Radiation therapy plays an important role as part of multimodality treatment for a number of childhood malignancies. The damaging effects of radiation on bone formation in children have been well documented. Recent work suggests that the postirradiation increase in cytosolic calcium is probably responsible for the deleterious effects of radiation on growth plate chondrocytes because it causes a...
BACKGROUND As oxidative stress contributes to both progression and pathologic complications of diabetes and effective therapeutic strategies to prevent or delay the damage remain limited, the aim of the present study was to assess the efficacy of pentoxifylline in reducing of oxidative stress. Since there is a relationship between nitric oxide (NO), epidermal growth factor (EGF) and oxidative s...
Ciprofloxacin-Induced Antibacterial Activity Is Atteneuated by Pretreatment with Antioxidant Agents.
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 i...
BACKGROUND Inflammatory immune activation commonly occurs in heart failure and may perpetuate this syndrome. We sought to determine whether the immunomodulating agent pentoxifylline enhances left ventricular function in patients with ischemic cardiomyopathy. We also investigated the effect of therapy on levels of brain natriuretic peptide (NT-pro BNP), C-reactive protein (CRP), tumor necrosis f...
Background: The trisubstituted methylxanthine derivative pentoxifylline inhibits hepatic stellate cell proliferation and collagen synthesis in vitro. The antifibrotic effect of pentoxifylline in a suitable in vivo model of chronic liver fibrogenesis remains to be tested. Methods: Groups of adult rats (n=20–23) received oral pentoxifylline at a dose of 8 mg/kg/day from week 1 to week 6, and 16 m...
Caffeine, pentoxifylline, and kallikrein are substances that affect the efficiency of sperms in the fertilization process; however, they have not been adequately studied. The present study aimed to examine the influence of caffeine, kallikrein, and pentoxifylline on sperm motility in bovine as well as investigate their optimum concentrations for increasing the movement of sperms in bovine. Froz...
A recent study published by Bianco et all has suggested that pentoxyifylline [3,7-dimethyl-1-(5-oxo-hexyl)-xanthine] reduces morbidity and mortality in patients undergoing bone marrow transplantation (BMT). When compared with a “good risk” control group, pentoxifylline recipients experienced less mucositis (3.7 v 18.7 days,P = .004), less hepaticvenocclusive disease (10% v 65%,P = .001), a lowe...
Cryopreservation causes extensive damage to spermatozoa, thereby impairing their fertilizing ability. The purpose of this study was to determine if the direct addition of pentoxifylline to the seminal plasma before cryopreservation improved sperm motility and acrosome reaction. Semen specimens from 15 healthy volunteers were divided into two aliquots. One aliquot was treated by adding 5 mM pent...
Background & Aims: It has been shown that some drugs such as Pentoxifylline (PTX) have immunomodulatory and anti-inflammatory activity that might represent a potential preventive therapy for autoimmune diseases. The purpose of this study was to investigate the therapeutic effects of pentoxifylline on the treatment of autoimmune diabetes in mice and its effects on expressions of peroxisome proli...
Pentoxifylline is a methylxanthine derivative that has been used for several decades in the symptomatic management of intermittent claudication. For reasons that remain fairly obscure, this drug benefits blood rheology in a number of complementary ways: decreasing blood and plasma viscosity, lowering plasma fibrinogen while promoting fibrinolysis, and improving blood filterability by enhancing ...
