Influence of acupuncture combined with traditional Chinese medicine on serum leptin level and hypothalamic leptin receptor expression in simple obesity rats / 国际中医中药杂志

ABSTRACT

Objective To observe the effect of acupuncture combined with traditional Chinese medicine on serum leptin contents and the expression of leptin receptor in the hypothalamus in simple obesity rats so as to explore the underlying mechanism. Methods A total of 120 male Wistar rats were randomly divided into normal control group and high grease group, which was established by fed with high fat forage for 16 weeks. 60 successful rat models were divided into shilianyin+electro-acupuncture group, fatness model group, and control group with random digits table. Electro-acupuncture was applied to Zusanli and Zhongwan, and Shilian-yin 22.4 g/kg was administered, once daily, for 14 days in the shilianyin + electro-acupuncture group; Fatness model group was lavaged with isotonic Na chloride 2 ml/kg; while the control group was lavaged with sibutramine 1.6 mg/kg. The body weight, body length and Lee's index were measured once every 10 days. Serum leptin contents were measured by radioimmunoassay, and leptin receptor expression was detected with immunohistochemistry. Results In comparison with fatness model group (13.401 ± 6.138) ng/ml, the serum leptin content of shilianyin+electro-acupuncture group decreased significantly (9.467+ 3.587) ng/ml (P<0.01) , and the number of leptin receptor expression increased considerably (leptin-acceptor masculine cell was 52.30±21.35piece/mm2) (P<0.01). Conclusion The benign regulation of acupuncture combined with traditional Chinese medicine on hypothalamus and serum leptin of obesity body is a significant joint of improving leptin-counteract and abnormal internal hormone metabolism.
