Resumen: | We examined the effects of ascorbic acid supplementation on myosin-V, calcitonin gene-related peptide (CGRP) and vasoactive intestinal polypeptide (VIP) immunoractivities in the myenteric neurons in aging rats. Male rats were divided into groups: young 90-day-old rats (E90), 345-day-old control rats (E345), 428-day-old control rats (E428), 90- to 345-day-old rats treated with ascorbic acid (1 g/L) (EA345), and 90- to 428-day-old rats treated with ascorbic acid (1g/L) (EA428). The quantitative results showed that aging reduced the number of myosin-V-immunoreactive neurons compared with young animals (E90). Ascorbic acid supplementation in the EA345 and EA428 groups increased the average area of myosin-V neurons by 24.6% and 24.1% compared with the E345 and E428 groups, respectively. When all groups were compared, we observed significant differences for the CGRP- and VIP-immunoractive varicosities of nerve fibers from myenteric neurons. Ascorbic acid supplementation had a neurotrophic effect on all neurons studied, suggesting a neuroprotective role |
