Rubidium transport in irradiated vitamin-E-deficient bone marrow cells.

Abstract

We showed previously that the Rb+ transport rate in bone marrow cells (BMC) of vitamin-E-deficient mice is significantly lower than that in BMC of euvitaminotic mice. It is now evident that 4 h after whole-body, low-dose (0.01-1.0 Gy) gamma-irradiation of avitaminotic mice, there is an increase in the rate of Rb+ transport. This increase is quite pronounced, exceeding at all dose levels the rate of Rb+ transport in euvitaminotic mice exposed to the same radiation dose.
