Romanovsky to study a detailed structure of the causative agent of malaria, to find its kernel, to describe morfol. changes of plasmodiums at influence of quinine and to install the mechanism of its specific action on the causative agent of malaria, and also to formulate (to P. Ehrlich) philosophy of chemotherapy inf. diseases in general and malaria in particular (etiotropic and organotropic influence). The method of coloring offered by D. L. Romanovsky was widely adopted in various fields of biology and medicine, hl. obr. in modification of the German researcher G. Giemsa — see. Romanovsky — Gimza a method .
