Abstract:
The hypoxic pulmonary vasoconstriction (HPV) in Yunan monkey has been observed. The results showed that acute alveolar hypoxia caused significant pulmonary hypertension, associated w~th art increase in pulmonary vascular resistance. The maximal response appeared 3 min after onset of hypoxia. Monkey may be proposed as moderate responder in HPV. The HPV in monkey was blocked by lipoxygenase inhibitor diethylcarbamazine and enhanced by cyclooxy genase blocker...indomethacin. It is suggested that lipoxygenase metabolites leukotrienes probably play the role of a mediator in HPV of monkey, whereas cyclooxygenase metabolites prostaglan dins act as medulator.
