ABSTRACT
OBJECTIVE:To study the effects of 10 kinds of nephrotoxic TCM on three main subtypes(Oat1,Oat2 and Oat3) of kidney organic anion transporter(Oats)in mice. METHODS:A total of 1 840 SPF NIH mice were randomly divided into nor-mal control group(isovolumic pure water),probenecid group(30 kg/mg),sodium carboxymethyl cellulose(CMC)group,Pulsa-tillae radix,Corydalis rhizoma,Aconiti kusnezoffii radix,Aconiti radix,Angelicae pubescentis radix,Gleditsiae spina,Polygo-num cuspidatum,Kansui radix,Platycladi cacumen,Aucklandiae radix high and low dose groups. Mice were treated twice a day for 5 d,ig. After 1 h of the last dosing,they were iv given PAH in tail(30 mg/kg). The PAH pharmacokinetic parameters of the kidney homogenate were determined and the PAH intake in kidney tissue at the time point of 1,5,10,15 and 20 min was detect-ed. The PAH in blood was analyzed by DAS 2.0 software. The grouping and dosing were the same as before,after 1 h of the last dosing,kidney slices were made and put into PAH-buffer. The PAH intake of kidney slices was determined. RESULTS:Compared with normal control group,the t1/2β in C. rhizoma high dose group,A. kusnezoffii high and low dose groups,A. pubescentis high dose group,P. cuspidatum high and low dose groups and P. cacumen group were increased;Vd were all decreased in 10 kinds of TCM high and low dose groups;except for A. pubescentis low dose group,G. spian low dose group and K. radix low dose group, the CL was decreased and AUC0-20 min was increased in all other groups,with significant difference (P<0.01 or P<0.05). Com-pared with normal control group,the content of PAH in kidney tissue in P. radix high dose group,C. rhizoma high dose group,A. kusnezoffii high dose group,A. radix high and low dose groups,A. pubescentis high and low dose groups,G. spina high and low dose groups,P. cuspidatum high and low dose groups,K. radix high and low dose groups,P. cacumen high and low dose groups and A. radix high and low dose groups were increased,with significant difference (P<0.01 or P<0.05). Compared with normal control group,the intake of PAH in kidney slices in C. rhizoma high dose group,A. kusnezoffii high and low dose groups,G. spi-na high and low dose groups,K. radix high dose group,P. ca-cumen high and low dose groups and A. radix high dose group were decreased,with significant difference (P<0.01 or P<0.05). CONCLUSIONS:The 10 kinds of nephrotoxic TCM probably induced kidney injury through inhibiting the Oat1,Oat2 and Oat3 of Oats.
