±3.58/mm, 72.0% of normal group than those of ischemic group (P<0.01). In the immunohistochemistry of Bax and Bcl-2, the Citri Pericarpium treated group down-regulated the expression of Bax protein at 72hr after transient global ischemia. In contrast, Bcl-2 protein level was not changed. The appearance in TUNEL assay is similar to the pattern of Bax protein. The water extract of Citri Pericarpium significantly reduced the number of TUNEL-positive CA1 pyramidal neurons at 72hr. The results suggest that Citri Pericarpium has potential neuroprotective effects in the transient global ischemia and the increase in the ratio of Bcl-2 to Bax may contribute to the anti-apoptotic effect of Citri Pericarpium.

To investigate whether Puerariae radix (PR) possesses protective effect against ethanol (EtOH)-inducecl apoptosis in the central nervous system, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay, flow cytometric analysis, DNA fragmentation assay. and reverse transcription-polymerase chain reaction (RT-PCR) were performed on human neuroblastoma cell line SK-N-MC. Morphological and biochemical analyses demonstrated that SK-N-MC cells treated with EtOH exhibit classical apoptotic features. On the other hand, cells pre-treated with PR prior to EtOH exposure showed decreased occurrence of classical apoptotic features. In addition, it was shown that PR pre-treatment inhibits EtOH-induced increases in the levels of mRNA expression of bax and caspase-3, while it further enhances the level of bcl-2 expression. These results suggest that PR may exert protective effects against EtOH-induced apoptosis in human neuroblastoma cells.

A medical treatment of alternating current high-voltage electric field therapy is a method in which we get a healing effect, applying electric field to an organism through an artificial device. In order to estimate the clinical effects of alternating current high-voltage electric field load(HEALTHTRON) on the rehabilitation of stroke patients, improvement of a peripheral blood circulation, and psychogenic symptom, we used BEUNZEUNGHEYNG Instrument, NIHSS(the National Institutes of Health Stroke Scale), FIM(Functional Independence Measure)lnstrument to research BEUNZEUNGHEYNG and recovery of rehabilitative funation. and also we used Thermography, Pulse Meter to measure body temperature and pulse, blood elements, and neuro modulators. We have reached the following conclusions after researching the clinical effects of alternating current high-voltage electric field therapy on the recovery of rehabilitative function and peripheral blood circulation. 1. HEALTHTRON efficiently has increased the volume of peripheral blood circulation in stroke patients. 2. HEALTHTRON rapidly has treated the symptoms of sleeplessness, alertness, and dizziness of stroke patients. 3. HEALTHTRON rapidly has improved rehabilitative function of stroke patients and the adjustment to their activities.
