Renal alterations promoted by the lectins from Canavalia ensiformis (ConA) and Dioclea guianensis (DguiL) seeds.

The lectin from the seeds of Canavalia ensiformis (ConA) and Dioclea guianensis (DguiL) was tested upon its renal effects using the isolated perfusion rat kidney method. Both lectins (10 microg/ml) affected perfusion pressure and renal vascular resistance, but DguiL showed a much greater action than ConA. However, ConA, but not DguiL, affected potassium tubular transport.
