Dynamics of the Pro-Oxidant/Antioxidant System Parameters in Wound Discharge and Plasma in Experimental Purulent Wound during Its Technological Liquid Phase Treatment.

The dynamics of the pro-oxidant/antioxidant system of rabbits was studied at the local (in exudate) and systemic (blood) levels during therapy of purulent wounds in liquid medium with the use of a programmed device and the efficiency of the proposed technological method was compared with that of classical methods for the treatment of these wounds. More rapid recovery of the indicators of the pro-oxidant/antioxidant system to physiological values in the postoperative period was observed after treatment by the proposed method (7 days vs. 10 days after standard treatment), these results attest to strengthening of the adaptation potential in laboratory animals. The intensity of free radical oxidation in the exudate decreased by 26.6% in animals treated by the technological method. These data indicated acceleration of the regenerative processes at the local level.

[Influence of linseed oil and deiterium depleted water on isotopic D/H composition and functional antioxidant defense of the hepatobiliary system in rabbits with carbon tetrachloride intoxication].

The article presents results of studying the influence of linseed oil and drinking diet with a modified isotopic composition with low deuterium content on indicators of prooxidant-antioxidant system during modeling of liver toxicity. The research was performed on 36 rabbits (weighing 3.1-3.5 kg) which were divided into 4 groups. Group 1 consisted of control animals; in group 2, 3 and 4 in rabbits the liver toxicity was modeled by administration of CCl4 (intraperitoneally, in the form of a 50% oil solution, 1 ml per kg bw, 2 times a week for 30 days); nutritional correction using flaxseed oil (0.1 ml per 100 g bw) and drinking diet with deuterium depleted water (50 ppm) was carried out in animals from groups 3 and 4 respectively, for 30 days prior to simulation of toxic hepatitis and more throughout the experiment. Using the method of nuclear magnetic resonance and mass spectrometry the influence of deuterium depleted water on D/H composition of the blood plasma, bile and liver tissues was determined: the deuterium concentration in these biological materials significant decreased. The most significant decrease in the deuterium content (30.2% compared with the control group) was found in bloodplasma in animals from group 4. The study of the state of prooxidant-antioxidant balance of the liver and bile showed oxidative stress at the local level, with the toxic effects of carbon tetrachloride. This was followed by EPR spectroscopy data pronounced increase of the number of paramagnetic centers in the hepatocytes by 5.4, 1.9 and 2.8 fold in animals of 2, 3 and 4 groups, respectively (compared to the indicators of the first group). There was also increase in the intensity of free radical oxidation processes in the bile with a simultaneous reduction of its antioxidant activity, which was significantly less distinct (on average 51.18-59.8%, p<0.05) in animals treated with nutritional correction, indicating that higher functional activity of protective systems involved in recycling prooxidant factors using dietary lipophilic antioxidants and water with low deuterium content. Overall, the results of the present study indicate that existing in the liver and bile autonomous mechanisms of regulation of the state of prooxidant-antioxidant systems are quite sensitive to the effects of antioxidant factors of lipophilic nature and shifts of isotopic D/H gradient, and suggest usefulness of the products that can affect these indicators to increase adaptive capabilities of the organism during intoxication.

[Total intravenous anesthesia in patients with postburn deformations of the face and neck]. / Totalnaia vnutrivennaia anesteziia u bolnykh c posleozhegovymi deformatsiiami litsa i shei.

Total intravenous anaesthesia was used in 1482 patients with postburn deformations of face and neck. Sodium hydroxybutyrate (SH) stimulating respiration at the expense of activation of cholinergic processes was the principal component of anaesthesia. The following protocols were used: 1) thalamonal-SH-seduxene-analgin, 23 cases; 2) barbiturates-SH-phentanyl-analgin, 182 cases; 3) seduxene-SH-phentanyl, 494 cases; 4) seduxene-SH-calypsol, 293 cases; 5) rogipnol-SH-phentanyl-calypsol, 394 cases; 6) dipidolor-SH-benzodiazepines (or barbiturates), 96 cases. All the operations were smooth, no serious complications were observed.
