Purpose. To evaluate the regeneration of an infected skin wound in experimental steroid hyperglycemia in rats.Materials and methods. Regeneration of an infected rat skin wound (n = 30) was evaluated on the background of steroid hyperglycemia. Depending on the type of wound surface treatment, all observed animals were divided into 3 groups: the first group (n = 10) was treated with an ointment containing Cymbopogon proximus per os administration; the second group (n = 10) was treated with an ointment containing sodium fusidate 2 %; the third group (n = 10, control) the wound was treated with vaseline. After five days, local changes in the wound area and the activity of its regeneration were evaluated. We also studied the blood changes: the composition of the shaped elements and the content of total protein, albumins, transaminase activity (ALT, AST), total cholesterol, urea and creatinine.Results. The use of Cymbopogon proximus orally by rats of the first group, with induced diabetes mellitus, contributes to a decrease in serum glucose levels by almost two times compared with the second and third groups. Ointment containing Cymbopogon proximus has immunomodulatory properties: it prevents the development of leukopenia, promotes the activation of agranular immunocytes. The use of Cymbopogon proximus extract has a positive effect on the rate of wound regeneration due to several factors: reduction of hyperemia and edema, stimulation of leukocyte activity, and as a consequence activation of regeneration. We did not find a significant difference in the rate of wound regeneration when treated with an ointment based on Cymbopogon proximus extract and an ointment containing sodium fusidate (p > 0.05).Conclusion. The regeneration activity of an infected wound in rats with steroid hyperglycemia does not significantly differ when treated with antimicrobial ointment and Cymbopogon proximus. The extract of Cymbopogon proximus has a double effect in vivo: it reduces glucose levels and promotes wound healing in the condition of hyperglycemia, which is promising in the treatment of complications in diabetes mellitus.
