본 연구는 BALB/c 마우스에서 감마선 조사 후 루틴을 7일 동안 경구투여하여 감마선 조사로 인한 조혈계 및 간세포 손상에 대한 방사선 회복 효과를 검토하였다. 루틴의 투여는 감마선 조사군에 비해 조혈 면역계 손상을 억제하여 보호하였으며, 증가된 간독성 지표 효소도 유의적으로 감소하여 간세포 손상에 대한 보호효과를 확인하였다. 방사선 조사에 의해 체내에서 생성된 자유 라디칼은 생체물질과 결합하여 지질과산화를 일으키고 산화적 스트레스를 유도하여 조직을 손상시킨다. 루틴을 투여한 군은 감마선 조사군에 비해 지질과산화가 유의적으로 낮게 나타나 방사선에 의한 장해를 감소시킨 것으로 사료된다. 루틴을 투여한 군의 항산화 효소의 활성은 감마선 조사군에 비해 유의적으로 증가하여 생체 내에 항산화 활성을 회복시켰다. 이 상의 결과를 통해 방사선 조사 후에 루틴의 투여는 방사선에 의한 조혈계 및 간세포 손상에 대해 회복 효과가 있어 방사선 보호제로 유용하게 사용될 수 있다.

혈액세포의 분화와 성장은 20 여종 이상의 성장인자에 의해 조절된다. 혈액세포 생산에 관여하는 인자를 조혈 성장인자(hematopoitic growth factor)라고 한다. 조혈성장인자를 임상적으로 사용하기 위해 원핵생물 또는 진핵 생물 생산 시스템에서 재조합 단백질로 생산되고 있다. 그 중에서 Glranulocyte-Colony Stimulating Factor(G-CSF)는 호중구 세포 수가 감소된 암환자와 선천성 질병을 가진 환자에게 임상적 치료제로 아주 중요한 역할을 한다. 이 환자들은 충분하지 못한 호중구 세포로 말미암아 감염에 대한 위험이 아주 높으며 치사율 또한 높다. 두 종류의 재조합 G-CSF가 항암치료 후 발생하는 부작용으로 나타나는 호중구 세포 감소증 치료에 사용되고 있다. G-CSF의 중요성에 맞추어 G-CSF의 물리적 및 생물학적 기능에 대한 특성을 설명하였으며, 또한 항암치료와 G-CSF의 임상적 사용에 대한 연관성을 토론하였다. 마지막으로 두 종류의 재조합 G-CSF인 non-glycosylated G-CSF, filgrastim과 glycosylated G-CSF를 비교 설명하였으며, 이들 기존의 G-CSF에 비교되는 바이오시밀러에 대한 전망을 제시하였다.

In the Encyclopedia Medica Koreana(Dongeuibogam), I have researched 245 prescriptions in which Panax Ginseng plays an important role. And I have got the following results. The healing scope and frequency of ginseng-mainly-included prescriptions are Child Part 29(11.83%), Violent Cough Part 23(9.38%), Sick-by-Cold Part 21(8.57%), Oncosis Part 16(6.53%), Overwork Part 14(5.71%), Gynecologic Part 14(5.71%), Internal Part 13(5.3%), Apoplexy Part 11(4.48%), Mind Part 10(4.08%) and Fecal Part 10(4.08%) prescriptions. And also each of Nausea Part, Anger Part, and Spirit parts has the same 5 (2.04%) prescriptions. And each of Qi Part, Diabetes Meatus Part, Malaria Part, and Humoral Part has 4(1.63%) prescriptions. And each of Foot Part, Choleraic Part, Genital Part, Blood Part, and Voice Part has 3 (1.2%). All of these prescriptions cover 88.88%. And besides listed parts above, Panax Ginseng is all used in 48 Parts: Body-Mind Part. Mouth-Tongue Part, Breast Part, Muscle Part, Swelling Part, Urine Part, Epidermis Part, Heat Part, Anus Part, Stomach Part, Eye Part, Laryngopharynx Part. Uterus Part" Heavy Stomach Part, Head Part, Pulse Part, Hair Part, Navel Part, Emetic Part, Costal Part, Edema Part, Vomiting Part, Superstitious Part, and Cardiac Part, etc. Of the prescriptions in which Panax Ginseng plays an important role, the most representative diseases, which more than 86.8% prescriptions cure, are shock, numbness from cold, Taeeum disease, oncosis, overwork, sick from eating, numbness of extremities, diarrhea, tachycardia, forgetfulness, nausea, heat from kidney, nocturnal emission, short breath, diabetes meatus, malaria, sweating, sweating overnight, beriberi, cholera, insomnia from enervation, sialitis, navel pain, hemorrhage, and loss of voice. The pathology of the prescriptions in which Panax Ginseng plays an important role is divided into the organ problems, six natural factors, seven extreme feelings, unbalanced humoral status, overwork, and, unbalance of qi and blood. Spleen, heart, and uterus is the main cause of organ problems; wind and cold are the main cause of six natural factors; heavy humors are the main cause of unbalanced humoral status; the stasis of seven feelings are the main cause of seven extreme feelings; the lack of stamina and overwork are the main cause of the overwork; the lack of qi, the lack of blood, and, the lack of qi and blood are the main cause of the unbalance of qi and blood. After I have researched the contents of the prescriptions in which Panax Ginseng plays an important role, I could understand the addition of the different prescriptions, combination of medicines, and the role of medicine groups associated with Panax Ginseng. So from now on, the results I have got could be used as the data which show the theoretical basis on the prescriptions.

