Abstract

Under study was the influence of a single 3-minute-long exposure to ultrasound of high intensity (2 wt/cm2) upon intraorganic vessels of the liver in albino rats. The circulatory bed was examined 10 min., 5, 15 and 30 days after treatment with ultrasound. Methods ox injection, rentgenography, claering and histology revealed an unfavourable effect of ultrasound causing local construction of arteries and veins in early terms, uneven filling of the capillary bed with the injected mass, dilatation and deformity of capillaries. The above changes grew more pronounced during 15 days, by the end of the month they diminished but not disappeared.

摘要

研究了对白化病大鼠肝脏内器官血管单次3分钟高强度(2瓦/平方厘米)超声照射的影响。在超声治疗后10分钟、5天、15天和30天检查循环系统。静脉注射、X射线摄影、清除和组织学方法显示,超声产生了不利影响,导致早期动脉和静脉局部收缩,注射物质在毛细血管床填充不均匀,毛细血管扩张和变形。上述变化在15天内变得更加明显,到月底有所减轻但并未消失。
