| dc.description | The objective of this work was to evaluate the overall myenteric neurons population from the duodenum of adult streptozotocin-induced diabetic rats supplemented with ascorbic acid (AA), a potent antioxidant. Fifteen 90-day-old rats were divided in groups: control (C), diabetic (D), diabetic treated with ascorbic acid (DA). After 120 days of experimental period duodenums were resected and processed as whole-mount preparations according to Giemsa's technique, which allowed us to evaluate neuronal density in an area of 8.96 mm² and measure the area of 500 neuronal cell bodies per group. It was observed a 32.55% reduction in neuronal density of group D when compared to group C (p<0.05). The density of spared neurons in group DA, in relation to group D, was not statistically different in this experimental model. No significant differences were found in neuronal areas when groups C and D or group D and DA were compared (p>0.05). These results lead us to conclude that the density of overall myenteric neurons population from the duodenum was reduced in diabetic rats (D), when compared to its control (C); and that diabetic rats supplemented with AA (DA) did not have their neuronal density preserved when compared to diabetic animals (D). | |
