plasma protein synthesis in experimental cancer compared to paraneoplastic conditions, including monokine administration.during tumor growth, there are characteristic alterations in the concentration and synthesis of various plasma proteins. the purpose of this study was to evaluate whether these changes are unique to a tumor-bearing state, or rather, they represent a generalized response to a paraneoplastic state mediated by the release of monokines or protein-calorie malnutrition. plasma protein synthesis and concentrations in mice bearing a transplantable fibrosarcoma were compared to animals receiving either a ...19873117356
incomplete surgery, local immunostimulation, and recurrence of some tumour types in dogs and cats.histologically confirmed inadequate treatment resulted in a lower than expected recurrence percentage in dogs with haemangiopericytoma (38%) and mastocytoma (30%). clinical suspicion of inadequate tumour treatment did not always correlate with the histologically assessed inadequacy, nor with the appearance of local recurrence. local recurrence did not seem to be correlated with histological grade of malignancy and tumour size. local injection of c. parvum vaccine did not result in a lower percen ...19873118558
induction of interleukin 1 secretion and of tumoricidal activity in macrophages are not closely related phenomena.rat bone marrow-derived mononuclear phagocytes (bmm phi), induced to differentiate in vitro and homogeneous with respect to the cell lineage, were interacted with various macrophage-activating agents. the effect of these agents on the secretion of interleukin 1 (il 1) activity and on the development of tumoricidal capacity was comparatively assessed. the findings show that il 1 secretion is considerably enhanced by macrophage-activating factor and by recombinant interferon-gamma but remained una ...19873119353
a study on the adhesive properties of cor. diphtheriae and cor. parvum in the direct haemagglutination reaction.the adhesive properties of one cor. parvum and two cor. diphtheriae strains were investigated by means of the direct haemagglutination reaction (har). using a specifically developed har procedure, it was proved beyond doubt that the studied corynebacteria possess adhesive properties apparently associated with the presence of pili (fimbrias) on their surfaces. in addition, a correlation was found between the agglutinating activity of bacteria and the conditions of culture growth. based on the rep ...19873119703

cytopathogenic protein in filtrates from cultures of propionibacterium acnes isolated from patients with kawasaki disease.propionibacterium acnes may have a role in kawasaki disease. filtrates from cultures of p acnes isolated from cervical lymph node biopsy specimens and blood samples from patients with kawasaki disease were studied and compared with samples from control subjects. after inoculation of human embryo liver cells with filtrates from the patients a cytopathogenic effect and vacuolation were seen. a specific cytopathogenic substance was found in only the filtrates of cultures from patients with kawasaki ...19873120957
modulation of beta-galactosidase activity in peritoneal macrophages from c57b1 mice after exposure to proprionibacterium acnes.peritoneal macrophages (pm luminal diameter) from untreated c57b1 mice contain high levels of beta-galactosidase (beta-gal) and these pm luminal diameter are heterogeneous in their expression of this enzyme. intraperitoneal (i.p.) injection of saline caused a transient depression in the level of enzyme activity in the pm luminal diameter whereas i.p. injection of proprionibacterium acnes (p. acnes) gave rise to a marked decrease of beta-gal activity in these cells. this reduction in enzymatic ac ...19873122521
hepatic reticuloendothelial system activation in autoimmune mice: differences between (nzb x nzw)f1 and mrl-lpr/lpr strains.5'-nucleotidase (5'n) activity and ia expression of hepatic nonparenchymal cells (npcs) of the autoimmune (nzb x nzw)f1 and mrl-lpr/lpr and nonautoimmune c3h/fej, dba/2j, and a/j strains were assayed to determine endogenous activation of the hepatic reticuloendothelial system (res). pretreatment of the nonautoimmune strains with corynebacterium parvum resulted in decreases in fc receptor expressor and 5'n and an increase in ia expression of npcs. endogenous hepatic res activation, as measured by ...19873030589
the immunological activities of components isolated from corynebacterium parvum in mice injected with polyoma tumor cells.the inhibition of polyoma tumor in cba mice after immunization with different fractions of corynebacterium parvum was investigated. treatment with 200 micrograms of polysaccharide from culture filtrate before s.c. inoculation 2 x 10(6) of tumor cells induced antitumor effect in mice. treatment with lower doses (1 microgram or 20 micrograms) after transplantation of tumor cells was not effective. injection of lipopolysaccharide from escherichia coli abolished a positive response on inhibition of ...19873031518
