The effects of electroacupuncture (EA) on pro-/anti-inflammatory cytokines and blood glucose (BG) in lean and obese Long Evans rats were investigated. Group 1 and Group 3 had five lean and seven obese rats, respectively, and received EA at the Zhongwan/Guanyuan acupoints on Day 1, Day 3, Day 5, Day 8, Day 10, and Day 12. Group 2 and Group 4, with five lean and seven obese rats, respectively, did not undergo EA. After induction of anesthesia, BG was measured at 10 minutes and 20 minutes. EA was applied for 30 minutes, and BG was measured again. At the end of the study, blood and white adipose tissue were collected. Analyses showed that for all groups, the mean BG at 20 minutes (baseline) and 50 minutes were significantly greater on Day 1 than on any other day. Compared with Group 2, the baseline BG in Week 1 for Group 1 was significantly lower, but Groups 3 and 4 showed no difference. Group 1 had significantly higher serum interleukin-10 and tumor necrosis factor-α than Group 2, while Group 3's serum leptin was greater than Group 4's. White adipose tissue interleukin-10 and adiponectin:leptin ratio were higher for Group 1 than Group 2. EA affected no significant differences in any other components measured for lean and obese animals.
