title: [Problems of cytochemistry of leukocytes].
abstract: In investigating the atypical granula in myeloic cells cytochemically the positivity of DMAB reaction identifies the specific eosinophilic nature of these granula. The slightly modified methods of representing histones allow those histones which are rich of lysine and arginine to be differentiated. With their help those differences can be grasped which exist between the condensed chromatin of lymphocytes and the mature neutrophils caused by the presence of histones being rich of lysine and arginine. New possibilities of examining the proteins in leukocytes in a cytochemical way as well as in blood- and bone-marrow cells are provided by colouring with palatine fast black, the use of which also points to certain differences in the chromatin of lymphocytes and neutrophils.
