查询词典 clamp

In rats with 28-day high-fat feeding（59%carolries was provieded by nonsaturated fatty acid）,euglycemic-hyperinsulinemia clamp technique was performed in order to estimate their insulin sensitivity.

用富含不饱和脂肪酸的高脂肪饮食（脂肪提供59%的热量）喂养28天后，用正常血糖-高血浆胰岛素钳夹技术检测大鼠的胰岛素敏感性。

Sustained AF could be induced easily in all dogs during vagal nerve stimulation in vivo both before and after isolation of all PVs with encircling lesions created by a bipolar radiofrequency ablation clamp device. PV elimination had no effect on atrial effective refractory period or its responses to cholinergic stimulation. Autonomic ganglia were identified by bradycardic and/or tachycardic responses to high-frequency subthreshold local stimulation. Ablation of the autonomic ganglia overlying all PV ostia suppressed the effective refractory period-abbreviating and AF-promoting effects of cervical vagal stimulation, whereas ablation of only left- or right-sided PV ostial ganglia failed to suppress AF.

无论是在双极环状消融所有PV之前或之后，在体刺激颈迷走神经节过程中持续性房颤在所有犬均能轻易被诱导出，PV切除对心房肌的有效不应期或对胆碱的反应均没有影响，通过对高频的域下刺激发生快速或慢速反应来鉴定自主神经节，消融叠加于PV口部的自主神经节能抑制有效不应期的缩短、和刺激颈迷走神经诱发的房颤促进作用，而仅消融左或右侧PV口部的自主神经节却不能抑制房颤。

ABSTRACT:Objective To investigate the method of stably isolating pachyntic Spraque Dawley rat calcium tolerant ventricular myocytes for patch clamp techniques.

Whole-cellpatch-clamp technology demonstrated that VDPG (1g/L) had notsignificant effects on the delayed-rectified K~+ current, TTX-sensitive Na~+ current and high-voltage-activated Ca~(2+) current of rat dorsalroot ganglion cells. The fast transiet K~+ current of cottonbollworm dorsal DUM cells, the fast transiet K~+ current, Na~+ current andhigh-voltage-activated Ca~(2+) current of Periplaneta Americana dorsalunpaired median cells were also not significantly affected byVDPG at the same concentration. However, VDPG had significant effecton the fast transiet K~+ current of Pieris rapae. The VES had not significanteffects on the high-voltage-activated and low-voltage-activated Ca~(2+)current of rat DRG cells.

膜片钳电生理实验显示1g／L毒囊粗毒对蜚蠊DUM神经元的快瞬时钾电流、钠电流、高电压激活的钙电流，对棉铃虫快瞬时钾电流和大鼠DRG细胞延迟整流钾电流、TTX-S型钠电流、高电压激活的钙电流均无明显作用，却对菜青虫快瞬时钾电流有明显作用；电刺激粗毒对大鼠DRG细胞低电压和高电压激活的钙通道无明显作用。

We previously reported that unclamping of an abdominal aorticcross-clamp causes initial dilation of pial arteries followedby sustained constriction.

以前我们曾报导了腹主动脉阻断钳松夹可引起软脑膜内动脉先扩张随后持续收缩。
