Última MORPHOMETRY AND QUANTIFICATION OF THE MYENTERIC NEURONS OF THE DUODENUM OF ADULT RATS FED WITH HYPOPROTEIC CHOW International Journal of Morphology Marçal Natali,Maria Raquel; Hubner de Miranda-Neto,Marcílio; Orsi,Antônio Marcos. Morphometric and quantitative analyses were carried out on the myenteric neurons of the duodenum, to study possible alterations resulting from a supply of low-protein level chow to adult Wistar rats. The animals were divided in two groups: nourished (N) fed with ration containing 22% protein for 210 days and the undernourished (D) fed with ration containing 8% protein from the 90th day of age on and during the next 120 days. Whole-mounts were stainedby the method of Giemsa and the histochemical reaction of NADH-diaphorase enzyme, to estimate the neuronal population, which revealed a greater neuronal density in undernourished rats, regardless of the technique employed. The morphometric studies of the cell body profiles of 500 neurons of each group indicated...

Alterations in the gastrointestinal neuromuscular function related to age have been demonstrated in human and animal models. This study analyzes the effects of the aging process on the area of the neuronal cell bodies of the myenteric plexus in the antimesenteric and intermediate regions of the ileal circumference of Wistar, 12 month-old in comparison 3 month-old animals. The ileum was removed and whole-mount preparations immunostained by the antibody anti-myosin-V were processed. The morphometric analyses were performed using a computerized image analysis system, with a subsequent distribution of neurons by size in intervals of 100 μm². The cellular body morphometry revealed a significant increase in the size of the myosin-V- immunoreactive...
