Herbal medicines are widely used as therapeutic products in many countries. Corni fructus (CF), the dried ripe sarcocarp of Cornus officinalis Sieb. et Zucc (Cornaceae), has been used for thousands of years in traditional medicine and has been reported to be effective for the prevention and treatment of various diseases, such as kidney diseases and diabetes. Recent research on CF has documented a wide spectrum of therapeutic properties, which include anti-inflammatory, ant-oxidative, immunomodulatory, and anti-cancer effects. However, there is no information on its safety. Therefore, in this study, the toxicity of water extract of CF to ICR mice was investigated. The mice received a single dose of water extract of CF (1,000, 2,000, and 5,000 mg/kg of body weight) via the oral route. Mortality, clinical signs, body weight changes, gross findings, and weights of the principal organs after 14 d were then assessed. The results revealed no adverse effects of CF as determined by clinical signs, body weights, or organ weights and no gross pathological findings in any of the treatment groups. These results suggest that the 50% lethal dose and approximated lethal dose of CF extract is over 5,000 mg/kg. The findings provide scientific evidence for the safety of CFs.

In order to detect the safety and effect of various aqua-acupunctures from Scutellariae Radix, the modifications of boiling, filtration and dilution were employed for the manufacture of aqua-acupunctures. We injected 0.2cc of aqua-acupunctures into Joksamri (足三里) of rat, repeatedly. We compared subacute toxicity of them with saline group, distilled water(D.W.) group, acupuncture group and control group. The results were summarized as follows: 1. The groups were all healthy and alive, and there was no special abnormality in physical condition and autopsy. And there were not any toxic symptoms in repeating application of aqua-acupunctures to the rat, including changes of body weight, organ weight, haematological examination and serum biochemical test. 2. There was slight change of body weight in acupuncture group : We could see significance after 3 days(p<0.05) and after 7 days(p<0.001) in body weight loss. After 9 days, all tested groups were suppressed in body weight increment. 3. Result of organ weight : In Palkang aqua-acupuncture(D-2 group), saline group and acupuncture group there were some statistical significance. Especially, acupuncture group revealed significant result in liver and spleen than aqua-acupunctures. From this result, we could suggest that the efficacy of acupuncture was preceded herbal medicine. 4. In serum biochemical test, we examined glucose(GLU), triglyceride(TG) and cholesterol(CHOL). In comparison with control group, the diluted 10 times of Hwanggum aqua-aqupuncture$({\times}10\;group)$ was recognized significant decrease of glucose, but the diluted 100 times of Hwanggum aqua-acupuncture$({\times}100\;group)$, D-2 group, saline group were confirmed significant increment. There was not any meaningful change of CHOL in all of tested group, excepting the acupuncture group was exhibited statistically significant decrease(p<0.05). In TG level all tested group except complex injection of standard compound(CPA group) and HG, there were significant value iii statistically. The diluted solution was more significant decrease than Hwanggum aqua-acupuncture(HG). The mutual relationship of components of aqua-acupunture tended to decrease level of TG, regardless of its concentration. In acupunture guoup, we gained some interesting result In meaningful decrease in 7G. 5. Haematological examination showed significant increment of granulocytes(GR) in all tested groups except Hwanggum aqua-acupuncture. And the diluted solutions of HG expressed very high increment of them(p<0.001). The GR and Mean Corpuscular Volume(MCV) of acupuncture group showed statistical significance.
2,3,7,8-Tetrachlorodibenzo-p-Dioxin (TCDD), a ubiquitous environmental contaminant, causes a variety of adverse effects on the male reproductive system in rats. The effect of green tea extract (GTE) was investigated on the testicular function in Spragure-Dawley rats after a single exposure of 10$\mu\textrm{g}$ TCDD/kg body weight. The exposure of rat to TCDD significantly increased the weights of the epididymis and ventral prostate, yet significantly decresed the weight of the seminal vesicle when compared to the controls (p<0.05). In a combined treatment of TCDD with GTE, the organ weight changes caused by TCDD treatment disappeared. Significant decreases in sperm motility and sperm numbers were observed in the TCDD-treated rats, when compared to the control (p<0.05). GTE treatment reversed the decrease of sperm motility and sperm numbers caused by TCDD. There were no differences in sperm morphology, histological changes of the reproductive organs, and spermatogenesis between all the treated groups. In the ventral prostate and seminal vesicle, TCDD increased the CYP1A1 mRNA level, however, it did not affect the estrogen receptor $\beta$ (ER-$\beta$) mRNA level. GTE treatment did not influence the effect of TCDD on the levels of CYP1A1 and Er-$\beta$ mRNA. These results seem to indicate that green tea protects the testicular function against TCDD-induced reproductive toxicity, not because of a receptor-mediated mechanism but rather due to a secondary change of testes or accessory sex organs.