Objectives : This study was designed to determine the effects of the GGEx18 ethyl acetate fraction(EF) on body weight gain, feeding efficiency ratio, and obesity-related factors in plasma as well as histology of liver and adipose tissues using high fat diet-fed male C57BL/6N obese mice. Methods : 8 weeks old, high fat diet-fed obese male mice were divided into 5 groups: C57BL/6N normal, control, EF(1), EF(2) and EF(3). After mice were treated with EF for 9 weeks, we measured body weight gain, food intake, feeding efficiency ratio, fat weight, plasma leptin and lipid levels. We also analysed histology of liver and adipose tissues on high fat diet-fed male C57BL/6N obese mice. Results : Compared with control, EF-treated mice had significantly lower body weight gain and feeding efficiency ratio. Consistent with the effects on body weight gain, EF significantly decreased the adipose tissue weight compared with control. Consistent with the effects on feeding efficiency ratio, EF significantly decreased plasma leptin concentrations compared with control. EF reduced the size of adipocytes as well as hepatic lipid accumulation compared with control. EF seems to be safe since not only the plasma levels of ALT and AST are within the normal range, but also EF did not show any toxic effects on organs. EF(3) was most effective among EF(1), EF(2), and EF(3) at doses of 25, 50, and 100 mg/kg, respectively. Conclusions : These results demonstrate that EF effectively reduces body weight gain, feeding efficiency ratio in high fat diet-fed obese mice, leading to the modulation of obesity. In addition, EF decreases the size of adipocytes and improves plasma lipids and controls hepatic lipid accumulation, suggesting that EF may act as a therapeutic agent for obesity.

To evaluate the possible therapeutic effects of growth hormone and vitamin C on multiorgan failure, a rat model was developed for LPS-induced sepsis. Using this model, the effects of growth hormone and vitamin C on tissue damages, catalase and i-NOS activities, and MDA levels were examined in the lung and liver. The level of TNF- in plasm was also examined. Male, Sprague-Dawley rats were injected with LPS intraperitoneally then divided into 3 groups : positive controls injected with LPS only, the ones injected with growth hormone or vitamin C immediately after the LPS injections. The lung and the liver were then isolated, blood samples were collected at 24 or 48 hours after the LPS injection, then examined for histopathological and biochemical changes. The results obtained were as follows. 1. LPS induced sinusoid vasodilation and mild destruction of lobular structure in the liver. In the lung, alveolar structure appeared to be thickened and interstitial edema was observed. The levels of MDA in the liver and the lung was increased by LPS, while the activity of catalase was decreased. The activity of i-NOS of those tissues was also increased, which was more pronounced at 24 hr. The level of TNF- in plasm was increased by LPS 2. In the lung, vitamin C suppressed lymphocyte and neutrophil infiltration, alveolar wall thickening and interstitial edema. In the liver, vitamin C protected against the destruction of the lobular structure. The activity of catalase reduced by LPS was reversed partly by vitamin C. The activity of i-NOS enhanced by LPS was also reversed by vitamin C. The level of TNF- in plasm reduced in some animals by vitamin C, which however was not significant statistically(p<0.05). 3. Growth hormone showed similar protective effects against inflammation and damages in the liver and lung tissues. Growth hormone reversed partly the LPS effects on the level of MDA, the activity of catalase and i-NOS induction in the liver and the lung. Growth hormone reduced plasma level of TNF-${\alpha}$ substantially, which contrasted from vitamin C. Besides this, overall protective effects of growth hormone against LPS-induced experimental sepsis were similar to those of vitamin C. From this results, the mechanism of growth hormone on suppression of LPS-induced tissue damage might be associated with production of antioxidative enzyme and suppression of plasma TNF- level.

