[Myocardial cytoprotection with trimetazidine in patients with ischemic heart disease during surgical stress].

Fluctuations of the thiol disulfide system were shown to be interrelated with changes in the ECG indices. Trimetazidine since it has antioxidant properties was found to be effective in patients with low thiol disulfide ratios. A single dose of 0.

[Relief of visual fatigue in visual strain-related work].

Work associated with visual strain results in visual fatigue. Laser radiation in red part of spectrum relieves visual fatigue, activating reduction-oxidation thiol disulfide system in eyes.

[The dynamic indices of the thiol-disulfide system and of the electrocardiogram under conditions of surgical stress].

Changes of the thiol-disulfide balance and electrocardiographic indices were studied in ischemic heart disease patients undergoing operation stress. It was shown that the operative procedure resulted in a shift of the redox state to oxidation in the thiol-disulfide system, especially in its protein part. The revealed correlation between the value of the thiol-disulfide ratio and ECG changes attest to the significance of the state of the blood thiol-disulfide system for the assessment of the degree of ischemic alterations in the myocardium.

[The role of antioxidant mechanisms in body's reactions to the effects of low-intensity laser irradiation].

Some mechanisms of general and local effects of laser radiation with various wavelength were considered. Both stimulating and stress effects of low-intensive laser radiation realized via antioxidant and free-radical pathways were shown. It was found that the level of SH and SS-groups in tissues and blood is the most sensitive index of laser effect.
