毒理性

• 毒性总结

Lolitrem B的神经学效应是由于其能够抑制大电导钙激活钾通道（BK通道）。Lolitrem B与BK通道的alpha亚单位结合，抑制通道的钾电流。这通过直接作用于肌肉中的通道或通过作用于中枢神经系统中的通道产生震颤效应。（A3066, A3067）

The neurological effects of Lolitrem B are a result of its ability to inhibit large conductance calcium-activated potassium channels (BK channels). Lolitrem B binds to the alpha subunit of the BK channel, inhibiting channel potassium currents. This causes tremorgenic effects either by directly affecting channels in the muscle or by acting on channels in the central nervous system. (A3066, A3067)

• 健康影响

震颤素类真菌毒素影响中枢神经系统活动。它们会导致牛患上一种被称为“摇摆综合症”或“黑麦草摇摆病”的神经系统疾病。

Tremorgenic mycotoxins affect central nervous system activity. They cause a neurological disease of cattle known as "staggers syndrome" or “ryegrass staggers”. (A2976, A3066)

毒理性

• 症状

震颤素类真菌毒素影响中枢神经系统活动，引起包括精神混乱、瘫痪、震颤、惊厥和死亡在内的神经症状。它们会导致牛患有一种称为“摇摆综合症”或“黑麦草摇摆病”的神经疾病，其特征是运动协调障碍、肌肉震颤、过度兴奋、惊厥和共济失调。其他症状包括血压升高、心率和呼吸率增加。尽管lolitrem B的神经毒性效果持续时间较长，但它们也是可逆的。（A2976, A3066, A3067, A3068）

Tremorgenic mycotoxins affect central nervous system activity, inducing neurologic symptoms including mental confusion, paralysis, tremors, seizures, and death. They cause a neurological disease of cattle known as "staggers syndrome" or “ryegrass staggers”, which is characterized by impaired motor coordination, muscle tremors, hyperexcitability, convulsions, and ataxia. Additional symptoms include increased blood pressure, heart rate and respiration rate. While the neurotoxic effects of lolitrem B have a long duration, they are also reversible.
