Systemic effect of the antioxidant gel in experimental dermatologic pathology / E. Vazhnichaya, O. Baliuk, A. Sydorenko // EC Pharmacology and Toxicology. – 2024. – Vol. 12, issue 12. – Р. 1–9.https://repository.pdmu.edu.ua/handle/123456789/25493Many dermatological diseases are accompanied by oxidative stress and natural antioxidants are used in dermatology and cosmetology. The efforts to use synthetic antioxidants for skin care and treatment are practically absent. That is why we select for this investigation new topical formulation of ethylmethylhydroxypyridine succinate (EMHPS), a synthetic antioxidant. The objective is to study the status of lipid peroxidation and antioxidant protection in the blood of animals with experimental dermatologic pathology under the influence of the EMHPS gel topical use. There were three series of experiments on 125 adults male Wistar rats with chemical depilation, acute ultraviolet skin damage and psoriatic-like dermatitis. The 5% EMHPS gel was applied to the skin in a dose of 125 mg/kg. The duration of treatment was 21 days after chemical depilation, 3 days after ultraviolet irradiation, and 6 days after the induction of imiquimod dermatitis. The animals were euthanized in different moments of the experiments and the malondialdehyde (MDA) concentration, superoxide dismutase (SOD) and catalase activities were determined in the blood. The data were statistically processed by ANOVA method with a post-hoc Tukey test.enoxidative stressantioxidantethylmethylhydroxypyridine succinategelskin disease animal modelsystemic effectArticle
