Abstract

Oxidative stress plays a key role in the immunopathogenesis of asthma. The objective of this study was to investigate the thymol effects on oxidative parameters along with trace elements in asthma experimental model. The Balb/c mice were sensitized by intraperitoneal injection of ovalbumin and thymol (8, 16 and 32 mg/kg) and dexamethasone (DEX) (2 mg/kg) were orally administered to sensitized mice. Oxidative stress parameters including protein carbonyl content, malondialdehyde (MDA), 8-hydroxy-2'-deoxyguanosine (8-OHdG) and total antioxidant capacity (TAC) besides trace element levels were evaluated. The protein carbonyl content, MDA and 8-OHdG in treated mice with 32 mg/kg of thymol significantly decreased compared to asthmatic mice (P < 0.01). Also, TAC significantly increased (P < 0.001) as well as zinc and selenium levels while copper level decreased. 16 mg/kg of thymol reduced the protein carbonyl content, MDA and 8-OHdG compared to asthmatic mice (P < 0.05). In addition, thymol improved the most prominent inflammation characteristics of asthma. The obtained results suggest that thymol has a protective effect against oxidative stress and it was also able to partially restore the defective trace element levels in asthma.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
