| rational therapy for acne vulgaris: an update on topical treatment. | acne vulgaris is a disorder of sebaceous follicles that usually begins at the time of the sharp increase in androgen production that occurs in adolescence. this disease is most prevalent among teenagers, but it does occur in patients in their twenties and thirties. three major areas of pathophysiology have been identified in acne: hyperkeratinization and obstruction of sebaceous follicles, resulting from abnormal desquamation of follicular epithelium; an androgen-stimulated increase in the produ ... | 1986 | 2945846 |
| the in vitro antimicrobial effect of azelaic acid. | various strains of cutaneous micro-organisms were tested in vitro for their survival rates in 0.5 mol/l (8.4% w/v) azelaic acid solution. all bacterial strains exhibited large reductions in viability (at least 40-fold) over a 24 h test period, but little response was noted with pityrosporum ovale. the bactericidal effect of azelaic acid was reduced considerably in the presence of nutrients. minimum inhibitory concentrations (mics) and minimum bactericidal (or fungicidal) concentrations (mbcs) we ... | 1986 | 2947607 |
| photodestruction of endogenous porphyrins in relation to cellular inactivation of propionibacterium acnes. | during growth of propionibacterium acnes on eagles medium protoporphyrin was accumulated inside the cells and coproporphyrin, both as a free base as metalcontaining, outside the cells. the photochemical processes in the endogenous porphyrins were studied by fluorescence spectroscopy during continuous irradiation of propionibacterium acnes in suspension. the irradiation caused initially an increase in the content of protoporphyrin in the cells in comparison to that which had been accumulated duri ... | 1986 | 2948330 |
| comparing 2.5%, 5%, and 10% benzoyl peroxide on inflammatory acne vulgaris. | a 2.5% formulation of benzoyl peroxide was compared with its vehicle, and with a 5% and a 10% proprietary benzoyl peroxide gel preparation in three double-blind studies involving 153 patients with mild to moderately severe acne vulgaris. the 2.5% benzoyl peroxide formulation was more effective than its vehicle and equivalent to the 5% and 10% concentrations in reducing the number of inflammatory lesions (papules and pustules). desquamation, erythema, and symptoms of burning with the 2.5% gel wer ... | 1986 | 2948929 |
| in vitro and in vivo evaluation of a-56268 (te-031), a new macrolide. | the in vitro and in vivo antibacterial activity of a-56268 (te-031), the 6-o-methyl derivative of erythromycin, was compared with those of erythromycin and other reference drugs. a-56268 had the same spectrum of antibacterial activity as erythromycin. a-56268 was generally 1 log2 dilution more potent or equal to erythromycin against all organisms except haemophilus influenzae and propionibacterium acnes, for which a-56268 was 1 log2 dilution and 3 log2 dilutions, respectively, less potent. the m ... | 1986 | 2949695 |

| [microbial pathogenesis of whipple's disease]. | in a case of whipple's disease with electron microscopic demonstration of rod-shaped bacteria we could isolate propionibacterium acnes (former name: corynebacterium anaerobium), actinomyces, and lactobacillus from duodenal biopsies by the aid of modern anaerobic culture technique. simultaneously we found a dysbiosis (increase of anaerobic coca and anaerobes) in du odenal juice. after antibiotic treatment propionibacterium and lactobacillus disappeared and an other type of dysbiosis (appearance o ... | 1986 | 2424711 |
| aspartate-assisted immune stimulation: its importance in antitumor and antiviral protection. | immune stimulators such as corynebacterium parvum (cp) are useful for antitumoral and antiviral therapy. however, the immune trigger cannot be reactivated without adversely affecting the disease. we have tried to amplify the results yielded by a single injection of cp by using either interleukin-2 (il2) or aspartate salts (asp). in the present report, we show that il2 has no detectable clinical effect. in contrast, the addition of an asp salt increases the antiviral and antitumoral protection af ... | 1986 | 2426209 |

