Acute effects of exercise on cognition in patients with chronic obstructive pulmonary disease.

abstract：:The involvement of platelet-activating factor (PAF) in bronchial hyperresponsiveness (BHR) in bronchial asthma has been controversial. To determine whether PAF is involved in BHR in humans, we carried out a randomized, double-blind, placebo-controlled, two-phase cross-over study on the effects of Y-24180, a potent, sp...
