| [preventive and therapeutic application possibilities of newer antibiotics (author's transl)]. | today, however aminoglycosides are nearly indispensable owing to their broad antibacterial spectrum and genuine bactericidal effect as well as the possible synergic effect with beta-lactam preparations. the new cephalosporins are distinguished by a high beta-lactam stability and are active against the majority of pathogens causing nosocomial infections. an exceptional position is held by cefotaxim with its generally outstanding antibacterial potency, and by cefoxitin with its activity against ba ... | 1979 | 114782 |
| measles virus induced lectin binding in cultured, aortic cells. | using the indirect hemadsorption test it was shown that cultured diploid cells of mini-pig, monkey or human aortic origin develop wheat germ lectin/wga/binding capacity following infection with measles virus. heteroploid cell lines of similar origin have bound wga also without being infected with virus. the possible role of virus induced membrane changes in vascular cell pathology is suggested by the results presented. | 1979 | 114964 |

| nitroblue tetrazolium (nbt) reduction by bacteria. some properties of the reaction and its possible use. | all the s. albus, e. coli and p. aeruginosa strains examined reduced nitroblue tetrazolium (nbt) to dark blue formazan. the amount of formazan produced was proportional to the number of bacteria. under the same growth conditions, an equal number of bacteria of various strains produced different amounts of formazan. however, there were statistically verified differences in the nbt-reduction between the three species examined. the nbt-reduction took place in all phases of growth but was most inten ... | 1979 | 115226 |
| pharmacological modification of experimental tardive dyskinesia. | cebus apella monkeys subjected to chronic haloperidol administration develop neurologic disturbances very similar to neuroleptic-induced acute dystonia human beings. after varying lengths of time, certain monkeys develop a prolonged dyskinetic syndrome resembling tardive dyskinesia (td), as seen clinically. two monkeys with signs of td were given single intramuscular injections of various compounds with known effects on the catecholaminergic, cholinergic, serotoninergic and gaba-ergic neurotrans ... | 1979 | 115227 |
| a pharmacological and in vitro comparison of three oral cephalosporins. | the pharmacology of cephradine, cephalexin and a new oral cephalosporin, cefaclor, has been compared in six volunteers. cefaclor was absorbed rapidly and was cleared from the serum more rapidly than the other two agents. this was probably partially due to its instability in serum at body temperature, which was investigated. against a wide range of common pathogens cefaclor was the more active oral cephalosporin. in particular the activity against neisseria gonorrhoeae and haemophilus influenzae ... | 1979 | 115833 |
| commissural columns in the sensory-motor cortex of monkeys. | callosally projecting cells and the terminal ramifications of their axons were identified in the monkey sensory-motor cortex by retrograde and anterograde labeling techniques, often by double labeling cells and axons in the same animal. bundles of callosal fibers terminate in small column-like zones 0.5-1 mm wide in the motor cortex (area 4) and in the first (si) and second (sii) somatic sensory areas. such columns are aligned in register to form elongated strips extending mediolaterally in the ... | 1979 | 115905 |
| [an experimental study on pseudomonas osteomyelitis with special reference to the production of experimental osteomyelitis in mice (author's transl)]. | i) the author has successfully produced a model of experimental osteomyelitis caused by pseudomonas aeruginosa using the following procedure though such a demonstration has been said to be very difficult. after impregnation in a solution containing about 10(5) pseudomonas aeruginosa, 3 mm silk thread of no. 5 was dried under low-pressure atmosphere and then inserted into the metaphysis of right tibia of a mouse. this method can be produced experimental osteomyelitis in 100% of the animals. in th ... | 1979 | 115949 |

