Objective(s): Baicalein, a compound extracted from a variety of herbs, showed various pharmacological effects. This study evaluated the relaxant effects of baicalein and its underlying molecular mechanisms of action on rat’s isolated tracheal smooth muscle.Materials and Methods: Tracheal smooth muscle were contracted by 10 μM methacholin...

The contribution of endoplasmic reticulum (ER) and phosphorylation of phospholamban (PLB) to the relaxant effect of cGMP- and cAMP-elevating agents was studied in feline aorta. Sodium nitroprusside (NP, 100 microM) completely relaxed contracture induced by 10 microM norepinephrine. This NP-induced relaxation was partially prevented by tetraethylammonium, suggesting that a fraction of NP-induced...

Nigella sativa (N. sativa) is a spice plant which has been traditionally used for culinary and medicinal purposes. Different therapeutic properties including the beneficial effects on asthma and dyspnea, digestive and gynecology disorders have been described for the seeds of N. sativa. There is evidence of the relaxant effects of this plant and some of its constituents on different types of smo...

The ability of the M2 muscarinic receptor to mediate an inhibition of the relaxant effects of forskolin and isoproterenol was investigated in guinea pig ileum and trachea. In some experiments, trachea was first treated with 4-diphenylacetoxy-N-methylpiperidine (4-DAMP) mustard to inactivate M3 receptors. The contractile response to oxotremorine-M was measured subsequently in the presence of bot...

Saffron, Crocus sativus L. (C. sativus) is rich in carotenoids and used in traditional medicine for treatment of various conditions such as coughs, stomach disorders, amenorrhea, asthma and cardiovascular disorders. These therapeutic effects of the plant are suggested to be due to its relaxant effect on smooth muscles. The effect of C. sativus and its constituents on different smooth muscles an...

Motor depressant effects of diazepam were studied in the intact, decerebrate and high spinal cat. Diazepam (0.125516 mg/kg, i.v.) produced a depression of both the patellar and linguomandibular reflexes in the intact cat. In the high spinal (Cl) cat only the linguomandibular reflex was depressed. Facilitation and inhibition of the patellar reflex elicited in both intact and high spinal (Cl) cat...

Increasing epidemiological evidence supports the view, that quercetin has protective roles in a multitude of disease states in human who have a high intake of polyphenols. To investigate the ability of quercetin and its rutinoside, rutin, to modulate the relaxation of human airways smooth muscle and to determine the mechanism (s) of such relaxation, isolated human bronchus rings were suspended ...

This article concerns the synthesis and biological activities of some N-(1-(3,4-dimethoxyphenyl)propan-2-yl) amides as isoquinoline precursors compounds with smooth muscle (SM) relaxant activity. Aim: find activity compare it papaverine, an alkaloid that has been known a brain coronary vasodilator SM relaxant. Materials methods: In silico simulation PASS online program predicts for compounds. T...

Objective: The study was done to evaluate the antiasthma activity of Macerated and Soxhlet extracts of (pulp) of plant Liomnia acidissima Linn on tracheal chains of guinea pigs. Methods: The (pulp) of fruits of plant Liomnia acidissima Linn was extracted with 95% ethanol at 55oC and evaluate for their antiasthma activity on tracheal chains of guinea pigs by using three cumulative concentrations...
