In vitro Lymphocytic Stimulation with PPD
Respiration, 2009One-way mixed lymphocyte reaction with PPD in healthy volunteers and in patients suffering from tuberculosis gave us no correlation with the degree of Mantoux sensitization. There were two major indications for further study: (a) An adequate stimulation index (SI) against PPD in vitro in tuberculosis patients correlated with satisfactory treatment ...

Geographic variations in the prevalence of sensitivity to PPD-S and PPD-B in Western Australia
Tubercle, 1967Summary Between 1960 and 1966 comparative Mantoux testing using PPD-S and PPD-B was performed on 11,885 school children living in different areas in Western Australia. PPD-B is prepared from Battey mycobacteria and was diluted before delivery to us to correspond in protein and nitrogen content with the PPD-S. The proportion of school children giving

The duration of periods to heading has been compared in lines which carry various Ppd genes from different institutions. Test for allelism has been conducted between these lines. Ppd-??1?? gene is allelic to Ppd3 gene of near isogenic line Mironovskaya 808 (the set of SGI). In the set of SGI lines Ppd1 gene is allelic to Ppd-A1a..

Pediatrics, 1967
EPIDEMIOLOGIC studies and prophylaxis trials over the last decade have radically altered our concepts of tuberculosis. Some old ideas have gone out the window and some important new methods have been developed. Vigorous application of these newer concepts will speed the eradication of tuberculosis in this country.

Occurrence of p-phenylenediamine antioxidants (PPDs) and PPDs-derived quinones in indoor dust
Science of The Total EnvironmentThe p-phenylenediamine antioxidants (PPDs) have been widely detected in various dust samples. Nevertheless, the knowledge on occurrence of their environmental transformation products, PPD-derived quinones (PPDQs), in indoor dust remains limited. In this study, indoor dust samples (n = 97) were collected from Hangzhou, China, and analyzed for PPDs and ...
