(A) Effect of DHA (125, 250 mg/kg/day) and CP (10 mg/kg, single dose) on reduced glutathione (GSH) level in rat kidney homogenates. DHA was given throughout day1-day7 (or day10) of the experiment; depending on animal survival. CP was given on day4. Animals were sacrificed, kidneys removed and homogenates prepared. Data represent means +/- SEM of individual GSH levels in different groups, expressed as a percentage of the control group. Symbols indicate significance against; *CP-treated group; and °control group. (B): Correlation between GSH and creatinine levels in rat kidney homogenates treated with CP (10 mg/kg, single dose) and/or DHA (125, 250 mg/kg/day). r denotes the correlation coefficient obtained for the linear regression line.
