Described an original stromal staining method; it allows them neatly in blood smears off RBCs. Were also stained with the same method the "solenoids bodies" ("Halbmondkörper" in German, "bodies crescent" in Castilian, "crescent bodies" in English and "corps in demilune" in French), which, as we will to demonstrate in a forthcoming are a variety of stroma and its meaning has been clarified through the method. A small modification in the method yields very good colorations of organisms such as Bartonella baciliformis, Treponema pallidum, and Trichomonas Laverán Hematozoon vaginalis. It should be tested in other microorganisms.

Disclosed cytologic features of a cell type with diagnostic value in chickenpox , called Giant Cell Features , Multinucleated Giant Cells , Atypical cells or " pseudotumoral " . These cells acquire cyto logical morphologically distinguishable characteristics , dye , quantitative , and fine percentage , according to the stage of the rash variceloso are. In phase transparent vesicle are usually round or oval , with one or two giant nuclei , acidophilic staining affinity discreetly . In phase turbid or opalescent vesicle there is a tendency of irregular deformation of cells and nuclear multi-segmentation ( multinucleated ) and acquire more acidophilic staining in the previous phase. At the stage of pustule are often spherical with giant core and take an acidophilus frankly coloring with Leishman . The cytoplasm of these cells is scarce and generally takes basophilic staining in the three ph...
