primary structure of a human iga1 immunoglobulin. iv. streptococcal iga1 protease, digestion, fab and fc fragments, and the complete amino acid sequence of the alpha 1 heavy chain. | in order to establish the complete amino acid sequence of the human iga alpha1 chain bur, iga1 protease from streptococcus sanguis was employed to generate fabalpha and fcalpha fragments in the final stage of this investigation. cyanogen bromide cleavage of the fabalpha fragment followed by reduction and aminoethylation produced the fd' fragment (residues 84 to 227); this contains part of the variable region (vr), the whole first constant domain (calpha1), and part of the hinge region of this he ... | 1979 | 107164 |
[validity of scintigraphic and endocrinological methods in classifying autonomous adenomas of the thyroid (author's transl)]. | the validity of various scintigraphic and endocrinological methods was assessed in order to classify confirmed autonomous adenomas (aa) and to differentiate aa from euthyroid and hyperthyroid goitres. methods used included: measurement of 131j-uptake 6, 24 and 48 hours after 131j-application, before and after suppression by t3, thyroid scanning, count-rate measurement in the aa and the paranodular tissue, and determination of t4. all patients received 131j-therapy (40,000 rads). in 8 out of 30 s ... | 1979 | 107394 |
similarity of casein- and endotoxin-induced, myeloma- associated and aged sjl/j amyloid in various strains of mice. | amyloidosis was induced in a number of strains of mice by repeated injections of casein and endotoxin. spontaneous amyloid was obtained from balb/c mice bearing a myeloma tumor (igg2a producing mopc 173 tumor) and from aged sjl/j mice. both the induced and spontaneous forms were similar in their size, immunological reactivity, peptide maps and in the susceptibility of histological sections to oxidizing agents with or without trypsin digestion. since case-induced murine amyloid resembles the noni ... | 1979 | 87374 |
oncofetal antigen: a tumor-associated fetal antigen immunogenic in man. | oncofetal antigen (ofa) has been defined with the use of human natural antibodies as a membrane antigen of human cancer cells that cross-reacts with human fetal brain tissues. the immunogen that elicits the antibody is unknown. the present study was undertaken to examine the immunogenicity of the ofa found on tumor cells. postoperative melanoma patients were immunized with ofa-positive melanoma cells. anti-ofa reactivities in the immunized sera were titrated by the immune adherence assay with th ... | 1979 | 88539 |
experimental studies of the pathogenesis of infections due to pseudomonas aeruginosa: extracellular protease and elastase as in vivo virulence factors. | the effects on mortality of supplemental injections of protease and elastase were determined in burned mice infected with non-lethal inocula of a toxin-producing but non-proteolytic-enzyme-producing strain of pseudomonas aeruginosa. when a variety of solutions containing proteolytic enzyme were injected under these conditions, the mortality increased significantly. this did not occur when organisms other than p. aeruginosa were used. injections of the enzyme solutions alone were non-lethal. inje ... | 1979 | 89891 |

