All values expressed as means ± s.e.m. (n = 4 animals). One-way ANOVA was used in comparison of the control and the two groups made diabetic from age 7 weeks (the group spared captopril treatment and the group treated with captopril) followed by Tukey's Honestly Significant Difference test for pair-wise multiple comparisons. A value of P <0.05 was considered statistically significant.
Significantly different from the control group.
Significantly different from the similarly diabetic group spared captopril treatment. The body weight-normalized values were calculated using the corresponding body weight of the anaesthetised rat.
