  • This study was conducted to investigate the effects of black raspberry wine which was administered per os on estrogen levels in Splague-Dawley(SD) rats. Black raspberry wine containing 13% alcohol(v/v) was prepared from ripe fruits of Rubus coreanus fermented with Saccharomyces cervisiae. The rats were divided into 2 groups(A and B): The group A received black raspberry wine and the group B received saline for 7 weeks. All animals were bi weekly monitored for estrogen levels by radioimmunoassay using $125^I$ labeled anti-estrogen monospecific antibody. There was a significant(2.02 fold) increase in estrogen levels in the group A with a peak at the 7th week post administration of black raspberry wine. There was no significant change in estrogen levels of the rats in the group B. These data point to uncharacterized phytoestrogenic bioactivity of black raspberry wine that appears to be a useful phytoestrogenic herbal remedy for human health.

  • To study the effect of Kamidaebotang on the hypothyroidism induced by thiourea in SD(Splague Dawley) rats, the weight of thyroid gland, the level of serum $T_3\;and\;T_4$. total cholesterol, hematological changes and histopathological findings were measured. The following results were obtained. 1. Thyroid gland weight of the Kamidaebotang B treated group was significantly increased as compared with that of control group(p<0.05). 2. The level of serum $T_3$ of the Kamidaebotang B treated group was slightly increased as compared with that of control group. But no significant changes appeared between two groups. 3. The level of serum $T_4$ of the Kamidaebotang A, B treated groups were significantly increased as compared with that of control group(p<0.05). 4. Total cholesterol of the Kamidaebotang A, B treated groups were not significant changes as compared with that of control group. 5. Hematological data of the Kamidaebotang A, B treated groups were not significant changes as compared with that of control group. 6. Histopathologically, Kamidaebotang B administration recovered effectly the dystropy, degeneration of thyroid follicle induced by thiourea. From above results, it is suggested that Kamidaebotang B is available to the hypothyroidism induced by thiourea in rats. Therefore, Kamidabotang B seems to be applicable to hypothyroidism in clinical practice.

  • In order to establish the experimental clinical model for evaluating the influences on the sexual hormones of SD-rat administrated with Methoxychlor(MET), it was dissolved in acetone and olive oil (1:19), which was administrated orally at doses of 200㎎/㎏ body weight/day for 7 days. The Testosterone value was measured in sera by Gamma Count with 1251 isotype, also weights of the body, testis and liver were measured for 15 weeks. Testosterone in the serum of intacted SD-rats was 0.51±0.43ng/㎖(n=5), but it was 0.69±0.18(n=2)ng/㎖l on 1 week. 0.28±0.05ng/㎖(n=2) on 3 week, 1.52±0.95ng/㎖(n=3) on 5 week, and 0.54±1.95 ng/㎖(n=3) 15 week post-dosing MET, respectively. Histologically, the numbers of spermatozoa and Leydig cells were reduced, which might influence to reduce sexual hormone, and AST and ALT was not increased in the serum due to administrating with MET, blood profile was not changed according to the administration of MET excepting MCH(Mean Corpuscular Hemoglobin). This study suggest that change of male sexual hormone by MET be a experimental model for evaluating some drugs associate with sex hormone.
