Rheumatoid arthritis (RA) is an autoimmune disease responsible for significant human morbidity in modern life. However, oxidative stress is one of the key markers for determining pathophysiology of patients with RA. The interaction between cellular immune system and body's endogenous and/or exogenous antigens produce reactive oxygen species (ROS) and reactive nitrogen species (RNS) in autoimmune disease like RA. ROS and RNS include highly toxic superoxide (O2(-)) and peroxynitrite (ONOO(-)) radicals, which activate the signaling cascades of inflammatory cells to synthesize pro-inflammatory cytokines and chemokines...

(Z,Z')-Diligustilide (DLG) or levistolide A is a dimeric phthalide isolated from Ligusticum porteri (Osha), the roots of which are used in the traditional treatment of many diseases including gastric aches. However, its action has not been completely elucidated. We analyzed the contributions of hydrogen sulfide and S-nitrosothiols to the action of DLG. Animals were pretreated with freshly formed in vitro nitrosothiol using Na2S and sodium nitroprusside to elucidate participation in the action of DLG. We also evaluated the production of H2S in vivo and in real time on the stomach via a specific electrode introduced into the stomachs of anaesthetized animals pretreated with DLG...

Modafinil, an FDA approved wakefulness drug prescribed to narcolepsy patients, has recently been shown to have anti-inflammatory effects and provides protection against neuroinflammation. It is unknown if modafinil can also protect against atherosclerosis, pathogenesis of which implicates inflammation. Using an apoE-deficient mouse model, we tried to elucidate the effects of modafinil treatment on the development of atherosclerosis. We tested serum levels of cytokines. We isolated mouse bone marrow-derived macrophages (BMDMs), detected effect of modafinil on the viability and proliferation of BMDMs, and on oxidized low-density lipoprotein-induced IL-6 and TNF-α, and supernatant level of IFN-γ as well as NF-κB activity in BMDMs...

Ankylosing spondylitis (AS) is a debilitating chronic inflammatory disease with genetic predisposition, which is characterized by the involvement of spine and sacroiliac joints. Due to the relatively unsuccessful treatments, we designed β-D-mannuronic (M2000) with the beneficial effects in various experimental models as a novel non-steroidal anti-inflammatory drug (NSAID). The aims of our present study were: first, to compare the therapeutic effects of M2000, as a novel designed NSAID, with naproxen and placebo in Iranian patients with AS during 12 weeks; second, to evaluate the effect of M2000 on gene expression of cyclooxygenase enzyme (COX-1/COX-2), a key enzyme in the initiation of inflammatory pathways in AS patients; and third, to assess the activity of COX-1 and COX-2 enzymes in the presence/absence of M2000 at the different doses in the murine macrophage, J774 cell line...

Gout is a disorder that triggers a severe inflammatory reaction which generates episodes of intense pain and discomfort to the patient. Arctium minus (Hill) Bernh. (Asteraceae) is known as "burdock" and displays anti-inflammatory, antinociceptive, against rheumatic pain and radical-scavenging activities. Species of the genus Arctium have been used in assistant therapy of gout and other inflammatory processes. We investigated the antinociceptive and anti-edematogenic effects of the crude extract of A. minus seeds in an acute gout attack model induced by intra-articular injection of monosodium urate (MSU) crystals in adult male Swiss mice (25-30 g)...

Pulmonary fibrosis is a result of an abnormal wound healing in lung tissue triggered by an excessive accumulation of extracellular matrix proteins, loss of tissue elasticity, and debit of ventilatory function. NKT cells are a major source of Th1 and Th2 cytokines and may be crucial in the polarization of M1/M2 macrophages in pulmonary fibrogenesis. Although there appears to be constant scientific progress in that field, pulmonary fibrosis still exhibits no current cure. From these facts, we hypothesized that NKT cells could influence the development of pulmonary fibrosis via modulation of macrophage activation...

Hydrogen sulfide (H2S) is an endogenous mediator that contributes to many important physiological processes including vasodilation and vascular smooth muscle relaxation; in turn, preventing tissue damage and reducing inflammation. Heme oxygenase (HO) enzymes, of which HO-1 is inducible by harmful stimuli, were found to regulate intestinal inflammation in experimental animal models of colitis. We aimed to investigate the protective effects of H2S against 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis in rats, and whether HO enzyme system is involved in the H2S-induced colonic cytoprotection...
