The present study was designed to investigate whether histamine is involved in the protective effect of carnosine on Aβ42-induced impairment in differentiated PC12 cells.

因此本实验的主要目的是检测肌肽对Aβ42诱导的神经兴奋性损伤是否具有保护作用，肌肽-组胺酸-组胺通路是否参与其保护机制，谷氨酸含量，NMDA受体表达及功能在这一过程中是否受到影响，最终阐明肌肽保护作用的具体机制。

The results obtained suggest that PTK within the NTS regulates the peripheral chemoreflex control of respiration and that this regulation of PTK may be mediated through the phosphorylation of AMPA receptors in NTS neurons.

结果提示，NTS处的蛋白酪氨酸激酶对外周化学感受性反射具有一定的调节作用，并且NTS处磷酸化修饰AMPA受体可能是PTK发挥这种调节作用的途径之一。

Objective To evaluate the protective effect of the classic antioxydant VitC on crystallin in vitro and to establish a set of criterion used in design, test and screen of anticataractous drugs.

In this experiment, the combination of common needling and electro-stimulation in electropuncture group improved symptoms more than manual-needling group, which may be due to the change ofβ-EP level.

本实验电针治疗组以普通针刺与电刺激的有机结合，其改善作用明显强于手针组，β-EP水平的变化可能是其作用的一个方面。

Electropuncture not only can improve damaged symptoms of peripheral nerve but also relieve pain by stimulating central nerves, which may be the cause why electropuncture had better effect on enhancing mechanical pain threshold of rats operated side.

电针不仅可以改善外周神经的损伤症状，同时还通过刺激中枢神经的机制达到镇痛作用，此模型中大鼠术侧机械痛阈改善方面电针优于单纯针刺，这可能就是电针作用的一个方面。

In contrast to fungicidal activity of PEI alone, larger sized PEI resulted in a higher synergistic effect when combining with the conventional antimicrobial agents.

与单独作用的PEI相比，分子量较大的PEI与常规药物联合使用时可产生较强的协同作用。

Gliosis plays a critical role in post-traumatic epileptogenesis. The inhibition of the proliferation of astrocytes with 7β OHCH could influence synaptic plasticity, modulate the imbalance of excitatory and inhibitory systems in hippocampus and postpone the latency between injury and the occurrence of chronic spontaneous seizures, furthermore to some extent, reduce the occurrence of post-traumatic epilepsy.

星形胶质细胞增生在创伤性癫痫发病机制中起重要作用，抑制胶质细胞增生，可影响海马突触可塑性，有利于调整海马内兴奋性和抑制性功能系统之间作用的失衡，可延长损伤与发生慢性自发性抽搐之间的间歇期，在一定程度上降低创伤性癫痫的发病率。
