❓ Important Questions and Answers
Q1. What is the most critical mediator of Ischemia Reperfusion Injury?
Ans. Reactive Oxygen Species (ROS), particularly superoxide and hydrogen peroxide, are key mediators.
Q2. Why does reperfusion cause more damage than ischemia alone?
Ans. Reintroduction of oxygen leads to ROS formation, calcium influx, and inflammation that surpasses ischemic damage.
Q3. Name one clinical scenario where IRI is commonly observed.
Ans. During myocardial infarction treatment using thrombolytics or angioplasty.
Q4. Differentiate between ischemic and reperfusion damage at the cellular level.
Ans. Ischemic damage leads to ATP depletion, while reperfusion damage adds oxidative stress, inflammation, and membrane injury.
🔍 Fast Facts on Ischemia Reperfusion Injury
- ⚡ ROS are the villains—but neutrophils are their sidekicks.
- 🧬 Mitochondria are the first to be affected by oxidative stress.
- ❤️ In myocardial infarction, most cell death occurs after blood flow is restored.
- 💉 In transplant surgery, minimizing IRI is key to graft survival.
- 🧊 Hypothermia reduces IRI by slowing metabolic reactions.
