Effect of 6-week treatment with Allium fistulosum aqueous extract (AFW) and A. fistulosum ethanolic extract (AFE) on adipocyte size in epididymal adipose tissue of high-fat diet (HFD)-induced obese mice. a Representative photographs of adipose tissue of hematoxylin and eosin-stained tissue sections (magnification, 400×). b Adipocyte area of hematoxylin and eosin-stained adipose tissue sections. Normal, standard chow; HFD-control, HFD only; HFD-HCA, HFD plus 100 mg/kg Garcinia cambogia extract containing hydroxycitric acid; HFD-CLA, HFD plus 100 mg/kg conjugated linoleic acid; HFD-ORL, HFD plus 15.6 mg/kg Xenical (orlistat); HFD-AFW, HFD plus 100 mg/kg AFW; HFD-AFE, HFD plus 100 mg/kg AFE. Results are expressed as the mean ± standard error of the mean (SEM) (n = 6). # p < 0.05 compared with the normal control group; * p < 0.05, ** p < 0.01 compared with the HFD-control group
