Each value represents the mean ± SD of observation made on samples from six animals from the same group. Statistical analysis was performed by the student t-test. Letter “a” and “b” indicate that the difference observed between the Groups I and II or between III, IV, V or are statistically significant at

^bP < 0.001 and

^aP < 0.05.
