Clearance of mannitol, Cr-EDTA, and inulin from luminal perfusates containing either 30 mmol/L mannitol or glucose (perfusion rate, 0.5 mL/min) and of mannitol and Cr-EDTA (perfusion rate, 0.2 mL/min). The mannitol values (perfusion rate, 0.5 mL/min) are the compiled data from the 51Cr-EDTA/14C-mannitol and 14C-mannitol/3H-inulin series. Bars denote ±SE. Significances between values and number of observations (n) are shown in Table 1.

Clearance of mannitol, Cr-EDTA, and inulin from luminal perfusates containing either 30 mmol/L mannitol or glucose during nicotinic receptor blockade by hexamethonium (10 μg/kg intravenously) administered every 45 minutes. The mannitol values are the compiled data from the 51Cr-EDTA/14C-mannitol and 14C-mannitol/3H-inulin series. Bars denote ±SE. Significances between values and number of observations (n) are shown in Table 2.

Relationship between net fluid transport and clearance of the different permeability probes in all series in this study. The exact values and SE values are shown in Tables 1 and 2. The linear regression equation for clearance of Cr-EDTA is y = 0.09x , for mannitol with KM solution y = 0.33x , and with KG solution y = 1.15x
