The metal allergens mercuric chloride and nickel sulfate were found to stimulate DNA synthesis of different in vitro cultured lymphoid cells from newborn guinea pigs. In contrast to earlier findings in adult animals (where spleen cells were most consistently stimulated), in newborn animals thymocytes were the most clearly stimulated lymphoid cells. When separating thymocytes by peanut agglutini...

Dihydroartemisinin and other artemisinin derivatives are relatively ineffective against Plasmodium falciparum infecting a-thalassemic erythrocytes, namely hemoglobin (Hb) H or HbH/Hb Constant Spring erythrocytes, as compared with those infecting genetically normal erythrocytes. The variant erythrocytes accumulate radiolabeled dihydroartemisinin to a much higher extent than the normal ones, and ...

Effect of Septilin, an Ayurvedic formulation proven to be effective in the therapy of chronic infections, was investigated on the phagocytic system and humoral response in rats and mice. Septilin exhibited significant protection in E. coli-induced abdominal sepsis in normal mice and in Staphylococcus aureus-induced sepsis in neutropenic mice. It significantly reduced the viable E. coli cells wh...
