题1:答案A【题解】急性肾小球肾炎的组织病理学变化是双侧肾脏弥漫性的肾小球肿胀、肾小球内细胞增殖及侵润。在肿胀的肾小球内毛细血管袢相对缺血,造成肾小球滤过率下降,引起水钠潴留。后者是造成水肿的主要原因。在急性肾炎时血浆蛋白水平可因为水钠潴留而引起稀释性下降,一般不如大量蛋白尿引起的那样严重,故不是引起水肿的主要原因。以往不少人认为,急性肾炎时的水肿是由于毛细血管通透性增加所致,晚近已否定这种说法。由
Question 1: Answer A [Explanation] histopathological changes in acute glomerulonephritis of the bilateral renal diffuse glomerular swelling, glomerular cell proliferation and invasion. In the swelling of the glomerular capillary loop relative ischemia, resulting in decreased glomerular filtration rate, causing water and sodium retention. The latter is the main cause of edema. Plasma protein levels in acute nephritis may be due to Shuinazhuliu caused dilution decreased, generally not as serious as a large number of proteinuria, it is not caused by the main reason for edema. In the past many people think that the edema of acute nephritis is due to increased capillary permeability caused by the recent denial of this argument. by
