From this dose, in the main test, series doses were contributed to series animal groups to measure LD50. Toxic symptoms or deaths in amimals were observed within 72 hours. Results: In the limited test, at dose 5000mg/kg, both animals were not dead with 72 hours. In the main test, within 72 hours, toxic symptoms or deaths in animals were not found. Body weights of all animals were not decreased. Histological images of livers and kidneys in all animals were normal at all series doses including 500mg/kg, 1000mg/kg, 2000mg/kg and 5000mg/kg.
