- The pathological hallmark of PAH is the narrowing of pulmonary arterioles secondary to endothelial cell dysfunction and smooth muscle cell proliferation. 其病理标志是肺动脉狭窄,继而继发血管内皮细胞功能异常和平滑肌细胞增殖。
- Electron microscopy showed that structure of the endothelial cells in pulmonary arterioles in group HC was near to normal,and the proliferation of medial smooth muscle cells and collagen fibers in adventitia was much lighter than those of group HH. 电镜下,HH组肺细小动脉中膜平滑肌细胞增生,面积增大,染色质增多,外膜胶原纤维密集,HC组大鼠肺细小动脉内皮细胞结构基本正常,胶原少见,中膜平滑肌细胞和外膜胶原纤维增生较HH组明显为轻;
- Light microscopy showed WA/TA (vessel wall area/total area) and PAMT (media thickness ratio of pulmonary arterioles) were significantly lower in rats of HP group than those of HH group(P< 0.01). HP组的肺细小动脉管壁面积 /管总面积比值 (WA/TA)和中膜厚度 (PAMT)均明显低于HH组 (P <0 .;0 1);且低于HL组 (P <0
- Situ hybridization showed the average value of integral light density (LD) of eNOS mRNA in pulmonary arterioles was significantly higher in rats of LL group than that of HH group and LA group(P<0.01). HH组的肺细小动脉eNOSmRNA的平均吸光度值低于NC组 (P <0 .;0 5 );LA组高于HH组 (P <0
- wedge pressure of pulmonary arteriol 肺[小]动脉楔压
- wedge-pressure of pulmonary arteriol 肺(小)动脉楔压
- Lung regional radionuclide count (LRC) was correlated with pulmonary arteriole density ( arterioles per square centimeter, APSC, APSC=0.001317LRC-342.3148 (P<0.01), r=0.57). Conclusion: PPI correlates with pathologic findings. 双肺核素总计数 (LRC)与每平方厘米肺小动脉计数 (APSC)正相关 ;回归方程APSC =0 0 0 1317LRC - 342 3148(P <0 0 1) ;相关系数 0 5 7。

- Open lung biopsis was carried in 47 cases of congenital heart defect with pulmonary hypertension, the amount of pulmonary arteriole were calculated, and compared with the early result of operation and Heath Edwards classification in pathology. 对47例先天性心脏病并肺动脉高压症患者作术中肺活检,并对肺切片中单位面积小动脉数量与术后早期结果作比较:发现肺动脉高压症患者单位面积肺小动脉数量明显下降,并且与Heath?Edwards肺血管病理定性分级的轻、重程度有关;
