Item Drug induced alterations in some rat hepatic microsomal components:a comparative study of four structurally different antimalarials(Pergamon Press, 1985) Thabrew, M.I.; Nashiru, T.O.; Emerole, G.O.Alterations in microsomal drug metabolizing enzymes, microsomal lipids and some serum enzymes following pre-treatment of rats with therapeutic doses of four structurally different antimalarial compounds, chloroquine (CQ), quinine (Q), quinacrine (QK) and primaquine (PQ) have been investigated. CQ and Q significantly decreased the activities of aminopyrene N-demethylase, aniline hydroxylase and both microsomal and cytosolic glutathione S-transferases. Only aniline hydroxylase was markedly decreased by QK, while PQ did not have much effect on any of these enzymes. CQ, Q and QK significantly increased the cholesterol:phospholipid ratio while all four compounds decreased the phosphatidyl choline:sphingomyelin (PC/S) ratio. All the drugs increased the activities of the serum enzymes glutamate-oxaloacetate transaminase, glutamate-pyruvate transaminase and alkaline phosphatase. The possible relationships of these results to structural variations in the four drugs being investigated has been discussed
