【朗報】緑茶のカテキンが前立腺がんの予防に効果ありとの研究結果【Good news】 Research result that green tea catechin is effective for

緑茶の健康効果は数多挙げられるが、この度前立腺がんを予防できるとの男性には嬉しい研究結果が発表された。A number of health benefits of green tea can be cited, but research results that were pleasant to men to announce that they can prevent prostate cancer this time were announced.

米Moffitt Cancer Center & Research InstituteのNagi B. Kumar医学博士らによる研究では、緑茶に含まれるカテキンには、非がん性の腫瘍ががん化するのを防ぐ働きがあり、前立腺がんを予防できることが明らかに。In a study by Nagi B. Kumar medical doctors of Moffitt Cancer Center & Research Institute of the United States of America, catechin contained in green tea has a function to prevent cancer-free cancer from cancerous cancer, prevent prevention of prostate cancer Clearly you can.

没食子酸エピガロカテキン（EGCG）Epigallocatechin gallate (EGCG)

同医学博士らはカテキンの中でも、最も抗がん効果の高い没食子酸エピガロカテキン（EGCG）を抽出。49人の被験者に1年間、毎日200ミリグラムの緑茶カプセルを2錠服用してもらった。The medical doctors and others extracted epigallocatechin gallate (EGCG) which has the highest anticancer effect among catechins. 49 subjects took 2 tablets of 200 mg of green tea capsule each day for 1 year.

前がん病変の変化に違いThe difference in pre-cancerous lesion changes

すべての被験者が高悪性度の前立腺上皮内腫瘍（HGPIN）または、前立腺に腺がんを疑う小病巣（ASAP）が認められていたが、カテキンを配合した緑茶カプセルを服用していたか否かで、前がん病変の重症度に違いが認められた。 緑茶カプセルを服用していたHGPINの被験者は、がんへと近付く次のステージであるASAPに進んでいたり、完全な前立腺がんと診断されたりする割合が少なかったという。また、前立腺がんの腫瘍マーカーとしても用いられる、前立腺特異抗原の値も低ようだ。

All subjects had high-grade prostatic intraepithelial neoplasia (HGPIN) or small lesions (ASAP) suspected of adenocarcinoma in the prostate, but whether or not they were taking green tea capsules containing catechin , There was a difference in the severity of pre-cancerous lesions. Subjects at HGPIN who were taking green tea capsules said that they were proceeding to the next stage of ASAP approaching cancer, or that they were diagnosed as complete prostate cancer. Also, the value of prostate specific antigen used as a tumor marker for prostate cancer seems to be low.

今回はカテキンの持つ前立腺がんの予防効果が証明されただけでなく、これまではマウス実験でのみ指摘されてきた、緑茶の抗がん作用が人間にも有効であることが併せて明らかになった。 尚同研究結果は、今週開催された米臨床腫瘍学会の席で発表されたものである。In addition to proving the prophylactic effect of prostate cancer possessed by catechin this time, it is clear that the anti-cancer action of green tea, which has been pointed out only in mouse experiments so far, is also effective for humans became. The results of the study were published at the American College of Oncology Society held this week.
