Test animals

Species:
rabbit
Strain:
New Zealand White
Details on test animals or test system and environmental conditions:
rabbits were 12 - 16 weeks old, with a weight of 2.24 - 2.60 kg, and kept in individual cages.
The animals rooms had 15 cycles of air per hour, a temperature of 18-23 °C, and a relative humidity of 45 - 55 %.
A 12hour dark/light cycle was applied.

Test system

Type of coverage:
semiocclusive
Preparation of test site:
shaved
Vehicle:
water
Controls:
not required
Amount / concentration applied:
0.4 gm in 1 ml of water
Duration of treatment / exposure:
4 hours
Observation period:
72 hours
Number of animals:
3
Details on study design:
animals were shave on the back, and TGIC suspension was applied on an area of 2 x 2 cm, and covered with a semi-occlusive bandage for 4 hours. Reading was at 4, 24, 48, and 72 hours.
Body weight was measured daily
