antibodies to yersinia enterocolitica in thyroid disease.the prevalence of elevated antibody titers against yersinia enterocolitica was studied in normal subjects, patients with a variety of nonthyroidal illnesses, and patients with thyroid disease. in contrast to the low prevalence of antibodies in controls (less than 8%), 48 of 67 patients (75%) with a variety of thyroid disorders had titers greater than 1:8. antibodies were found in 24 of 36 patients with graves' disease, five of six with autonomous adenoma, seven of seven with hashimoto's thyroidi ...19761036668
[drug sensitivity of yersinia enterocolitica and yersinia pseudotuberculosis].drug-sensitivity of 70 strains of y. enterocolitica and 24 of y. pseudotuberculosis including reference strains and isolates from men or animals were determined by the agar plate-dilution method. all the strains of y. enterocolitica were relatively resistant to penicillins and cephalosporins, while all of y. pseudotuberculosis were sensitive to both of the agents. most of the strains of both species excluding 13 resistant ones were sensitive to streptomycin. the resistant strains, however, were ...19761047115
yersinia enterocolitica septicemia with septic arthritis.we report a case of yersinia enterocolitica septicemia with septic arthritis. gentamicin administration controlled the septicemia but failed to eradicate the organisms in the joint, in spite of a synovial fluid level four times its minimal inhibitory concentration after four days of therapy. development of azotemia necessitated change of antibiotic therapy to chloramphenicol, which eradicated the infection. while y enterocolitica infection in the united states is uncommon, it must be added to th ...1976984993
[experimental infection of axenic mice by "yersinia enterocolitica" (author's transl)].although most of yersinia enterocolitica strains isolated from man have no pathogenicity for laboratory animals, it has been demonstrated that some strains are pathogenic for conventional mice and that most of the strains are probably pathogenic for nude mice. the authors report the results of the infection of germ-free mice with a strain of y. enterocolitica which is non pathogenic for holoxenic mice. it appears that c3h/he mice are sensitive to the infection by gavage or aerogenic and peritone ...1976970831
[influence of substances that change the serotonin level of the brain on the analgesic effect of promedol in rats].in tests with determination of pain reaction in rats registered by their squeak and arising in reponse to a single electric irritation of the tail evidence was obtained to the effect that substances both lowering the serotonin content in the brain (p-chlorphenylalanine, reserpine) and raising it (5-oxytryptophan, pargilin) cause a fall of the threshold, viz. 5-oxytryptophan and pargilin display antagonism to the analgetic effect of trimeperidine hydrochloride, whereas p-chlorphenylalanine, and i ...19761082823
treatment of spontaneous leukemia in akr mice with chemotherapy, immunotherapy, or interferon.akr mice are genetically destined to develop gross (rna) virus-induced lymphatic leukemia. leukemic akr mice treated with combination vincristine, cyclophosphamide (cytoxan), and 1-(2-chloroethyl)-3-(trans-4-methylcyclohexyl)-1-nitrosourea sustained a 180% increase of life-span. combination chemotherapy plus immunization with neuraminidase-treated allogeneic (gross virus-induced) g2g leukemic cells intradermally resulted in 35% of animals surviving beyond 150 days without evidence of the disease ...19761082796

effect of epinephrine on the oxidative desaturation of fatty acids in the rat.the effect of epinephrine on the oxidative desaturation of fatty acids by liver microsomal preparations of rats has been studied. administration of epinephrine (1 mg/kg body weight) produced a significant decrease in desaturation of [l-14c]=linoleic acid to gamma-linolenic acid and of [l-14c]alpha-linolenic acid to actadeca-6,9,12,15-tetraenoic acid 12 hr after the infection. lower doses produced a lesser effect on the delta6-desaturation activity. epinephrine administration modified the v max o ...1976186549
carcinogenic activity of quinoline on rat liver.the effects of prolonged p.o. administration of quinoline or 2-chloroquinoline on rat liver were examined histologically. hepatocellular carcinomas and hemangioendotheliomas were observed in the livers of rats fed a basal diet containing 0.05, 0.10, or 0.25% quinoline for about 16 to 40 weeks. however, no neoplastic changes were seen in the livers of rats fed a basal diet containing 0.05, 0.10, or 0.25% 2-chloroquinoline for 40 weeks. in groups that received low concentrations of quinoline, the ...1976177193
steroid-binding proteins in carcinoma of the human male breast.receptor sites for a group of four steroid hormones were estimated by competitive binding assay of a biopsy specimen of carcinoma from a male breast. the results indicate that the tissue contained a significant number of binding sites for 17beta estradiol, and probably for dihydrotestosterone and progesterone, but not for testosterone. these preliminary data suggest that, as in the female, certain mammary carcinomas in the male may be under the influence of steroid hormones. correlation of such ...1976176884
