Abstract

This paper deals with the effects of proteic desnutrition on the morphology, morphometry and density of the neurons of the myenteric plexus. The ileum of 10 rats was used. For this study five rats aging 90 days were fed during 120 days with hypoproteic ration (experimental group) and five rats (control group) received ration with normal proteic level. Segments of the ileum were obtained for the method of whole-mount preparation, stained with Giemsa (Barbosa, 1978) and for histological routine treatment stained with HE. The neurons were clustered in ganglia located between the circular and longitudinal layers of the muscular tunica. Based on the lengths of the major longitudinal and transverse axes, the neurons were selected in three groups: small, medium and large. The neuronal density on the ileum of rats corresponding to an area of 7.08mm2 was 1,482 and 2,515 neurons on the control and experimental groups respectively. The data suggested that proteic desnutrition did not cause alteration to the neuronal density.
