Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Oxygen is necessary for the survival of oxygen consuming organisms. But the organisms metabolism alter the oxygen to free radicals. Free radicals are molecules which due to their structure can react with other molecules resulting in cell damage. This damage is due to several mechanisms.

This is e.g what happens when human tissue is cut of from blood supply for a time, and the blood supply is again restored. The damage following the restoration of blood is known as "ischemia-reperfusion injury". The reopening of the vessels and thereby supplying oxygenated blood to the deprived tissue can in it self contribute to cell death due to excessive amounts of free radicals. Antioxidants can neutralize free radicals and thereby minimize their damage.

The purpose of the investigators methodology study is to make an ischemia-reperfusion model on healthy volunteers (on the lower limb) to examine the expression of markers that are expressed in the muscle and the blood when blood supply is cut of to an area and later restored. The investigators wish to measure the product of the damage caused by free radicals and the levels of antioxidants.

If the investigators can produce elevation of oxidative and inflammatory markers, this model can be used to test antioxidative intervention.
