The effects of amiodarone in ovarian injury due to oxidative stress and inflammation caused by ischemia-reperfusion.

Objective: Ovarian ischemia constitutes 2-3% of all gynecological emergencies. New-generation therapeutic agents need to be discovered, in addition to invasive interventions capable of reducing the risk of potential ovarian ischemia to a minimum and protecting against potential adverse outcomes.

Aims: To investigate the effects of amiodarone (AMD) on ischemia-reperfusion-induced oxidative stress and inflammation-induced ovarian damage.

The protective effects of trimetazidine against ovary ischemia-reperfusion injury via the TLR4/Nf-kB signal pathway.

Late diagnosis and treatment of ovarian ischemia can lead to worsening of ischemia, irreversible damage to ovarian functions and infertility. In this process, there is no approved medical treatment that can reduce the negative effects of ischemia and contribute positively to ovarian functions during reperfusion after detorsion. Rats were randomly assigned into one of six groups of eight animals each.

The effects of vitamin B12 on the TLR-4/NF-κB signaling pathway in ovarian ischemia-reperfusion injury-related inflammation.

Ovarian ischemia is a gynecological emergency case that occurs as a result of ovarian torsion. Oxidative stress and inflammation play central roles in the development of ischemia/reperfusion injuries. We investigated the effects of Vitamin B12, thought to possess antioxidant characteristics on oxidative stress and the toll-like receptor 4 (TLR-4)/nuclear factorkappa B (NF-κB) signaling pathway in the ovaries during ischemia-reperfusion.

Nitric oxide synthase inhibition in rats: melatonin reduces blood pressure and ischemia/reperfusion-induced infarct size.

Reduction in the synthesis or bioavailability of nitric oxide plays a significant role in the development of myocardial infarction and hypertension. Numerous studies suggest that melatonin reduces blood pressure (BP) and ischemia/reperfusion (I/R) injury in rats. The effects of melatonin on the BP and I/R-induced cardiac infarct size in L-NAME-induced hypertensive rats remains unknown.

[Myocardial ischemia-reperfusion injury and melatonin].

It is believed that myocardial ischemia-reperfusion injury is related to increased free radical generated and intracellular calcium overload especially during the period of reperfusion. The pineal secretory product, melatonin, is known to be a potent free radical scavenger, antioxidant and can inhibit the intracellular calcium overload. In this review, we have summarized the fundamental of cardiac ischemia-reperfusion injury and the effects of melatonin on myocardial damage that related to cardiac ischemia-reperfusion injury.

Melatonin attenuates renal ischemia-reperfusion injury in nitric oxide synthase inhibited rats.

Recent studies show that melatonin reduces the blood pressure (BP) and ischemia/reperfusion (I/R)-induced damage. This study was designed to investigate the effects of melatonin on the renal I/R injury in rats given the nitric oxide synthase (NOS) inhibitor, N(omega)-nitro-L-arginine methyl ester (L-NAME). After right nephrectomy, I/R was induced by occlusion of the left renal vessels for 60 min, followed by 24h reperfusion.
