[Mutagenicity of tyramine extracted from salted dried fish in high-risk area of gastric cancer in Zhuanghe county].
Content of tyramine was determined in salted and dried small fish collected from high-risk area of gastric cancer in Zhuanghe County, Liaoning Province with high pressure liquid chromatography, and its mutagenicity after nitrosification was assayed. Results showed content of tyramine in the fish correlated significantly with its mutagenicity (r = 0.993, and P < 0.01). And, tyramine extracted from the fish was verified by thin layer chromatography.
