FIG. 2.

Gross pathology of rabbit duodenal (top), jejunal (middle), or ileal (bottom) loops treated with Ringer's solution containing specified doses (1, 5, 10, or 20 μg) of CPB and TI (150 μg/ml); 20 μg of purified CPB with no TI (CPB/NTI); or 150 μg of TI/ml (control). After treatment, loops were incubated for 6 h. Note that as the dose of CPB increased, the bloody fluid content in all loops receiving both purified CPB and TI also increased. No hemorrhagic fluid was observed in loops receiving an injection of CPB alone (no TI) or TI alone (no CPB). The data shown are representative of six repetitions.
