systemic therapy for metastatic breast cancer.the data reviewed in this conference suggest that initial therapeutic decisions for patients with metastic breast cancer be based on the presence or absence of an estrogen receptor in the tumor. patients with estrogen receptor in their original primary breast cancer or in a subsequent metastitic lesion are candidates for hormonal manipulation, whereas patients lacking estrogen receptor in their tumor are treated for their metastic disease with nonhormonal chemotherapy. nonhormonal therapy usuall ...1977835932
susceptibility of propionibacterium acnes to seventeen antibiotics.the in vitro susceptibility of 96 isolates of propionibacterium acnes to 17 antibiotics was determined by utilizing an agar dilution technique. with the exception of the aminoglycosides, these organisms are susceptible to virtually all of the commonly used antimicrobial agents.1977836012
isolation and identification of fecal bacteria from adult swine.an examination of the fecal microflora of adult swine was made with regard to the efficiency of several roll tube media in enumeration and recovery of anaerobes, the effects of medium constituents on recovery, and the isolation and identification of the predominant kinds of bacteria. total number of organisms by microscopic bacterial counts varied among fecal samples from 4.48 x 10(10) to 7.40 x 10(10) bacteria/g (wet weight). comparison of different nonselective roll tube media indicated that a ...1977836025
intravenous corynebacterium parvum: an adjunct to chemotherapy for resistant advanced ovarian cancer.this is a prelimianry report of an effort to treat women with advanced (stage iii and iv) ovarian cancer who had progressive disease in spite of previous surgery, chemotherapy and/or radiation by a program of reductive surgery, intensive immune stimulation and combination chemotherapy. an initial laparotomy was done where possible to reduce tumor burden, and then all patients were given intravenous corynebacterium parvum (c.p.) in escalating doses over a 10- to 14-day period. cyclic chemotherapy ...1977837334
in vitro and in vivo cytotoxicity of adriamycin and daunomycin for murine macrophages.in virto exposure of murine lymphoma cells to adriamycin and daunomycin (dm) for 24 hr resulted in comparable cytotoxicity as assessed by viable cell counts and inhibition of dna synthesis. the spontaneous dna synthesis of spleen lymphocytes in vitro was also equally affected by the two agents. however, when the in vitro effects of the two drugs on macrophage monolayers were investigated, dm was found to be at least four times more toxic than am. in vivo-administered dm was more suppressive than ...1977837378
chemoattractant properties of corynebacterium parvum and pyran copolymer for human monocytes and neutrophils.both pyran copolymer and the burroughs-wellcome vaccine of corynebacterium parvum were able to elicit a migratory response by human neutrophils or monocytes when incubated with serum. however, in the absence of serum, neither agent elicited such a response. the generation of the chemotactic factor by pyran was dependent on heat-labile components in the serum, while suggested involvement of the complement sequence. conversely, the migratory response of c. parvum in heated serum was equivalent to ...1977839571
the influence of nonspecific immunotherapy on the course of murine melanoma.bcg, corynebacterium parvum, vitamin a, and levamisole were continuously administered to c57 bl/6 mice bearing b16 melanoma prior to, with following tumor implantation as well as before and coincident with surgical excision of the implanted tumor. only the group given levamisole prophylactically for 8 weeks before tumor inplantation showed a significant difference from control mice but a tenfold increase in dosage in this drug did not exert a comparable effect.1977839793
corynebacterium parvum and cyclophosphamide as combination treatment for a murine mammary adenocarcinoma.weekly i.p. injections of killed corynebacterium parvum and of cyclophosphamide (given on different days) strongly inhibited growth of a transplantable murine mammary adenocarcinoma. a significant portion (40 to 80%) of animals could be made tumor free by means of combined therapy. no tumor-free survivors were obtained with c. parvum alone, and tumor-free mice were obtained with cyclophosphamide alone only at the expense of a high incidence of deaths due to drug toxicity. no evidence of tumor re ...1977844041
[susceptibility to thiamphenicol and chloramphenicol of anaerobic bacteria (author's transl)].the in vitro susceptibility to thiamphenicol and chloramphenicol of 272 anaerobes, most of which were recent clinical isolated, was determined by broth dilution tests, with chloramphenicol, 133 anaerobic gram-negative non-sporing rods (48 bacteroides fragilis, 13 b. thetaiotaomicron, 14 b. oralis, 16 sphaerophorus varius etc.) had mic values of 0.03 through 16 microng/ml. very similar results (mic, 0.06-16 microng/ml) were obtained with thiamphenicol. in concentrations of 4 microng/ml or less ch ...1977848218
