Effect of P-glycoprotein inhibition at the blood-brain barrier on brain distribution of (R)-[11 C]verapamil in elderly vs. young subjects.

abstract：:Responses of human bronchial strip preparations to contractile and relaxant agonists were measured in preparations from non-diseased and from asthmatic lung obtained 3-15 h post-mortem. The potencies of carbachol and histamine were approximately two times less in asthmatic than in non-diseased bronchi. This was statis...
