  1. Estimation of local vital reactions in severely burned tissues of guinea pig skin using C3a or C3a desArg as a marker.

    Article - En anglais

    We observed changes in levels of anaphylatoxin C3a and/or its desArg (C3a/C3a desArg) peptides in the local site of severely burned skin tissues of guinea pigs using immuno-Western blotting methods.

    The C3a/C3a desArg peptides, which were probably generated during complement activation, were detected at significant levels from 30 min to 72 h following burn injury in an area limited to 5 mm from the wound edge.

    Levels of these peptides showed a tendency to be highest in that area 24 h after burn infliction.

    In postmortem injuries, C3a/C3a desArg peptides could not be detected.

    These peptides were detected in antemortem wounds up to at least 2 days at 22oC and up to 5 days at 4oC after death, although decreases in levels were found.
