effects of poly(1-vinyluracil) and poly(9-vinyladenine) on viral rna-directed dna polymerase.the effects of poly(1-vinyluracil) [poly(vu)] and poly(9-vinyladenine) [poly(va)] on the rna-dependent dna polymerase activity of murine leukemia virus (moloney strain) were studied. vinyl polymers themselves cannot act as templates for the polymerase. however, if a vinyl polymer is added to a polymerase reaction mixture in which a complementary polynucleotide serves as the template, the reaction is inhibited: thus with polyribocytidylic acid as template and oligodeoxyguanylic acid as primer, ne ...197656995
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
comparison of chlamydia subgroup a detection from clinical specimens after 40 and 64 hours of incubation in 5-iodo-2-deoxyuridine-treated mccoy's cells.the time course of formation of inclusion bodies produced by chlamydia in 5-iodo-2-deoxyuridine (iudr)-treated mccoy's cells was studied with the use of a known isolate of chlamydia trachomatis d/uw-184/ur and 47 frozen clinical urethral specimens previously shown to be either positive or negative for chlamydial inclusions after 3 days of incubation. subsequent examination of 369 clinical specimens from the genitourinary tract over a 6-month period revealed 47 (13%) chlamydia-positive cultures, ...197657968

evidence for more than one ia antigenic specificity on molecules determined by the i-a subregion of the mouse major histocompatibility complex.ia antigenic specificities determined by the i-a subregion of the mouse major histocompatibility complex have been examined in strain b10.d2 (h-2d), c57bl/10 (h-2b), and in a (c57bl/6xdba/2) hybrid (bdf1; h-2b/d). detergent solubilized, 3h-leucine-labeled antigen preparations were mixed with appropriate alloantisera and precipitation was induced either by addition of goat anti-mouse gamma-globulin or by addition of protein a-bearing staphylococci. sequential precipitation analysis showed that in ...197655444
anatomical organization of the phasic activity produced by reserpine at the level of the oculomotor system.the organization of the pathways responsible for the transmission of phasic electrical activity at the level of the oculomotor system was studied in the encéphale isolé cat which was injected with reserpine or exhibited spontaneous phases of paradoxical sleep. at the level of the vith nuclei there are both ipsilateral and contralateral connections deriving from each generator. the ipsilateral pathway transmits an "inhibiting" potential eliciting electromyographic inhibition of the ipsilateral re ...197655344
some properties of the polysaccharide from cell cultures infected with tric agent (chlamydia trachomatis).the polysaccharide, elaborated in trachoma-inclusion conjunctivitis (tric) agent inclusions, was isolated from baby hamster kidney (bhk) cells grown and infected in suspension cultures. it was characterized by physical, chemical and enzymic methods as a glycogen with an average chain length of 14 to 16 glucose units.197551905
induced metabolic sequelae of tularemia in the rat: correlation with tissue damage.serum and liver zinc concentration, amino acid uptake by liver, seromucoid content, and alpha2-macrofetoprotein production were measured in vaccinated as well as nonimmune rats exposed to either virulent (schu s4) or attenuated (lvs) strains of francisella tularensi. it appears that liver damage (pyogranulomatous lesions) must occur before there is any alteration in the above variables. the presence of bacteria in the liver is not of itself sufficient to lead to the onset of systemic, induced me ...197551592
isoelectric focusing of chlamydia trachomatis.hela-229 cells and the elementary bodies of chlamydia trachomatis had a net negative electrical surface charge at neutral ph when measured by isoelectric focusing. inclusion-forming and non-inclusion-forming elementary bodies focused in one band at pi 4.64.197944706

