The best quality of MRS is that the MRS is the only noninvasive and in vivo means in detecting the changes in metabolism state and special biochemical compounds in living animal and human body, and that make it possible for us to observe the physiological and biochemical characteristic of brain neoplasma ,and the development of neoplasma.

脑肿瘤是较为常见的肿瘤，其发病率占全身肿瘤的1.8％，其中以脑胶质瘤为最多，占43.7％，脑肿瘤的诊断及治疗一直是临床及基础研究的难点及热点，为了更好的了解胶质瘤的生物学特征，寻找有效的治疗方法，人们一直在寻求建立稳定安全的脑动物模型，大鼠C6胶质瘤具有与人脑胶质瘤相似的生物学特征，且模型较为稳定，被广泛用于肿瘤生物学及实验性治疗的研究中。

Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.

本研究结果显示，(1)单独应用TTE作为影像学引导进行冠状窦电极导管置放的成功率为93.8％～96.7％，并且应用TTE作为影像学引导放置专用冠状窦电极导管和普通电极导管的成功率和放置时间在统计学上无显著差异；(2)TTE作为影像学引导，除过度肥胖患者外，可完全替代X线引导进行冠状窦电极导管置放，包括鞘管和扩张管的放置、指引导丝在静脉而非动脉内的证实均可由TTE完成引导，且较X线C型臂有一定优越性；(3)TTE结合普通X线胃肠透视机作为影像学导引，可顺利完成心内电生理检查时导管的安全到位，而不需昂贵的X线C型臂，可将心内电生理检查扩大到广大的基层医院；(4)TTE较X线更易和更早期发现介入治疗的并发症如急性心包填塞等，对并发症的防治甚至挽救病人的生命至为重要；(5)动物实验研究表明，TEE可引导射频导管消融术时大头电极导管成功到位。

Searching for specific ligand to a certain recepter or enzyme in human body from secondary metabolities of plants, animals and microorganisms, Optimization of lead compound under certain theory or hypothesis, and synthesis methodology investigation of pharmaceutically active compound are all tasks of medicinal chemistry.

药物化学的研究领域十分宽广，既有从动物、植物、微生物的次生代谢产物中寻找与人体内特异性的受体、酶的激动剂或拮抗剂，又有在理论、假想指导下的先导化合物的优化，以及生理活性化合物的合成方法学研究。

Previous animal model studies have shown that benzyl isothocyanate and phenethyl isothocyanate inhibit carcinogenesis and tumorigenesis. However, the effects of BITC and PEITC on the formation of human osteosarcom are still not clear.

由过去研究发现，Benzyl isothocyanate与Phenethyl isothocyanate在动物模式下可以抑制化学致癌物引起癌化与肿瘤生成，但对於人类骨肉瘤的形成尚未有相关研究。

Even studies of phylogenetically disparate species, such as songbirds, can suggest to us some things about what we humans are doing and, conceivably, how we might be doing them.

甚至是对那些在系统发生上和我们人类在本质上根本不同的动物的研究，比如对鸣禽的研究，也能够向我们揭示出一些关于&人类在做什么&和&人类是怎么做的&这样的信息的。

ABSTRACT Purpose By adding additives in carbonated hydroxyapatite cement to increase its rheology to prepare injectable carbonated hydroxyapatite cement.(1) Test the physicochemistry characteristics of ICHA cement.(2) Evaluate the biocompatibility of ICHA cement.(3) Biomechanieal appreciation of ICHA cement used in distal radius fracture.(4) Study the mechanical stability, degradation and bone formation ability of ICHA cement used in goat lateral tibial plateau compression fracture.
