豚鼠

In the present study, the effects of chloride channels blockers,(Niflumic acid,NFA;IAA-94;DIDS) on EJP were explored in guinea pigs, using intracellular recording techniques on acute isolated spiral modiolar artery.

本实验运用细胞内微电极记录技术，在豚鼠耳蜗螺旋动脉(spiral modiolar artery， SMA)离体标本上，研究氯通道阻断剂(Niflumic acid， NFA； IAA-94； DIDS )对去甲肾上腺素引起SMA平滑肌细胞的反应和平滑肌细胞EJP的影响。

Methods: the spiral modiolar artery in guinea pig cochlea was exposed by microsurgery, then the fluorogold or horseradish peroxidase was given around the sma for retrograde tracing. the bilateral superior cervical ganglia and stellate ganglia were observed to find retrogradely labeled neurons. the neurotransmitters of these sympathetic fibers around sma were ascertained by using retrograde tracing combined with immunohistochemical double labeled technique.

在正常豚鼠单侧耳蜗螺旋蜗轴动脉局部滴加逆行追踪剂辣根过氧化物酶或荧光金，观察双侧交感颈上神经节、星状神经节内hrp或fg逆标神经元的分布；采用逆标与免疫组化相结合的双重标记方法观察追踪阳性神经元是否表达酪氨酸羟化酶、神经肽y、钙基因相关肽或p物质。

Results showed that the size and density of myenteric plexus in each intestinal segment were quite different.

实验豚鼠经常规灌流固定后，取不同肠段1cm的肠管做全部纵肌层撕片，然后进行免疫组织化学反应。

Some researchers have found that SP could affect other neurons in enteric nervous system . However, little is known about the mechanism of SP on the myenteric cholinergic neurons.

本研究采用全细胞膜片钳技术和免疫细胞化学技术探讨了SP对豚鼠回肠肌间丛胆碱能神经元电活动的影响，为揭示肽类递质对胆碱能神经元的调节机制提供依据。

Objective To investigate the effect of Artesunate on experimental immune myositis animal model.

目的 建立类似于人类多发性肌炎/皮肌炎的豚鼠模型，观察青蒿琥酯对此模型的影响。

The animals were then killed,color of colon was observed and score of degree of nigrities was evaluated.

结论用大黄可致豚鼠实验性结肠黑变病，黑变程度与大黄剂量及时间相关。

A dynamic generating toxic gas system and a nose-only exposure system were used for the pharmacokinetic study of inhaled environmental contaminants for benzene, toluene, xylene, ethylbenzene,chlorobenzene, styrene, isopropyl benzene, tetrachloroethylene, nonane and methylcyclohexane in male guinea pig.

用动态配气设备和鼻式吸入方式染毒，采用雄性豚鼠对环境中10种挥发性污染物(苯、甲苯、对二甲苯、乙基苯、氯代苯、苯乙烯、异丙苯、四氯乙烯、甲基环己烷和壬烷混合物)的吸入动力学进行了研究。

It is probably that there were not Ca〓 channel on the guinea pig sperm PM, because the Ca〓 channel blockers verapamil, nifedipine, diltiazem and D600 promoted acrosome reaction in synchronous and nonsynchronous cultural systems.

豚鼠精子质膜可能无Ca〓通道，因为verapamil、dilliazem和D600等对获能和未获能的精子的顶体反应均具有显著的促进作用。

In the third part, Ginaton and FK506 were used to improve the reperfusion of the xenograft model. When the rats were pretreated with Ginaton 30min before the transplantation, the PVBF of the xenografts at time 0, 15, 30, 45 and 60min after transplantation were 0.406±0.020, 0.357±0.025, 0.308±0.013, 0.249±0.019 and 0.205 ±0.014kHz respectively, significantly higher than those of the nontreatment rats.

为了改善豚鼠至大鼠肝移植后移植肝的微循环再灌注障碍，在接下来的第三部分中，分别进行了微循环改善剂金纳多、免疫抑制剂FK506和两者联合应用的作用研究。

It is suggested that Ginaton may improve the microcirculation of the xenografts and lighten the HAR. The PVBF after FK506 pretreatment were 0.466±0.049, 0.399±0.037, 0.358± 0.040, 0.317±0.039 and 0.258±0.033kHz, the survival time was 215. 9±16. 0min, significantly higher and longer than those of the nontreatment recipients.

发现移植前30分钟应用金纳多移植后0、15、30、45和60分钟多普勒超声测得的移植肝PVBF波幅分别为0.406±0.020、0.357±0.025、0.308±0.013、0.249±0.019和0.205±0.014kHz，与未用药组相比其降低的程度有明显降低，说明金纳多具有改善豚鼠至大鼠移植肝的微循环，具有减轻排斥反应的作用。

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。
