Regional spinal cord blood flow and blood flow in different brain areas were measured in 18 rats by the microsphere technique. By the use of spheres labeled with two different isotopes injected 5 min apart, double determinations were made. The consistency of the results from the two injections was very good. Blood flow was highest in the lumbar part of the spinal cord, somewhat lower in the lower thoracic part, lowest in the upper thoracic part, and again higher in the cervical cord; the mean values of the two determinations were 0.98, 0.74, 0.42, and 0.48 ml X min-1 X g-1 tissue for these regions, respectively. The brain areas investigated were the brain stem, cerebellum, and right and left hemispheres; the respective mean values of the two blood flow determinations in these areas were 0.54, 0.58, 0.33, and 0.38 ml X min-1 X g-1 tissue.
采用微球技术对18只大鼠的脊髓局部血流及不同脑区的血流进行了测量。通过间隔5分钟注射两种不同同位素标记的微球进行了两次测定。两次注射结果的一致性非常好。脊髓血流在腰段最高,下胸段略低,上胸段最低,颈段又较高;这几个区域两次测定的平均值分别为0.98、0.74、0.42和0.48毫升·分钟⁻¹·克⁻¹组织。所研究的脑区包括脑干、小脑以及左右半球;这些区域两次血流测定的各自平均值分别为0.54、0.58、0.33和0.38毫升·分钟⁻¹·克⁻¹组织。
