[Radiodiagnosis of early-stage nephroangiopathy in children with arterial hypertension].

A total of 115 children aged 13-17 years (mean age 15.77 +/- 1.89 years, 98 boys and 17 girls) with essential arterial hypertension (EAH) were examined.

[Significance of modernization of the social rehabilitation system within promotion of the nursing care].

A specially elaborated system-module approach, that contributes to shaping, in medical students, the moral principles for their occupational activity, is suggested. A continuous humanistic-training system embracing the educational and pedagogic processes is elaborated; the system is a principally new type of orientation of medical personnel aimed at the medical-and-psychological adaptation and rehabilitation of elderly population.

[Methods of cardiac synchronization in assisted circulation].

In assisted circulation cardiosynchronization should be regarded as a process of monitoring the arterial blood pressure within the limits of the cardiac cycle and changes of its form with the aim of improving the energy balance of the heart. The coordination of the pumping function and that of the cardio-vascular system comes to a problem of shaping the monitoring action that depends upon three variables, viz. the time lag tepsilon, actuation of the unit relative to the base cardiosignal, duration of the pumping phase tpi and the signal level at the pump's inlet U(t).

[Apparatus for cardiosynchronized artificial circulation].

The development of outfits for ancillary circulation is oriented towards improvement and construction of new pneumatic, hydraulic and electromechanical actuating systems--units intended for an optimal disposition of pressure waves moving from the pump to the aorta, etc. An inference is drawn about advantages and perspectives offered by functionally monitored actuating units, as well as about the need for the pulsating stream to pass through the low-power side intended to pre-set the shape of the pressure curve.
