[A morphometric method of studying blood lymphocytes].

Basing on the literature data and their own findings the authors prove the reliability of the method for assessment of the lymphocytic system of the body. They demonstrate that various endo- and exogenous effects on human body may result in similar abnormalities of the respective lymphocytic systems regardless of the origin and parameters of these effects. The nonspecific nature of this phenomenon permits the assessment of the status of a given system in any kinds of effects and body conditions.
