Effect of 6-week treatment with Allium fistulosum aqueous extract (AFW) and A. fistulosum ethanolic extract (AFE) on serum adipocytokine and IGF-1 concentrations in high-fat diet (HFD)-induced obese mice, as assessed by enzyme-linked immunosorbent assay. Serum levels of (a) leptin, (b) adiponectin, and (c) IGF-1. Results are expressed as the mean ± standard error of the mean (SEM) (n = 6). 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. ### p < 0.001 compared with the normal control group; * p < 0.05, ** p < 0.01, *** p < 0.001 compared with the HFD-control group