| interferon-mediated protection of b16 melanoma cells from cytotoxicity by activated macrophages. | corynebacterium parvum-activated macrophages (m phi), purified by adherence, were cytotoxic for b16 melanoma cells maintained in vitro. pretreatment of the melanoma cells for 18 hr with interferon-alpha/beta or -gamma (ifn-alpha/beta or -gamma) caused a reduced susceptibility of the b16 cells to m phi-mediated cytotoxicity. the ifn-induced protective effect of b16 cells from cytotoxic m phi was found to be dose dependent. in addition, ifn-gamma was more protective than ifn-alpha/beta. the protec ... | 1986 | 2427205 |
| effects of diethylstilbestrol on propionibacterium acnes immunomodulation: inhibition of macrophage activation and antitumor activity. | exposure of mice to diethylstilbestrol (des) inhibited propionibacterium acnes-induced antitumor activity in vivo against the b16f10 subcutaneous tumor. the inhibitory effect was associated with inhibition by des of the characteristic p. acnes induced splenomegaly and changes in splenic and peritoneal macrophages (m phi) cell populations. the characteristic p. acnes induced reductions in m phi alkaline phosphodiesterase i (apd) ectoenzyme activity and in total rna synthesis, proposed biochemical ... | 1986 | 2430037 |
| natural immunity to grafts of fld-3 erythroleukemia cells by irradiated mice. | mice were irradiated and infused with balb/c friend virus-induced fld-3 erythroleukemia cells. growth of the cells was estimated by measuring splenic incorporation of 5-iodo-2'-deoxyuridine-125i 5 days after cell transfer. balb/cj and c3h mice were 'poor responders' in that fld-3 cells grew well in their spleens, while mice of other strains were 'good responders', resisting the growth of fld-3 cells. no h-2 or fv genetic locus was associated with resistance. athymic nude mice and mice depleted o ... | 1986 | 2430178 |

| the effect of oral zinc administration on sebum free fatty acids in acne vulgaris. | free fatty acids in sebum arise from lipolytic action of bacterial lipases. we have demonstrated an inhibitory effect of zinc on the lipase of the three propionibacterium species found in human pilosebaceous follicles. we were also able to show a small corresponding fall in the free fatty acid content of skin surface lipid in vivo in acne patients treated with zinc, though this failed to reach statistical significance. | 1986 | 2430400 |
| corynebacterium parvum in malignant pleural effusion. a randomized prospective study. | in a randomized trial, pleurodesis was attempted with corynebacterium parvum in one group and bleomycin in another. patients with malignant pleural effusion which required repeated drainage were treated with instillation of one of these agents after complete drainage of the pleural effusion. there were 32 patients who could be evaluated. sixty-five per cent of the patients treated with c. parvum had no recurrence after one treatment and another 29% after two treatments. in the bleomycin group, t ... | 1986 | 2430825 |
| interferon production in propionibacterium acnes treated mice. | interferonogenic properties of propionibacterium acnes (pa) was studied in vivo and in vitro using cba, balb/c and 129aoboy strains of mice. ifn was induced only in cba strain after i.v. pa injection. balb/c and 129aoboy mice did not produce ifn. in the sera of cba mice, obtained after i.p. injection of pa, interferon was not found. however, spleen cells of these mice produced ifn beginning from the 3rd day after injection. this interferon response lasted until the 10th week. furthermore, in viv ... | 1986 | 2431669 |
| prolongation of survival of mice bearing the eb and esb lymphoma by treatment with interferon inducers alone or in combination with corynebacterium parvum. | the objective of this study was to evaluate if pretreatment with corynebacterium parvum (c. parvum) augments the effects of interferon (ifn) inducers on survival of dba/2 mice transplanted with two syngeneic lymphoma variants, the low metastatic eb and the high metastatic esb tumor. the involvement of ifn in the treatment effects was investigated. as inducers of ifn-alpha/beta newcastle disease virus (ndv), polyinosinic-polycytidylic acid (polyi:polyc), and 10-carboxymethyl-9-acridanone (cma) we ... | 1986 | 2431778 |
| tests on protection against viral diseases. | despite many attempts to find reliable in vitro criteria for the efficacy of biological response modifiers--brms (immunomodulators, paramunity inducers) animal challenge models are still the only way to demonstrate the totality of interlocking defense mechanisms. challenge models with mouse pathogenic viruses provide an excellent possibility to study protective effects of brms against acute or chronic forms of viral diseases. for comparative studies two completely different virus challenge model ... | 1986 | 2431829 |

