骨组织脱水后,用酒精和丙酮脱水的标本由于组织变脆,不易得到完整的切片;而用正丁醇脱水速度慢,所需时间长(24 h以上);用二氧六环和叔丁醇脱水虽然组织收缩小,但前者易挥发,有毒性,后者价钱较贵,不易普遍使用.笔者在工作中反复实践,对常规的骨组织脱水方法进行改良,收到了较好的效果. After the dehydration of bone tissue, samples dehydrated with alcohol and acetone were not easy to obtain complete slices due to the embrittlement of the tissues. However, the dehydration with n-butanol took a long time (more than 24 h); with dioxane and tert-butyl Alcohol dehydration although tissue contraction is small, but the former is volatile and toxic, the latter is expensive, not easy to use.I repeated practice in the work, the conventional methods of bone tissue dehydration improved, received good results.
