[The acute period of brain concussion: the dynamics of the clinical and neuropsychological symptoms].

Analysis of significant correlations between clinical and neuropsychological symptoms in 104 young patients with no anamnesis load, made in the acute period of brain concussion (BC), has demonstrated that the intensity of clinical symptoms correlates with the grade of disorders of higher mental functions (HMF). Besides, significant correlations were discovered between neuropsychological symptoms of brain stem injury and disorders of energy supply to HMF as well as between clinical symptoms of the involvement of the limbic-diencephalic structures and disorders of arbitrary control and emotional disturbances which are determined by the involvement into the pathological process of the anterior parts of the right and left cerebral hemisphere. The dynamic of clinical and neuropsychological symptoms after BC lies in the regression of disorders of stem nonspecific system, diencephalic and limbic structure functions.

[Clinico-psychological mechanisms of compensation for disorders of brain activities in patients with traumatic lesions of the polar-basal sections of the frontal lobes].

Twenty-five patients were subjected to surgical ablations of contused or crushed polar-basal regions of frontal lobes. Two groups were singled out: 1, compensated; and 2, subcompensated. "Lobar syndrome" which includes motor disorders and impaired psychic selectivity, planning, regulation and control of psychic activity and behavior, was to a several extent characteristic of all the patients.

[The renin-aldosterone profile in hypertension].

Simultaneous study of renin activity and aldosterone concentration in the blood plasma of 180 out-patients with hypertensive disease has shown that persons with normal or increased reninemia predominate in the I stage of disease. Moderate positive correlation was observed between the level of aldosterone and renin activity; aldosterone-renin index at the stage of the disease remains unchanged. In stage II of hypertensive disease renin activity diminishes and the concentration of aldosterone in blood plasma rises, aldosteronerenin index is enhanced at the expense of aldosterone predominance, which is most often seen in the sub-group of patients with low reninemia.
