[The immunologic status during pulmonry tubercuolsis].

The cellular and humoral immunity of patients with pulmonary tuberculosis has been evaluated prospectively in 22 PPD-positive and 10 PPD-negative patients by intradermoreaction (IDR), blast transformation (SL) and MIF production in response to PPD, Candida and varidase, peripheral lymphocyte count, and quantitative evaluation of immunoglobulins. There is a very good correlation between the different tests, and anergy is frequently found in elderly patients. Negative results (IDR, SL, MIF) are significantly observed in the presence of a negative PPD-IDR, lymphopenia (less than 1,000/mm3), impaired blast transformation in response to PHA (less than 21,000 cpm), and a cavitary form of tuberculosis. These findings suggest a defect of cellular immunity in these patients.

Mutagenicity of trimethylphosphate in mice.

Subtoxic concentrations of trimethyphosphate, administered orally or parenterally to male mice, produced mutagenic effects, dependent on dosage, in the dominant lethal assay.
