为了研究锌对大鼠成骨细胞膜Ca2+ -ATP酶和Na+ 、K+ -ATP酶活性的影响及其机制,实验设对照组和3个补锌组。采用孔雀绿比色法同步测定膜Ca2+ -ATP酶和Na+ ,K+ -ATP酶活性,以研究Zn2+ 对酶活性的影响以及蛋白激酶C或钙调素特异性抑制剂对Zn2+ 诱导的成骨细胞膜Ca2+ -ATP酶活性的影响。结果表明,Zn2+ 可以显著提高成骨细胞膜Ca2+ -ATP酶活性,但对Na+ ,K+ -ATPase活性无影响;钙调素特异性抑制剂R24571对Zn2+ 诱导的Ca2+ -ATPase活性无影响,钙调素对膜Ca2+ -ATP酶基础活性也无激活作用;蛋白激酶C特异性抑制剂三氟拉嗪可使Zn2+ 诱导的Ca2+ -ATP酶的活性显著降低。因此,锌可能通过蛋白激酶C介导调节成骨细胞膜Ca2+
