title: [Proliferation of the intestinal epithelium and of the regenerating liver with a deficiency of the epidermal growth factor].
abstract: To determine the role of the epidermal growth factor (EGF) in the regenerative stimulation of intestinal epithelium and hepatocyte proliferation after partial resection of these organs the labeling index of the intestine and liver in sialadenectomized rats was studied. EGF concentration in the saliva and serum was determined using radioimmunoassay. The decrease in EGF concentration after the removal of submandibular salivary glands was shown to slower hepatocytes entering the mitotic cycle and to inhibit the activity of enterocyte proliferation in the small intestine. The data show pronounced in vivo mitogenic effect of EGF on the liver and intestinal epithelium.
