Calotropis gigantea, the giant milkweed, is traditionally used for the treatment of cancer and in Ayurvedic medicine as an anti-helminthic, anti-pyretic, and anti-malarial agent. Poecilocerus pictus, an orthopteran insect, feeds on C. gigantea and both are known to possess cardiac glycosides. The increasing reports on the specific cytotoxicity of cardiac glycosides on human tumor cell lines led us to attempt characterization and comparative evaluation of cardenolides in both the insect and plant extracts for their anti-tumor and apoptotic potential...

The effects of the ethanol extract of the root of Plumbago zeylanica on key enzymes of glycolysis and other biochemical parameters were studied in the rat. The results show that thigh muscle hexokinase, phosphofructokinase, pyruvate kinase and lactate dehydrogenase activities were significantly reduced (p < 0.05) by 12.07%, 51.02%, 24.32% and 25.16% respectively in rats treated with the ethanol extract of Plumbago zeylanica when compared with the controls. Serum pyruvate and lactate were significantly lowered in the experimental rats by 23...

Non-viral gene therapies are currently under development that employ drug-delivery methods for targeting genes to selected cells in the body, where they express therapeutic gene products. Various methods have been described for non-viral gene therapy, ranging from the direct intramuscular injection of purified DNA to the systemic administration of formulations comprising DNA and lipids, proteins, peptides, or polymers. Products for non-viral gene therapies are designed both for direct administration to patients by conventional routes and for expression of a therapeutic product over a finite period of time in a manner similar to conventional medicines...

Hematopoietic growth factors have already had an enormous impact on transfusion practice by eliminating or reducing the need for red blood cell transfusions in a variety of anemic states characterized by an absolute or relative decrease in erythropoietin. In addition, GM-CSF and G-CSF have stimulated the production of autologous neutrophils in febrile neutropenic patients in whom granulocyte transfusions had been considered ineffective. With the discovery of c-Mpl ligand and the promising results obtained with IL-11 and IL-3, a combination of growth factors that successfully stimulate platelet production may soon be identified...
