Type of article: Article

Summary

THE FREEZE-INDUCED CONDUCTION BLOCK OF ACTION POTENTIALS OF RAT HEART IS APPARENTLY CAUSED BY A LOSS OF ELECTRICAL MEMBRANE POLARIZATION. BECAUSE THE MEMBRANE OF MANY FROZEN-THAWED CELLS WAS PRESERVED, IT IS SUGGESTED, THAT THE MAJORITY OF THE CELLS WERE NOT DEPOLARIZED BY AN EXCHANGE OF INTRA-AND EXTRA-CELLULAR IONS THROUGH MEMBRANE LESIONS, BUT THROUGH UNCLOSED NEXUS-CHANNELS BETWEEN INJURED AND NON-INJURED CELLS.
