[The influence of different types of physical exertions on the mature males' biological age].

We studied the biological age according to anthropometric indexes, mental, physical and both the types of working efficiency in 122 males at the age of 50-59 years. All of them were devided into 5 groups: untrained individuals, going in for general physical training, sport veterans, specializing in endurance training, sport plays representatives, weight-lifters. We found out a younger biological age in sport veterans, who were carrying out dynamic exertions.

[Biological age estimation by means of electroencephalography].

The indices of computer electroencephalography have been estimated in 183 persons at the age of 20-89. Test-programs and the method of biological age determination by computer electroencephalography have been elaborated. We have found three subpopulations in each age group--people with slowing-down, mean and accelerated age changes rate.

[Biological age estimation using echocardiography].

The indices of echocardiography have been estimated in 118 persons at the age of 20-89. Test-programs have been created and the method of biological age determination by echocardiography (ECHO-CG) has been elaborated. We found that there are three subpopulations in each age group people with slowing-down, mean and accelerated age changes rate.

[Congenital (hereditary) long QT syndrome: possible factors predisposing to development of ventricular tachyarrhythmias. Part II].

In 3 close relatives (mother, son, mother's first cousin) with long Q-T syndrome syncopal attacks were preceded by lowering of ionized calcium in peripheral blood. This mechanism is supposed to be a trigger of ventricular tachycardia in long Q-T syndrome.

[Changes in the oxidant-antioxidant system activity in patients with hepatic failure treated with hyperbaric oxygenation and actoprotectors].

Effects of hyperbaric oxygenation, bemitil, and solcoseryl used in preoperative treatment of patients with hepatic failure on the oxidant-antioxidant system are studied. Lipid peroxidation (LPO) was assessed from changes in the levels of malonic dialdehyde and diene conjugate and the antioxidant system from the number of SH-groups. Hyperbaric oxygenation led to activation of LPO processes.
