  • The subcronic toxicity of BDR-29, a herbal preparation of Cassiae Semen, Prunellae Spica, Tribuli Fructus, and Uncariae Rhamulus et Uncus, was examined in male and female Sprague-Dawley rats. Rats were treated with the test substance at a dose 5 mg/kg, 50 mg/kg and 500 mg/kg intragastrically for 13 weeks. No death and abnormal clinical signs were observed throughout the administration period. There were not significantly different from control group in net body weight gain, food and water consumption, organ weight, gross pathological findings, and urine analysis among the groups rats treated with different doses of the BDR-29. Hematological findings and biochemical examination revealed no evidence of specific toxicity related to BDR-29. From these results, no observation effect level (NOEL) of BDR-29 is 500 mg/kg/day under the condition employed in this study.

  • This study was carried out to know the effect of Geopungjeseup-tang(GPJST) to on Rheumatoid Arthritis by using human fibroblast-like synoviocytes(hFLS). GPJST consists of Coisis Semen, Coccllus Trilobus DC., Lycopi Herba, Arisaematis Rhizoma. The author peformed several experimetal items : that is cytotoxicity of GPJST, mRNA expression of TNF-${\alpha}$, IL-1${\beta}$, ICAM-1, production of NO. The results were obtained as follows : The mRNA expression of pro-inflammatory cytokines TNF-${\alpha}$, IL-1${\beta}$, ICAM-1 were dose-dependently reduced in hFLS. The production of NO was reduced. Talking all these observations into account, GPJST is considered to be effective in treating rheumatoid arthritis. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

  • Rosa rugosa has been used as a folk medicine with various pharmacological properties for a long time in Asia. Recently, it has been reported that the extract of fractions from different parts of Rosa rugosa have various pharmacological effects on diverse diseases including diabetes, inflammatory diseases and tumor. We investigated effects of fructus extracts of Rosa rugosa(RRF) and semen extracts of this herb(RRS) on macrophage to evaluate the possibilities as a biological response modifier. We showed increased effects on tumoricidal activity, phagocytic activity, TNF-$\alpha$ and NO production in RRF-treated groups without direct tumor cell cytotoxicity. RRS-treated groups increased direct tumor cell cytotoxicity at high dose without tumoricial activity except increasing of TNF-$\alpha$ release. These results provide further possibilities for the beneficial immunomodulating effects of RRF on immune system with relatively larger safety margin rather than RRS.

  • To assay the fertilizing capacity of domestic animal spermatozoa by hamster test, semen were collected from 13 boars(Duroc. Landrace and Yorkshire) which had been proved to be fertile in the past. then, were preserved in BWW medium or in raw state at 18$^{\circ}C$ or at room temperature. The preserved semen were given each different treatment according to the experimental design and coincubated with zona-free hamster ova for 5 hours. The ova were stained by lacmoid and examined under phase contrast microscope to investigate the rates of ova bound with sperm(sperm binding). ova penetrated by sperm(penetration) and formation of a male pronucleus(pronucleus formation) and also numbers of both bound and penetrated sperm per ovum. Between BWW and TBM medium for boar sperm. no difference in the results of hamster test was obtained. The boar spermatozoa in BWW medium, BWW with caffeine, BWW with heparin, and BWW with both caffeine and heparin showed no difference in the results of hamster test. The boar spermatozoa in BWW medium containing both calcium and RSA showed considerably higher rates of sperm binding, penetration and pronucleus formation as well as higher numbers of both bound and penetrated sperm than those not containing calcium with or without BSA( p<0.01) and also the same results higher than that containing calcium without BSA( p< 0.05). The boar spermatozoa irradiated by X-ray(70 KVP, 20mA) for 3 seconds. then, maintained at 18$^{\circ}C$ for 18 hours showed considerably lower rate of sperm binding than all the other groups including the control and X-ray groups irradiated by smaller dose or maintained for shorter period(p<0.01), and also showed lower number of bound sperm than the other groups(p<0.01, p<0.05). All the control groups of both raw and diluted sperm in BWM medium showed higher rates of sperm binding, penetration and pronucleus formation as well as higher number of penetrated sperm than all the X-ray groups irradiated for 3 seconds(70KVP, 20mA) and maintained for either 3 or 18 hours (p<0.01, p<0.05). At the same time the control groups of diluted sperm showed considerably higher rates of sperm penetration and pronucleus formation than the control group of raw sperm( p<0.01). These results indicates that fertile boar sperm showed considerably lower rates In the results of hamster test, when incubated in the medium without calcium and irradiated by X-ray than when incubated in the medium with calcium and not irradiated by X-ray, respectively, to prove consequently that hamster test would be of great value in assaying the fertilizing capacity of boar spermatozoa.

