On the Influence of Low-Frequency Magnetic Field Disturbances on Basic High Resolution NMR Experiments

CDPcholine (citicoline, CDPCho) shows beneficial effects in various Central Nervous System (CNS) injury models and neurodegenerative diseases. Previous studies demonstrate conflictingMagnetic Resonance Spectroscopy (MRS) reports regarding the impact of different choline-containing compounds and its doses on brain metabolites. This preliminary study was designed to evaluate concentration changes of brain MR-visible metabolites following intravenous CDPCholine. Twelve healthy rats treated with CDPCholine in three subsequent doses of 1gram/kg eachwere examined using 1Hand 31P MRS in vivo. Following intravenous CDPCholine administration there was a statistically significant increase of the Cho/Cr ratio after first CDPCholine injection. The evidence of CDPcholine influence on brain metabolites has been shown.
