-Levamisole, which has immunostimulant activity, is now being used to treat some forms of cancer. We report that the drug enhances granulocyte colony formation. The mechanism of action appears to be partly through modulation of molecules on cell membranes. The molecular content of colony-stimulating activity (CSA) released into leucocyte-conditioned medium by cells of leukaemic and some preleuk...

in this study, a crude leishmanial antigen, was prepared by sonicating leishmania major promastigotes used to induce immunity in balb/c mice against cutaneous leishmaniasis. correlation between the route of antigen injection and the efficacy of induced protection was examined. to enhance the effectiveness of the antigen, an immunostimulant drug, daraprim (pyrimethamine), was administered simult...

Over the last years, there has been an increasing trend towards use of environmentally friendly processes to synthesize nanomaterials. In case nanomedicine, bionanofactories with associated biological properties, such as seaweed, emerged a promising field work due possibility they open for both preservation those properties in nanomaterials synthesized and/or reduction their toxicity. present s...
