Objective:To compare Lyon′s PAS standardized staining and traditional PAS staining.Methods:The sections of the same tissue were stained with the above two methods simultaneously.The results and replicability of the two methods were observed.Results:The posititive products and replicability of Lyon′s PAS staining were stronger than that of traditional PAS staining in the same tissue-sections.Coclusion:Lyon′s PAS standardized staining method is better than the traditional PAS staining method.
