INS and Insulin resistance: As seen from Table 1, levels of plasma insulin and insulin resistance index, but not plasma glucose, in fructose-drinking insulin resistance rats were significantly higher than those in control rats (34.6±4.5 mU/L, 8.52±0.62 in fructose-drinking insulin resistance rats and 14.5±2.9 mU/L, 3.30±0.34 in control rats, respectively, P<0.01).
