The scientists find the secret against cancer of the black tea
Chicago, August 29 (Reuter's medical news) There has been emergence that can prevent and cure cancer. Through studying recently, the scientists have already known its reason. The anticancer included in the black tea " The secret weapon " It may be that one kind is known as flavin - 3 ' - eat son's sour salt (TF-2) only of tea Compound,last anticancerses compounds more than phenols this compound. Dr. Kuang Yu Chen of Rutgers university says at this chemical association's annual meeting of U.S.A. held on Wednesday, TF-2 demonstrates a lot of interesting characteristics while opposing cancer of colon: Unless after contacting TF-2, whose name is normal for cell free of any,but cancer cell will " commit suicide "s large quantities of . In the experiment, Dr. Chen and other researchers will add from TF-2 that is drawn in the tea to normal cell and colon rectum cancer cell and train in the system respectively. Found finally, normal cells grew actively, but the cancer cell began to wither to die --Procedure cell death. Through further research, researchers find, the activity that TF-2 seems to inhibit Cox 2 genes, Cox 2 genes have already become focuses studied, because once this gene has been activated, can touch off inflammation and react, it is that normal cells are changed into an obligatory one stage of cancer cell and inflammation reacts. Chen says: "We have already known the relation between Cox 2 and cancer of colon very much at present. " New medicine Vioxx and Celebrex used for treating arthritis at present can also inhibit Cox 2. Though every drugmaker is making great efforts to look for and inhibit the complicated material of Cox 2, Chen thinks they may have neglected the black tea very as one of their sources. However, a lot of problems remain to solve. Scientist confirm, can get up, get prominent against cancer result black tea optimum to drink consumption yet so far. Chen Dr. emphasize they still at primary stage about discovery of TF-2, need to carry on further research in animal and the human body too. Researcher say many phenol can be seen in other food and beverage still, green tea and the intersection of grape and skin, but the anticancer result of much phenol is not very prominent in these two kinds of food. However, through to the decoration of much phenol chemical constitutions in the peel of the grape in the laboratory, researchers can obviously improve their toxicity to the cancer cell.
