Effect of EULE on serum NO and cGMP concentrations in STZ-induced diabetic rats. The concentrations of NO and cGMP were detected with test kits. (a) NO concentrations. (b) cGMP concentrations. The data are presented as the mean ± SEM. p < 0.01 versus the control group; # p < 0.05, ## p < 0.01, and ### p < 0.001 versus the DM group (n = 10 in each group).
