Summary: | We evaluated the proportion of classic plaques among all of the senile plaques in four Alzheimer brains (frontal, temporal, occipital and hippocampal areas) by the usual method of two-dimensional analysis using a single methenamine silver-stained section and three-dimensional analysis using a set of serial sections. Three-dimensional analysis showed the number and percentage of classic plaques to be 2-5 times greater than those revealed by two-dimensional analysis. In the hippocampal area of one case, no classic plaques were found by two-dimensional analysis but three-dimensional analysis showed that some classic plaques were present. From these findings, it is suggested that three-dimensional analysis using serial sections is indispensable for subclassifying senile plaques. |
