A membrane filtration apparatus of the type employed in water bacteriology was used in the assessment of some antimicrobial drugs. Samples of liquid nutrient medium inoculated with a small number of bacteria, to which dilutions of a drug had been added before incubation and again later, were filtered and the membranes washed and incubated on solid medium. By this means differences between bacte...

Granulocyte colony-stimulating factor (G-CSF) has important direct and priming effects on different functions of normal mature polymorphonuclear leukocytes (PMNL). Previous study has shown an alteration in respiratory burst and bactericidal activities of PMNL harvested from children with cancer treated with chemotherapy. The present study evaluates the possibility that recombinant human (rh) G-...

Sulfites and other preservatives are considered food additives to limit bacterial contamination, and are generally regarded as safe for consumption by governmental regulatory agencies at concentrations up to 5000 parts per million (ppm). Consumption of bactericidal and bacteriostatic drugs have been shown to damage beneficial bacteria in the human gut and this damage has been associated with se...

To overcome the poor water solubility of curcumin, a curcumin-?-cyclodextrin (Cur-?-CD) complex was prepared as novel photosensitizer. Fourier-transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), and X-ray diffraction (XRD) were used to verify formation Cur-?-CD. Furthermore, ROS generation capacity photodynamic bactericidal effect measured confirm this Cur-?-CD kep...
