Effects of retinoic acid (0.1 mg/kg body weight) and vitamin E (2.0 mg/kg body weight) supplementation on hepatocyte proliferation in rats fed with ethanol for a one-month period. Hepatocytes in S-phase were determined by immunohistochemical staining for proliferating cell nuclear antigen (PCNA) in liver sections. A total of 20 fields were screened per animal and examined under light microscopy. C, control; Alc, ethanol; RA, retinoic acid; VE, vitamin E. Treatments not sharing the same superscript are significantly different from each other (P<0.05).
