Abstract:
Objective To investigate the histochemical characteristics of muscle fiber in patients with Becker type muscular dystrophy (BMD) and its clinical significance.Methods Muscular biopsies were performed in 3 patients with BMD. The specimens were stained by HE and nicotinamide-adenine dinucleotid-tetrazole reducase (NADH-TR) methods and observed under light microscope. Normal muscles from healthy people were saved as controls.Results The slice from BMD patients showed varied sizes of muscular fibers, remarkable hypertrophy fibers, splitting fibers, targetoid fibers, lobulated fibers, whorled fibers and ring fibers. Targetoid fibers were also found using NADH-TR staining.Conclusions The degree of fiber necrosis in BMD is mild. Degeneration and proliferation are the main pathological changes, which predict mild clinical symptoms, long course of disease and favourable prognosis.
