Effects of LC on the changes in body weights of STZ-treated mice. control: control group (n = 6), DM+NS: diabetic group (n = 4), pre-treatment: preventive group (n = 3), DM+LC (H): high-dose therapeutic group (n = 4), DM+LC (L): low-dose therapeutic group (n = 3). All values are expressed as the mean ± S.E. using the repeated measures method. *P < 0.05, **P < 0.01 (compared to control group), #P < 0.05, ##P < 0.01 (compared to diabetic group).
