The case is described of a 36 year old woman who presented with a large left sided haemothorax. A thoracic computed tomographic (CT) scan suggested there was a bony outgrowth arising from the fourth rib. This was resected surgically and found to be an osteochondroma which was surrounded by blood clot. No definite site of bleeding was identified, but it is thought that the tumour may have traumatised the lung, the pericardiacophrenic artery, or the superior pulmonary vein, resulting in life threatening haemorrhage. 相似文献

This study delineates the role of angiotensin II type I (AT1) receptor in the remodeling of Syrian cardiomyopathic hamsters.
Twelve cardiomyopathic (T0-2) hamsters received L-158,809 treatment ad libitum in their drinking water (27 μg/ml) and 9 cardiomyopathic
and 9 normal F1-B hamsters received tap water from 1 to 4 months of age. Although pharmacologically effective with regard
to complete suppression of the blood pressure response to angiotensin II infusion, L-158,809 did not diminish the progression
or severity of cardiomyopathy. Heart weight/100 g body weight and left ventricular wall thickness adjusted for body weight
of both L-158,809 and cardiomyopathic control hamsters did not differ and exceeded those of F1-B controls (p < 0.05). Myocardial
material properties (e.g., stiffness and density) of cardiomyopathic hamsters treated with L-158,809 were not affected. Thus,
the progression of fibrosis, calcification, and necrosis in T0-2 cardiomyopathic hamsters was not sensitive to AT1 receptor
blockade.

Identification of Marek's disease virus-infected lymphocytes is essential for a full understanding of the pathogenesis of Marek's disease. This paper describes the development of a simple, quantitative and reproducible flow cytometric technique for the identification of the phenotype of Marek's disease virus-infected lymphocytes. The method is based upon the detection of the Marek's disease virus-specific phosphoprotein pp38, in saponin-permeabilized lymphocytes, using the monoclonal antibody BDI, and the identification of the phenotype of pp38(+) lymphocytes using monoclonal antibodies against lymphocyte surface markers. pp38 expression in the spleen was demonstrated in the cytolytic phase of infection. The mean proportion of pp38(+) lymphocytes at 4 days post-infection was 0.43%. Of these, 95% were B lymphocytes, while only 4% were T lymphocytes (both CD4(+) and CD8(+)). The potential of the technique for the investigation of the cytolytic phase of Marek's disease is discussed. 相似文献

AIMS: To determine the prevalence of Pseudomonas fluorescens on the arms of blood donors, and to elucidate one possible cause for its predominance (60% of cases during 1980-89) in exogenous post transfusion septicaemia (PTS). METHODS: Skin swabs were taken from the arms of 782 blood donors and cultured on to heated blood agar. After incubation, Oxidase reagent and the Gram stain were used to select non-fermentative Gram negative rods, which were then subcultured and identified using the Analytical Profile System (API) 20 NE system. RESULTS: Non-fermentative Gram negative rods were found on the arms of 11.7% of donors, Pseudomonas spp on 1.0%, and Ps fluorescens on the arms of 0.3% of donors. CONCLUSIONS: This evidence emphasises the absolute requirement for efficient skin cleansing of blood donors' arms to minimise the risk of exogenous PTS. 相似文献
