Abstract:
Objective To establish a rapid and specific method for identifying megkaryocytes under the light microscope and to provide a new method and new idea for diagnosis and differential diagnosis of blood diseases.Methods Unfixed smears of blood or born marrow were exposed firstly to an alcoholic solution of Basic Royol Blue for 5 min.Next, an equal amount neutral HEPES buffered solution of the same dye was added to the first stain solution.The two solutions were mixed by adding the second stain.After 10 min, the smears were washed for 2 min with flooding water and drained dry.Meanwhile, the stain was compared with traditional histochemistic stains and flow cytophotometer.Results Megakaryocytes showed purple red cytoplasm and bright blue nuclei.Platelet displayed purple red. Other blood cells(such as granulocytes、monocytes、lymphocytes、plasmacytes and ucleated erythrocytes) had no such stainning character. Compared with traditional histochemistic stains and flow cytophotometer, the stain of two steps by using Basic Royole Blue for megkaroblasts、promegkaryocytes and megkarocytes was credible and distinctive.Conclusion Basic Royol Blue for megkaryocytes stain was worth to contribute to the diagnosis and differential diagnosis of blood diseases.This technique can be used in clinical laboratory.
