The day before yesterday, Cui Yichen and Li Qianfeng, students of the Technical College of Yangzhou University who had just won the 9th National University Student Challenge Cup award from Shanghai, gave their award-winning fruit, more than 3,000 rice seeds, to the school. In a few days, they will be sent to the school's expansion base in Hainan for experimentation. The experts reminded that these seeds are unusual, and they are very likely to crack down on the global problem of bird flu prevention and control of birds such as migratory birds, thus providing new ideas for the development of animal vaccines in the scientific community. Bird flu is becoming a public safety crisis in today's world. One of the effective methods for prevention and control at present is the use of vaccines to make poultry immune to injections. However, this method is incapable of migrating migratory birds and wild birds that migrate between regions. . The results of the “Construction and identification of avian influenza virus hemagglutinin gene transgenic rice†put forward by two students, Cui Yichen and Li Qianfeng of Yangzhou University, have provided a new idea for vaccine development to solve this problem: using transgenic technology to use rice as a vaccine vector. After migratory birds and wild birds are eaten, they can produce antibodies against bird flu viruses in the body, which is equivalent to giving them "injection" vaccines. Under the guidance of Professor Jiao Xin'an and Jin Lin, they used the leading national platform for animal immunology and plant genetics research to move this idea into the laboratory. In two years, Yangdahe College provided an innovation fund. After thousands of trials, he finally succeeded in detecting the hemagglutinin that can be expressed in cultivated rice, which is a welcome step. It is reported that in March next year, they will harvest the first batch of expanded rice seeds in Hainan; after testing and screening, it is planned to isolate rice seeds with stable gene expression through experiments and eventually complete animal experiments and biosafety verification. Apply as soon as possible.
Health foods contain a certain amount of functional health ingredients, which can regulate the functions of the human body, have specific effects, and are suitable for specific groups of people. General food does not have specific functions, and there is no specific range of people to eat. Health food cannot be directly used to treat diseases. It is a human body mechanism regulator and nutritional supplement.
