Growth of Pseudomonas aeruginosa PA01 on isomers of hydroxyproline induced the synthesis of an allohydroxy-D-proline dehydrogenase. The enzyme resembled the D-alanine dehydrogenase of this organism in its association with the particulate fraction and its linkage to oxygen through a cytochrome-containing respiratory chain, but differed from this and other(More)
The modified double-zone SCM technique, developed in these laboratories as an in vitro test for cancer, is based on the differential response to PHA of lymphocytes harvested from two regions of a Ficoll-Triosil gradient. Lymphocyte responses are measured by changes in intracellular fluorescein fluorescence polarisation. We report its continued clinical(More)
The electrophoretic movement of blood cells has been examined with a video image correlator using the signal from a 625 line monochrome television camera attached to the optical arrangement. The diffraction pattern of a cell produces a characteristic signal which can be detected and registered in any television scan line to form the data of the first image(More)

Luminol-enhanced chemiluminescence (CL) was used to examine the response of various leukocyte populations following stimulation with a crude extract of Phaseolus vulgaris, namely phytohaemagglutinin (PHA-C). Populations stimulated included a human peripheral mixed leukocyte preparation (MLP), and purified preparations of lymphocytes, monocytes and(More)
