Each experimental animal was followed for 5 days per week for 30 days.Our findings revealed that GLU-induced dermatitis via the upregulation of TNF-α, IL-1b, NFkb 1, and ptgs2 mRNA expression and the downregulation of TGFB1 mRNA expression caused oxidative stress and altered the biochemical markers and histological appearance. Here, PTGS2 is linked to dermatitis.
