ABSTRACT
Objective To assay the serum adiponectin levels in normal subjects and patients with insulin resistance syndrome, and to explore the correlation between adiponectin and insulin sensitivity, blood glucose, insulin, lipids etc. Methods Insulin sensitivity index (SI) was assessed by the reduced sample number of Bergman's minimal model method with intravenous glucose tolerance test in subjects of normal controls, obesity, impaired glucose tolerance (ICT) and type 2 diabetes mellitus (DM). Meanwhile the anthropometrical parameters such as body mass index (BMI) and waist hip ratio (WHR) were evaluated and the serum lipids, fasting and postprandial 2 h plasma glucose and insulin levels were also measured. Results Compared with normal control group, the SI in obesity, IGT and type 2 DM groups was significantly decreased (P
