[State of the T- and B-system of immunity in normal cerebrospinal fluid from persons of different age groups]. / Sostoianie T- i B-sistemy immuniteta v normal'noi spinno-mozgovoi zhidkosti u liudei razlichnykh vozrastnykh grupp.

The paper is concerned with studies of the T- and B-immunity systems in the CSF in 37 patients, in whom the CSF was extracted in order to perform spinal anesthesia. This was necessary for surgical operations because of cryptochidism (16 patients aged from 16--30) and hypertrophy of the prostate (21 patients aged from 60 and over). The patients of both groups showed no signs of nervous system lesions. A comprehensive immunomorphological analysis of the CSF cells permitted to detect the medium indices of the T- and B-immunocompetent cells of individuals depneding upon the age.
