A 65-year-old male, having symptoms suggestive of pulmonary malignant tumor, underwent video-assisted thoracic surgery (VATS). Surgery revealed a solid tumor originating from the thoracic wall, with many small solid tumors in the thoracic wall and diaphragm near the tumor. The intraoperative observation of a frozen section typed the tumor as carcinoid; however, hematoxylin-eosin staining and im...
An immunohistological survey of 28 full-term human placentas has demonstrated deposits of IgG, beta1C, beta1E, and fibrinogen/fibrin in areas of fibrinoid necrosis and on the trophoblast basement membrane in approximately 35% of placental villi. Traces of IgM were detected at similar sites in 18 of 28 full-term placentas. In 11 specimens of immature placentas (10-18 wk gestation) traces of IgG ...
IN principle, it can be stated that initiation of histogenesis is preceded or accompanied by synthesis of molecular species, specific for cells belonging to a particular type of tissue. It has long been suggested that such molecular species, if present, must display immunological tissue-specificity, and an immunological approach to describe tissue-differentiation in embryogenesis at the molecul...
One hundred and eighty five consecutive liver biopsies were immunostained using anti-alpha-1-antitrypsin to assess the use of routine immunohistochemistry in the diagnosis of alpha-1-antitrypsin (AAT) deficiency. About half the livers showed staining of hepatocytes for alpha-1-antitrypsin, but most of these livers showed a panlobular pattern, possibly indicating increased synthesis of AAT. Only...
An immunohistological study of four men whose perianal warts were undergoing spontaneous regression was undertaken, and the results compared with those obtained from non-regressing condylomata from six men. CD4+ and CD8+ cells were noted in the stroma of each wart, but there was no clear difference in the density of the infiltrate between regressing and non-regressing warts. Natural killer cell...
In this report we investigated local regulatory mechanisms in graft rejection and their response to local immunosuppressive therapy. For this purpose local immunosuppression was induced in rat kidney allografts by intrarenal infusion of prednisolone. Intrarenal drug delivery resulted in high drug levels within the graft and low systemic drug levels. Systemic drug levels were by themselves not s...
This study was performed in order to characterize the types of the infiltrating cells, and the expression profiles of major histocompatibility complex (MHC) class I and membrane attack complex (MAC) in patients with inflammatory myopathies and dysferlinopathy. Immunohistochemical stains were performed using monoclonal antibodies against several inflammatory cell types, MHC class I, and MAC in m...
