  A mathematical model of the metabolic process of formation of the hemostasis
in a blood-carrying vessel is constructed. As distinct from the earlier
developed model of the multienzyme prostacyclin-thromboxane system of blood,
this model includes, for the first time, the influence of the level of "bad
cholesterol", i.e., low-density lipoproteins (LDLs), on the hemostasis. The
conditions, under which the self-organization of the system appears, and the
modes of autooscillations and chaos in the metabolic process, which affects the
formation of hemostasis and the development of thrombophilia, are found. With
the aid of a phase-parametric diagram, the scenario of their appearance is
studied. The bifurcations of doubling of a period and the transition to chaotic
oscillations as a result of the intermittence are found. The obtained strange
attractors are formed due to a mixing funnel. The full spectra of Lyapunov's
indices, KS-entropies, "predictability horizons", and Lyapunov's dimensions of
strange attractors are calculated. The reasons for a change in the cyclicity of
the given metabolic process, its stability, and the physiological manifestation
in the blood-carrying system are discussed. The role of physiologically active
substances in a decrease in the level of cholesterol in blood vessels is
estimated.
