Concentration of Metallothionein in Mice Livers after a Small Dose of Irradiation.

Metallothionein (MT), a low-molecular-weight protein, is induced in cultured cells and various animals by a variety of exogenous substances, including metals, organic solvents, and various agents, as well as by many kinds of physical stress such as UV or X irradiation, and injuries1_3). MT is considered to be closely related to radioresistance in mice and rats irradiated with large doses of ionizi...
