Electrical and freeze-fracture analysis of the effects of ionic cadmium on cell membranes of human proximal tubule cells.

abstract：:Recent investigations have demonstrated the ability of leukocytes to metabolize promutagens or procarcinogens into their genotoxic forms. As a possible explanation for the association between inflammation and cancer, we and others have hypothesized that local accumulations of leukocytes could take up nearby promutagen...
