사염화탄소의 장기(長期) 투여(投與)로 유발된 백서(白鼠) 간경변(肝硬變)에 대한 형방지황탕(荊防地黃湯)의 조직병리학적 영향

Objective : This study was carried out to investigate the effects of oral administration of Hyeungbangjihwang-tang (HBJHT) on the liver cirrhosis of rats induced by Carbon tetrachloride for 10 weeks. Method : The histopathological changes were observed. The HBJHT extracts were daily dosed at 50, 100 and 200mg/kg for 12 weeks. Results : Severe hepatocellular necrosis and ballooning, hyperplasia of connective tissue, subdued reduction of hepatic lobule, and hyperplasia of bile duct in portal triad were dramatically decreased in the HBJHT-treated group compared to that of the Carbon tetrachloride-treated control group in histopathological observation. The diameter of hepatic lobules was significantly enlarged in the HBJHT-treated group compared to that of the Carbon tetrachloride-treated control group, and the amounts of connective tissue, degenerative cells and bile ducts were significantly and dose-dependently decreased. Conclusion : It is concluded that HBJHT has a significant recovering effect on the liver of rats induced by carbon tetrachloride.
