二甲苯价格低廉,透明效果好,病理科常规应用于脱水和染色程序中。为保证组织脱水和染色效果需要及时更换二甲苯,由于二甲苯对中枢神经系统具有慢性毒性作用,产生的废液处理过程中又会对环境造成二次污染。应用CBG回收仪实现对二甲苯重复回收使用,不仅能节约试剂购买的成本而且保护了环境。本文对再生二甲苯应用到组织脱水和染色过程中效果进行评价,探讨再生二甲苯在常规病理HE染色过程中应用的可行性。
Xylene low price, good transparency, pathology routinely used in dehydration and dyeing procedures. In order to ensure the tissue dehydration and dyeing effect, the xylene needs to be replaced in time. Due to the chronic toxicity of xylene to the central nervous system, the secondary pollution of the environment will be caused during the treatment of the waste liquid generated. The use of CBG recovery instrument to achieve recycling of para-xylene recycling, not only can save the cost of reagent purchase but also protect the environment. In this paper, the effect of regenerated xylene on tissue dehydration and dyeing was evaluated, and the feasibility of regenerated xylene in routine pathological HE staining was discussed.
