title: [Natural killer cells in middle-aged and elderly tuberculosis patients].
abstract: The immunological study of 76 patients belonging to two age groups (group 1 consisting of 46 patients aged 60-85 years and group 2 consisting of 30 patients aged 20-40 years) was made. For control, healthy persons aged 60 years and older (30 subjects) and 20-40 years (28 subjects) were examined. The study revealed that, in contrast to the tuberculosis patients of the younger age group, the old-age patients exhibited a decrease in the activity of natural killer (NK) cells. The greatest decrease in the activity of NK cells was observed in patients with chronic fibrocavernous forms of tuberculosis (in comparison with other forms of tuberculosis).
