the involvement of suppressor t cells in ir gene regulation of secondary antibody responses of primed (responder x nonresponder)f1 mice to macrophage-bound l-glutamic acid60-l-alanine30-l-tyrosine.(responder [r] x nonresponder [nr])f1 mice give indistinguishable primary in vitro plaque-forming cell (pfc) responses to either r or nr parental macrophages (mphi) pulsed with the ir-gene controlled antigen l-glutamic acid60-l-alanine30-l-tyrosine10 (gat). however, such (r x nr)f1 mice, if primed to gat, retained in vitro responsiveness to gat-r-mphi, but no longer responded to gat-nr-mphi. this suggested (a) a possible mphi-related locus for ir gene activity in this model, and (b) the occurren ...2000102725
pre-b and b cells in rabbits. ontogeny and allelic exclusion of kappa light chain genes.pre-b cells in developing rabbits were identified by immunofluorescence as cells containing small amounts of cytoplasmic igm (cigm) but lacking surface immunoglobulin (sig). during ontogeny the first pre-b cells appeared in fetal liver at 23 days gestation, 2 days before the appearance of sigm+ b lymphocytes. pre-b cells were relatively frequent in fetal and adult bone marrow, but were not found in other tissues except rarely in fetal spleen. allelic exclusion is apparently established at this e ...1978102726
n,n'-(phenylene)dioxamic acids and their esters as antiallergy agents.a series of dialkyl n,n'-(m-phenylene)dioxamates was synthesized by treatment of the requisite m-phenylenediamines with an alkyloxalyl chloride in the presence of triethylamine. hydrolysis with sodium hydroxide solution gave the corresponding n,n'-(m-phenylene)dioxamic acids. several n,n'-(p-phenylene)dioxamic acids were synthesized also in the same manner starting with the requisite p-phenylenediamines. these compounds were tested in the rat passive cutaneous anaphylaxis (pca) assay. when teste ...1978102796

studies on acute and late stages of experimental central retinal artery occlusion in the cynomolgus monkey. i. intensity-amplitude relations of the d.c. recorded erg with special reference to the c-wave.the main positive component of the c-wave of the erg is generated by the pigment epithelium-receptor complex, which is supplied from the choroidal circulation. occlusion of the central retinal artery (ocra) causes serious morphological damage only to the inner retina. an effect on the c-wave is therefore not primarily to be expected. in this study on five cynomolgus monkeys with unilateral, laser-induced ocra the c-wave was decreased, slightly in the early stage and markedly in the late stage. a ...1978104542
chondroitin 4- and 6-sulfate mucopolysaccharidosis--a morphological study.a 17-year-old patient clinically manifesting gargoyle face, dwarfism, skeletal bone deformity, mild mental retardation and benign course was presented. biochemically, increased urinary excretion of acidic glycosaminoglycans was confirmed and chondroitin 4-sulfate and chondroitin 6-sulfate were substantiated to be the major components of the acid mucopolysacchariduria. light microscopically, variable numbers of foam cells were observed in the biopsy materials of the lymph nodes, liver and skin, a ...1998104545
delayed hypersensitivity to tuberculin in rats: effects of antirheumatic drugs.the effects of different antirheumatic drugs administered according to various dosing regimes on tuberculin hypersensitivity in rats have been assessed quantitating the changes of exudate volume and mononuclear cells immigration at the site of challenge. dosing at the time of sensitization with aurothiomalate and d-penicillamine enhanced the cell immigration which was decreased by similar treatment with levamisole. cyclophosphamide increased the exudate formation. indomethacin had no effect. dos ...1979104548
intermittent bleeding from minute to minute in acute massive gastrointestinal hemorrhage: arteriographic demonstration.acute massive gastrointestinal hemorrhage can be intermittent from minute to minute. this phenomenon is documented by arteriography in three patients. failure to demonstrate active bleeding by angiography therefore may not prove cessation of bleeding or indicate an inadequate examination.1998104564
intraarticular methyl methacrylate: a complication of hip surgery.methyl methacrylate, used as a grout during hip arthroplasty, can inadvertently become lodged between acetabular and femoral components during surgery. after resumption of ambulation, crescentic fragments may extrude into the pseudocapsule. if mobile methyl methacrylate fragments lodge within the joint, late surgical failure may result because of methyl methacrylate's abrasive character. two cases of total hip replacement and one case of femoral arthroplasty are reported in which intraarticular ...1998104573

purification and characterization of urinary choriogonadotropin from patients with hydatidiform mole.human choriogonadotropin was isolated from urine of patients with hydatidiform mole by acid and salt precipitation, immunoaffinity, and deae-sephadex chromatography. polyacrylamide gel electrophoresis, immunodiffusion, immunoelectrophoresis, and nh2-terminal amino acid analysis showed that the product obtained is essentially homogeneous. this choriogonadotropin was found to resemble the choriogonadotropin from urine of normal pregnant women in amino acid composition but to differ from it in havi ...1979105001
bullous pemphigoid antigen. ii. isolation from the urine of a patient.this report concerns the isolation of bullous pemphigoid antigen from the nondialyzable urinary components of a patient with the disease. the isolation was accomplished by ion exchange chromatography and gel filtration. pemphigoid antigen was found to be a basic glycoprotein that on sds gel electrophoresis showed two major bands, one in the 18,000 m. w. region and the second with a m. w. of 74,000. between these two bands, two additional bands appeared; one of 35,000 daltons and the other of 68, ...1979105049
double-blind study of levamisole in aphthous stomatitis.sixty-five patients with recurrent aphthous stomatitis participated in a double-blind study to evaluate levamisole. nineteen of 34 patients improved on levamisole and only five of 31 patients improved on placebo (p less than 0.004, chi-square with two degrees of freedom). after breaking the code and switching placebo patients to levamisole and non-responders to an alternate dosage schedule, 46 of 60 patients noted clinical improvement.1998105099
immunological aspects of recurrent oral ulceration and behçet's syndrome.immunological factors play in recurrent oral ulceration (rou) and behçet's syndrome (bs) but these cannot be distinguished by means of antibodies and cell-mediated immune responses to oral mucosal antigens. however, hla markers seem to differentiate rou from bs. immune complexes have now been found in about 55% of patients with bs and fewer patients with rou, so that the transition from the focal rou to the multifocal bs might be mediated by immune complexes. immunopathological studies have show ...1998105103
