THE INHIBITORY EFFECT OF ACTINIDIA CHINENSIS PLANCH ON THE ENDOGENOUS FORMATION OF N-NITROSO COMPOUNDS IN SUBJECTS FROM A HIGH- RISK AREA FOR GASTRIC CANCER / 营养学报

The inhibitory effect of Actinidia chinensis Planch(ACP) juice on the endogenous formation of N-nitroso compounds (NOC) in the subjects from a high-risk area for gastric cancer were observed. Total concentration of volatile N-nitrosamines(VNA)in fasting gastric juice and 24-h urinary excretion of N-nitrosoproline (NPRO) were used as indices of endogenous exposure. After iagestion of 30 ml ACP juice the average total VNA concentration was significantly decreased from 2.08?1.06?g/L to 0.42?0.43?g/L (p
