Effect of Di-(2-ethylhexyl) phthalate (DEHP) on chemical constituents and enzymatic activity of rat liver. 1978

S P Srivastava, and D K Agarwal, and M Mushtaq, and P K Seth

Effect of Di(2-ethylhexyl) phthalate (DEHP), was investigated on chemical constituents and activity of certain enzymes of rat liver. A significant increase in liver weight; total and relative to body weight; decrease in total, free and esterified cholesterol; and no change in dry weight, moisture; RNA, DNA, total lipids, phospholipids, pyruvic acid and lactic acid contents was observed in liver of DEHP-treated rats as compared to controls. Activity of 3 mitochondrial enzymes, malic dehydrogenase, cytochrome-c-oxidase and diaphorase were significantly decreased while that of NADH-cytochrome c reductase, RNAase and DNAase remained unaltered upon treatment. The results suggest that DEHP exerts its hepatotoxic effects by interfering with bioenergetics of the cell.
