豚鼠

Methods Animals were randomly and equally divided into five groups: saline control group, positive drug control group, low-dose, medium-dose and high-dose crocetin group. Animals were anesthetized with urethane (1.2 g/kg), then followed by the perfusion of aconitine (10 μg/mL) through caudal vein in rats, or of ouabain (9 μg/mL) through external jugular vain in guinea pigs in a constant velocity of 0.1 mL/min, and the emergence time of ventricular fibrillation, ventricular extrasystole, ventricular tachycanlia and cardiac arrest were then detected and recorded. The recorded time was then translated to the cumulated amount of aconitine and ouabain. Experimental arrhythmia was induced by rapid injection of 4% CaCl2 (140 mg/kg), and the emergence time, persistence time, incidence and death of arrhythmia after the administration were observed.

将实验动物随机分为生理盐水组，阳性药物对照组，藏红花酸高、中、低剂量组，SD大鼠采用1.2 g/kg乌拉坦麻醉后，从尾静脉匀速(0.1 ml/min)灌注10μg/ml乌头碱溶液，豚鼠麻醉后从颈静脉匀速(0.1 ml/min)灌注9μg/ml哇巴因溶液，观察出现室性期前收缩、室性心动过速、室颤和心脏停搏的时间，然后换算成乌头碱和哇巴因的累积量；快速推注4%氯化钙(140 mg/kg)诱导大鼠心律失常，观察给药后心律失常出现时间、持续时间、心律失常发生数及死亡数。

Form deprivation by monocular eyeshade was introduced between 2 and 3wk of age in all animals.

目的：研究豚鼠形觉剥夺性近视眼后极部巩膜胶原和蛋白多糖水平的变化，探讨其在哺乳类动物近视眼发生机制中的作用。

This fusion protein was also able to bind to rat or guinea pig fibrin, but not to pig fibrin.

它能与大鼠和豚鼠的纤维蛋白结合，而与猪纤维蛋白反应不明显。

Methods Established the Wistar rat models of EAE by footpad injection of guinea pig spinal cord homogenates and CFA. Animals were executed 6 days after disease onset, and optic nerves, brains and spinal cords were removed for light and electron microscope pathological analysis.

足垫皮下注射豚鼠脊髓匀浆和完全弗氏佐剂混合物制作Wistar大鼠EAE模型，于发病后第6 d将大鼠处死，取视神经、脑和脊髓，行HE和LFB染色，光镜和电镜下观察其病理改变。

Methods On the basis of bilirubin-induced encephalopathy model in guinea-pig, 10 μg/g of GAPA was injected intraperitoneal.

在制作胆红素脑病动物模型基础上予GAPA干预，观察对照组、模型组、模型干预组新生豚鼠（每组10只）干预后4、8 h脑组织超微结构、脑组织ATP含量与含水量。

Methods］Trichophyton mentagrophytes were scrubbed tightly on the back skin of guinea pigs,and the experimental animal models were set up .The ginger oleoresin gel were used in infective part,and alteration of skin lesions and pathologial changes were observed.

方法］ 采用砂纸造模法将须癣毛癣菌接种在豚鼠上，建立动物模型，观察药物对动物皮损的改变及病理改变。

If you have never clipped a guinea pig's toenails before, you may want to have your vet, or an experienced cavy groomer, show you how it's done.

如果你以前从来没有给豚鼠修剪过指甲，你可能想要找一个兽医，或一位经验丰富的猪猪美容师，告诉你如何去修剪它。

In the end, for guinea pig lovers like myself, it's all worth it!

在年底前，为豚鼠爱好者像我一样，它的一切都是值得的！

Do I have the time to care for and give affection to my guinea pig every day?

我有时间去照顾和给予我的感情豚鼠每天？

So smart cute little guinea pig, I can not like it?

这么聪明可爱的小豚鼠，我能不喜欢它吗？

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
