Abstract

From childhood, human skin is exposed to external environmental factors that cause adverse effects on skin cells and their structure (Arjmandi, Faraz, Mortazavi, Gh., Mortazavi, S. A. R., Zarei, 2018Over time, skin changes become more related not to genetic predisposition but to environmental interactions. Therefore, deterioration of skin condition is thought to be directly related to lifestyle. And more recently, due to the modern lifestyle, new technologies, the skin is inevitably exposed to oxidative stress (Michniak-Kohn, Monteiro e Silva, Leonardi, 2017). External antioxidants such as resveratrol, quercytin, vitamin C, glutathione, and others are extracted from a variety of sources and have unique, skinprotecting and restorative properties that affect the fight against free radicals (Jiang, Mazur, McDaniel, Nelson, Yaroshinsky, Stephens, Waugh, Wortzman, 2019).

Abstract

Tyrimo tikslas - išanalizuoti skirtingų kosmetikos priemonių su antioksidantais poveikį oksidacinio streso paveiktai veido odai. Oksidacinis stresas – reiškinys, kuris atsiranda dėl disbalanso tarp laisvųjų radikalų susidarymo ląstelėse ir antioksidantų gamybos sutrikimo organizme. Jį sukelia įvairūs išoriniai aplinkos veiksniai: UV spinduliai, mėlynoji šviesa, aplinkos užterštumas (kietosios dalelės, ozonas, CO2), rūkymas, mityba, miego režimas. O dėl šių veiksnių susidarę laisvieji radikalai pažeidžia odos ląsteles, sutrinka deguonies perdavimo procesai organizme ir skatina priešlaikinį senėjimą. Todėl atsižvelgus į tyrimo dalyvės veido odos būklę ir pagal išsikeltus kriterijus labiausiai tinka kosmetikos priemonės su šiomis veikliosiomis medžiagomis: 4 rūšių hialurono rūgšties derinys, vitaminas C, resveratrolis, alfa lipolinė rūgštis, ferulo rūgštis, niacinamidas, vitaminas E, bisabololis, raudonųjų dumblių ekstraktas, arabiškos medvilnės kamieninės ląstelės., Research aim - to analize the effect of different cosmetic products containing antioxidants on facial skin that has been exposed by oxidative stress. Oxidative stress is a phenomenon that occurs from the imbalance between the formation of free radicals in cells and the disorder in the production of antioxidants in the body. It is caused by various external environmental factors: UV rays, blue light, environmental pollution (particulate matter, ozone, CO2), smoking, diet, sleep. And the free radicals formed by these factors damage the skin cells, disrupt the oxygen transfer processes in the body and promote premature aging. Therefore, depending on the condition of the study participant facial skin and the criteria, cosmetics with the following active ingredients are the most suitable: a combination of 4 types of hyaluronic acid, vitamin C, resveratrol, alpha lipoic acid, ferulic acid, niacinamide, vitamin E, bisabolol, red algae extract, arabic cotton stem cells.

Abstract

The present study was conducted to investigate the effect of lead (Pb) and / or zinc (Zn) ions on the content of metallothionein (MT), reduced glutathione (GSH) and malondialdehyde (MDA) in mouse liver. Two weeks of mice intraperitoneal treatment with ZnSO4 and Pb(CH3COO)2 solutions, increased the content of MT by 25% and 55%, respectively. Mice pre-treatment with ZnSO4 for 20 min before Pb(CH3COO)2 injections, attenuated the effect of Pb2+ and partly reduced (by 30%) the increase of MT content in mice liver. Two weeks of administration with Pb(CH3COO)2 solution, induced the decrease of GSH content by 22% comparing to the control. Treatment with ZnSO4 didn't have any effect on the content of GSH. Pre-treatment with ZnSO4 for 20 min before Pb(CH3COO)2 injections decreased GSH content in mice liver by 48% as compared to the control group of mice. Neither Pb2+ nor Zn2- caused any remarkable alterations on MDA content in liver of mice. [ABSTRACT FROM AUTHOR]
