Group	SOD (Units/mg protein)	Catalase (µM H2O2/min/gm protein)	GST (µM/min/gm protein	GPX (µM/min/gm protein
Control	9.639±1.42	298.85±74.71	13.95±1.19	532.37±34.8
BLM	9.792±3.46	1185.04±27.76*	33.29±1.67*	719.07±29.18*
AA	11.53±3.45	274.84±52.95	14.38±3.45	732.91±89.15

IMR-32 cells were treated with AA 30 µg/ml and bleomycin 60 µg/ml and incubated for 24 hrs. At the end of treatment period, supernatant was collected and cells were lysed. All values are expressed as mean ± standard error (n = 3). *p<0.05 when compared to control. **P<0.01 when compared to Bleomycin. BLM = Bleomycin, AA = Arachidonic Acid, SOD = Superoxide dismutase, GST = Glutathione-S-transferase, GPX = Glutathione peroxidase.
