Abstract

Selon l'invention, des facteurs peptidiques isolés d'une peau ayant subi une lésion chimique ou thermique et le traitement au moyen de préparations d'iodine peuvent réduire ou soigner l'extension de la blessure lorsque respectivement on les administre ou on les applique à d'autres animaux. Des peptides spécifiques, notamment des fragments d'histone H2A et de fibrinopeptide A, et des dérivés de ces peptides utilisés de préférence sont décrits, ainsi que des compositions pharmaceutiques et des procédés d'utilisation de ces peptides. Selon l'invention, les extraits, les peptides et les compositions pharmaceutiques sont utiles dans la prévention et dans le traitement d'états pathologiques inflammatoires et d'une exposition à des stimuli nocifs.
