在病理组织的制片过程中,需要大量的酒精和二甲苯,它们的浓度与切片质量有着直接关系。组织经过固定和水洗含有大量水份,在浸蜡和包埋以前必须将组织中的水分脱去。我科常用的脱水剂为两次95％酒精,两次100％酒精,重复进行脱水,以保证脱净组织中的水分。二甲苯是组织脱蜡,浸蜡的媒剂透明过程中必用试剂,一般是以两次更换二甲苯,甚至三次更换。以前我科用过的酒精和二甲苯全部扔掉,浪费很大。为了保证制片质
In the pathological tissue preparation process, requires a lot of alcohol and xylene, their concentration and slice quality has a direct relationship. Tissue after fixing and washing contains a lot of water, in the wax before embedding and embedding the water must be removed. Our department commonly used dehydration agent twice 95% alcohol, twice 100% alcohol, repeated dehydration, to ensure that the net organization of the water. Xylene is the tissue dewaxing, waxing agent transparent medium will be necessary reagents, usually two times to replace the xylene, or even three replacement. Before our department used alcohol and xylene all throw away, waste a lot. In order to ensure production quality
