| Abstract;For palliative therapy of Duchenne muscular dystrophy(DMD), corticosteroids have been tried since 1970. According to recent reports, corticosteroids maintained muscular strength to some extent and prolonged period of ambulation. However, their mechanism of action is mostly unclear. In the present study, mdx mice were injected with 0.6mg prednisolone 3 times a week for 30 weeks. Serum creatine kinase(CK) values remained 23% of controls. In muscle pathology of the quadriceps muscle, fibers with peripheral nuclei were increased, suggesting reduction of muscle necrosis. In pathological examination of liver, pyknotic cytoplasmic masses and formation of vacuoles were observed. Present study showed that prednisolone might attenuate muscle fiber necrosis at least for 30 weeks. Prednisolone may reduce secondary tissue reactions, which develop more serious muscle damage.
