Neuronal counts in L5 DRG of wild-type and IL-6 −/− mice 14 d after sciatic nerve transection

	Contralateral	Ipsilateral	Ratio (I/C)
WT	3555  ± 201	2470  ± 134	70  ± 2
KO	3268  ± 261	1840  ± 157	57  ± 4*

Neurons with distinct nucleoli were counted by a blinded observer in every fifth section from contralateral and ipsilateral DRG removed 2 weeks after sciatic nerve transection (mean ± SEM;n = 9 mice in each group). Note that the mean of the ratios is not the same as the ratio of the means. *p < 0.05 by Student’s t test or Mann–Whitney rank sum test. Neuronal counts in the contralateral DRG tended to be lower in IL-6 −/− mice than wild-type mice, but this trend did not reach statistical significance. WT, Wild-type mice; KO, IL-6 −/− mice.
