Figure 6

The TRP, KYN, and KYN/KYN ratio levels in the hippocampus and cerebral cortex by surgical types and LPS administrations (n = 6). (A) TRP levels in the hippocampus, (B) TRP levels in the cerebral cortex, (C) KYN levels in the hippocampus, (D) KYN levels in the cerebral cortex, (E) KYN/TRP ratio in the hippocampus, (F) KYN/TRP ratio in the cerebral cortex. * indicates p < 0.05 versus BCCAL + saline and # indicates p < 0.05 versus BCCAL + LPS. Values are expressed in mean ± standard error of the mean (SEM). Abbreviations: TRP: tryptophan; KYN: kynurenine; HP: hippocampus; CC: cerebral cortex; BCCAL: bilateral common carotid artery ligation; LPS: lipopolysaccharide.
