Purified Protein Derivative--PPD.
A 55-year-old physician had a PPD made as part of a clinical evaluation. Laboratory tests were unremarkable and PPD, read in 48 hours, showed an area of induration of 18 mm and an erythema of 51 mm (Panel A). A 2 mm punch biopsy was done in the center of the induration 96 hours after the injection. Histopathology showed an intense perivascular cuffing with macrophages and lymphocytes and edema ...
متن کاملMonitoring contact sensitization to p-phenylenediamine (PPD) by patch testing with PPD 0.3% in petrolatum.
BACKGROUND Being a contact allergen of general relevance, p-phenylenediamine (PPD) is patch tested in the baseline series. However, PPD 1% in petrolatum may actively sensitize. Patch testing with PPD at 0.35% pet. proved to be safe, as far as active sensitization is concerned. OBJECTIVES To determine whether PPD 0.3% pet. reliably detects PPD sensitization. METHODS Patch testing with PPD 0....

متن کاملDistribution of photoperiod-insensitive alleles Ppd-B1a and Ppd-D1a and their effect on heading time in Japanese wheat cultivars
The genotypes of photoperiod response genes Ppd-B1 and Ppd-D1 in Japanese wheat cultivars were determined by a PCR-based method, and heading times were compared among genotypes. Most of the Japanese wheat cultivars, except those from the Hokkaido region, carried the photoperiod-insensitive allele Ppd-D1a, and heading was accelerated 10.3 days compared with the Ppd-D1b genotype. Early cultivars ...
متن کاملPHA and PPD reactivity of lymphocytes in pleural effusions.
The functional properties of lymphocytes in pleural fluid were studied in 23 patients admitted to the hospital for the diagnostic evaluation of a unilateral or bilateral pleural effusion. The in vitro reactivities of the patients' pleural fluid lymphocytes and peripheral blood lymphocytes to phytohemagglutinin (PHA) and to purified protein derivative (PPD) were compared. In most patients with p...
