Eating more papaya keeps cancer away from+00 March 1 1 03 08:02 Nanfang Daily font size: t | tResearchers in the United States and Japan found in laboratory experiments that papaya has anti-cancer effect, and papaya leaf extract can kill cancer cells. The results of this study were published in the Journal of Ethnological Pharmacology. Researchers are studying the anti-cancer principle of papaya and the specific components that play an anti-cancer role. Deng Nan, director of the clinical trial office of the Shanz Cancer Center of the University of Florida in the United States, and researchers at the University of Tokyo in Japan found that the extract of dried leaves of papaya has anti-cancer effect, which is effective on a series of human tumor cells cultured in the laboratory, including cervical cancer, breast cancer, liver cancer, lung cancer and pancreatic cancer. The higher the concentration of the extract, the more obvious the anticancer effect. The researchers exposed 10 different types of cancer cell media to papaya leaf extract, and after 24 hours, it was found that the growth rate of cancer cells in all media slowed down. In order to prove the anti-cancer principle of papaya leaf extract, the researchers focused on a T-cell lymphoma cell line. It is found that one of the principles is that papaya leaf extract leads to cancer cell death. In similar experiments, the research team also found that papaya leaf extract can promote the production of Th 1 cytokine, which plays an important role in regulating the immune system. Researchers who have no toxic side effects believe that the results of this study increase the possibility of using papaya extract components to treat immune system-related diseases in the future, such as inflammation, autoimmune diseases and some cancers. Papaya also has a significant advantage in anti-cancer, that is, it has no toxic side effects. Papaya extract can act on cancer cells, but it has no adverse effect on normal cells, thus avoiding the harm caused by some cancer therapies to the human body. Agence France-Presse quoted Deng Nan as saying on the 9th that papaya has no toxic side effects, which is consistent with many Australian and Vietnamese studies. "According to what I have seen and heard in clinical trials, no one has shown any side effects because of this extract," Deng Nan said. "It seems that you can take this extract for a long time until it works." Animal experiment to be done Bharat Agarwal, MD, Anderson Cancer Center, University of Texas, said that although Dunnan's research paper did not confirm the specific anticancer components of papaya, "this is a good start". Agawal is convinced of the ability of papaya to help the human body recover. He eats a papaya every day. "We already know that papaya contains many interesting ingredients," agarwal said. "Among the ingredients that are beneficial to human health, the most important one is papain, which exists in fruits and leaves." He said that papaya extract has successfully reduced the number of cancer cells artificially cultured in the laboratory, and the next step should be applied to animal and human research. "I hope Dr. Deng can go further. I think we need someone as enthusiastic as him to push it, "agarwal said. Deng Nan is leading a research team to analyze the specific anti-cancer components in papaya extract. Huang Min Xinhua News Agency is a special feature of this newspaper.
