Background &Aims:Gaseous transmitters, such as nitric oxide （NO） and carbon monoxide （CO）, are a family of regulatory molecules that involved in regulation of physiological functions of mammalian, including human beings. Hydrogen sulphide （H2S） is a chemical hazard of gas production. It is colorless and smells like rotten eggs. Relatively high endogenous levels of H2S have [...]
The modulation of Gastrointestinal tract is dominated not only by autonomic nerve, but also regulated by independent enteric nervous system (ENS). However, ENS of specific regulating mechanisms of the gastrointestinal tract to be remained. So the further interpretation about the mechanism of ENS -regulated gastric motility is very important to the clinical treatment of gastrointestinal [...]
Objective:Taking the rats as the research object which have abnormal gastrointestinal motility and observing the levers of gastric residual rate, intestine propulsion rate,brain-gut peptide hormones and enteric neurotransmitters in order to explore the mechanism of renal capsular block on the regulation of gastrointestinal motility.Methods:1. seventy-two Sprague-Dawley rats were randomly divided into three groups. Group A [...]
Oxytocin (OT) is a nonapeptide. The wellknown physiological function of OT was to regulate uterine contractions and milk ejection reflex in humans and rats. In recent years, more and more studies indicated that both OT and OTR mRNA were expressed throughout the human gastrointestinal (GI) tract and might be involved in the regulation of GI [...]
Many people take a great interest to the mechanism of prolifira-tion, differentiation and exclusion of the intestinal epithelia. Generally considered that these process are regulated by endogenous growth stimulation factors and growth inhibitors. In this paper main studied on growth inhibitor. Abroad presented the presence of inhibitory substance with biological activity for intestinal cell prolifira-tion [...]
Normal liver has the unique capacity to regulate its growth in an exquisite homeostatic mechanism, maintaining constant tissue mass relative to levels of metabolic stress in the body. This property is particularly remarkable because hepatocytes as cells rarely divide in their normal state. In both small mammals and humans, throughout the life of the organism, [...]
The lower esophageal sphincter (LES) in human beings lies between the esophagus and the stomach. It not only guarantees that food bolus in the esophagus pass into the stomach, but also prevent the gastric contents reflux into the esophagus. Thus, the structural or functional abnormality in the human LES may result in a number of [...]
