3.2. The Antioxidant Effects of Cordyceps militaris before and
after Swimming. Antioxidant enzymes including GSH-Px
and SOD play important roles in preventing oxidative injury
in animals [18, 19]. Overproduction of a large amount ROS
leads to oxidative stress and deleterious effects on tissue [20].
To investigate the effect of CM on oxidative system, the
content of MDA, activities of SOD and GSH-Px in serum,
liver, and muscle, and the level of ROS in liver and muscle
were determined. Two-week CM treatment enhanced serumGSH-Px activity in female andmalemouse (
