Beneficial Effects of Liposome Containing Arthrocen (ROCEN)) on Atopic Dermatitis in Mice

Objective: Atopic dermatitis (AD) is a chronic inflammatory skin disease caused mainly by the immune stimulus. The current study aimed to investigate the effects of liposome containing arthrocen (ROCEN) and its comparison with betamethasone (Beta) on mice subjected to AD. Methods: First of all, the risk assessment of ROCEN sensitization was done, then mice were subjected to oxazolone (Oxa) for chronic AD induction and treatment. Scratching and wiping behaviors related to dermatitis were evaluated in animals treated topically with ROCEN. The histological and immunohistochemistry analysis of interleukin-8 (IL-8) and tumor necrosis factor-α (TNF-α) were conducted to the dorsal skin of treated rats. Results: The results showed that cutaneous administration of ROCEN on sensitized mice for 5 weeks, alleviated significantly scratching and wiping symptoms, erythema, scaling, and edema in animals’ skin. Moreover, histological indices showed that ROCEN reduced effectively leucocyte infiltration and improved skin healing parameters in AD mice. Immunohistochemically markers of IL-8 and TNF-α were hindered significantly by ROCEN in dermal tissues of mice. Conclusion: ROCEN potentiated alleviation of the AD symptoms rather than betamethasone drug in an experimental model.