| splenocytes from tumor-bearing corynebacterium parvum treated mice maintain interleukin-2 and -3 activity. | systemic and local administration of the bacterium corynebacterium parvum (more accurately known as propionibacterium acnes) is reported to exert antitumor action via activated macrophages or short-lived cytotoxic t lymphocytes (ctl), respectively. this study examined the effect of c. parvum treatment on resulting in vitro interleukin levels, which are components in the sequence of events leading to the development of effective ctl. c. parvum administration prevented palpable fibrosarcoma develo ... | 1986 | 2939948 |
| suppression of murine nk activity induced by corynebacterium parvum: further characterization and abrogation of suppressor cells. | formalin-killed corynebacterium parvum (cp), given at a dose of 0.4-0.7 mg/mouse iv or ip, induced suppressor cells for nk activity in b6c3f1 mice. the suppressor cells belong to at least two different populations, plastic adherent and nonadherent, and were not depleted by antibodies specific for thy-1.2, iak, or nk-1.2 surface markers. administration of p-i:c, an interferon-inducer, to animals 18 h before the assay did not affect the suppressor activity. hypotonic shock treatment of splenocytes ... | 1986 | 2935247 |
| tumor-specific suppressor t-cells which inhibit the in vitro generation of cytolytic t-cells from immune and early tumor-bearing host spleens. | spleen cells from dba/2 mice, after immunization with syngeneic p815 mastocytoma cells and corynebacterium parvum, respond to p815 in vitro with a brisk, secondary-type generation of cytotoxic cells. this cytotoxicity is mediated by antigen-specific t-lymphocytes and correlates with resistance to in vivo challenge. this model confirms the observations of previous investigators made in semisyngeneic hosts using an in vivo transfer model. spleen cells from "early" tumor-bearing hosts (tbhs), 7-12 ... | 1986 | 2936451 |
| [proof of the effectiveness of a clotrimazole cream paste in acne vulgaris]. | the efficacy of clotrimazol cream paste containing a penetration enhancer in the treatment of acne vulgaris was objectified by investigating the sebum composition. following treatment over three and six weeks, the ratio of triglyceride to free fatty acid significantly increased, which indicated an effective reduction of the lipase activity of propionibacterium acnes within the sebaceous follicle. | 1986 | 2938349 |
| protease production by microorganisms associated with reproductive tract infection. | factors influencing pathogenicity of various microbes found in the female lower genital tract remain incompletely understood. protease production by cervico/vaginal microorganisms may alter or inactivate a variety of proteins important in host defense and structural-functional integrity including collagen-containing chorioamniotic membranes and uterine cervix. host tissues may be made more susceptible to other organisms' virulence factors by protease-producing members of genital tract local flor ... | 1986 | 3004213 |
| deficient ifn alpha production in hairy cell leukemia. | since the application of low doses of ifn-alpha is necessary to maintain remissions in hairy cell leukemia (hcl) it is of interest whether peripheral blood mononuclear cells (mnc) of hcl patients can be induced in vitro to produce ifn-alpha. 9 patients suffering from advanced hcl were included in the study. the diagnoses were confirmed by characteristic findings in peripheral blood and bone marrow biopsies. for ifn treatment we initially used natural ifn-alpha (bioferon) and switched later to re ... | 1986 | 3006840 |
| distribution of intrapleural and intravenous corynebacterium parvum in humans; 99mtc-, and 131i-labeled bacteria. | the distribution of corynebacterium parvum labeled with 131iodine or 99mtechnetium was studied in 17 patients with bronchogenic carcinoma. the labeled bacteria were given intravenously or intrapleurally and monitored by whole-body gamma tracking and samples of blood and urine. even though the rate of physical decay is quite different for 131iodine and 99mtechnetium, the tracking time of labeled bacteria was limited to 24 h after injection for both radioactive isotopes. technetium labeling was pr ... | 1986 | 3011262 |
