The activities of NADPH-dependent oxidative demethylation of aminopyrine and other methyl compounds in the liver microsomes from dystrophic mice were found to be about 30% higher than those of the normal mice. Consumption of reduced pyridine nucleotides during the demethylation reactions was also significantly larger in the dystrophic mouse system than in the normal mouse system. The synergistic effect of further addition of NADH on the oxidative demethylation in the reaction system with NADPH, however, was not significant in either the normal or the dystrophic mouse system. The activities of NADPH-cytochrome c reductase and lipid peroxidation were also higher by about 30% in the dystrophic mouse than in the normal mouse, but the contents of cytochrome P-450 and phospholipids in the liver microsomes from normal and dystrophic mice were not appreciably different. The results suggest the possibility that the progressive muscular dystrophy may involve abnormal features in not only muscle but also liver and other tissues.

It has been reported that amyotrophic lateral sclerosis-Parkinsonism-dementia in Guam might be related to the eating of Cycas seeds, which contain cyanide. Based on this assumption, we determined the urinary thiocyanate excretion level in patients with ALS and compared this with that of other neurological diseases. The assay method was designed to use column chromatography with Amberlite IRA 402. The thiocyanate level was determined using pyridine-barbiturate method. The 24-h thiocyanate level was higher in the ALS patients of the middle stages than in the normal control group (Wilcoxon's test, P less than 0.02). There were no significant differences between the ALS patient groups of the early and terminal stages, Kugelberg-Welander disease group, Duchenne type muscular dystrophy group and control group. From these results, we concluded that ALS patients were contaminated with cyanide or thiocyanate and that, along with rapid muscular atrophy, the thiocyanate excretion levels were high.
