英文摘要 |
The concentrations of Zn, Mn, Fe, Cu in tumor and non-tumor regions from human hepatocellular carcinoma (HCC) specimens were measured by ICP-AES. Resected liver tissues from eighteen patients with HCC were collected for this study. Lower zinc and manganese ion concentrations were demonstrated in tumor regions (Zn+2,P <0.05;Mn+2,P <0.0005). It might indicate lower activities of some glucose metabolic enzymes in HCC tumor tissues, such as lactate dehydrogenase, glucokinase and pyruvate dehydrogenase. No significant differences in the concentrations of iron (P=0.78) and copper (P=0.12) ions between tumor and non-tumor regions were found. |
