Square brackets numbered 1 (red) and 2 indicate ear thickness (dermis and epidermis increase, respectively), and arrow numbered 3 (right down) and 4 (right) indicate inflammatory cells (infiltration of mononuclear leukocytes) and blood vessel (vasodilatation), respectively. The bar represents 100 µm.
