Dysregulation of tumour necrosis factor alpha (TNF alpha) production is thought to be important in rheumatoid arthritis. Since pentoxifylline and thalidomide inhibit endotoxin induced TNF production in vitro, these drugs were tested in an open study in rheumatoid arthritis patients to assess toxicity, the effect on TNF production, and the antiarthritic effects.

In 14 patients with stable angina pectoris we examined the effect of pentoxifyline (PTX) on oxidative metabolism of TNF-alpha-priming neutrophils. The control group consisted of 21 patients with stable angina pectoris without pentoxifylline administration. Blood samples for examination were taken from basilic vein (peripheral blood) and coronary sinus immediately before PTCA procedure. In PTX-group was found the significant decrease in spontaneous CL of TNF-alpha-priming neutrophils from coronary sinus blood (1231.0 +/- 119.4 mV x min), in comparison to the control group (1374 +/- 124.4 mV x min). In PTX-group was found the significant decrease in fMLP stimulated CL of TNF-alpha-priming neutrophils from peripheral blood (4219.0 +/- 707.2 mV x min) and coronary sinus blood (4322.0 +/- 664.4 mV x min), in comparison to the control group (5248.0 +/- 595.8 mV x min and 4973.0 +/- 536.5 mV x min; respectively). There were no differences between both groups in PMA stimulated CL of TNF-alpha-priming neutrophils.

Pentoxifylline (PTX) has potential usefulness in HIV-seropositive patients due to its beneficial effects on renal function, its inhibitory effects on tumor necrosis factor alpha, and its vascular effects on microcirculatory disturbances. The present study prospectively evaluated the effects of multiple oral doses of PTX (400 mg three times daily for 12 weeks) on renal function in 11 HIV-seropositive patients compared with 14 control patients. Four of these patients had HIV-associated nephropathy, manifested by high urinary microalbumin outputs (72 +/- 56 micrograms/min; mean +/- SD). Ambulatory 24-h urine collections were analyzed for creatinine, electrolytes, and immunological markers at weekly intervals for 12 weeks. Urine flow rates diminished to one-half baseline values by week 12; changes were related to both time and treatment sequences. There were significant decreases in creatinine clearances and electrolyte excretion rates over the study period that were not associated with treatment regimens. No differences were found in fractional electrolyte, uric acid, microalbumin, and neopterin excretion rates either between or within groups. One subject with high microalbumin excretion rates had a significant drop over the 12 weeks (133 to 4 micrograms/min); the other 3 subjects had similar or elevated microalbumin outputs by the end of the study. Although well tolerated, therapeutic doses of PTX did not significantly affect renal function in HIV-seropositive patients.

In the Per Protocol Set (PPS), PWT of the intervention group increased 1.6±1.6 minutes after treatment (p<0.05). With PLC treatment, CT was significantly decreased in the treatment group. ABI was increased in both treatment and control groups. However, no statistical significance was found. In the Safety Analysis Set (SS), there were 110 adverse events during the course of the study (67 in PLC group vs. 43 in control group). There were two serious adverse events in the PLC group and four in the placebo group. All of the SAEs were assessed as unrelated to the study drug which indicated that PLC was well-tolerated in PAD patients.

This in vitro study was designed to examine changes of red cell microrheological parameters (red cell aggregation and their suspension viscosity) after cell incubation with some drugs having phosphodiesterase (PDE) inhibitory activity (pentoxifylline - 25.0 microg/ml; drotaverine - 10.0 microg/ml; vinpocetine - 5.0 microg/ml; papaverine - 10.0 microg/ml; caffeine - 25.0 microg/ml; 3-isobutyl-1-methylxanthine [IBMX] - 10.0 microg/ml). Concentrations of used drugs for in vitro red cell microrheology study were the similar with those which it could be possible in blood of patient after intravenous therapeutic infusion. Red blood cells were separated from the blood by centrifugation at 1400 g for 15 min and washed 3 times with phosphate buffered saline (PBS). The washed RBCs were then resuspended in PBS at a hematocrit of approximately 40%. In each of the research sessions these RBC suspensions were divided into two aliquots and exposed to: one of the drug at 37 degrees C for 15 min; remaining aliquot (red cell suspension with PBS) was kept at 37 degrees C for 15 min and served as the control. It was found that all of used drugs decreased red cell aggregation and their suspension viscosity significantly. Since IBMX and vinpocetine are the specific inhibitor PDE activity it might be suppose that cellular PDE is molecular target in RBCs for this class of drugs. The obtained data reveals evidence that drugs, acting as PDE inhibitors, might be considered as microrheologically positive remedies.