Objectives: Although nerve growth factor (NGF) could promote the functional regeneration of an injured peripheral nerve, it is very difficult for NGF to sustain the therapeutic dose in the defect due to its short half-life. In this study, we loaded the NGF-bound heparin-conjugated fibrin (HCF) gel in the NGF-delivering implants and analyzed the time-dependent release of NGF and its bioactivity to evaluate the clinical effectiveness. Materials and Methods: NGF solution was made of 1.0 mg of NGF and 1.0 mL of phosphate buffered saline (PBS). Experimental group A consisted of three implants, in which $0.25{\mu}L$ of NGF solution, $0.75{\mu}L$ of HCF, $1.0{\mu}L$ of fibrinogen and $2.0{\mu}L$ of thrombin was injected via apex hole with micropipette and gelated, were put into the centrifuge tube. Three implants of experimental group B were prepared with the mixture of $0.5{\mu}L$ of NGF solution, $0.5{\mu}L$ HCF, $1.0{\mu}L$ of fibrinogen and $2.0{\mu}L$ of thrombin. These six centrifuge tubes were filled with 1.0 mL of PBS and stirred in the water-filled beaker at 50 rpm. At 1, 3, 5, 7, 10, and 14 days, 1.0 mL of solution in each tubes was collected and preserved at $-20^{\circ}C$ with adding same amount of fresh PBS. Enzyme-linked immunosorbent assay (ELISA) was done to determine in vitro release profile of NGF and its bioactivity was evaluated with neural differentiation of pheochromocytoma (PC12) cells. Results: The average concentration of released NGF in the group A and B increased for the first 5 days and then gradually decreased. Almost all of NGF was released during 10 days. Released NGF from two groups could promote neural differentiation and neurite outgrowth of PC12 cells and these bioactivity was maintained over 14 days. Conclusion: Controlled release system using NGF-HCF gel via NGF-delivering implant could be an another vehicle of delivering NGF to promote the nerve regeneration of dental implant related nerve damage.

We implemented the Drug-Pad Moxibustion Method in order to improve the conventional moxibustion therapy. This method is aimed to eliminate burning wounds and smoke, which are the defects of conventional moxibustion therapy. And we performed to verify the efficiency by comparing the Drug-Pad Moxibustion Method with the conventional Indirect Moxibustion Therapy. We measured the body heat and the lasting time of blood circulation improvement using thermography. The moxibustion therapy has two kinds of effects: The formers are pharmacological effects of the Moxa's vasodilators and antioxidants. The latters are thermal effects which cause improvement of the blood circulation. To remove the demerits without omission of above therapeutic effects, we extracted the vasodilators and antioxidant compounds from the Moxa-$CH_2Cl_2$ fraction Moxa-EtOAc and composed the moxibustion kit with $(Ba_{0.8}\;Sr_{0.2})_{0.996}\;Y_{0.004}\;TiO_2+0.5_{WT}\;SiO_2%$ Positive Temperature Coefficients Thermistor. The experimental demonstrations have been made by the stimulating the spot which is CV4(Kwan-Won), CV8(Shin-Guel), CV12(Jung-Wan) acupuncture points of the conception vessel meridian(CV). And stimulating time was one hour. We divided the subjects into 5 groups such as no stimulation group, conventional Indirect Moxibustion group, only Drug-Pad stimulation group, only heat stimulation group, and Drug-Pad Moxibustion group. In the different cases, we have measured the body heat in pre-stimulation, just after stimulation, 2 hours after, and 4 hours after. The body heats of the group who were stimulated by the Drug-Pad Moxibustion Method were increased by over the $2^{\circ}C$. And the body heats of the group who were stimulated by the Indirect Moxibustion Method were increased by average the $1^{\circ}C$. We have evaluated that the Drug-Pad Moxibustion Method is improvement on the conventional Indirect Moxibustion Method by the heat-increasing rate is 200% and the lasting time is 150% with the body heat of the abdominal region. In the conclusions, We have implemented the Drug-Pad Moxibustion Method and evaluated the efficiency of the Drug-Pad Moxibustion Method comparing with the conventional Indirect Moxibustion Method.

