VARIATION OF INTRACELLULAR FREE CALCIUM CONCENTRATION IN ARISTOLOCHIC ACID I INDUCED APOPTOSIS IN LLC PK1 CELLS AND INHIBITION OF APOPTOTIC DAMAGE BY LACIDIPINE
To examine the changes of intracellular free calcium concentration([Ca 2+ ] i)in aristolochic acid I(AAI) induced apoptosis in LLC PK1 cells,and the effects of Lacidipine(a calcium antagonist)on the changes of [Ca 2+ ] i and apoptosis induced by AAI. METHODOLOGY LLC PK1 cells were treated in different groups:(a)normal,without treatment;(b)with AAI alone(0 04 g/L);(c)with Lacidipine alone(10,10 2,10 3 ng/L);(d)with AAI(0 04 g/L)plus Lacidipine(10...
