This study will evaluate the safety profile and pharmacokinetic behavior of a single administration of Aerucin in healthy adults at three different dosages.

This Phase I trial will be conducted as an open label trial in 15 healthy adults. All subjects will receive a specific intravenous dose of Aerucin. There are three study groups, each with a specific dose of Aerucin. Study Group 1 will receive 2.0 mg/ kg of Aerucin . Study Group 2 will receive 8.0 mg/kg of Aerucin . Study Group 3 will receive 20 mg/kg of Aerucin . The dose levels of Aerucin are selected for this study based on animal studies showing protection in an animal model and absence of adverse effects in toxicological studies. Groups will be enrolled sequentially.

4. Abnormal urinalysis that, in the opinion of the investigator, is clinically significant
5. Positive screening urine test for illicit drugs (opiates, cocaine, amphetamines)
6. Has received an immunoglobulin product in the 120 days prior to Study Day 0
