The comparisons of biochemistry between OP and OR rats The differences between OP and OR rats included not only body weight, but lipids metabolism and insulin sensitivity as well, characterized with insulin resistance, increasing in serum free fatty acids and ketone body, and hepatic TC and TG in OP rats. However, no significant differences were observed in serum TG, TC, LDL, HDL and fasting glucose between OP and OR rats.⑶Comparisons of metabolites in serum, urine and liver tissue between OP and OR rats①There were significant differences in amino acids concentration between OP and OR rats,especially in liver tissue, such as high concentrations in ketogenic and glucogenic amino acids in OP rats, suggesting differences in amino acids metabolism;② The different metabolites between OP and OR rats included increasing of various saturated fatty acids and decreasing of polyunsaturated fatty acids in OP rats;③The urinary metabolites analysis indicated that different structure or metabolism of gut microflora might exist between the two phenotypes, which probably influenced the regulation of body weight gain;④The end-products of catecholamines in urine and intermediates of krebs cycle in serum in OP rats were all up-regulated, suggesting that the activity of sympatheic nervous system and energy metabolism was higher in OP rats than OR rats.

胰岛素耐受实验和胰岛素敏感指数表明OP动物的胰岛素敏感性较OR动物下降，而OP大鼠血清中游离脂肪酸、酮体、肝脏总胆固醇和甘油三酯水平显著升高；但是，OP与OR大鼠血清中总胆固醇、甘油三酯、低密度脂蛋白、高密度脂蛋白和空腹血糖等的水平并无显著性差异；⑶肥胖易感与肥胖抵抗大鼠血清、尿液和肝脏组织提取物中代谢物的比较研究表明：①OP与OR大鼠的血清、尿液和肝组织提取物中多种氨基酸的含量存在显著差异，并以肝组织中的差异氨基酸数量为最多，包括各种生酮和生糖氨基酸水平在OP组的升高，说明氨基酸代谢的差异是两种体重表型大鼠之间存在的重要差异特征之一；②OP与OR动物肝脏和血清差异代谢物中包含多种饱和长链脂肪酸的升高如十四烷酸、十六烷酸、硬脂酸等和多不饱和脂肪酸的下降如亚油酸和花生四烯酸，说明两种体重表型动物的肝脏脂肪酸代谢存在明显差异；③长期高脂饮食喂养后，动物的尿液代谢物分析表明OP与OR动物体内的肠道菌群结构存在差异，这些菌群上的差别可能在动物体重增长的调节上产生影响；④与OR动物相比，OP动物尿液代谢物中儿茶酚胺类递质的代谢终产物如高香草酸、扁桃酸和4-羟基苯乙酸明显升高。
