Sorbitol levels are expressed as μg/mL RBC. Sorbitol levels were measured in RBC incubated in the presence of normal (5.5 mM) and high (55 mM) glucose for 3 h. indicates a statistically significant difference from the control group and indicates a statistically significant difference from the glucose 55 mM group ( ). Values are mean ± standard deviation of three independent experiments.