| protection of mice against herpes simplex virus infection by a lactobacillus casei preparation (lc 9018) in combination with inactivated viral antigen. | heat-killed lactobacillus casei yit 9018 (lc 9018) cells enhanced the resistance to herpes simplex virus type 1 (hsv-1) in adult mice, but not significantly. the protection of mice against hsv-1 infection and the production of neutralizing antibodies were significantly enhanced by the administration of lc 9018 in combination with inactivated hsv-1 antigen. the optimal enhancement of resistance was seen in mice 14 days after the simultaneous administration of these substances. the resistance to h ... | 1986 | 3012292 |
| possible polyclonal b cell activation in mucocutaneous lymph node syndrome. | immunoserological studies on polyclonal b cell activation were carried out on 39 patients with mucocutaneous lymph node syndrome (mcls) and in age-matched healthy individuals. the incidence of anti-mite, p. acnes (kato) and eb virus antibodies, recently proposed as aetiological agents by some investigators, was increased in the patient group. serum immunoglobulin (ig) m level and igm-anti-dinitrophenyl (dnp) antibodies, which are considered to be parameters of polyclonal b cell activation, were ... | 1986 | 3015624 |
| relationship of success in classical immunotherapy to the relative immunorejective strength of the tumor. | six tumors of varying immunorejective strengths were used to compare the response of their isogenic hosts to standardized regimens of immunoprophylaxis and immunotherapy. the tumors were generated spontaneously or induced chemically [with 9,10-dimethyl-1,2-benzanthracene (cas: 57-97-6)], virally (with murine leukemia virus), or radiogenically (with strontium-90). the hosts were c57bl/6j or balb/cbyj mice. immunoprophylaxis and immunotherapy were performed with isogenic irradiated tumor cells, wi ... | 1986 | 3020300 |
| the role of superoxide anion and lysosomal enzymes in anti-listerial activity of elicited peritoneal macrophages. | the in vitro effect of superoxide anion and lysosomal enzyme activity on the killing of listeria monocytogenes egd (listeria) by peritoneal macrophages (pm) was investigated. generation of superoxide anion by pm stimulated with phorbol myristate acetate (pma) was significantly increased by intraperitoneal injection of lactobacillus casei yit 9018 (lc9018) or corynebacterium parvum (cp), but not by injection of peptone. however, superoxide anion generation by lc9018-elicited pm stimulated with li ... | 1986 | 3020680 |
| biological activity of pityrosporum. ii. antitumor and immune stimulating effect of pityrosporum in mice. | the antitumor activity of pityrosporum (p. orbiculare, p. ovale, p. pachydermatis, and pityrosporum sp.) on ehrlich ascites carcinomas (eacs) implanted into outbred icr mice was studied. pityrosporum significantly prolonged the survival of mice, regardless of the administration mode. in the case of p. orbiculare, the maximum survival time was 32.3 days on the mean and was obtained by injection ip of 1 mg (dry weight) p. orbiculare for 7 consecutive days following inoculation of the tumor cells. ... | 1986 | 3022057 |
| alveolar lymphocyte proliferation induced by propionibacterium acnes in sarcoidosis patients. | the proliferation of lymphocytes induced by propionibacterium acnes (p. acnes) was measured by the in vitro incorporation of 3h-thymidine. the mean response rate of alveolar lymphocytes obtained by bronchoalveolar lavage was 2.23 +/- 0.89 in nine untreated sarcoidosis patients, 0.85 +/- 0.17 in five sarcoidosis patients given corticosteroids and 0.78 +/- 0.29 in 11 controls. the proliferation was significantly enhanced in the untreated patients compared to both the treated patients (p less than ... | 1986 | 3024453 |
| the effect of kupffer cell stimulation or depression on the development of liver metastases in the rat. | tumour cells from a squamous carcinoma (approximately 2.5 x 10(5)) were injected intraportally into a syngeneic strain of rats to produce liver metastases 14 days later. kupffer cells were stimulated by corynebacterium parvum (7 mg or 1 mg i.v.) and zymosan (10 mg intraportally). kupffer cell activity was depressed by the administration of silica, gadolinium chloride or human red cells. the animals in each group were sacrificed at 14 days, the livers removed and the number of visible surface met ... | 1986 | 3024833 |

