Three-Factor Kinetic Equation of Catalyst Deactivation.

The three-factor kinetic equation of catalyst deactivation was obtained in terms of apparent kinetic parameters. The three factors correspond to the main cycle with a linear, detailed mechanism regarding the catalytic intermediates, a cycle of reversible deactivation, and a stage of irreversible deactivation (aging), respectively. The rate of the main cycle is obtained for the fresh catalyst under a quasi-steady-state assumption.

[Positive effect of cytoflavin on metabolic status changes in patients with burn disorder].

Complex clinical and laboratory examination of 60 patients with moderate level of burn damage included determination of the content of intermediate products of lipid peroxidation (LPO) (malonic dialdehyde, diene conjugate, SH groups and tocopherol) in blood and peripheral zone of the skin and hypodermic tissue. At the same time, the activity of superoxide distumase (SOD) and catalase was evaluated. This examination was performed on the first and third days after injury, in the period of burn shock.

[A new method of preoperative modeling of perosseous osteosynthesis for fractures of the humerus bone and forearm bones].

The aim of the investigation was to improve results of treatment of patients with fractures of the humerus and forearm bones by complex treatment using numerical processing of video-information and computed modeling of the operation of perosseous osteosynthesis. A personal computer equipped with means for lead-in and visualization of the image was used for an analysis of rentgenograms. Among 144 patients treated for fractures of the humerus and forearm bones there were 83 treated using the method of perosseous osteosynthesis.

[Prospects for computer modeling technology of osteosynthesis in fractures of bones of the lower limbs].

To improve the results of treatment of the patients with femur and shin bone fractures the digital processing of video-information and computer simulation of perosseous osteosynthesis were used. The roentgenogram analysis was conducted using the personal computer equipped with the tolls for image input and visualization and software for data processing. 235 patients with femur and shin bone fractures were treated.
