  • Title: The effects of aminoethyl phosphonic acid on hepatic microsomal drug metabolism and ultrastructure of normal and cholesterol fed rats.

    Journal: J Nutr; 1978 Aug; 108(8):1234-43. PubMed ID: 671091.
    Abstract:
    The effects of parenteral administration of aminoethyl phosphonic acid (AEP) on the liver microsomal drug metabolism and ultrastructure were studied in normal and 1% cholesterol-fed albino rats. AEP administration to rats fed a stock-diet resulted in decreased demethylation of aminopyrine with a concomitant fall in cytochrome P-450 level. Aniline hydroxylation remained unaltered. AEP injection to cholesterol-fed rats, caused marked reduction in both aminopyrine demethylation and aniline hydroxylation, with a significant increase in cytochrome P-450 level. AEP injection to both control and cholesterol-fed animals produced a modest increase in Bilirubin UDP-glucuronyl transferase. RNA:DNA ratio showed remarkable elevation in rats fed the cholesterol diet with AEP injection. AEP injection caused an atypical smooth endoplasmic reticulum and a marked loss of nuclear euchromatin. Effect of AEP was more pronounced in rats receiving the cholesterol-diet. AEP administration thus induces structural and drug metabolic enzyme alteration in liver.
