This paper studies the modulation by bradykinin of the ouabain-insensitive Na+-ATPase activity in both renal cortex homogenate and basolateral membrane from proximal tubule. The increase in bradykinin concentration from 10-14 to 10-10 M stimulated the ouabain-insensitive Na+-ATPase activity in cortex homogenates about 2.2-fold, but inhibited the enzyme(More)
Lectins are carbohydrate-binding proteins of non-imune origin. This group of proteins is distributed widely in nature and they have been found in viruses, microorganisms, plants and animals. Lectins of plants have been isolated and characterized according to their chemical, physical-chemical, structural and biological properties. Among their biological(More)
