Fasted, male, obese, Zucker, diabetic fatty rats aged 10?16 weeks were anesthetized with 1% halothane in nitrous oxide?oxygen (3:1) on alternate weekdays over 2 weeks. Group 1 (n = 4) did not receive electroacupuncture (controls); Group 2 (n = 4) received electroacupuncture using the Zhongwan and the Guanyuan acupoints; Group 3 (n = 4) received electroacupuncture using the bilateral Zusanli acupoints; Group 4 (n = 6) received neither halothane in nitrous oxide:oxygen nor electroacupuncture. At the end of study, animals were injected with sodium pentobarbitone (60 mg/mL, i.p.), and blood and white adipose tissue were collected. Analysis of variance and Duncan's tests showed that the mean leptin in serum was significantly lower and the adiponectin:leptin ratio was significantly higher in Group 2 than in Group 1 (p < 0.05); for Group 4, the serum leptin was significantly higher than it was for Groups 1?3 (p < 0.05), and the adiponectin:leptin ratio was significantly lower than it was for Group 2 (p < 0.05). Similar changes occurred for the leptin levels in the pelvic adipose tissue. In addition, for Group 2, the mean serum insulin: glucose ratio was significantly higher than it was for Group 1 (p < 0.05); for Group 4 the mean serum insulin and insulin: glucose ratio were significantly higher than they were for Groups 1 and 3 (p < 0.05), but not Group 2 (p > 0.05). No significant differences in the serum or the adipose-tissue measurements between Groups 1 and 3 were observed (p > 0.05).
