LP-YS3 also elevated motilin (MTL), endothelin (ET), acetylcholinesterase (AChE), substance P (SP), and VIP serum levels and reduced somatostatin (SS) levels in constipated mice.
Taken together, UDO, which can be easily obtained through milling to a satisfactory particle size, exhibited obvious laxative effect in diphenoxylate-induced constipated mice, and the mechanism might be associated with elevated levels of AChE, Gas, MTL, SP, and reduced production of SS.
