Epub 2008 Feb 15. Links Seven A, Güzel S, Aslan M, Hamuryudan V. Department of Biochemistry, Cerrahpaºa Medical Faculty, Istanbul University, Istanbul, Turkey. arzu_seven(a)hotmail.com OBJECTIVES: To investigate lipid, protein, DNA oxidation and antioxidant status in blood and synovial fluid of rheumatoid arthritis (RA) patients and to determine the importance of oxidative stress parameters in reflecting disease activity. DESIGN AND METHODS: 20 RA patients and 15 healthy controls were included. Lipid peroxidation (thiobarbituric acid reactive substances (TBARS), lipid hydroperoxide, and conjugated diene), protein oxidation (carbonyl and thiol), DNA oxidation (8-OHdG) and antioxidant status markers (glutathione (GSH), glutathione peroxidase (GSH Px), superoxide dismutase (CuZn SOD), and catalase) were determined in blood and synovial fluid. RESULTS: TBARS (p<0.001), lipid hydroperoxide (p<0.001), conjugated diene (p<0.001), carbonyl (p<0.001) and 8-OHdG (p<0.01) levels were significantly higher; thiol (p<0.01) and GSH levels (p<0.01) and GSH Px (p<0.001) and CuZn SOD (p<0.01) activities were significantly lower in blood of RA patients. TBARS (p<0.001), lipid hydroperoxide (p<0.001), conjugated diene (p<0.01), carbonyl (p<0.001) and 8-OHdG (p<0.05) levels were significantly higher, catalase activity (p<0.001) significantly lower in synovial fluid of RA patients. CONCLUSIONS: Increased lipid, protein and DNA oxidation markers and impaired antioxidant status confirm the role of oxidative stress in the pathogenesis of RA. Lipid peroxidation markers can serve as surrogate markers for disease activity.

Polla BS Laboratoire de Physiologie Respiratoire, UFR Cochin Port-Royal, Paris, France. Barbara.Po...(a)cochin.univ-paris5.fr The recent finding of the beneficial effects of iron deprivation in the outcome of muscle necrosis in an animal model of genetic myopathy served as the basis of this commentary. Here, "taking away" iron by controlled dietary deprivation is proposed as a reasonable, feasible, cheap, and efficient clinical approach to many diverse diseases, all of which have a free radical component. Indeed, iron potentiates the generation of the highly reactive and toxic hydroxyl radical, and, thus, of oxidative damage. Iron deprivation may represent the first really efficient antioxidant, preventing oxidative stress in all subcellular compartments, tissues, and organs. Iron/iron deprivation also modulates programmed cell death (apoptosis), which should be the subject of further studies to better define the mechanisms mediating these complex effects. Finally, related to its antioxidant effects, iron deprivation may find applications in the anti-aging field, whether programmed or premature aging, and whether in cosmetics or in gerontology. PMID: 10353254, UI: 99279694 -------------------------------- CONCLUSION In conclusion, therapy by taking away (iron) has a great potential for many different diseases, all of which share ROS-mediated mechanisms. The development of new, non-toxic , easily administrable iron chelators such as IRCO11 may shortly become the most efficient and fashionable antioxidant, anti-aging, anti-infectious, and anti- inflammatroy therapy. In the meantime, although taking away by controlled dietary deprivation is less attractive , it should be considered in all of the above, as well as in the currently incurable, devastating genetic or acquired myopathies such as DMD.

Fungistatic activity of iron-free bovin lactoferrin against several fungal plant pathogens and antagonists. Lahoz E, Pisacane A, Iannaccone M, Palumbo D, Capparelli R Nat Prod Res 2008 Jul; 22(11):955-61. Lactoferrin (LF) is a member of the transferrin family of iron- binding glycoproteins. It is also a multifunctional protein of 80 kDa that is synthesized by glandular epithelial cells and secreted into mucosal fluid. High levels of LF are present in colostrom and milk and low levels in tears, saliva, and gastrointestinal and reproductive secretions. Data regarding the antifungal effects of LF are limited. Studies have been performed on Candida albicans, which demonstrated that LF inhibits the growth of this fungus. This study reports the results of experiments carried out in order to evaluate the effects of LF on the growth of 11 fungi, which were isolated from plants and soils. These experiments employed the methods of amended agar utilizing nine different concentration levels of LF (0, 0.001, 0.01, 0.1, 1, 10, 100, 1000, 5000 mg L(-1)). The effects of LF on the growth of these fungi were based on measures of the radial growth of the fungal colonies expressed both as percentage of inhibition and as IC(50) values (the concentration at which the fungal growth was inhibited by 50% relative to controls). LF had no effects on Alternaria alternata, Gliocladium roseum, Fusarium solani and Colletotrichum lindemuthianum. It did, however, inhibit the growth of Aspergillus niger, Trichoderma viride, Sclerotinia sclerotiorum, Sclerotium rolfsii, Rhizoctonia solani and Phoma exigua to the point that their IC(50) values ranged from 31.1 mg L(-1) for S. sclerotiorum to 952 mg L(-1) for T. viride.
