Fig. 4. Glucose filtration (µmol kg1 h1)
vs glucose reabsorption (µmol kg1
h1) in fish infused with glucose-only or phlorizin and
glucose together. Points are values for individual fish at different times,
not mean values. See text for details. Regression equations: for glucose only
group, y=0.200x35.471 (r2=0.8489)
and for glucose + phlorizin treated group, y=0.031x+58.047
(r2=0.018).
