Number of ethidium bromide-positive nuclei. Histogram showing the ethidium bromide-positive nuclei along the mesenteric arterioles of rats that were untreated diabetics (DM), diabetics treated with low curcumin (DM+cur30), diabetics treated with high curcumin (DM+cur300), controls (con) or controls treated with curcumin (con+cur300) rats. Data are expressed as mean ± SEM (n = 5 for each group). NS, no significant difference compared to control arterioles; **P < 0.01 and *P < 0.05, significant difference compared to control arterioles; †† P < 0.01, significant difference compared to diabetic arterioles.