Ciprofloxacin works through interfering with replication and transcription of bacterial DNA, which leads to increased oxidative stress, and death of bacterial cells. Drugs with strong antioxidant such as tempol, melatonin and pentoxifylline might interfere with the antibacterial activity of ciprofloxacin. In the current study, the effect of these drugs on the cytotoxicity of ciprofloxacin was investigated against several reference bacteria. Standard bacterial strains included Escherichia coli ATCC 35218, Staphylococcus aureus ATCC29213, Pseudomonas aeruginosa ATCC 9027, Staphylococcus epidermidis ATCC 12228, Acinetobacter baumannii ATCC 17978, Proteus mirabilis ATCC 12459, Klebsiella pneumoniae ATCC 13883, methicillin-resistant Staphylococcus aureus (MRSA) (ATCC 43300), and Streptococcus pneumoniae (ATCC 25923). The antibacterial activity of ciprofloxacin with or without treatment of bacterial cells by tempol, melatonin or pentoxifylline was assessed using the disc diffusion method and by measuring the minimum inhibitory concentration (MIC) and zones of inhibition of bacterial growth. All of the tested bacterial strains were sensitive to ciprofloxacin. When treated with tempol, melatonin or pentoxifylline, all bacterial strains showed significantly smaller zones of inhibition and larger MIC values compared ciprofloxacin alone. In correlation, reactive oxygen species (ROS) generation induced by ciprofloxacin antibacterial action was diminished by treatment of bacterial cells with tempol, melatonin or pentoxifylline. In conclusion, results indicate the possible antagonistic properties for agents with antioxidant properties such as tempol, melatonin and pentoxifylline when they are used concurrently with flouroquinolones. This could be related to the ability of these agents to inhibit oxidative stress in bacterial cells.

Using guinea pigs, a study was conducted on the effects of KBT-3022, a new anti-platelet agent, on hemorheological properties in various tests including blood filterability, blood viscosity, shear stress-induced red blood cell (RBC) deformability and contents of ATP and 2,3-diphosphoglycerate (2,3-DPG). Oral administration of KBT-3022 at 1 and 10 mg/kg significantly increased blood filterability, and significantly reduced blood viscosity at 10 mg/kg without changing the hematocrit, plasma fibrinogen concentration or plasma viscosity. KBT-3022 (10 mg/kg, p.o.) improved RBC deformability in response to shear stress, which was evoked by passing the blood through a thin tube. This dose of KBT-3022 also increased the contents of ATP and 2,3-DPG in RBC. These findings indicate that KBT-3022 may reduce blood viscosity as a sequel to improvement of RBC deformability through direct action on RBC. The increase in the intracellular levels of ATP and 2,3-DPG was considered to be involved in this improvement of hemorheological properties. These hemorheological effects of KBT-3022 appear to be promising for the treatment of patients with ischemic vascular disease.

This study was conducted to determine whether pentoxifylline has an in vitro effect on sperm motion characteristics in normozoospermic men. The subjects of the study were 15 male volunteers. After the spermatozoa were washed with mBWW medium, the sperm suspension was divided into two aliquots: one was treated with 1 mg/ml pentoxifylline, the other was used as a control. The sperm motion characteristics were examined by an HT-M2030 at 30, 60, 120, 180, 240 and 300 min during continuous exposure to the drug. As results, pentoxifylline increased the curvilinear velocity and the lateral head displacement. However, it did not affect sperm motility, the straight line velocity. Pentoxifylline may improve sperm fertilizing ability by altering the characteristics of sperm motion, not by increasing the number of motile spermatozoa.

