[Changes of pulmonary tissue area density and their mechanisms in rats with hypoxic pulmonary hypertension].

Objective: To investigate the changes of pulmonary tissue area density and their mechanisms in rats with hypoxic pulmonary hypertension (HPH).

Methods: 54 Wistar rats were divided into hypoxia 10 d (n = 12), 20 d (n = 12), 30 d (n = 12) groups and control group (n = 18). The rats in hypoxia groups were exposed to a simulated hypoxia environment at a height of 5 km above sea level to establish HPH models.
