effect of pasteurella multocida and haemophilus pleuropneumoniae toxins on swine alveolar macrophages.supernatants were obtained from 18 hr. broth cultures of pasteurella multocida strains d82 and d62 (serotype d, toxigenic), kobe 6 (type d, non-toxigenic), a50 and x73 (type a, non-toxigenic), haemophilus pleuropneumoniae serotypes 1, 5 and 6, haemophilus sp. taxon "minor group" (2 strains) and an avirulent serotype 1 strain of h. pleuropneumoniae. the supernates were filtered, ph-neutralized and tested for cytotoxicity after incubation for 18 hours in the presence of swine alveolar macrophage m ...19863765367
structural studies of the capsular polysaccharide from haemophilus pleuropneumoniae serotype 1.the capsular polysaccharide of haemophilus pleuropneumoniae serotype 1 (atcc 27088) was found to be a teichoic acid type polysaccharide of a repeating disaccharide unit composed of 2-acetamido-2-deoxy-d-glucose and d-galactose units. by composition analysis, methylation, partial hydrolysis, dephosphorylation, and one- and two-dimensional 500-mhz proton nuclear magnetic resonance experiments, together with 13c nuclear magnetic resonance studies, it was concluded that the capsular polysaccharide i ...19863768164
purification and characterization of adenine phosphoribosyltransferase from mouse mammary carcinoma fm3a cells in culture.adenine phosphoribosyltransferase has been purified to apparent homogeneity from mouse mammary tumor fm3a cells. the purified enzyme, with a specific activity of 20.6 x 10(6) units/g protein at 30 degrees c, was homogeneous as judged by polyacrylamide gel electrophoresis and ouchterlony double immunodiffusion analysis. the native enzyme had a molecular weight of 44,000 and a subunit composition of 23,000. apparent km values for adenine and 5-phosphoribosyl-1-pyrophosphate (prib-pp) were 6.6 micr ...19863768421
vaccine potential of haemophilus pleuropneumoniae oligosaccharide-tetanus toxoid conjugates.oligosaccharides of smooth-type lipopolysaccharide (lps) and oligosaccharides of rough-type lps were isolated from haemophilus pleuropneumoniae and conjugated to tetanus toxoid by reductive amination. the antigenic and immunogenic characteristics of the oligosaccharides, the oligosaccharide-tetanus toxoid conjugates, and the lps of h. pleuropneumoniae were determined by passive hemagglutination, enzyme-linked immunosorbent assay, and inhibition enzyme-linked immunosorbent assay with antisera pro ...19863770954
quantification by flow microfluorimetry of specific binding of antibody to some serotypes of haemophilus pleuropneumoniae.the cross-reactivity exhibited in various other serological procedures by antisera prepared against some standard laboratory strains representing serotypes 1 to 4 and 6 of haemophilus pleuropneumoniae was also apparent when they were examined by flow microfluorimetry.19863775120
protective efficacy of capsule extracts of haemophilus pleuropneumoniae in pigs and mice.capsular extracts of haemophilus pleuropneumoniae, serotype 1, were mixed with al(oh)3 gel (3 parts extract + 1 part al(oh)3) and used as vaccines in pigs and mice. four preparations were tested in experiment i: nacl and cetavlon (hexadecyltrimethyl ammonium bromide) extracts of both low in vitro passage (lp) and high in vitro passage (hp) culture, respectively. four pigs vaccinated with the nacl extract of the lp strain survived, whereas one of four from each of the remaining vaccine groups and ...19863776093

growth and hemolysin production by haemophilus pleuropneumoniae cultivated in a chemically defined medium.a chemically defined medium (cdm) has been developed which supports both growth and hemolysin production by haemophilus pleuropneumoniae. although the growth rate in stationary cultures was substantially slower in cdm than in trypticase soy broth plus 0.6% yeast extract (tsbye) and slightly slower than in heart infusion broth (hib), extracellular hemolysin activity in cdm was slightly higher than in hib and 16-fold greater than in tsbye. maximum hemolytic activity was produced in cdm in early to ...19863791049
