本文报导中华猕猴桃对体内N-2硝基脯氨酸(NPRO)合成的阻断效果。研究对象为15只雄性Wistar大鼠和10名男性健康志愿者。用自身对照分期观察。大鼠实验表明,中华猕猴桃汁可阻断体内NPRO合成(阻断率59.6％),且效果优于同浓度维生素C溶液,志愿者食入150g含75mg维生素C的中华猕猴桃可完全阻断服300mgNaNO_3和500mg脯氨酸后体内的NPRO合成,而75mg维生素C仅部分阻断。
This article reports on the blocking effect of Actinidia chinensis on the synthesis of N-2-nitroproline (NPRO) in vivo. The subjects were 15 male Wistar rats and 10 male healthy volunteers. Staged observation with their own control. Experiments in rats showed that Kiwifruit juice could block the synthesis of NPRO in vivo (the blocking rate was 59.6%), and the effect was better than the same concentration of vitamin C solution. The volunteers fed 150g of Chinese kiwifruit with 75mg vitamin C could completely block 300mgNaNO_3 And NPRO synthesis in vivo after 500 mg proline, whereas 75 mg vitamin C is only partially blocked.
