[The effect of immunotherapy on the T system in lymphoma based on data from the theophylline test].

An analysis is presented of the sensitivity of theophyllin test to the level of endogenous modification of E-receptors on T-cells of the peripheral blood and lymph nodes of mice with lymphoma in conditions of immunotherapy with native and Kon A or cholera neuroaminidase treated lymphoma cells. A marked inhibition of the endogenous character of theophyllin-sensitive cells in lymph nodes of mice in all methods of immunotherapy and an increase of the number of theophyllin-resistant cells, more significant in mice immunized with Kon A treated cells.
