Abstract
The current study was constructed to evaluate the efficacy of grape seed extracts (GSE) in management of obesity induced by high fat diet (HFD)-induced obesity in rats through assessment of the serum leptin, adiponectin, and resistin. Experimental rats were divided into three groups: G:1 (healthy control), G:2 (obese control), G:3 (received100 mg/kg of GSE), after 7 weeks, serum leptin, adiponectin, and resistin levels were measured in all groups.
Results in present study showed a significant (P<0.01) increase of serum leptin, and resistin levels in obese rats G2 in comparison to the control healthy rats G1 (39.35±1.07 vs 7.48±0.6), (48.84±3.73 vs 31.43 ± 2.02) respectively. The level of serum leptin, and resistin in obese rats decreased significantly in G3 (P < 0.01) when received GSE 100 mg/kg body weight for 7 weeks in regard to G2 (30.46 ± 0.93 vs 39.35 ± 1.07), (42.23±1.21vs48.84±3.73), whereas significant decrease in serum adiponectin level in obese rats G2 to G1 (4.8793 ± 0.5040 vs 9.245± 0.8794). After treatment with 100 mg/kg GSE, the level of adiponectin decresed in G3 compared with G2 (6.1220 ±0.6330 vs 4.8793± 0.5040).
Conclusions: The results show that, the phenolic extracts of grape seed could reduce serum leptin, and resistin levels and increase adiponectin in HFD induced obesity in rats.
