[Antioxidant status evaluation in sportsmen using in their ration natural concentrated food products made by cryogenic technology].

The authors evaluated the level of products of lipid peroxidation and enzymatic component of antioxidant defense in 30 sportsmen (19-22 years) going in for boat racing at pre-competition period, after competition and during one month of subsequent planned training. At the same time, the authors assessed some indices of vitamin (А, Е, В, В) and mineral status of human organism (zinc, copper, iron). As the criteria of antioxidant defense status, catalase activity and ceruloplasmin level were detected in blood serum, content of products of lipid peroxidation was evaluated according to levels of malon dialdehyde and nitric oxide metabolites.

[Course of wound process in chemical burns of the stomach (results of morphological and endoscopic studies)].

The dynamics of the wound process in chemical burns of the stomach were studied on the basis of histological and endoscopic examinations. The patients who were studied were given nonoperative treatment, in all cases for corrosive gastric ulcers. The most frequent complications were cicatricial stenoses (86.

[Surgical tactics in patients with postburn cicatricial esophageal stenosis].

Surgical policy during the first years after burn was aimed at the recovery of natural nutrition. To achieve that, esophageal bougienage (503 cases) or total retrosternal esophagoplasty from the large intestine (192 cases) were performed. The authors hold that in order to attain complete medical rehabilitation for the patients, it is necessary to remove all the cicatricially changed tissues.

[Changes in the lungs in the early period of closed trauma of the thorax in rats].

In experiments on rats it has been demonstrated that in the acute period of uninjured parts of the lungs periodic changes of protein, lipid and glucose concentrations developed. In uninjured parts of the lungs one can observe more concentration of lipids and in injured parts-more glucose. The changes of substrates, concentrations in the lungs are due to not only the changes of venous blood excess in the lungs, but are connected with metabolic changes in the cells of the injured and uninjured parts of the lungs.
