In the chickens removed the left thyroid gland or administrated with thiouracil, fatty liver (FL) and fatty liver-hemorrhagic syndrome (FLHS) were induced within five weeks after treatment. FL was observed in all of the thyroidectomized layer and broiler hens, and the occurrence of FLHS was higher in rate at the fifth week than that at the third week after removal. FL and FLHS were observed in the thiouracil-administrated broiler hens, but the rate of incidence was appeared to be lower in the thiouracil-administrated hens than in the thyroidectomized chickens. It was suggested that hypothyoidism could be an important factor inducing FLHS.

Objectives : In order to study experimentally the effects of Woogwi-eum(Yougui-yin) on hypothyroidism, ${T_3}-uptake$ content, $T_3$ content, $T_4$ content, TSH content, hematological values, enzyme activity, total cholesterol content, $Na^{+}$ content change in the serum and body weight of rats induced by thiouracil were measured after medication of extract of Woogwi-eum (Yougui-yin). Methods : Sparque-Dawley rats were used in this experiment and the rats were divided into normal, control and experimental groups. The hypothyroidism of control and experimental groups was induced by thiouracil, Woogwi-eum(Yougui-yin) extract was orally administered in the experimental groups for 20 days Results : In this experiment, the Woogwi-eum(Yougui-yin) treated group showed a significant increase in the serum ${T_3}-uptake$, TSH, RBC and hematocrit content, whereas a significant decrease in the serum CPK, ALP, LDH, total cholesterol content and the body weight was measured. Conclusions : According to the above results, it is suggested that Woogwi-eum(Yougui-yin) is partially effective to the hypothyroidism induced by thiouracil in rats. Therefore, Woogwi- eum(Yougui-yin) seems to be applicable to hypothyroidism in clinical practice.

In order to determine the effects of Palmijihwangtangs on the hypothyroidism, the biochemical and morphologic effects of PALMIJIHWANGTANGS against 2-thiouracil-induced hypothyroidism in rats were examined. 1. Serum $T_3$ value was significantly incresed by the treatment with PALMIJIHWANGTANG-1, 2 and 3(p<0.05). 2. Serum $T_4$ value was significantly higher in PALMIJIHWANGTANG-1 and PALMIJIIIWANGTANG-2 treated groups than that of control group. In PALMIJIHWANGTANG-3 treated group, serum $T_4$ level was significantly higher and that of control group(p<0.01). 3. Scrum free $T_4$ value was significantly incresed in the PALMIJIHWANGTANG-1 and PALMIJIHWANGTANG-2 treated groups(p<0.05) 4. Total cholesterols was significantly decresed by the treatment with PALMIJIHWANGTANG-1(p<0.05). 5. The treament with the PALMIJIHWANGTANG-1, 2 and 3 resulted in the significantly decrease of serum ALT(p<0.05). 6. Thyroid gland weight was significantly increased in PALMIJIHWANGTANG-3 treated group(p<0.01). 7. Treatment with PALMIJIHWANGTANG-1, 2 and 3 effectively recovered the dystropy and degeneration of follicle in thyroid gland caused by 2-thiouracil. 8. There was no histological and functional lesion observed in the liver after treatment with PALMIJIHWANGTANG-1, 2 and 3. These results suggest that PALMIJIHWANGTANG may be effective in the treatment of hypothyroidism.

Objective : Although hypothyroidism is a common disease in the endocrinology system, it is reported that there are a lot of difficulties in treating it effectively. Aconiti Ra얕 traditionally has been used in treatment of coldness, fatigue, and bradycardia. In this study, we investigated the therapeutic effects of Aconiti Radix on hypothyroidism rat model induced by 6-propyl-2-thiouracil (PTU). Methods : Two-month-old rats were used with administration of PTU which induced hypothyroidism in the rats. After 2 weeks, Aconiti Radix and thyroxine were administered, respectively. The body weights were measured every week. After 4 weeks, the blood samples of all rats were taken from their hearts. They were analyzed biochemically and $T_4$ (thyroid hormone) & TSH (thyroid stimulating hormone) was measured by ELISA kits. Results : In comparison with normals, controls showed hypothyroidism with significantly low $T_4$ and high TSH the statistics. In Aconiti Radix administration groups significantly increased $T_4$ was observed in the statistics and its effects were dose-dependent. There was no difference statistically in TSH of Aconiti Radix treatment groups from controls, nor were statistical differences observed significantly in biochemical labs and weight of each group. Conclusions : These findings suggest that Aconiti Radix protects thyroid cells and makes thyroid cells produce thyroid hormones. It is also very safe in the view of liver, kidney function, and other metabolism. It may be a useful agent for treating hypothyroidism.

Objective : The aim was to study experimentally the effects of Daeyoungjeon(DYJ) on the hypothyroidism of rats induced by thiouracil. Methods : Spargue-Dawley rats were separated into four groups. Except normal group, the other three groups were treated with thiouracil 0.50g/kg/days for 30 days by oral administration. Among the three groups, one group was treated DYJ extract 0.75g/kg/days for 20 days separately. Another group was treated DYJ extract 1.50g/kg/days for 20 days separately. T3-uptake, T3, T4, TSH, hematological values, enzyme activity, total cholesterol, triglyceride and Na+ content change in the Serum of rats were measured after medication of solid extract of DYJ. Results : As a result of this study, in the serum T3-Uptake and T4 level, hematological values and sodium were increased in DYJ group compared to control group. The serum TSH, total cholesterol, triglyceride, enzyme activity and body weight were decreased in DYJ group compared to control group. Conclusion : According to the above results, it is suggested that DYJ is effective to cure hypothyroidism.
