内源性吡啶核苷酸烟酰胺腺嘌呤二核苷酸的还原形式的荧光被用于绘制猫脑中的缺血区域。一个显着的微观异质性模式的荧光增加导致的临界水平的不完全脑缺血。荧光模式表明缺血最初发生在穿通脑动脉之间的微分水岭区。
The fluorescence of the reduced form of the endogenous pyridine nucleotide nicotinamide adenine dinucleotide was used to map regions of ischemia in cat brain. A remarkably microheterogeneous pattern of increased fluorescence resulted from a critical level of incomplete cerebral ischemia. The fluorescence pattern suggests that ischemia occurs initially in microwatershed zones between penetrating cerebral arteries.
