Effects of imidacloprid on body weight, body weight gain, adipocyte size, and food intake. Mice were fed with low or high fat diet supplemented with imidacloprid (0, 0.06, 0.6, and 6 mg/kg bw/day) for 12 weeks. (A) Body weight was monitored weekly. (B) Body weight gain over 12 weeks. (C) Total calorie intake. (D) Representative pictures of epididymal adipose tissues after H&E staining (100× magnifications). (E) Adipocyte size. The mean area of 50 cells from each sample was measured with Image J. Numbers are means ± SE (n = 5–7 for A, B, and D and n = 3–4 for E). Means with different letters are significantly different at P < 0.05.
