摘　　要：我们最近的经验表明,甲基丙烯酸树脂或石蜡包埋的组织块,放置或保存几年之后会变干、变脆,所切组织切片在切片时较易碎裂;把组织块放在湿盒里湿润过夜或几天后再切,可避免或减少这种碎裂。Our recent experiences demonstrate that methacrylate resin or paraffin embedded tissue blocks will dry and become brittle after storage for a few years,and tissue sections cut from them will be more likely to break in sectioning. The breaking can be prevented or reduced by sectioning after moistening the blocks within a wet box overnight or for a few days.
