From: Comparative effect of transforaminal injection of Magnesium sulphate versus Ozone on oxidative stress biomarkers in lumbar disc related radicular pain

  Mg sulphate group (n=45)
Mean (SD)
Ozone group (n=45)
Mean (SD)
Control group (n=45)
Mean (SD)
SOD serum level Before intervention 12.4 (2.78) 12.12 (3.07) 12.75 (2.8)
After 2 weeks 13.04 (2.93) 15.16 (3.44) 12.32 (2.63)
P- value 0.005* <0.001* 0.059
P- value between groups 0.153
GSH serum level Before intervention 24.46 (6.76) 25.42 (6.62) 24.61 (6.55)
After 2 weeks 26.1 (8.08) 30.99 (7.62) 24.42 (6.33)

P- value between groups 0.031*
  1. GSH: Glutathione, SOD Superoxide dismutase
  2. *P-value ≤ 0.05 is considered significant