| macrophage membrane proteins: possible role in the regulation of priming for enhanced respiratory burst activity. | brief exposure of macrophages to the proteolytic enzymes papain, elastase, or trypsin primed them for enhanced production of superoxide anion (o2-) in response to stimulation by phorbol myristate acetate (pma). priming by trypsin was achieved at 0 degree c, at which temperature trypsin functions as a protease but is not internalized, supporting the concept that protease priming depends on modification of the plasma membrane. analysis of external membrane proteins after radioiodination of intact ... | 1986 | 3026655 |
| macrophage activation in rat models of inflammation and arthritis: determination of markers of stages of activation. | disease-associated alterations in macrophage functions were assessed by investigating the stages of activation of peritoneal macrophages obtained from adjuvant-induced arthritic rats. the stages of activation were established by defining several functional parameters in macrophages obtained from normal, sterile-irritant injected and propionibacterium acnes injected animals. peritoneal macrophages taken from arthritic rats 17 days post adjuvant injection displayed parameters characteristic of act ... | 1986 | 3026656 |
| calcium-dependent and -independent tumoricidal activities of polymorphonuclear leukocytes induced by a linear beta-1,3-d-glucan and phorbol myristate acetate in mice. | some antitumor immunomodulators, such as a linear beta-1,3-d-glucan from alcaligenes faecalis var. myxogenes ifo 13140 (tak), induce potent tumoricidal activity of polymorphonuclear leukocytes (pmns). in the present study we investigated the role of calcium on the tumoricidal activity of pmns induced by immunomodulators, especially tak. the calcium chelator ethylene glycol bis(beta-aminoethyl ether)-n,n,n',n'-tetraacetic acid (egta) almost completely inhibited tak-induced pmn cytotoxicity and th ... | 1986 | 3079591 |
| enhancement of hematopoietic response of mice by subcutaneous administration of lactobacillus casei. | mice that had received heat-killed lactobacillus casei (lc 9018) subcutaneously (s.c.) showed enhanced resistance to systemic (i.e., intravenous) infection with listeria monocytogenes, but the antilisterial resistance of mice was less augmented by s.c. administration of propionibacterium acnes ("corynebacterium parvum"). though there was little change in the total number of splenic leukocytes after s.c. administration of lc 9018, the monocyte-macrophage ratio increased after treatment, reaching ... | 1986 | 3082755 |
| [effects of krestin (psk) on drug-metabolizing enzymes with special reference to the activation of ft-207]. | the effects of psk on hepatic drug-metabolizing enzymes were investigated using sarcoma 180-bearing and non-tumor-bearing icr mice. psk, an immunomodulator, has been commonly used in combination with tegafur for post-operative adjuvant chemotherapy. tegafur is a typical masked compound transformed into 5-fu by the hepatic drug-metabolizing enzyme p-450. it has been reported that immunostimulants such as bcg and anaerobic corynebacterium suppress the drug metabolism. psk and propionibacterium acn ... | 1986 | 3090941 |
| modification of the antitumor action of corynebacterium parvum by stress. | social grouping and isolation of mice, in the presence of an acute stressor, were found to differentially affect the antitumor action of the immunological adjuvant corynebacterium parvum. socially grouped dba/2j mice were injected intradermally with p815 mastocytoma ascites cells. half the mice had a threshold dose of c. parvum admixed with the p815 cells. half the mice in each of those conditions were given acute, inescapable electric footshock. in a second experiment, the stressed mice were so ... | 1986 | 3092254 |
| suppression of fibroblast proliferation by activated macrophages: involvement of h2o2 and a non-prostaglandin e product of the cyclooxygenase pathway. | macrophages are considered promoters of fibroblast proliferation; however, suppression by activated macrophages may outweigh this effect. activated murine peritoneal macrophages obtained by in vivo exposure to c. parvum or by in vitro lps-activation of thioglycollate-induced macrophages, were tested for their effect on normal syngeneic dermal fibroblasts. c. parvum-activated macrophages, but not resident peritoneal macrophages suppressed fibroblast proliferation. similarly, macrophages activated ... | 1986 | 3093089 |