the stimulatory effect of 5ht and the role of the paraventricular nucleus on pms induced ovulation in the immature rat.immature rats can be induced to ovulate with pregnant mare serum (pms) as long as they weigh over 60 g. in the rats weighing less than 60 g 5-hydroxytryptamine (5ht)-60 micrograms/rat intraventricularly or 2 micrograms/rat in the paraventricular nucleus (pvn)-stimulated ovulation. injections into several other hypothalamic nuclei were ineffective. in rats weighing greater than 60 g, lesions of the pvn or injection of 10 micrograms/rat p-chlorophenylalanine into the pvn inhibited ovulation. the h ...197937456
factors affecting the incidence and anti-salmonella activity of the anaerobic caecal flora of the young chick.thirty-two different types of anaerobic bacteria isolated from chickens have been tested for anti-salmonella activity in vitro. under the conditions of the test only bacteroides hypermegas and a bifidobacterium sp. were shown to inhibit the salmonellas and this was attributed to the production of volatile fatty acids (vfa's) coupled with a low ph. when these organisms were tested in newly hatched chicks no inhibition of s. typhimurium occurred. possible explanations for this observation are cons ...197934658
kinetic studies in isolated organs: tools to design analgesic peptides and to analyze their receptor effects.the opioid activities of peptide and non-peptide narcotics were studied in longitudinal muscle strip of guinea pig ileum (gpi) and in mouse vas deferens (mvd). the comparison of agonist activities of peptides found in gpi and mvd offered the opportunity to predict the presence but not the magnitude of potential analgesic activity. the kinetics of the antagonism between naltrexone and different types of agonists were also determined in these systems. using c-6 epimers of naltrexone, it was found ...197933396

early diagnosis of crepitant gangrene caused by bacteroides melaninogenicus.a rapid non-invasive test for the presence of b. melaninogenicus in the wounds of crepitant non-clostridial gangrene is described. the wounds are viewed under an ultraviolet light, and the presence of bright red fluorescene indicates the probable presence of b. melaninogenicus.197827832
pharmacological study of chicken airway smooth muscle.isolated chicken bronchus contracts to carbachol, pgf2alpha, histamine, 5-ht, bradykinin and phenylephrine. the bronchial strips from the horse plasma sensitized domestic fowl contracted to specific sensitizing antigen in vitro (schultz-dale anaphylactic reaction) and were 5 to 10 fold more reactive to pgf2alpha, histamine and 5-ht compared with the bronchi from normal chickens. second antigen challenge was inactive or produced a weak response (desensitization). allowing the bronchi to rest for ...197827609
diisopropylfluorophosphate-evoked inhibition of anaphylactic histamine release from human skin: decrease of the inhibition by storing the skin specimens.antigen-induced histamine release from human skin slices passively sensitized with reaginic serum in vitro was inhibited by dfp, suggesting involvement of serine esterase activation in the reaction. the magnitude of dfp-evoked inhibition of the histamine release was not the same in each skin sample and no correlationship was observed between the magnitude of the dfp-evoked inhibition of the histamine release and that of the histamine release in the absence of dfp. the magnitude of the histamine ...197984487
the effects of acridine orange on deoxyribonucleic acid in escherichia coli.1. acridine orange inhibits growth of escherichia coli k12 when incubated at ph 7.9, but not at ph 7.4.2. at a non-permissive temperature for dna polymerase i, acridine orange inhibits growth of a temperature-sensitive strain and also increases the rate of elimination of the f'-lac plasmid. 3. dna isolated from cells treated with acridine orange under conditions that inhibit growth contains material of low molecular weight, which is absent from dna isolated from cells treated under conditions in ...197827167

