[Influence of erythrocyte destruction kinetics on the dynamic behavior of the erythropoiesis system].

A simple mathematical model was used to analyse the influence of cell destruction kinetics on the dynamics of erythropoietic system. Two ways of erythrocyte destruction were compared: random destruction and destruction of cells at their maximum age. It has been shown that mostly used description of erythrocyte destruction as a random process results in a great stability increase (about three times in the critical feedback coefficient). Oscillations with large periods (20 divided by 200 days) may exist in the system.

[Nonlinear resistance in a diffuse trigger system. Biological barrier].

Mathematical model of antagonistic interrelations of biological species in which the migration is taken into account is considered. The ecological nish, occupied by one of the antagonistic species cannot be populated by the other if the initial quantity of the new species does not exceed the particular value. This is considered as the demonstration of the ecological barrier. The approach to the investigation of the nonlinear stability for spatially distributed systems can be applied to other biophysical problems.

[Mathematical model of an immune response. II. Stochastic aspects].

In the mathematical model describing the development of infection and its suppression with antibodies worked out of the course of the delayed immune response a problem of complete destruction of antigen is considered. A method of calculating the probabilities of antigen destruction is advanced. The optimal cure tactics is discussed. It is shown that the highest probability of the destruction of antigene is achieved if the serum is injected in the moment of antibodies peak and when the cure with antibiotics is started at the antigen maximum.
