There was a significant increase in circulating monocyte membrane permeability for calcium and cytosolic calcium concentration following reperfusion in human OLT. This was independent of extracellular calcium concentration. These results are consistent with WBC activation by reperfusion and could be implicated in the systemic reperfusion syndrome seen in OLT in humans.

The roots of Holostemma annularis K. Schum (Asclepiadacae) are used in traditional medicine to treat diabetes. This medicinal plant, widely used in more than 34 ayurvedic preparations, was evaluated in a high fructose diet in induced insulin resistance and in C57BL/6J ob/ob diabetic mice for its antidiabetic activity. Graded doses of both chloroform and methanolic extracts of the roots of H. annularis were administered to normal and experimental diabetic rats for 21 days. Serum glucose, triglycerides, cholesterol levels and total protein in urine were analyzed. Significant results were observed in the estimated parameters. These data justify the use of the plant in the treatment of diabetes mellitus and is a potential source for the isolation of new active agents for diabetes mellitus.
