Objective To build Murine models with chronic fatigue syndrome（CFS） and investigate the effects of exercises on IL - 2 and NK Cell activities of Murine models with CFS. Methods Forty mice were randomly divided into four groups as Group I （comparative normal group, 10 mice）, Group Ⅱ （comparative CFS group, 10 mice）, Group Ⅲ （ exercise 1 group, 10 mice ）, GroupⅣ （ exercise 2 group, 10 mice ）. The Murine models with CFS were built by exhaustive swimming. After murine models were exercised by two kinds of intensity, their spleen indexe...
