Values are shown as mean ± SEM with the number of animal from which kidneys were taken, shown in brackets.
P < 0.05 significantly different from WKY,
P < 0.05, significantly different from untreated SHR; one-way anova, followed by a Bonferroni post hoc test, three multiple comparisons.
SBP, systolic blood pressure; HbNO, iron nitroxyl-haemoglobin.