differential effect of plasma protein binding of bupivacaine on its in vivo transfer into the brain and salivary gland of rats.the effect of plasma protein binding of bupivacaine on its transfer into brain and salivary gland was studied using bovine serum albumin, human alpha 1-acid glycoprotein (aag) and human serum. the in vivo brain extraction and salivary gland extraction of [3h] bupivacaine relative to [14c]butanol were determined with an intracarotid injection technique used on rats. the brain extraction varied inversely with the bovine serum albumin (0-7.5%) and aag (0-3.0 mg/ml) concentrations. the salivary extr ...19863795038
intravascular macrophages in lungs of pigs infected with haemophilus pleuropneumoniae.pigs were inoculated intratracheally with a virulent or an avirulent isolate of haemophilus pleuropneumoniae serotype 5 and sacrificed during the first 24 hours post-inoculation. intravascular macrophages were examined by electron microscopic and morphometric techniques. samples of lung were taken from regions with no macroscopic lesions (zone 0), 2.5 to 3.0 cm from lesions (zone 1), and from the immediate edge of lesions (zone 2). those pigs inoculated with the avirulent isolate did not develop ...19863811134
influence of inoculation sites and tumor cell culture techniques on the phenotype of a mixed cartilage- and bone-producing mouse mammary tumor.we have previously reported the characterization of an intraperitoneally (ip) transplantable bone-forming mxt tumor. however, the question was unresolved as whether the bone-forming cells originated from either the host animal or from the neoplasm itself. the present work attempts to answer this question by studying the influences of inoculation sites (subcutaneously, sc; intraperitoneally, ip; in the brain, ib; intracranially, icr) on both the cartilage- and bone-forming tumor phenotypes. furth ...19863813489
similarity principles and intrinsic geometries: contrasting approaches to interspecies scaling.we criticize standard allometric approaches on the grounds that they emphasize scaling to one variable at a time, whereas chemically reactive hydrodynamic systems involved in pharmacokinetic phenomena are of higher dimension. we show that attempts based on mechanical similitude to set a dosage that would be equivalent across species (for example, from mouse to humans) lead to ambiguous results. another failing of standard allometry may be its incapability to accommodate the neoteny of homo sapie ...19863820095
effect of heat treatment on the surface antigens of haemophilus pleuropneumoniae.coagglutination and ring precipitation tests were used to study the effect of heat on the surface antigens of haemophilus pleuropneumoniae strains employing the reference strains belonging to serotypes 1 to 7 and field isolates belonging to serotypes 1, 2, 3, 5, 6 and 7. by immunising rabbits with formalin-fixed whole-cell suspension, antibodies were obtained which sensitised cowan i staphylococcus aureus to coagglutinate antigen preparations which had not been heated, or heated at 56 degrees c, ...19873824843
an evaluation of agglutination and coagglutination techniques for serotyping of haemophilus pleuropneumoniae isolates.a comparative evaluation of rapid slide agglutination, tube agglutination, 2-mercaptoethanol tube agglutination, and coagglutination tests was made for serotyping isolates of haemophilus pleuropneumoniae. the results indicated that a majority of the isolates could be serotyped by any of these tests. but, it was not uncommon to find isolates which were inagglutinable or poorly agglutinable in homologous sera. heat treatment of whole-cell suspensions of such isolates was essential to unmask the se ...19873826860

synthesis and beta-lactamase inhibitory properties of 2 beta-[(acyloxy)methyl]-2-methylpenam-3 alpha-carboxylic acid 1,1-dioxides.p-nitrobenzyl 2 beta-[(benzoyloxy)methyl]-2 alpha-methylpenam-3 alpha-carboxylate was prepared by reaction of p-nitrobenzyl 2-[2-oxo-3 alpha-bromo-4-(benzothiazol-2-yldithio)azetidin-1-yl] -2-isopropenylacetate with silver benzoate in the presence of iodine. the resulting diester was oxidized to the sulfone with potassium permanganate and hydrogen peroxide, and the bromine and p-nitrobenzyl groups were removed by hydrogenolysis to give potassium 2 beta-(benzoyloxy)methyl 2 alpha-methylpenam-3 al ...19853872369
