作者曾报告大芦荟(蜈蚣掌)分离物对放射线所致的小鼠皮肤障碍具有强的防护作用,此次就这些分离物对以致死量的X线照射后的生存防护效用与造血功能损害的防护作用进行了检讨。 ①生存防护效用试验:取ICR雄性小鼠,于软X线4.1KR照射5分钟前,腹腔内给予大芦荟分离物。在照射后的30天内观察小鼠的生存天数,求出生存防护效用。②造血功能障碍防护作用:以软X线0.5KR照射2次或5次.经时从眶静脉丛采血,测定外周血中的白细胞总数、中性粒细胞、淋巴细胞、红细胞及血小板数。造血前驱细胞(CFU-S):按
The authors have reported that Aloe argentea extracts have a strong protective effect against radiation-induced skin disorders in mice. This time the survival of these isolates against lethal doses of X-ray radiation protection and hematopoietic function of the damage The protective effect was reviewed. 1 survival protection effect test: Take ICR male mice, 5 minutes before soft X-ray 4.1KR irradiation, intraperitoneal administration of Aloe vera isolates. The survival days of the mice were observed within 30 days after the irradiation to determine survival protection effects. 2 hematopoietic dysfunction protection: exposure to soft X-ray 0.5KR 2 or 5 times. Blood collected from temporal venous plexus over time to determine the total number of white blood cells in peripheral blood, neutrophils, lymphocytes, red blood cells and platelet count. Hematopoietic precursor cells (CFU-S): press
