To determine the role of the epithelium in the responses to adenosine of isolated trachea from ovalbumin-sensitized guinea pigs.Spirally cut tracheal preparations were superfused or immersed in organ baths and transversely cut strips were immersed. E

Inhaled adenosine causes bronchoconstriction in asthmatics and may modulate inflammatory cell activity. Elevated adenosine levels occur in the lungs after antigen challenge of asthmatics.The aim of this study was to investigate whether the bronchocon

This study investigated whether a correlation between airway hyperreactivity (AHR), leukocyte influx, and nitric oxide (NO) existed in guinea pigs chronically exposed to lipopolysaccharide (LPS). The effect of the corticosteroid, dexamethasone, or ph

The effects of in vitro incubation of rat isolated left atria, pulmonary artery rings, and aortic rings with isoprenaline (10(-6) M for 6 h) were examined to compare the degree of desensitization of beta1- and beta2-adrenoceptor-mediated functional r

To determine whether antigen challenge is associated with increased accumulation of leukocytes in the lungs, the pulmonary accumulation of 111In-labelled neutrophils and eosinophils was monitored by gamma scintigraphy.Guinea-pigs were sensitized with

The physiological and pharmacological consequences of repeated aero-allergen challenge have not been previously characterized in conscious, sensitized guinea-pigs.This study was undertaken to compare the effects of two anti-inflammatory compounds, de

The action of the adenosine agonist, 5'-(N-ethylcarboxamido)-adenosine (NECA), at extracellular A2 receptors of guinea-pig and rabbit aortic rings was investigated. A near-maximum relaxant concentration (10(-5) M) of NECA was determined from cumulati

A structural model for a ligand-receptor-Gs alpha-protein complex to function as a GTP synthase is presented. The mechanism which is dependent on the movement and rotation of the G alpha-protein alpha 2-helix is seen to involve the delivery of, at le

An alignment of beta 1-adrenoceptor alpha-helices on the bacteriorhodopsin model is compared with an equivalent alignment to m2-muscarinic alpha-helices. A proposed mechanism of ligand-activated trans-membrane proton transfer within alpha-helices III

Guinea-pig isolated left atria, paced at 2 Hz were incubated with 86rubidium (86Rb) for 120 min. They were then washed every 2 min for 2 hr, each sample being retained for scintillation counting. Left atrial isometric tension was recorded simultaneou