anaerobic bacteria in otitis media.anaerobic bacteria, peptostrepotococcus intermedius and propionibacterium acnes, were found in mixed culture specimens from four to ten tested cases of chronic secretory otitis media. these anaerobic bacteria were in a mixed infection flora with aerobic bacteria most often staphylococcus epidermidis and cornybacterium sp. which do not fit any established species. the findings of anaerobic bacteria in otitis media is consistent with the sporadic report of the involvement of anaerobic bacteria in ...1977848830

combined treatment with anaerobic corynebacterium liquefaciens and chemotherapeutics against solid tumor in mice.the combined effect of anticancer agents (mitomycin-c, cyclophosphamide, or 5-fluorouracil) and anaerobic corynebacterium liquefaciens on subcutaneously induced solid ehrlich carcinoma in mice was examined. mitomycin-c and cyclophosphamide were given intraperitoneally on day 7 after inoculation of tumor cells. 5-fluorouracil was administered intraperitoneally for 7 consecutive days from day 9 to 15. c. liquefaciens was given in two ways, intraperitoneally and intratumorally. its injections were ...1977863171
an analysis of the factors allowing promotion (rather than inhibition) of tumour growth by corynebacterium parvum.the following factors were found to determine whether c. parvum (cp) treatment promoted rather than inhibited the growth of methylcholanthrene-induced fibrosarcoma cells injected into cba mice. (1) the dose of tumour cells. promotion occurred only with low doses, around the td50. (2) the route of injection of cp. greater promotion was caused by intravenous (iv) than by subcutaneous (sc) administration. addition of irradiated tumour cells to sc cp resulted in tumour inhibition. (3) the dose of cp ...1977863546
effect of corynebacterium parvum, methanol-extraction residue of bcg, and levamisole on macrophage random migration, chemotaxis, and pinocytosis.three parameters of macrophage function: random migration, chemotaxis, and pinocytosis, were studied in the guinea pig after administration of corynebacterium parvum, methanol-extraction residue of bcg, and levamisole (lms), a synthetic anthelmintic. macrophage migration studies were performed with a modified boyden chamber. pinocytosis was assessed by the uptake of colloidal 198au. after ip administration, each of the three immunostimulators induced an increase in macrophage chemotactic respons ...1977864753
the distribution and persistence in vivo of corynebacterium parvum in relation to its antitumor activity.killed corynebacterium parvum was labeled with fluorescein isothiocyanate or 125i, and both preparations were shown to retain lymphoreticular stimulatory and antitumor activity. large amounts of c. parvum injected i.v. were found in the liver, spleen, and lungs with less in bone marrow and lymph nodes. apart from a rapid loss from the lungs within 24 hr, the persistence of killed c. parvum was striking, and some intact bacteria were still detectable in the liver and spleen at 15 days. (by contra ...1977870181
antibody to corynebacterium parvum in normal human and animal sera.using a microtiter bacterial agglutination test, we have estimated antibodies to corynebacterium parvum in "normal" human and "normal" and immune animal sera. widely differing levels of c. parvum antibodies were found in the normal human sera. the median titer for all 310 human sera was 1:128, whereas that for the 1- to 17-year and 18- to 50-year subgroups was 1:64 and 1:512, respectively. antibody titers in the various animal species were generally much lower.1977870426
comparative effect of anaerobic coryneforms on a murine melanoma.ten strains of anaerobic corynebacteria were compared in their effect on survival of c57bl/6 mice, bearing subcutaneously inoculated b16 melanomas. the corynebacterial suspensions were injected intralesionally twice weekly for five injections. significant permanent tumor regression was not obtained. significant prolongation of survival was observed in mice treated with seven of the corynebacterial strains.1977872039
cell-mediated immunity and serum blocking factors in cancer patients during chemotherapy and immunotherapy.the leukocyte adherence inhibition test was used to monitor tumor-specific cell-mediated immunity in 15 patients who had a variety of malignant tumors and were undergoing chemotherapy alone or in combination with immunotherapy by corynebacterium parvum. a rapid and prolonged loss of cell-mediated immunity in blood leukocytes was observed after treatment in all but one of the patients studied. abolition of reactivity was due to the lack of production of the soluble lymphokine-like factor affectin ...1977872076
