Key result
Prolonged passive smoking elevates plasma noradrenaline and impairs endothelial relaxation in systemic rabbit arteries.
Why the study?
The effect of prolonged passive smoking on plasma catecholamine levels and arterial reactivity was examined to understand vascular impairment mechanisms.
Does prolonged passive smoking impair endothelium-dependent relaxation in isolated rabbit arteries?
Does prolonged passive smoking impair endothelium-dependent relaxation in isolated rabbit arteries?
Prolonged passive smoking impairs endothelium-dependent relaxation in systemic arteries, potentially mediated by nitric oxide degradation by superoxide anions.

Hypothesis-generating in rabbits; leaves open whether passive smoking impairs endothelial function in humans.
Török et al. (2000) studied this question. Prolonged passive smoking was evaluated on Plasma catecholamine levels and reactivity of isolated rabbit arteries. Prolonged passive smoking for 3 weeks significantly elevated plasma noradrenaline levels and impaired endothelium-dependent relaxations of systemic arteries in rabbits.
