BACKGROUND: Inflammatory bowel disease (IBD) [including Crohn's disease (CD) and ulcerative colitis (UC)] constitutes an important clinical problem. The pathogenesis of IBD remains unclear. It is believed that immune dysfunction, inflammatory mediators and oxidative damage play crucial roles in development of IBD. The condition is clinically associated with symptoms ranging from mild to severe during relapses, depending on the affected segment of the gastrointestinal tract. Bloody diarrhea with mucus, abdominal pain, weight loss and anemia are initial symptoms of both CD and UC...

Jun Zhang, Liang Chen, Yunyun Sun, Yuanhai Li
Tramadol is an analgesic drug and relieves pain through activating μ-opioid receptors and inhibiting serotonin and noradrenaline reuptake. Emerging evidence shows that it also stimulates immune cells, including NK cells, splenocytes, and lymphocytes, and elevates IL-2 production. However, it remains unknown whether and how tramadol directly affects macrophages. To answer these questions, we collected human umbilical cord blood, isolated macrophages, and examined their responses to tramadol. Although tramadol did not alter resting macrophages and the antigen-presenting function in lipopolysaccharide-activated macrophages, it regulated M1 and M2 macrophages, which are, respectively, transformed by IFN-γ and IL-4...

OBJECTIVE: Curcumin (diferuloylmethane), a major component of turmeric is well known for its anti-inflammatory potential. Present study investigates sequential release of inflammatory mediators post LPS challenge (10 mg/kg,i.p.) causing lung inflammation and its modulation by curcumin through different routes (20 mg/kg, i.p and 10 mg/kg, i.n.) in murine model. Dexamethasone (1 mg/kg, i.p) was used as standard drug. METHODS: Lung Inflammation was evaluated by histopathological analysis, myeloperoxidase (MPO) activity followed by inflammatory cell count and total protein content measurements in bronchoalveolar fluid (BALF)...

Chronic non-bacterial prostatitis (CNP) is the most common type of prostatitis and oxidative stress (OS) was shown to be highly elevated in prostatitis patients. This study aimed to investigate the protective effect of pentoxifylline (PTX) on CNP induced by carrageenan in rats. Male adult Wistar rats (n = 30) were divided into control, CNP and three treatment groups (n = 6) including CNP + cernilton and CNP + PTX groups. CNP was induced by single intraprostatic injection of 1% carrageenan (100 µl)...

Biologic agents have become indispensable in the management of autoimmune disease particularly rheumatological conditions. The lives of countless individuals have been improved following treatment with these drugs. Unfortunately, their cost prohibits more widespread use around the globe. This critical issue has been addressed by the introduction of biosimilars into the market. These therapies have been developed to resemble the originator molecule as closely as possible and to increase competition in the therapy area thus allowing costs to be reduced...

Emerging evidence proposes a link between immune changes and pain, which is consistent with the inflammation theory and the increased incidence of neurodegenerative diseases. Flavonoids have long been used because of their anti-inflammatory potential activity and they are considered a promising alternative to alleviate neuropathic pain. The aim of this study was to investigate the antihyperalgesic effect of hesperidin and the presence of pro-inflammatory cytokines evaluated at peripheral and central levels in the chronic constriction injury as model of neuropathic pain in rats...

The present study investigated the possible relationship between pro-inflammatory cytokines and programmed nigral neuronal death in rotenone model of Parkinson's disease (PD). Sitagliptin and liraglutide efficacy to inhibit the inflammatory-apoptotic degenerative process were investigated, too. The experimental PD were induced in male albino rats by ten subcutaneously injections of rotenone (3 mg/kg/day, s.c). All treatment drugs were administered for 16 days after induction of Parkinson rat's model. Sitagliptin and liraglutide were administered in three different dose levels (10-20-30 mg/kg, p...

Radiotherapy is one of the most relevant treatment options for cancer therapy with or without other treatment modalities including immunotherapy, surgery and chemotherapy. Exposure to heavy doses of ionizing radiation during radiotherapy results in short and long term side effects. It appears that many of these side effects are linked to inflammatory responses during treatment or after prolonged use. Inflammation is mediated by various genes and cytokines related to immune system responses caused by massive cell death following radiotherapy...

Our previous studies have indicated that osthole may ameliorate the hepatic lipid metabolism and inflammatory response in nonalcoholic steatohepatitic rats, but the underlying mechanisms remain unclear. This study aimed to determine whether the effects of osthole were mediated by the activation of hepatic peroxisome proliferator-activated receptor α/γ (PPARα/γ). A rat model with steatohepatitis was induced by orally feeding high-fat and high-sucrose emulsion for 6 weeks. These experimental rats were then treated with osthole (20 mg/kg), PPARα antagonist MK886 (1 mg/kg) plus osthole (20 mg/kg), PPARγ antagonist GW9662 (1 mg/kg) plus osthole (20 mg/kg) and MK886 (1 mg/kg) plus GW9662 (1 mg/kg) plus osthole (20 mg/kg) for 4 weeks...

Osteoporosis is a multifactorial and debilitating disease resulting from decreased bone mineral density (BMD) and loss of tissue microarchitecture. Ineffective therapies may lead to bone fractures and subsequent death. Single nucleotide polymorphisms (SNPs) in key immune regulator genes have been associated with therapeutic response to bisphosphonates, which are the first therapeutic line of choice for osteoporosis. However, cytokine pathways and their relation with therapeutic adhesion remain to be fully elucidated...

Jonas Kure Buer
The category of disease-modifying anti-rheumatic drugs (DMARDs) emerged in the 1970s to describe drugs capable of altering the long-term destructive course of arthritis. It became a core concept in rheumatology's reorientation towards pharmaceuticals in the late twentieth century. By examining the earliest use of the term "disease-modifying" in scientific publications, this paper identifies the drugs that the category described when it first emerged. Leaning on systematic reviews of each of these drugs towards the end of their career in rheumatology, it then establishes that posterity would not recognize any of these early DMARDs as capable of altering the long-term course of the disease...
