title: [Coefficients of correlation of clinical laboratory data as signs of mechanisms of regulation].
abstract: Differences in the coefficients of correlation of clinical laboratory signs in patients with diseases of the blood and lymph, respiratory organs, and cardiovascular system were analyzed using OMIS research biomedical system (Intellectual Systems, St. Petersburg. 1993). Correlation coefficient is interpreted not as a measure of relationship between signs, but as an indicator of regulation processes in a live organism. The coefficients of correlation are most frequently different for the signs whose mean values are unchanged under the same conditions. This means that a comparative analysis of relationship between the signs largely contributes to such branches of medicine in which the conclusions are based on analysis of the mean tendencies. Such branches are primarily new tests for early diagnosis of tumorous diseases, assessment of dissemination and malignancy of the process, understanding of the processes of malignant degeneration, etc. Automated analysis of differences in correlations may be useful to decipher the ambiguous and dynamic relationships between different submultiplicities of immunocompetent elements in different forms of immune response (and in various states of the organism). Use of the new system opens new vistas in studies of the signs of vital activity of cardiovascular and respiratory systems. Not only new mechanisms regulating the hemodynamics, respiration, and cardiorespiratory relationships were disclosed; relationships between physiological parameters and cellular elements were revealed, which could be hardly suspected before. A fragment of a study of survival factors in acute nonlymphoblastic leukemia (carried out in cooperation with N.N. Mamayev) is presented for illustration. A close positive relationship between the humoral and cellular immunity (at least of their components analyzed in this study) is demonstrated to be destructive for patients with acute nonlymphoblastic leukemia. An optimal variant is their independent regulation or regulation leading to variously directed changes.
