Figure 8: The plasma glutathione (mg/dL) concentration measured in the arthritic and nonarthritic groups. When compared with the normal control group, a significant decrease in the level of glutathione (* ) was observed in the arthritic control animals. The NHAG treatment demonstrated a significant rise in the GSH level in comparison to the control arthritic group ( ). The treatment of indomethacin (5 mg/kg) did not exhibit any significant effect on the measured parameter.
