根据新月体形成的多少,作者把66例患者分成三组,第Ⅰ组新月体<50%的有23例,第Ⅱ组新月体为50～80％的有24例,第Ⅲ组新月体>80％的有19例。主要症状为急性少尿或无尿,常有几天至几周的肉眼血尿,1/5病例为肾病综合征。多数病例有高血尿素(>40mg/dl)、高血清肌酐(72mg/dl)及高血压(>140/90mmHg)。相当多数的病人有发热、喉痛,其中4例细胞培养分离出溶血性链球菌,再加上另外的6例,都表现抗“O”滴度升高。作者用清晰的摄影机以平面几何的办法把新月体及肾小球血管丛的界限定下来,新月体占肾小球的体积<25%的为小型,占25～50%的为中型,>50%的为大型。在第Ⅰ组中新月体占肾小球体积的7～22％,新月体为细胞性,纤维细胞性或纤维性粘附在完整的肾小球囊的基底膜上。第Ⅱ组的新月体占肾小球体积的23～48％。第Ⅲ组的新月体占肾小球总体积48～72%,在Ⅱ、Ⅲ组中可以看见新月体各期的演变,有
According to the number of crescent formed, the authors divided 66 patients into three groups, the first group of 23 cases of crescent <50%, the second group of 50 to 80% of 24 cases, the third group Crescent body> 80% of 19 cases. The main symptoms of acute oliguria or anuria, often a few days to weeks of gross hematuria, 1/5 cases of nephrotic syndrome. Most cases have high blood urea (> 40mg / dl), high serum creatinine (72mg / dl) and high blood pressure (> 140 / 90mmHg). A significant number of patients had fever and sore throat. Four of the four cell cultures isolated hemolytic streptococci, plus an additional six, showed elevated anti-“O” titers. The author uses a clear camera geometry approach to the crescent and glomerular vascular plexus set the limit, the crescent of the glomerular volume <25% for the small, 25 to 50% for the medium, > 50% for large. In group I, the crescent volume accounts for 7-22% of the glomerular volume, the crescent is cellular, and the fibrocystic or fibrous adhesion to the intact glomerular basement membrane. The second group of crescent accounted for 23 ~ 48% of the glomerular volume. Group Ⅲ crescent accounted for 48-72% of the total volume of glomerular, in group Ⅱ, Ⅲ can be seen in the evolution of the crescent phase, there
