摘　　要：应用放射免疫测定法分别测定了６周不同负荷训练后大鼠下丘脑、垂体和血浆β内啡肽（β＿ＥＰ）、强啡肽Ａ１—１３（ＤｙｎＡ１＿１３）、精氨酸加压素（ＡＶＰ）以及缩宫素（ＯＴ）含量的变化。结果发现，与对照组比较，大鼠６周过度负荷训练后，下丘脑和外周血中βＥＰ含量明显升高，ＤｙｎＡ１＿１３含量在下丘脑和垂体水平明显升高，ＯＴ和ＡＶＰ含量在下丘脑和外周血中均明显升高，但垂体水平ＡＶＰ含量明显低于对照组。６周一般负荷训练引起下丘脑、垂体和外周血中βＥＰ、ＤｙｎＡ１＿１３、ＡＶＰ和ＯＴ含量一定程度的变化，但与对照组比较无统计学意义。结果表明：６周过量负荷训练造成大鼠下丘脑、垂体和血浆内βＥＰ、ＤｙｎＡ１＿１３。The contents of β EP,Dyn A 1_13 ,AVP and OT in hypothalamus,pituitary and plasma were measured by radioimmunoassay(RIA) after the rats were swimming at various loads for 6 weeks.It was shown that the β EP contents in hypothalamus and plasma,the Dyn A 1_13 contents in hypothalamus and pituitary and OT and AVP contents in hypothalamus and plasma were significantly increased in the over_loaded rats compared with those in the control rats,whereas the AVP contents in pituitary were greatly decreased.A slight changes in β EP,Dyn A 1_13 ,AVP and OT contents in hypothalamus,pituitary and plasma were observed in the moderately loaded rats with no statistical significance.The results suggested that the six_week over_loaded swimming training strongly could affect the contents of β EP,Dyn A 1_13 ,OT and AVP in hypothalamus,pituitary and plasma in rats.
