MUSCARINIC RECEPTOR SUBTYPES IN SMOOTH MUSCLE FROM THE BODY OF HUMAN STOMACH
Up to date, there are four pharmacologically characterized subtypes of muscarinic receptors (M1, M2, M3 and M4). In our study we have investigated muscarinic receptor subtypes in smooth muscle layers of human stomach. Isolated preparations of longitudinal and circular muscle layers from human stomach were used. Acetylcholine, bethanechol, carbachol, pilocarpine and AHR -602 produced concen...

متن کاملZataria multiflora Boiss inhibits muscarinic receptors of incubated tracheal smooth muscle with propranolol
Objective(s): In the present study, the effect of tissue incubation with propranolol on functional antagonism of Zataria multiflora Boiss (Z. multiflora) at muscarinic receptors of tracheal smooth muscle was examined. Materials and Methods: The effects of three concentrations of aqueous-ethanolic extract, 10 nM atropine, and saline on muscarinic receptors were tested on incubated tracheal smoo...
متن کاملHuman esophageal smooth muscle cells express muscarinic receptor subtypes M(1) through M(5).
Receptor characterization in human esophageal smooth muscle is limited by tissue availability. We used human esophageal smooth muscle cells in culture to examine the expression and function of muscarinic receptors. Primary cultures were established using cells isolated by enzymatic digestion of longitudinal muscle (LM) and circular muscle (CM) obtained from patients undergoing esophagectomy for...
متن کاملthe inhibitory effects of ferula assafoetida on muscarinic receptors of guinea-pig tracheal smooth muscle
conclusions these results showed an inhibitory effect for the extract of asafetida on muscarinic receptors of tracheal smooth muscle. results the ec50 obtained in the presence of higher concentration of the extract muscle was significantly higher compared to saline (p < 0.01). the maximum responses to methacholine in the presence of higher concentration of the extract (10 mg/ml) was significant...
