Abstract

This article considers the wound-healing effect of a hydrogel based on polyhexamethyleneguanidine hydrochloride under conditions of thermal shock modeling. The presence of gelling properties in combination with the high biocidal activity of polyguanidins opens the prospect of obtaining an effective single-component external agent, which is very important for antimicrobial chemotherapy of wounds and burns, as in their treatment there is a high probability of infecting the wound with microorganisms causing various infectious diseases. Previously, we developed a method for the preparation of a hydrogel based on polyhexamethyleneguanidine hydrochloride, which involves the cross-linking of the amino-end groups of the branched polymer with formaldehyde, resulting in a cross-linked polymer, which is a lump-like mass. The mechanical treatment of the hydrogel makes it possible to give the material an ointment form that is convenient for application to the skin. An experiment on the evaluation of the wound healing action of hydrogel was carried out under the conditions of modeling a thermal burn. The comparative preparation was multicomponent gel "Levomekol", in which polyethylene oxide was used as the basis. It was established that the hydrogel activates the growth of antioxidants and leukocytes in the blood of animals in dynamics on the 10th, 17th and 24th day of the experiment, amounting to 56.4 %, 33.8 % and 20.9 %, and of leukocytes - 27.7 %, 19.6 %; 6,2 % in relation to the norm. The method of contrast radiography of penetrating wounds showed that the daily reduction in the wound area is most pronounced in the hydrogel group, which indicates a pronounced reparative effect.

Summary

ГИДРОХЛОРИДА ПРИ ОЖОГАХ

В последние десятилетия было разработано множество материалов медицинского назначения на основе полимеров. Особое место среди них занимают гидрогели, перспективные для применения в качестве матрицносителей лекарственных средств. Однако чаще всего гелеобразующие полимеры не имеют собственной антимикробной активности, что ограничивает их использование только в качестве носителя. Установлено, что гидрогель оказывает влияние на течение раневого процесса, о чём свидетельствуют результаты вульнографии, показавшие, что суточное уменьшение площади раны в наибольшей степени выражено у группы «гидрогель», что также свидетельствует о выраженном репаративном действии. Определено, что при ожоге наблюдается резкое уменьшение суммарного содержания антиоксидантов и нарастание количества лейкоцитов. На модели линейной кожно-мышечной раны и термического ожога установлено выраженное ранозаживляющее действие гидрогеля, о чём свидетельствуют результаты ранотензометрии, вульнографии и патоморфологических исследований. Что гидрогель оказывает влияние на содержание в крови антиоксидантов и лейкоцитов, способствуя нормализации их количества. Ключевые слова: полигексаметиленгуанидин гидрохлорид, гидрогель, ожоги, ранозаживляющее действие