| the role of anti-asialo gm1 antibody-sensitive cells in the implementation of tumor-specific t cell-mediated immunity in vivo. | the present study deals with the role of cells sensitive to anti-asialo gm1 antibody treatment in t cell-mediated tumor cell eradication in vivo. rabbit anti-asialo gm1 antiserum was injected into c3h/he mice. this treatment not only resulted in almost complete abrogation of natural killer (nk) cell activity but also produced a potent inhibiting effect on the generation of activated macrophage activity induced by inoculating propionibacterium acnes (p. acnes). such an immunodepressed state laste ... | 1986 | 3093429 |
| immunomodulation with killed propionibacterium acnes in guinea pigs simultaneously vaccinated with brucella abortus strain 19. | immunomodulation with killed propionibacterium acnes was attempted in guinea pigs simultaneously vaccinated with brucella abortus strain 19. two groups, each comprised of 9 guinea pigs, were injected by different routes (s.c. and or i.v.) with 1.4 mg of p. acnes and 5 x 10(8) cfu of b. abortus, s-19, while 3 other groups each received either p. acnes, b. abortus s-19, or saline (s.c.). the antibody titers to b. abortus measured at 6, 10 and 14 weeks after vaccination indicated no significant (p ... | 1986 | 3094237 |
| randomized study of corynebacterium parvum adjuvant therapy following surgery for (stage ii) malignant melanoma. | one hundred and fifteen patients with histologically proven primary cutaneous melanoma were entered into a randomized prospective study following surgical removal of clinically obvious regional metastases. the study started in 1977 and was completed in june 1982. fifty-eight patients (10 with regional skin metastases and 48 with regional node metastases) were in the control group and 57 (15 regional skin, and 42 regional node metastases) received adjuvant c. parvum. other clinical features were ... | 1986 | 3512025 |
| effect of macrophage activation on phagocyte-plasmodium interaction. | we investigated the effect of both immune and normal sera on the binding of free plasmodium berghei by resident and activated macrophages. resident macrophages bound plasmodia to a greater extent than did activated macrophages, regardless of treatment. resident macrophages bound free plasmodia, predominantly trophozoites, in the presence of normal serum by a mechanism inhibited by n-acetylglucosamine and n-acetylmannosamine. macrophages activated through treatment with propionibacterium acnes (" ... | 1986 | 3512432 |
| lack of biological significance of in vitro brugia malayi microfilarial cytotoxicity mediated by propionibacterium acnes ("corynebacterium parvum")-and mycobacterium bovis bcg-activated macrophages. | the effect of nonspecific activation of host macrophages by propionibacterium acnes ("corynebacterium parvum") or mycobacterium bovis bcg on brugia malayi microfilariae was determined by in vitro and in vivo studies. intraperitoneal injection of c. parvum or bcg stimulated peritoneal exudate cells, which were toxic to microfilariae. microfilariae were equally susceptible to damage by c57bl/6j or balb/cj peritoneal exudate cells. furthermore, inhibitors of oxidative metabolism and arginine supple ... | 1986 | 3516877 |
| bcg, in contrast to c. parvum, does not induce increased sensitivity to the toxic effects of indomethacin in mice. | treatment of mice with killed corynebacterium parvum (also designated propionibacterium acnes, p. acnes) or bacille calmette guerin (bcg) leads to modification of several of the same host systems. however, bcg, in contrast to c. parvum, did not induce increased sensitivity to the toxic effects of indomethacin in balb/c or c57b1/6 mice. in addition, treatment of mice with bcg did not interfere with the induction of sensitivity by c. parvum. therefore c. parvum must uniquely induce changes in host ... | 1986 | 3519813 |
| therapy of stage iii (optimal) epithelial carcinoma of the ovary with melphalan or melphalan plus corynebacterium parvum (a gynecologic oncology group study). | a randomized prospective therapy trial in patients with stage iii optimal epithelial carcinoma of the ovary was accomplished by the gynecologic oncology group. therapy with melphalan or melphalan plus immuno-adjuvant, corynebacterium parvum (c. parvum), was utilized as adjuvant treatment following surgical therapy. one hundred eight-five patients were eligible for evaluation with 87 patients in the melphalan group and 98 patients in the melphalan plus c. parvum group. the comparison of the treat ... | 1986 | 3525343 |
