Abstract
Counterflow experiments demonstrate the existence of urea counter-transport on the epithelium luminal surface. This phenomenon disappears when 10(-4) M phloretin is added to the perfusion fluid. Moreover counterflow experiments made using thiourea as elicitor, demonstrate that the phenomenon is specific for the urea.
摘要
逆流实验证明在上皮细胞腔面存在尿素逆向转运。当向灌注液中加入10⁻⁴ M根皮素时，这种现象消失。此外，用硫脲作为诱导剂进行的逆流实验表明，该现象对尿素具有特异性。
