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).
摘要
对2至8周龄雏鸡的正常和营养不良胸肌进行了体内31P核磁共振研究。观察到正常肌肉和营养不良肌肉中[磷酸肌酸]/[无机磷]和[磷酸肌酸]/[三磷酸腺苷]的比值基本相同。然而，发现正常肌肉的细胞pH值（7.24±0.08）高于营养不良肌肉（7.0±0.07）。