ia determinants on human t-cell subsets defined by monoclonal antibody. activation stimuli required for expression. | the nature of ia antigens which appear on human t cells after activation and the stimuli required for their expression was examined utilizing a monoclonal antibody reactive with the ia antigen framework. t cells were purified using monoclonal antibodies directed either at the entire t-cell population (okt3) or the t-cell inducer subset (okt4). by indirect immunofluorescence, it was shown that the human t-cell population contains no detectable ia+ cells in the resting state. in contrast, in exces ... | 1979 | 92523 |
ionomycin stimulates mast cell histamine secretion by forming a lipid-soluble calcium complex. | the activation of cellular function following the direct introduction of ca2+ into the cytosol by the use of a ca2+-transporting ionophore has served to confirm the widely held idea that ca2+ has the status of a second messenger in many cell types. however, this evidence has been obtained largely from the use of a single ionophore, the antibiotic a23187; experiments with x537a, which is another ionophorous antibiotic capable of transporting ca2+ (ref. 3), have failed to show the expected charact ... | 1979 | 92764 |
differences in the susceptibility of mhc and non-mhc mixed lymphocyte reactions to suppression by murine amnionic fluid and its components. | the ability of mouse amniotic fluid (maf), alpha-foetoprotein (afp) and maf depleted of afp (maf - afp) to suppress primary one-way mlr's was investigated. it was found that maf, afp and maf - afp were all suppressive of mlr's specific for mhc, k, d or i + s determinants. suppression was observed when either lymph node or spleen cells were used as the responder cells. nylon wool column passage of these cells did not significantly affect the immunosuppressive action of these substances. in contra ... | 1979 | 93135 |
[changes in blood levels of noradrenaline in man following short and long term exogenous infusion]. | norepinephrine (ne) was infused in four normal men in doses of 1.5, 6.0 and 9.0 microgram/min for 60 min. the rise in plasma ne was observed only after 5 min and steady state plasma ne and infusion rates. the calculated turnover time averaged 35 sec for 1.5 microgram/min infusion and 20 sec for both 6.0 and 9.0 microgram/min infusion experiments. these differences may be explained by adjustments occurring in inactivation processes in relation to infused doses. a basal endogenous overflow rate of ... | 1979 | 93441 |
spiroplasmas: serological grouping of strains associated with plants and insects. | spiroplasma strains from plant and arthropod hosts, and from surfaces of flowers, were classified into three serological groups (designated i, ii, and iii) based on results from growth-inhibition tests. no significant cross reactions were observed among groups. the groupings were confirmed by ring-interface precipitin and microprecipitin tests, using membrane preparations as test antigens, and by organism-deformation tests. serogroup i contained three subgroups: subgroup a (spiroplasma citri str ... | 1979 | 93504 |

generation of specfic t-cell suppressor function induced by streptococcus mutans in monkeys and mice. | specific suppressor cells in mice and monkeys can be induced with high doses of streptococcus mutans antigen. when these cells are further cultured with a low dose of s. mutans antigen in vitro, they secrete specific suppressor factors which decrease the cooperative responses to this antigen. in view of the sensitivity of these cells to anti-thy 1 and complement, and as they are not retained on nylon-wool, these suppressor cells are t cells. the suppressor factor exerts its effect on t helper ce ... | 1979 | 93576 |
in vivo induction of endogenous retroviruses in balb/c mouse hepatocytes by successive treatments with carbon tetrachloride and bromodeoxyuridine. | the effects of bromodeoxyuridine (brdurd) incorporation into hepatocytes of carbon tetrachloride (ccl4)-induced regenerating liver of balb/c mice on the induction of endogenous retroviruses was examined. from the nucliec acid hybridization studies, the maximum levels of hybridization were obtained for both n- and x-tropic balb/c endogenous retrovirus specific [3h]-cdnas with liver rna from animals receiving brdurd at 40 and 44 h post-ccl4 treatment, and killed on the fourth day following brdurd ... | 1979 | 93580 |

histochemical characteristics of the anal sacs of the cat. | the histochemistry of polysaccharides and proteins and the distribution of rna were investigated in the glands and mature secretion of the anal sacs of the cat. glycogen was extremely abundant in the epithelial lining of the lumen and efferent duct of the anal sac and also in ducts of sebaceous glands of the sacs constantly formed in the place of degenerating acini. little glycogen was found in the unchanged sebaceous acini. the apocrine glands of the anal sacs were substantially richer in glyco ... | 1979 | 95391 |
dynamic inorganic ion-protein interactions in structural organization of dna of living cell nuclei. | staining polarization optical techniques showed differences in the structural organization of dna of chromatin in interphase nuclei and in mitotic chromosomes. the dna was non-birefringent in intact interphase cell nuclei, but birefringent in chromosomes and in isolated nuclei incubated in a physiological electrolyte solution. the birefringence of dna appears to be related to an unfolding of dna filaments induced by free cations and to the oriented binding of dye molecules to dna phosphates. we ... | 1979 | 95394 |
fetal hemoglobin: in vivo stimulation by d-thyroxine in adult marmosets. | reactivation of fetal hemoglobin gene expressions was studied in new-world monkeys (marmosets). after a series of intraperitoneal injections of d-thyroxine, fetal hemoglobin production was increased in three experimental animals. control animals were unaffected by the injection of the solvent. because the percentage of cells containing fetal hemoglobin exceeded the total percentage of fetal hemoglobin, it was concluded that thyroid hormone influenced the synthesis of fetal hemoglobin rather than ... | 1979 | 95517 |
