Aqueous extracts of acetone/ether powders of surgically obtained specimens of human tumors hydrolyzed 3H-labeled triolein in a dose-dependent manner. The lipolytic activity in these extracts was inhibited by anti-lipoprotein lipase (LPL) IgG dose-dependently, 25 micrograms of anti-LPL IgG causing
The authors studied 11 cases of Kaposi's sarcoma (KS) in patients with the acquired immunodeficiency syndrome (AIDS) for their reactivity with two monoclonal antibodies (B721 and E431) that recognize endothelial cell surface antigens. Reactivity of these antibodies with KS was compared with the
The purpose of this study was to explore the triacylglycerol (TG) deposition and lipoprotein lipase (LPL) activity in the adipose tissue of patients with muculoskeletal sarcoma. Subcutaneous adipose tissue was obtained from the thighs of 19 patients with musculoskeletal sarcomas (sarcoma group) and
1. The total lipid was extracted from BP8/C3H ascites-sarcoma cells with acetone, light petroleum, pyridine and chloroform-methanol successively. Each extract was treated with mild alkali. The alkali-stable lipids from the pyridine and chloroform-methanol extracts, which included the glycolipids,
The many different theories on the histogenesis of alveolar soft part sarcoma (ASPS) have caused great confusion. Owing to the recent rapid advance in immunohistochemical studies, two major hypotheses have been proposed. One group of researchers supports the idea that ASPS shows myogenic
We report a 2-year-old Japanese boy without bone marrow involvement who developed a primary granulocytic sarcoma in his spinal canal. Tumour cells were positive for myeloperoxidase, MIC2, CD56 and, CD68 on formalin-fixed, paraffin-embedded tissue sections and CD13, CD33, CD45, and CD64 on
Succinic dehydrogenase (SDH) was localized in the mitochondria of Sarcoma 37 ascites tumor cells by the use of tetranitro-BT (TNBT) and nitro-BT (NBT) in smear preparations. Results with each tetrazolium salt as electron acceptor were evaluated with respect to: (a) size and shape of the formazan
BACKGROUND
Cytologic diagnosis of canine histiocytic sarcoma (CHS) can be challenging because neoplastic histiocytes commonly show marked nuclear and cellular atypia and may resemble other pleomorphic malignant round cell tumors. Therefore, even on histopathologic examination, immunostaining is
The localization of the avian sarcoma virus src gene product (termed p60src) was examined by indirect immunofluorescence in cells transformed by the Schmidt-Ruppin strain of Rous sarcoma virus, subgroup D (SR-RSV-D). Antiserum to p60src was obtained from rabbits bearing SR-RSV-D-induced tumors, and
Antimalarial drugs, dihydroartemisinin (DHA) and artesunate (ATS), exhibit iron-dependent cytotoxicity in tumor cells. We hypothesized that erythrophagocytic uptake of heme-iron enhances the cytotoxicity of DHA and ATS. Erythrophagocytic (EP) treatment of the canine histiocytic sarcoma cell line
A tumor antigen associated wtih canine transmissible venereal sarcoma (CTVS) has been identified and partially characterized. The antigen was demonstrated in 3-M KCI and saline extracts of washed CTVS cells. Rabbit anti-CTVS antisera absorbed wih glutaraldehyde cross-linked normal dog serum and
The presence of individual keratin polypeptides and desmoplakins was immunohistochemically studied in 25 spindle cell sarcomas of different types using acetone-fixed frozen sections. Results revealed that keratins 8 and 18 were present in a high number of tumors: 9 of 9 synovial sarcomas, 5 of 7
Two cases of true histiocytic lymphoma of the small intestine occurred in middle-aged patients, manifesting as tumors causing intestinal obstruction. One of the patients died of uncontrollable local and metastatic disease, 16 months after surgery and polychemotherapy, and the other patient is alive
The localization of 169Yb, 67Ga and 111In in tumor tissues was determined macroautoradiographically. 169Yb-citrate and 111In-citrate were injected intravenously to the rats subcutaneously transplanted Yoshida sarcoma and were injected intraperitoneally to the mice subcutaneously transplanted Ehrlich
BACKGROUND
Trimethylolpropane triacrylate (TMPTA) is used as an ingredient in a wide variety of coatings, resins, photosensitive materials, and superabsorbent baby diapers. We studied the effects of TMPTA on male and female rats and mice to identify potential toxic or cancer-related
