Normal values for hypoxic and hypercapnic ventilaroty drives in man.
To better determine the range of normal values of hypoxic and hypercapni ventilatroy drives in man, these drives were measured in 40 males and 4 females between 21 and 51 yr of age. The averageExpand

Neuromuscular relaxants as antagonists for M2 and M3 muscarinic receptors.
BACKGROUND Neuromuscular relaxants such as pancuronium bind to M2 and M3 muscarinic receptors as antagonists. Blockade of muscarinic receptors in atria of the M2 subtype mediates tachycardia. In theExpand

Lipopolysaccharide-induced sensitization of adenylyl cyclase activity in murine macrophages.
LPS is known to modulate macrophage responses during sepsis, including cytokine release, phagocytosis, and proliferation. Although agents that elevate cAMP reverse LPS-induced macrophage functions,Expand

Actin reorganization in airway smooth muscle cells involves Gq and Gi-2 activation of Rho.
Extracellular stimuli induce cytoskeleton reorganization (stress-fiber formation) in cells and Ca2+ sensitization in intact smooth muscle preparations by activating signaling pathways that involveExpand

In vivo measurements of airway reactivity using high-resolution computed tomography.
Changes in airway resistance are reported to account for only a portion of changes in total lung resistance. The fraction of total lung resistance caused by airway resistance is difficult to quantifyExpand

Anesthesia for Laser Surgery
Laser surgery offers several advantages to the surgeon and patient: microscopic precision, a bloodless operative field, and complete sterility. While the majority of procedures pose few problemsExpand

Inhibitory effects of thiopental, ketamine, and propofol on voltage-dependent Ca2+ channels in porcine tracheal smooth muscle cells.
BACKGROUND Intravenously administered anesthetics directly inhibit airway smooth muscle contraction. Because many anesthetic agents affect membrane ion channel function and sustained contraction ofExpand

Serotonin induces constriction and relaxation of the guinea pig airway.
The response of guinea pig trachea to 5-hydroxytryptamine (serotonin; 5-HT) was investigated by studying tracheal strips suspended in organ chambers for isometric tension measurements. SerotoninExpand

Carbachol-induced actin reorganization involves Gi activation of Rho in human airway smooth muscle cells.
To determine whether M2 muscarinic receptors are linked to the monomeric G protein Rho, we studied the effect of carbachol on actin reorganization (stress fiber formation) in cultured human airwayExpand
