Abstract: Objective To investigate the effect of high-fat or high-glucose diet on obesity and visceral adipose tissue in C57BL/6 mice. Methods Four-week-old C57BL/6 mice were allocated into normal diet group,high-fat diet group,and high-glucose diet group according to the random number table until 20 weeks old. Body weight,epididymal adipose tissue weight,blood leptin,fat infiltration in liver,M1/M2 macrophage subtypes,and monocyte chemoattractant protein-1 mRNA in epididymal adipose tissues were measured. Results Compared with normal diet group,body weight,epididymal adipose tissue weight,and leptin concentration in high fat diet group at 20 weeks were significantly increased(P<0.05),and oil red O staining showed more prominent adipocyte infiltration in liver in high-fat diet group than those in normal diet and high-glucose diet group. However,no apparent differences were seen in high-glucose diet group at 20 weeks in terms of body weight,epididymal adipose tissue weight and leptin concentration. In high-fat diet group,the macrophages infiltration in epididymal adipose tissue increased with time and the percentage of M2 macrophage decreased in high-fat diet group than that in high-glucose diet group(P<0.05). Compared with normal diet group,monocyte chemoattractant protein-1 mRNA expression increased significantly in high-fat diet group(P<0.05). In high-glucose group,however,no significant differences were discerned(P>0.05).Conclusion High-fat diet,rather than 60% high glucose diet,will lead to obesity and macrophage infiltration in adipose tissues.

Key words: adipose tissue, high-fat diet, high-glucose diet, macrophages, obesity
