Ito cells in lysosomal storage disorders
Springer Science and Business Media LLC - Tập 46 - Trang 13-19 - 1984
M. Elleder
An ultrastructural study was performed in a series of liver biopsies from patients with various lysosomal storage diseases to evaluate the extent of lysosomal hypertrophy and hyperplasia in Ito cells (ICs). In previous studies this has been considered to be absent or only rudimentary. Lysosomal storage was recognized by the presence of storage cytosomes surrounded by limiting membranes and by the ...... hiện toàn bộ
Light and immunoelectronmicroscopic study of Hodgkin’s disease: Evidence of immunoglobulin synthesis by tumor cells
Springer Science and Business Media LLC - Tập 37 - Trang 109-124 - 1981
Malgorzata J. Gladkowska-Dura, Wieslaw T. Dura, Warren W. Johnson
The direct immunoperoxidase technique with peroxidase-conjugated F(ab′)2 fragments was used at the light and electron microscopic levels to identify intracytoplasmic immunoglobulin (CIg) components in malignant cells of Hodgkin’s disease. In each of the 27 cases studied, Hodgkin and Reed-Sternberg cells contained either IgG or IgM, with both light chains often present simultaneously. The number of...... hiện toàn bộ
Kháng thể trong tế bào chất ở tăng sinh bạch huyết hạch khổng lồ (khối u Castleman) Dịch bởi AI
Springer Science and Business Media LLC - Tập 38 - Trang 239-246 - 1981
Wieslaw T. Dura, Olga Mioduszewska, Anna Porwit-Ksicażek
Các đặc điểm miễn dịch mô học đã được nghiên cứu trong 6 trường hợp tăng sinh bạch huyết hạch khổng lồ (GLNH) và các đặc trưng của kháng thể trong tế bào chất (CIg) đã được so sánh với những đặc trưng của u lymphoma dạng nang và tăng sinh bạch huyết hạch dạng nang không đặc hiệu. Bằng cách sử dụng kỹ thuật peroxidase-antiperoxidase (PAP), kết quả cho thấy GLNH bao gồm một quần thể tế bào sản xuất ...... hiện toàn bộ

Mitoses and binucleated cells in perinatal human hearts
Springer Science and Business Media LLC - Tập 48 - Trang 59-67 - 1985
Gerhard Schmid, Peter Pfitzer
Cells from hardened formalin-fixed human hearts were isolated with potash lye. In perinatal hearts mitoses and evidence of irregular chromosomal movement such as chromatin bridges and micronuclei were observed in small numbers during normal development. A quantitative analysis of binucleated cells shows 8.8 ± 5.3% in the left and 11.7 ± 4.0% in the right ventricular wall around the time of birth. ...... hiện toàn bộ
Ultrastructural observations in the carbonyl iron-fed rat, an animal model for hemochromatosis
Springer Science and Business Media LLC - Tập 53 - Trang 208-217 - 1987
T. C. Iancu, R. J. Ward, T. J. Peters
Rats fed a carbonyl iron-supplemented diet for 4–15 months were studied for iron content and morphologic changes in the liver, spleen, intestinal mucosa, pancreas and heart. All organs had an increased iron content measured by atomic absorption, with the highest concentrations in the liver and spleen. The periportal distribution of stored iron in the liver was similar to that in human hemochromato...... hiện toàn bộ
Spatial distribution of Langerhans’ cells and T-lymphocyte subpopulations in human tympanic membrane and aural cholesteatoma
Springer Science and Business Media LLC - Tập 52 - Trang 143-152 - 1986
C. M. van Dijk, C. E. Visser, J. E. Veldman
Immunohistochemical analysis of human cholesteatoma matrices revealed the presence of Langerhans’ cells and T-lymphocytes. Through cell-to-cell interaction, Langerhans’ cells probably play a key role in skin-related disorders, including cholesteatomas. They probably originate from a mobile cell population of monocyte origin and migrate into and out of the body’s lining. Their custodial function is...... hiện toàn bộ
Unbuffered osmium staining of cell organelles: alterations induced by cell injury
Springer Science and Business Media LLC - Tập 45 - Trang 273-287 - 1984
Louis Marzella, Qianchun Yu, Wolfgang Mergner, Benjamin F. Trump
We have studied the localization of osmium reduction products to investigate the functional state of organelles as well as organelle interrelationships during cell injury. In normal hepatocytes osmium deposits of variable intensity are seen in nuclear envelope, endoplasmic reticulum, Golgi cisternae and vesicles and lysosomes. Buffering of osmium with s-collidine (pH 7.4) prevents the deposition o...... hiện toàn bộ
Atypical T cells in rheumatoid synovial membranes
Springer Science and Business Media LLC - Tập 24 - Trang 19-26 - 1977
E. de Vries, A. W. F. M. van Leeuwen, L. B. A. van de Putte, G. J. M. Lafeber, C. J. L. M. Meyer
Atypical mononuclear cells (AMC) with Sézary-cell-like morphology were demonstrated to be present in rheumatoid synovial membranes. These cells have exclusively T cell membrane characteristics, like identical cells previously found in rheumatoid synovival fluids. AMC were predominantly present in transitional areas between nodular lymphocytic aggregates and plasma cell rich areas. In ultrathin sec...... hiện toàn bộ
Acute changes occurring in the intestinal mucosae of rats given a single injection of 1,2 dimethylhydrazine
Springer Science and Business Media LLC - Tập 36 - Trang 47-57 - 1981
J. P. Sunter, D. R. Appleton, A. J. Watson
In the long term, administration of dimethylhydrazine (DMH) to rats results in the development of tumours in both small intestine and colon. This study has been undertaken in order to document the sequence of changes occurring in the intestinal mucosa in the first 108 h following a single subcutaneous injection of DMH. After a lag of several hours there is evidence of damage to cells in the prolif...... hiện toàn bộ
