Table 2. Enhancement Ratios^a Due to Combined Treatment With Thalidomide.

	With thalidomide (once)	With thalidomide (twice)
Surviving fraction = 0.03
Total cell population	1.0 ± 0.05b, c	1.25 ± 0.1c
Net micronucleus frequency = 0.6
Total cell population	1.0 ± 0.05d	1.2 ± 0.1d
Quiescent cells	1.05 ± 0.1	1.1 ± 0.1

^aThe ratio of the dose of radiation necessary to obtain each end-point without thalidomide to that needed to obtain each end-point with thalidomide. ^b Mean ± standard error (n = 6). ^{c, d}Significant differences between two values (P < 0.05).
