Abstract

X irradiation of everted sacs of rat jejunum maintained in vitro, at about 10º C, provokes an immediate inhibition of the capacity of active transport of galactose. For this very high doses (20 Kr) are required, and the inhibition is of about 45 %. With 1,580, 3,000 and 10,000 r, no effect has been seen.

The presence of cysteamine (0.02 M-0.1 M) in the medium during irradiation does not seem to exercise radioprotective action.