| a sequential study of hepatic structural damage following the intravenous injection of corynebacterium parvum. | sequential histological and fine structural changes were studied in liver from 4.5 min to 21 days after a single intravenous injection of corynebacterium parvum in the rat. a previously unreported effect of the micro-organism, the formation of eosinophilic inclusion bodies within hepatocytes, was observed between 15 min and 24 h of injection. these structures were most common in periportal hepatocytes at 2 h. the structural, enzyme- and immunohistochemical features of these bodies suggest that t ... | 1986 | 3527581 |
| propionibacterium acnes cerebral botryomycosis. the role of plastic embedding in the diagnosis of grain-producing infections. | botryomycosis is a chronic infection in which bacterial colonies, or "grains," occur in purulent exudate associated with draining sinus tracts or abscess formation. this condition usually is caused by staphylococcus and streptococcus, but other organisms occasionally have been implicated. this report describes the first case of botryomycosis caused by propionibacterium acnes, a diphtheroid that has been rarely associated with opportunistic disease. in this case, plastic embedding allowed the obs ... | 1986 | 3535486 |

| augmentation of nk activity and/or macrophage-mediated cytotoxicity in the liver by biological response modifiers including human recombinant interleukin 2. | administration of several biological response modifiers (brms) to mice strongly augmented natural killer (nk) activity of leukocytes isolated from the liver. this augmentation of nk activity was induced by two synthetic molecules (mve-2 and poly iclc), by two brms of bacterial origin (formalin-fixed propionibacterium acnes: p. acnes and a streptococcal cell wall preparation designated ok-432), as well as a single injection of human recombinant interleukin-2 (hril 2). all of these brms augmented ... | 1986 | 3484675 |
| role of t-cell subsets in the destruction of established metastases of 13762a rat mammary adenocarcinoma. | the 13762a rat mammary adenocarcinoma metastasizes with high frequency to regional lymph nodes and lungs. the intratumoral injection of corynebacterium parvum on day 7 followed by primary tumor excision on day 20 significantly prolonged survival and cured 10-40% of syngeneic f344 rats. established metastases were destroyed by the treatment, and strong and specific tumor rejection immunity was induced. the purpose of the present study was to determine if t-cells were required for the c. parvum tr ... | 1986 | 3487670 |
| incidence and growth of methylcholanthrene-induced tumors in mice with altered immunological status. | balb/c mice were treated s.c. with 3-methylcholanthrene (mca), and tumor incidence and growth were followed for 9 months. immunological status of mice was altered by various treatments. thymectomized, lethally irradiated, bone marrow reconstituted mice served as t-cell deficient recipients. in order to suppress natural killer (nk)-cell/macrophage functions some mice were injected with silica particles; to enhance these functions some mice were given corynebacterium parvum (cp). silica and cp wer ... | 1986 | 3490910 |

| role of pulmonary macrophages in resistance to experimental metastasis. | intranasal inoculation of c3h/hen mice with propionibacterium acnes activates pulmonary macrophages but not splenic or peritoneal macrophages. when mice so treated were injected iv with tumor cells, no protection against the challenge was seen. conversely, inoculation of c3h/hen mice with p. acnes by the ip route activated splenic and peritoneal macrophages but not pulmonary macrophages. when mice with activated splenic and peritoneal macrophages were challenged with an iv injection of tumor cel ... | 1986 | 3464675 |
| bacterial aspects of chronic blepharitis. | patients with all forms of chronic blepharitis were thoroughly evaluated. these patients were found to have evidence for a primary bacterial component in the disease process only in the clinical staphylococcal and mixed seborrheic/staphylococcal forms of chronic blepharitis. evidence was found for a shared common pathway for staphylococcus aureus, coagulase negative staphylococci, and propionibacterium acnes to contribute to the disease process. these organisms were found to produce lypolytic ex ... | 1986 | 3466455 |
