Laser-excited fluorescence studies of mitochondrial function in saponin-skinned skeletal muscle fibers of patients with chronic progressive external ophthalmoplegia.
The functional behavior of mitochondria in skeletal muscle of patients with chronic progressive external ophthalmoplegia was studied by laser-excited fluorescence measurements of NAD(P)H and flavoproteins in saponin-skinned fibers. Variations in the mitochondrial content and the presence of partially respiratory chain-inhibited mitochondria can be detected using this novel method.
