Cremaster series download1/4/2023 “Phosphate potential” indicating the efficiency of phosphorylating systems decreased suggesting that the denervated muscle has a greater utilization and a lower phosphorylating efficiency. A significant reduction in lactic dehydrogenase, creatine phosphokinase, phosphorylase, actomyosin and myosin ATPase and Na-azide sensitive ATPase activities were noted after denervation. Levels of ATP, creatine phosphate and pyruvate also decreased while ADP, creatine, Pi and lactate concentrations increased. Sarcoplasmic protein/unit wet wt remained unaltered, while collagenous proteins increased and myoglobin, myosin and actin content decreased. There was about 34.56 ± 1.26% atrophy in muscle fiber as measured by its cross-sectional area. On presentation/unit DNA, protein increased suggesting volume changes of the muscle fiber on denervation. Total fat, glycogen/g wet wt and total DNA/g wet wt increased, whereas the water content and the levels of total protein and RNA decreased. Transection of genitofemoral nerve resulted in a number of changes in the composition of the bonnet monkey cremaster muscle in a 58 day period.