encephalomyocarditis (emc) virus-induced diabetes mellitus prevented by corynebacterium parvum in mice.corynebacterium parvum prevented the development of encephalomyocarditis virus-induced diabetes in mice, when it was given 3-14 days before the virus infection. this treatment inhibited virus replication in the pancreas of the infected mice at an early stage of the infection.19873032672
methadone vs morphine: comparison of their effect on phagocytic functions.a comparison of the effects of methadone and morphine on phagocytic physiology was carried out in mice, using a number of tests, to estimate the risk of using methadone in maintenance protocols for opiates addicts. results indicate that methadone, like morphine, reduces (a) r.e.s. activity and (b) pmn superoxide anion production, while unlike morphine it (a) does not produce haematologic changes, (b) does not exacerbate c. albicans infections, (c) does not inhibit phagocytosis and killing by mur ...19873034811
antigen-specific suppression of the in vitro cytotoxic response by a soluble factor produced by corynebacterium parvum-induced allospecific suppressor cells.the adjuvant corynebacterium parvum, when administered intravenously during an ongoing alloimmunization, induces alloantigen-specific splenic suppressor cells which inhibit primary and secondary in vitro sensitizations. we have previously shown that these cells produce a soluble suppressor factor in culture. we now further characterize this factor and its mechanism of action. release of this suppressive factor is dependent upon specific restimulation of the splenic suppressor cell with the sensi ...19872949854
uptake of protoporphyrin and violet light photodestruction of propionibacterium acnes.the uptake of protoporphyrin ix by propionibacterium acnes in suspension has been studied by fluorescence spectroscopy. protoporphyrin, after it was injected into a cell suspension, was firstly bound to receptors on the cell surface and in this state protoporphyrin was non-fluorescent. subsequently, probably as a result of lateral diffusion in the cell wall, these protoporphyrin-receptor complexes formed dimers. the final step in the overall uptake process of protoporphyrin by the cells from the ...19872953128

acne vulgaris and malignancy.seventy patients with lymphomas and leukaemias were interviewed. details of past acne vulgaris were recorded and a clinical examination performed. a history of acne was less common in the patients than in matched controls. in addition, fewer patients had received treatment prescribed by a medical practitioner for their acne than had the controls. examination revealed fewer patients with acne. these results suggest a reduced incidence of acne or its more severe forms in patients who have develope ...19882974720
granulocyte activating factor released from propionibacterium acnes. a possible mediator of inflammation in acne vulgaris.incubation of propionibacterium acnes but not of propionibacterium granulosum or propionibacterium avidum (for 30 min at 37 degrees c in physiological saline) released a soluble factor that produced enhanced chemiluminescence response of human granulocytes as well as increased chemotactic motility of these cells. sephadex g-25 filtration of the granulocyte activating factor (gaf) revealed its low molecular weight and apparent peptide character. thus, gaf may be a stimulus for inflammation in acn ...19882975904
bone marrow derived macrophages have polyamine and ectoenzyme phenotypes distinct from resident macrophages.several prototype macrophage (mo) populations were compared for differences in ectoenzyme phenotype and polyamine content. resident peritoneal mo and corynebacterium parvum (cp)-activated peritoneal mo expressed unique ectoenzyme phenotypes, while bone marrow derived mo (bmdmo), obtained from stem cells after 7 days in culture with colony stimulating factor, and thioglycollate (tg)-elicited peritoneal mo exhibited a similar ectoenzyme phenotype. all of the mo populations, however, differed in po ...19882835568
effect of macrophage activation on resistance of mouse peritoneal macrophages to infection with herpes simplex virus types 1 and 2.to define the effect of heterogeneity of murine peritoneal macrophages (m phi) on intrinsic resistance to herpes simplex virus (hsv) infection, several m phi populations were characterized for their response to infection with hsv type 1 (hsv-1) and hsv-2. steady-state resident m phi (res m phi) were compared in parallel with m phi activated with corynebacterium parvum (now designated propionibacterium acnes) (cp m phi) and thioglycollate-elicited inflammatory m phi (tg m phi). res m phi were com ...19882841412
