为观察尾悬吊模拟失重对大鼠血清丙二醛（ＭＤＡ）含量的影响，２８只雄性Ｗｉｓｔａｒ大鼠随机分为４组，结果表明：悬吊１０ｄ的大鼠与对照组相比，血清ＭＤＡ含量没有显著变化，而悬吊２１ｄ的大鼠与对照组相比，血清ＭＤＡ含量则显著增加（Ｐ＜０．０５）。提示：模拟失重对大鼠血清ＭＤＡ含量有一定的影响。
To observe the effect of simulated weightlessness of tail suspension on serum malondialdehyde (MDA) in rats, 28 male Wistar rats were randomly divided into 4 groups. The results showed that compared with the control group, serum MDA There was no significant change in the content of MDA in the suspension of 21d rats compared with the control group (P <0.05). Tip: Simulated weightlessness has a certain effect on serum MDA content.
