Nevertheless, in place of 600 mOsm, 450 mOsm osmotic tension was applied to measure intracellular calcium concentration, in order to examine the protective effects of polyols, with the elimination of cell death. In line with our pilot study, 450 mOsm hyperosmotic stimulus with sorbitol was sufficient to induce a short elevation of intracellular Ca2 with a kinetics equivalent to that of measured by Dascalu et al who applied 500 mOsm sucrose.six While the exact molecular mechanism continues to be not completely clarified, it has been de., followed by Dunn's approach (median, 25th and 75th percentile), p0.05 vs Contr, n=3 (d) In spite of the difference within the statistical tests, mean SD values are shown in all subfigures for uniform presentation.

Therefore, the present study aimed at the investigation of osmotic challenge potentially accompanying ICD. In response to hyperosmotic pressure, organic osmolytes are accumulated by the cells. Within the skin, betaine, myoinositol and taurine are important osmolytes and also the expression of their transporters (betaineGABA transporter, sodiummyoinositol transporter and taurine transporter) is induced by osmotic tension.25 The anti-irritant and anti-inflammatory effects of glycerol and xylitol have already been demonstrated in animal experiments.17 Joint application of glycerol and xylitolincreases skin hydration, decreases TEWL, improves biomechanical properties from the skin and induces a larger filaggrin production inside the epidermis after two weeks of application.18 Having said that, their cellular mechanism of action has not been revealed in facts. We assumed that these polyols may act as organic osmolytes and consequently might have a function in osmoregulation. It has been described that the effects of polyols may perhaps rely on the applied concentration.17,26 Hence, two different concentrations were tested in our in vivo studies16,17 as well as two different concentrations were chosen for the present experiments, according to previous in vitro outcomes.21 Accordingsubmit your manuscript | www.dovepress.comClinical, Cosmetic and Investigational Dermatology 2019:DovePress0.27 gly0.45 xyl0.45 xyl0.45 xyl0.45 xylContr.Contr.0.27 gly0.45 xyl0.45 xylContr.Contr.DovepressSz et alto the outcomes with the effect of polyols on Ca2 concentration in our preliminary experiments, only the greater polyol concentrations have been applied in the measurement of cellular viability, cytotoxicity and cytokine expression. In an effort to induce osmotic tension, as an alternative to the ionic sodium chloride and the detergent SLS, sorbitol was selected, which is a metabolically inactive, inert agent.