effect of endotoxin on release of reactive oxygen intermediates by rat hepatic macrophages.reactive oxygen intermediates released by activated hepatic macrophages have been implicated in the pathogenesis of a rat model of liver injury induced by sequential administration of corynebacterium parvum and endotoxin. in this model, c. parvum causes extensive infiltration of the liver with activated macrophages, but severe liver injury occurs only after subsequent exposure to endotoxin. we have therefore investigated the effects of endotoxin on the release of reactive oxygen intermediates by ...19882846404
influence of immunomodulatory agents on bovine humoral and cellular immune responses to parenteral inoculation with bovine rotavirus vaccines.sodium diethyldithiocarbamate (dtc), mycobacterium cell wall extract (mcwe, regressin), killed corynebacterium parvum (c. parvum, immunoregulin) and muramyldipeptide (mdp) were each combined with purified, live bovine rotavirus and inoculated into 3 month-old holstein-friesian calves in order to examine their ability to potentiate specific humoral and cellular immune responses. the vaccinated calves were boosted twice at 3 and 6 weeks after initial vaccine inoculation. the rotavirus was administ ...19882847397
[in vitro activity of an ofloxacin-metronidazole combination against anaerobic bacteria. kinetics of the action of metronidazole against bacteroides fragilis].the activity of metronidazole combined with ofloxacin was investigated by the checkerboard method in liquid medium against 60 obligate anaerobes. the bacteriostatic effect of the combination was assessed by calculating the fic index. two metronidazole resistant strains of propionibacterium acnes (mic greater than 32 mg/l) were inhibited by 0.125 mg/l of this former antibiotic in presence of an ofloxacin concentration equal to half the value of the mic. on the 58 other anaerobic strains, the comb ...19883043345

protective effects of a leukotriene inhibitor in an experimental massive hepatic cell necrosis model.when heat-killed propionibacterium acnes was intravenously injected into mice and seven days later, a small amount of gram-negative lipopolysaccharide was also intravenously injected, most of them died of massive hepatic cell necrosis. however, when azelastine hydrochloride, a leukotriene antagonist chemically known as 1(2h)-phthalazinone, 4-[(4-chlorophenyl)methyl]-2-(hexahydro-1-methyl-1h-azepine-4-yl)-, monohydrochloride, or aa861, 2-(12-hydroxydodeca-5, 10-diynyl)-3,5,6-trimethyl-1, 4-benzoq ...19883136049
alteration of non-specific resistance to infection with listeria monocytogenes.the experimental infection of murine hosts with listeria monocytogenes is often used as a model for cell-mediated immunity. however, the natural immunity or non-specific resistance to listeriosis can be influenced by the parasite itself and also by a wide array of endogenous and exogenous host factors. the most important host factor in inbred mouse strains is their genetically determined susceptibility or resistance to listeria monocytogenes. secondly, the age of the mice is crucial for the outc ...19883138182
effect of psk, a protein-bound polysaccharide from coriolus versicolor, on drug-metabolizing enzymes in sarcoma-180 bearing and normal mice.the effects of psk and propionibacterium acnes (anaerobic corynebacterium) on hepatic drug-metabolizing enzymes were studied using sarcoma-180 bearing and non-tumor bearing mice. psk had no influence on aminopyrine n-demethylase and aniline hydroxylase activities, cytochrome p-450 concentration in hepatic microsomes, and the reductase activity of cytochrome c in normal mice. the content of cytochrome p-450 was not significantly reduced in s-180 bearing mice. on the other hand, p. acnes administr ...19883139576

correction of defective tumoricidal activity of macrophages from a/j mice by liposomal immunomodulators.the ability of liposomal immunomodulators to restore abnormal macrophage tumoricidal activity has been studied. macrophages from a/j mice have impaired responses in vitro to macrophage activating factor, gamma-interferon, n-acetylmuramyl-l-alanyl-d-isoglutamine (mdp) or lipopolysaccharide when compared with macrophages from normoresponsive c57bl/6j mice. liposomes containing a lipophilic muramyl dipeptide mdp-glyceroyl dipalmitate, macrophage activating factor or gamma-interferon restored tumori ...19883360595
neutrophil involvement in effects of diethylstilbestrol and strontium 89 on macrophage activation by propionibacterium acnes.we have recently demonstrated that diethylstilbestrol (des) significantly suppresses macrophage (m phi) activation by propionibacterium acnes. because the initial activation of m phi by p. acnes appears to involve the close interaction of the killed bacteria with inflammatory neutrophils (pmn) and resident m phi in the peritoneal cavity, we investigated whether the des inhibition of m phi activation was associated with inhibition of the pmn response. our data demonstrate that treatment of mice w ...19883366512
