Oxalate Solution

The characteristics and properties of interlayer materials from 10 non-allophanic (Melanudand) and red yellow soils (Alfisols and Ultisols) from three locations in Japan were studied by chemical extractions and x-ray diffraction (XRD) analyses. Allophane was dissolved from clay samples using 0.15 M acid oxalate solution while silicon and aluminum were dissolved using both 0.15 M acid oxalate and 0.3 M sodium citrate solutions. XRD analyses were done for the treated and untreated samples. For the chemically extracted samples, the clay samples were treated with bicarbonate citrate solution for the removal of iron oxides after the dissolution treatments then saturated with K and Mg ions for XRD analyses. Results of the XRD patternd of the untreated and treated samples indicated the interlayer materials as a hydroxy-interlayered form for vermiculite (HIV). Between the two dissolution treatments, the 0.3 M sodium citrate treatment was found to be more effective in removing the interlayer materials than the 0.15 M acid oxalate treatment by allowing interlayer expansion and collapse.

Inhibitor Of Plasminogen Activator

Fibrinolytic activity in human blood develops after the occurrence of viscous metamorphosis (VM) of platelets. Freshly drawn venous blood was held at room temperature until spontaneous VM of platelets occurred and then introduced into oxalate solution to prevent coagulation. As compared to the control (blood added to anticoagulant before VM) plasma of such samples exhibited increased fibrinolytic activity, detected by increased serial thrombin times. Clots from platelet-rich plasma exhibited an increase in the convergence of branches of the thrombelastograph and a decrease in weight after incubation for 24 hr or more. The increase in branch convergence was roughly proportional to the platelet count and was reduced or absent in thrombocytopenic blood or platelet-poor plasma. Dimethylsulfoxide blocked VM and prevented branch convergence (without preventing clot retraction). Epsilon-aminocaproic acid, an inhibitor of plasminogen activator, blocked or inhibited fibrinolytic activity without arresting VM. This evidence suggests that platelets contain significant proactivator or activator of plasminogen (or a factor which initiates their activity) which is released when VM occurs.
