[Luminescence parameters of nuclear blood cells during the immune response process].

The synthetic activity of nuclear blood cells in the process of immunization of rabbit with ovalbumin was studied by luminescence microspectroscopy . We followed the parameter alpha, the ratio between the intensities of the red (640 nm) and green (530 nm) components of the luminescence spectrum of acridine orange fluorochrome cells. The antiserum titre was determined too. The data obtained make it possible to correlate the increase in alpha of the immunocompetent cells with the content of antibodies synthesized by these cells in response to the protein antigen. It has been shown that within definite limits the parameter alpha does determine the synthetic activity of the immunocompetent cells.
