| Abstract: We investigated the effects of acetylsalicylic acid (ASA) on the total myenteric neuronal population in the descending colon in Trypanosoma cruzi-infected mice. Thirty-five male Swiss mice, 60 days old, were divided into a control group (C group), control group treated with ASA (CA group), infected group (I group), and infected group treated with ASA (IA group). A total of 1300 trypomastigotes of the Y strain of T. cruzi were intraperitoneally inoculated in the IA and I groups. The CA and IA groups were treated with ASA intraperitoneally. At 75 days post-infection (dpi), all of the animals were sacrificed. Neurons in the colon were stained with Giemsa, quantified, and measured. No difference in the course of infection was observed between the IA... |

| The effects of food restriction (FR) on the morphoquantitative aspects of the wall and myenteric neurons of the proximal colon in adult rats were analysed. FR was imposed by duplication of the experimental brood size in relation to the control brood during lactation. The FR group received a 50% reduction of food from weaning until 90 days of age. Samples of the colon underwent histological processing to morphometrically analyze the crypts, muscularis mucosae, tunica mucosa, and muscularis externa. We determined the number of goblet cells and serotoninergic enteroendocrine cells, and morphoquantitatively studied the myenteric neuronal population. FR caused hypertrophy in the tunica mucosa, increase in crypt depth and in the muscular layer of the mucosa, a... |

| The objective of our work was to verify, during an experimental period of 210 days, the possible effects of the ethanol on the morphology and density of the NADH-diaforase myenteric neurons in the jejunum of alcoholic rats. We used 10 animals (Rattus norvegicus) separated in 2 groups: the controls (n=5), that received a normal proteic diet (22%) and water ad libitum; the alcoholic, that received NUVILAB normal proteic chow (22%) and sugar cane brandy diluted at 30 Gay Lussac (30 v/v). The jejunum segment was collected and submitted to the histochemical technique to stain the nervous cells and, then, to the elaboration of membrane whole mounts. The observation through light microscopy showed that there are no expressive morphologic differences between the... |

| Morphometric and quantitative analyses were accomplished to study the effects of the consumption of alcohol above the size and density of the myenteric neurons of cecum of rats. Ten rats with 90 days were divided in the groups: control (C), and alcoholic (A). After 120 days of treatment with ethanol the cecum of both groups were collected, submitted it prepared of membranes that after carried out to Giemsa´s technique, permitted to evaluate the neuronal density, in an area of 13.44mm², and measure the cell body area of 300 neurons by group. The alcoholic rats presented an increase in the number of small neurons and a reduction of the big and medium neurons. The neuronal density verified in alcoholic rats was significantly reduced regarding the controls... |
