Abstract

Background: Jasminum humile is widely used in traditional medicines to treat hard lumps, mouth inflammation, ringworms, and other infections. Leaf decoction of the plant is known to be effective in treating various skin conditions. In addition, root juice is traditionally utilized as a remedy for ringworm infections. Studies have reported that J. humile contains various antioxidant metabolites with analgesic and anti-inflammatory properties. In this study, J. humile chloroform extract (JHC) was investigated for anti-inflammatory effects against carrageenan-induced paw oedema in rat models.

Methods: High-performance liquid chromatography was used to examine phenolic compounds present in JHC. The in-vivo anti-inflammatory activities were investigated using carrageenan-induced paw oedema rat models, while indomethacin was referred to as positive control. Therapeutic properties of JHC were examined by assessing paw volumes, motility score, and inflammatory proteins in serum. The anti-inflammatory nature of JHC was further investigated by biochemical and hematological profiles along with genetic expression of inflammatory and antioxidant genes through qRT-PCR analysis.

Results: Indomethacin at 10 mg/kg and JHC at 100, 200, and 300 mg/kg doses decreased the concentration of C-reactive protein (CRP) while upregulating the concentration of albumin and myeloperoxidase (MPO). Moreover, JHC administration reduced the expression levels of inflammatory markers, cyclooxygenase-2 (COX2), and inducible nitric oxide synthase (iNOS) compared to the Carr-treated control. However, a significant rise was induced in nuclear factor erythroid 2-related factor 2 (Nrf-2) and heme oxygenase 1 (HO-1) levels after JHC treatment as compared to Carr-treated rats.

Conclusion: These results showed significant anti-inflammatory potential of J. humile by increasing the activity levels of enzymatic antioxidants and lowering inflammatory markers. These results confirm the beneficial use of natural plants in the development of new anti-inflammatory drugs.

期刊介绍： Inflammopharmacology is the official publication of the Gastrointestinal Section of the International Union of Basic and Clinical Pharmacology (IUPHAR) and the Hungarian Experimental and Clinical Pharmacology Society (HECPS). Inflammopharmacology publishes papers on all aspects of inflammation and its pharmacological control emphasizing comparisons of (a) different inflammatory states, and (b) the actions, therapeutic efficacy and safety of drugs employed in the treatment of inflammatory conditions. The comparative aspects of the types of inflammatory conditions include gastrointestinal disease (e.g. ulcerative colitis, Crohn''s disease), parasitic diseases, toxicological manifestations of the effects of drugs and environmental agents, arthritic conditions, and inflammatory effects of injury or aging on skeletal muscle. The journal has seven main interest areas: -Drug-Disease Interactions - Conditional Pharmacology - i.e. where the condition (disease or stress state) influences the therapeutic response and side (adverse) effects from anti-inflammatory drugs. Mechanisms of drug-disease and drug disease interactions and the role of different stress states -Rheumatology - particular emphasis on methods of measurement of clinical response effects of new agents, adverse effects from anti-rheumatic drugs -Gastroenterology - with particular emphasis on animal and human models, mechanisms of mucosal inflammation and ulceration and effects of novel and established anti-ulcer, anti-inflammatory agents, or antiparasitic agents -Neuro-Inflammation and Pain - model systems, pharmacology of new analgesic agents and mechanisms of neuro-inflammation and pain -Novel drugs, natural products and nutraceuticals - and their effects on inflammatory processes, especially where there are indications of novel modes action compared with conventional drugs e.g. NSAIDs -Muscle-immune interactions during inflammation [...]
