Abstract : [Summary] The experiment was conducted on rats in order to clarify the acute and subacute toxicity of silver ammonium fluoride, which has an excellent pharmacological effect for the treatment of hypersensitive dentine and the prevention of carious. For acute toxicity, the lethal dose was examined after oral subcutaneous and intraperitoneal administrations. In case of subcute toxicity, body weight, urine, blood and wet organic weight were examined. The result of the above experiments are summarrized as follows: 1) After high dose of the drug administraion, a marked ptosis, nasal discharge, intestinal hemorrhage, and hypertrophy of liver were odserved. However, all the reflexes were remained intact until the death. The LD50 was 57mg/100g for male, and 54mg/100g for female after oral administration; 34mg/100g for male, and 35mg/100g for female following sudcutaneous injection, and 9.6mg/100g for male, and 10.0mg/100g for female after intraperitoneal injection. 2) After 30 days of oral administaration, the body weight was decreased in proportion to increase of dosage. The urine, blood, and wet organic weight were not altered, however, gastric wall found to be thinned.
