摘要: 应用猫局灶性脑缺血模型,利用计算机控制的激光多普勒血流计,持续监测猫脑不同位置在脑缺血时的血流变化.结果:阻断大脑中动脉(MCA)后,猫脑颞叶和枕叶的脑血流迅速下降,分别为正常值的21.44%和23.61%;并在2h内缓慢下降,最终分别为正常值的15.74%和9.96%,除2h点外,二者无显著差异.提示:猫局灶性脑缺血时,其枕叶和颞叶的血流变化无显著差异.

Abstract: The purpose was to observe the changes of cerebral blood flow at different position using the model of the cats with brain ischemia.The middle cerebral artery (MCA) of every cat was occluded after craniotomy firstly, The animals were divided into two groups monitoring cerebral blood flow (CBF) continuously by Laser Doppler flowmetry in two hours: Group 1 (n=6), at temporal cortex; Group 2 ( n=6), at occipital cortex.After the MCA was occluded, the CBF whether at temporal or at occipital cortex reduced quickly to 21.44% and 23.61% of the normal value consequently.The CBF decreased slowly in two hours and reduced to 15.74% and 9.96% at last.The CBF had no statistics difference in 0 h, 0.5 h, 1 h, 1.5 h, except at 2 h.The change of the CBF at temporal and occipital cortex has no statistics difference in cats with brain ischemia.

Key words: brain ischemia, cerebral blood flow, laser doppler, cat
