豚鼠

Objective After Intense pulsed light irradiation cavia cobaya skin, to evaluate the histological change of skin with HE stains; to evaluate the collagen fiber change with nitroxanthic acid stains; to quantitative analysis of hydroxyproline content. Confirm mechanism of action for Intense pulsed light on sun-damaged human skin.

目的 用强脉冲光照射豚鼠背部皮肤后，通过HE染色观察皮肤组织学的改变；用苦味酸染色观察皮肤胶原纤维的改变；定量分析豚鼠皮肤羟脯氨酸的含量，观察皮肤胶原蛋白的变化，进一步研究强脉冲光治疗皮肤光老化的作用机制。

Guinea pig Any of various small, short-eared domesticated rodents of the genus Cavia, having variously colored hair and no visible tail.

豚鼠，天竺鼠：一种体小、短耳的豚鼠属家禽啮齿类动物，毛杂色、尾短几不可见。

Methods Adopt the isolated guinea pig atrial sample,observe the influence of 7 chlor BTHP on some physiological properties of isolated left atrium and the beat rate of isolated right atrium.

利用豚鼠离体心房标本，观察 7 chlor BTHP对豚鼠离体左心房生理特性以及右心房心率的影响。

The effect of Sco on expression of RyR mRNA level of TSMC from asthmatic guinea pigs The presence of RyR mRNA was tested by RT-PCR using primer sets based on the 3'codding regions of the RyR genes.

说明哮喘组豚鼠TSMC上RyR2 mRNA表达明显降低，与对照组比较有显著差异（P＜0.01）；Sco组豚鼠TSMC上RyR2mRNA表达情况较哮喘组增强（P＜0.05）。

Methods:Animal model of skin chronic damage was done through daubing the skin of guinea pig with hair colour cosmetics available on the market. Body weight change of the guinea pig and ultrastructure change of the skin epidermis and dermal in electronmicroscope.

用市售染发剂涂抹豚鼠皮肤制作染发剂的皮肤慢性损伤动物模型，统计豚鼠的体重变化，以及用电子显微镜观察皮肤表皮和真皮的超微结构改变。

Methods Sulfanilamide was injected by abdominal cavity and by gavage as the photosensitizer in mice and guinea pig, Then the ear thickness of mice was measured and the erythematic reaction of guinea pig was observed at 4 h, 24 h, 48 h after induced by UVA plus UVB or only UVA.

以对氨基苯磺酰胺作为光敏剂，经腹腔注射与灌胃两种途径对小鼠和豚鼠进行给药，通过UVA加UVB光照诱导以及只用UVA光照激发后，于4h、24h、48h和72h分别测量小鼠耳厚度及观察豚鼠皮肤红斑反应。

Results Four weeks after surgery, animals in DO group showed an increased voiding frequency, higher voiding pressure and irregular nonvoiding contractions (n=12, P.05). We found increasing mutual connection and multilayer construction in suburothelium and intermuscular layers of DO but not DS and control bladders.

对照组、DS组和DO组豚鼠膀胱均观察到ckit染色阳性且呈典型长梭形有突起的ICC，主要分布于平滑肌肌束间和黏膜下层；在DO组豚鼠的膀胱中ckit染色阳性的ICC分支突起增加且互相连接呈网络状，而在对照组和DS组中ICC呈散在分布，细胞之间联系较松散。

The intravitreous injection of rhIGF-2 has no effect on the degree of myopia and axial length of the non-FD guinea pig, while it can induce significant increases in the degree of myopia and axial length in the FDM guinea pig and the effects are concentration dependent.

rhIGF-2玻璃体腔注射对豚鼠非遮盖眼的屈光度和眼轴长度无影响，但可使形觉剥夺眼近视屈光度增加，眼轴延长，其效应呈浓度依赖性。rhIGF-2可下调豚鼠眼视网膜－脉络膜内源性IGF-2的表达，效应呈浓度依赖性。

The hair colour cosmetics of 50％ and 100％ density can induce irreversible patho-damage in skin Malpighian cell and dermis fibroblast and inhibit the growth of guinea pig and so on.

50％、100％浓度的染发剂可导致豚鼠皮肤角质形成细胞和成纤维细胞发生不可逆病理改变，以及豚鼠的生长抑制等全身性影响。

There was a marked increase in phagocytic index when Ca2 + was added.

结果表明大鼠和豚鼠的正常吞噬能力无明显差异，Ca~(2+)可增加大鼠和豚鼠肺泡巨噬细胞的吞噬能力。

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。
