Inflammatory bowel disease (IBD) is a relapsing inflammation of intestine, which is mediated by release of inflammatory mediators. Both cyclo-oxygenase product prostaglandin (PGE2) and lipo-oxygenase product leukotriene (LTB4), may contribute to the pathogenesis of the inflammatory response. Nimesulide, a preferential COX-2 inhibitor was evaluated for its(More)
Inflammation processes may play a critical role in the pathogenesis of the degenerative changes and cognitive impairments associated with Alzheimer's disease (AD). Non-steroidal anti-inflammatory drugs are reported to be effective in reducing the risk of developing AD or cognitive impairments. Present experiments were performed to study the possible effect(More)
Tizanidine, an alpha2-adrenergic receptor agonist with myospasmolytic action, is indicated for the treatment of back pain either as monotherapy or in combination with nonsteridal anti-inflammatory drugs (NSAIDs). Tizanidine (0.25-1.0 mg/kg) significantly produced analgesic and anti-inflammatory effect in acetic acid induced writhing in mice and(More)
Diamond-like carbon films have been evaluated as coatings to improve biocompatibility of orthopedic and cardiovascular implants. This study initiates a series of investigations that will evaluate diamond-like carbon (DLC) as a coating for improved biocompatibility in chronic neuroprosthetic implants. Studies in this report assess the cytotoxicity and cell(More)
In human body ascorbic acid plays an essential role in the synthesis and function of skeletal tissues and immune system factors. Ascorbic acid is also a major physiological antioxidant, repairing oxidatively damaged biomolecules, preventing the formation of excessive reactive oxygen species or scavenging these species. We recently reported the synthesis of(More)
Various evidence has demonstrated a role of the nitric oxide (NO)/cGMP signaling pathway in the processing of nociception. The exact role of phosphodiesterase-5 (PDE-5) via the NO/cGMP pathway is not fully understood in pain response. The aim of the present study was to investigate the possible peripheral interaction between a PDE-5 inhibitor (sildenafil)(More)
Selective serotonin reuptake inhibitors (SSRIs) have been used clinically as co-analgesics in various devastating painful conditions. Upon chronic treatment tolerance develops to their analgesic effect, which is often refractory to increasing dose. Although modulation of serotonergic pathways considerably explains their clinical efficacy, numerous reports(More)
The current study was designed to evaluate the ameliorative effect of the cinnamon oil upon early stage diabetic nephropathy owing to its antioxidant and antidiabetic effect. Cinnamon oil was extracted by hydro-distillation of the dried inner bark of Cinnamomum zeylanicum Blume. Further characterization of the extracted oil was carried out using IR,(More)
Non-steroidal anti-inflammatory drugs (NSAIDs) and opioids are the most commonly used analgesics in the management of acute and chronic pain. Combined use of NSAIDs and opioids has been indicated for achieving better analgesia with reduced side effects. The present study was aimed at evaluating the combination of different NSAIDs, which inhibit(More)
Flavonoids, naturally occurring polyphenolic compounds, are known to inhibit both lipopolysaccharide (LPS) stimulated tumor necrosis factor alpha and interleukin 6 release which modulate the proinflammatory molecules that have been reported in many progressive neurodegenerative disorders, including Alzheimer's disease (AD), viral and bacterial meningitis,(More)
