Abstract
Background: Asthma is a long-term inflammatory respiratory condition marked by alterations in the airways and an increase in inflammatory cell infiltration. It has been observed that Curcumin possesses immune-modulating, anti-inflammatory, and relaxing properties for smooth muscle in the airways. Salmeterol is believed to ease the smooth muscles of the airways. Objective: Swiss Albino mice were used in the research to examine the combination anti-asthmatic effects of Curcumin and Salmeterol in asthma produced by ova albumin and milk induced eosinophilia and leucocytosis. Methods: The mice received pre-treatment with Curcumin (10 mg/kg, 20 mg/kg intraperitoneally) as well as Salmeterol (5 mg/kg) after being stimulated with an Ovalbumin (OVA) challenge and milk. After the induction period, various hematological, biochemical, molecular (ELISA), and histological analyses were performed. Results: The findings demonstrated that the combined treatment decreased the animal’s overall leukocyte and eosinophil numbers in a manner that was dose-dependent. Additionally, the therapy reduced albumin and overall protein amount in serum, BALF and lung tissues, facilitated changes in haematological parameters, and reduced the rise of Th2 cytokines (IL-4, TNF-α, IL-13) levels that is induced by OVA in lungs and BALF, total IgE level in serum. The combined action of Curcumin and Salmeterol reduced OVA-induced inflammatory influx and ultrastructural abnormalities, according to histopathological evaluation. Conclusion: The findings of this investigation demonstrate that curcumin and salmeterol together possess anti-asthmatic effects through suppressing Th2 triggered immune response and possessing an anti-inflammatory effect and anti-allergic effect. Thus combination of treatments might be a novel technique for managing asthma.
