In skeletal muscles from rats treated with germanium for 23 weeks, there were numerous ragged-red fibers and cytochrome-c oxidase (COX)-deficient fibers. Biochemically, germanium reduced the enzyme activities in the mitochondrial respiratory chain. Rotenone-sensitive NADH-cytochrome-c reductase as well as COX activities were markedly reduced, while succinate-cytochrome-c reductase was less severely, but significantly, affected. The histopathological findings in these muscles were similar to those seen in patients with mitochondrial encephalomyopathy, suggesting that germanium-induced myopathy may be a useful experimental model. Coenzyme Q10 administration appeared to be ineffective in preventing this experimental myopathy.

The ability of the synthesized compounds of germanium with bioligands to affect the biosynthesis and activity of alpha-amylase and alpha-L-rhamnosidase has been studied. It was established the most complexes tested induced biosyntheis of alpha-amylase of Bacillus subtilis 147 (119-252%) with the exception of Pam (Pyracetam) and II (Ge-nicotinic-citric acid). At the same time the biosynthesis of alpha-amylase of Bacillus licheniformis 234 and alpha-L-rhamnosidase of Penicillium commune was inhibited by a number of synthesized compounds. The complexes IV (Ge-malonic acid) and VIII (Ge-nicotinamide-malonic acid) did not exert any effect on the biosynthesis of alpha-amylase however complex IV stimulated alpha-L-rhamnosidase biosynthesis on the 3rd day of producer cultivation. The study of influence of the studied germanium compounds on the activity of alpha-amylase and alpha-L-rhamnosidase gives every reason to suppose that they are the inhibitors of the above-mentioned enzymes.
