ABSTRACT
Objective To observe the effects of Chinese medicinal herbs with the efficacy of invigorating spleen, upbearing the clear, and tonifying spleen on the obesity degree, fat hormones, and insulin resistance in diet-induced obesity (DIO) rats;To choose better anti-obesity herbs from different Chinese medicinal herbs that can tonify spleen. Methods Among the 130 Wistar rats, 10 were chosen as the blank control group (fed with basal forage), and the remaining 120 were administered with high-fat high-nutrition forage for 13 weeks. According to weight, 50 DIO rats and 10 diet-induced obesity resistance (DIO-R) rats were obtained. DIO rats were divided into model group (normal saline), sibutramine group, invigorating spleen group (Atractylodix Rhizome and Magnoliae Officinalis Cortex), upbearing the clear group (Bupleuri Radix and Aurantii Fructus Immaturus) and medicine for tonifying qi and spleen group (Astragali Radix). All groups received gavage with corresponding drugs. Rats in the blank control group and the DIO-R group received gavage with normal saline. The basal forage was administered to rats in the blank control group, while high-fat forage was continually given to rats in the other six groups. Insulin resistance index (IRI), blood glucose, triglycerides, cholesterol, tumor necrosis factor α (TNF-α) and adiponectin were detected after blood withdrawing. TNF-α and adiponectin in the fat homogenate were examined. Results Compared with the blank control group, body weight, IRI, and cholesterol of rats in the model group significantly increased (P<0.01);adiponectin in homogenate reduced (P<0.01);serum and adipose homogenate TNF-α increased (P<0.01). Compared with model group, body weight, IRI, cholesterol of rats in DIO-R group significantly decreased (P<0.01);adiponectin in fat homogenate increased (P<0.01). Body weight and cholesterol of rats in the sibutramine group significantly decreased (P<0.01), while serum and adipose homogenates TNF-αdecreased (P<0.05, P<0.01). Body weight, IRI and cholesterol of rats in upbearing the clear group decreased (P<0.05, P<0.01);serum and adipose homogenate TNF-α decreased (P<0.05, P<0.01);adiponectin increased in fat homogenate (P<0.05). IRI, cholesterol and serum TNF-αof rats in the invigorating spleen group decreased (P<0.05, P<0.01);adiponectin in serum and adipose homogenate increased (P<0.05). BMI, blood glucose, IRI and cholesterol of rats in Astragali Radix group decreased (P<0.05, P<0.01);TNF-α decreased and adiponectin increased in serum and adipose homogenate (P<0.05, P<0.01). Conclusion Astragali Radix could reduce obesity induced by high-fat forage, and its effects on improving glucose and lipid metabolism disorder and IR are better than the other TCM groups. Its mechanism is related to decreasing TNF-α and increasing adiponectin level.
