Abstract: |
A method for reducing calcium overload in cells to prevent the transition from reversible to irreversible injury. The cell surface is treated with an organic polycation selected from the group consisting of protamine, dodecyltrimethylammonium bromide, polymyxin B sulfate and polybrene which is capable of altering the cells surface charge sufficiently to eliminate or reduce the influx of calcium resulting from exposure to noxious stimuli. The method may be used both in vivo and in vitro. The method is effective in preventing calcium uptake in a variety of cell injury situations including metabolic inhibition and free radical attack.

What is claimed is:
1. A method for reducing the uptake of calcium by a mammalian cell wherein said cell includes a surface having a surface charge, said method comprising the step of treating said cell surface with a sufficient amount of a cationic agent to alter the surface charge of said cell to reduce the uptake of calcium by said cell wherein said cationic agent is selected from the group consisting of protamine, dodecyltrimethylammonium bromide, polymyxin B sulfate and polybrene.
