purification and characterization of an extracellular cytolysin produced by vibrio vulnificus.	an extracellular cytolytic toxin produced by the halophilic bacterium vibrio vulnificus was isolated free of detectable contamination with medium constituents and other bacterial products by sequential ammonium sulfate precipitation, gel filtration with sephadex g-75, hydrophobic interaction chromatography with phenyl-sepharose cl-4b, and isoelectric focusing in an ethylene glycol density gradient. the cytolysin is a heat-labile, hydrophobic protein that is inhibited by large amounts of choleste ...	1985	3980095
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.	1985	3980945
molecular mechanisms of olfactory reception. vi. kinetic characteristics of camphor interaction with binding sites of rat olfactory epithelium.	camphor binding to a possible receptor of rat olfactory epithelium has been studied within the ligand concentration range 10(-11)-10(-6) m. at these concentrations camphor is bound by a set of receptors. they are distinguished by both the affinity to the ligand (k1 = 5 x 10(-10) m, k2 = 3.5 x 10(-8) m, k3 approximately equal to 10(-6) m) and their amount in the epithelium. the differences in the affinities are due to different values of the association rate constant of camphor (k1), which varies ...	1985	3986222
vibrio vulnificus. man and the sea.	to identify risk factors for vibrio vulnificus infections, we performed a regional case-control study of 19 patients identified by isolates received at a state reference laboratory. interviews with patients or surviving relatives and with three controls for each patient were compared in a matched analysis. patients with v vulnificus wound infection were more likely than controls to have sustained a puncture wound while handling fresh seafood or to have been exposed to salt water. more patients w ...	1985	3989959

surgical treatment for infective endocarditis--decision tree for the treatment and introduction of translocation method.	persistent fever during active-phase ie is an indication for surgical treatment in the light of the causative organism and the underlying disease. to counter worsening hemodynamics, surgery may be the only feasible way. surgery is performed when the patient does not respond to vasodilators and he shows an fs of less than 25%. the introduction of translocation provides a solution for the treatment of active ie. lesions, vegetations more than 5 mm in diameter, periannular abscess, and mycotic aneu ...	1985	4021068
topographic organization of projections from the amygdala to the hypothalamus of the rat.	afferent fibers from the amygdala to subdivisions of lateral, ventromedial and dorsomedial hypothalamic nuclei were investigated in rat by retrograde transport of horseradish peroxidase. small (intranuclear size) peroxidase deposits were placed in hypothalamic nuclei by iontophoresis of a tracer solution containing poly-l-alpha-ornithine which greatly limited diffusion. the medial, central and amygdalo-hippocampal nuclei of the amygdala were found to be the major donors of amygdaloid afferent fi ...	1985	4022458
detection of reticulo-endothelial blockade with low-dose test agent.	blood clearance and organ extraction of a low-dose reticulo-endothelial test agent, technetium labelled tin colloid (ttc), was measured in groups of rabbits pretreated with reticulo-endothelial blocking agents. electron microscopy and ultrastructure analysis confirmed that kupffer cells extracted ttc. pretreatment with silica caused reduced kupffer cell uptake and spillover of ttc into the spleen. pretreatment with sheep red cells caused reduced kupffer cell uptake and reduced splenic uptake but ...	1985	4027180
vibrio vulnificus resists phagocytosis in the absence of serum opsonins.	invasive disease caused by vibrio vulnificus may result partially from resistance to phagocytic host defense mechanisms. the present studies show that v. vulnificus resists phagocytosis by murine peritoneal macrophages in the absence of serum opsonins and extracellular bacterial products, apparently through the anti-phagocytic properties of the bacterial surface.	1985	4030101