Systematic toxicological analysis (STA) means the process for general unknown screening of drugs and toxic compounds in biological fluids. In order to establish STA, in previous study we investigated pattern of drugs & poisons in autopsy cases during 2007~2009 in Korea, and finally selected 62 drugs as target drugs for STA. In this study, rapid and simple drug identification and quantitative analytical program by gas chromatography-mass spectrometry(GC-MS) was developed. The in-house program, "DrugMan", consisted of modified chemstation data analysis menu and newly developed macro modules. Total 55 drugs among 62 target drugs were applied to this program, they were 14 antidepressants, 8 anti-histamines, 5 sedatives/hypnotics, 5 narcotic analgesics, 3 antipsychotic drugs, and etc. For calibration curves, fifty five drugs were divided into four groups of range considering their therapeutic or toxic concentrations in blood specimen, i.e. 0.05~1 mg/l, 0.1~1 mg/l, 0.1~5 mg/l or 0.5~10 mg/l. Standards spiked bloods were extracted by solid-phase extraction (SPE) with trimipramine-D3 as internal standard. Parameters such as retention times, 3 mass fragment ions, and calibration curves for each drug were registered to DrugMan. A series of identification, semi quantitation of target drugs and reporting the results were performed automatically. Calibration curves for most drugs were linear with correlation coefficients exceeding 0.98. Sensitivity rate of DrugMan was 0.90 (90%) for 55 drugs at the level of 0.5 mg/l. For standard spiked bloods at the level of 0.5 mg/l for 29 drugs, semi quantitative concentrations were ranged 0.36~0.64 mg/l by DrugMan. If more drugs are registered to database in DrugMan in further study, it will be useful tools for STA in forensic toxicology.

The purpose of this study was to investigate the effects of diaphragmatic breathing on activation of trunk muscles of patients with low back pain. Diaphragmatic breathing may affect activation of trunk muscles. The assumptions are as follows: the crural diaphragm attatches to the lumbar vertebrae from L1 to L3, the voluntary downward pressurization of the diaphragm increases intra-abdominal pressure, and this increases the stiffness of the spine. Diaphragmatic breathing increases intra-abdominal pressure and the increased intra-abdominal pressure may contribute to the lumbar stability. Sixty patients with low back pain were randomly divided into two groups. Experimental group performed diaphragmatic breathing exercise with six breathing positions and control group performed only the breathing positions for five times per week during six weeks. % maximal voluntary contraction(% MVC) of trunk muscles on six breathing positions of experimental and control group was measured according to testing period of pre test, three weeks, and six weeks. The repeated measures of one-way ANOVA were used to analyze % MVC on trunk muscles of experimental and control group according to testing period. The results of this study were as follows: First, % MVC of right and left erector spinae in the right leg extension position indicated the statistically significant difference in experimental group which performed diaphragmatic breathing exercise rather than control group (p<0.05). Second, % MVC of right and left erector spinae in all-four positions indicated the statistically significant difference in experimental group which performed diaphragmatic breathing exercise rather than control group (p<0.05). Third, % MVC of right and left erector spinae, external oblique in the sitting position indicated the statistically significant difference in experimental group which performed diaphragmatic breathing exercise rather than control group (p<0.05). Fourth, % MVC of right and left erector spinae, external oblique in the standing position indicated the statistically significant difference in experimental group which performed diaphragmatic breathing exercise rather than control group (p<0.05). Fifth, % MVC of right and left erector spinae, external oblique in the supine position indicated the statistically significant difference in experimental group which performed diaphragmatic breathing exercise rather than control group (p<0.05). Sixth, % MVC of right and left erector spinae, external oblique in the lying on prone position indicated the statistically significant difference in experimental group which performed diaphragmatic breathing exercise rather than control group (p<0.05). In conclusion, as experimental group performed diaphragmatic breathing exercise according to the period of pre-test, post three weeks, and post six weeks, experimental group showed the greater significant effect on the activation of right, left erector spinae, and external oblique muscle. Diaphragmatic breathing exercise which resulted in activation of trunk muscles can be effective for managing the patients with back pain and should be utilized as the new therapeutic intervention.
