Abstract:
:Serial ion-exchange and high-performance liquid chromatography separations were employed for the tissue extraction and purification of kynurenic acid (KYNA). Subsequently, the compound isolated from postmortem human brain tissue was unequivocally identified as KYNA by nuclear magnetic resonance and mass spectrometric analyses. Regional distribution analyses revealed the highest concentration of KYNA (1.58 +/- 0.43 pmol/mg tissue) in the caudate nucleus with lower levels in the thalamus, globus pallidus, hippocampus, parietal cortex and frontal cortex. Of the brain structures examined, the lowest concentration of KYNA (0.14 +/- 0.02 pmol/mg tissue) was found in the cerebellum.

BRAIN RESEARCH文献大全abstract::Intraocular injections of several different retrograde tracers were made in albino rats. Retrogradely filled neurons were observed in two locations: the medial pretectal area and the contralateral periaqueductal grey matter, indicating that the pretectum and the mesencephalon are sources of centrifugal innervation to ...