antiarrhythmic and electrophysiologic actions of clofilium in experimental canine models.	clofilium was studied in three experimental models. in non-ischemic and chronically infarcted canine hearts, clofilium (0.5-2 mg/kg) produced a dose-dependent increase in electrical ventricular fibrillation threshold (vft), but prolonged the effective refractory period (erp) of normal myocardium in only the non-ischemic heart. when chronically infarcted hearts were subjected to programmed electrical stimulation, 1 mg/kg of clofilium inhibited the re-induction of either ventricular tachycardia or ...	1985	4054216
characterization of a mitochondrial transport system for branched chain alpha-keto acids.	efflux of branched chain alpha-keto acids from preloaded rat heart mitochondria was slow at low external ph. efflux was first order, and measured rate constants, kappa efflux, were 0.104 +/- 0.005 and 0.115 +/- 0.006 min-1 for alpha-ketoisovalerate and alpha-ketoisocaproate (kic), respectively. efflux was stimulated significantly by branched chain alpha-keto acids and related carboxylates such as alpha-ketocaproate and alpha-ketovalerate, but not by substrates for the pyruvate transporter. kic w ...	1985	4055776
comparison of api 20e, api rapid e, and api rapid nft for identification of members of the family vibrionaceae.	sixty isolates, from nine species of the family vibrionaceae, were tested by the api 20e, api rapid e, and api rapid nft systems. results were compared with those obtained with standard biochemicals. included were 7 aeromonas caviae isolates, 27 aeromonas hydrophilia isolates, 10 aeromonas sobria isolates, 3 plesiomonas shigelloides isolates, 3 vibrio alginolyticus isolates, 3 vibrio cholerae isolates, 1 vibrio fluvialis isolate, 5 vibrio parahaemolyticus isolates, and 1 vibrio vulnificus isolat ...	1985	4056003

some properties of vibrio vulnificus hemolysin.	some properties of hemolysin produced by vibrio vulnificus were investigated. the hemolysin was heat labile, and the hemolytic activity was inhibited by adding cholesterol or divalent cations. cholesterol inhibited the temperature-independent hemolysin-binding step, suggesting that cholesterol made up the binding site of the cell membrane, whereas the divalent cations inhibited the temperature-dependent membrane-degradation step. however, the v. vulnificus hemolysin was stable to oxygen and sulf ...	1985	4088099
uptake and clearance of vibrio vulnificus from gulf coast oysters (crassostrea virginica).	oysters collected in late winter, when they were free of vibrio vulnificus, were exposed in the organism in the laboratory. the oysters effectively concentrated the bacteria from seawater, but when the inoculum was removed, the bacteria were rapidly cleared from the oyster tissues. these results suggest that v. vulnificus may be found in oysters as a result of filtration of the bacteria from seawater rather than active multiplication of the bacteria in the oysters.	1985	4091570
[an experimental study on adhesion blocking in simultaneous injury of tendon and nerve].	the formation of adhesions between simultaneously injured tendon and nerve with and without adhesion blocking materials was studied by using a rabbit model. a collagen membrane, produced from adult bovine corium and with a negative electric charge induced by chemical modification, was used as the blocking material. microangiography and histological studies were performed to investigate the vascular supply to the adhesions. the following results were obtained. blood vessel proliferation was obser ...	1985	3831164

isolation and characterization of neuropeptide y from porcine intestine.	the isolation and primary structure of intestinal neuropeptide y (npy) is described. the peptide was purified from porcine intestinal extracts using a chemical assay and radioimmunoassay for npy. the amino acid sequence of this peptide is: tyr-pro-ser-lys-pro-asp-asn-pro-gly-glu-asp-ala-pro-ala-glu-asp-leu-ala- arg-tyr-tyr- ser-ala-leu-arg-his-tyr-ile-asn-leu-ile-thr-arg-gln-arg-tyr-nh2. this the structure of intestinal npy is identical to the npy of brain origin.	1985	3838090
chemoattractants in fibrotic disorders.	fibrosis represents an excessive deposition of connective tissue which impedes the normal functions of an organ or tissue. the mechanisms leading to this increased deposition of connective tissue may be similar to those occurring in normal wound repair. we have previously shown that the repair process involves the migration of connective tissue cells to the site of injury and their subsequent proliferation. one of the principal factors controlling these events appears to be the platelet-derived ...	1985	3851719
