本文采用放射性同位素铬标记红细胞,连继测定其放射性,计算前房积血的清除率,对尿激酶、透明质酸酶、20%甘露醇,治疗兔实验性前房积血的疗效进行了观察。选用2～3公斤健康杂种家兔20只,40只限,分为 A、B、C、D 四组。抽兔动脉血10毫升(肝素抗凝),用生理盐水洗一次,去上清液,血球构分再用盐水补足至10毫升,加入铬酸钠70μCi, In this paper, radioactive isotope labeled red blood cells, followed by determination of radioactivity, clearance rate of hyphema calculated, urokinase, hyaluronidase, 20% mannitol treatment of experimental experimental hyphema effect was observed . Selection of 2 to 3 kg of healthy hybrid rabbits 20, 40 limited, divided into A, B, C, D four groups. Rabbit arterial blood drawn 10 ml (heparin anticoagulant), washed once with saline, to the supernatant, blood components and then make up to 10 ml of salt water, add sodium chromate 70μCi,
