The effect of Cratylia floribunda lectin on renal hemodynamics and ion transport
Havt, Alexandre; Assreuy, Ana Maria Sampaio; Nascimento, Nilberto Robson Falcão do; Fonteles, Manassés Claudino; Pereira, Lívia de PaulaLectins have been described as glycoproteins that reversibly and specifically bind to carbohydrates. Legume lectins isolated from the subtribe Diocleinae (Canavalia, Dioclea and Cratylia) are structurally homologous with respect to their primary structures. The Diocleinae lectins of Canavalia brasiliensis, Dioclea guianensis and Canavalia ensiformis have been shown to distinctly alter physiological parameters i...
The effect of Cratylia floribunda lectin on renal hemodynamics and ion transport
Havt, Alexandre; Assreuy, Ana Maria Sampaio; Nascimento, Nilberto Robson Falcão do; Fonteles, Manassés Claudino; Pereira, Lívia de PaulaAs lectinas são descritas como (glico)proteínas que se ligam, especificamente e reversivelmente, a carboidratos. Lectinas de leguminosas isoladas da subtribo Diocleinae (Canavalia, Dioclea eCratylia) são estruturalmente homólogas em relação às suas estruturas primárias. Demonstrou-se que as lectinas de DiocleinaeCanavalia brasiliensis, Dioclea guianensis eCanavalia ensiformis alteram diferentemente parâmetros f...
The renal effects of alginates isolated from brown seaweed Sargassum vulgare
Sousa, Alessandra de Paula Alves ,; Barbosa, Paulo Sergio Ferreira; Torres, Márcia Rocha; Martins, Alice Maria Costa; Martins, René DuarteAlginates isolated from Sargassum vulgare , present a strong antitumor activity, associated with kidney reversible damage, as analysed by histopathology of treated animals. In the present study, the renal alteration mechanisms of S. vulgare alginates were investigated using the isolated perfused rat kidney and the isolated perfused rat mesenteric blood vessel methods. The results showed that the effects of Sarg...
