| Modern Biological Technology is developing greatly, especially in the field of medical biological technology. Among all the fields of biological technology, medical biological technology accounts for 60%. Next to it is agriculture and other biological technology, which occupies 40%. For example, more than 600 companies in Western Europe that has over 800 biological technology companies belong to medical biological technology companies. Modern Biological Technology owns fantastic information. The speed of renewing its knowledge is very high. So, it is called the supportive industry in this century. It plays a very important role in several areas, such as improving the GNP, solving the crisis of population, food, energy and environment that human beings must be faced with. The application of the technology will accelerate the technological alteration of traditional industry and the formation of the newly-boomed industry. It can have a great influence on the human society. It possesses huge economic benefit and potential productivity. And it is the essential content of high-tech revolution in the 21st century.Modern Biological Technology is a fastly-developed subject. From its developing history, we can see that it has a strong experimental quality and a very brilliant subject characteristics. Firstly, its knowledge structure is novel and its developing speed is very high. Secondly, it has become an integrative subject which has numerous branches, covering different subjects. Thirdly, it is based on the experiences. All the features above make it combine with scientific experiments. In order to apply the theories to the reality, we use the modern biological technology to carry out the practice on biological medicine. We have adopted the method which is called " The study on the restraint operation on the carcinoma of bile duct cells that are the abnormal cells by wasabi extract" as an access to study the application of biological technology based on the combination of theory and practice and have got a good result. The main content of the study is:1. The produce of wasabi's efficient componential extract.2. The confirmation for the best medical concentration and the most restricted time using MTT experiment.3. The periodic analysis on the carcinoma of bile duct cells which are operated by wasabi extract with the method of PI staining method?4. The test on the carcinoma of bile duct cells' fadeout made by wasabi extract.5. The effect on the density of CD44v6 on the cancer cell membrane caused by wasabi extract.6. The morphology manifestation of cancer cells' fadeout made by wasabi extract.The actualization of this study here comes to a conclusion that wasabi extract has an obvious restraining effect on the carcinoma of bile duct cells. What's more, it studies on many different aspects. For example, the periodic cell change after functioning on the cancer cells; the fadeout of cells; the density of CD44v6 on the cancer cell membrane; the morphology of cell fadeout. It is involved in lots of knowledge and skills in the course of Modern Biological Technology and brings the fundamental knowledge to. the practice during which we can understand and master more of the basic lore. It also proves that in the course of combination of knowledge and practice, it can not only consolidate the major knowledge and basic technology, but also cultivate the abilities that the graduates must have.This thesis studies on the brand-new subject. It dissertates that when we study Modern Biological Technology, we should grasp the peculiarity of this subject and positively exert out subjective capability. The most important is to combine the knowledge in the books with the scientific practice and thus can make the graduates possess the integrative abilities. |