| restriction of plasmid-mediated transformation in bacillus subtilis 168. | when plasmids carrying leucine genes of bacillus subtilis 168 were isolated from a restriction and modification deficient (r-m-) strain and used for transformation of a restricting strain b. subtilis 168 leu rece4, the number of transformants was greatly reduced. transformation of rec+ strain (transformation by integration of the donor dna into the chromosome) with the plasmids was not affected irrespective of whether the recipient carried the r+ or r- phenotype. these results show that the plas ... | 1979 | 117281 |
| study of the anti-tumor effect of polypeptide pineal extract. | bovine pineal polypeptide extract (ppe) exerted an anti-tumor effect on mouse-transplantable tumors: mammary cancer (rsm), squamous cell cervical carcinoma (scc), hepatoma-22a and lympholeukemia lio-1, and had no effect on harding-passey melanoma and leukemia l-1210. it was shown that ppe possessed the ability to decrease the incidence of dmba-induced mammary adenocarcinomas in rats. the daily administration of 0.5 mg ppe prolonged the life span of rats by 25% and failed to influence spontaneous ... | 1979 | 117414 |
| cost-benefit studies of vaccinations in finland. | the benefits of vaccination are, in general, recognized. for some diseases these benefits are obvious. when starting or evaluating new vaccination programmes, a more critical approach is needed. before starting vaccination against measles and rubella in finland a cost-benefit study was performed. according to those studies the net benefits of each vaccination would be ca. 100 million finnish marks in 25-30 years. those benefits not measurable in money value of human life, decrease of suffering, ... | 1979 | 118069 |
| [modelling modification of chemical mutagenesis in human cells. iii. linear index of protection as the standardized criterion of modification]. | the effect of substances with radioprotective activity, apaetp 2,3 (aminopropylaminoethylthiophosphoric acid 2,3), apaetp 3,3 and cystaphos, on chromosome aberrations, induced by thiotepa in the culture of human lymphocytes was investigated. it is shown that the obtained curves "concentration -- effect" for thiotepa can be described by equations rho = 1 -- e-(kc + alpha)2 and x = e -(kc + alpha)2 --1 for aberrant cells and for chromosome breaks in the presence of the investigated substances. on ... | 1979 | 118079 |
| isolation and characterization of recombinant dna plasmids carrying drosophila trna genes. | recombinant plasmids carrying drosophila melanogaster trna genes were constructed by ligation of hindiii-cleaved drosophila dna to hindiii cut pbr322 dna. 90 clones were isolated that contained genes for one or more of eleven trnas. 43 of the plasmids were characterized by a number of methods: restriction nuclease digestion; agarose gel electrophoresis; hybridization with individual, purified, 125i-labelled drosophila trna molecules and in situ hybridization to drosophila chromosomes. the result ... | 1979 | 118082 |
| significance of the detection of beta-galactosidase and of beta-xylosidase in the taxonomic study of the genus haemophilus. | a total of 314 strains of haemophilus, isolated from clinical samples, were studied for the production of beta-galactosidase and beta-xylosidase. none of the h. influenzae strains studied (9 beta-lactamase positive strains and 129 beta-lactamase negative strains) possessed these enzymes. both enzymes were almost constantly observed among strains of h. paraphrophilus (10 strains studied) and of h. paraphrohaemolyticus (9 strains studied). among the other species (h. parainfluenzae, 55 strains; h. ... | 1979 | 118191 |
| comparison of two antigen detection techniques in a primate model of haemophilus influenzae type b infection. | rapid diagnosis of haemophilus influenzae type b meningitis is possible using immunological tests for capsular antigen (polyribophosphate, prp), such as countercurrent immunoelectrophoresis (cie) and latex particle agglutination (lpa). we compared two tests in monkeys with evolving, serially quantitated h. influenzae type b bacteremia (n = 23) and meningitis (n = 21). in vitro, the lpa test was sensitive to 0.5 ng of prp/ml of saline, and the cie test was sensitive to 1.0 ng/ml; in serum, howeve ... | 1979 | 118934 |
| serological grouping of meningococci and encapsulated haemophilus influenzae strains by latex agglutination. | the latex agglutination method, utilizing antibody-coated latex particles, was adapted for serogrouping of neisseria meningitidis and serotyping of encapsulated haemophilus influenzae strains from agar plates. it was found to give more clear-cut results than conventional slide agglutination. a 100% agreement with the antiserum agar method was found for all strains isolated from blood or cerebrospinal fluid. many meningococcal strains from nasopharyngeal carriers are autoagglutinable, but some of ... | 1979 | 118981 |

