Modulation of Immunological, Biochemical, and Histopathological Changes of Airway Remodeling by Withania somnifera in an Experimental Model of Allergic Asthma in Rats.
Objectives: Airway remodeling in asthma involves chronic inflammation associated with structural changes, which result in severe airflow limitation and very few therapeutic options. Thus, the present study was designed to experimentally evaluate the ameliorative effects of Withania somnifera (WS) root extract against Ovalbumin (OVA)-induced airway remodeling in a rat model of asthma.
Methods: Wistar rats were immunized (i.p) and challenged (aerosol) with ovalbumin (OVA), and the effects of WS extract were investigated on the development and progress of airway remodeling by assessing immunological, biochemical, and histological changes in these rats.
Results: OVA-immunization and challenge in rats resulted in significant increases in the levels of IL-13, 8-OhdG, TGF-β, hydroxyproline, and periostin in bronchoalveolar lavage fluid (BALF) and serum/lung homogenate compared to normal control (saline only) rats, and these changes were attenuated after WS extract (200 and 400 mg/kg), as well as dexamethasone (DEX, 1 mg/kg) pretreatments. Further, WS extract attenuated histopathological changes and maintained lung integrity. In herb-drug interactions, sub-threshold doses of WS extract and DEX showed synergistic effects on all parameters studied as compared to either form of monotherapy.
Conclusion: These results indicated that WS exerted significant protective effects against airway remodeling in the experimental model by modulating inflammatory and fibrotic cytokines, and could have the potential for developing a therapeutic alternative/adjunct for the treatment of airway remodeling of bronchial asthma.
期刊介绍：
The Journal of Pharmacopuncture covers a wide range of basic and clinical science research relevant to all aspects of the biotechnology of integrated approaches using both pharmacology and acupuncture therapeutics, including research involving pharmacology, acupuncture studies and pharmacopuncture studies. The subjects are mainly divided into three categories: pharmacology (applied phytomedicine, plant sciences, pharmacology, toxicology, medicinal plants, traditional medicines, herbal medicine, Sasang constitutional medicine, herbal formulae, foods, agricultural technologies, naturopathy, etc.), acupuncture (acupressure, electroacupuncture, laser acupuncture, moxibustion, cupping, etc.), and pharmacopuncture (aqua-acupuncture, meridian pharmacopuncture, eight-principles pharmacopuncture, animal-based pharmacopuncture, mountain ginseng pharmacopuncture, bee venom therapy, needle embedding therapy, implant therapy, etc.). Other categories include chuna treatment, veterinary acupuncture and related animal studies, alternative medicines for treating cancer and cancer-related symptoms, etc. Broader topical coverage on the effects of acupuncture, the medical plants used in traditional and alternative medicine, pharmacological action and other related modalities, such as anthroposophy, homeopathy, ayurveda, bioelectromagnetic therapy, chiropractic, neural therapy and meditation, can be considered to be within the journal’s scope if based on acupoints and meridians. Submissions of original articles, review articles, systematic reviews, case reports, brief reports, opinions, commentaries, medical lectures, letters to the editor, photo-essays, technical notes, and book reviews are encouraged. Providing free access to the full text of all current and archived articles on its website (www.journal.ac), also searchable through a Google Scholar search.
