Animal modeling was carried out to change the blood perfusion of the pig tongue, and the temperatures on the surface of the tongue at the correspond-ing blood perfusions were measured to study the relation between the blood perfusions and the temperatures on varied positions of the tongue surface.

采用多种先进仪器和手段，在大量动物实验的基础上，通过对动物造模改变猪舌的血液灌注率，测试相应条件下的舌面温度，得到舌表面不同位置处的温度与血液灌注率之间的关系。

The model well mimicked the hearts in vivo. Perfusions were performed at a constant 1. 5kPa left atrial preload and 10.7kPa aortic afterload.

该模型较好地模拟了在体心脏做功时的工作状态，使左心房前负荷保持在1.5kPa，主动脉后负荷保持在10.7kPa。

Results 99Tcm-ECD SPECT: 19 of the 20 patients showed brain cortex single focus or multiple foci which were either local or diffuse. The perfusions in the abnormal areas were decreased prominently.

结果 99Tcm-ECD SPECT 示：20例脑积水患儿中19例显像异常，异常率为95%，其中显示脑室扩大者8例（40%）。19例脑灰质异常者分别表现为单个或多个，单侧或双侧、对称性或非对称性、局灶性或弥漫性的放射性减低区，异常减低区的范围大小、数目、程度与临床病情相关。

Perfusion in the right parietal lobe in group2 was significantly lower than in group1 (P.01).（2）Average perfusions were higher in the right temporal and parietal lobes than in the left in all 3 groups.（3）Gray matter volumes were significantly smaller in group3 than in group2 (P.05); total cerebral spinal fluidsvolumes were significantly larger in group3 than in group1 and group2（P.05）; right hippocampus volumes were significantly smaller in group3 than in group1 （P.05）. Conclusions Age-related change of cerebral blood perfusions in the healthy elderly over 65 years is characterized with hypoperfusion in the right parietal.

结果（1）经方差分析，第2组和第3组脑组织几乎所有部位的灌注均低于第1组，其中第2组右顶叶灌注的放射性计数比值为0.87±0.18，低于第1组（RAR=0.98±0.17；P.01）；（2）经配对t检验，除第2组的双侧顶叶外，3组颞叶和顶叶的灌注均为右侧高于左侧（P.01和0.05）；（3）经方差分析，第3组的灰质体积占颅内容积的百分比［（47.59±1.26）%］小于第2组［（49.43±1.30）%］，总脑脊液体积占颅内容积的百分比［（14.61±3.16）%］大于第1组［（12.41±0.73）%］和第2组［（11.94±1.27）%］，右侧海马体积［（2.04±0.23）cm3］小于第1组［（2.27±0.20）cm3］，P均。05。
