to study the mechanism for the adaptive mucosal hyperplasia which occurs independent of luminal nutrition and pancreatico-biliary secretions in isolated thiry-vella segments of intestine from lactating rats , and to examine the effects of prolactin on small bowel mucosal structure in the rat , we used two models of experimental hyperprolactinaemia and compared quantitative histology and several markers of mucosal mass in jejunum and ileum from control rats and from test and lactating animals .