uridine--cytidine kinase from foetal and adult rat liver. purification and study of some properties.partial purification of uridine--cytidine kinase (ec 2.7.1.48) from foetal rat liver by chromatography on deae-cellulose gives two active fractions. the first in order of elution was identified as a form specific for foetal liver. it was purified 300-fold. the second fraction was common to foetal, and adult rat liver and spleen and was purified 20-fold. the foetal fraction of the enzyme was found to be heat-sensitive and protected against inactivation by po34- anions. the two isolated forms have ...1976186262
transfer of parental immunity to infectious laryngotracheitis in chicks.the transfer of parental immunity to infectious laryngotracheitis was appraised by measuring serum antibody levels in 150 chicks from the day of hatch up to five weeks. the breeder flock which had received primary vaccination at eight weeks and a booster at 20 weeks transferred high antibody levels which fell markedly within two weeks and remained constant thereafter. chicks whose parents were vaccinated at 20 weeks only, had low antibody levels throughout. these low levels, in either group of c ...1976187298

the application of rapid kinetic techniques to the transport of thymidine and 3-o-methylglucose into mammalian cells in suspension culture.techniques are described by which the transport of nutrients into mammalian cells in suspension can be measured at intervals of 1.5 seconds. by application of these techniques, the existence of a saturable (km = 85 mum), non-concentrative, transport system for thymidine was demonstrated in novikoff rat hepatoma cells depleted of atp. at concentrations of thymidine less than the km, this system operated at velocities sufficient to nearly completely equilibrate intra- and extra-cellular thymidine ...1976188833
regulation of carbohydrate permeases and adenylate cyclase in escherichia coli. studies with mutant strains in which enzyme i of the phosphoenolpyruvate:sugar phosphotransferase system is thermolabile.carbohydrate uptake and cyclic adenosine 3':5'-monophosphate (cyclic amp) synthesis were studied employing mutant strains of escherichia coli in which enzyme i of the phosphoenolpyruvate:sugar phosphotransferase system was heat-labile. partial loss of enzyme i activity, which resulted from incubation of cells at the nonpermissive temperature, depressed the rate and extent of methyl alpha-glucoside uptake. temperature inactivation of enzyme i also rendered cyclic amp synthesis and the uptake of s ...1976184083
cell coat in tumor cells -- effects of trypsin and edta: a biochemical and morphological study.the effects of trypsin and edta on the cell coat of ascites tumor cells were studied by means of biochemical and electron microscopy techniques. edta seems to release, by chelation of the ca2+-bridges, an outer layer of glycoproteins of presumably exogenous origin. on the contrary, trypsin produces a deeper enzymic cleavage which appears to affect the structural integrity of the bilayered cell membrane. the significance of the cell leakage in tumor cells and the effect of edta on the modificatio ...1976185564
ultrastructure of lipopolysaccharides of yersinia enterocolitica, salmonella typhimurium and escherichia coli.the fine structure of isolated lipopolysaccharides (lps) from the rough and smooth form of an yersinia enterocolitica strain (ye 75 r/ye 75 s) and from smooth forms of salmonella typhimurium (s 1010) and escherichia coli (essen) were examined electron-microscopically by negative staining. partial denaturation of lps in tris-buffer with acid and/or polymyxin b treatment revealed a common structure of strandlike lps. electron-microscopically, lps-strands were found to consist of two identical sub- ...1976185850
effect of cerebral injury on cerebrospinal fluid cyclic amp concentration.cerbrospinal fluid (csf) cyclic adenosine-3', 5'-monophosphate (camp) was measured in rabbits after experimental brain injury as well as in patients with cerebral contusion and cerebral concussion. in rabbits a marked elevation lasting for two weeks was observed. from the third week onwards after the injury the csf camp concentration was lower than the basal level before the injury. dexamethasone partly inhibited the elevation. ethanol treatment decreased the csf camp values. in man, the csf cam ...1976186266
[changes in the level of acth in the fetal hypophysis. a study in the rat toward the end of gestation].the isolated adrenal cell method for bioassay of acth was employed in order to determine the acth content of the hypophysis of the rat foetus, in late pregnancy. the acth concentration decreases between 17 days 8 h and 17 days 15 h, then it increases regularly until the term. this evolution is correlated with the change in the fluorescence intensity of the corticotrophs and with the modification of the adrenocortical activity.1976177226
the role of serum nonsuppressible insulin-like activity (nsila) in compensatory renal growth.the nonsuppressible insulin-like activity (nsila) of serum is defined as the insulin-like activity measured in insulin bioassays that is not suppressed by addition of insulin antiserum. the major part of serum nsila is attributable to a 90,000 mol wt trace protein which has been recently purified. this study was designed to evaluate the role of serum nsila in compensatory renal growth (crg).1976177337
