Abstract

The behavior of glycogen and histological changes of hepatic tissues in the liver of rats, aged 6 to 7 weeks, fed 18% casein diet under control, gramoxone and gramoxone + vitamin C(Vt. C) diets has been investigated in a comined histropathological and histochemical studies. Cloudy swelling and fat changes of hepatic cells were observed in the gramoxone group with the duration of feeding time. Fat changes of hepatic cells were observed more obviously than cloudy welling, especially in the hepatic cells of periportal area. The number of Kupffer's cells increased signifciantly in the gramoxone group fed for 4weeks. The cloudy swelling and fat changes decreased obviously in the gramxone + Vt. C group. Glycogen content of heaptic cells tended to increase slightly in the gramoxone group as compared with the control group . moreover, glycogen depositons were higher in the hepatic cells where fat changes were obvious. It seems to be that Vt.C alleviating effects on the gramoxone toxicity in the patterns of glycogen distribution and histological structure of heaptic tissues.

흰쥐의 간조직에 미치는 gramoxone 독성과 비타민 C의 완화효과에 대해 조사하였다. Gramoxone처리군에서 간세포의 혼탁종창과 지방변화가 사육기간이 증가함에 따라 현저하고 혼탁종창보다는 지방변화가 더 현저하였으며, 특히 간소엽의 문맥야주변대 간세포에서 지방변화가 심하였다. Kupffer세포의 수도 증가하여 4주 사육군에서 제일 많이 증가하였다. Gramoxone-비타민 C 처리군에서 간세포의 혼탁종창과 지방변화가 현저히 감소하였다. 간세포의 glycogen 함량은 정상대조군에 비해 gramoxone처리군에서 다소 증가하는 경향을 나타내었으며 특히 지방변화가 많이 일어난 간세포에서 glycogen 함량이 더 많았다. Gramoxone-비타민 C 처리군에서 gramoxone처리군에 비해 간세포의 glycogen 함량이 감소하는 경향을 나타내었다.