The current study was conducted to confirm the anti-cancer effect of Sarijang, which is a mixture of extracts from purple bamboo salt, Rhynchosia nulubilis, garlic, and Ulmi cortex. Nude mice were injected with a human-derived colorectal cancer cell (HCT116 cell line) and subsequently administered Sarijang for 4 weeks, following which the body weight, organ weight, and tumor size were measured. To evaluate the anti-cancer mechanism of Sarijang, the levels of p16 and extracellular signal-regulated kinase (ERK), cell cycle regulators in colorectal cancer, were measured. To evaluate the toxicity of Sarijang on liver and kidney, aspartate transaminase, alanine transaminase, blood urea nitrogen, and creatinine were analyzed. Sarijang not only reduced the tumor size by enhancing p16 and suppressing ERK, but also showed no side-effect in the liver and kidneys. Taken together, Sarijang has the potential to inhibit tumor growth without side effects, and may be used as a useful functional food.

This study was undertaken to investigate the effects of Gyoaesamultang in pregnant rats and their fetuses. Female Sprague-Dawley rats were orally administered with the Gyoaesamultang at dose of 5mg/kg/day for 20 days. Pregnant rats were sacrificed at 20th day of gestation, and observed internal and reproductive organs. Approximately, live fetuses in the 20th day of gestation were randomly selected and fixed in 95% ethanol. To observe skeletal malformations, fetuses were stained with alcian blue and alizarin red S. Maternal body weight of Gyoaesamultang treated group has a tendency to increase compared to that of control group. There were no significant difference in internal and reproductive organs. There were no significant changes between two groups in blood chemistry and hematological values. There were no significant changes in number of corpus luteum, implantation, live fetuses and implantation rate, delivery rate, late resorption rate and sex ratio. But Gyoaesamultang administered group showed lower early resorption rate than the control group. Neonatal body weight and number of fetus of Gyoaesamultang group were increased to that of control group. The fetuses of dams treated with Gyoaesamultang didn't showed external malformation. Vertebral and sternal variations were observed in Gyoaesamultang group but, compared to the control, those variations were insignificant. The number of ribs, cervical, thoracic, and lumber were normal. The number of sacral and caudal vertebrae were increased. Fetuses treated with Gyoaesamultang showed significant difference in the number of caudal vertebra(P<0.01). From these results, it can be concluded that Gyoaesamultang showed no toxicity effects on maternal body weight, early resorption rate, and number of live fetuses. There were no significant changes in organ weight, hematological data, reproductive organs. Although skeletal variations were showed in vertebrate and sternum, Gyoaesamultang were shown insignificant changes in bone malformation.
The experiments were undertaken to evaluate the effects of herbal medicine, Bojungiggitang and Gwibitang in pregnant rats and their fetuses. Female Sprague-Dawley rats were orally administered with the Bojungiggitang and Gwibitang at dose of 5ml/kg/day for 20 days. Pregnant rats were sacrificed at 20th day of gestation, and the internal and reproductive organs. Approximately live fetuses in the 20th day of gestation were randomly selected and fixed in 95% ethanol. To observe skeletal malformations, fetuses were stained with alcian blue and alizarin red S. Maternal body weights of Bojungiggitang and Gwibitang treated group has a tendency to increase compared to that of control group. There were no significant differences in internal and reproductive organs. There were no significant changes between two groups in blood chemistry and hematological values. There were no significant changes in number of corpus luteum, implantation and live fetuses. But Bojungiggitang and Gwibitang administered group showed higher implantation rate than the control group. Also, Bojungiggitang and Gwibitang administered groups showed lower early resorption rate than the control group. And Gwibitang had the higher value in all the other groups in all items. From the sex ratio, the number of females were larger than the number of males in the control group, and more males than females in Gwibitang administered group. Neonatal body weight and the number of fetus of Bojungiggitang and Gwibitang group were higher than that of control group. The fetuses of dams treated with Bojungiggitang and Gwibitang did not show external malformation. Vertebral and sternal variations were observed in Bojungiggitang and Gwibitang administered group compared to the control group. Those variations were insignificant. There were no significant changes in number of ribs, cervical, thoracic, lumbar, sacral and caudal vertebras. From these results, it can be concluded that Bojungiggitang and Gwibitang showed no toxic effects on maternal body weight and the number of live fetuses. There were no significant changes in organ weight, hematological data, and reproductive organs. Although skeletal variations were shown in vertebra and sternum, Bojungiggitang, Gwibitang were shown insignificant changes in bone malformation.
This study was conducted to investigate the antitoxic component in aqueous extract of Houttuynia cordata $T_{HUNB}$. The results were as follows: Generally, detoxication effects by Houttuynia cordata $T_{HUNB}$ extract increased in proportion to the extract concentrations. When 40mg/kg dosage of Houttuynia cordata $T_{HUNB}$ extract was administered, it showed the highest antitoxic effects in metallothionein induction. After the extract treatment, body weights increased in proportion to the extract concentration. However, after 3 weeks, the body weight decreased insignificantly. From the above results, Houttuynia cordata $T_{HUNB}$ extract increased metallothionein concentration and decreased the toxicity of cadmium in rats.
