To study the 3, 4- dinitro-furazan-based oxidation furazan (DNTF) of sub-acute toxicity and chronic toxicity, to determine the acute toxicity classification DNTF, the nature of toxic effects and major target organ for the development provide the basis for occupational exposure limits.


( 1) Acute toxicity: The oral gavage method once infected, symptoms of poisoning of animals observed to calculate the LD50DNTF and 95% confidence limits. ( 2) sub-chronic experiment: selection of 96 healthy SD rats were randomly divided into four groups, doses of 25, 56.2, 125 mg/kg and the negative control group, Exposure for ninety days,five days a week, once a day, The rats were killed at end of Exposure, heart, liver, spleen, lung, kidney, brain,testis, uterus were taken to observe the pathological changes.


( 1) Acute oral toxicity test results indicate that DNTF rat oral LD50 greater than 5000 mg/kg, DNTF mice treated by oral LD50 4589 mg/kg, 95%confidence limit for the 4026-5230 mg/kg, Acute toxicity grade level is low toxicity compounds. (2) Sub-chronic toxicity experiment, the high-dose male rats, high, medium and low-dose group female rats weight gain than the negative control group, compared with the control group, the difference was statistically significant (P<0.05).125 mg/kg of serum alanine aminotransferase, aspartate aminotransferase was significantly higher. 125 mg/kg dose groups, liver, kidney, lung, testicular factor was significantly higher. Liver, kidney, lung histological examination showed obvious morphological changes.


Acute toxicity grade DNTF low toxicity level compounds, target organ toxicity of liver, kidney and lung.
