Morphological and Quantitative Analyses of the NADH-d Myenteric Neurons of the Jejunum of Rats Submitted to Experimental Chronic Alcoholism

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 (...

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).
