为进一步确定烟碱对大鼠心脏的作用，对描记烟碱作用后大鼠心电图进行分析，发现烟碱能引起大鼠心电图显示较长的QT间期，增加了PR间期及T波面积，与肾上腺素或去甲肾上腺素引起的QT间期延长相似，且能被M受体阻断剂阿托品所阻断，说明烟碱能够诱导局部释放乙酰胆碱或者作用于部分副交感神经控制的毒蕈碱受体。

In order to develop a safe and effective immunoadjuvant to enhance the immunity and resistance of animals against infection, a novel CpG Oligodeoxynucleotides containing 11 CpG motifs was synthesized and inserted into the VR1012 plasmid, designated as VR1C. Then the recombinant VR1C was entrapped with Chitosan nanoparticles prepared by the method of ionic cross linkage, and employed to inject muscularly 3-weeks old Kunming mice; the blank VR1012 packed with CNP and saline were used to inoculate mice as the control groups. 28 days after inoculation, all mice were orally fed with 0.4ml 2x108CFU/ per mouse virulent hemorrhagic enteritis E. coli to challenge the resistance against infection.

BmK IT2 is worthy of being considered to be a kind of new algesia peptide drug.

BmK粗毒和BmK I诱导的大鼠脊髓背角氨基酸类神经递质的释放采用微透析采样与高效液相色谱荧光检测技术，分析BmK粗毒和其主要致死成分BmK I诱发炎症痛过程中同侧脊髓背角氨基酸含量的动态变化。

The local injection of trypsin can be used in clinical practice as a new and effective therapy for snakebite.Our experiments indicate that when a lethal dose of crotalinae snake venom was injected into mice subcutaneously, survival rate increased significantly if a dose of trypin had been injected locally and promptly.

本文提供了一种局部注射胰蛋白酶治疗蛇伤的方法，在给小白鼠皮下注射致死剂量的竹叶青蛇毒后，立即注射胰蛋白酶可提高存活率68％，注射蝮蛇毒后，立即注射胰蛋白酶可提高存活率67％，注射尖吻蝮蛇毒后立即注射胰蛋白酶可提高存活率57％。

Endplate potentials, acetylcholine potentials, and electrotonic potentials were recorded from the motor endplates of isolated diaphragms from acute late septic and nonseptic rats.
