Abstract:
Objective To explore the nervous mechanism of intestinal function disorder after intestine congestion through observing the changes of acetylcholinesterase (AchE) neuron and nitric oxide synthase neuron (NOS) expression in nervous system of rat intestinal tract. Methods Sprague Dawley rats were divided into experimental groups (intestine congestion 20min and 60min group) and the control group. Then the spreading specimens of intestinal myen-teric plexus of ileums were collected and stained by AchE and nicotinamide-adenine dinucleotide phosphate-D (NADPH-d) histochemistry, to observe and compare the density of distribution and staining of AchE and NOS positive neurons. Result Compared to the control group, the number and positive expression of AchE positive neuron in intestinal myen-teric plexus of ileums in the experimental group rats decreased (P
