Analysis of water flux in isolated perfused renal ascending and descending thin limbs of Henle's loop under osmotic gradient conditions.A. Compilation of J_v values obtained for descending thin limbs that were untreated (Desc cont) or exposed to 10 mM TEA (Desc TEA), and for ascending thin limbs that were untreated (Asc cont) or exposed to TEA (Asc TEA). B. Compilation of calculated osmotic water permeabilities (P_f) for the same tubules as analyzed in (A). Box plots show the distribution of data values; the gray box encloses 50% of the data points, the error bars show the full range, and the horizontal bar shows the modal value. Data for group means, standard errors and n values are shown below each column. However, since each tubule served as its own control, differences were analyzed by paired T-test and are reported as p < 0.02 (**), p < 0.05 (*), and not significant (N.S.).
