超活体的

The object of this study is to cancerous and normal cells intimacy of hematoporphyrin derivative for diagnosis and therapy cancer, fluorescence spectra of cancerous and normal cells are measured using a ultrashort pulses laser spectral technique and picosecond time-correlated single-photon counting system.

研究用于癌症诊断与治疗的光敏剂血卟啉(hematoporphyrin derivative， HPD)对人体癌细胞与正常细胞的亲和性，采用超短脉冲激光光谱技术和皮秒时间相关单光子计数系统，测量经血卟啉培养的活体癌细胞与正常细胞的荧光光谱，观测到癌细胞样品在创645nm处具有特有的光谱谱峰；测量不同浓度血卟啉荧光光谱，观测到随着血卟啉浓度的逐渐增大，在645nm处出现的光谱峰也随之显著增强。

The ultramicroscope, the UV microscope and the luminescence microscope exemplify the inventive genius of those years and reflect three goals of microscopy, which have remained topical to date: Making ever smaller dimensions accessible to observation; observing living objects without damaging them; and finding methods to contrast the substances in such objects.

超显微镜，紫外显微镜、冷光显微镜的发明向我们展示了那个年代的天才智慧。同时也反映了显微术不断追求的三个目标：观察到更小尺度的物体；避免观察对活体的损伤；提高观察对象的图像反差。

Both groups were detected diopter using retinoscopic refraction, determined eyeball axis using ophthalmology ultra-A, and investigated the dynamic expression of VIPmRNA on posterior eyeball at three stages by RT-PCR.

两组均采用检影验光检测屈光度：眼科A超测定活体眼轴长度；对两组3个时间段眼球后壁行RT-PCR检测VIPmRNA的动态表达。

AIM: To label bone marrowderived stem cells with superparamagnetic iron oxid and to explore the image characteristics and signal attenuation rules of in vivo the magnetic resonance imaging of the labeled cells in rabbit liver.

目的：探讨超顺磁性氧化铁标记骨髓干细胞的方法和标记细胞在肝脏内的磁共振活体成像特点和衰减规律。

Once delivered to the heart, injected cells are difficult to distinguish from target tissue by MR in vivo.To specifically imaging injected cells in MR, the recent investigation generally using superparamagnetic iron oxid to label MSCs, which should enable serial tracking and quantification of MSC transplantation noninvasively by MR.

由于MR成像无法区分移植细胞和靶组织细胞，为使移植细胞能在MR上特异性显示，目前广泛使用超顺磁性氧化铁(superparamagnetic iron oxid， SPIO)作为负性标记物标记移植细胞，进行MR体外和活体内的成像研究。

In vivo exposure for 4 days to zinc and cadmium separately by immersion inhibited O2 production of phagocytes from head kidney, as that observed in vitro.

活体实验部份，浸泡於含锌及镉海水中四天，会抑制石斑鱼头肾吞噬细胞产生超氧根离子的能力，这和体外试验的结果一致。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
