[A method of studying the initial regulatory activity of blood cells in lymphocyte transformation reaction]

The authors suggest a simple method for studying the lymphocyte blastogenesis (LBG) regulation in whole blood culture, consisting in preincubation of a part of the material and comparison of the results in two variants of the experiment: upon immediate mitogen stimulation and stimulated in 24 hrs after pre-cultivation. LBG activation or suppression is established from the value of the preincubation index.
