With the aid of three basic organic compounds, 2-pyrazinoylguanidine, 3-amino-2-pyrazinoylguanidine, and 3,5-diamino-6-fluoro-2-pyrazinoylguanidine, urea was shown to be secreted by the renal tubules of the dog both from the lumen and into the lumen independent of urine flow.
借助三种基本有机化合物,即2-吡嗪甲酰胍、3-氨基-2-吡嗪甲酰胍和3,5-二氨基-6-氟-2-吡嗪甲酰胍,研究表明尿素可由犬肾小管从管腔分泌至管腔内外,且与尿流无关。
