چکیده    Background: the petal's hydro-alcoholic extract of rosa damascena mill. on ileum contractions of wistar rats and its possible mechanism were investigated. methods: forty-eight male wistar rats were divided into six groups. ileum was placed adjacent to propranolol (1 μm),naloxone (1 μm) and l-name (100 μm) and also under the influence of different doses (2-8 mm) of calcium chloride. results: cumulative extract of r. damascena mill. (100,500,and 1000 mg/l) decreased ileum contractions induced by kcl (60 mm) in a dose-dependent manner (p < 0.0001). propranolol and naloxone significantly decreased the inhibitory effect of the extract on contractions induced by kcl (p < 0.001),but l-name was ineffective. furthermore,calcium led to the contraction of depolarized tissue through kci and this contractile effect decreased significantly induced by the cumulative concentrations of the extract (p < 0.001). conclusions: the results indicate that r. damascena mill. dose-dependently (100,500,and 1000 mg/l) decreases ileum movements of the rat probably through stimulating the β-adrenergic and opioid receptors and voltage-dependent calcium channels,and it may be used to treat digestive disorders.
