and additional samples were drawn 15, 30, 50, 70, 145, 205, 2605, and 340 min after 
ingestion of glutamine. One feature of the study of patient H. Bie. was unique. At 
the time glutamine was ingested, a saline infusion was begun in the antecubital vein

infused . Thus, the two control samples were taken prior to the saline infusion, and 
the infusion was stopped 20 min after the 70 min post-ingestion sample was obtained.
