INS and Insulin resistance: The serum insulin, leptin and adiponectin levels were measured using ELISA kits and the serum triglyceride, cholesterol and fasting glucose levels were measured by using Synchron cx5. The results showed that fasting glucose, insulin, homoeostasis model assessment for insulin resistance (HOMA-IR), triglyceride, cholesterol and leptin levels in the experimental group were all significantly higher than those in the control group (Table 3).
