BACKGROUND It is controversial as to whether the development of gastric cancer is influenced by Helicobacter pylori eradication. If eradication itself influences the tumour morphology, this may affect the tumour discovery rate. AIM To investigate the morphological changes in the gastric neoplasm after H. pylori eradication. METHODS We studied 37(More)
Understanding cerebrovascular responses to hyperoxia and hypercapnia is important for investigating exogenous regulation of cerebral hemodynamics. We characterized gas-induced vascular changes in the brains of anesthetized healthy rats using magnetic resonance imaging (MRI) while the rats inhaled 100% O(2) (hyperoxia) and 5% CO(2) (hypercapnia). We used(More)
Studies suggest that neuroprotective effects of normobaric oxygen (NBO) therapy in acute stroke are partly mediated by hemodynamic alterations. We investigated cerebral hemodynamic effects of repeated NBO exposures. Serial magnetic resonance imaging (MRI) was performed in Wistar rats subjected to focal ischemic stroke. Normobaric oxygen-induced functional(More)
A 57-year-old woman was diagnosed as having monoclonal IgG kappa gammopathy of undetermined significance with Sjögren syndrome. Five years later, she was admitted with an increased level of serum IgG and diagnosed as having multiple myeloma. After admission, fever and painful erythema developed. Combined chemotherapy with adrenal cortical steroid diminished(More)
We report a case of Burkitt's lymphoma originating in gluteal muscle tissue. A 61-year-old Japanese man was admitted to our hospital due to painful swelling of the left femur and gluteal region in October 1996. A laboratory examination disclosed elevated levels of serum lactate dehydrogenase and soluble interleukin 2 receptor. Gallium scintigraphy(More)
