Abstract

^31^P nuclear magnetic resonance spectroscopy was used to study the skeletal muscle of 33 normal males and 32 females. Free intracellular magnesium levels and the ratios of the phosphorus metabolites were determined. Males had significantly lower free magnesium levels (499.8 ΞΌM Β± 26.3 ΞΌM vs. 530.7 ΞΌM Β± 36.0 ΞΌM, P = 0.001, d.f. = 63, analysis of variance). The free magnesium level (r~s~ = βˆ’0.5431, P = 0.001) and the phosphocreatine/inorganic phosphate ratio in males (r~s~ = βˆ’0.4102, P = 0.018), and the phosphocreatine/inorganic phosphate ratio in females (r~s~ = βˆ’0.4759, P = 0.009) fell with the increasing Minnesota Heart Health Program Questionnaire score.

## Abstract __In vivo__ ^19^F NMR measurements of trifluorinated neuroleptics in the rat brain were made using a 13 Γ— 18 mm surface coil at 4.7 T. The signal of fluphenazine was obtained within 8–15 min from brains of living rats treated chronically with drug doses of 5–30 mg/kg. Following the intr
