Abstract

This study was carried out to investigate the effects of Rhynchosia molubilis saponin on carbon tetrachloride ($CCl_4$)-induced hepatotoxicity. Sprague-Dawley rats were intraperitoneally administered the Rhynchosia molubilis saponin at 100 mg/kg every day for two weeks, then $CCl_4$ (3.3 ml/kg) was injected into rats. 12 hours later, they were anesthesized with ether and dissected. Rhynchosia molubilis saponin-administered group showed 59.92% and 62.28% of inhibitory effects on aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities compared to $CCl_4$-treated group (p<0.05). Malonedialdehyde (MDA) levels of Rhynchosia molubilis Saponin-administered and $CCl_4$-treated (RSC) group in liver homogenate and mitochondria were significantly inhibited to 61.83%, 81.11 %, respectively, compared to $CCl_4$-treated group (p<0.05). Superoxide dismutase (SOD) activities of RSC group in liver homogenate and mitochondria were significantly inhibited to 66.53%, 31.04%, respectively, compared to $CCl_4$-treated group (p<0.05). GPx activities of RSC group in liver homogenate and mitochondria were significantly inhibited to 72.74%, 72.68%, respectively, compared to $CCl_4$-treated group (p<0.05). The histological examinations showed that the liver cell necrosis and centrilobular congestion aggregation induced by $CCl_4$ were dearly eliminated by the administration of Rhynchosia molubilis saponin. These results suggest that Rhynchosia molubilis saponin could have the protective effects against hepatotoxicity.

이 연구는 $CCl_4$로 유도된 간독성에 노두 사포닌의 간 보호 효과를 연구하기 위해 수행되었다. SD-Rat를 2주 동안 노두 사포닌 100 mg/kg이 되도록 복강 내에 투여하였다. 14 일째, $CCl_4$를 투여하고 12시간 후에 에테르 마취 후 간과 혈청을 분리했다. AST, ALT는 대조군에 비해서 노두 사포닌군이 65.56%와 59.04%로 억제되었다. MDA 수치는 대조군과 비교해서 노두 사포닌군의 간 homogenate에서 53.74% 억제되엇고 미토콘드리아에서는 89.86% 억제 되었다. SOD의 활성은 대조군과 비교해서 노두 사포닌군의 간 homogenate에서 42.51 % 억제되었고, 미토콘드리아에서는 38.42% 억제되었다. GPx의 활성은 대조군과 비교해서 노두 사포닌 군의 간 homogenate에서 72.74% 억제되었고, 미토콘드리아에서는 72.68% 억제되었다. $CCl_4$으로 나타난 간세포의 괴사와 울혈이 노두 사포닌군 에서는 조직실험결과 감소되는 것으로 나타났다. 모든 데이터는 $CCl_4$로 유도된 간독성을 노두 사포닌이 보호하는 결과를 보였으며, 이는 간독성에 대한 보호효과를 가진 약물 소재 개발에 이용될 수 있다.
