" Strychnine: Organic compound, a poisonous alkaloid obtained from seeds of the nux vomica tree of India and related plants of the genus Strychnos."

有机化学物，含毒生物碱，提取自印度马钱子树以及其它相关的马钱属植物种子。

" Strychnine: Organic compound, a poisonous alkaloid obtained from seed s of the nux vomica tree of India and related plants of the genus Strychnos."

有机化学物，含毒生物碱，提取自印度马钱子树以及其它相关的马钱属植物种子。

By pretreatment of picrotoxin (30 μmol/L) and strychnine (1.0 μmol/L), inhibitory amino acid receptor antagonists, the potentiation of cVLF-EPSPs by TRH was kept effective in 3 MNs.

使用印防己毒素(30μmol/L)和士的宁(1.0μmol/L)阻断抑制性氨基酸受体后，灌流TRH(0.2μmol/L)15min仍然在3个MN呈现了易化cVLF-EPSP的作用。

The effects of FC were abolished by intrathecal administration of kynurenic acid (50 nmol) or 2-amino-5-phosphonovaleric acid (AP-5, 0.5 nmol), but not by 6, 7-dinitroquinoxaline-2, 3-dione (DNQX, 5 nmol), picrotoxin (5 nmol) or strychnine (1 nmol).

，高频刺激前0.5小时鞘内注射特异性NMDA受体拮抗剂AP-5（0.5 nmol）或非选择性谷氨酸受体拮抗剂犬尿酸（50 nmol），FC的效应被阻断；non-NMDA受体拮抗剂DNQX（5 nmol）不能阻断FC的效应；〓（5 nmol）和甘氨酸受体（1 nmol）拮抗剂对FC的效应也无明显影响。

Results: Among 32 tested MNs, depolarizing responses(excitatory postsynaptic potential, EPSP) were elicited by cVLF stimulation in 21 MNs, hyperpolarizing response (inhibitory postsynaptic potential, IPSP) in 1 MN, and IPSP preceded by EPSP in 4 MNs. The cVLFEPSPs were stimulus intensity-dependent, and could be abolished by low Ca(superscript 2+)/high Mg(superscript 2+) solution. compared with iVLF-EPSPs, cVLF-EPSPs showed longer latency (P.001). The cVLF-IPSP presented with membrane potential-dependent property and was eliminated by the perfusion of picrotoxin (30 μmol/L) and strychnine (1.0 μmol/L).

结果：在32个测试的MNs，观察到cVLF电刺激可在21个MNs上诱发去极化反应（即cVLF性兴奋性突触后电位，cVLF-EPSP），在1个MN上诱发超极化反应（即cVLF性抑制性突触后电位，cVLF-IPSP），在4个MNs上诱发cVLF-EPSP后复合有cVLF-IPSP的反应。cVLF-EPSP具有刺激强度依赖性、被低钙高镁溶液取消的特性，与i VLF性EPSP相比，有潜伏期较长的特点(P.001)。cVLF-IPSP呈膜电位依赖性，并被印防己毒素(30μmol/L)及士的宁(1.0μmol/L)取消。

Propofol induced Cl- currents at concentrations of 10-5 and10-4 M, which were sensitive to picrotoxin and, to a lesserextent, to strychnine. Propofol (10-6 M) enhanced -aminobutyricacidA (GABAA; 10-6 M)-induced current synergistically. Moreover,propofol (10-5 and 10-4 M) significantly increased the decaytime of evoked-inhibitory postsynaptic currents, which suggestsa postsynaptic modulation of GABAA receptors.

异丙酚在浓度10-5~10-4M 时，産生 Cl-电流，对印防己毒素敏感，在更小浓度范围内，对番木鼈碱敏感。10-6M 的异丙酚加强 GABAA 産生的电流，另外，异丙酚（10-5、10-4M ）显著地增加了突触后诱发-抑制电流的衰退时间，提示了 GABAA 受体的突触后调节作用。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
