Values are means ± S.E of 8 rats. Mean values with^## mark are significant at P < 0.001 level (by one-way ANOVA). Comparisons were made between normal and high vitamin A-fed groups of each phenotype (AI-Lean: 2.6 mg vitamin A/kg diet, AII-Lean: 129 mg vitamin A/kg diet, BI-Obese: 2.6 mg vitamin A/kg diet and BII-Obese: 129 mg vitamin A/kg diet)