cellular and humoral immunity in viral hepatitis.cellular and humoral immunity combine to determine the outcome following exposure to hepatitis virus and are implicated in the proposed pathogenetic mechanism for acute and chronic hepatitis. although antibody to hbsag is found in virtually all following recovery from hepatitis b, a cell-mediated response to hbsag can be detected in most patients during the acute phase, and it has been suggested that this may cause the acute hepatic damage by an attack on virus-infected cells. patients who have ...197685410
subarachnoid space of the cns, nasal mucosa, and lymphatic system.we have briefly reviewed the literature pertaining to the movement of tracer molecules and infectious organisms within the olfactory nerve. there is a body of evidence indicating that tracers placed in the csf will quickly move via the olfactory nerve to the nasal mucosa and then to the cervical lymph nodes. organic and inorganic tracer materials and organisms as diverse as viruses, a bacillus, and an amoeba, when placed in the nasal cavity, have been shown to move from the nasal mucosa via the ...197985446
evidence for two forms of rna-dependent dna polymerase in visna virus.the visna viral rna-dependent dna polymerase has been resolved into two forms by affinity chromatography. glycerine gradient centrifugation of the two forms showed that one form sedimented at 6.9 s corresponding to an apparent molecular weight of 135 000 and the other at 6.3 s corresponding to 118 000. sodium dodecyl sulfate (sds)-polyacrylamide gel electrophoresis of the two forms indicated that the 6.9 s enzyme is composed of 2 molecules of 68 000 mol. wt. chain and the 6.3 s is a single chain ...197985464
isolation of a nucleocapsid polypeptide of herpes simplex virus types 1 and 2 possessing immunologically type-specific and cross-reactive determinants.a polypeptide (p40) of approximately 40,000 molecular weight was isolated from herpes simplex virus type 1 and 2 nucleocapsids by gel filtration and ion exchange chromatography. this protein appears to be the same as protein 22a described previously (gibson and roizman, j. virol. 10:1044--1052, 1972). competition immunoassays were developed by using purified p40 and antisera prepared in guinea pigs. the assays indicated that the p40's from herpes simplex virus types 1 and 2 possess both type-spe ...197985720

acute bacteremia in asplenic renal transplant patients.four cases of overwhelming bacteremia were observed in asplenic renal transplant patients 12 to 20 months after transplantation. the bacteriologic findings and presentation of these infections are characteristic of post-splenectomy sepsis reported in nontransplant patients. it is suggested that the absence of the spleen, more than immunosuppression with azathioprine and prednisone, predisposes to these late, uncommon infections after transplantation.197716144
hormonal control of zinc uptake and binding in the rat dorsolateral prostate.the zinc uptake in the dorsolateral prostate of rats was studied after different hormonal manipulations. orchiectomy reduced the uptake of 65zn. administration of estradiol benzoate to orchiectomized rats doubled the 65zn uptake, a phenomenon which was not observed in orchiectomized-adrenalectomized rats. adrenalectomy in orchiectomized rats had no effect on the concentration of radioactivity beyond the castration-induced decrease. a prolactin release inhibitor, 6-methyl-8-erogelenylacetamide, r ...197715955
