| Abstract: | The present paper reports the modulatory influence of two widely used combined oral contraceptive pills "OVRAL" and "NORACYCLINE" on hepatic phase I and II drug metabolizing enzymes and acid soluble sulfhydryl group of the mouse. Three different doses of the pills were used in this study i.e. D1 (1/2000th of a pill), D2 (1/200th of a pill) and D3 (1/20th of a pill). The sulfhydryl group increased significantly with the D1 and D2 dose of Ovral and the D2 dose of Noracycline. Dose D2 of both pills decreased cyt.P450 and cyt.b5 contents. D3 of Noracycline, however increased both the cytochrome levels. Dose D3 of Ovral and all three doses of Noracycline reduced the glutathione S-transferase activity. |
