The Crenation and Flagellation of Human Erythrocytes

Artifacts, With Other Nonspecific Appearances Resembling Virus Particles, and the So-Called Filamentous Forms of Influenza and Fowl Pest Viruses in Human Skin Tissue Fluid Examined With the Electron Microscope

“…The formation of filaments at the erythrocyte periphery w-ith and wvithout detachment has been observed under varied circumstances and writh a variety of provoking agencies. For instance, filament formation may occur in living erythrocytes from the human and other species (Kite, 1914;Seifriz, 1927;Auer, 1933); in unhemolyzed erythrocytes under various conditions of standing (Kite, 1914;Oliver, 1914;Takeuchi, 1929;Auer, 1933); in unhemolyzed erythrocytes from preparations subjected to hemolysis (Bechhold, 1921;Salen, 1921;Rockwood, 1924); and in hemolyzed erythrocytes from several species under various chemical and physical treatments (Bechhold, 1921;Rockwood, 1924;Furchgott, 1940).…”
