Abstract:

Abstract Aims: To investigate the effect of Myrtenol, the active ingredient of Myrtle, on the oxidant and anti-oxidant indices and cytokines in the allergic asthma. Methods: Allergic asthma was induced by ovalbumin (OVA) sensitization and inhalation in four groups of rats; Control, Asthma, Asthma+Dexamethasone and Asthma+Myrtenol. Myrtenol (50mg/kg) or Dexamethasone (2.5mg/kg) was administered intraperitoneally for 7 consecutive days after OVA inhalation. At the end, histopathological parameters and interleukins (Interleukin-10 (IL10), Interferon gamma (IFN-γ) , interleukin-1β (IL-1β), Tumor Necrosis Factor α (TNF-α)) and oxidative stress biomarkers, Malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GPX) in the lung and serum were measured by hematoxylin & eosin staining and ELISA method respectively. Results: Myrtenol reduced the pathological changes in the lungs and airway endothelium (P<0.01), (P<0.5). The level of IL-1β (P < 0.05) and MDA in the serum and lung tissue (P < 0.01), (P < 0.05), and also the level of TNF-α (P < 0.05) in the lung tissue decreased in the Myrtenol group compared to the asthma group. Myrtenol increased the level of IL-10 ( P < 0.05) and the activity of GPX in the lung tissue and serum (P < 0.001). Conclusion: Myrtenol may improve asthma by increasing the ratio of antioxidants to oxidants and reducing the ratio of pro-inflammatory to anti-inflammatory interleukins in the lung. Myrtenol is presented as a potent herbal medicine ingredient for the treatment of asthma.

Anti-inflammatory and Anti-diarrheal Effects of Methanolic Extracts of Seeds and Peel of Nephelium longan Fruits in Rats

Herbal medicines are playing a vital role in the remedy of numerous diseases. Preliminary phytochemical screening of the methanolic extracts of seeds (MNLS) and peel (MNLP) of Nephelium longan revealed the presence of alkaloids, tannins and flavonoids. For antidairrheal screening, we have followed Castor-oil-induced method whereas to check anti-inflammatory property, we used carrageenan-iduced ...

Additive anti-allergic effects of anti-interleukin-33 and anti-Siglec-F treatments in a murine model of allergic asthma

BACKGROUND Anti-interleukin-33 (anti-IL-33) and anti-Siglec-F antibodies have potent anti-allergic effects on murine allergic asthma and rhinitis and induce eosinophil apoptosis. OBJECTIVE We aimed to determine whether post-sensitization with anti-IL-33/anti-Siglec-F treatments exhibited more potent effects compared to individual treatments in a murine allergic asthma model. MATERIAL AND ME...
