Radiological Analysis

Introduction: Cassia fistula has anti-inflammatory activity. Rheumatoid arthritis (RA) is an autoimmune disease, causing inflammation and disability of the affected joints. It is mostly treated symptomatically with NSAIDs, which themselves have a lot of adverse effects. In this study the anti-arthritic effect of Cassia fistula versus naproxen has been observed radiologically. Aims & Objectives: The present study was radiological analysis of anti-arthritic effect of Cassia fistula compared to naproxen in Complete Freund’s Adjuvant (CFA) induced rat model of rheumatoid arthritis. Place and duration of study: This study was conducted at the Animal House of University of Veterinary and Animal Sciences, Lahore for a period of three months. Material & Methods: The study was carried out on 96 male rats divided into 12 groups of 8 rats each. Single 0.2ml dose of Complete Freund’s Adjuvant (CFA) was injected in the right hind paw of each rat in all groups except Group 1 (negative control). Group 2 was positive control. The prophylactic (3-7) and therapeutic (8- 12) groups were given naproxen (25mg/kg), anthraquinone extract (250 &500mg/kg) or methanolic extract (250 & 500mg/kg) of Cassia fistula orally BD on days 1,2 &3 (first dose preceding CFA injection by 30 minutes) and on days 9,10 &11 for therapeutic groups respectively. On day 15, x-rays of right ankle joints of all groups were taken as a confirmatory investigation on the final status of the arthritis. Results: Our results showed both anthraquinone and methanolic extracts of Cassia fistula have dose dependent (500˃250mg/dl) prophylactic and therapeutic anti-arthritic potential albeit lesser than naproxen 25mg/kg, to reduce the swelling of hind paw and deformity of interphalangeal joints on radiological examination. Conclusion: The efficacy of Cassia fistula makes it a potential weaker candidate to naproxen in prevention and treatment of rheumatoid arthritis.

Heat Hyperalgesia

Vesicular glutamate transporter type 2 (VGLUT2) is known to play an important role in mediating heat hyperalgesia induced by inflammation. However, the underlying mechanism for this activity is poorly understood. Cyclin-dependent kinase 5 (Cdk5), serving as a key regulator in modulating release of glutamate, acted a key player in the formation of heat hyperalgesia of inflammatory pain. However, it remains unknown whether there is a bridge between Cdk5 and VGLUT2 for mediating inflammatory pain. Therefore, we designed the experiment to determine whether VGLUT2 signaling pathway is involved in inflammatory pain mediated by Cdk5 in the inflammatory pain model induced by complete Freund’s adjuvant (CFA). Our results showed that the coexpression of Cdk5/VGLUT2 in small- and medium-sized neuronal cells of the dorsal root ganglion (DRG) and spinal cord between days 1 and 3 following subcutaneous injection of CFA was significantly increased. Moreover, our study revealed that the expression of VGLUT2 protein in the DRG and spinal cord was remarkably increased between days 1 and 3 following CFA injection and was significantly reduced by roscovitine, a selective antagonist of Cdk5. Additionally, p25 but not p35, an activator of Cdk5, protein was significantly increased by CFA and reduced by roscovitine. Our findings suggested that VGLUT2/Cdk5 signaling pathway contributes to inflammatory pain mediated by Cdk5/p25.