Serum levels of liver enzymes, blood ammonia and prothrombin time and the stage of hepatic encephalopathy were significantly improved in rats treated with dimethylsulfoxide or dimethylthiourea compared to the other treatment groups (p<0.001). Liver histology and the survival rate in these rats were not adversely affected by thioacetamide administration (p<0.001), while in all the other treatment groups those parameters were similar to control rats with fulminant hepatic failure. Furthermore, dimethylsulfoxide ameliorated liver damage and improved survival even when its administration was initiated 8 and 16 h after the first thioacetamide injection. The hepatic concentration of methanesulfinic acid, which is produced after direct interaction of dimethylsulfoxide with hydroxyl radicals, was increased five-fold in rats treated with thioacetamide+dimethylsulfoxide (p<0.001), suggesting a role for hydroxyl radical scavenging in the protection from fulminant hepatic failure in this model. In the group of thioacetamide-treated rats that were pretreated with L-NAME, liver enzymes, blood ammonia levels and the mortality rate were higher than in the control group, treated with thioacetamide only.

A mature-onset diabetic patient who developed microangiopathic hemolytic anemia (MHA) is presented. Although numerous causes of hemolysis are reported in the literature, MHA is a rare complication of diabetes. The proposed mechanism of hemolytic anemia is thought to be related to the abnormal formation of cell membranes in the diabetic environment. The ratio of cholesterol to phospholipid in the core of the membrane is altered in diabetics; as a result, the red blood cell wall becomes rigid and nondeformable. The abnormal cells becomes disrupted as they circulate through the microangiopathic blood vessels. The mechanism of action of the antiplatelet agents is to enhance cell membrane compliance. With improved cell-wall compliance, one can expect a reduction in hemolysis, as occurred in our patient. The literature on diabetes mellitus-related microangiopathic hemolytic anemia is reviewed.

The mechanism of the early stage of metastasis formation by sticky blood-born cancer cells is discussed. Abnormal platelet aggregation to circulating and lodged cancer cells, as well as alterations of blood coagulation and fibrinolysis play an important role. The reducing effect of several platelet aggregation inhibitors on cancer cell stickiness and tumor embolism mortality has been investigated in rats after intravenous transplantation of 1 X 10(6) Walker-256 carcinosarcoma cells. The tested substances diminished platelet aggregation to circulating cancer cells, leading to a dose-dependent inhibition of cancer cell lodgment to the endothelium. Furthermore, some of the substances prevented lethal pulmonary tumor cell embolism which was observed in 60% of the controls. These results are interpreted by assuming an inhibition of disseminated intravascular coagulation which occured after intravenous transplantation of Walker-256 carcinosarcoma. On this basis a clinical long-term study for metastasis prophylaxis was started more than 4 years ago with one of the tested substances, the dipyridamole derivative RA 233, in 40 patients with sarcoma or malignant lymphoma of the head and neck region. The provisional results obtained in matched pairs are discussed.

Methods were developed to test angiogenic response to human tumor implants and various biologic agents in the cornea of rabbits and non-human primates (Macaca arctoides). Crude PDGF preparations were found to have significant angiogenic effect. Purified, recombinant PDGF preparations were also effective inhibitors (e.g. pentoxifylline (Px) (which also were found to release PgI2 and t-PA) inhibited human tumor implant induced angiogenesis and reduced spontaneous metastases in 3 transplantable murine tumors (Furth-Columbia Wilms' tumor in Furth-Wistar rats, C-1300 neuroblastoma in A/J mice and HM-Kim mammary carcinoma in Wistar rats) but not in the NIH adenocarcinoma in Balb/c mice. Sodium diethyldithiocarbamate (DDTC), a metal complexing agent with special affinity to copper buy trental online and anti-thyroid as well as, immune stimulating activity was shown to be anti-angiogenic and to potentiate the effect of Px. The anti-fibrinolytic agents epsilon amino caproic acid (EACA) and tranaxamic acid (t-AMCHA) were anti-angiogenic. DDTC and Px were synergistic from this point of view.

