Overall number of ganglion cells in the myenteric plexus between longitudinal and circular muscle layer of adult colon was 16.31 [+ or -] 3.81 ganglion cells/[mm.sup.up.2] and 8.86 [+ or -] 1.79 ganglion cells/[mm.sup.up.2] in its rectum.
(13,14) In the literature, a study reported that the rate of achalasia was elevated among patients with BN compared to the general population, (7) and there are some case reports about BN patients developing achalasia because of myenteric plexus damage.
Summing up, it could be said that the quercetin supplementation in diabetic animals promotes a set of metabolic changes that lead to an increase of weight loss and a slight reduction in blood glucose, whereas the NADHd neurons in the myenteric plexus of the ileum maintains the nucleus and cytoplasm volume and reduces neuronal loss.
Moreover, the highest level of HO1 and HO2 expression in the tissue homogenates of the control duodenum (including the smooth muscle layers of the gut wall and the myenteric plexus between them) also highlights an intensified protective environment in this particular gut segment and emphasizes the importance of the neuronal microenvironment [10, 12].
This phenomenon could well be related to the degeneration of autonomic neurons in the myenteric plexus and brainstem [45].
The longitudinal muscle strip with the myenteric plexus attached was separated from the underlying circular muscle according to the method of Paton and Vizi [29].
Control group (Figures 5(a) and 6(a)) shows the dense c-Kit-positive cellular network (ICC-DMP), located between the longitudinal and circular muscularis and at the innermost part of the circular muscularis, and intermingled with the myenteric plexus. Between the circular muscle fibers, there was abundance of VAChT/nNOS-positive nerve fibers and c-Kit-positive cellular network run parallel with the muscle fibers.
