Inhibitory effects of RG-tannin on CT-induced fluid accumulation in the
rabbit ileal loop. Test was carried out as described in
Materials and Methods, and the rabbit was killed after
18 h. Loops contained the indicated amounts of CT and RG-tannin.
1, no additions; 2–7, 250 ng of CT; 3 and 8,10 μg of RG-tannin; 4, 3
μg of RG-tannin; 5, 1 μg of RG-tannin; 6, 300 ng of RG-tannin; and
7, 100 ng of RG-tannin. Experiment was replicated five times.
