Effect of chronic administration of verapamil in Duchenne muscular dystrophy
1. 1. In DMD patients the effect of chronic treatment with verapamil was investigated in the p-nitrophenylphosphatase from erythrocytes, the CK and LDH in serum and the functional activity of the muscle. 2. 2. A different behaviour in the p-nitrophenylphosphatase from untreated compared to treated D...
