Clinical aspects of cardio-respiratory homeostasis.

Starting from general assumptions on the clinical aspects of homeostasis and on the functional correlations lung-heart in physiological and pathological states, the difficulty to diagnose an individual pulmonary heart disease is stressed, as well as the necessity to differentiate it from the cases of coronary heart disease, when respiratory failure aggravates the latent cardiac ischemia and induces a global cardiac failure. The diagnosis criteria of the two distinct pathological pictures are established, emphasizing the importance of this differentiation for clinical practice and epidemiological research.

Variation of correlation coefficient among aging and certain biological variables in man.

Researches concerning the variation of correlation coefficient (r) in man in relation to four sets of variables were carried out, namely: a set of ten fundamental variables (in which the dependent variable is represented by aging), a set of variational variables (variation ranks of the r), a set of reference variables (r, age, blood pressure, sex and ABO genetic system) and a set of relational variables (relations). This research contributes to the study of multidimensional variational network of the human gerontogenesis (G. Acilugaritei, 1993-1995).
