摘要
本文观察了绿茶水提取物对胃癌高发区人群体内N-亚硝基辅氨酸合成的影响。结果显示4.65g绿茶提取物(含维生素C75mg)可完全阻断高危人群体内过高的N-亚硝基脯氨酸合成(P<0.01),其效果强于同量维生素C(P<0.01)。受试者不同程度的胃粘膜病变对上述阻断作用无明显影响(P>0.05)。
Effect of green tea extract on endogenous formation of N-nitrosoproline (NPRO) in subjects froma high-risk area for stomach cancer was examined. The result showed that 4.65 g green tea extract(containing vitamin C 75 mg) completely inhibited elevated endogenous formation of NPRO in thesubjects (P<0.01) and the effect was better than that of the same dose of vitamin C (P<0.01). Thementioned inhibitory effect was not modified by severity of gastric mucosa lesions of the subjects (P>0.05).
