Changes in blood glucose levels during the experiments. a Increases in blood glucose levels during preparations [Δglucose (preparations)]; there was no significant difference among the three groups (P > 0.05, 1-way ANOVA). b Increases in blood glucose levels during laparotomy [Δglucose (laparotomy)]; there was no significant difference among the three groups (P > 0.05, 1-way ANOVA). c Decreases in blood glucose levels during the insulin tolerance test [Δglucose (ITT)]; there was no significant difference among the three groups (P > 0.05, 1-way ANOVA)
