Background: Plasminogen is one of the compounds derived from human plasma. Activation of plasminogen produces plasmin. Plasmin is able to lyse fibrinogen, fibrin, and some other human plasma proteins. The aim of the present work was to study the separation of human plasminogen by affinity chromatography using gel lysine Sepharose. Materials and Methods: Normal human plasma was used as the...

cant correlation between plasma aldosterone and plasma potassium concentration (r = +0.74, P < 0.001) and between changes in the concentration of plasma aldosterone occurring in individual patients and the corresponding changes in plasma potassium concentration (r = +0.52, P < 0.01). There was no significant change in plasma sodium concentration, and plasma corticoid concentration, which was mo...
