| 摘 要： | 为探讨铜缺乏对奶牛红细胞及组织细胞膜ATP活性的影响，在调查铜缺乏奶牛水土食物链微量元素状态的基础上，首次测度了病区6头发病犊奶牛（Ⅱ组）及该地区20头同年生临床健康奶牛（IH组，血清铜低于0.56mg/kg）红细胞膜Na^ -K^ -ATP酶、Ca^2 -ATP酶及Mg^2 -ATP酶的活性，对20头IH组奶牛进行为期80d的补铜试验（含铜40mg/kg干饲料），以20头健区同年生健康奶犊牛作为对照（HH组，全血铜大于０.85mg/L）。同时测试了剖杀后６头病牛及健康牛组织细胞膜ＡＴＰ酶的活性。结果表明：Ⅱ组奶牛红细胞膜ＡＴＰ酶活性显著低于ＨＨ组及ＩＨ组。补铜后４０d，ＩＨ组奶牛红细胞膜Na^ -K^ -ATP酶均显著升高，病牛肝、脾、肾、大脑、小脑、淋巴结等组织细胞膜Na^ -K^ -ATP酶、Ca^2 -ATP酶活性显著低于对照组。结论：铜缺乏较为严重地影响了奶牛红细胞及组织膜ＡＴＰ酶的活性，抑制了这些组织的正常生理功能。

| Abstract: | This study investigated the activities of Na+-K+-ATPase,Ca 2+ -ATPase and Mg 2+ -ATPase on the red cell membranes of 6 invalidcalves (ll Group) and 20 clinically healthy ones(IH Group,the serumcopper below 0.56 mg/L) at same age on condition that the status oftrace element on the soil-food chain were studied.The aim of this studywas to discuss the effect of copper deficiency on the activities of ATPase.20 IH Group calves were supplemented with 40 mg Cu/kg dry feedwhile 20 healthy calves in non-affected area were selected as control(HH Group,the content of whole blood copper is more then 0.85 mg/L).Theactivities of tissue membrane ATPase were also determined in 6 invalidcalves and healthy ones at same age.Results:The activities of ATPase ingroupll is significantlylower than that of group IH and HH.The activtiesof Na+-K+-ATPase and Ca 2+ -ATPase of red membrane of group IH were signifiantly improved after 40 days of copper supplementation,80 days later,the activities of all kinds of ATPase were significantly improved.The activities of Na+-K+-ATP?Ca 2+ -ATP on membrane of liver,spleen,kidney,brain,cerebrum and lymphoid of invalid calves were significantly lower than that of healthy ones.Conclusion:Copper deficiency had severe effect on the activities of the membrane ATPase of red cell and tissue in calves and restrained the normal physiological function of these tissue. |
