Smooth muscle relaxing drugs and guinea pig ileum.
The effects of various smooth muscle relaxing drugs on contractile responses to acetylcholine (ACh), Ba2+ and Ca2+, and on the tissue cyclic AMP levels were examined in the guinea pig ileum. Papaverine and theophylline caused a decrease both in the maximum height and the slope of dose-response curves induced by the three stimulants, and an increase in the cyclic AMP levels. Diltiazem and D-600 ...
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Inhalational insulin was withdrawn from the market due to its potential to produce airway hyper-reactivity and bronchoconstriction.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. ...
متن کاملSoluble Relaxing Factor from Muscle*
Gergely, Briggs, and Kaldor (24) have recently shown that the so called Marsh-Bendall relaxing factor consists of a granular component and a heat labile dialyzable cofactor. The requirement for both components could be demonstrated for the inhibition of Mg++-activated myofibrillar adenosine triphosphatase, for the inhibition of the adenosine triphosphate-induced syneresis of myofibrils and for ...
متن کاملThe Nature of the Muscle-Relaxing Factor
Analysis of the effects of deoxycholate and benzalkonium chloride on granule relaxing activity, myofibril and glycerinated fiber responses to ATP, and the sensitivity of these actomyosin-containing systems to relaxing factors have established that it is possible to differentially inactivate intrinsic granule relaxing factor. It is therefore possible to use these agents to treat myofibrils and g...
متن کاملThe Possible Involvement of Nitric Oxide/Endothelium Derived Relaxing Factor in Atropine-Induced Vasorelaxation
Atropine has been used to block cholinergic neurotransmission in basic research. Large doses of atropine cause vasodilation of the blood vessels in the skin. This effect is apparently unconnected with the antimuscarinic activity of atropine and seems to be due to a direct action on the blood vessels. It has been suggested that atropine blocks muscarinic receptors at low doses and it induces th...