the enteric neural receptor for 5-hydroxytryptamine.an enteric neural receptor for serotonin (5-ht) has been characterized. this receptor was assayed, using 3h-5-ht as a radioligand, by rapid filtration of isolated enteric membranes and by radioautography. in addition, intracellular recordings were made from ganglion cells of the myenteric plexus. high affinity, saturable, reversible, and specific binding of 3h-5-ht was demonstrated both to membranes of the dissected longitudinal muscle with adherent myenteric plexus and the mucosa-submucosa. rad ...19853874089
[familial transmission of deleted chromosome 22 [r(22)p0?] in two normal women].a deleted chromosome 22 resembling a ring chromosome was found in a 27-year-old woman without dysmorphic features nor mental retardation. a similar chromosome was found in her mother.19853876060
serotyping of haemophilus pleuropneumoniae by rapid slide agglutination and indirect fluorescent antibody tests in swine.one hundred and forty-one isolates of haemophilus pleuropneumoniae from iowa and illinois swine were characterized morphologically and biochemically and serotyped by rapid slide agglutination (rsa) and indirect fluorescent antibody (ifa) tests. hyperimmune antisera were produced in rabbits using inactivated whole-cell suspensions of the reference strains for h pleuropneumoniae serotypes 1 to 7 and strain 202, representing the taxon "minor group." cross testing of the reference strains and refere ...19853882026
treatment of hypertension in renal disease.experimental and clinical evidence are summarized that support the hypothesis that enhanced transmission of systemic hypertension to the adapted glomerulus in the setting of reduced nephron mass may be responsible for accelerated vascular and glomerular damage in the hypertensive stage of parenchymal renal disease in man. in experimental models of hypertension associated with reduced renal mass, the kidney appears to be damaged directly by transmission of pressure rather than primarily through v ...19853887904
insulin reversal of cancer cachexia in rats.the anabolic effects of exogenous neutral protamine hagedorn insulin on tumor-bearing (tb) and non-tumor-bearing (ntb) rats were examined. exogenous insulin (2 units/100 g/day) produced similar hypoglycemia in tb and ntb rats. food intake and body weight gain were significantly increased by insulin in ntb rats. in tb rats in an early stage of cachexia, insulin increased food intake and host weight (total body weight minus tumor weight). in tb rats with severe cachexia, insulin increased food int ...19853896470

serological cross-reactivity between a porcine actinobacillus strain and haemophilus pleuropneumoniae.during serological screening of a closed spf-herd free of pleuropneumonia, more than half of the pigs were positive for complement-fixing antibodies to haemophilus pleuropneumoniae. actinobacillus bacteria closely related to a. suis were isolated from tonsillar tissue of 14 out of 20 slaughtered pigs submitted for pathological and bacteriological evaluation. none of the pigs had evidence of respiratory disease. two pigs inoculated endobronchially with a selected actinobacillus strain developed m ...19853926287
biochemical and serological identification of strains of haemophilus pleuropneumoniae.eighteen field isolates of haemophilus pleuropneumoniae were studied biochemically and serotyped using the complement fixation test (cft), agglutination test and the immunodiffusion test. three biochemical tests (v-dependency, camp-reaction and urease activity) were found to be very useful for the biochemical characterization of the h. pleuropneumoniae. haemolysis on blood agar plates, although present, was not sufficiently pronounced in all cases to warrant absolute dependence on this character ...19853929457
synthesis of dihomoprostaglandins from adrenic acid (7,10,13,16-docosatetraenoic acid) by human endothelial cells.human umbilical vein endothelial cells were found to contain adrenic acid (22:4) in their cellular lipids. since this fatty acid may be metabolized by cyclooxygenase in the kidney, the metabolism of adrenic acid was studied in endothelial cell cultures. [14c]adrenic acid was metabolized to several more polar metabolites. two of these metabolites co-migrated on hplc with 1 alpha,1 beta-dihomo-8-ketoprostaglandin f1 alpha (the metabolite of 1 alpha, 1 beta-dihomoprostaglandin i2) and 1 alpha,1 bet ...19853931686
