SCORING SYSTEM: according to Draize et al. (1959)
Score for skin irritation in rabbits
Erythema and eschar formation
No erythema 0
Very slight erythema (barely perceptible) 1
Well defined erythema 2
Moderate to severe erythema 3
Severe erythema (beet redness) to slight eschar
formation (injuries in depth) 4
Total possible erythema score 4
Edema formation
No edema 0
Very slight edema (barely perceptible) 1
Slight edema (edges of area well defined by
definite raising) 2
Moderate edema (raised approximately 1 mm) 3
Severe edema (raised more than 1 mm and
extending beyond area of exposure) 4
Total possible ederna score 4
Calculation of the primary skin irritation index:
primary irritation index = [erythema intact skin (24 h + 72 h) + erythema abranded skin (24 h + 72 h) + edema intact skin (24 h + 72 h) + edema abranded skin (24 h + 72 h) ]/4
Assessment of primary skin irritation index:
0 = none
>0 - 1 = minimal
>1 - 2 = slight
>2 - 4 = moderate
>4 - 6 = marked
>6 - 8 = extreme