the isolated human cortex. a golgi analysis of krabbe's disease.the clinical course of a child with krabbe's leukodystrophy was characterized by clinical seizures, startle myoclonus, and paroxysmal activity recorded by eeg. at autopsy in the fourth year, myelinated subcortical axons were destroyed, virtually completely. despite isolation from major subcortical and interhemispheric connections, the cell and fiber pattern of the cortex appeared remarkably normal in routine histologic preparations. the normal range of pyramidal and stellate interneurons were al ...197986346
low dose lithium-carbimazole in the treatment of thyrotoxicosis.fifteen patients with thyrotoxicosis were treated with low dose sustained release lithium carbonate 400 mg, combined with carbimazole 40 mg daily, and the therapeutic response was followed over a two week period. this response was compared with that obtained in a similar group of patient treated with carbimazole alone. li-carbimazole treatment brought about a fall in the mean total serum t4 of 57.4% compared with a drop of 32.8% in patients treated with carbimazole alone. the mean serum t3 fell ...197886350
normal immunosuppressive protein inhibition of human and murine lymphoblastoid cell line proliferation.normal immunosuppressive protein, prepared from human plasma by deae-cellulose chromatography, inhibits dna synthesis in human cell lines of lymphocytes of both t and b origin. it also inhibits [3h]thymidine incorporation in mouse cell lines. normal immunosuppressive protein was able to inhibit the proliferation of these cells, although they were already transformed and had a high rate of dna synthesis. on the other hand, it does not inhibit myeloid cells or fibroblasts.197986450
purification and characterization of a plasminogen activator secreted by cultured human pancreatic carcinoma cells.a plasminogen activator secreted by cultured human pancreatic carcinoma (mia paca-2) cells has been purified to apparent homogeneity by procedures including sepharose-l-arginine methyl ester affinity chromatography, sephadex g-200 gel filtration, isoelectric focusing, and sodium dodecyl sulfate gel electrophoresis. the plasminogen activator shares many properties with urokinase including: molecular weight (55 000), isoelectric point (8.7), heat stability (60 degrees c, 30 min), ph stability (1.5 ...197715590
moloney lymphoma cells express a polyprotein containing the gag gene-coded p15 and the moloney leukemia virus-induced cell surface antigen (mcsa).the relationship between mcsa and the viral structural proteins in yac moloney lymphoma cells was further investigated by using membrane immunofluorescence and immunoadsorbent columns. as previously observed, mcsa showed only minimal capping and thereby differed in behaviour from gp70, p30 and p12 virion antigens. whereas antibody-induced capping of gp70 did not change the membrane distribution of mcsa, co-capping was observed between mcsa and p30 and p12 gag protein antigens. this indicated tha ...197986525
prostacyclin: a solution to some problems of extracorporeal circulation. experiments in greyhounds.in cardiopulmonary-bypass experiments in greyhounds the effects of adding prostacyclin, prostacyclin plus heparin, and heparin alone to the extracorporeal circulation were compared. with heparin alone platelet count and function were reduced, the pressure differential across the arterial filters rose, platelet deposits were found on the arterial filters, and plasma-fibrinogen levels fell. plasma from these dogs was toxic to fetal-mouse hearts in culture. with prostacyclin alone, fibrinogen level ...197986720