human c-myc and n-ras expression during induction of hl-60 cellular differentiation.	the genome of the human hl-60 promyelocytic leukemia cell contains amplified c-myc sequences and the transforming n-ras oncogene. the present study has monitored c-myc and n-ras expression in hl-60 cells during induction of myeloid and monocytic differentiation with dimethyl sulfoxide, hexamethylene bisacetamide, 12-o-tetradecanoylphorbol-13-acetate and 1,25 dihydroxy-vitamin d3. the results demonstrate that induction of hl-60 differentiation is associated with decreases in c-myc rna, while ther ...	1985	3856429
selective uptake of a toxic lipophilic anthracycline derivative by the low-density lipoprotein receptor pathway in cultured fibroblasts.	n-(n-retinoyl)-l-leucyldoxorubicin 14-linoleate (r11-dox), a new lipophilic derivative of doxorubicin, was synthesized and incorporated into low-density lipoprotein (ldl). the drug-ldl complex contained 100-200 drug molecules/ldl particle. when cultured normal human fibroblasts were incubated with 125i-ldl-incorporated drug, there was a perfect correlation between the cellular uptake plus degradation of 125i-ldl and the cellular drug accumulation. the presence of excess native ldl inhibited the ...	1985	3856679

mechanism of sbcb-suppression of the recbc-deficiency in postreplication repair in uv-irradiated escherichia coli k-12.	the mechanism by which an sbcb mutation suppresses the deficiency in postreplication repair shown by recb recc mutants of escherichia coli was studied. the presence of an sbcb mutation in uvra recb recc cells increased their resistance to uv radiation. this enhanced resistance was not due to a suppression of the minor deficiency in the repair of dna daughter-strand gaps or to an inhibition of the production of dna double-strand breaks in uv-irradiated uvra recb recc cells; rather, the presence o ...	1985	3911022
[effect of r plasmids on the growth characteristics of shigella sonnei and escherichia coli].	revealing of growth characteristics in plasmid and plasmid-free strains was studied with the use of two different hosts: e. coli 15-3 and sh. sonnei 11-941 containing conjugative r plasmids differing in the set of the resistance markers. it was shown that the r plasmids had no noticeable effect on the period of the lag phase and the time of the microbial cell generation. it was also shown that the number of the viable cells in separate cultures of the plasmid-free strain of sh. sonnei 11-941 and ...	1985	3911872
rapid microimmunodiffusion method with species-specific antiserum raised to purified antigen for identification of vibrio vulnificus.	an antigen common to vibrio vulnificus strains, designated vva, was purified by ammonium sulfate precipitation, gel filtration, ion-exchange column chromatography, and preparative gel electrophoresis. the molecular weight of vva was 64,000 when estimated by gel filtration and 40,000 when measured by denaturing polyacrylamide gel electrophoresis. antiserum prepared against purified vva (anti-vva serum) did not agglutinate whole cells of v. vulnificus. therefore, vva was considered a possible inte ...	1985	3918072
demonstration of a common antigen in sonicated cells for identification of vibrio vulnificus serotypes.	ouchterlony immunodiffusion of sonicated vibrio vulnificus cells illustrated a single major precipitation line with antiserum prepared from whole cells of the same species. antigenic analysis by two-dimensional immunoelectrophoresis verified the presence of a single dominant precipitation line. tandem two-dimensional immunoelectrophoretic analyses of v. vulnificus antigens from various strains revealed one fused precipitation line of identity. no fused precipitation lines were seen with other vi ...	1985	3918076

pressure- and temperature-dependent adhesion of pseudomonas aeruginosa to hep-2 cells.	pseudomonas aeruginosa bacteria adhere to human epitheloid (hep-2) cells in culture. under normal atmospheric conditions (1 ata), this adhesion increased significantly when the temperature rose from 22 to 37 degrees c. under hyperbaric atmosphere (= air, 7 ata) conditions, a similar, significant enhancement of bacterial adhesion to the cells was noted when the temperature rose. if the temperature was kept stable at 22 or 37 degrees c and the pressure was increased from 1 to 7 ata, a pressure-ind ...	1985	3925713
