[Blastic transformation test in vascular diseases of the central nervous system]

The reported investigations were carried out in 99 cases. In 73 cases acute vascular diseases of the central nervous system were recognized, and 26 subjects served for control. In all cases the test of PHA-stimulated blastic transformation of the blastic index suggest reduced resistance of the organism and they may be group of patients was compared with the control group. The quantitative data were analysed statistically using the test of Student and the t T test of Student for paired samples. The obtained results showed that the proportion of lymphocytes undergoing blastic transformation after stimulation with PHA was in the control group 66.1% on the average, while in the group of patients it was decreased to 55.2%. These differences were significant statistically. The low values of the blastic index suggest reduced resistance of the organism and they may be used as a valuable indicator informing about the resistance of the patient.
