Abstract

This study was carried out to investigate effect of serum lipid and liver tissue in lectin from Viscum album on rats. The lectin was purified by sepharose 4B affinity chromatography and gel filtration using sephadex G-150 with plant material from Viscum album. After 72 h of $CCl_4$ injection, there was a significant increase in serum total cholesterol and triglycerige levels relative to the control group. However, treatment of both Viscum album and purified lectin were significantly decreased lipid parameters against the $CCl_4$-induced. Histological observation of the liver section of rats challenged with $CCl_4$ produced a marked increase of cytoplasmic vacuoles in number, while rats administered olive oil alone did not alter the normal hepatic architecture. Histological observation of the liver section in rats treated 72 h with either Viscum album purified lectin or $CCl_4$-induced liver lipogenesis showed decreased numbers of cytoplasmic vaculoes and necrotic cells. These results suggest that Viscum album lectin has a significantly decreased lipid in serum or histological observation of the liver section decreased in lipogenesis in rats.

본 연구에서 국내산 겨우살이 lectin이 흰쥐 간의 지방형성에 미치는 영향을 알아보기 위해 혈청 내 지질 함량을 측정하였고, 이를 확인하고자 간조직의 지방형성 변화를 조사하였다. 렉틴의 분리는 sephadex G-150로 여과 및 sepharose 4B affinity chromatography 로 정제하였다. $CCl_4$를 복강 내에 투여시 72시간 경과 후 혈청 총cholesterol 및 triglyceride는 정상군 및 olive oil 투여군에 비해 유의하게 증가하였으며, lectin과 $CCl_4$를 동시 투여 하였을 때는 유의한 감소를 나타내였다. 흰쥐 간의 조직학적 관찰은 $CCl_4$투여군은 정상군 및 olive oil 투여군에 비해 지방변화 및 간세포 내에 많은 대소의 cytoplasmic vacuole가 보였으나, $CCl_4$와 lectin을 동시 투여시는 $CCl_4$ 투여군에 비해 cytoplasmic vacuole은 현저히 감소하였고, 이에 비례하여 혈청 cholesterol 및 triglyceride 측정치가 현저히 감소하는 결과를 나타내었다. 이상의 결과를 볼때 흰쥐에서 lectin이 혈청 지질을 감소시키거나 또는 조직학적 관찰에서 간조직의 지질형성을 억제시키는 효과가 있는 것으로 확인되었다.
