  • 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.

  • Objectives This study was aimed to evaluate the effects of Daeyoungjeon (hereinafter referred to DYJ) treatment on the injury of articular cartilage induced by monosodium iodoacetate in rats. Methods Twenty-four male rats were divided into normal, osteoarthritic control and DYJ group. Rats of normal group were injected with 0.1 ml physiological saline, rats of control and DYJ groups were injected with 0.1 ml monosodium iodoacetate (3 mg/ml) into each left and right knee joint cavities. Rats of DYJ group were administrated extracts of DYJ during 60 days per orally. At 60 days after treatment, gross lesions, area and proteoglycan contents of articular cartilage, histopathological lesions, immunohistochemistry on matrix metalloproteinases (MMP-2, MMP-3, MMP-7) were evaluated. Results Grossly, degenerative changes of articular cartilages were observed weak in DYJ group. The areas of articular cartilages were broader significantly in DYJ group. The proteoglycan contents in articular cartilages were lesser significantly in DYJ group. Histopathologically, the chondrocyte score was lesser significantly in DYJ group. MMP-3 expression in articular cartilages was observed weak in DYJ group. Conclusions From above results, DYJ treatment has inhibitory effects on the injuries of articular cartilage induced by monosodium iodoacetate in rats, and it's effects may be related with down regulation of MMP-3.
