The numerous symposium papers cover many aspects of plasma protein work, including the physical and chemical nature of the serum proteins, their formation and biosynthesis and their relation to the dietary proteins, to hepatic function and to the immunochemical processes, the nature and occurrence of hypoproteinemia and its relation to anemia. The current critical international situation, with the great emphasis on plasma in the treatment of battle casualties, makes the discoveries elucidated in these papers even more meaningful. That various dietary protein sources may favor the filling of one body protein compartment over another constitutes a most important observation. A pronounced imbalance of amino acids in the diet can deplete one tissue while building up or maintaining another, especially if the imbalance is due to the presence of an amino acid with many functions, such as methionine. This book is highly informative and is strongly recommended.
