1 Microphotometric analysis of cytochrome P-450 in periportal, midzonal, and perivenular hepatocytes of mice treated with phenobarbital. Phenobarbital cytochrome P450, family 21, subfamily a, polypeptide 1 Mus musculus
2 To obtain detailed information on the increase of cytochrome P-450 (P-450) content in periportal, midzonal, and perivenular hepatocytes after phenobarbital (PB) administration, and to study the mechanism of increased P-450 in the endoplasmic reticulum (ER), we estimated microphotometrically the P-450 content and morphometrically the area of ER in hepatocytes of three zones from mice injected with 35, 50, 100, or 150 mg/kg of PB for 3 days. Phenobarbital cytochrome P450, family 21, subfamily a, polypeptide 1 Mus musculus
