查询词典 hypoxia

Chronic hypoxia and MCT-induced pulmonary hypertension are associated with excess collagen deposition in pulmonary arteries; meanwhile, the muscularization of nonmuscular intra-aeinar arteries also plays an important role in maintenance of pulmonary hypertension.

1。在慢性缺氧和MCT诱发的肺动脉高压进展过程中，肺动脉壁胶原沉积过度，泡内动脉结构发生改变，动脉中层厚化，非肌性动脉肌性化。2.764-3能部分抑制胶原的过度沉积，降低缺氧性及野百合碱性肺动脉高压，从而逆转泡内动脉的结构改变。

Hypoxia increased the percentage of intra-acinar muscular and decreased the one of nonmuscular artery. 764-3 could reduce MA% from 33.75±11.26 (H2w) to 21.25±5.86 (7-H2w, p＜0.05) and from 41.50±10.70 (H4w) to 26.67±10.92 (7-H4w, P＜0.05), respectively; meanwhile, increase NMA% from 35.42±9.00 (H2w) to 45.42±2.92 (7-H2w, p＜0.05) and from 21.50±9.29 (H4w) to 33.33±5.40 (7-H4w), p＜0.05, respectively.

与正常组大鼠相比，缺氧2周、4周后MA％明显增加，分别为33.75±11.26(＜0.001)和41.50±10.70(p＜0.01)；NMA％显著减少，分别为35.42±9.00(p＜0.001)和21.50±9.29(p＜0.001)。764-3处理的大鼠其三型血管比例的失调得到部分改善。7-H2w组与7-H4w组MA％分别为21.25±5.86和26.67±10.92(p均＜0.05)，NMA％为45.42±2.92和33.33±5.40(p均＜0.05)。
