Hydro-ethanolic Extract of Portulaca oleracea Affects Beta-adrenoceptors of Guinea Pig Tracheal Smooth Muscle
The stimulatory effect of the extract of Portulaca oleracea (P. olerace) on β-adrenoceptor of tracheal smooth muscle was examined. To examine β-adrenoceptor stimulatory effect, concentration response curve to isoprenaline was obtained in pre-contracted tracheal smooth muscle in the presence of three concentrations of aqueous-ethanolic extract, propranolol and saline. Values of EC50 (the effecti...

متن کاملPreventive effects of ipratropium and salbutamol against insulin induced tracheal smooth muscle contraction in guinea pig model
Inhalational insulin was withdrawn from the market due to its potential to produce airway hyper-reactivity and bronchoconstriction. So the present study was designed to explore the acute effects of insulin on airway reactivity of guinea pigs and protective effects of salbutamol and ipratropium against insulin induced airway hyper-responsiveness on isolated tracheal smooth muscle of guinea pig. ...