early detection of chlamydial inclusions combining the use of cycloheximide-treated mccoy cells and immunofluorescence staining.detection of chlamydia trachomatis inclusions only 21 h after a specimen reaches the laboratory has been achieved by the combined use of cycloheximide-treated mccoy cells and immunofluorescence staining. moreover, cells exposed to cycloheximide were more sensitive for detecting chlamydial inclusions than those pretreated by irradiation, since larger numbers of inclusions were found in the former cells. the application of this rapid and sensitive method allows a diagnosis of chlamydial infection ...197771306
chlamydia trachomatis infection and veneral disease.chlamydia trachomatis was isolated by the irradiated mccoy cell technique from 44 out of 103 men with non-gonorrhoeic urethritis and from 11 out of 15 patients with post-gonococcal urethritis. in women attending the venereal diseases clinics, chlamydial infection was observed in 49 out of 130 patients (38%), an infection incidence of the same order of magnitude as the one noted for gonococcal infection (40%). in 19% both infections occurred simultaneously. treatment with tetracycline eliminated ...197773314

chlamydia trachomatis urethritis in men attending a venereal disease clinic: a culture and therapeutic study.urethral specimens from 459 male patients attending a venereal disease clinic were studied for presence of chlamydia trachomatis and neisseria gonorrhoeae. of the 459 patients, 362 had symptoms suggestive of urethritis. in these 362, gonorrhoea was diagnosed in 78 (22%), while 88 (24%) harboured c. trachomatis; 15 harboured both organisms. of those patients from whom c. trachomatis was isolated, 17% had no subjective symptoms of urethritis; the same percentage of symptomless carriers of gonococc ...197876400
separation and partial characterization of a type-specific antigen from chlamydia trachomatis.type-specific antigens of chlamydia trachomatis have been demonstrated by the mouse toxicity prevention test and a variety of immunofluorescent techniques. in addition, biologic activity has been associated with these antigens in terms of type-specific immunity to trachoma infections. this report is the first to describe the detection of a soluble type-specific antigen of c. trachomatis and its separation from those antigens that cross-react among different immunotypes. test antigens were prepar ...197878941
(exo, exo)-2-aryltropane-3-carboxylic esters, hypoglycemic agents with accompanying analgesic activity.(exo, exo)-2-aryltropane-3-carboxylic esters of types 6, 7, and 10 lower circulating blood glucose levels by 60--80%. this activity is accompanied by an analgesic activity roughly equal to that of codeine. both of these activities reside in the 1r enantiomer and extensive structure-activity studies failed to separate them. the specific opioid antagonist nalorphine blocks the analgesic activity but does not diminish the hypoglycemic action. conformational integrity afforded by the ethylene bridge ...197831482
antibodies against chlamydia of lymphogranuloma-venereum type in crohn's disease.antibodies against chlamydia of lymphogranuloma-venereum type were detected by the micro-immunofluorescence technique in 38 (69%) of 55 patients with crohn's disease. weak positive reactions were seen in only 2 or 21 patients with other gastrointestinal disorders and 1 of 50 healthy blood-donors.197983465
isolation of a type-specific antigen from chlamydia trachomatis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.this report describes the isolation of a type-specific antigen of a serotype a strain of chlamydia trachomatis. the antigen could be identified in sodium dodecyl sulfate-polyacrylamide electrophoretic (sds-page) analysis of immunoprecipitates of homologously reacted lysates from bolton-hunter 125i-labeled elementary bodies, solubilized by sonication and treatment with nonidet p40. the electrophoretic pattern of this precipitate revealed a peak of unique mobility that was not reproduced by hetero ...197984016
growth-stimulating factor in regenerating canine liver.extracts from dog livers which had been regenerating for 24, 48, and 72 h after hepatectomy were infused for 6 h into the left portal vein of animals which had fresh portacaval shunts (eck fistula) and which were killed 2 and 3 days later. the brief exposure to the 48-h and especially the 72-h regenerating liver extracts induced a delayed proliferative response predominantly in the left liver lobes, with a slight spillover effect to the right liver lobes but none to the kidney. the response reac ...197984151
update: drugs in breast milk.drugs found in a woman's blood can be detected in her milk. the concentration in milk depends on the amount of drug in maternal blood, its lipid solubility and degree of ionization, whether it is actively secreted into the milk, and status of maternal renal function. alcohol concentration in the mother's milk is generally about equal to that in her blood; it is not known however, how large a daily dose can be tolerated by an infant. anticoagulants may or may not appear in breast milk. no sig ...197984332

