Abstract
The renal tubules of the shark actively reabsorb urea. They also can reabsorb acetamide and methylurea, but there is no evidence for active reabsorption of thiourea. The specificity of the transport system thus appears to be different from the urea secretory system in the frog in which thiourea is secreted but acetamide and methylurea are not secreted.
摘要
鲨鱼的肾小管会主动重吸收尿素。它们也能重吸收乙酰胺和甲基脲，但没有证据表明硫脲会被主动重吸收。因此，这种转运系统的特异性似乎与青蛙的尿素分泌系统不同，在青蛙中，硫脲会被分泌，但乙酰胺和甲基脲不会被分泌。
