项目摘要
The purpose of this investigation was to : (1) develop reliable Doppler techniques to observe of organ blood flow in the kidney, hepatic vessels and cardiac cavities in the cattle, and (2) asses the potential usefulness of Doppler ultrasound to diagnosis and evaluate organ functions.1) A pulsed Doppler ultrasound scanner (EUB-450) with liner and convex type 3.5 MH_z.5.0 and 7.5 MH_z scan head was used for all examination. Ultrasound scans were performed on cattle in standing position.2) Clinically normal calves and cows were selected for investigate a basic Doppler techniques including scanning position, target organs and there vessels. In calves, the artery of the right kidney and hepatic vessels including the portal vein and intrahepatic vein, were able to detect the blood flow and the velocity. In adults, it was difficult to obtain a blood flow in the kidney because the vessel is in deep from the skin surface.3) In calves, HgCl_2 was administered to produce kidney disorder. After given the HgCl_2, velocities of blood flow in the kidney, portal vein and hepatic vein were measured for 24-30 hours. In some cases. Velocity of blood flow in the kidney was increased according to kidney lesion develop, but hepatic blood flow showed no changes. In other cases, blood flow in the kidney did not change. So, it was concluded that there is some difficulties to diagnostic evaluation of organ disorder by the blood flow.4) In cases with heart disease including dilatative cardiomyopathy and endocarditis of adult cows, the blood flow of the portal vein and hepatic vein showed decrease according to severity with congestive heart failure. From these observation, a information for early diagnosis of the disease may be Oained by measuring the hepatic blood flow.
这项研究的目的是:(1)开发可靠的多普勒技术,以观察牛的肾脏血流,肝血管和心脏腔中的器官血流,以及(2)(2)提出多普勒超声诊断和评估器官的潜在实用性函数。1)脉冲多普勒超声扫描仪(EUB-450),带有衬里和凸型3.5 MH_z.5.0和7.5 MH_z扫描头进行所有检查。在站立位置上对牛进行了超声扫描。2)选择临床正常的犊牛和奶牛来研究基本的多普勒技术,包括扫描位置,目标器官和容器。在犊牛中,右肾脏和肝血管的动脉(包括门静脉和肝内静脉)能够检测到血流和速度。在成年人中,由于血管从皮肤深处处于深处,因此很难在肾脏中获得血流。3)在犊牛中,HGCL_2被施用以产生肾脏疾病。在给予HGCL_2之后,测量肾脏,门静脉和肝静脉的血流速度24-30小时。在某些情况下。根据肾脏病变的发展,肾脏中血流的速度增加了,但肝血流没有变化。在其他情况下,肾脏中的血液流动不会改变。因此,得出的结论是,血流对器官疾病的诊断很难诊断。4)在患有心脏病(包括扩张性心肌病和成年母牛心内膜炎)的病例中充满充血性心力衰竭的严重程度。从这些观察结果中,可以通过测量肝血流来提高疾病早期诊断的信息。