separation and characterization of epithelial cells from prostates and prostatic carcinomas: a review.our investigation of normal, hyperplastic, and neoplastic prostatic tissue during the past 2 1/2 years has produced several findings which have been published or accepted for publication. (a) cells from hamster prostates with intense histochemically demonstrable acid phosphatase activity (hdap) after fixation with formaldehyde which we believe to be epithelial cells can be obtained in 97.2% +/- 0.8% purity by velocity sedimentation in a previously described isokinetic density gradient; (b) simil ...1977872127

host immunological mechanisms in the resistance of mice to leptospiral infections.several serovars of leptospira virulent for hamsters and guinea pigs caused acute lethal leptospirosis in mice immunosuppressed with cyclophosphamide. neither bcg vaccine nor corynebacterium parvum suspension influenced the course of leptospiral infection in either immunosuppressed or normal balb/c mice. nude athymic mice produced anti-leptospiral antibody and were therefore resistant to infection with leptospires. nude mice were made susceptible with cyclophosphamide but were immune if they had ...1977885617
an adenylate cyclase of brain reflects propensity for breast cancer in mice.high propensity for breast cancer in mice was associated with low dopamine-stimulated adenylate cyclase activity in the brain, low spontaneous motorization, and low motor responses to injections of the catecholamine precursor, l-dopa.1977887942
intravascular coagulation resulting from intravenous injection of c. parvum in mice.in mice, i.v. c. parvum induces intravascular coagulation. this is a prolonged reaction lasting up to 7 days. it results in thrombosis in hepatic vessels with consequent hepatic necrosis, and thrombosis in pulmonary and splenic vessels. this may be important in the assessment of the tumour-inhibitory activity of c. parvum.1977889682
mechanism of the anti-tumour effect of glucans and fructosans: a comparison with c. parvum.the anti-tumour activity induced by glucans (lentinan, yeast cell walls, pseudonigeran, dextran, deae-dextran and dextran sulphate) and fructosans (levan and carboxymethyl-levan) was compared with the activity of c. parvum. the following effects on tumour systems in cba mice were assayed: (a) adjuvant activity on the immune response against tumour-specific transplantation antigens (tsta) with a methylcholanthrene-induced fibrosarcoma; (b) cytostatic activity of peritoneal macrophages against rad ...1977889684
comparative study of corynebacterium parvum and corynebacterium liquefaciens on antitumor activity against sarcoma-180.corynebacterium parvum and corynebacterium liquefaciens were comparatively examined for their antitumor activity against sarcoma-180 in ddy mice. in the case of ascitic form, significant antitumor effect was observed when c. parvum was administered on days -4 and -2 or day -2. as for solid form, maximal effect was obtained when c. parvum was administered on day 0. on the other hand, c. liquefaciens exhibited maximal antitumor activity against sarcoma-180, both in ascitic and solid forms, when it ...1977892298
effect of immunomodulators on effector cells involved in antibody-dependent cellular cytotoxicity: brief communication.the effect of four immunomodulators (bcg, corynebacterium parvum, pyran copolymer, and levamisole) on the cellular arm of antibody-dependent cellular cytotoxicity (adcc) was investigated in mice with 51cr-labeled chicken erythrocytes employed as targets. all these drugs, except levamisole, stimulated the effector cells of adcc in the spleen, but the kinetics of their effect differed. stimulation of the effector cells of adcc peaked on day 15 after injection of bcg and c. parvum and on day 7 afte ...1977894742
combined radiotherapy and corynebacterium parvum treatment of a murine fibrosarcoma.a single dose of corynebacterium parvum (cp) at 70 microgram, 175 microgram or 350 microgram was effective in suppressing the growth of a subcutaneous fibrosarcoma and occasionally in inducing complete regression and in prolonging the survival time of c3h/hej tumor-bearing mice. a single exposure of x rays at 2,000 rads induced some complete regression, but a higher number of complete regressions was induced by combined x-ray and cp treatment. in the combined x-ray and cp treatment, cp given on ...1977897175

