Effects of Gryllus bimaculatus powder on glucose (glucose tolerance test; GTT) and insulin tolerance (insulin tolerance test; ITT) states. Eight‐week‐old rats were injected intraperitoneally with a single dose of freshly prepared STZ (65 mg/kg). The control group was injected with an equal volume of citrate buffer only. After confirming the diabetic condition, the control group was fed a high dose of the Gryllus bimaculatus powder (6.5 g/kg) and the diabetic group was fed varying doses of the powder (1.63, 3.25, and 6.5 g/kg) twice daily. The GTT (a) and ITT (b) were performed as described in the Materials and Methods. Values are means ± SEM. n = 8; ^# p < .05 versus control groups; *p < .05 versus the STZ group
