Protective effect of clotrimazole on lung injury in an experimental model of ruptured abdominal aortic aneurysm.

Background: Lungs are the target organs most affected by ischemia/reperfusion (I/R) injury, which is exacerbated when hemorrhagic shock occurs. Suppressing various proinflammatory cytokines, inflammation and oxidation that initiate and aggravate lung damage with various drugs or methods provides significant benefits in preventing lung damage.

Objectives: This study aims to evaluate the protective effect of clotrimazole (CLT), an antimycotic drug, on lung injury and systemic inflammatory response in rats by creating an experimental model of a ruptured abdominal aortic aneurysm (RAAA).

Vanillic acid abrogates cisplatin-induced ovotoxicity through activating Nrf2 pathway.

Although cisplatin (CDDP) is an effective anticancer agent, the ovotoxicity that can occur in female patients limits its use. Oxidative stress (OS) and inflammation are known to contribute to CDDP-induced ovotoxicity. Vanillic acid (VA) is a dietary herbal secondary metabolite with high free radical scavenging activity.

Ethyl pyruvate attenuates cisplatin-induced ovarian injury in rats via activating Nrf2 pathway.
