Abstract:
Abstract Making a "thoracic window" on the right thoracic wall of an animal, changes of the surface pulmonary microcirculation in Wistar rats (n=60) in vivo were observed during acute alveaolar hypoxia (Fi=0.1,3minutes), by using intravital microscopic-video recording TV system. The data showed that: (1). Internal diameter (ID) of pulmonary arterioles (20-90?m) decreased markedly, ID of group Al (≥60?m), A2 (40-59?m), and A3 (20-39?m), were decreased by 18.00%, 15.10%, and 9,59%, respectively, and ID of venules (20-100um) were decreased by 12.43% during hypoxia (P
