Cytochrome P-450 monooxygenases in the mosquito, Culex pipiens

Creator:: Baldridge, Gerald D.
Abstract:: A sucrose density-gradient ultracentrifugation technique for obtaining microsomes has been developed. This technique has advantages over the classic differential centrifugation technique, in that it is faster, is better suited to work with small quantities of tissue, and offers the opportunity to work with a defined microsomal sub-cellular fraction, rather than...

B-Naphthoflavone induction and its effect on hepatic phospholipid metabolism in rainbow trout (Salmo gairdneri)

Creator:: Harris, Marcia Elaine
Abstract:: The induction of drug-metabolizing enzymes is a complex biochemical process manifested not only by increases in various cytochrome P-450 isozymes and related activities, but also by alterations in endoplasmic reticulum membranes. Little work has been done to examine how cytochrome P-450 inducing agents influence other cellular processes, such as phospholipid...
