| 摘 要： | 研究了稀土离子对红细胞膜Ca2 －ATP酶活性和ATP分解的影响．实验结果表明，0．01mmol·dm-3的La3 、Sm3 、Y3 对红细胞膜Ca2 －ATP酶有激活作用，Y3 的激活作用小于Sm3 、La3 ．当溶液中La3 、Sm3 、Y3 浓度增大时，稀土离子对Ca2 -ATP酶的激活作用反而减弱，抑制作用增强．稀土离子能加速溶液中ATP的分解，溶液中稀土离子浓度越高或作用时间越长，ATP分解越多．

| Abstract: | It was studied that the effects of rare earths on the activity of crythrocytic mem-brane Ca2 -ATPase and the ATP decomposition in solution in this paper. The resultsshowed that 0. 01mmol. dm-s La3 ,Sm3 ,ys stimulated the activity of crythrocytic mem-brane Caz -ATPase, but the stimulation of Y3 was lower than that of La3 ,Sm3 . WhenLa3 ,Sm3 , Y3 concentration increased in medium,their stimulation to Ca2 -ATPase activ-ity decreased,and the inhibition strengthened. The rare earth ions could activate the ATP de-compositon in solutibn,and the more their concentration or the longer the action time,themore the ATP decomposition. |