| experimental studies on the mechanism of the nitroglycerin effect. | the regional decrease of the speed and extent of the contraction and the relaxation of the canine myocardium induced by coronary ligation was enhanced by intravenously administered nitroglycerin (gtn), simultaneously with the decrease of the left ventricular pressure, while the increase of myocardial fiber length caused by that procedure was partly abolished. the above changes could be reproduced by gtn applied directly onto the ischaemic myocardial surface even before the decrease of the left v ... | 1979 | 120673 |
| [measles and temporary increase in masculine births: coincidence or causality?]. | data from three west-african populations shows significant increase of sex-ratio. in two of them a considerable excess of male births came from conceptions the year following an epidemic of measles. this is limited to the villages affected by this epidemic. these facts seem to be similar to those related to hepatitis and sex-ratio. they suggest similarities between measles virus and surface antigens of y sperms. this hypothesis could be tested by immunological investigation. | 1979 | 120780 |
| [identification of a virus similar to hepatitis b virus in non-a non-b hepatitis]. | hepatitis b virus-like particles (including dane particles) with dna polymerase activity but negative for hbs ag have been identified in non-a, non-b hepatitis sera positive for hc ag. although specifically associated with the particles, hc ag is not a surface antigen of the hepatitis c virus identified here for the first time. the relationship of this agent with hbv seems obvious, and deserves further study. | 1979 | 120782 |
| [vitamin d and reproduction in wistar rats]. | females have received from weaning a semi-synthetic diet (0,35% ca; 0,32% p; 0,03% mg), with or without vitamin d (+/- d). fertility of these females was not changed. at weaning, the young from mothers--d had lower weight, calcemia and phosphatemia, but the ash content of the femur was the same as for young from mothers + d. young rats from mothers +/- d were given the diet with or without vitamin d. 19 days after weaning, the diet of the mother (+/- d) appears to be the principal factor for gr ... | 1979 | 120790 |

| ischemic brain edema: comparative effects of barbiturates and hypothermia. | the effect of pentobarbital and hypothermia on the development of ischemic brain edema was studied in 23 rhesus monkeys undergoing transorbital middle cerebral artery occlusion. fifteen additional animals served as unclipped controls. regional cortical cerebral blood flow (rcbf), arteriovenous oxygen content difference (avdo2), and regional cortical metabolic rate of o2 (rcmro2) were measured hourly until sacrifie 11 hours postocclusion, at which time ischemic cerebral edema was measured. in 8 a ... | 1979 | 107624 |
| interpretation of serum and red cell folate results. a comparison of microbiological and radioisotopic methods. | serum folate and red blood cell folate levels were measured in 167 patients using a microbiological method (lactobacillus casei) and a commercial 125i radioassay kit. the results of the two methods were compared and related to the clinical findings to see which method more truly reflected the physiological folate status of the patient. there was a good linear correlation between the methods for both serum folate and red cell folate over the whole range encountered and the mean results obtained w ... | 1979 | 107505 |
| [anabolic effects of steroid hormones in rabbits (author's transl)]. | the anabolic effect of steroid hormones was investigated in rabbits by measuring the skeletal accumulation rate of 85sr following the continuous administration of estrogens, androgens and corticosteroids over a period of eight weeks. androgenic hormones did not influence the accumulation rate of 85sr, whereas following castration and prolonged administration of estrogens an increase of 85sr accumulation was found. there was no correlation of the changes observed with serum calcium levels, since ... | 1979 | 107513 |
| survival of transplanted normal hepatic cells in bilirubin udp-glucuronyl transferase deficient gunn rat liver. | the survival of h3 thymidine labelled normal rat hepatic cells after transplantation into the gunn rat liver has been investigated. it was found that 0.9% of the cells survived at least 12 weeks after transplantation. this suggests that the observed uridine diphosphoglucuronyl transferase (udpgt) activity in the genetically deficient gunn rats after transplantation of normal liver may be partially due to these cells. time required for the transplantation procedure has a profound effect on the su ... | 1979 | 107547 |
| immunoglobulins g, a and m in normal and pathologic human sera determined with the spot immunoprecipitate assay (sia) in multi-assay plates. | a simple rapid spot immunoprecipitate assay (sia) is presented. the antigen--antibody reaction takes place in a field of alternating current; small amounts of specific antisera are used, and the influence of diffusion or electromobility of the antigen is avoided. determinations of igg, iga and igm in sera from healthy individuals correlated highly significantly with radial immunodiffusion (rid) results. the reaction conditions in sia, particularly the availability of a sufficiency of specific an ... | 1979 | 107578 |

