Normal values of glycogen content in the dog skeletal muscle and liver.

Glycogen content was measured in the dog quadriceps femoris muscle and liver tissue under resting conditions after 24 h fasting period, using small tissue samples taken by a needle biopsy technique. The glycogen content in the quadriceps femoris ranged from 35.3 to 60.2 mM glucosyl units per kg of wet muscle with a mean of 50.0 +/- (SE) 1.2. The mean value of the liver glycogen content was 235.0 +/- 19.4 mM glucosyl units per kg of wet liver tissue with the average 121.1--316.1 mM glucosyl units per kg of wet tissue. It was calculated that approximately 127 mM glucosyl units of the glycogen is stored in the dog liver.
