Alcohol and its metabolites are responsible for damage both within the gastrointestinal tract and other organs. Alcohol abuse promote intestinal inflammation, that may be the cause of multiple organ dysfunctions and chronic disorders. In this research, the effect of astaxanthin, a powerful antioxidant with several biological effects, on alcohol damage-induced in the intestine of Carassius auratus, was investigated. In the fishes exposed to ethanol, an increase of the intestinal epithelium mucous cells and circulating macrophages, with intestinal mucosa disorganization was observed. In contrast, in the fishes treated with astaxanthin intestinal morphology was restored. By immunohistochemical analysis, using α-Smooth Muscle Actin (α-SMA) and Vasoactive intestinal polypeptide (VIP) antibodies, a reduction of inflammatory states alcohol-induced was evident, with more regular muscularis submucosa and more organized intestinal mucosa without inflammatory cells.

Abstract

Alcohol and its metabolites are responsible for damage both within the gastrointestinal tract and other organs. Alcohol abuse promote intestinal inflammation, that may be the cause of multiple organ dysfunctions and chronic disorders. In this research, the effect of astaxanthin, a powerful antioxidant with several biological effects, on alcohol damage-induced in the intestine of Carassius auratus, was investigated. In the fishes exposed to ethanol, an increase of the intestinal epithelium mucous cells and circulating macrophages, with intestinal mucosa disorganization was observed. In contrast, in the fishes treated with astaxanthin intestinal morphology was restored. By immunohistochemical analysis, using α-Smooth Muscle Actin (α-SMA) and Vasoactive intestinal polypeptide (VIP) antibodies, a reduction of inflammatory states alcohol-induced was evident, with more regular muscularis submucosa and more organized intestinal mucosa without inflammatory cells. The results suggest that astaxanthin treatments can be a good candidate for preventing damage within the gastrointestinal associated with excessive alcohol consumption.