gastric mucosal damage in sepsis--effects of pretreatment with a synthetic prostaglandin e1 analogue.an experimental model was used which includes intragastric instillation of 80 mm hcl and 0.6 ml bile/kg followed by intravenous infusion of live e coli in cats for up to three hours. this procedure regularly induces gastric mucosal ulcerations. mucosal blood flow was measured by microspheres before, early, and late in sepsis. total gastric blood flow was recorded electromagnetically. mucosal regeneration capacity as reflected by the rna/dna ratio was measured. misoprostol (a pge1 analogue) was i ...19853932138

morphological and biochemical comparison of virulent and avirulent isolates of haemophilus pleuropneumoniae serotype 5.capsular structure and biochemical composition varied between two isolates (virulent and avirulent) of haemophilus pleuropneumoniae serotype 5. the presence of capsule was determined by transmission electron microscopy with glutaraldehyde-osmium, ruthenium red, alcian blue, and phosphotungstic acid staining procedures. the virulent isolate of h. pleuropneumoniae had a distinct, adherent capsule. the avirulent isolate had a fragile, easily removed capsule. capsular material (cm) and a lipopolysac ...19863943895
isolation, purification, and partial characterization of a lipopolysaccharide from haemophilus pleuropneumoniae.lipopolysaccharide (lps) from haemophilus pleuropneumoniae 1536, serotype 2, was isolated and purified by a procedure designed to be equally satisfactory for both smooth- and rough-type lps. the lps yield was 53%. analysis of the preparations revealed that protein, nucleic acid, and cellular phospholipid contamination was negligible (less than 0.1%). analysis of the sugar content of the lps by gas-liquid chromatography and colorimetric analysis revealed the presence of rhamnose, mannose, galacto ...19863943899
interaction between heat-stable hemolytic substance from haemophilus pleuropneumoniae and porcine pulmonary macrophages in vitro.cytocidal and anti-phagocytic effects of the heat-stable hemolytic substance produced in culture supernatant by haemophilus pleuropneumoniae serotype 2 on porcine pulmonary macrophages (pmp) were investigated in vitro. the substance was partially purified by sucrose density gradient ultracentrifugation, and it seems to be a carbohydrate. the partially purified preparation of the heat-stable carbohydrate with hemolytic activity was used as h. pleuropneumoniae hemolysin throughout this study. viab ...19863943901
a functional organization of on and off pathways in the rabbit retina.intracellular electrophysiological recordings were obtained from amacrine and ganglion cells in an isolated, superfused retina-eyecup preparation of the rabbit. cells were characterized physiologically, after which cell-staining was accomplished by intracellular iontophoresis of hrp. a computer-assisted image-processing system was used to study the dendritic stratification pattern of hrp-labeled neurons within the inner plexiform layer (ipl). our results support the concept that the ipl is funct ...19863944611
complement activation and adult respiratory distress syndrome during intermittent flow apheresis procedures.we observed complement (c) activation during intermittent flow apheresis procedures (haemonetics model 30) in four subjects, two of whom developed adult respiratory distress syndrome (ards). actual c3 conversion during apheresis was illustrated by the finding of significantly elevated c3d levels (p less than 0.05) and of significantly increased alpha-1-antitrypsin/c3 ratios (p less than 0.05) in postapheresis serums. similarly, marked granulocyte aggregating activity was found in these serums, i ...19863946010

incidence, economic effects, and control of haemophilus pleuropneumoniae infections in pigs.this thesis synopsis reports the results of investigations on: the incidence of clinical and subclinical h. pleuropneumoniae infections on pig farms in north brabant; the economic loss on fattening farms; the effect of husbandry; the possibility of eradicating h. pleuropneumoniae on infected breeding farms on the basis of serological testing; the possibility of control on fattening farms by means of vaccination. the principal findings were as follows: clinical and subclinical h. pleuropneumoniae ...19863962149
