[Immune indices in tuberculosis, lung cancer and chronic pneumonias]

Some immunological tests were made and lipid peroxidation studied in 147 tuberculous, 76 lung cancer and 48 lingering pneumonia patients. Blast-transformation reaction proved inhibited, absolute and proportional number of large leukocytes was low, while circulating immune complexes grew in number, tuberculin specific tests appeared insignificant in all the above diseases. Both initial and end lipid peroxidation products (dienic conjugates and malonic dialdehyde, respectively) accumulate noticeably both in tuberculosis and pneumonia, whereas in cancer only dienic conjugates increased in number. In all the groups antioxidant activity of the serum and lymphocytes lowered and correlated with CIC levels.
