Other effects:
One animal showed very slight (grade 1) erythema at about 1 hour, 1 day and 2 days after removal of the dressing. Grade 1 oedema was observed at about 1 hour in the same animal.
Staining of the skin occurred in the other two animals, but did not obscure the reading of the application sites.