coxsackievirus and adenovirus infection. association with acute febrile and juvenile rheumatoid arthritis.the prearthritic manifestations of juvenile rheumatoid arthritis in a 16-year-old boy were associated with a rise in coxsackievirus b3 and a9 neutralizing antibody titers from 1:16 to larger than or equal to 1:512, and 1:64 to 1:512, respectively. recurrent polyarthritis followed and has persisted for three years. adenovirus 7 was isolated from the pericardial fluid of a 9-year-old girl in whom juvenile rheumatoid arthritis then developed. of 11 patients with acute, nonspecific, febrile arthriti ...1976177792

investigations on the turnover of adrenocortical mitochondria. iv. a stereological study of the effect of chronic treatment with acth on the size and number of rat zona reticularis mitochondria.the effects of chronic administration of of acth (up to 36 consecutive days) on the mitochondria of the zona reticularis of the rat adrenal cortex were investigated by stereologic techniques. it was found that acth induces two phases of hypertrophy of mitochondria alternating with two proliferative stages, which are associated with a significant decrease in the average volume of the organelles. it is suggested that, as in the zona fasciculata, acth controls the processes of growth and division o ...1976178447
generation of superoxide anion and chemiluminescence by human monocytes during phagocytosis and on contact with surface-bound immunoglobulin g.extent of o-2-release and chemiluminescence, attributed to singlet oxygen, has been compared in human monocytes and neutrophils during phagocytosis, stimulation by the surface-active agent phorbol myristate acetate, or contact with aggregated igg in a model of immune complex disease. monocytes generated o-2-and chemiluminescence with each of the three stimuli, although values were significantly less than those of neutrophils from the same individuals. lymphocytes had no significant activity in e ...1976178824
nad+-malic enzyme. regulatory properties of the enzyme from ascaris suum.the regulatory properties of the nad-dependent malic enzyme from the mitochondria of ascaris suum have been studied. the malate saturation curve exhibits sigmoidicity and the degree of this sigmoidicity increases as the ph is increased. fumarate was the only compound tested that stimulated the enzyme activity, whereas oxalacetate was the most powerful inhibitor. activation by low levels of fumarate was found to be competitive with malate. it is proposed that this stimulation has physiological si ...1976180002
herpes simplex virus specified deoxypyrimidine kinase and the uptake of exogenous nucleosides by infected cells.herpes simplex virus can confer to thymidine kinaseless cells the ability to incorporate exogenously supplied thymidine into acid precipitable material. however no incorporation of exogenously supplied deoxycytidine into acid precipitable material can be detected after infection of deoxycytidine kinaseless cells by herpes simplex virus. this failure to incorporate exogenous deoxycytidine is not due to the failure of the deoxycytidine phosphorylating activity of the virus induced deoxycytidine ki ...1976180246
serum testosterone and dihydrotestosterone in patients with trophoblastic disease.serum testosterone (t) and dihydrotestosterone (dht) were measured by radioimmunoassay in 14 patients with unaborted hydatidiform mole and in 16 patients with normal pregnancy of similar gestational age. serum human chorionic gonadotropin (hcg) was measured by the radioreceptor assay in patients with hydatidiform mole. serum t ranged from 0.27 to 5.39 ng/ml with a mean +/- se of 2.21 +/- 0.45 ng/ml in patients with hydatidiform mole mole and from 0.20 to 2.40 ng/ml with a mean +/- se of 0.80 +/- ...1976180465
regulation of pyruvate dehydrogenase in rat heart. mechanism of regulation of proportions of dephosphorylated and phosphorylated enzyme by oxidation of fatty acids and ketone bodies and of effects of diabetes: role of coenzyme a, acetyl-coenzyme a and reduced and oxidized nicotinamide-adenine dinucleotide.the proportion of active (dephosphorylated) pyruvate dehydrogenase in perfused rat heart was decreased by alloxan-diabetes or by perfusion with media containing acetate, n-octanoate or palmitate. the total activity of the dehydrogenase was unchanged. 2. pyruvate (5 or 25mm) or dichloroacetate (1mm) increased the proportion of active (dephosphorylated) pyruvate dehydrogenase in perfused rat heart, presumably by inhibiting the pyruvate dehydrogenase kinase reaction. alloxan-diabetes markedly decre ...1976180974

(preliminary communication) (author's transl)].after a brief description of the micro-biological, pathological, anatomical and clinical picture of infections with yersinia enteroclitica, attention is drawn to the striking radiological similarity between three patients with yersinia infection and regional enteritis (crohn's disease). whilst the radiological findings due to yersinia infection usually resemble the group of so-called non-sclerosing ileitis (golden) they occasionally differ from this group and resemble the findings in crohn's dis ...1976137848
