毒性剂量的顺铂(CP30μmol·kg-1ip)可引起血尿素氮(BUN)升高。硝酸铋(BN)5μmol·kg-1于CP前48和24hse,丙磺舒(Pro)700μmol·kg-1于CP前15,1h及CP后5hig,或BN与Pro二者半量合用,按上述给药,均能抑制CP引起的BUN升高,尤以BN+Pro组抑制作用显著。肾脏光镜和电镜标本显示,CP使肾小管受损严重;BN组,Pro组和BN+Pro组均使CP引起的肾小管受损减轻,尤以BN+Pro组减轻明显。BN2.5-20μmol·kg-1剂量依赖性地诱导小鼠肾脏金属硫蛋白合成。Pro可使CP后24b肾铂含量明显降低;Pro或Pro+BN使尿铂累积排出量增加,血浆铂浓度降低。提示PFO防护CP肾毒性与其减少肾铂分布,增加尿铂排出有关。
Toxic doses of cisplatin (CP30μmol · kg-1ip) can cause elevated blood urea nitrogen (BUN). BN at 5μmol · kg-1 for 48 and 24hse before CP, Prozyl 700μmol · kg-1 at 15h before CP and 5h after CP or half of BN and Pro, Administration, can inhibit CP-induced elevated BUN, especially BN + Pro group was significantly inhibited. Kidney light microscopy and electron microscopy showed that CP damaged renal tubules severely; BN group, Pro group and BN + Pro group all reduced CP-induced tubule damage, especially in BN + Pro group. BN2.5-20μmol · kg-1 dose-dependently induced the synthesis of mouse kidney metallothionein. Pro could significantly reduce the content of 24-week renal platinum after CP; Pro or Pro + BN increased the cumulative urinary platinum excretion and plasma platinum concentration decreased. Tip PF protective CP nephrotoxicity and reduce its distribution of renal platinum, increased urinary platinum discharge.
