ABSTRACT

Objective:To investigate the effects of thyroid motilin(MTL) on migrating motor complex(MMC) in fasting rats.Methods: The distribution and quantitative expression of motilin in the thyroids were detected by immunohistochemistry and radioimmunoassay.We also observed the effect of thyriod motilin on the MMC by recording the gastrointestinal motility in conscious rats.Results: Tail vein injection of MTL increased MMC in antrum and duodenum in a dose-dependent manner,as manifested by increased contraction frequency and amplitude(P
