Résumé

Dietary intake of technical hexachlorocyclohexane (HCH) by albino mice for 2 weeks (at 400 and 800 ppm) resulted in hyperlipemia. Significant increase in triglycerides, phospholipids and cholesterol fractions of blood was observed in these animals. Dietary intake of gamma-isomer of HCH for 2 weeks (at 200 ppm) did not have any effect on blood lipid profile, but at 400 ppm level produced higher contents of phospholipids and cholesterol. The hepatomegaly produced by dietary technical HCH or gamma-HCH was not accompanied by fatty metamorphosis of liver. Hypertriglyceridemia caused by HCH was accompanied by lower triglyceride levels in liver, suggesting a possible higher rate of secretion from liver.

Résumé

Dietary hexachlorocyclohexane (HCH) and gamma-isomer of HCH produced significant increase in liver weights of mice. Elevated levels of alanine and aspartate aminotransferases and of alkaline phosphatase in the blood of these animals suggested hepatotoxicity. Hepatic soluble enzymes--aspartate aminotransferase and lactate dehydrogenase--were markedly lowered. Among the hepatic lysosomal enzymes, acid phosphatase and acid cathepsin were increased in the experimental animals. Hepatic glucose-6-phosphatase was lowered by HCH while aldolase activity was increased. Hydrolytic enzymes in small intestine, viz., disaccharidases, lipase, amylase, dipeptidase and phosphatases, were also affected by dietary HCH and gamma-HCH. The results suggested cellular toxicity in hepatocytes of HCH and gamma-HCH fed animals, and also interference in gastrointestinal absorption.

Résumé

Dietary intake of beta- and gamma-hexachlorocyclohexane (beta- and gamma-HCH) by albino rats for two weeks (at 800 ppm level) resulted in impairment of lipid metabolism, viz. hyperlipemia and fatty metamorphosis of liver. Liver fat content was increased by both beta- and gamma-HCH. Significant increases were observed in triglyceride and phospholipid fractions of blood in these experimental animals. The incorporation of [14C]acetate and palmitate into liver and blood lipids was higher in HCH pretreated animals, suggesting a higher rate of fat synthesis in liver and of secretion as well.
