ON THE BETTERMENT OF FIXATION METHOD OF ACCUMULATED CADMIUM IN KIDNEY

Abstract

Five different cadmium fixation methods of kidney were investigated in view of the leakage of the metal into fixative solutions and into the other materials for electronmicroscopic preparation. On the other hand, they were examined whether the fine structure was preserved well or not for light-and electronmicroscopic radio-autography. The better method was choiced, to add tannic acid to a fixative contain-ing paraformaldehyde and glutaraldehyde buffered with phosphate.
