Abstract

Objectives: Atopic dermatitis (AD) is an easily recurrent inflammatory skin disease. Since AD has complex pathology, people have been investigating it on different aspects with various experimental models. One of them is in vivo model which has spontaneously developed AD-like skin lesions by various inducers. Methods: In this study, two kinds of mouse species were applied in the experiment; BALB/c and C57BL/6 mice. We compared features among the animal species making AD mouse model with protein allergen, ovalbumin. AD-like skin lesions were induced by ovalbumin on two kinds of scheme and were evaluated with the histological results and size of spleen which is a critical immunological organ. Also, we measured the level of immunoglobulin E in serum. In addition, we investigated the results of ovalbumin induced-AD-like skin lesions along with obesity. Results and Conclusion: We evaluated weight of organs and thickness of epidermis. These results suggest the possibility of the appropriate in vivo experimental model for AD or the comorbidity with obesity.
