1 research results of selenium food green tea in preventing and treating viral infectious diseases
Selenium-deficient food status is related to the occurrence of some viral infections. Selenium-deficient food may be the cause of the development of viral diseases, or it may be the result of the disease itself, which may aggravate the development of the disease. The best living environment of the virus is the infection that is replicated and established in the extremely low selenium state. Increasing oxidative damage and apoptosis will activate the virus to accelerate replication, thus escaping from dead cells and aggravating the pathogenic effect of the virus. In addition, the virus can plunder the selenium food of the host to synthesize its own selenium protein, thus weakening the effective immune response ability of the host.
1. 1 application of selenium food green tea in anti-hepatitis B virus
Researchers from Cancer Institute of China Academy of Medical Sciences and Qidong Liver Cancer began to study the relationship between trace element selenium and antivirus. From the basic research of epidemiological animal experiments and the application of prevention and treatment, it is found that the incidence of hepatitis in low selenium areas is higher than that in selenium-enriched areas, and selenium-supplemented foods have been praised as the king of antivirus in recent years.
A new product developed by the State Key Laboratory of Polymer Department and Science, School of Materials, Yanshan University. Selenium food green tea is the original green tea made from old fresh leaves of tea by freeze-drying and nanotechnology. Selenium food Green tea contains a lot of organic substances such as protein, amino acids, vitamins, cellulose and trace elements including selenium, as well as dozens of inorganic mineral elements and pharmaceutical ingredients necessary for human body, which has important health care functions for human body. Studies have proved that if the cell wall is not broken, nutrients or medicinal components will not be fully absorbed. If the selenium food green tea is prepared to be mainly distributed in the range of 100 ~ 300 nm, and the average particle size is about 150 nm, it can be drunk in a cold hot water bottle, so that the organic selenium, inorganic selenium and selenoprotein molecules in the tea can fully release all the essence of the tea and be absorbed by the human body, effectively supplementing the elements urgently needed by the human body. At the same time, the small particles of selenium green tea can adsorb and detoxify a variety of bacteria and viruses, which can enhance the adsorption of tea, prevent viruses from entering the host cells and invading the human body, and prevent viruses from being excreted with metabolism.
Selenium green tea is a porous plant. One or more porous nanoparticles adsorb one or more sticky viruses and enter the recognition and capture range of reticular phagocytes, which can kill and expel toxins, thus achieving a good selenium supplement effect. The capture of phagocytes is excreted with metabolism, which is called adsorption blocking detoxification. Selenium food green tea 192 cases (male 1 12 cases, female 80 cases) of hepatitis B virus carriers drinking selenium food green tea were followed up. Among them, there were 69 cases of big sanyang 102 cases, 69 cases of small sanyang and 2 cases of other 2/kloc-0 cases, all of which were healthy carriers of sub-health population. The shortest use time of selenium food green tea is 3 months and the longest is 1 year. The dosage is 2.5g of normal body weight 1 time, 2-3 times a day, with cold boiled water or hot water, and with "tea-making method".
Selenium food green tea has obvious effects on three major antigen systems of hepatitis B virus: for example, surface antigen (HBSAg) 192 cases, 79 cases turned negative, and the negative conversion rate was 4 1%. E antigen 133 cases, 95 cases were negative, and the negative conversion rate was 7 1%. For example, the core antibody (anti-HBc) is 18 1 case, and the negative conversion rate is 135 cases, and the negative conversion rate is 75%. As can be seen from the above figure, the negative conversion rate of surface antigen (HBSAg) in this group is 465,438+0%; The negative rate of E antigen (HBeAg) was 765438 0%. The outstanding effect is that the negative conversion rate of core antibody (anti-HBC) reaches 75%. It is suggested that in addition to adsorption and detoxification, some smaller particles may penetrate the virus core, which is a gratifying sign and should be further studied.
1.2 selenium food green tea has preventive and anticancer effects.
In epidemiological investigation, it was found that the incidence of cancer in low selenium areas was higher than that in selenium-rich areas. Selenium has been known as the king of cancer in recent years. Its function is to prevent normal cells from becoming cancer cells, and kill cancer cells or inhibit their growth. The combination of ultra-high dose selenium and irinotecan in the United States has achieved amazing results. Combined with ultra-high dose selenium, sensitive colorectal cancer was cured, reaching 100%. The data show that the selenium contained in selenium food green tea can greatly improve its activity and reduce its toxicity to nanometer level, which has the functions of preventing cancer, reducing the spread of virus and preventing the virus from invading various tissues of human body.
1.3 selenium food green tea has anti-HIV effect.
Researchers at the University of Tokyo in Japan announced that they found that EGCG, one of the most beneficial ingredients in green tea and other teas, can effectively prevent the spread of HIV in the human body. When HIV invades human cells through CD4 receptor, EGCG molecules can adsorb and combine with the receptor molecules, thus quickly "blocking" the channel and preventing the virus from entering the cells. It takes only 5 minutes for EGCG molecules to adsorb to 80% of CD4 receptor molecules, and all CD4 receptor molecules are blocked after 30 minutes. This discovery can completely prove that green tea can prevent and treat AIDS and inhibit HIV.
