It is not any fresh topic that the view point animal clones today. In the face of the rapid development of this field, the scientist says, people develop and clone animals (including cloning to transgenic animal) Original intention might for agriculture,however, might " the futures long-range " to clone animal when researching and developing by medicining with it . For example, draw protein and can be used for making medicines in the milk of cow and milch goat from cloning, it is expected to lower costs greatly that this kind uses pharmacy way which clones the animal. But have a lot of expert say, query to this they fear, escape from whom mankind control, clone animals and can pollute the species too, call upon the government to strengthen and supervise to it. Transgenic the intersection of animal and the intersection of pharmacy and the intersection of lab scale and the intersection of ox and organize the network report according to American physicist, it is numerous to use the example of cloning animal's pharmacy, for example, can draw protein and antibiotic in milk and blood of the milch goat or cow from cloning; Cloning chickens can give birth to the egg used for pharmacy; It is can be used for fostering human organ,etc. cloning pigs. The scientist says, through clone technology, producing the perfect replica of these animals can accelerate the pharmacy course and reduce the cost of pharmacy. For example, the biotech company Infigen Company located in Wisconsin state of U.S.A. uses cores to transfer technology, cultivating one carries on the piglet of genetic transformation, this kind of pig can be used for studying different kind of gene transplant (or different kind of transplantation, it is that cell, tissue or organ which use the animal treat the human incurable disease) . This company produces a group of cows transforming through the gene too, the company hopes to extract protein from milk and blood of these cows to treat hemophilia. However, this company is because of lacking the fund, had already been forced to close the door in 2004. Former president Michael and Bishop of this company explains: " at that time, we were trying new research, American Food and Drug Administration (FDA) Authentication course and getting getting more complete more so as now,take by wait-and-see attitude investors, make our development have difficulty in taking a step. " It is not unique, in 2006, the scientist of Masschusetts GTC biological drugmaker utilized milk collected in the ewe transforming from the gene to develop the medicine against blood coagulation for the first time - -ATryn. This medicine is the first kind of protein medicine to make through goat's milk in the world, the method is to transform the gene of the goat, makes their milk contain abundant resisting the blood coagulation albumen. The intersection of technology research and development and Vice President of GTC raise, end grams of Land claim, 150 medicines which milch goats produces are enough to meet hundreds and thousands of people's demands. Expert of FDA think, resist the medicine medical treatment of blood coagulation to have notable effect while being made of sheep's milk while being such, and very safe. In February of 2009, FDA will sanction being gone on the market by the medicine ATryn that the transgenic animal produces for the first time. This medicine has already been sanctioned selling in Europe too. To list medicine this can promote scientist develop, come on pharmacy through genetic living beings of transformation while being other, the current situation of pharmacy needs to come through the chemical material at present to change. The scientist is expected optimistically, over the next several years, it is expected to develop adopting the medicine made of the same method, benefit and suffer from the patient with hemophilia and other diseases. Ke Land Ai says, certainly, it is possible not to use clone technology at the same time, each road leads to Rome, only, the result of clone technology is more secure, and pharmacy is with low costs, high in efficiency. 2009, U.S.A. " the the New York Times " enumerate several in not researching and developing through transgenic the intersection of animal and medicine that technology produce too in report, for example, drugmaker, Pharming of Dutch, utilize transgenic recombination human C1 that milk produces of rabbit inhibit the protein medicine Rhucin ' Used for treating a certain hereditary protein defective disease) ,Has already applied to European medicines administration bureau for the listing licence in 2009, the final examination is expected to get permission to pass in the third quarter of 2010; And another company is developing by the transgenic goat expressing, medicine used for treating neural gas poisoning. The animal species can't ignore a lot of people and feel very pleased to pollute the question at this way of cloning animal's pharmacy. They think, the means of production of this kind of medicine can supply some important or rare medicines for the mankind steadily, moreover the intersection of mode of production and environmental protection, economy further its, does not need to break a huge sum of money and setting up the huge factory, can also reduce questions such as various environmental pollution,etc.. Also a lot of people leave a question open in cloning animal's heart sinuses, keep someone at a respectful distance. They say if some transgenosis clone animal, escape human control, mate with the natural animal, may initiate a series of question, for example pollute this species,etc.. Lawyer George and Jim of non-governmental organization Center for Food Safety has auspicious cloth to show: "We are from the experience that is learnt in transgenic crops, the nature has its unique reproduction ways, will change or will bring a series of question to destroy this way artificially. " He also says: "What I worry about is, once we produce these transgenic animals, we could take the corresponding measure, does and the human control that do not allow its escaping influence environment and public health through the food chain? " Zoological professor mark Cook of Wisconsin university Maddison branch school says: "As the scientist, we can produce safe cloning animals. However, the main problem is strengthening to the management cloning animal's pharmacy now. Time that may have taken from 10 years to 15 of wanting to obtain approval of FDA of a new medicine, and costs billions of dollars, this lets a lot of biological drugmakers can't bear the heavy load. " The heredity of non-governmental organization and fragrant gram of Sri Lankan of Peter of the social research center say, transgenic technology will initiate mankind's cruel question of treating animal too, this organization encourages people to use transgenic technology responsibly. Last year, a government owned corporation in New Zealand produced 4 transgenic calves, this company plans to use these calves to make and treat infertile and sterile hormone, at the very beginning, everything goes on very smoothly, the enormous ovary has appeared to there are 3 transgenic calf's development, however, 6 months later, among them both ends die unexpectedly. Fragrant gram of Sri Lankan still says: "Opinions vary for right such failed responses of people. But a lot of scientist have a detached attitude towards this, they think what major issue is the death of animal, but the cost that must be paid in the human learning process. We should look out this kind react, maintain vigilance to the intersection of scientist and such indifferent attitude.