expression of a new cell surface antigen on activated murine macrophages.a macrophage cell-surface antigen associated with pyran and corynebacterium parvum-activated macrophages and p388d1 cells but not detectable on normal or glycogen and thioglycollate-elicited murine macrophages has been described. the antigen was demonstrated both by complement-mediated cytotoxicity and immunofluorescence, using an appropriately absorbed rabbit antiserum to p388d1. this antiserum should enable the characterization of activated macrophage cell populations on an individual cell bas ...1977925608
a study on the characterization of corynebacterium acnes.forty-nine strains of anaerobic gram-positive rods were used in a systematic study of their biochemical and physiological reactions and morphological characteristics and were also subjected to gas chromatographic analyses in an effort to classify them as strains of corynebacterium acnes (c. acnes). the strains were isolated both from lesions in acne vulgaris and from normal skin. according to their biochemical and physiological characters, these 49 strains were divided into six subgroups (subgro ...197715461349
paradoxical effects of immunopotentiators on tumors and tumor viruses.growth of tumors was inhibited or enhanced in mice by a synthetic (pyran) or a biologic (corynebacterium parvum) immunopotentiator. marked inhibition of leukemogenesis induced by friend leukemia virus was produced by prophylactic intraperitoneal treatment with pyran, while intravenous treatment with pyran (in the same dose and regimen) significantly enhanced growth of tumor virus. paradoxical effects were also seen with the biologic immunopotentiator c. parvum in solid tumor systems. treatment w ...1976932503
study of the mechanism of corynebacterium parvum anti-tumour activity. i. protective effect on the growth of two syngeneic tumours.the protective effect of c. parvum against two different tumours - a lymphosarcoma and a mammary carcinoma - has been demonstrated. in the case of lymphosarcoma, a significant protective effect was obtained when both c. parvum and tumor cells were injected iv. in contrast in c3h mice the best protection was obtained when both c. parvum and mammary carcinoma cells were injected ip. thus both c. parvum and tumour cells must be inoculated by the same route which, however, varies for different tumou ...1976946965
observations following corynebacterium parvum administration to patients with advanced malignancy. a phase i study.there has been increasing interest regarding the use of corynebacterium parvum (cp) with other modalities in the management of primary cancer. due to the paucity of specific information available relative to cp toxicity, a phase i study was carried out in patients with advanced disease. the purpose of the investigation was not to evaluate the effect of cp on tumor growth. from 273 injections of cp in 40 patients it was observed that following intravenous (i.v.) infusion of cp: a) a febrile respo ...1976947509
regression of a hamster melanoma with intralesional corynebacterium granulosum.the present study was undertaken to compare the antitumour effects of intralesionally administered corynebacterium granulosum, corynebacterium parvum, bcg and saline on a hamster melanoma. forty-eight golden hamsters were inoculated subcutaneously with forthers melanotic melanoma no. 1. twenty-four animals bore palpable tumours which were excised. no non-excised group animal showed primary tumour regression. in the excised group, the tumours generally recurred at the excision site in the c. parv ...1976949459
treatment of rat fibrosarcoma by radiotherapy plus immune adjuvant.combined radiotherapy and nonspecific adjuvant c. parvum or piromen treatment of rat tumors show improvement over radiotherapy alone. the most effective protocol, resulting in complete remission in 6 of 6 rats was obtained with c. parvum given i.p. in three doses 1 day prior to tumor x-irradiation of three doses of 1500 r each given on days 1, 4, and 8. animals receiving the same dose schedule without adjuvant had only partial regression of their tumor. without adjuvant, increasing the dose to 6 ...1976949523
radiation therapy and corynebacterium parvum in the treatment of murine tumors.the relative effectiveness of local irradiation alone or combined with corynebacterium parvum (c parvum) treatment has been investigated employing four tumors: a mammary carcinoma (mca) (nonimmunogenic), a fibrosarcoma (moderately strongly immunogenic), and two squamous cell carcinomas (scc-2 being weakly and scc-4 being very weakly or nonimmunogenic). c parvum treatment was started when the isotransplanted tumor growing in the mouse leg was 5 mm in diameter and the local irradiation was adminis ...1976949676

comparison of the potentiation of specific tumor immunity in mice by corynebacterium parvum or bcg.two independent studies have compared killed c. parvum (cp) vaccine with viable bcg (pasteur) and bcg (glaxo) vaccines, respectively, for potentiation of antitumor immunity when injected with irradiated tumor cells into b6d2f1 and cba-t6t6 mice. both studies concurred that, for a given number of irradiated tumor cells, larger amounts (dry weight equivalent) of bcg than cp were required to produce similar degrees of tumor immunity. evidence also showed that stronger and more protracted immunity w ...1976978769
