摘要
应用扫描电镜形态计量研究方法,对生活在果洛大武地区的高原鼠兔、高原发尾野兔的红细胞形态、大小进行研究,并与平原对照组家兔以及移居高原实验家兔的同类数据相比较结果表明;这两种世居高原的土著啮齿动物的红细胞直径(X)和内凹区直经(X)与平原对照组接近,但明显低于高原实验组(P<0.01)。由此,认为高原土著动物对高原低氧环境的适应主要是通过维持较高水平的红细胞数目,减小红细胞体积,从而增加红细胞膜对氧扩散的总表面积,降低血浆粘滞度,加速血液氧的运输来实现。
Using the scanning electron mieroseope, the erythrocytic size and shape of the O-chotona Curzoniae Hodgson and the hare which lived in high altitude, were studied and were compared with those of plain -control-group rabbits and experimcntal ones whichimmigrated into plateau The result showetl that the mean RBC diameters and the meanerythrocytic internal concave diameters of these two kinds of natural rodents are similarto plain-control group, but slgniflcantly lotver thtln the expermental group's (P<0.01).