Many patients with peripheral arterial disease (PAD) have intermittent claudication or problems with ambulation and mobility buy trental online . Exercise and smoking cessation are primary therapies for claudication, but drug treatment may provide additional benefit. The data supporting use of pentoxifylline for claudication are weak, and pentoxifylline is not generally accepted as efficacious. Cilostazol is a new drug for the treatment of claudication. It appears to modestly benefit walking ability and it has other potentially useful effects, including inhibition of platelet aggregation and beneficial effects on serum lipids. In a randomized, prospective, double-blind trial examining walking ability in patients with PAD with moderate-to-severe claudication, cilostazol was superior to both placebo and pentoxifylline.

The present work explored the anti-platelet effect produced by the quinone fractions (17.8, 35.7 and 71.4 microg/ml) isolated from the heartwood of Auxemma oncocalyx Taub. Our results show that the quinone fraction (QF) is a reversible and concentration-dependent inhibitor of human platelet aggregation induced by ADP, arachidonic acid (AA), collagen and thrombin. Besides, the QF effect was significantly potentiated after its association with aspirin or imidazole, and in this case, the AA-induced platelet aggregation was completely blocked. The addition of QF to L-arginine caused a small but significant increase in the percentage of platelet inhibition (13%) only when compared to QF alone. Finally, the addition of QF to pentoxifylline, a known phosphodiesterase inhibitor, resulted in significant potentiation (43% inhibition) of the antiplatelet effects seen with QF (9.7%) or PTX (10%) alone. Although QF presented an antiplatelet effect, it caused a significant decrease in bleeding time, manifested 3 h after oral (100 or 200 mg/Kg) or 1 and 3 h after intraperitonial (30 mg/Kg) administration. In conclusion. QF possibly acts through a combined cyclo-oxygenase and TxA2 synthase inhibition. Besides, QF also increases platelets cAMP levels which also contributes to its anti-aggregatory buy trental online effects.

Compared with the control group, PTX treatment reduced fibrosis scores at d 7 and d 14 (P<0.05). The reduction was accompanied by inhibited expression of transforming growth factor-beta 1 (TGFbeta1), a key cytokine in tubulointerstitial fibrogenesis (P<0.01). Meanwhile, VEGF protein and mRNA in the kidney were increased in the PTX-treated group compared with the control group (P<0.01). PTX up-regulated expression of VEGF mRNA in a dose- and time-dependent manner in cultured HK-2 cells (P<0.01). However, expression of HIF-1alpha (a key transcription factor for VEGF gene expression) was unchanged by PTX treatment. PTX prolonged the half- buy trental online life of VEGF mRNA by a 1.07-fold increase.

Antifibrotic therapies are preferentially targeted to the activated mesenchymal cells in the liver that synthesize an excess of matrix proteins and resemble the myofibroblasts of healing wounds. These cells derive from normally quiescent hepatic stellate cells and (myo-) fibroblasts. Their activation is triggered and maintained by several fibrogenic modulators and cytokines, but also by buy trental online mechanical stress. Whereas many agents inhibit stellate cell/myofibroblast proliferation and collagen synthesis in vitro, only few of them are tolerable or effective in suitable animal models in vivo. An antifibrotic effect was demonstrated for silymarin, a defined mixture of flavonoids, sho-saiko-to which contains the related compound baicalein, for halofuginone, another plant-derived agent, for the phosphodiesterase inhibitor pentoxifylline and for LU135252, an oral inhibitor of the endothelin-A-receptor. The retrospective finding that interferon-alpha therapy for hepatitis C may halt or even reverse fibrosis, has to be confirmed in prospective randomized trials. Strategies to inhibit the profibrogenic cytokines transforming growth factor (TGF)-beta or connective tissue growth factor (e.g. by soluble decoy receptors) are evolving, but have not been convincing yet. Drug targeting to the fibrogenic liver cells is now possible by use of cyclic peptides that bind to receptors which are specifically up-regulated on activated stellate cells, for example those for platelet-derived growth factors or collagen type VI. In addition, blockade of such activation receptors can induce stress-relaxation which reverts the fibrogenic cells to a fibrolytic, collagen degrading phenotype. Combined with the evolving validation of serological markers of fibrogenesis and fibrolysis an effective and individualized treatment of liver fibrosis can be anticipated.

