Intestinal tissue morphology and the distribution of ghrelin in the intestine of Saurogobio dumerili
摘要
Abstract
The intestinal structure and the distribution of ghrelin in intestinal tissue of Saurogobio dumerili were studied by hematoxylin and eosin (HE) and immunohistochemistry respectively. Histological studies showed that the intestinal tissue of Saurogobio dumerili was composed by the mucosa, submucosa, muscularis and serosa layer from the inner to the outside. The thickness of mucosa and the lenghth of intestinal villi in midintestine were significantly thicker and longer than that in foreintestine and in hindintestine (P<0.05) .The thickness of submucosa, muscularis and serosa layer in foreintestine and midintestine was significantly thicker than that in hindintestine (P<0.05), although there were no significant difference between in foreintestine and in hindintestine (P>0.05). Immunohistochemical results showed that there were no ghrelin positive immunostaining in mucosa of each intestinal sections. In submucosa, muscularis and serosa layer, the ghrelin positive immunoreactions were found, and the strongest immunoreactions were seen in submucosa of foreintestine, weaker in midintestine, and the weakest in hindintestine; Compared to submucosa, the positive immunostaining of ghrelin in muscularis and serosa layer was weaker. According to the difference in the intestinal histological structure, the intestinal tract of Saurogobio dumerili was divided into foregut, midgut, and hindgut. The distribution of ghrelin in the intestinal tract showed that ghrelin plays an important role in the endocrine regulation of ingestion, digestion and absorption of food.关键词