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 ...	1985	3931686
de novo expression of t cell markers on theileria parva-transformed lymphoblasts in cattle.	we describe monoclonal antibodies that detect two new membrane antigens on bovine t cells. one molecule is only expressed on activated t cells and has a m.w. of 100,000. the other antigen is a glycoprotein that is precipitated as two bands of m.w. 150,000 and 158,000 and is expressed on a subpopulation of t cells and all myeloid cells. we show that when bovine lymphocytes are transformed by the protozoan parasite theileria parva, both antigens become expressed on the cell surface. the infected c ...	1985	3934278
catalase enhances damage to dna by bleomycin-iron(ii): the role of hydroxyl radicals.	bleomycin degrades dna under aerobic conditions when a ferrous salt is added. this reaction is enhanced by catalase and certain hydroxyl radical scavengers but inhibited by the addition of hydrogen peroxide. a ferricbleomycin complex is, however, stimulated by addition of hydrogen peroxide. these findings suggest that catalase removes hydrogen peroxide and in so doing prevents loss of ferrous ions and formation of hydroxyl radicals (oh.) by a fenton-type reaction. it further suggests that oh. ra ...	1985	2409975

benzodiazepines enhance the muscimol-dependent activation of phospholipase a2 in glioma c6 cells.	glioma c6 cells were incubated with [14c]arachidonate to label membrane phospholipids. muscimol, a selective gamma-aminobutyric acid a receptor agonist, but not (-)-baclofen, a selective gamma-aminobutyric acid b receptor agonist, stimulates [14c]arachidonate release from c6 cells as a result of hydrolysis of a small pool of phosphatidylcholine and phosphatidylethanolamine by phospholipase a2. this release is facilitated by diazepam and a number of other benzodiazepines such as flunitrazepam, me ...	1985	2857784
immunochemical recognition of oxytocin by antiserum to l-prolyl-leucyl-glycine amide.	antisera were raised in rabbits against pro-leu-gly-nh2 (plg)-bovine thyroglobulin conjugates. specificity of the antisera towards oxytocin was evaluated by a radioimmunoassay as well as by immunohistochemical procedures on hypothalamic tissue and hormone bound to sepharose beads. it was concluded that immunization with plg can raise antisera that are specific to oxytocin.	1985	2859563
lymphatic transport of sodium cefoxitin in the presence of sodium 5-methoxysalicylate after injection into rat rectal connective tissue, femoral muscle and femoral vein.	lymphatic uptake of sodium cefoxitin after injection into rectal connective tissue was greater than after injection into the femoral muscle of rats. coadministration with sodium 5-methoxysalicylate enhanced lymphatic drug uptake at both sites. this enhancement may be an indirect result of 5-methoxysalicylate's suppression of vascular permeation of the cefoxitin. an adjuvant-induced increase in lymphatic fluid flow may also be partially involved in the enhancement of cefoxitin lymphatic transport ...	1985	2863362
[physiological and pharmacologic studies of the adrenal medulla by the measurement of plasma catecholamine levels].	the new techniques for the assay of the plasma catecholamines: noradrenaline, dopamine and, most importantly, adrenaline, because of their sensitivity and precision, have provided new information about the physiology and the pharmacology of the adrenal medulla in animals and in man. the most effective of these new techniques are the radioenzymatic techniques. the activation of the adrenal medulla in the dog or the rat appears to be frequency-dependent by maintaining a fixed concentration ratio i ...	1985	2863423
hypotensive effects after topical and intra-arterial administration of alpha-adrenergic agonists in isolated perfused rabbit eyes.	the influence of nonselective and selective alpha-adrenergic agonists on intraocular pressure (iop) was studied in isolated arterially perfused rabbit eyes. drugs were given intra-arterially or topically. with either route of administration, no initial hypertensive phase was observed after l-epinephrine, l-norepinephrine, l-phenylephrine (alpha 1), or methoxamine (alpha 1), but there was an immediate ocular hypotensive effect. the alpha 2-agonist b-ht 920 caused a nonsignificant 1 mm hg fall in ...	1985	2866480
