摘要:By measuring concentrations of MT (metallothionein) and Zn in both malignant and non-malignant tissue of human liver, the following results were obtained. 1. MT concentration of non-malignant tissue in human liver was high and the data were 197, 538 and 552 μg/g. 2. The mean value of MT concentration in malignant tissue of human liver was 30.4 μg/g. 3. Between Zn concentration (x μg/g) and MT concentration (y μg/g) in the liver, a strong positive correlation (r=0.970) was observed. Its regression formula was y=-129+13.1x. The above results showed that MT concentration in human liver decreases by canceration.