Objectives : This study was carried out to investigate the anti inflammatory and anti allergy effects of Vitex rotundifolia Linne fil. extract(VRE). Results : 1. In vitro test, VRE was used to determine the modulation of cytokine secretion, the activation of inflammatory and allergic factor and the inhibition of gene expression. The cell survival rate of Raw 264.7 and Jurkat T cells didn't decrease and accordingly cytotoxicity wasn't observed. In anti-allergic assay, the secretion of IL-2, TNF-${\alpha}$, IL-4, IL-5 and IFN-${\gamma}$ were suppressed on Jurkat T cells induced by dust mites. And the gene expression of COX-2 was suppressed in HMC-1 stimulated by calcium ionophore A23187. In anti-inflammatory assay, the gene expression of TNF-${\alpha}$, COX-2 were suppressed on LPS-activated Raw 264.7 cells. And the secretion of IL-6 and IL-8 were suppressed on EoL-1 cells induced by dust mites. P38 and ERK activation of MAPK decreased generally. VRE showed potent inhibitory activity of NO production. 2. In vivo test, we used NC/Nga mouse induced by atopic dermatitis to observe the effects of VRE on the weight, water and feed, blood test, weight of organs, total IgE and histological change of main organs. Quantity of water and feed were not changed, therefore it didn't affect the weight directly, and no change was observed in related main organs, thus maybe there is no organ toxicity by test substances. And the symptoms were decreased significantly, and the thickness of epithelial cell layer and the number of mast cells were inhibited significantly by the difference of dosage. The number of total complete blood cells and IgE in serum were not changed significantly. Conclusion : These results suggest that VRE has anti-inflammatory and anti-allergic effects. Therefore VRE could be used effectively on improvement or treatment of atopic dermatitis. However, further study is needed to prove which component of VRE indicates effective pharmacological action.

The experiments was undertaken to evaluate the effects of herbal medicine, Dalsaengtang, in pregnant rats and fetuses. Female Sprague-Dawley rats were orally administered with the Dalsaengtang at dose of 5 mg/kg/day for 20 days. Pregnant rats were sacrificed at 20th day of gestation, and observed internal and reproductive organs. Approximately live fetuses in the 20th day of gestation were randomly selected and fixed in 95% ethanol. To observe skeletal malformations, fetuses were stained with alcian blue and alizarin red S. Maternal body weight of dalsaengtang treated group has a tendency to increase compared to that of control group. The relative liver and kidney weights of dalsaengtang treated group were also increased to that of control group. There were no significant changes between two groups in blood chemistry and hematological values. There were no significant changes in number of corpus luteum, implantation, live fetuses and implantation rate, delivery rate, late resorption rate and sex ratio. But Dalsaengtang administered group showed lower early resorption rate than the control group. From the sex ratio, number of females, bigger than number of males in the control group, and more males than females in Dalsaengtang administered group. Neonatal body weight and number of fetus of Dalsaengtang group were increased to that of control group. The fetuses of dams treated with Dalsaengtang didn't showed external malformation. Vertebral and sternal variations were observed in Dalsaengtang group but, compared to the control, those variations were insignificant. The number of ribs, cervical, thoracic, and lumber were normal. The number of sacral and caudal vertebrae were increased. Fetuses showed significant difference in the number of caudal vertebra (P<0.01). From these results, it can be concluded that Dalsaengtang showed no toxicity effects on maternal body weight, early resorption rate, and number of live fetuses. There were no significant changes in organ weight, hematological data, reproductive organs. Although skeletal variations were showed in vertebrate and sternum, Dalsaengtang did not shown significant changes in bone malformation.
This study was carried out to investigate the activity of nitrogen fixation and accumulation of heavy metal and inorganic matter in Vicia amoena community at lower region in Kumho riverside, including Youngchon, Chimsangyo, Paldalgyo, Talseochon and Kumhogyo. The contents of inorganic matter and heavy metal of Kumho riverside soil increased in the down stream in each organ of the plant growing in the riverside. Generally, V. amoena community showed rapid growth of shoot and high value of Top/Root ratio. V. amoena community showed higher water content of shoot at late growth stage and higher chlorophyll content. The root nodule of V. amoena community appeared in April and increased by 0.30, 0.27, 0.24, 0.06 and 0.14 g/plant, and nitrogen fixation activity of nodule attained 20.1, 16.8, 15.4, 8.5 and 5.3 μmol·C₂H₄·g fw nodule/sup -1/·h/sup -1/ for non-contaminated area Youngchon, Chimsangyo, Paldalgyo, Talseochon and Kumhogyo, respectively, in June:. Nodule formation and nitrogen fixation activity were reduced in the down stream by the soil contamination and heavy metal accumulation and showed minimum values. at Talseochon and Paldalgyo. V. amoena showed growth adaptation against heavy metal toxicity by restricting heavy metal such as Pb, Cu, Zn, Fe from transport, and by accumulating high Ca ion in shoot, nitrogen and phosphorus in root at late growth stage than those at early one, respectively, but total heavy metal per plant showed higher values in shoot than those in root by high T/R ratio of plant growth.
