mRNA level of BDNF, NT-3, IL-6 and GDNF in the sciatic nerves in different groups at 28 day

Group	BDNF	NT-3	IL-6	GDNF
A	0.03 ±0.01	0.15 ±0.03	0.07 ±0.02	0.12 ±0.05
B	0.26 ±0.05*	0.12 ±0.02	0.05 ±0.01	0.09 ±0.01
C	0.29 ±0.03*	0.14 ±0.05	0.04 ±0.03	0.08 ±0.04
D	0.43 ±0.12* #	0.11 ±0.03	0.02 ±0.02	0.06 ±0.03

The mRNA level was expressed as x ± SD with mRNA level of β-actin set as 1. Group A – 0.9% saline treatment, group B – dexamethasone (1 mg/kg) treatment, group C – vitamin B₁₂ (2 mg/kg) treatment, group D – dexamethasone (1 mg/kg) and vitamin B₁₂ (2 mg/kg) treatment.
