Abstract
Quantitative ^31^P NMR was used to follow the time variation of the hypometabolic response to hypoxic partial ischemia in an animal model. The purpose of the study was to establish the value of this repeated spectroscopy operating by means of a surface coil. It aimed at determining whether a therapeutic intervention could influence the transient changes occurring during the insult or early recovery. A pharmacological substance was thus used during a reversible forebrain ischemia, induced by a combination of vascular occlusion and mild hypoxia in two groups of rats. As an available and convenient example, Lβcarnitine was chosen. Statistical analysis of the experimental results revealed a significant difference of the P~1~ and PCr levels between treated and untreated animals.

Studies were performed on 16 cats to evaluate the potential protective effects of Gallopamil on brain ischemia. Brain energy state was determined by 31P NMR and lactate concentration was determined by 1H NMR. Double-tuned surface coils (tuned to 35.8 and 88.4, respectively) were placed on the head a

31P and 3-fluoro-3-deoxy-D-glucose (3-FDG) 19F nuclear magnetic resonance (NMR) spectroscopic investigations were performed on aged rat brain in vivo. Phosphodiester (PDE) was found to be significantly higher (p less than 0.05) in aged brain (18 months, n = 10) than adult controls (6 months, n = 10)