  • SosokMyeongTang(SMT) have been used in oriental medicine for many centuries as a therapeutic agent for cerebral disease. The effects of SMT on the vascular system is not known. The purpose of this study was to investigate the effects of SMT on the changes in blood pressure(BP) and regional cerebral blood flow(rCBF) of rats. SMT consists of the following components : Radix Ledebouriellae(防風), Radix Cocculi or Stephaniae(防己), Semen Armeniacae(杏仁), Cortex Cinnamomi(肉桂), Radix Scutellariae(黃芩), Radix Paeoniae Lactiflorae(白芍藥), Radix Ginseng(人蔘), Rhizoma Cnidll(川芎), Herba Ephedrae(麻黃), Radix Glycyrrhizae(甘草), Radix Aconiti(附子?), Fructus Zizyphi Jujubae(大棗), Rhizoma Zingiberis(生薑) and the changes of BP and rCBF were tested Leser-Doppler Flowmetry(LDF) The experimental results were as follows ; BP was not affected by SMT in rats, but rCBF was increased significantly by SMT in a dose dependent manner. SMT increased previous decreasd rCBF due to pretreatment methylene blue, but did not increased previous decreasd rCBF due to pretreatment L-NNA, indomethacin. Pretreatment with indomethacin decreased BP compaired with control group. These results suggest that SMT causes a diverse response of blood pressure and regional cerebral blood flow(rCBF). The increased rCBF is mediated by nitric oxide synthease.

  • In this paper, we studied what the drug name of Sang-Baik-Pi(桑白皮) Mori Cortex Radicis) is, how to collect it; and how the chief symptoms had changed in the chinese medical references and herbological literatures and formularies. Also we bibliographically analyzed in the herbological way the drugs combinated with Sang-Baik-Pi and their active principles among the prescriptions in the famous medical book; 'Dong-Ui-Bo-Gam', (東醫寶鑑) of our country. Finally, we concluded as foolow. Numerous names of botainical origin were described, but it was not recorded that San-Keun-Baik-Pi(桑根白皮) in old days is different from root bark of Morus sp. in this times. Sang-Baik-Pi has been a common designation since Ming dynasty (AD 1500). Collections of it were independent of seasons, it could effect perfectly over 10 years old. And its cork layer should be removed after collections, it was especially emphacised that root bark on ground was poisonous. The chiefly cured symptoms with Sang-Baik-Pi were constantly not different from the contents of 'Shin-Nong-Bon-Chau-Kyung'(神農本草經) in ancient times, but it has been developed since Ming dynasty. Its uses are widely extended to a surgical and dermatologic desease; rheumatis, beriberi and diabetes in this times. and its efficacies depend upon curing. Prescriptions on Sang-Baik-Pi that were prescribed in 'Dong-Ui-Bo-Gam' are there, 177 drugs combinated with it. Glycyrrhizae Radix is most frequently combinated with Sang-Baik-Pi(frequently 68%). It is proved that Armeniacae Semen, Platycodi Radix etc, in the order take strong effects on anti-tussive, anti-phlogistic, diuretic, anti-pyretic etc. It is expressed 34 times, frequently, that a dose is 3.75g, and it shows that a usual doses is 2-4g. As the above prescriptions are classified, the results is as follows, respiratory tract desease is most frequently in 69 prescriptions, the next gastrointestinal tract 13 times, diuretic 12 times, and antipyretic 11 times. Therefore, Sang-Baik-Pi contains a good remedial value chiefly of the effects upon the respiratory diseases.

  • GCSB-5 is a purified extract from a mixture of 6 Oriental herbs (Ledebouriellae Radix, Achyranthis Radix, Acanthopanacis Cortex, Cibotii Rhizoma, Glycine Semen, and Eucommiae Cortex) that have been widely used for the treatment of inflammatory diseases in the East Asia. The aim of this study was to investigate the anti-inflammatory potential of GCSB-5. The animals used in this study were administered either vehicle or GCSB-5 (30, 100, 300, and 600 mg/kg) orally. The GCSB-5 significantly inhibited the increased of acetic acid-induced vascular permeability (30.9%-34.2% inhibition at 30-300 mg/kg). The swelling of the rat's hind paw induced by carrageenan was significantly inhibited by GCSB-5 in doses of 100, 300, and 600 mg/kg. Maximal inhibition (50.9%) was obtained with GCSB-5 at dose of 300 mg/kg. However, it did not have any anti-inflammatory action in the rheumatoid arthritis induced by Freund's complete adjuvant or in the granuloma induced by carrageenan. Our finding suggest that GCSB-5 has a anti-inflammatory activity.

