Effect of sodium metabisulphite on bronchial blood flow in conscious sheep: pharmacological modulation.

abstract：:The concentration of intracellular free Ca2+ ( [Ca2+]i) in human blood platelets was measured by use of the fluorescent probe quin-2. 5-Hydroxytryptamine (5-HT) caused a rapid increase of [Ca2+]i in the presence or absence of Ca2+ in the medium. The [Ca2+]i-rise was less marked in the absence of Ca2+ and could be anta...
