Abstract

Abstract: Suppressive effect of bis (3-amino-2-pyridine) diselenide (BAPD) on psychiatric disorders – atopic dermatitis (AD) comorbidity in mice was investigated. To sensitize the animals, 2, 4-dinitrochlorobenzene (DNCB) was applied to their dorsal skin on days 1–3. Mice were challenged with DNCB on their ears and dorsal skin on days 14, 17, 20, 23, 26, and 29. BAPD and Dexamethasone were administered to the animals, from days 14–29, and skin severity scores and behavioral tests were determined. Oxidative stress and inflammatory parameters were evaluated on the dorsal skin of mice. Na +, K + -ATPase activity and corticosterone levels were determined in hippocampus/cerebral cortex and plasma of mice, respectively. BAPD improved cutaneous damage, scratching behavior, inflammatory and oxidative stress markers. BAPD showed anxiolytic- and antidepressant-like effects and restored Na +, K + -ATPase activity and corticosterone levels. The present study was performed using female mice due the susceptibility for this disease. But, the evaluation of AD model in male mice would help to verify whether the male gender has the same predisposition to present this pathology. Our data demonstrated the suppressive effect of BAPD on psychiatric disorders – AD comorbidity by regulating inflammatory and oxidative status in mice.

The oxidative stress induced by DNCB was reduced by BAPD. The efficacy of BAPD was similar or superior to Dexamethasone.
