Biological activities of a lectin from Bothrops jararacussu snake venom.

Snake venoms contain saccharide-binding lectins. In this work, we examined the biological activities of a lectin (BjcuL) purified from Bothrops jararacussu snake venom by chromatography on non-derivatized Sepharose 4B and Sephacryl S-200 HR. The protein, a homodimer with subunits of 14.

Hypertension plus diabetes mimics the cardiomyopathy induced by nitric oxide inhibition in rats.

Study Objectives: We compared the myocardial lesions caused by the long-term inhibition of nitric oxide (NO) biosynthesis with those associated with renovascular hypertension (two-kidney, one-clip model [2K-1C]) and superimposed streptozotocin-induced diabetes mellitus (DM).

Design: Prospective trial.

Setting: University laboratory.