mesothelial healing: morphological and kinetic investigations.by using structural, kinetic and irradiation techniques it is possible to show that mesothelial healing is a local event. initially, macrophages occupy the surface of a wound on the injured visceral layer, while mesothelial proliferation proceeds at the edge of the wound and the opposing parietal surface. fibrin is formed on the wound surface within 24 h, even in the absence of much haemorrhage. mesothelial ingrowth begins with isolated cells migrating from the wound edge as well as from the ser ...19853973769
metastatic nontraumatic clostridium septicum osteomyelitis.nontraumatic clostridial infections are rare, but need to be diagnosed and treated early or high morbidity and mortality rates result. we believe that this is the first reported case of metastatic nontraumatic clostridium septicum osteomyelitis. early treatment with surgical debridement and parenteral antibiotics without hyperbaric oxygen was used. an associated occult rectal malignancy was discovered and treated.19853980945
comparative virulence of porcine haemophilus bacteria.the virulence of strains of haemophilus pleuropneumoniae serotype 1, 2, 3, 7 and strains of the "minor-group" and haemophilus parasuis were compared by inoculating specific pathogen-free pigs into the lower airways with specified doses of bacteria. haemophilus pleuropneumoniae, strain w, serotype 1, given in 1 x 10(8) colony-forming units, produced a lethal acute pleuropneumonia in four pigs. nonlethal localized pulmonary necrosis was induced in four groups of two pigs given 1 x 10(7), 1 x 10(6) ...19853986682
pulmonary artery wedge pressure may fail to reflect left ventricular end-diastolic pressure in dogs with oleic acid-induced pulmonary edema.we investigated the accuracy with which pulmonary artery wedge pressure (wp) reflected left ventricular end-diastolic pressure (lvedp) in dogs with oleic acid-induced pulmonary edema. we compared hemodynamic variables before and during edema, as measured from a pulmonary artery catheter placed before oleic acid (pa-1) and from a second catheter (pa-2) placed 2 h after oleic acid infusion. oleic acid decreased arterial oxygen saturation and cardiac output and increased pulmonary vascular resistan ...19853996001
[studies on the mechanism of the estrogen action in human breast cancer].only some 50% of estrogen receptor positive breast cancer patients respond to hormone therapy. it is possible that the mechanism of the estrogen action is disturbed in malignant cells. in order to determine which steps of the mechanism are disturbed, cytoplasmic estrogen and progesterone receptor and nuclear estrogen receptor were studied in 217 cases of human breast cancer. thirty breast cancer tumors were examined for nuclear translocation of estradiol in vitro. the assessment of the transloca ...19853999388

hypertension during chronic peripheral and central infusion of angiotensin iii.recent studies have suggested that the angiotensin ii (ang ii) metabolite [des-asp]ang ii (ang iii) may be nearly equipotent with the parent compound in causing several acute neural responses known to be stimulated by angiotensin peptides (i.e., drinking, augmentation of sympathetic neurotransmission, and centrally mediated pressor responses). because neural actions of ang ii are thought to contribute importantly to the ability of this hormone to cause chronic hypertension, the purpose of the pr ...19854025541
cardiopulmonary effects of hypertonic saline in canine oleic acid-induced pulmonary edema.vasoactive drugs may increase intrapulmonary shunt in patients with permeability edema. because 7.5% hypertonic saline solution has cardiotonic properties, we studied its hemodynamic and pulmonary effects in a canine model of oleic acid-induced lung injury. immediately after saline infusion, there were increases in cardiac output (2.0 +/- 0.1 to 3.4 +/- 0.2 l/min; p less than .001) and intrapulmonary shunt (50.3 +/- 4.4 to 57.3 +/- 3.2%; p less than .01) without alteration in arterial or mixed v ...19854028751
