MORPHOMETRY AND QUANTIFICATION OF THE MYENTERIC NEURONS OF THE DUODENUM OF ADULT RATS FED WITH HYPOPROTEIC CHOW
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...
