The analysis of alterations retina of during exposure of threshold laser intensity and opportunities to correct it by synthethic dipeptid. The material and method: 23 rabbits were included in the experiment. Recived matherial was investigated with help of light and electron microscopy. All layers of retina were damaged during laser exposure. The usage of synthethic dipeptide reduced laser damage. Synthethic dipeptid have retinoprotection abilities.

Renoprotective effect of antioxidants from group sterically hindered phenols (thiophane, dibornol) in white nondescript male rats (n = 55) subjected to influence of light intensity level 6 000 lx during 6 h was demonstrated. Course intragastric administration of thiophane limited of destructive changes in the retina, but didn’t bring to disappearance of lesion focuses. Dibornol prevented progression of local changes in the retina, contributed to decrease destruction of neurosensory cells, pigment epithelium and neurons of internal layer.

Антиоксидантный комплекс в условиях эксперимента на крысах-самцах линии Вистар эффективно снижает выраженность спаечного процесса в брюшной полости. Морфологическое исследование показало, что механизм действия антиоксидантного комплекса направлен на уменьшение воспаления, отека тканей и улучшение микроциркуляции в зоне повреждения.Ключевые слова: спаечный процесс, профилактика спайкообразования, антиоксидантный комплекс.Antioxidant complex under the experimental conditions in male rats of Wistar effectively reduces the severity of adhesions in the abdominal cavity. The morphological study showed that the mechanism of action of antioxidant complex is aimed at reducing inflammation, edema and improvement of microcirculation in the zone of damage.
