This study was published and made available on the Web in November 2003, by the British Medical Association's Health Policy and Economic Research Unit. The study aims to provide a critical appraisal of the New Deal monitoring process and access methods used from the perspectives of junior doctors and medical ...

Tumours of the vermiform appendix were studied. The majority proved to be carcinoid tumours of the usual argentaffin-positive type but a substantial minority, generally tumours of minute size, were found to have a somewhat different histological pattern and were argentaffinnegative. Some contained argyrophil granules. The non-argentaffin tumours are considered to ...

The mammalian and avian toxicities of N-tritylmorpholine (Frescon, WL 8008), a compound active against the snails that are the intermediate hosts of schistosomes, are reported. The acute oral, acute percutaneous, dermal irritation, sensitization and subacute toxicity methods used are described and the results obtained are discussed.The acute oral toxicity of ...

The intravascular life-span of leukocytes labelled in vitro with radioactive di-isopropylfluorophosphate was studied in 12 patients with chronic myelogenous leukemia (CML). In relapse, leukocyte specific activity (LSA) disappeared slowly; in remission, LSA curves approached normal and only a small proportion of LSA disappeared slowly. The level of maturation of the ...

Polynoxylin and noxythiolin (Anaflex and Noxyflex) have been recommended for the treatment of certain bacterial infections. Both compounds were shown to release formaldehyde. Detailed studies with noxythiolin showed that it decomposed in solution to liberate most of its formaldehyde, and that solutions of formaldehyde of the appropriate strength gave zones ...

The study of the fluorescence of chlorophyll a offers a useful approach toward better understanding of the primary act of photosynthesis. This paper describes new measurements of the decay of chlorophyll a fluorescence in vivo, made with a considerably improved oscilloscopic-display technique. The main result is the identification of two ...

Hemophilus pleuropneumoniae is highly pathogenic for swine when given intranasally. As few as 100 organisms induce characteristic porcine contagious pleuropneumonia (PCP) and, when as many as one-half million are given, the infection usually proceeds to a fatal termination. While the organism is highly pathogenic when introduced by way of the ...

The International Opacity Reference Preparation is a polydisperse suspension of glass particles, the size distribution of which it is hardly possible to reproduce. However, by mixing glass particles of different size distributions it seems practicable to prepare a suspension which is turbidimetrically almost identical to the International Opacity Reference Preparation. ...

The authors describe the bilharziasis endemic areas in north-eastern Brazil, giving the rainfall and general characteristics of the climate. The life-cycles of the two snail vectors-Australorbis glabratus and Tropicorbis centimetralis-in Pernambuco are described. Considerable attention is given to the effects on the snails of the annual drought, which causes many ...

The coagulase-reacting factor (CRF) of human plasma has been purified, concentrated, and largely freed of prothrombin activity by Seitz filtration, absorbtion on hyflo-amphogel columns, controlled phosphate buffer elution, and fractional ammonium sulfate precipitation. The purified CRF preparations localized between the beta and the gamma globulin position on paper electrophoresis, and ...

Kernicteric pigment was extracted by means of chloroform from the brains of 3 infants. Solutions of it gave a positive diazo reaction, and, as determined electrophotometrically, gave maximum absorption of light having a wavelength of 425 mmicro, being identical in these properties with chloroform solutions of crystalline mesobilirubin. Experimental kernicterus ...

1. Adsorption of ovalbumin on the latex surface was in excess of the quantity required to produce coverage of the surface over most of the protein concentrations range which was investigated. 2. "S" shaped isothermals which probably indicated multilayer adsorption were obtained. 3. The quantity of ovalbumin required to produce ...
