RS-Freetext:
MORTALITY: No deaths occurred during the experiment.
CLINICAL SIGNS: 3/6 animals gained weight during the 14 days
the experiment lasted.  3/6 animals lost weight or did not
gain weight. Well-defined to severe erythema and slight to
severe oedema were observed in all six animals at the
24-hour dermal observations. The severity of the lesions did
not vary significantly between the animals with abraded or
non-abraded skin.  Lethargy and hypernea were observed in
each animal during the first 24 hrs following compound
administration.
NECROPSY FINDINGS: Not reported.
