Orally administered L-isoleucine, DL-isoleucine and L-leucine exhibited anti-inflammatory activity in many test models of inflammation except formaldehyde-induced inflammation. L-beta-phenylalanine inhibited carrageenan-induced oedema only. L-isoleucine also exhibited prolonged analgesic effect while DL-isoleucine had a short lasting effect. The amino-acids produced no gastric ulceration or ove...

BACKGROUND Chronic prostatitis/Chronic pelvic pain syndrome (CP/CPPS) is the most common type of prostatitis. Due to the lack of a suitable animal model partly, the pathogenesis for this condition is obscure. In the current study we developed and validated an animal model for nonbacterial prostatitis and prostate inflammation-induced chronic pelvic pain in rats with the use of intraprostatic in...

BACKGROUND The studies on the mechanisms of ketamine antinociception have led to conflicting results. In this study, the authors investigated the contribution of supraspinal monoaminergic descending inhibitory system to ketamine analgesia for acute nociception and inflammation-induced hyperalgesia. METHODS Male Sprague-Dawley rats were used. The paw withdrawal latencies to radiant heat stimul...

The pathophysiology of acute joint inflammation remains unclear. Evidence is available to suggest a neurally mediated component to the inflammatory process. Acute joint inflammation in the rat knee, induced by intra-articular injection of 2% carrageenan, was reduced by 44% in animals whose knee had previously been injected with 1% capsaicin, while chronic joint denervation produced a 37% reduct...

Introduction and Aim: Solanum pubescens is one of the very well-known traditional medicinal plants it has been widely used in treatment many inflammatory conditions. This study aimed to evaluate anti-inflammatory property S. fruit. Materials Methods: Anti-inflammatory activities fruit extracts at different concentrations (100-200 mg/kg) were carried out using carrageenan-induced cotton implant-...

diclofenac sodium has been used for its anti-inflammatory actions for about 28 years, but since all the non-steroidal anti-inflammatory drugs (nsaids) suffer from the lethal gastro intestinal (gi) toxicities, diclofenac sodium is not an exception. the free –cooh group is thought to be responsible for the gi toxicity associated with all traditional nsaids. in the present research, the main motto...

OBJECTIVE The roots of Chlorophytum borivilanum are used in traditional medicine for the treatment of arthritis and inflammation. The aim of the work was to evaluate the anti-inflammatory activity of isolated saponins from Chlorophytum borivilianum (ISCB). METHODS The ISCB was screened using the carrageenan-induced paw edema, histamine-induced paw edema, cotton pellet-induced granuloma, and F...

Disability and movement-related pain are major symptoms of joint disease, motivating the development of methods to quantify motor behaviour in rodent joint pain models. We used observational scoring and automated methods to compare weight bearing during locomotion and during standing after single joint inflammation induced by Freund's complete adjuvant (0.12-8.0 mg/mL) or carrageenan (0.47-30 m...

Increasing indication is unveiling a role for poly(ADP-ribose) polymerase (PARP)-1 in the regulation of inflammatory/immune responses. The aim of the present study was to determine the potential anti-inflammatory effects of PARP-1 inhibitor 5-aminoisoquinolinone (5-AIQ) to explore the role of PARP-1 inhibitor in a mouse model of carrageenan-induced lung inflammation. A single dose of 5-AIQ (1.5...

BACKGROUND Neonatal pain and inflammation may lead to a long-term effect on nociceptive processing in adults. The current study examined the characteristics of postoperative incisional pain behaviors in adult rats that were subjected to neonatal peripheral inflammation. METHODS Rat pups received a subcutaneous injection of saline or carrageenan into the plantar surface of the left hind paw at...
