METHODS: Thirty male SD rats were randomly divided into control group, stress group and NG-nitro-L-arginine methyl ester group. The rat model of water immersion-restraint stress was established. The expression of nNOS in colonic submucous plexus and myenteric plexus in the rats was examined by immuno-histochemical staining and analyzed by computer image analysis system.