| thyroid function in preterm infants with respiratory distress syndrome. | thyroid function was evaluated in premature infants 30 to 35 weeks ega with severe rds and was compared to that of healthy control subjects of similar ega. the infants with rds had significantly lower serum levels of t3, t4, and ft4i during the first 60, 90, and 30 days, respectively, and had elevated t3ur during the first 10 days. the mean (+/- sd) postdelivery tsh peak was lower in the rds group (32.8 +/- 9.6 muu/ml) than in the control group (60.9 +/- 21.8 muu/ml; p less than 0.005). after tr ... | 1979 | 107304 |
| central effect of taurine and its analogues on fever caused by intravenous leukocytic pyrogen in the rabbit. | 1. taurine infused i.c.v. after i.v. injection of leukocytic pyrogen (lp) inhibited the initial rise in body temperature and prolonged fever when infusion was stopped. 2. similar infusion of taurine also inhibited the hypertermic effect of i.c.v. pge2 (0.5 microgram) but did not cause prolonged hyperthermia. 3. i.c.v. administration of the taurine analogues hypotaurine and beta-alanine, compounds which have been shown previously to compete with taurine for facilitated transport in c.n.s. tissue, ... | 1979 | 107309 |
| percutaneous nitroglycerin absorption in rats. | percutaneous nitroglycerin absorption was studied in shaved rats by monitoring unchanged plasma drug concentrations for up to 4 hr. drug absorption from the neat liquid state or from an alcoholic solution was considerably poorer than that from a commercial ointment. this observation was unanticipated since the driving force for percutaneous drug absorption was assumed to be drug thermodynamics. potential artifacts such as drug volatilization from the skin, reduction of surface area through dropl ... | 1979 | 107313 |

| deoxythymidine nucleotide metabolism in bacillus subtilis w23 infected with bacteriophage sp1oc: preliminary evidence that dtmp in sp10c dna is synthesized by a novel, bacteriophage-specific mechanism. | despite the fact that mature sp10c dna contains dtmp, the acid-soluble fraction of infected cells contained no dttp during the interval of phage replication. however, infected cells contained normal cellular levels of datp, dgtp, and dctp. upon infection of deoxythymidine-starved bacillus subtilis m160 (a deoxythymidine-requiring mutant of b. subtilis w23), mature phage dna with a normal dtmp content was made. sp10c codes for an enzyme that seems to catalyze the tetrahydrofolate-dependent transf ... | 1979 | 107324 |

| serotypes and antibiotic susceptibilities of pseudomonas aeruginosa isolates from single sputa of cystic fibrosis patients. | a phenotypic characterization of pseudomonas aeruginosa from single sputum samples of 21 typical cystic fibrosis patients indicated a high frequency of heterogeneity among isolates on the basis of differences in antibiotic resistance, colony morphology, pigmentation, and serotype. two or more isolates with different but stable susceptibilities to carbenicillin, gentamycin, streptomycin, tetracycline, chloramphenicol, and sulfamethoxazole plus trimethoprim were detected in 38% of the sputa. diffe ... | 1979 | 107186 |

