A wide spectrum of human lung diseases is characterized by the presence of granulomas. Although understanding of the pathways leading to their development remains incomplete, data from in vitro studies suggest that neutrophils, monocytes, and their secreted products (eg, hydrogen peroxide, H2O2)
The level of plasma lipid peroxidation was followed up in 66 patients with systemic vasculitides with autoimmune pathogeny (SLE and SV) treated with corticoid compounds. The effect of vitamin E associated to this treatment was also studied. The change of the redox cycle, of the red cell glutathione,
Blood glutathione-peroxidase (GSH-Px) was determined in 61 healthy subjects and 506 patients with various skin disorders. Depressed levels were observed in patients with psoriasis, eczema, atopic dermatitis, vasculitis, mycosis fungoides and dermatitis herpetiformis. Low values of GSH-Px were also
An acute lens-induced necrotizing intraocular inflammation was produced in Lewis rats. Treatment of these animals by intraperitoneal injection of glutathione peroxidase resulted in marked decrease in uveal inflammation, retinal edema, hemorrhage and vasculitis. Intraperitoneal injection of
OBJECTIVE
To measure the levels of oxidation and peroxidation products of membrane constituents chiefly lipids produced by oxygen and lipid free radicals as thiobarbituric acid reacting substances (TBARS), reduced glutathione (GSH) and the antioxidant enzymes, superoxide dismutase (SOD) and
OBJECTIVE
Behçet's disease (BD) is an inflammatory vasculitis with immunologic, endothelial and neutrophil alterations. Adenosine deaminase (AD) is a marker of T-cell activation and is related to the production of reactive oxygen species by neutrophils with the production of NO(*), O(2)(*-),
Monocyte chemoattractant protein-1 (MCP-1) is a pivotal mediator of angiocentric granuloma formation in glucan-induced pulmonary granulomatous vasculitis. Based on the rationale that mononuclear phagocytes retrieved from granulomas are rich sources of nitric oxide (NO) and that the recruitment of
OBJECTIVE
Various cancer studies have suggested that polymorphism of GSTM1 may influence the ability to detoxify chemicals in cigarette smoke. In the present study the effect of smoking on clinical features of Behçet's disease were investigated in patients having GST-M1 and/or -T1 null
Full-length human retinal cDNA for S antigen (S-ag) and for the alpha subunit of transducin (alpha-Td) were subcloned into a bacterial expression plasmid vector to generate recombinant fusion proteins with glutathione-S-transferase (GST). The recombinant GST-S-ag and rGST-alpha-Td fusion proteins
Generation of oxidative stress induced by reactive oxygen species (ROS) and nitrogen (RNS) is believed to be a primary factor in the etiology of various inflammatory diseases. Although, the process of generation of oxygen species is a physiological event, in the inflammatory process this event is
The administration of mercuric chloride (HgCl2), gold compounds, or D-penicillamine to Brown Norway (BN) rats causes a T helper (Th)2 cell-associated autoimmune syndrome characterized by the production of a number of autoantibodies, marked elevation of serum IgE concentration, and tissue injury in
Eales' disease (ED) is an idiopathic retinal periphlebitis characterized by capillary non-perfusion and neovascularization. In addition to the existing system, a new staging system has been proposed by Saxena et al. Immunological, molecular biological and biochemical studies have indicated the role
BACKGROUND
Cutaneous adverse drug reactions (CADRs) may either be immunological or non-immunological. The precise mechanisms, however, are largely obscure. Other concomitant mechanisms may amplify and/or contribute to the severity and duration of a reaction. One such mechanism could be oxidative
Six of the 33 calves born in a Swedish dairy herd during a period of four months developed laminitis when they were eight to 12 weeks old. The clinical signs included difficulty in rising, a stiff gait, overgrown claws and haemorrhages in the sole horn. Samples of blood were taken from four of the
OBJECTIVE
To evaluate the role of reactive oxygen molecules (ROMs) in the pathogenesis of Henoch-Schönlein purpura and the effect of vitamin E on oxidative damage. ROMs have been suggested to contribute in many pathological conditions including renal diseases and vasculitis.
