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。
The shape and size of erythrocytes of plateau pika and plateau tail hare living in the area of Guoluo and Dabu were studied by scanning electron microscopy morphometric method and compared with similar data of rabbits in plain control group and experimental rabbits in moving plateau The results showed that the erythrocyte diameter (X) and the straight area (X) of the indigenous rodents in the two plateau were close to those in the plain control group, but significantly lower than those in the plateau experimental group (P <0.01). Therefore, it is considered that the adaptation of plateau indigenous animals to plateau hypoxia mainly through maintaining a high level of red blood cell number, reducing the volume of red blood cells, thereby increasing the total surface area of erythrocyte membrane to oxygen diffusion, reducing plasma viscosity, accelerating blood oxygen Transport to achieve.
