Abstract
Increased vascular permeability, as measured by changes in skin weight and Evans blue dye extravasation, was produced in the skin after immersion of the anesthetized rat's paw in 12 N hydrochloric, 18N sulfuric, or 14N hydrofluoric acids for 2 min. Corticotropin-releasing factor (CRF), a 41-residue peptide having the rat/human sequence, injected 28 üg/kg i.v. 10 min before immersion, was efficacious in reducing these indices of skin injury.
