(1) Autopsy finally revealed the adenoid cystic carcinoma of the right lung with bilateral renal metastases.
(2) Enlargement of the jugulodigastric node is most often associated with tonsillitis, and the spinal accessory group of nodes with adenoiditis.
(3) An autopsy case of a 62-year-old woman with a poorly differentiated, aggressive form of adenoid squamous cell carcinoma arising in the skin overlying the right breast was studied.
(4) Postoperative radiotherapy appeared to be effective in obviating local recurrence in patients with adenoid cystic carcinoma of the trachea.
(5) However, the responses of adenoidal and tonsillar lymphocytes to Staphylococcus aureus Cowan strain A were not potentiated by retinoids.
(6) Despite the small number of subjects, the facial morphology of the CF children showed a similar pattern to that of children with nasal respiratory obstruction due to enlarged adenoids or tonsils.
(7) All three studies showed that the effect of adenoidectomy was independent of adenoid size.
(8) All of the lymphoid tissues investigated (bone marrow, thymus, lymph node, spleen, tonsil, adenoid) synthesize complement components in different patterns.
(9) Adenoid cystic carcinoma (ACC) is frequently seen in the salivary glands, but may occur at other sites in the head and neck.
(10) Our results clearly demonstrate that pernasal swabs give a representative picture of the adenoid bacterial content.
(11) IL 1-induced HA release was also observed in preparations of human adenoidal mast cells.
(12) Notably, the tubuloglandular components in 17 (81%) of 21 pleomorphic adenomas were reactive, but no example of either adenoid cystic carcinoma or polymorphous low-grade adenocarcinoma were labeled.
(13) We suggest that staining for fibronectin and laminin may be a valuable aid to the diagnosis of adenoid cystic carcinomas and that the absence of these proteins may have important prognostic implications.
(14) No relapse was observed in ten patients with colloid and one patient with adenoid cystic carcinoma.
(15) Others, in order of descending frequency, had endometrioid, clear cell, colloid, and adenoid cystic carcinomas.
(16) Recurrence in three of six bronchotomies--two with adenoid cystic carcinomata (cylindromata)--necessitated further surgery.
(17) Diagnosis was mainly by histology and was based on the finding of a co-existing pleomorphic adenoma and an authentic adenoid cystic carcinoma, not to be confused with the benign pseudo-cylindromatous appearance sometimes detected in simple pleomorphic adenomas.
(18) Twenty of 41 survivors of resection of squamous cell carcinoma are living free of disease (some for more than 25 years), 39 of 52 with adenoid cystic carcinoma (up to nearly 19 years), and 35 of 42 with other lesions (5 lost to follow-up).
(19) A case of adenoid cystic carcinoma of the oesophagus occurring in a patient who had previously been treated for craniopharyngioma is presented.
(20) Most of the tumors were malignant (56 per cent), with adenoid cystic carcinoma predominating, but the histologic type most frequently encountered was benign mixed tumor (43 per cent).
(1) When chimeric animals were subjected to a lethal challenge of endotoxin, their response was markedly altered by the transferred lymphoid cells.
(2) Histiocytes, lymphocytes, immunoblasts, and plasma cells were present in expanded paracortical regions which encroached on, and occasionally effaced, lymphoid follicles.
(3) The lineage and clonality of Hodgkin's disease (HD) were investigated by analyzing the organization of the immunoglobulin and T-cell receptor beta-chain (T beta) gene loci in 18 cases of HD, and for comparison, in a panel of 103 cases of B- and T-cell non-Hodgkin's lymphomas (NHLs) and lymphoid leukemias (LLs).
(4) The presence of these markers has facilitated the identification and characterization of the mononuclear cells in a number of animal and human lymphoid malignancies.
(5) A constellation of histologic lesions was identified in brain (diffuse meningoencephalitis with bilaterally symmetrical thalamic necrosis), liver (pericholangiohepatitis), lung (pneumonitis), and spleen (lymphoid hyperplasia); this tetrad is apparently unique to this model system.
(6) It was recently demonstrated that MRL-lpr lymphoid cells transferred into lethally irradiated MRL- +mice unexpectedly failed to induce the early onset of lupus syndrome and massive lymphadenopathy of the donor, instead they caused a severe wasting syndrome resembling graft-vs-host (GvH) disease.
(7) Elevated, but variable levels of this protein were observed in proliferating normal fibroblasts and transformed cells of fibroblast, epithelial and lymphoid origin.
(8) Furthermore, these data support our previous suggestion that the expression of human lymphoid differentiation antigens in human-mouse lymphoid hybrids is influenced by the differentiation stage of the fusion partners.
(9) The presence of a previously unreported dipeptide transport mechanism within blood leukocytes and the selective enrichment of the granule enzyme, DPPI, within cytotoxic effector cells of lymphoid or myeloid lineage appear to afford a unique mechanism for the targeting of immunotherapeutic reagents composed of simple dipeptide esters or amides.
(10) Four cases of benign lymphoid hyperplasia (BLH) of the duodenal bulb are reported.
(11) The incomplete penetrance of the neoplastic phenotype and the monoclonality of lymphoid tumors suggest that tumor formation in v-fps mice requires genetic or epigenetic events in addition to expression of the P130gag-fps protein-tyrosine kinase.
(12) These studies demonstrate the potential of ICAM-1 transfectants as tools for analysis of the role of ICAM-1 in lymphoid adhesion.
(13) Between January 1979 and April 1983, 113 children undergoing their first relapse of acute lymphoid leukemia (ALL) at any site were registered in Pediatric Oncology Group study 7834; 98 were eligible and evaluable.
(14) These cells are termed K cells, and although some evidence seems to suggest that they comprise a subpopulation of B lymphocytes, their nature and localization in lymphoid organ is not well known.
(15) Utilization of the immunoglobulin system is based upon the supposition that in lymphoid neoplasms with clonal origin either all or none of the tumor cells should have surface-associated IgM and kappa-reactivities.
(16) These killer cells could lyse a wide range of syngeneic and allogeneic lymphoid tumour cell lines in vitro, and it was found that cell suspensions from nude mice were always significantly more active than those from normal mice, and that the most active effector population was a polymorph-enriched peritoneal-exudate cell suspension.
(17) The expression of p53 was demonstrated in non-T non-B cells and Burkitt's lymphoma cell lines, but neither in two myeloid leukemia cell lines nor in normal lymphoid cells after mitogenic stimulation.
(18) Cyclosporine prevented lymphoid as well as macrophage infiltration of the transplant.
(19) The translocation t(4;11)(q21;q23) is considered a chromosomal marker of acute lymphoid leukemia.
(20) The protein was abundant in all t(14;18)-carrying cell lines and lymphomas and was also found at lower levels in pre-B-cell lines and nonmalignant lymphoid tissues that do not carry t(14;18) translocations.
