...L. Låstbom; A. Falk-Filipsson; S. Boyer; P. Moldéus; Å. Ryrfeldt Inhaled 3-carene at a concentration of 5,000 mg/m 3 caused bronchoconstriction in isolated, ventilated and perfused guinea pig lungs. This effect was inhibited by the cyclooxygenase inhibitor diclofenac (100 µ M ) and the thromboxane...

After administration of the placebo, SP produced a dose-related bronchoconstriction with a geometric mean PD 20 of 0.15 mg. After SCG, the mean PD 20 value was of 0.64 mg (p < 0.01...

Lundberg; Åke Ryrfeldt; Peter Moldéus The mechanism of sulfur dioxide-induced bronchoconstriction was studied using isolated perfused and ventilated guinea-pig lungs. They were exposed to sulfur dioxide after pretreatment...

...Tahir Ahmed; Ignacio Danta We studied the comparative modification of histamine- and methacholine-induced bronchoconstriction by a calcium antagonist, gallopamil, in 8 subjects with bronchial asthma. Dose-response curves to aerosolized methacholine or histamine were performed, without and following...

Because one consequence of mast cell activation is the release of platelet-activating factor, we wondered whether thromboxane levels would be increased during acute bronchial constriction...

...Kingman P. Strohl; Steven M. Scharf; Robert Brown; Roland H. Ingram, Jr. In 8 anesthetized mongrel dogs, we studied the effects of carbachol-induced bronchoconstriction (BC) on the cardiovascular system. Inhalation of carbachol in an amount sufficient to produce at least a 50% decrease in lung...

At the same time we obtained the determination of bronchoconstriction degree by measuring the forced expiratory volume in 1 s (FEV 1 ) and the airway resistance (Raw) by plethysmographic technique. In 10 asymptomatic patients with normal bronchoconstriction indexes, we...

...T. Todisco The oto-respiratory (O-R) reflex consists of the cough reflex produced by direct mechanical stimulation of the deep portion of the posterior wall of the external auditory meatus. Because the efferent pathways are different for coughing and bronchoconstriction, some subjects can have an O...

Histamine diffuses in relatively high amounts through the mucosa of the upper part of the airtract into the arterial plasma. Ascaris extract causes bronchoconstriction from the upper part...

It appears that the combination of verapamil inhalation (low dose) and atropine reduced the anticholinergic effect of atropine causing marked bronchoconstriction. This unexpected result depends...
