Prevention and control of avian influenza: octagonal efficacy is not based on the successful development of domestic drugs

Introduction: as a sub subject of the national "Tenth Five Year Plan" for scientific and technological research It is an important component of "development and application of new antibacterials and antiviral veterinary drugs" In 2000, researchers from the key open laboratory of new veterinary drug engineering of Lanzhou Institute of animal husbandry and veterinary medicine, Chinese Academy of Agricultural Sciences started the extraction and drug test of new hypericin preparations At present, the virus cell experiment, in vitro experiment and poultry experiment of the new preparation of hypericin have been completed, and the recently completed clinical experiment of artificial infection of H5N1 subtype avian influenza in laboratory poultry has also made a significant breakthrough Liang Jianping said that hypericin can be extracted from Hypericum perforatum, a Chinese herbal medicine, and can also be synthesized artificially It has the characteristics of low toxicity and low cost It can be directly added to animal feed and drinking water to prevent the virus, and it can also be used for the treatment of avian influenza and human infection after the outbreak According to the migration of migratory birds, the next step of the laboratory is to carry out large-scale prevention and control experiments of wild birds infected with avian influenza, and at the same time, it is necessary to over test to human body as soon as possible to develop drugs for human body to prevent and control avian influenza On October 28, according to the independent, the Chinese medicine octagonal has been found to be the only effective way to fight against bird flu in the world On the same day, the Chinese medicine star anise sold by a pharmaceutical company in Yichang, Hubei Province, was welcomed Beijing, Nov 8 - Tamiflu, an anti bird flu drug widely imported from Europe, is a special ingredient made from anise, which is made from China As soon as the news came out, octagons immediately attracted the attention of the medical community and the public Many people bought octagons to keep them at home Is octagon really effective? The reporter interviewed Qi Wensheng, director of the emergency department of Guang'anmen Hospital, Chinese Academy of traditional Chinese medicine Director Qi said that octagonum, as a kind of herbal medicine, belongs to the nature of warm and hot I'm afraid it has no effect on the treatment of avian influenza Moreover, there is no clinical experiment so far, which can prove that octagonal is effective in preventing avian influenza, so people should not rush to buy octagonal blindly Anise is commonly known as the big material, and the southerner is also known as fennel According to the theory of traditional Chinese medicine, avian influenza belongs to "fever" If it spreads among people, it belongs to pestilence and so on Cold medicine should not be used in the treatment of avian influenza If we want to use traditional Chinese medicine to treat avian influenza, we should also choose the medicine of clearing away heat and detoxification, especially paying attention to detoxification Octagon is generally used as a matching drug, but it does not play a fundamental role It is understood that octagonal has the functions of aromatizing and moistening, promoting blood circulation and removing stasis In addition to being the spice for seasoning, it can also relieve the symptoms such as nasal congestion and headache The medicine can be used for allergic rhinitis and people with cold constitution Otorhinolaryngology may use more octagons, but it is rarely used in internal medicine Director Qi also pointed out that many hospitals do not reserve octagons, which can only be bought in grocery stores Wang Liansheng, a senior lecturer at Singapore College of traditional Chinese medicine, said in an interview with the media that because the mechanism of action of traditional Chinese medicine is not clear, shikimic acid, the extracted octagonal component, may have antiviral effect But it's just laboratory results, which can't be equated with human experiments We hope the public will be cautious A new preparation for the prevention and control of avian influenza developed by the Key Laboratory of new veterinary medicine engineering of the Ministry of agriculture has recently completed the clinical trial of artificial infection of H5N1 subtype avian influenza virus in live chickens in P3 Laboratory of South China Agricultural University The results showed that hypericin extracted from traditional Chinese medicine had a 100% cure rate for H5N1 avian influenza in vivo and a certain inhibition effect on H9N2 avian influenza virus Liang Jianping, a researcher of Lanzhou Institute of animal husbandry and veterinary medicine, Chinese Academy of Agricultural Sciences and director of the new Veterinary Medicine Engineering Key Open Laboratory of the Ministry of agriculture, said that the success of the new drug preparation is not only of great significance to the prevention and control of influenza in Chinese poultry, but also can be further extended to the prevention and control of wild birds At the same time, through experiments, a drug for the prevention and control of avian influenza in human body can be developed as soon as possible Things.