neural and pavlovian influences on immunity.	the traditional view that the nervous and immune systems are functionally independent (aside from general stress effects and autoimmune disorders of the nervous system) is being challenged by a new view that the nervous system regulates the activity of the immune system. if this is true, it should be possible to change the activity of the immune system by means of pavlovian conditioning, just as it is possible to condition other physiological events influenced by the autonomic nervous system or ...	1985	2866484
restriction nuclease digestions driven to completion by escherichia coli rna polymerase and t4 gene 32 protein.	restriction enzyme digestions of large scale dna preparations often do not go to completion. this is due to product inhibition by the newly generated ends of the digested dna. the addition of exogenous proteins that bind tightly to the free ends of dna or to single-stranded dna will relieve this inhibition. we show that a considerable savings on restriction nucleases can be attained by the addition of rna polymerase or t4 gene 32 protein in stoichiometric amounts to the newly produced dna ends.	1985	2981211
herpes simplex virus and cytomegalovirus infections in burned patients.	herpesvirus infections are commonly seen in immunosuppressed patients and may account for considerable morbidity and some mortality. we prospectively studied 52 patients with severe burn injuries in order to determine the prevalence of viral infections in this group of patients. serologic testing was done each week to diagnose primary and reactivation infections. twenty-seven of 52 patients (52%) became infected with either herpes simplex virus (hsv) or cytomegalovirus (cmv) or both. hsv infecti ...	1985	2981325
conditioned taste aversion suppresses induction of delayed-type hypersensitivity immune reactions.	conditioned taste aversion was induced in mice by pairing saccharin drinking with an intraperitoneal injection of lithium chloride, a toxic but nonimmunosuppressive drug. conditioned mice showed not only suppressed saccharin drinking but also a 75% reduction in the induction of delayed-type hypersensitivity immune responses to low doses of sheep erythrocytes. this effect was observed with doses of lithium chloride which had no effect of their own on immune functions. in addition, a reduction in ...	1985	2987987

receptors for epidermal growth factor in the rat uterus.	uterine membranes contain high affinity [dissociation constant (kd) = 0.36 nm], saturable binding sites for [125i]iodo-epidermal growth factor (egf). the binding of [125i] iodo-egf is specific since it is abolished by excess unlabeled egf but not by excess unlabeled insulin, fibroblast growth factor, or multiplication-stimulating activity. incubation of [125i] iodo-egf with uterine membranes, followed by chemical cross-linking with disuccinimidyl suberate and detergent extraction reveals a major ...	1985	2988913
the biologic significance of the mixed lymphocyte kidney culture in humans.	the mixed lymphocyte kidney culture (mlkc) in humans has been studied in normal and abnormal clinical conditions. human renal cortical cells were extracted by collagenase treatment from the kidneys of "normal" heart-beating cadaver organ donors (n = 13), patients with end-stage renal disease (esrd) at pretransplant bilateral nephrectomy and splenectomy (n = 13), and from irreversibly rejected renal allografts at the time of graft nephrectomy (n = 5). proliferation of peripheral blood t lymphocyt ...	1985	2996186
evaluation of a photolabile derivative of 1,25-dihydroxyvitamin d3 as a photoaffinity probe for 1,25-dihydroxyvitamin-d3 receptor in chick intestinal cytosol.	we evaluated the viability of 1 alpha, 25-dihydroxyvitamin d3-3 beta-[n-(4-azido-2-nitrophenyl)glycinate] (1,25-(oh)2-d3-ang), an analog of 1 alpha, 25-dihydroxyvitamin d3 (1,25-(oh)2-d3) as a photoaffinity probe for 1,25-(oh)2-d3 receptor in chick intestinal cytosol. a competitive-binding assay revealed that chick intestinal cytosolic 1,25-(oh)2- d3 receptor bound to 1,25-(oh)2-d3-ang approximately 20-times less effectively than it did to 1,25-(oh)2-d3. irradiation of 1,25-(oh)2-d3- ang in the ...	1985	2998355
