Preventive 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Inhalational insulin was withdrawn from the market due to its potential to produce airway hyper-reactivity and bronchoconstriction.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. ...
متن کاملDynamics of smooth muscle contraction
Photolysis of caged calcium (Nitr5, Calbiochem®) can be used to studycalcium dependent processes such as excitation-contraction coupling andmuscular mechanics. Expensive high energy light sources are routinely used forUV light exposure; this study describes an alternative low cost Xenon flash unitconstmcted in our laboratOlY. A 300 J short arc Xenon flash lamp (Heimarl1l®)wa...

متن کاملHistamine-induced rhythmic contraction of hog carotid artery smooth muscle.
Smooth muscle strips isolated from the hog common carotid artery can contract rhythmically, exhibiting low frequency, large amplitude oscillations in tension when stimulated with 10 microM histamine. Strips required at least 1.45 mM calcium and 2.5 mM potassium to exhibit this rhythmic activity. Rhythmic contractions could be converted to tonic contractions by removal of potassium or ouabain tr...
متن کاملHypocapnia-induced contraction of porcine airway smooth muscle.
Hypocapnia constricts peripheral airways in vivo. This study investigated the role of airway smooth muscle in this phenomenon and the mechanism of hypocapnia-induced contraction in vitro. Isometric tension, intracellular pH (pHi) and intracellular free calcium concentration ([Ca2+]i) were measured in porcine airway smooth muscles suspended in organ baths in the presence of 5% or 0% CO2. In trac...