Microglia, the resident macrophages of the brain, secrete a number of mediators involved in neural-immune function. The cytokines, IL-1 alpha and TNF alpha, are two such factors which are stored as inactive precursor molecules requiring post-translational proteolytic processing prior to release. From investigations of second messenger pathways involved in regulating the secretion of these cytokines, we have demonstrated that the PKC inhibitor, H-7, blocks the induction of TNF alpha secretion induced by LPS. In contrast, H-89 and HA-1077, inhibitors of cyclic nucleotide-dependent protein kinases (PKA and PKG), did not alter LPS-stimulation of TNF alpha release. Consistent with these observations, the weak PKC activator, mezerein, induced TNF alpha secretion in an buy trental online H-7-reversible manner. In marked contrast, PKC activation did not induce IL-1 alpha secretion and H-7 potentiated IL-1 alpha release. In the case of the protein phosphatase inhibitor, okadaic acid, secretion of both cytokines was induced, indicating that protein phosphorylation is important for the induction of cytokine secretion but only in the case of TNF alpha is PKC involved. In the case of IL-1 alpha, a tonic inhibitory regulation involving PKC activation may be present. We therefore conclude that alterations in phosphorylation-dephosphorylation cycles may be important triggers in the switching of microglial cellular function from a resting to an activated state.

Pneumonic pasteurellosis was experimentally induced in calves by inoculation of 5 x 10(8) Pasteurella haemolytica organisms into the right diaphragmatic lung lobe. Blood and bronchoalveolar lavage fluid samples were obtained prior to inoculation and at postinoculation hour (PIH) 2, 4, and 6. Calves developed acute lung injury, characteristic of pneumonic pasteurellosis. Lesions were found only in the right diaphragmatic lobe. By PIH 4, significant (P less than 0.01) increases were detected in lavage fluid total cell count, neutrophil count, total protein and albumin concentrations, and alkaline phosphatase (ALP) and lactic dehydrogenase (LD) activities. Myeloperoxidase and elastase activities did not increase. Neutrophil depletion ameliorated the lung lesions and prevented the increase in lavage fluid cell count, buy trental online total protein, and albumin concentrations and ALP and LD activities. Treatment with the iron chelator, deferoxamine mesylatehydroxyethyl starch, attenuated the increase in total protein and albumin concentrations and ALP and LD activities at PID 4, but not PIH 6. Treatment with a neutrophil function inhibitor, pentoxifylline, prevented the increase in lavage fluid neutrophil numbers, but accentuated the increase in total protein and albumin concentrations, and ALP, LD, myeloperoxidase, and elastase activities.

Dual parameter flow cytometry measuring DNA and BrdUrd uptake in "stripped" nuclei was used as a sample preparation procedure. The utility of this method is demonstrated in a human ovarian cell line (BG-1) by two parameter flow cytometric analysis of DNA and bromodeoxyuridine (BrdUrd) incorporated into the DNA. BG-1 cells, treated with cisplatin followed by constant exposure to pentoxifylline, produce G0/G1, S phase, and G2/M perturbations. The G0/G1 population is greatly diminished. Large numbers of cells are distributed in S phase in which a large portion is incapable of DNA synthesis. The G2/M perturbations show a continually increasing block over a time course of 168 h. The identification of two types of S phase cells (DNA synthesizing and DNA nonsynthesizing) is clearly shown with the use of BrdUrd incorporation as a second parameter in addition to flow cytometric analysis of DNA. This increase in the non-DNA-synthesizing S phase population corresponds to an enhancement of cytotoxicity when cells are treated with the combination of cisplatin and pentoxifylline. It is felt that buy trental online this technique provides a useful method to investigate the dynamics of the cell cycle perturbations affected by modulators of chemotherapeutic agents.

