Abstract

This study determined the effect of Lespedeza Caneata extract on the livers and kidneys of lead-administered mice. The experimental groups were divided into a normal group, Pb 4W group, Pb-LC 4W group, Pb 8W group, and Pb-LC 8W group. The normal group was supplied single distilled water, and the pb group was provided distilled water in which lead acetate was dissolved at 1,000 ppm. The Pb-LC group was provided with lead as drinking water, and the Lespedeza Caneata was orally medicated at a concentration of 500 mg/kg daily. AST, ALT, and BUN enzyme activities and histological experiments on the livers and kidneys resulted in the following conclusions. AST, ALT, and BUN activities increased in the experimental group compared to the normal group and decreased more in the Pb-LC group than the pb group during the same period. The histological results reveal that portions of the livers and kidneys were deformed in the Pb 4W group, and most of the Pb 8W group experienced necrosis and deformation. pb-LC4W and Pb-LC 8W groups experienced less deformation than the Pb 4W and Pb 8W groups. During the same period, the Pb-LC group experienced less histological changes than the Pb group. These results suggest that Lespedeza Caneata extract may have some protective effect on hepatic tissue and renal tissue damage with lead-administered in mice.

본 연구는 야관문 추출물이 납 투여된 생쥐의 간장과 콩팥에 미치는 영향을 알아보고자 시행하였다. 대조군(Nor), 납 단독투여 4주군 (Pb 4W), 납 단독투여 8주군 (Pb 8W), 납-야관문 복합투여 4주군(Pb-LC 4W), 납-야관문 복합투여 8주군(Pb-LC 8W)으로 나누어 구분하였다. 대조군은 1차 증류수를, 납 단독투여군은 lead acetate를 증류수에 1000ppm으로 용해하여 식수로 공급하였다. 납-야관문 복합투여군은 납을 식수로 공급하면서 야관문을 500 mg/kg 농도로 매일 경구투여 하였다. 혈액의 AST, ALT, BUN 효소활성과 간장, 콩팥의 조직학적 실험을 하여 다음과 같은 결론을 얻었다. AST, ALT, BUN는 대조군에 비해 실험군 모두 증가하였고, 같은 기간의 납 단독투여군 보다 납-야관문 복합투여군에서 수치가 감소하였다. 조직학적 결과는 간장과 콩팥에서 Pb 4W군은 일부가 변형되었고 Pb 8W군은 대부분에서 괴사와 변형이 일어났고 Pb-LC 4W군과 Pb-LC 8W군은 Pb 4W군과 Pb 8W군 비해 변형이 완화되었다. 같은 기간의 납 단독투여군 보다 납-야관문 복합투여군에서 조직 변화가 완화되었다. 이상의 연구결과로 보아 야관문 추출물이 납 투여한 생쥐의 간장과 콩팥의 손상에 대한 보호 효과가 있다고 사료된다.