susceptibility of anaerobic bacteria to antimicrobial agents.the antimicrobial susceptibility of 1,117 clinical isolates of anaerobic bacteria was determined by the agar dilution technique. metronidazole was the most active agent; only propionibacterium acnes and actinomyces sp. isolates were resistant. clindamycin and chloramphenical were the next most effective agents. beta-lactam antibiotics, with the exception of penicillin, were active against most anaerobes other than the bacteroides fragilis group. at a breakpoint of 8 mg/l, 25% of fusobacterium sp ...19883374973
liver injury model in mice for immunopharmacological study.experimental liver injury was produced in mice by the immunological technique. the utility of these models as an immunopharmacological method was investigated. the first model was produced by the injection of anti-basic liver protein (blp) rabbit antibody into dba/2 mice that had been previously immunized with rabbit igg. the second liver injury was caused by injection of anti-liver specific protein (lsp) rabbit antibody into dba/2 mice. the third model was produced by the injection of bacterial ...19883379835
the ability of inflammatory bronchoalveolar leucocyte populations elicited with microbes or mineral dust to injure alveolar epithelial cells and degrade extracellular matrix in vitro.inflammatory cells are recruited to the parenchyma of the lung in a range of conditions where they are considered to have the ability to exert damaging effects on elements of the alveolus. the injurious effects of rat bronchoalveolar-derived inflammatory cells on an alveolar type ii epithelial cell line were therefore assessed. inflammatory populations produced by intratracheal injection of corynebacterium parvum or quartz caused non-lethal detachment injury to the epithelial cells on co-culture ...19883390385

comparison of corynebacterium parvum and bordetella pertussis with freund's complete adjuvant as immunopotentiators for beta-human chorionic gonadotropin linked to an atoxic fragment of tetanus toxin.corynebacterium parvum and bordetella pertussis were compared with freund's complete adjuvant (fca) for their abilities to potentiate the immune response to haptenic beta-human chorionic gonadotropin covalently coupled to an atoxic 54,000-molecular-weight fragment of tetanus toxin (beta-hcg-ttii). the ability of each adjuvant to enhance production of antibodies to hcg in rabbits was measured by 125i-hcg radioimmunoassay. at sera dilutions of 1:10,000, analysis of variance for the 8-week postimmu ...19892475138
analysis of propionibacterium acnes-induced non-specific immunity to trypanosoma brucei in mice.mice treated with dead propionibacterium acnes (previously called corynebacterium parvum), up to 30 days before infection with any of three strains of trypanosoma brucei, were more able to limit the level of first-wave parasitaemia than untreated controls. reduced parasitaemia was not due to enhanced phagocytosis of input parasites and was associated with a dramatic reduction in the proportion of multiplying t. brucei in the blood of treated as compared to control mice. for 4 days after p. acnes ...19892476711
characterization of interferons produced by peripheral blood mononuclear cells from healthy subjects in response to corynebacterium parvum or poly i: poly c.the biological significance of acid labile interferon alpha is presently unknown. we examined the putative production of acid labile interferon in vitro from human peripheral blood mononuclear cells induced with corynebacterium parvum or poly i: poly c. both agents induced up to 1200 iu/ml interferon, and the interferon was 80 to 90% acid labile. the interferons were typed by antibody neutralization of their antiviral activity. contrary to previous reports, c. parvum induced predominantly interf ...19892483976
modulation of macrophage functions by corynebacterium parvum preparations.corynebacterium parvum has been used as an anti-tumor agent in both animal experiments and clinical trials; nevertheless it is not well established the mechanism of action, since both t-dependent and t-independent ways of action have been proposed. on the other hand, mononuclear phagocytic system activation cannot be ruled out in the immunomodulation carried out by c. parvum. in the attempt to better understand the effects of c. parvum on macrophage functions, experiments were carried out on tum ...19892491287
protective effect of sk&f 86002, a novel dual inhibitor of arachidonic acid metabolism, in murine models of endotoxin shock: inhibition of tumor necrosis factor as a possible mechanism of action.the effect of a new, structurally novel, dual inhibitor of arachidonic acid (aa) metabolism, sk&f 86002, was studied in two murine models of endotoxin shock. the first model was the injection of c57bl/6 mice with lipopolysaccharide (lps) in combination with d-galactosamine (d-gal), which resulted in death within 6-48 hr. treatment of these mice with sk&f 86002 (100 mg/kg, p.o.) 30 min to 2 hr prior to the administration of d-gal and lps protected the animals from mortality. protection was also p ...19892492908
