Figure 4. Correlation between thiobarbituric acid reactive substances (TBARS) and cytochrome oxidase (CcOX) kinetic activity.

Figure 4

Linear regression analysis of level of TBARS with CcOX specific activity was performed. Pearson correlation coefficients and r-values were calculated. Values are expressed as means +/− standard deviation. (A) Correlation following 20 minute exposure. N = 3 animals per cohort. Pearson correlation coefficient is 0.06 and r-value is 0.24. P = 0.65. (B) Correlation following 40 minute exposure. N = 3 animals per cohort. Pearson correlation coefficient is 0.15 and r-value is 0.38. P = 0.45. (C) Correlation following 1-hour exposure. N = 6 animals per cohort. Pearson correlation coefficient is 0.94 and r-value is 0.97. †P < 0.002.
