- Irritant / corrosive response data:
- The individual scores for erythema, oedema, haemorrhage and necrosis are given in remarks on results including tables and figures.
- Other effects:
- Subcutaneous heamorrhage appeared after 3 minutes; brown metachromatic changes macroscopically judged to be necrosis emerged after 5 minutes. These changes showed highly necrotic appearance after 60 minutes; namely, the dark red-brown skin surfaces were slightly dried and hardened. Four hours after application, the cut surfaces showed necrosis throughout the entire dermal layers and severe heamorrhage reached the dorsal muscle.
