Pig bronchus

Nociceptin-induced inhibition of tachykinergic neurotransmission in guinea pig bronchus.

Nociceptin is a novel neuropeptide of the opioid peptide family recently identified as the endogenous ligand of the opioid receptor-like "orphan" receptor. Unlike other opioids, nociceptin has hyperalgesic effects in vivo. In the present study, nociceptin was found to inhibit electrical field stimulation-induced tachykinergic contractions of the guinea pig isolated bronchus preparation. The thr...

Absence of tachykinin involvement in leukotriene D4 and antigen-induced contraction of guinea pig isolated bronchus.

In guinea pig airways, contractions induced by leukotriene D4 or antigen are thought to be mediated primarily by an action of the agonist or of released mast cell-derived mediators directly on the airway smooth muscle cell. An indirect contractile action mediated by endogenous tachykinins also has been described for both of these stimuli. The present study evaluated the contribution of endogeno...

Tracheal bronchus.

A 65-year-old white woman was seen because of 2 episodes of mild hemoptysis complicating a persistent cough. Her medical history was positive for 8 years of mild shortness of breath and an indirect exposure to asbestos. Her review of systems was unremarkable and physical examination showed normal vital signs and blood oxygen saturation of 97% on room air. Air entry was normal and there were no ...