biotyping and serotyping of propionibacterium acnes strains isolated from different diagnostic materials.fifty strains of propionibacterium acnes, five strains with the previous designation corynebacterium parvum and three strains of propionibacterium avidum were agglutinated by bacto-corynebacterium acnes 554 antiserum (difco); it was not possible to isolate any strain reacting only with 605 antiserum. only one strain of c. parvum reacted with both sera. 48 (88 per cent) out of 54 strains (p. acnes and c. parvum) belonged to voss' group i and 25 (47 per cent) belonged to pulverer's biotype a. str ...1976983535
antimicrobiol susceptibility of propinibacterium acnes and related microbial species.the minimal inhibitory concentrations of 32 antimicrobial agents were established for 73 strains of propionibacterium acnes and four related species (p. granulosum, p. avidum, corynebacterium minutissimum, and c. parvum). most strains showed good susceptibility to those agents usually considered active against gram-positive organisms. with the exception of c. minutissimum, the strains tested revealed more or less identical susceptibility ranges. the lowest minimal inhibitory concentrations were ...1976984781
the characteristics of binding of corynebacterium parvum to glass-adherent mouse peritoneal exudate cells.corynebacterium parvum, strain 10390, whole organisms were shown to bind to the surface of glass-adherent mouse peritoneal exudate cells in vitro. an hcl extract and a lipid extract of the organism were both capable of inhibiting this binding. the attachment of organisms was not affected by trypsin treatment of the cells, indicating that the plasma membrane receptor is not cell-bound antibody in nature. the binding was inhibited by various sugars, most of which are major components of the cell w ...1976991461
effects of corynebacterium parvum treatment and toxoplasma gondii infection on macrophage-mediated cytostasis of tumour target cells.injection of mice with corynebacterium parvum or living or killed toxoplasma gondii was studied to determine the efficacy of these treatments in activating peritoneal macrophages to inhibit the uptake of [3h]tdr (cytostasis) by tumour target cells in vitro. in the presence of activated macrophages from mice treated i.p. with a wide dose range of either c. parvum or living toxoplasma, cytostasis was usually greater than 99%. this population of activated macrophages was transient in c. parvum-trea ...1976992714
experimental cancer immunotherapy: comparison of tumor rejection if f344 rats given live mycobacterium bovis (strain bcg) and killed corynebacterium parvum.f344 rats received grafts of syngeneic 13762 mammary adenocarcinoma cells previously admixed with either living bcg of killed corynebacterium parvum administered sc or intradermally (id). animals given id transplants of tumor cells admixed with either bcg or killed c. parvum exhibited tumor growth for an average of 10 days, then regression in size and rejection of the tumor nodules. lesions were found in rats given sc transplants of tumor cells admixed with the killed microorganism for an averag ...1976994209
antitumor activity of killed corynebacterium parvum suspensions in a murine mammary adenocarcinoma cad2) system.we studied the antitumor activity of killed corynebacterium parvum on the cad2 mammary adenocarcinoma in dba/2 mice. intratumor treatment had little or no effect on subcutaneous tumor growth. admixture of tumor cells with c. parvum before inoculation completely suppressed tumor growth. no tumor transplantation immunity was detected in mice inoculated with admixtures of c. parvum and tumor cells, but tumors were enhanced under certain circumstances. growth of a tumor inoculated sc or iv was consi ...1976994219
complement activation in vivo in cancer patients receiving c. parvum immunotherapy.serum complement levels were assayed in 26 patients with disseminated cancer, who received immunotherapy with infusion of c. parvum. complement activation, indicated by the consumption of c3 or c4 or both, was found in 46% of the patients. serum samples showed direct correlation between decreased c3 and conversion of c3 proactivator, whereas such conversion did not occur when c4 alone was decreased. it is concluded that the bypass (properdin) pathway was activated in patients in whom c3 consumpt ...1976999783
