Primary low-grade B cell non-Hodgkin's lymphoma of MALT type simultaneously arising in the colon and in the lung: report of a case.

zone B cell lymphoma of mucosa-associated lymphoid tissue type according to the Revised European American Lymphoma classification). Other mucosa-associated lymphoid tissue-type lymphomas arise in the salivary glands, thyroid gland, and in the lung (bronchus-associated lymphoid tissue). Here, we report the first case of a monoclonal mucosa-associated lymphoid tissue lymphoma with simultaneous manifestation in the colonic and bronchial mucosa in a 62-year-old patient.

Key importance of the Helicobacter pylori adherence factor blood group antigen binding adhesin during chronic gastric inflammation.

Helicobacter pylori has been assigned as a class I carcinogen because of its relation to gastric adenocarcinoma. Chronic H. pylori infection may lead to severe gastritis, glandular atrophy (AT), and intestinal metaplasia (IM).

Cardiac surgery in patients with previous carcinoma of the breast and mediastinal irradiation: is the internal thoracic artery graft obsolete?

Background: The increasing number of patients of more advanced age undergoing cardiac surgery means the number of those with previous curative (relapse free) mastectomy and irradiation of the chest is also increasing. A higher incidence of postoperative complications such as sternal infection in these patients is considered possible. Furthermore the question of whether mediastinal irradiation leads to a relevant internal thoracic artery (ITA) gaft damage remains unclear.

Expression of plakoglobin in renal cell carcinoma.

Little is known about the role of molecules involved in cell-cell interactions during the progression of renal cell carcinoma (RCC). We investigated the expression of plakoglobin (a component of the cadherin-catenin adhesion system) in 94 samples of normal kidney tissue from patients with RCC, in 109 primary renal cell carcinomas and in 16 metastases by immunohistochemistry. Expression of plakoglobin was significantly diminished in tumor tissue, particularly in metastatic lesions, as compared to normal kidney tissue (p < 0.

Intrarenal distribution of organic osmolytes in human kidney.

The distribution pattern of renal organic osmolytes in surgically explanted human kidneys was investigated and compared with that of untreated Sprague-Dawley rats (Uosmo = 1186 mosmol/kg H2O). Sorbitol, myo-inositol, glycerophosphorylcholine and betaine were measured by liquid chromatography (HPLC) in homogenates of five different kidney zones from the cortex towards the papillary tip. All four organic osmolytes were detected as in human as in rat kidney.
