用ASM68k型图像分析仪测量正常豚鼠耳蜗侧壁外放射状细动脉、集合静脉、血管纹毛细血管网、动静脉吻合支的管径,结果表明:①其管径与一般相应的微血管管径基本一致。②耳蜗各周外放射状细动脉管径有明显差异,底周最大,从底周至顶周逐渐变细,此特点在研究耳蜗侧壁微血管变化时应充分考虑。

The ASM68k image analyzer was used to measure the diameters of radial arterioles, collecting veins, capillary network of blood vessels and arteriovenous anastomotic branches in normal guinea pigs. The results showed that: (1) Their diameters were basically consistent with those of the corresponding corresponding microvessels . ② There was a significant difference in the diameters of the radial arterioles outside the cochlea, with the largest basal circumference and tapering from the end of the week to the top of the week. This feature should be fully considered when studying the changes of microvascular in the side wall of the cochlea.
