Echium amoenum Hydroalcoholic Extract Effect on Oxidative Stress Due to Heat Stress in Rats

Among the biggest problems facing the world today are climate change and heat stress in the environment. It is crucial to look into these effects on various organisms. One of the most critical consequences of global warming is heat stress, which significantly disrupts the oxidative balance in living organisms by increasing reactive oxygen species (ROS) and reducing antioxidant capacity. This imbalance leads to cellular and tissue damage. Therefore, identifying effective strategies to reduce oxidative damage caused by heat stress is essential. One of the top priorities is to eradicate heat stress in living things. Plant extracts can significantly reduce heat stress by enhancing the immune system, improving effectiveness, and having few side effects. Residual medicinal plant extracts, such as Echium amoenum Fisch. & C.A.Mey., are known for their antioxidant properties. In this study, the protective effect of E. amoenum hydroalcoholic extract on oxidative stress induced by acute and chronic heat exposure in rats was investigated. Six groups of sixty rats were prepared. These groups include healthy control, sham, acute and chronic heat stress control stress groups (groups T۱ and T۲), group T۳: chronic heat stress conditions with daily injection of ۴۰۰ mg/kg body weight of the extract for ۲۱ days, and group T۴: acute heat stress conditions with daily injection of ۴۰۰ mg/kg body weight of the extract for ۲۱ days. Blood was taken from the rats under sterile conditions at the end of the study. The investigated parameters were measured using conventional techniques in the resultant sera. The findings demonstrated that prolonged exposure to heat significantly lowers serum catalase. All of the indicators that were examined catalase, vitamin D, superoxide dismutase, glutathione peroxidase, malondialdehyde, and total antioxidant capacity showed a noteworthy variation in response to acute heat stress in comparison to the control group. However, following the extract injection, a comparison of two heat stress groups and the control group demonstrated the extract's beneficial effects on stress reduction. In conclusion, the findings of this study showed that treatment with E. amoenum notably improves oxidative markers, especially under acute heat stress. This extract can alleviate oxidative damage caused by heat stress in rats.
