现已知道,醛复红(Aldehyde Fuchsin)是一种良好的生物学染料和组织化学试剂,在一定条件下,它能相对特异地显示弹性纤维、胰岛B细胞、肠道亲银细胞、垂体嗜碱性细胞、垂体后叶神经分泌物质、某些粘液细胞、肥大细胞,直至B型肝炎病毒表面抗原等。关于醛复红的发展史,Puchtler等人已作了简要的回顾。以往配制醛复红试剂时,不论是国内的还是国外的经验,都曾碰到有时着色不满意或者失败的情况。直到最近,Mowry才明确指出:配制醛复红应当用对品红(Pararosaniline),而不应当用碱性品红,因为后者是品红(Rosaniline)及对品红的混合物。对品红的结构式为 It is known that aldehyde Fuchsin is a good biological dye and histochemical reagent that shows relatively specific elastic fibers, pancreatic islet B cells, intestinal pro-silver cells, pituitary addictions under certain conditions Alkaline cells, pituitary neurosecretory substance, some mucus cells, mast cells, until the hepatitis B virus surface antigen and so on. Puchtler et al. Have briefly reviewed the history of the development of aldehyde complex red. In the past when formulating aldehyde complex red reagent, both domestic and foreign experience, have encountered sometimes unsatisfactory coloring or failure of the situation. Until recently, Mowry made it clear that formulating aldehyde complex red should use Pararosaniline instead of basic magenta because the latter is a mixture of Rosaniline and magenta. The structural formula for magenta is
