摘　　要：分离12具老年男性尸体（老年组）和9具青年男性尸体（青年组）的前列腺动脉，连续血管横切面切片显微镜下观察前列腺动脉血管内径及血管壁厚度。老年组年龄（67±9）岁，前列腺动脉均存在不同程度的硬化斑块，血管内膜增厚，最窄处血管内径为（452±97）μm，血管内膜厚度（228±82）μm，内径／内膜比值为3．14±0．68；青年组年龄（34±4）岁，前列腺动脉内膜光滑，距前列腺外膜5mill处的血管内径为（864±17）Ixm，血管内膜厚度（574±4）μm，内径／内膜比值为15．524±0．18。老年人较青年男性存在不同程度前列腺动脉血管内膜增厚及管腔狭窄。Prostatic artery of 12 elder and 9 younger cadavers were isolated and transected. Vascular inner diameter and thickness of vascular wall of these cross sections were observed microscopically. Atherosclerotic plaque could be seen in the prostatic artery of 12 eiders. And there were the thickening of tunica intima and the narrowing of inner diameter. The inner diameter of elderly prostatic artery was （452± 97） μm, the thickness of their tunica intima （228± 82 ）μm and inner diameter/thickness 3.14 ± 0. 68. Tunica intima of 9 younger prostatic arteries were glabrate. The inner diameter of younger prostatic artery was （864 ±17）μm, the thickness of their tunica intima （57 ± 4） μm and inner diameter/thickness 15.52 ± 0. 18. Statistically significant differences existed between elder and younger cadavers in the above 3 parameters. As compared with younger counterpart, prostatic artery of elders was more stenotic and its tunica intima tended to be thicker.
