[Pseudoplaque formation in immunologic reactions].

It has been proved by diverse experimental methods that cell suspension prepared from the immunocompetent organs and tissues by Jerne's method modified by N. N. Klemparskaya presents a hypertonic medium stimulating formation of false plaques. This evidence suggests that immune-like plaques (aureola) may be formed in the absence of antigen rather than due to lysis of red cells or destruction of plaque-forming cells.
