Some features of the mechanism of kainic acid neurotoxicity were tested after the injection of this substance in the optic tectum of goldfish. A systemic treatment with the N-methyl-D-aspartate (NMDA) receptor antagonist MK801 did not influence the degree of toxicity, assessed by a decrement of enzymatic neuronal markers; instead, a significant neuronal rescue was obtained after the abolition of the excitatory input from the torus longitudinalis to the tectum.
在金鱼视顶盖注射海藻酸后,对其神经毒性机制的一些特征进行了测试。用N-甲基-D-天冬氨酸(NMDA)受体拮抗剂MK801进行全身治疗,并不影响通过神经元酶标记物减少来评估的毒性程度;相反,在消除从纵纹隆起向视顶盖的兴奋性输入后,获得了显著的神经元保护作用。
