綠茶可以減少關節炎、研究

Salah-uddin艾哈邁德,從密歇根大學健康係統,2007年在實驗生物學告訴與會者在華盛頓特區昨天茶提取物也可以抑製炎性產品類風濕性關節炎患者的結締組織。“我們的研究是一個非常有前途的步驟在尋找治療關節破壞經曆了類風濕性關節炎的人,”艾哈邁德說。結果增加了越來越多的科學消費與廣泛的健康益處,包括降低某些癌症的風險,減輕體重,心髒健康,預防老年癡呆症。綠茶含有30至40%的可以水萃取的茶多酚,而紅茶(綠茶,已經被發酵氧化)包含3至10%。這四個主要多酚中發現新鮮茶葉兒茶素(EGCG),兒茶素,表兒茶素沒食子酸鹽和表兒茶素。的研究中,並沒有看到全部NutraIngredients.com,專注於滑膜成纖維細胞-細胞形成襯裏的關節囊周圍的組織——從類風濕性關節炎患者。隨後這些成纖維細胞培養與EGCG在生長介質和孵化。促炎細胞因子interleukin-1β(IL-1beta)被添加到培養基中。IL-1beta據報道是免疫係統蛋白質發揮重要作用導致風濕性關節炎患者關節破壞。艾哈邁德告訴與會者,當與IL-1beta未經處理的細胞被刺激,一連串的事件發生,導致生產bone-destructive分子白細胞介素- 6 (il - 6)和cyclooxygenase-2 (cox - 2)。然而,當這些細胞被孵化與EGCG il - 6和cox - 2的生產並沒有觀察到。科學家們透露,工作正在進行實驗室測試關注EGCG在基因表達的抑製作用。 Animal studies will be used to test if EGCG can provide similar therapeutic or preventive effects against rheumatoid arthritis. Positive results could form a strong foundation for future testing of the green tea extract in humans with rheumatoid arthritis, said Ahmed. This study could be good news for the tea extract market. European demand for tea extracts is currently surging, having reached 500 metric tonnes by 2003. This has seen companies such as DSM, with its Teavigo boasting 95 per cent purity of EGCG, and Taiyo International, with its Sunphenon claiming more than 90 per cent purity, position themselves firmly in specific catechin markets. Approximately seven million people in the UK alone are reported to have long-term health problems associated with arthritis. Around 206 million working days were lost in the UK in 1999-2000, equal to £18bn (€26bn) of lost productivity. Source:2007年實驗生物學,華盛頓D。C, 2007年4月29日作者:S.-U。Ahmed Pakozdi和a·科赫