| association of beta-glucosidase with intact cells of thermoactinomyces. | the location of the b-glucosidase activity in a whole culture broth of the thermophilic organism thermoactinomyces has been studied. little beta-glucosidase activity was found in the culture filtrate, while the culture solids contained the major part of the activity of the whole culture broth. the activity does not appear to be adsorbed to the culture solids; rather there is evidence that it is an intracellular soluble enzyme(s). the ph and temperature optima for a crude beta-glucosidase prepara ... | 1979 | 106906 |
| [modeling of determinant and dependent foci of epileptic activity in the rat cerebral cortex]. | foci of increased excitability were created in acute experiments on rats by means of weak strychnine solutions working at independent regimens. the hyperactive excitability focus induced by means of concentrated strychnine solutions played the role of a determinant structure. the importance of the latter is in the fact that it determines the activity character of other epileptogenic foci, enhances their convulsive activity, unites them into a single functional complex and determines the behaviou ... | 1979 | 106910 |
| production, purification, and properties of dextransucrase from leuconostoc mesenteroides nrrl b-512f. | the production of dextransucrase from leuconostoc mesenteroides nrrl b-512f was stimulated 2-fold by the addition of 0.005% of calcium chloride to the medium; levansucrase levels were unaffected. dextransucrase was purified by concentration and dialysis of the culture supernatant with a bio-fiber 80 miniplant, and by treatment with dextranase followed by chromatography on bio-gel a-fm. a 240-fold purification, with a specific activity of 53 u/mg, was obtained. contaminating enzyme activities of ... | 1979 | 106966 |

| [multiple molecular forms of erythrocyte carbonic anhydrase of sheep (author's transl)]. | three major forms ci, cii and cx and the minor component ci1v of ovine erythrocyte carbonic anhydrase have been identified in the ethanol chloroform extract of the hemolysate by electrophoresis on cellulose acetate and isoelectrofocusing. isolation of the four forms was achieved by chromatography on deae-sephadex a-50. comparative studies suggest that: (1) form ci1v is a modified form of ci, (2) form cx is ci plus glutathione and (3) forms ci and cii are isoenzymes which differ in their primary ... | 1979 | 106895 |
| artifacts in isoelectric focusing of the microsomal enzymes cytochrome p-450 and nadph-cytochrome p-450 reductase. | highly-purified rat liver microsomal cytochrome p-450 and nadph-cytochrome p-450 reductase (nadph-ferricytochrome oxidoreductase, ec 1.6.2.4) preparations gave rise to a large number of bands under a variety of isoelectric focusing conditions, as observed after staining for either zymogen or protein. the binding patterns were not independent of sample concentration and position of application, and eluted bands did not refocus as expected. the artifactual heterogeneity is attributed to strong pro ... | 1979 | 106898 |
| animal models for the comparative assessment of neurotoxicity following repeated administration of vinca alkaloids. | neurotoxicity is the major side effect occurring during the clinical use of vincristine (vcr). animal models predictive of potential neurotoxicity would be very useful in the preclinical development of new vinca compounds. to simulate conditions in which neurotoxicity is produced during the clinical use of vcr, experimental animals (except the guinea pig) were given the test compounds by the iv route over a prolonged time period. doses were selected based on the production of leukopenia. vindesi ... | 1979 | 105807 |
| measurement in vivo of hydrogenase-catalysed hydrogen evolution in the presence of nitrogenase enzyme in cyanobacteria. | a method was devised that allows measurement in vivo of hydrogenase-catalysed h2 evolution from the cyanobacterium anabaena cylindrica, independent of nitrogenase activity, which is also present. addition of low concentrations of reduced methyl viologen (1-10mm) to intact heterocystous filaments of the organism resulted in h2 evolution, but produced conditions giving total inhibition of nitrogenase (acetylene-reducing and h2-evolving) activity. that the h2 formed under these conditions was not c ... | 1979 | 106842 |
| investigation of the organization of rhodopsin in the sheep photoreceptor membrane by using cross-linking reagents. | the organization of rhodopsin in the photoreceptor membrane of sheep rod outer segments was investigated by using a variety of bifunctional reagents. of the nine reagents used, seven gave oligomeric opsin species, whereas two, copper phenanthroline and dithiobisphenyl azide, failed to cross-link the protein. in general, the cross-linked species obtained showed diminishing yields from dimer to tetramer, together with some higher-molecular-weight aggregates. it is proposed that the patterns of cro ... | 1979 | 106845 |
