Bacteroids of 83 strains of rhizobia in the nodules of one of three Lotus species have been examined with the electron microscope. Nine different inclusion bodies are described and their presence or absence in the bacteroids is listed. There is complete agreement between the presence or absence of polyphophate bodies and of prominent nuclear material and(More)
Six strains of Rhizobium, present as bacteroids, in Lotus nodules were studied by electron microscopy. Three inclusion bodies frequently detected are described and their distribution among the strains is given. Cytochemical techniques indicated that they have, as principal components, polyphosphate, lipid and neutral polysaccharide, probably glycogen,(More)
Four PN/n mice between 12 and 17 months of age had fibrinoid necrosis of the renal arteries, but 32 mice up to the age of 17 months showed no consistent change in the media or intima of the renal arteries although perivascular cuffing with round cells was prominent from 9 months of age. Glomerulitis, indicated by increase in the mesangium on light(More)
In a phase I clinical trial Zoladex was used as first line hormonal therapy in premenopausal women with advanced breast cancer. Patients on progression of their disease underwent surgical oöphorectomy. The histology of ovaries from 23 women treated with Zoladex has been compared with the ovaries from 34 patients who, before the clinical trial of Zoladex,(More)