differentiaton of neuropharmacological actions of apomorphine and d-amphetamine.the dopaminergic agonists apomorphine and d-amphetamine elicit hyperthermic, hyperkinetic and stereotypic responses in the rabbit. the present investigation compares the influence exerted by various serotonergic antagonists upon these activities. apomorphine-induced hyperthemia was antagonized by p-chlorophenylalanine (pcpa), cyproheptadine and cinanserin and was restored in pcpa-pretreated rabbits by regeneration of central serotonin levels, d-amphetamine-induced hyperthermia was reduced by pcp ...1976139615
binding of cibacron blue f3ga to proteins containing the dinucleotide fold.a simple, convenient, and sensitive spectrophotometric procedure is described for quantitative measurement of nucleoside phosphate binding sites constructed by the dinucleotide fold. the procedure involves difference spectral titration of such enzymes with the dye cibacron blue f3ga in a spectral region remote from the intrinsic absorbance of proteins or natural ligands. the titration curves can be analyzed to determine the affinity of nucleoside phosphate binding sites for both the dye and the ...1976174104
ischemia-induced alterations in myocardial (na+ + k+)-atpase and cardiac glycoside binding.the effects of ischemia on the canine myocardial (na+ + k+)-atpase complex were examined in terms of alterations in cardiac glycoside binding and enzymatic activity. ability of the myocardial cell to bind tritiated ouabain in vivo was assessed after 1, 2, and 6 h of coronary occlusion followed by 45 min of reperfusion, and correlated with measurements of in vitro (na+ + k+)-atpase activity and in vitro [3h]ouabain binding after similar periods of ischemia. regional blood flow alterations during ...1976130383
[spontaneous peripheral proteolysis/1st communication: method and results of clinical examinations (author's transl)].with a modificated astrup-fibrin plate-method also an inhibition of proteolysis can be registrated. in various medical areas a spontaneous peripheral proteolysis had been found, especially so in chronical bacterial infections.1976132940
the effect of increased brain gaba produced by amino-oxyacetic acid on arousal in rats.previous work has reported behavioral arousal in the rat to be inversely related to cortical gaba production. therefore the effects of an increase in brain gaba levels, induced by amino-oxyacetic acid, on measures of behavioural arousal such as rearing and ambulation were examined. the increase in gaba was immediately associated with decreased rearing, however the behaviour was later indistinguishable from control values while the levels of brain gaba remained raised. it was suggested that the r ...1976134388
allergic reaction to allopurinol with cross-reactivity to oxypurinol.a 25-year-old white man with gout and nephropathy and with a previous reaction to allopurinol was given a trial dose of oxypurinol. he developed malaise, a generalized erythematous reaction with edema, pruritus, and emesis; this was clinically identical to the reaction he experienced with allopurinol. when the patient's lymphocytes were exposed in vitro to oxypurinol and allopurinol, increased dna synthesis was observed, suggesting an immunologic basis for the reaction. this patient indicates th ...1976134655
[study of the threshold dose of penicillin which induces an epileptogenic focus during ontogenesis in the rabbit].a local application on the cortex surface of a very small drop of ringer solution containing penicillin was performed to establish the threshold dose required to elicit and epileptogenic focus and consequently the occuring latency of it. threshold doses are small (20 - 60 international units) and show a significant decrease during the maturation of the c.n.s. on the other hand latencies, whatever the animal's age, decrease fairly. the results are confronted to the various supposed modes of actio ...1976134784
[antigenic analysis and immunological studies of the uterotropic bacterial strains sh6 and 01 isolated from aborted cows].the uterotropic strains sh6 and o1 were studied immunoelectrophoretically to establish their antigenic relationship. the more readily diffusing component of the o-antigenic fraction of the strains proved immunologically identical with lpa of the r brucella organisms, while the slower component showed common determinants with the o-antigenic fraction of yersinia pseudotuberculosis. immunodiffusion revealed that the o-antigenic fraction of the o1 strain and lpa of the s brucella organisms contain ...197660821

a serial study of pregnancy proteins in primigravidae.the plasma concentrations from four 'pregnancy proteins' and three steroid hormones have been measured throughout pregnancy in 15 primigravidae. two of the proteins, human placental lactogen (hpl) and pregnancy-specific beta1-glycoprotein (psbetag), are specific for pregnancy and correlate well with the stage of gestation. it is suggested that measurement of psbetag may be useful in assessing feto-placental wellbeing. neither of the pregnancy-associated proteins, steriod-binding beta-globulin (s ...197657799
antigenic relationship between morganella morganii and yersinia enterocolitica.two new o antigens have been described for the morganella morganii antigenic schema. o antigens of the strains representing the new serotypes (o43 :h2 and o44 : h19, 37) are related to yersinia enterocolitica o9 and o17, respectively.197659520
