<i>In vivo</i>³¹P NMR studies of avian dystrophic muscles

Abstract

In vivo 31P NMR studies of normal and dystrophic pectoralis muscles of chicks were carried out in the age group of 2 to 8 weeks. It was observed that the ratios [PCr]/[Pi] and [PCr]/[ATP] were essentially the same in both normal and dystrophic muscles. The cellular pH for normal muscles however, was found to be higher (7.24 +/- 0.08) compared to the dystrophic muscles (7.0 +/- 0.07).
