I found an article in the Am.J.of the Medical Sciences--Apr. 1956 entitled "Induced Azotemia in Humans Following Massive Protein and Blood Ingestion and the Mechanism of Azotemia in GI Hemorrhage." The author gave "normal volunteers--5 healthy male physicians" (I think residents in his program) A.800 cc whole human blood via Levine tube, B. Liquid protein concentrate a week later, and C. Beefsteak (I guess this was their "reward"). He measured BUN after each of these interventions and found it went up with all. I don't think one could do that kind of study these days. Hope this is helpful. I'm a nephrologist in practice (fellow 1978-80). Nathan Hellman's Dad and I were residents together.
