Acute inflammatory response of the rat pawskin to acid injury is attenuated by corticotropin-releasing factor.

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 micrograms/kg i.v. 10 min before immersion, was efficacious in reducing these indices of skin injury.
