| 1 | Protective Effects of Calcium Antagonists on Cadmium-induced Toxicity in Rats显示文摘Protective effects of calcium antagonists, chlorpromazine (CPZ) and nimodepine (NI-MO), on cadmium-induced toxicity were investigated. After giving CdCl2 (0. 44mg Cd/kg,ip), CPZ (5mg/kg, ip) or NIMO (8mg/kg, po) were administered every day to Sprague-Dawley (S. D. ) rats for a week. Then, urinary N- acetyl-β-D- glucosaminidase (NAG ), uri -nary cadmium and bloocl cadmium were measured. The accumulation of cadmium in the kid-ney cortex, content of renal calmodulin, hemoglobin and the ultrastructural damage of proxi-mal convoluted tubules of rats were examined three weeks after the last administration. Re-sults indicated that the calcium antagonists partly protected against toxic effects induced bycadmium in different manners. These data provide further evidence for the new hypothesisthat the cross effect of cadmium and calcium in calmodulin regulated systems may be responsi-ble for the mechanism of cadmium intoxication. ’The results suggested that the calcium antag-onists could be a new and promising approach in the therapy of heavy metaLinduced | YANG XIANFANG YANG YONG-NIAN(Institute of Applied Toxicology, Nanjing the Medical University,Nanjing 210029, China)Abbreviation are Ca, calcium CaM, calmodulin Cd, cadmium CPZ, chlorpromazine Hb, hemogobin NIMO, nimodepine NAG, N-acetyl-β-D- gluco | 1997 | Biomedical and Environmental Sciences1997，10，4： | 3 |
