Effect of time-dependent NM exposure on the cutaneous toxicity and clinical sequelae of injury progression in SKH-1 hairless (A) and C57BL/6 (B) mice.

<p>Dorsal skin of mice was exposed topically to either 200 µL of acetone or NM (3.2 mg) in 200 µL acetone, and animals were observed for NM-induced clinical effects/lesions on exposed skin tissue. Pictures were taken and the visible injury lesions were compared between SKH-1 hairless (A) and C57BL/6 (B) mice. VC, vehicle control.