decreased liver and lung drug-metabolizing activity in mice treated with corynebacterium parvum.injections of killed suspensions of corynebacterium parvum (i.p.) in young male mice were followed by time- and dose-dependent decreases in the drug-metabolizing activity of liver microsomes and lung homogenates. in vitro assays with model substrates [aminopyrine, aniline, p-nitroanisole, and benzo(a)pyrene] were used to quantitate drug-metabolizing activity. it is likely that such decreases in mixed function oxidases activity will act to significantly alter the pharmacokinetics of concurrently ...19761000491
further observations on the inhibition of tumor growth by corynebacterium parvum with cyclophosphamide. iii. effect of c. parvum on cyclophosphamide metabolism.results of investigations employing [14c]cyclophosphamide (cy) demonstrated that even though total plasma radioactivity was similar in female c3heb/fej mice treated either with cy alone or corynebacterium parvum and cy, the proportion of total activity due to nonmetabolized cy was greater when c. parvum was used. these findings indicated that the antitumor effect of c. parvum may not have been entirely due to its immunopotentiating properties but may also have been related to its effect on the m ...19761003505
further observations on the inhibition of tumor growth by corynebacterium parvum with cyclophosphamide.the cytotoxic macrophage was further characterized as an important effector cell in the inhibition of tumor growth. when we administered rifampin (a semisynthetic antibiotic that interferes with macrophage function but not viability) with corynebacterium parvum and/or cyclophosphamide to tumor-bearing c3heb/fej female mice, the tumor growth-inhibitory effects of the c. parvum were reduced. moreover, when bone marrow cells from those animals were cultured, we found a marked decrease in the cytoto ...19761003514
effects of corynebacterium parvum alone and in combination with adriamycin in experimental tumor systems.corynebacterium parvum (c. parvum) was used in antitumor tests against four murine tumor models in b6d2f1 mice. the c. parvum was effective at all doses and schedules tested against p388 leukemia, b16 melanoma, and lewis lung carcinoma but was ineffective against l1210 leukemia. combination immunochemotherapy of p388 leukemia and lewis lung carcinoma with c. parvum and adriamycin was better than either regimen alone in increasing the lifespan of mice with tumors. the results show that the effect ...19761009517

serum lysozyme as a marker of host resistance. i. production by macrophages resident in rat sarcomata.with progressive growth of syngeneic sarcomata in rats there was a rise in serum levels of lysozyme which correlated with their immunogenicity and their macrophage content. by an examination of lymph/blood differences in normal and in tumour bearing rats and of the production of lysozyme by cells obtained from the tumours and maintained in vitro, it is apparent that the macrophages resident in a tumour mass make a massive contribution to the elevation in serum lysozyme concentrations. tumour cel ...1976766806

immunology and lung cancer.carcinoma of the lung is the number one cancer killer in the united states. the overall cure rate is about 10%, and although resection is the best treatment available, five-year survival following operation is only 25%. recent studies have shown that patients with lung cancer are immunosuppressed but that pulmonary tumors do contain tumor-associated antigens. studies of other human tumors indicate that immunotherapy can augment tumor immunity and can be an effective surgical adjuvant. this commu ...1976769714
immunogenicity of a rat leukaemia of spontaneous origin (sal).the sal rat leukaemia, which resembles acute myeloblastic leukaemia, appeared initially to be non-immunogenic since resistance to an i.p. challenge with as few as 100 cells could not be obtained using stimulation of the res or by immunization with sal cells exposed to x-rays, nitrogen mustard, iodoacetate or glutaraldehyde. however, immunization with sal cells exposed to low doses of mitomycin-c slowed the growth of the challenge inoculum. cells treated with high doses of mitomycin-c did not imm ...1976769814
nonspecific immunotherapy by corynebacterium parvum: phase i toxicity study in 12 patients with advanced cancer.corynebacterium parvum, a non-specific immunopotentiator, was administered intravenously to 12 patients with advanced cancer at 2, 3, and 4 mg/m2 dose levels in combination with radiation therapy. one dose of c. parvum was given every 7 days for a total of 4 doses in 21 days. symptoms and signs developed by these patients for a period of 3 to 6 hours during and shortly after the i.v. infusion of the first dose of c. parvum were moderately severe in nine patients and mild in three patients. for t ...1976769937
