TNF and Schnyder corneal dystrophy: To evaluate the effects of intracellular cGMP modulation on leukocyte recruitment, we administered hydroxyurea (100 mg/kg, i.v.), BAY 60-2770 (10 μg/mouse, i.v.), and/or BAY 41-2272 (10 μg/mouse, i.v.)to chimeric SCD mice immediately before inducing leukocyte recruitment with TNF (0.5 μg, i.p.).
