The Correlations of Physiological Factors Such as Body Weight and Corticosterone Levels Together. (A) Plasmacorticosterone (nmol/L) measured in rats in response to behavioral tests immediately after the fear memory test. (B) corticosterone levels in the control short-term group, negatively correlated with body weight gain after seven days of the experiment. In the exposed short-term group, relative body weight was (C) negatively correlated with corticosterone levels. (D) Control long-term, and (E) exposed long-term groups positively correlated with corticosterone levels after one month. The data are expressed as the mean ± SD. One-way ANOVA using the Tukey test was used to compare all groups. r = Pearson’s correlation, P = significant value. ns indicated no significant,^*P < 0.05, ^***P < 0.001 and ^****P < 0.0001. Student’s t test was used to compare the short-term and its control group, and the long-term group and its control group.