failure of corynebacterium parvum presensitization to modify the antitumor effects of systemic and local therapeutic injections of c. parvum in mice.the therapeutic effects of iv and intralesional injection of corynebacterium parvum against mastocytoma p815 in mice, presentized and showing marked delayed hypersensitivity to c. parvum, were no different from those in unimmunized controls.1976815560
[effect of corynebacterium parvum on murine cultured bone marrow cells].the administration of corynebacterium parvum (c. parvum) stimulates in the mouse the bone marrow colony forming cell compartment in two stages. the first stage reaches pic values one day after two consecutive injections and the second, more important stage, reaches a pic at the 9th day which lasts over 27 days. there is no evidence that this effect is related to the liberation of csf.1976816561
effect of cytochalasin b on the adhesion of mouse peritoneal macrophages.the adhesion of normal mouse macrophages to glass surfaces was reduced by nontoxic levels (1-50 mug/ml) of cytochalasin b in combination with a centrifugal force (1,000-8,000 g). macrophages nonspecifically activated by corynebacterium acnes were also detached by this treatment, but less effectively. the effects of cytochalasin b treatment on these cells were shown to be reversible. after detachment, the cells reattached to glass, appeared morphologically normal, and behaved like untreated cells ...1976816801
responsiveness of senescent mice to the antitumor properties of corynebacterium parvum.the antitumor properties of corynebacterium parvum have been studied in young (3- to 8-month-old) and aged 18 or more months old) balb/c mice given s.c., i.m., i.p., or i.v. transplants of the highly malignant, weakly immunogenic line 1 lung carcinoma, and in aged (25- to 33-month-old) balb/c mice bearing primary mammary tumors. these aged balb/c mice were shown to be less immunoresponsive than their younger counterparts, and this, in combination with nonimmunological factors, made them more sen ...19761247995

antitumor activity of corynebacterium parvum extracts.extracts of corynebacterium parvum produced by mild hydrolysis of the whole organisms had antitumor activity if given iv 1 day before iv administration of fibrosarcoma cells or if given ip or sc in admixture with these cells. a lipid component seemed responsible for these effects. unlike whole bacteria, they had little immunotherapeutic activity if given 3 days after sc tumor implantation unless absorbed onto latex. however, organisms treated with acid did not have any immunotherapeutic effect i ...19761255777
further observations on the inhibition of tumor growth by corynebacterium parvum with cyclophosphamide. ii. effect of cortisone acetate.studies from this laboratory have demonstrated that the administration of cyclophosphamide (cy) and corynebacterium parvum (cp) over a prolonged time to c3h mice with established measurable tumors resulted in complete arrest of tumor growth as well as partial and complete regressions in many instances. a study of the effect of two different doses of cortisone acetate (ca), administered two or five times weekly, on the tumor inhibitory properties of this chemoimmunotherapeutic regimen indicated t ...19761255788
anaerobic infections in children: a prospective study.the prevalence and significance of anaerobic infections in patients at st. louis children's hospital were studied prospectively for a one-year period. blood, selected body fluids, and aspirates obtained from abscesses or areas of cellulitis were cultured using special anaerobic collection and processing techniques. infected peritoneal fluid from patients with gastrointestinal disease yielded a large proportion of all anaerobic isolates. the types of organisms isolated were common inhabitants of ...19761256941
immunotherapy and human tumor immunology.present knowledge about the immune response to tumors in man is briefly reviewed, and the effects of cancer on immune-system functions are noted. the concepts that human tumors elicit cell-mediated immune responses to tumor antigens are re-examined and modified; for example, cell-mediated immunity may be detectable only at certain stages of tumor growth. introduction of more sensitive methods for detecting antibodies is providing additional evidence for humoral immune responses to tumor-associat ...19761259292
effect of corynebacterium parvum on the response to irradiation of a c3h fibrosarcoma.a methylcholanthrene-induced fibrosarcoma of c3h mice has been used as 5th- to 6th-generation syngeneic transplant in an investigation of the role of corynebacterium parvum as an adjuvant to the therapeutic effect of local irradiation of established tumors. the most effective route for administration of c. parvum in this tumor system was i.v., and the greatest effect of the c. parvum-mediated tumor graft rejection was observed for tumor growing intracutaneously or s.c. an intermediate level of e ...19761260756
