Abstract

The hepatoprotective effect of Cordyceps militaris culture broth was determined using HaM/ICR strain mice. Compared to control, the intra-peritoneal injection of benzo($\alpha$)pyrene (B($\alpha$)P) remarkably increased the activities of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in the serum and the level of lipid peroxide (LPO) in liver tissue, which mean the liver was damaged by B($\alpha$)P. However, compared to B($\alpha$)P, oral administration of C. militaris culture broth showed decrement of AST, ALT, and LPO activities and increment GST activity and GSH level in liver tissue. These suggest that C. militaris culture broth recovered hepatic damage induced by B($\alpha$)P.

번데기동충하초의 간독성 회복 효과를 HaM/ICR 계열의 흰쥐를 이용하여 검정하였다. 벤조피렌 복강주사시, 혈중의 aspartate aminotransferase (AST) 및 alanine aminotransferase (ALT)의 효소활성과 간조직의 lipid peroxide (LPO) 농도는 대조군과 비교시 급격히 증가하여 간독성을 유발하였다. 그러나, 벤조피렌 대조군과 비교시, 번데기 동충하초 배양액의 경구 투여시 AST와 ALT의 효소활성 및 LPO 농도는 감소하였으며, 벤조피렌에 유도된 간 조직의 glutathione 농도 및 glutathione S-transferase 효소활성은 증가하여 간독성을 회복하였다. 실험결과는 번데기 동충하초 균사체 배양액이 벤조피렌 유발 간독성에 대해 회복 효과가 있음을 보여준다.