  • There are the Seven Effect of Drugs and unique processing methods in Chinese traditional medicine. The Seven Effects are single effrect(單行), additive effect(相加, 相須), synergic effect(上乘, 相使), antagonistic effect(相畏, 拮抗), inhibitory effect(相惡), neutralizing effect(相殺) and opposite effect(相反). We are interested in synergic effects of some drugs and components ; Addition of OLDENLANDIA DIFFUSA to Kilkyungtang combanation enhanced the cytotoxic activity of Kilkyungtang against A549 and B16-Fo eells by 20% and 50%, respectively. The Oldenlandia-added kilkyungtang also potentiated the cytotoxicities of mitomycine Cand 5-fluorouracil. ar-tunnerone. isolated from the root of Curcuma longa, potentiated the cytotoxic activity of sesquiphellandrene(isolated from the same root), aurapten(isolated from Aurantii semen)or cyclophosphamide by 10 times. The purpose of the processing(修治) of Chinese grugs is to remove unusable parts of plants and to eliminate toxicities as well as to produse new active components in drugs. On a occasion of study on the anthelmintic drugs against the chinese fluke(Clonorchis sinesis, (肝디스토마), we have observed that the processed mume fruit(鳥梅) possessed a very very potent clonorchicidal effect, while the methanol extract of the non-processed fruit inactive. The active component was isolated from the processed mume and identified as 5-hydroxymethylfurfuryl aldehyde. This substance dose not occur in the immature fruit and was found only in the processed one. Wehave heated the immature fruit in an oven at $90^{\circ}C$ for 52 hrs and found that the heated fruit eame clonorchidal. As demonstrated in these and other example cited in this presentation, the natural products chemistry is contributory to univeiling the drug effect ensued from the processing and the synergic effect of Oriental medical drug combinations, and to rationalization or modernization of the traditional medicine.

  • This study was performed to determine the effects of nitric oxide on human sperm cell function. Semen samples were obtained from normal healthy volunteers. Motile spermatozoas collected by swim-up method were incubated up to 24 hours in Ham's F-10 medium supplemented with a various concentration of sodium nitroprusside (nitric oxide releasing agent). Sperm motility, hyperactivation, acrosome reaction rate, and acrosin activity were determined. The results are as follows; 1. 1mM of SNP resulted in a significant decrease in sperm motility ($44.8%{\pm}8.9%:78.1%{\pm}6.3%$, and hyperactivation $(10.4%{\pm}6.4%:47.7%:{\pm}9.5%)$ after incubation for 3 hours compared with the control group (Ham's F-10 alone), but had no effect on acrosome reaction. 2. At $100{\mu}M$ SNP, sperm motility was reduced after incubation for 6 hours $(54.8%{\pm}3.2%)$ compared with that of the control group $(82.7%{\pm}8.9%)$, but hyperactivation and acrosome reaction were not affected. 3. However, a lower concentration (less than $10{\mu}M$) of SNP had no effect on sperm motility and hyperactivation for 8 hours of incubation but significantly decreased them when incubation periods were increased up to 24 hours compared with the control group. On the other hand, $1{\mu}M$ and $10{\mu}M$ SNP significantly increased the acrosome reaction rate in both acrosomal status ($17.3%{\pm}5.2%$, $23.5%{\pm}4.7%$, respectively) and acrosin activity ($34.3{\mu}IU{\pm}10.5{\mu}IU,\;45.6{\mu}IU{\pm}5.6{\mu}IU$, respectively) as compared with the control group $(7.0%{\pm}4.0%,\;9.5{\mu}IU{\pm}3.4{\mu}IU)$. These results indicate that SNP, NO releasing agent, has a dose-dependent effects on the sperm cell function. Therefore it may positively affect the fertilization by promoting acrosomal reaction at a lower concentration (less than $10{\mu}M$).

  • Objectives: This study was carried out to analyze the single-dose toxicity of Eun-Bi San pharmacopuncture injected into the muscle of Sprague-Dawley (SD) rats. Methods: All experiments were performed at Biotoxtech, an institution certified to conduct non-clinical studies under the Good Laboratory Practice (GLP) regulations. Six week old SD rats reared by ORIENTBIO were chosen for this pilot study. The reason SD rats were chosen is that they have been widely used in safety tests in the field of medicine, so the results can be easily compared with many other databases. The Eun-Bi San pharmacopuncture was made in a clean room at the Korean Pharmacopuncture Institute (KPI, K-GMP). The constituents of the Eun-Bi San pharmacopuncture are Angelicae gigantis radix, Strychni semen and Glycyrrhizae radix. These were extracted at low temperature and low pressure in an aseptic room at the KPI. Doses of Eun-Bi San pharmacopuncture, 0.25, 0.5 and 1.0 mL, were administered to the experimental groups, and a dose of normal saline solution, 1.0 mL, was administered to the control group. This study was performed under the approval of the Institutional Animal Ethics Committee of Biotoxtech Co., Ltd. Results: No deaths or abnormalities occurred in any of the four groups. No significant changes in weight, hematological parameters or clinical chemistry between the control group and the experimental groups were observed. To determine if abnormalities existed in any organs and tissues, we used microscopy to examine representative histological sections of each specified organ; the results showed no significant differences in any of the organs or tissues. Conclusion: The results of this study suggest that treatment with Eun-Bi San pharmacopuncture is relatively safe and that its clinical use may be beneficial. Further evaluations and studies on this subject will be needed to provide more concrete evidence in support of these conclusions.
