[2-14C]多菌灵的大鼠透皮吸收和放射自显影研究
Percutaneous absorption and autoradiography of[2-14C]carbendazol in rats
【摘要】 用示踪及放射自显影技术研究了多菌灵的软膏和溶液在大鼠的透皮吸收,作用部位及其在皮肤中的分布。表明多菌灵软膏透入背部皮肤为5.7%,透皮常数为1.86×10-6cm/h;多菌灵溶液透入尾部皮肤为9.8%,透皮带数为29.3×10-6cm/h。该药透皮吸收主要在角质层,作用只局限于渗透部位。
【Abstract】 This paper reported the results of skin absorption and distribution of unguent and solution of [2-14C] carbendazol (MBC) in rats by using radioactive tracer and autorad-iography. It was concluded as: 1) the percentage permeated into skin for unguent was 5.7%, while for solution 9.8%; 2) permeability constant for unguent was 1.86×10-6 cm/h, while for solution 29.3×10-6 cm/h; 3) carbendazol remained mainly in stratum corneum.
