Brief Summary
Ischemia reperfusion injury may be attenuated by HO-1 induction. Heme arginate showed protective effects during prolonged ischemia in animal studies. Functional blood oxygen level dependent (BOLD) magnetic resonance imaging (MRI) shall evaluate the effects of HO-1 induction during short-time ischemia in skeletal muscle of healthy subjects.

Eligibility Criteria
You may qualify if:
- Signed informed consent
- Men aged between 18 and 46 years (inclusive)
- Nonsmoker for more than 3 months
- Body mass index between 18 and 27 kg/m2

You may not qualify if:
- Known hypersensitivity to the study drug or any excipients of the drug formulation
- Regular use of medication, abuse of alcoholic beverages, participation in a clinical trial in the 3 weeks preceding the study
- Treatment with another investigational drug within 3 weeks prior to screening
- History or clinical evidence of any disease and/or existence of any surgical or medical condition, which might interfere with the absorption, distribution, metabolism or excretion of the study drug
- Evidence of hypertension, pathologic hyperglycemia, hyperlipidemia
- Treatment in the previous 3 weeks with any drug including over-the-counter drugs (including herbal medicines such as St John's Wort)
