안전 및 규제
| Treatment | To control severe tremors caused by tremorgenic mycotoxins, methocarbamol should be administered. Generalized seizures may be treated with diazepam followed by methocarbamol or a barbiturate such as pentobarbital sodium. Gastric lavage should be performed and activated charcoal administered to limit further absorption of toxins. (A744) |

| 건강 영향 | Tremorgenic mycotoxins affect central nervous system activity. They cause a neurological disease of horses and cattle known as "staggers syndrome". Penitrem A is also genotoxic and causes DNA damage. (A2974, A3026) |
| 노출 경로 | Oral, dermal, inhalation, and parenteral (contaminated drugs). (A3101) |
| 독성 요약 | Tremorgenic mycotoxins exert their toxic effects by interfering with neurotransmitter release, possibly by causing degeneration of nerve terminals. They are thought to inhibit gamma-aminobutyric acid (GABA) receptors, both pre- and postsynaptic, as well as inhibit transmitter breakdown at the GABA-T receptors. This would initially increase neurotransmitter levels, potentiating the GABA-induced chloride current, then lead to decreased levels of neurotransmitter in the synapse. Penitrem A is also know to increase the spontaneous release of the neurotransmitters glutamate and aspartate from cerebrocortical synaptosomes. In addition, it inhibits presynaptic high-conductance Ca+2 activated maxi-K+ channels in the smooth muscle. Penitrem A is also genotoxic and causes DNA damage. (A2976, A2991, A2993, A3026) |
| Signs and Symptoms | Penitrem A causes an tremorgenic syndrom consisting of acute tremor followed by chronic ataxia. Other symptoms include severe muscle fasciculations, vomiting, convulsions, tachycardia, and seizures, possibly leading to massive liver necrosis and death. Tremorgenic mycotoxins cause a neurological disease of cattle known as "staggers syndrome", which is characterized by muscle tremors and hyperexcitability. (A2974, L1959, A2989, A2990) |
