title: Basal induction of cytochrome P-450 1A1/1A2 in cells of the liver, small intestinal villi, and lymph nodes in rats.
abstract: Rat liver, small intestinal wall, mesenteric, mediastinal, and popliteal lymph nodes of rats were studied by indirect immunoperoxidase method with monoclonal antibodies to cytochrome P-450 1A1/1A2. These cytochrome forms were detected in low concentrations in hepatocytes, macrophages of the small intestinal villi and mesenteric and mediastinal lymph nodes of intact animals. Basal induction of monooxygenase enzymes can be caused by cytochrome inductors entering with air (environmental pollution) or food.
