The rats' levels of high-density lipoprotein (HDL) fell dramatically as well.
Finally, we re-assessed the rats' levels of impulsivity by replicating the delay-discounting test.
We first measured the rats' levels of impulsivity by means of delay-discounting and indifference-point procedures.
In diabetic rats, levels of serum testosterone, testicular reduced glutathione (GSH) and alpha-tocopherol were significantly reduced and testicular lipid peroxidation level was increased (p < 0.001).
As cytokine storm in the lungs may lead to lung injury [28], to further evaluate pulmonary inflammation in the septic rats, levels of inflammatory-associated cytokines including TNF-α, IL-1β, and IL-6 were measured in the BALF samples.
In brain regions of control rats, levels of 5HT, DA, and their metabolites showed few sex differences (Table 1).
In aging male rats, levels of hypothalamic NE either decreased [ 6, 13- 16] or remained unchanged [ 9, 17, 18].
In the III group of rats, levels of IL-10 significantly increased between the II and III stages of the experiment.
In the selectively bred, alcohol-preferring and non-preferring lines of rats, levels of 5-HT in the FC, ACC and C/P were lower in alcohol-preferring rats (Zhou et al., 1994).
Also, in peripheral blood lymphocytes and in spleens from stressed rats, levels of an important DNA repair enzyme, O6-methylguanine-methyltransferase, are reduced as compared with those obtained from control rats [ 105].
