毒性 | A toxin contained in the ovary and liver of puffer fish, in the eggs of the California newt and in some other animals. It is used as a chemical tool for the study of ion channels. The s.c. LD50 in mice is 10 mg/kg. It is a toxicant of nerve and muscle by blocking sodium channels, this action causing nerve and muscle paralysis. Symptoms include weakening of voluntary muscles, respiratory failure from paralysis of the diaphragm and hypotension. There is no antidote. Therapy involves artificial respiration. |
