Abstract:The human body is constantly exposed to the risk of traumatic lesions. ROQUETTE Schizochytrium
sp. (SCs) is a marine microalgae containing large amounts of health-valuable nutrients, more particularly
polyunsaturated fatty acids such as docosahexaenoic acid. SCs was investigated by oral administration
(125, 250 and 500 mg/kg) and cutaneous application (2.5, 5.0 and 10.0%) to evaluate its impact in two
dermatological disorder models in mice: skin inflammation and wound healing. For skin inflammation, it
was administered during 14 days starting one week before the induction of chronic skin inflammation by repeated cutaneous
application of 12-O-tetradecanoylphorbol 13-acetate (TPA). For wound healing the microalgae was administered after
incisional wound healing of the skin until complete wound healing. Results indicated that oral and topical administrations
of the two higher doses of SCs had significant effects on macroscopic score of skin inflammation. It had also efficient effect
on healing process and duration of wound healing with a dose-response by oral administration and a maximal effect
observed from the lowest to the highest dose by topical application. These findings suggest that administration of SCs by
both oral and topical routes appeared to have beneficial effects on skin lesions.
