[Observation of immune function in 115 elderly patients with pulmonary tuberculosis].

This paper tested the indexes of the cellular immunity and the humoral immunity of initially treated 115 old patients with pulmonary tuberculosis, and the data were compared with these values of healthy elder and youth and middle aged patients with pulmonary tuberculosis. The results showed that the indexes of the cellular immunity elderly patients with pulmonary tuberculosis decreased (LTT Et-RFC Ea-RFC the discrepancy significantly, P less than 0.05), and the index of the humoral immunity increased (the varying of all the indexes P less than 0.01) compared with the health elders. All the immune indexes of the old pulmonary tuberculosis had no significant difference except for IgA compared with youth and middle aged patients.