| response of bacterial antigen in palmoplantar pustulosis. | motilities of leukocytes in response to bacterial antigens or sera were examined in tissues from patients with palmoplantar pustulosis (ppp). accelerated migration towards bacterial antigens was detected in the case of staphylococcus epidermidis in 9 of 19 patients, to propionibacterium acnes in 5 of 19, to proteus mirabilis and staphylococcus aureus in 3 of 19, while no acceleration was found in neutrophils from the controls. a significantly accelerated migration of normal lymphocytes in respon ... | 1986 | 3820277 |
| induction of the plateau phase and rescue of mopc 104e by nonspecific immunization. | the enhancement of mopc 104e myeloma growth by nonspecific immunostimulation with c. parvum or immunization with sheep red blood cells and levan mixture was evaluated in balb/c mice. we observed increased levels of serum mopc 104e igm and early mortality in the tumor-bearing mice following treatment with c. parvum or antigenic stimulation. the enhancement of tumor growth observed was due to the production of lymphokine mitogenic factors produced in response to the nonspecific immunostimulation. | 1986 | 3828861 |
| infections after craniotomy: a retrospective study. | a retrospective study was performed to evaluate the rate of infection directly related to craniotomy. of 246 craniotomies performed in 1981, 234 could be evaluated. the overall incidence of infection was 8.1% (19 infections in 18 patients). the infection rate was 15.2% after insertion of a ventricular shunt (seven infections after 45 ventriculostomies). staphylococcus aureus, staphylococcus epidermidis and propionibacterium acnes were the most frequent isolated micro-organisms. we recommended a ... | 1986 | 3701096 |
| failure to boost the increased clearance of embolic tumor cells from the lung with dose scheduling: corynebacterium parvum studies. | initial suboptimal, optimal and supraoptimal doses of intraperitoneal corynebacterium parvum were followed by 'booster' doses injected intraperitoneally 5, 10 and 25 days later. mice were challenged intravenously 4-6 days after the booster doses with [125i]iurd-labeled b16 tumor cells and the extent of clearance of these cells from the lungs analyzed 4 h later. in a second experiment, mice were given booster doses of c. parvum on days 4, 7 and 10 and then challenged on day 14 with labeled b16 tu ... | 1986 | 3703464 |
| antitumor and immunologic effects of a pyridine-extracted fraction of propionibacterium acnes. | the antitumor and immunological effects of a pyridine extractable fraction of propionibacterium acnes were tested in a murine ovarian teratocarcinoma (mot) model. previous studies have demonstrated that tumor rejection in this model depends upon sequential activation of tumoricidal neutrophils (pmns) followed by cytostatic macrophages. the pyridine extract significantly prolonged the survival of mice challenged with 10(3) or 10(4) mot cells but had little impact on a 10(5) tumor inoculum. in viv ... | 1986 | 3708631 |
| cytolytic interactions between murine macrophages, tumor cells, and monoclonal antibodies: characterization of lytic conditions and requirements for effector activation. | because of recent successes in inducing the effective rejection of neoplasms in vivo by administration of monoclonal antibodies (mab), we analyzed lytic interactions in vitro that occur between macrophages and several combinations of tumor targets and mab that can lead to such successful immunotherapy. murine macrophages, interacting with mab of the igg1, igg2a, igg2b, and igg3 isotypes directed against sw-1116 carcinoma cells, destroyed the tumor targets efficiently over 24 to 48 hr in vitro. l ... | 1986 | 3711663 |
| [antitumor efficacy of activated macrophages against murine glioma cells]. | a crucial manifestation of malignant gliomas is the regrowth of already-invaded neoplastic cells after surgical intervention. one possible approach for inhibiting such tumor growth is to utilize the tumoricidal potential of macrophages. in order to investigate the clinical application of this concept, peritoneal exudate cells (pec) activated in vitro and in vivo by immunomodulating agents were tested for cytotoxic activity against murine glioma (203-glioma) cells. as immunomodulating agents, hea ... | 1986 | 3717955 |
