Carboxymethyl Glucan was used in the pretreatment for protecting culture cells against oxidative stress before exposing to UVA radiation at a dose rate of 300Wm-2 for different time periods. The contents of GSH and ferritin were determined by enzymatic assay immediately after UV radiation and 24 hours at 100 ug/mL, CM-glucan clearly showed protective effects against oxidative stress induced by UVA radiation.
The formulation of CM-glucan at various concentrations(0.04-0.4%) of hydrogel and oil in water emulsion were used as a pretreatment on five volunteers' forearms for evaluation of skin humidity protective effects caused by a challenge with 10% sodium dodecyl sulfate over a period of 2 weeks. All formulations enhanced the skin humidity compared to the untreated skin. The protective effects against the skin humidity reduction depends on the CM glucan concentration.
The renewal rate of the stratum corneum was determined by the gradual diminution of a fluorescence set at the onset of the experiment by dansyl chloride. 0.4% CM glucan in emulsion enhanced renewal rate of the stratum corneum more than 30% compared with untreated skin.
Skin of volunteers were pretreated for 5 days with oil-in-water emulsions containing different concentrations of CMG. Then the skin were exposed to UV-A. Squalene hydroperoxides concentrations were measured in chemiluminescenc units after lipid extractions from irradiated skin.
