Abstract: | The effect of myofibrogranuloma (skeletal muscle degeneration) on serum calcium levels in spawning walleye ( Stizostedion vitreum ) was examined. Mean serum calcium levels for healthy male walleye (11.7 ± 1.5 mg/10 ml serum) was significantly lower ( P P < 0.1) in serum calcium were seen between healthy male and myofibrogranuloma-diseased male walleye (13.6 ± 2.1 mg/100 ml serum) and between healthy and myofibrogranuloma-diseased female walleye (20.2 ± 3.7 mg/100 ml serum). Elevations seen in mean serum calcium levels suggest the muscle degeneration and subsequent granuloma formation in later stages of myofibrogranuloma have a significant effect on serum calcium. |