effect of pyrimidinone treatment on lethal and immunosuppressive murine cytomegalovirus infection.	the 2-amino-5-halo-pyrimidinones, which are potent interferon inducers and antiviral agents, were found to be protective against lethal cytomegalovirus (cmv) challenge in weanling or neonatal mice when administered before virus challenge. this protection was dependent upon the dosage of pyrimidinone administered. weanling mice infected with a sublethal challenge of cmv exhibited moderate to severe immunosuppression as measured by reduced splenic cell blastogenic responses in vitro to the mitogen ...	1985	3000290
dimethylthiourea consumption reflects h2o2 concentrations and severity of acute lung injury.	even though dimethylthiourea (dmtu) effectively scavenges o2 metabolites in vitro, it is often unclear if scavenging of o2 metabolites is the mechanism by which dmtu decreases tissue injury in biological models. since dmtu not only scavenges o2 metabolites but is also consumed in a dose-response manner following reaction with hydrogen peroxide (h2o2) in vitro, we wondered whether dmtu would also be consumed by o2 metabolites in biological systems and if dmtu consumption would then reflect o2 met ...	1985	3001019
non-immune igg f(ab')2 binding to group c and g streptococci is mediated by structures on gamma chains.	the present investigation was designed to determine whether the heavy or the light immunoglobulin chain is involved in the non-immune binding of igg f(ab')2 fragments to specific surface receptors on human group c and g streptococci. purified human polyclonal igg was mildly reduced with dithiothreitol and alkylated with iodoacetamide. light (l) and heavy (h) chains were separated. intact igg and purified l and h chains of polyclonal immunoglobulin g were tested in an inhibition assay for non-imm ...	1985	3156400

differential initiation of translation of a single estrogen receptor mrna could explain some estradiol resistance cases.	cell response to steroid stimulation is generally acknowledged to be mediated by an intracellular protein known as a receptor. response intensity is related to the affinity of the receptor and to the number of sites occupied by its specific ligand. although verified in the majority of experimental and clinical studies, certain phenomena of steroid hormone resistance would seem to challenge this assertion. application of gene molecular biology to determine the action mechanisms of steroid hormone ...	1986	1306521
different effects of the ionophore a-23187 and d-glucose on 45ca2+ fluxes in isolated islets of ob/ob-mice.	fluxes of 45ca2+ were studied in beta-cell rich islets of non-inbred ob/ob-mice, using lacl3 to wash out extra-cellular and superficially bound 45ca2+. the ionophore a-23187 (10 microm) increased the 45ca2+ uptake in islets both at 3 and 20 mm d-glucose, the effect being more pronounced after 10 min than after 120 min of incubation. in incubations for 120 min, 20 mm d-glucose induced a higher uptake of 45ca2+ than did a-23187. the ionophore enhanced the unidirectional efflux of 45ca2+ from prelo ...	1986	362823
dose-related effects of synthetic human beta-endorphin and naloxone on fed gastrointestinal motility.	in humans, plasma beta-endorphin levels rise during application of acute stressful stimuli (vertigo, cold pain, and transcutaneous electrical stimulation) that induce gut motor disturbances. whereas it is possible that circulating beta-endorphin participates in the mediation of these central effects on gut motility, its role cannot be established solely on the basis of changes in plasma levels. therefore, we designed the present study to investigate 1) the dose-related effects of intravenous syn ...	1986	2942039
structure-activity relationships of sex steroid analogs determined in vitro in a thyroid hormone-responsive membrane ca2+-atpase model.	physiological concentrations of l-t4 were found previously to stimulate ca2+-atpase activity in vitro in reticulocyte membranes from female rabbits and to inhibit this enzyme in reticulocyte membranes from males. in these previous studies, preincubation of intact cells or ghosts with testosterone (5 x 10(-11) m) converted female-source reticulocyte membranes to male-type responsiveness to thyroid hormone (inhibition of ca2+-atpase activity). preincubation of reticulocyte membranes with 17 beta-e ...	1986	2946570
