Adult New Zealand white rabbits were experimentally infected with a parasitic African hemoflagellate, Trypanosoma congolense, and were subsequently tested for in vivo and in vitro aspects of cell-mediated immune function. Chronically infected rabbits were sensitized to mycobacterial protein and skin-tested with purified protein derivative; all infected animals demonstrated much milder skin-test...

The immunomodulation determined by natural killer cell activity, delayed-type hypersensitivity to purified protein derivative and phytohemagglutin, and phenotypic changes of peripheral blood lymphocytes was characterized in 12 patients with epithelial ovarian cancer who received adoptive transfer of tumor-infiltrating lymphocytes (TILs) after cisplatin-containing chemotherapy (TIL group). As a ...

High-dose Mycobacterium bovis-infected mice fed a vitamin A acetate-supplemented diet developed a positive skin reaction to purified protein derivative of mycobacteria, and their spleen cells showed an increased IL-2 production in vitro.

What methods would you choose apart from purified protein derivative (PPD) skin test and culture for acid-fasting bacilli (AFB) to make a clinical diagnosis of pulmonary tuberculosis (TB) in an aged patient with possible TB? These are two cases TB, that occurred persistent low-grade fever, fatigue anorexia due mild toxemia tuberculosis. A final was established on the basis toxemia(low-grade fev...

prostate-specific antigen (psa) was purified to homogeneity from human seminal plasma by ion-exchange chromatography on a cm-sephadex c-50 and by gel filtration on a sephacryl s-200 column. a single 33-kda protein band appeared in sds-page. high pressure liquid chromatography (hplc) of the purified protein produced a single peak, while isoelectric focusing demonstrated the presence of five diff...

Postpartum depression (PPD) is associated with debilitating effects on mothers and their infants. A previous history of depression is considered the strongest risk factor for PPD. Depressed individuals recall more negative than positive content and higher levels of stress hormones released during encoding are associated with enhanced recall of emotional stimuli. This study examined the impact o...
