Ethynylestradiol-induced impairment of bile secretion in the rat: protective effects of S-adenosyl-L-methionine and its implication in estrogen metabolism.

abstract：BACKGROUND/AIMS:Growth factors and their receptors play a role in healing ulcers of the rat. Somatostatin is a putative growth factor in the gastric mucosa with multiple functions mediated by specific receptors. Therefore, the distribution of somatostatin receptors was evaluated in the gastric mucosa of healing ulcers....