Gastroenterologists and hepatologists believe that AH Trileptal Overdose Emedicine patients be routinely checked for HCV. However, there is lack of consensus on choice of drug for treatment and outcome of HCV positive AH patients. Studies are needed to develop guidelines for management of HCV infected AH patients.

a) We measured PaO2, PaCO2, and pH, and recorded airway pressure and systemic blood pressure at 15, 10, and 5 mins before oleic acid injection and at 6, 10, 15, 35, 55, and 75 mins after oleic acid injection. Compared with the control groups, a decrease in PaO2 by oleic acid was significantly prevented when pentoxifylline (5 or 20 mg/kg) was administered 40 mins before oleic acid injection. However, a decrease in PaO2 by oleic acid was not significantly reduced when pentoxifylline was administered 3 mins before oleic acid injection. Pentoxifylline administered 13 mins after oleic acid injection did not affect the recovering course of PaO2 significantly. b) An increase in pulmonary vascular permeability by oleic acid was significantly attenuated by both pentoxifylline and theophylline. The effect of theophylline was significantly stronger than the effect of pentoxifylline in the Propecia Normal Dosage main bronchi. The effect of theophylline was not significantly different from the effect of pentoxifylline in other areas.

Levels of tumour necrosis factor (TNF Aciphex Tablet ) are increased in patients with HIV infection leading to increased apoptosis and reduced CD4 cell life. Pentoxiphylline is a TNF inhibitor with properties that might make it useful for the treatment of HIV infection. These include improved cell mediated immunity and inhibition of viral replication. We carried out this study to determine the therapeutic utility of pentoxiphylline in improving constitutional manifestations, preventing opportunistic infections and sustaining CD4 counts among asymptomatic HIV infected individuals (i.e., those with no opportunistic infection).

Cocaine and CMV each have been suggested to promote the progression of HIV-1 infection. In the present study, the interaction of cocaine and CMV was investigated in a PBMC coculture assay in which release of HIV-1 p24 Ag into coculture supernatants was used as an index of HIV-1 replication. CMV was an effective activation signal for HIV Lamictal Xr Reviews -1 replication when PBMC from CMV-seropositive donors were used in the coculture assay, and cocaine markedly increased replication of HIV-1 in these cocultures. The synergistic activity of cocaine was reduced by neutralizing antibodies to TNF-alpha and by pentoxifylline, an inhibitor of TNF-alpha mRNA production. Also, antibodies to transforming growth factor-beta (TGF-beta) eliminated the amplifying effect of cocaine on HIV-1 replication, whereas antibodies to IL-6 were inactive. The potentiating effect of cocaine could be reproduced by addition of rTNF-alpha or rTGF-beta to the cocultures of CMV-activated PBMC, although TGF-beta was substantially more potent than TNF-alpha. The possibility that TNF-alpha may act indirectly through stimulation of TGF-beta was suggested by the finding of reduced TGF-beta levels in culture supernatants of PBMC that were treated with CMV and cocaine in the presence of antibodies to TNF-alpha. Thus, cocaine amplifies HIV-1 replication in cocultures containing CMV-activated PBMC via a mechanism that appears to involve both TNF-alpha and TGF-beta. The results of this study support the possibility that cocaine and CMV could enhance HIV-1 replication and, thus, aggravate HIV-1-related disease.

We tested the combination of phosphodiesterase (PDE) 3 and PDE4 inhibitors as an interventional approach to prevent the development of brain damage after Shiga toxin (Stx)-producing Escherichia coli (STEC) infection, using mice with protein calorie malnutrition. The combination consisted of pentoxifylline and rolipram; the dose of each inhibitor was 7.5 mg/kg. Treatment with this combination, which was administered intraperitoneally twice daily at 12-h intervals, increased serum concentrations of each inhibitor to >2 microg/mL and afforded significant levels of protection when it was continued for 3 days, starting on day 2 (95% survival rate; P<.001) or day 3 (63% survival rate; P<.01) of infection. The treatment reduced plasma levels of Stx2; consequently, immunoreactions of Stx2 were not found in the brain, and survivors did not show neurologic symptoms. Protection was associated with decreased levels of tumor necrosis factor (TNF)- alpha and increased production of interleukin-10 in serum, the brain, and the cecum. Although the combination at doses >2 microg/mL reduced Gb3 content of and Stx2 binding to Caco-2 cells, its ability to suppress production Requip Xl Cost of TNF- alpha seemed to be more important for the decrease in cell-bound Stx2 in intestinal epithelial cells. Therefore, the combination of PDE3 and PDE4 inhibitors might be used as an interventional approach to prevent brain damage caused by STEC infection.
