dc.description.abstractAlthough M1, M2 and M3 muscarinic receptor subtypes were identified in smooth muscles of the stomach from frog, rat, dog and swine, subtypes of this receptor were not characterized in human and feline stomach. The aim of this thesis was to identify and characterize muscarinic receptor subtypes in longitudinal and circular smooth muscle layers from the body of human and feline stomach. Pharmacological analysis of muscarinic receptor subtypes was conducted on isolated preparations of circular and longitudinal smooth muscle layer from the body of human (42 specimens) and feline (109 specimens) stomach. Acetylcholine-induced tonic contractions of circular muscle layer from the body of human stomach were blocked strongly by hexocyclium (pA2=9.92), telenzepine (pA2=9.86), scopolamine butylbromide (pA2=9.68), trihexyphenidyl (pA2=9.42) and atropine (pA2=8.91), moderately by pirenzepine (pA2=7.41) and weakly by gallamine (pA2=5.60) and pFHHSiD (pA2=5.84). Tonic contractions of longitudinal muscle layer from the body of human stomach were blocked strongly by hexocyclium (pA2=9.19), telenzepine (pA2=9.37), scopolamine butylbromide (pA2=8.67), trihexyphenidyl (pA2=9.72) and atropine (pA2=8.56), moderately by gallamine (pA2=7.18) and weakly by pirenzepine (pA2=6.25) and pFHHSiD (pA2 not calculated). Tonic contractions of circular muscle layer from the body of feline stomach were blocked strongly by trihexyphenidyl (pA2=9.20), atropine (pA2=8.96), hexocyclium (pA2=8.94), scopolamine butylbromide (pA2=8.38) and pFHHSiD (pA2=7.98) and moderately by gallamine (pA2=7.32), pancuronium (pA2=7.28), pirenzepine (pA2=7.14) and telenzepine (pA2=7.09). Tonic contractions of longitudinal muscle layer from the body of feline stomach were blocked strongly by atropine (pA2=9.57), hexocyclium (pA2=9.43), trihexyphenidyl (pA2=9.13), telenzepine (pA2=8.65) and pFHHSiD (pA2=8.88), moderately by gallamine (pA2=7.97) and pancuronium (pA2=8.06), and weakly by pirenzepine (pA2=6.87) and scopolamine butylbromide (pA2=6.41). Circular and longitudinal muscle layers from the human stomach are dominated by M1 muscarinic receptor subtype, while in the circular and longitudinal muscle layers from the feline stomach dominant subtypes of muscarinic receptor are both M1 and M3.en
