1 Responses of preparations of human and porcine isolated bronchus and pulmonary artery to carbachol (CCh), methacholine, histamine, 5-hydroxytryptamine (5-HT), (-)-noradrenaline (NA), (-)adrenaline (Adr) and (+/-)-isoprenaline (Iso) were compared with responses to the same agonists in isolated lung parenchyma strips. 2 All preparations from both human and porcine lung contracted in response to histamine and all, except preparations of porcine pulmonary artery, contracted in response to CCh. Human and porcine pulmonary artery and parenchyma strip contracted in response to NA while bronchial preparations invariably relaxed. Iso caused relaxation of human and porcine bronchus and parenchyma strip. Although 5-HT was completely inactive in tissues isolated from pig lung, this amine was a powerful spasmogen in human pulmonary artery, relaxed human bronchus and caused variable responses in human parenchyma. 3 Results indicate that the pharmacological characteristics of human and porcine parenchyma strips may be explained in terms of responses of vascular or airways smooth muscle.
