The purpose of this study was detection of the poison from the acute cyanide and arsenic poisoned rabbits. The author administered KCN and AS2 03 to rabbits and caused acute poisoning, then analysed the teeth, dental pulp and jaws of the rabbits chemicotoxicologically and observed the specimen histopathologically. 1. In subcutaneously injected group of KCN, a large amount of cyanide was detected
in blood and lung and a small amount of cyanide was detected in teeth and dental
pulp, but was not detected in jaws:
2. In orally administered group of 1CCN, a large amount of cyanide was detected in blood, lung and dental pulp and a small amount of ´cyanide was detected in teeth and jaws.
3. In orally administered group of AS203, arsenic was detected markedly in teeth and jaws, but was detected a little in dental pulp.
4. In orally administered and heat-treated group of KCN, the author could detected cyanide in teeth, dental pulp and jaws.
5. In subcutaneously injected group of KCN, orally administered group of KCN and orally administered group of AS2 03, histopathologic findings showed the congestion and hemorrhage in dental pulp. .
6. In orally administered group of AS203, the congestion and hemorrhage in buccal mucosa were found and the basal cell degeneration and fibrosis were found in palatal mucosa.
