[Use of mathematical models in study of nitric oxide, myoglobin and cell oxygen regimen].

The influence ofnanomolar concentrations of NO on oxygen regimen of muscle cells was investigated. The intracellular distribution of oxygen consumption rates, pO2, NO and myoglobin was calculated by mathematical modeling of diffusion reactions of O2, NO and myoglobin in the muscle cell. The diffusion of O2, and NO from blood vessel surface into cell was taken into account.

[Oxygen transport in skeletal muscles working with its maximum consumption during hypoxemia].

The influence of acute hypoxia (35 < or = PaO2 < or = 100 mmHg) on the values of VO2max and parameters of oxygen transport in muscle working at VO2max was studied under different values of muscle blood flow F (80 < or = F < or = 120 ml/(min 100g), blood pH (7.0-7.6), and different diffusion conditions.