is trachoma an ocular component of a more generalised chlamydial infection?in industrialised countries, inclusion conjunctivitis of the newborn is now known to be just one manifestation of a more generalised infection with chlamydia trachomatis. pneumonia and enteric infection can develop in perinatally infected infants. it is possible that trachoma in developing countries may reflect extraocular infection that may contribute to the high frequency of pneumonia and diarrhoea in infants in these countries. if true, this would explain the short-term effects of topical tre ...197985939
identification of gallbladder typhoid carriers by a string device.the efficiency of a gelatin capsule containing a nylon string for collection of duodenal specimens was investigated in carriers of salmonella typhosa (typhi). cultures of duodenal specimens obtained by means of the string capsule were compared with cultures of duodenal specimens obtained by a conventional duodenal tube and with stool cultures duodenal contents obtained with either the string or tube were more often positive for s. typhosa than were stool cultures. the string, which is as efficie ...197986040
immunogenetics of the mcb1 macroglobulin allotype in cattle.the paper describes a cattle serum antigen (mcb1) which is controlled by a dominant gene (mcb1), independent from those controlling the two macroglobulin markers mca1 and mca2 as well as from that controlling the low-density lipoprotein marker ld1a1. mcb1 is located on a high-molecular-weight serum protein which, very likely, is an alpha2-macroglobulin.197986518
[phospholipids and blood coagulation].after a simplified survey of the chemistry of phospholipids (pl) their presence in the lipid part of thromboplastin is dealt with, the significance of this structure being stressed. in addition, the condition, mode of action and synthesis of pl in blood platelets are extensively discussed and the impact of the composition of thrombocytic pl in the membrane and granular fraction by plasma lipid substances is referred to. the relations between single forms of pl and those proteins activating coagu ...197989981
erythromycin and lymecycline treatment in chlamydia-positive and chlamydia-negative non-gonococcal urethritis--a partner-controlled study.a group of 213 men with non-gonococcal urethritis and their sexual partners were treated either with erythromycin stearate 500 mgx2 for 15 days or with lymecycline 300 mgx2 for 10 or 20 days. chlamydia trachomatis was isolated from 40% of the men, from 26% of their female partners and from 56% of the partners of men with chlamydia-positive urethritis. one hundred and eighty-one men were available for evaluation of therapy. there were no significant differences between the treatment schedules. th ...197987096
involvement of host fc receptors in antibody-mediated cutaneous basophil hypersensitivity reactions.cutaneous basophil hypersensitivity (cbh) reactions are heterogeneous delayed time course basophil-rich responses that can be mediated by either t cells, b cells, or serum antibodies. the current study examined the mechanism by which antibodies mediate cbh in guinea pigs. fc competition experiments were constructed by passively transferring mixtures of anti-klh serum and normal heterologous gamma-globulins. it was found that rabbit igg and its isolated and purified fc fragment [but not the (fab' ...197990094
histological and histochemical changes of the skeletal muscle in human chronic chagas' disease.gastrocnemius muscle biopsies were performed in 7 subjects with chronic chagas' disease. on clinical and laboratory grounds the selected patients were judged to be healthy, being the only abnormality found the presence of positive serum tests for chagas' disease. fibre type grouping of either type i or type ii was observed in 5 of the 7 patients. furthermore, in 2 of the 5 patients showing muscle fibre groupings, angular fibres reacting with nadh and non-specific sterase were also found. these o ...197887186

the intra-nucleolar localization of amplified rdna in xenopus laevis oocytes.a fluorescent feulgen-stain was adapted in order to demonstrate dna-containing structures inside the amplified nucleoli of xenopus laevis. at all stages of oogenesis this method reveals granules or complex structures of dna in each nucleolus. the micronucleoli which do not stain with this method and which do not reveal an internal structure in low molarity saline, unlike real nucleoli are considered as nucleolus-like bodies. the dna-containing structures in the nucleoli can be composed of one or ...197990588

mechanisms of mouse mast cell activation and inactivation for ige-mediated histamine release.the ige-mediated histamine release from mouse mast cells requires ca++, is optimal at 37 degrees c, and is enhanced by phosphatidylserine. the rate of release is relatively slow. the mast cells can be activated to release histamine by either anti-ige or anti-fab antibodies and, in the case of cells from sensitized mice, by the immunizing antigen. the incubation of mast cells with antigen in the absence of ca++ or phosphatidylserine fails to release histamine. such cells are desensitized to the f ...197987441

procaine-induced seizures in epileptic monkeys with bilateral hippocampal foci.intravenous procaine hcl given at low doses (0.5-2.5 mg/kg) to two monkeys with bilateral alumina hippocampal foci depressed interictal spiking or had little effect. at 5.0 mg/kg unilateral limbic activation occurred. at 10.0 mg/kg unilateral or bilateral limbic activation and generalized seizures could be evoked within 3-10 min. at higher doses (15 and 20 mg/kg) bilateral limbic activation or brief (one min) generalized seizures occurred. the unilateral-onset psychomotor seizures were not ident ...197991502
spontaneous histamine secretion from leukocytes in the presence of strontium.basophil leukocytes from human blood secrete histamine in the absence of a membrane stimulus when incubated in a medium containing sr++, 1 to 10 mm. spontaneous histamine secretion in the presence of sr++ is inhibited by la+++, 1 to 1000 nm and 2 deoxy-d-glucose, 30 to 300 microm. spontaneous secretion in the presence of sr++ increases with increasing ph in the range 6.5 to 8.5. agents which cause a rise of intracellular cyclic amp level increase the spontaneous secretion in 194th presence of sr ...197987513
