The effects of quercetin supplementation in NADH-diaphorase positive (NADH-d) neurons of streptozotocin-induced diabetic rats was carried in this study.
Fifteen male rats were divided into three groups:
normoglycemic (N), diabetic (D) and diabetic supplemented with quercetin (DQ). Whole mount preparations of the muscular layer of the ileum underwent NADH-d histochemistry for evidencing the NADH-d neuronal subpopulation. Quantitative analyzes were performed on 30 random fields, and morphometric analyzes in 100 neuronal bodies and nuclei per animal. The supplementation promoted a 44 % reduction in the neuronal density in D group when compared to N group (p <0.001); a 24.5 % reduction was observed in the DQ group when compared to N (p <0.01). Animals in D group presented an 18.7 % increase in the cell body areas of myenteric neurons when compared to N (p <0.001); DQ group showed a 14.2 % decrease in neuronal areas when compared to D (p <0.01); the nuclear area were similar among the three groups. We conclude that quercetin supplementation was positive for animals with diabetes mellitus.
