The Value of Immunocytochemistry in Differentiating High-Grade: Lymphoma from Other Anaplastic Tumours: A study of anaplastic tumours from 1940 to 1960.

Immunocytochemistry is now established in many histology laboratories for diagnostic purposes and is routinely used in ascribing an origin to poorly differentiated tumours. This raises the question of whether traditional morphological skills are being abandoned in favour of new technology and, if so, whether that is justified. Twenty-three lymph node biopsies diagnosed as anaplastic carcinoma, reticulosarcoma or unclassifiable tumour between 1940 and 1960 (when immunocytochemistry was not available) were retrieved from the archives of the Radcliffe Infirmary.

Giant cell myocarditis associated with lymphoma: an immunocytochemical study.

A case of giant cell myocarditis in a patient with non-Hodgkin's lymphoma is reported. To our knowledge, this is a previously unrecorded association and supports the hypothesis that the aetiology of giant cell myocarditis is related to a changed immune state. Immunohistochemical investigation of this case with a panel of monoclonal antibodies against a range of leucocyte and muscle antigens supports the view that the giant cells have a histiocytic rather than a myogenic origin.

Metabolite production during the biodegradation of the surfactant sodium dodecyltriethoxy sulphate under mixed-culture die-away conditions.

Sodium dodecyltriethoxy sulphate (SDTES), either pure or as a component of commercial surfactant mixtures, underwent rapid primary biodegradation by mixed bacterial cultures in OECD screen and river-water die-away tests. Inoculation of [35S]SDTES-containing solutions with OECD screen test media acclimatized to surfactants or their degradation products led to production of various 35S-labelled glycol sulphates and their oxidation products, all known to occur during degradation of [35S]SDTES by pure bacterial isolates. Triethylene glycol monosulphate was the major catabolite together with smaller amounts of di- and monoethylene glycol monosulphates implying, by analogy with pure cultures, that ether-cleavage was the major primary biodegradation step.

A comparative study of the biodegradation of the surfactant sodium dodecyltriethoxy sulphate by four detergent-degrading bacteria.

The 35S-labelled metabolites produced during biodegradation of sodium dodecyltriethoxy [35S]sulphate (SDTES) by four bacterial isolates were identified and quantified. All four isolates used ether-cleavage as the predominant primary degradation pathway. In two of the organisms, the etherase system (responsible for approx.

Initial Stages in the Biodegradation of the Surfactant Sodium Dodecyltriethoxy Sulfate by Pseudomonas sp. Strain DES1.

The biodegradation of the surfactant sodium dodecyltriethoxy sulfate by Pseudomonas sp., strain DES1 (isolated from activated sludge plant effluent) has been studied. Growth of the organism when the S-labeled surfactant was present as the sole source of carbon and energy led to the appearance in the culture fluid of five S-labeled organic metabolites.

Pneumatoceles following hydrocarbon ingestion. Report of three cases and review of the literature.

Three cases of pneumatocele formation secondary to hydrocarbon ingestion are reported and analyzed along with 12 from the literature. The cases display a spectrum of clinical severity. After a period of 3 to 15 days, during which most patients became asymptomatic, pneumatoceles were noted radiologically, usually as an unexpected finding on follow-up roentgenograms.
