Wiley, New York, etc. Current Concepts in Nutrition Vol.1. 



X,245 pp., 58 figs., 36 tabs., subject index. £ 7.80 



Contents: 1. Development of physiological regulations; 2. En- 

 zyme development and nutrition; 3. Nutrition and cell growth; 

 4. Lipid metabolism and nutrition in the prenatal and postna- 

 tal periods; 5. Hormonal and dietary factors in the develop- 

 ment of digestion and absorption; 6. Metabolic changes in 

 children with protein-calorie malnutrition 



This book was written by an international team of experts: 

 five Americans, four Jamaicans, two Australians, and one Cana- 

 dian. All chapters are synthetic reviews and all deal with pre- 

 and postnatal mammals and man. The subject is discussed against 

 a broad biological background. 



Ch.l (by Adolph; 22 pp.) views the emergence of physiological 

 regulation in the fetus and neonate in a broad context and 

 serves as a theoretical introduction to the volume. Chs.3 and 5 

 are the longest (50 and 66 pp., respectively); the other chap- 

 ters range in length between 26 and 38 pages. 



As the various chapters were apparently not written at the 

 same time, their bibliographies are not equally up-to-date. Sev- 

 eral chapters contain much tabular material; the illustrations 

 are confined to graphs. The book is well produced.

Study of the effects of a single injection, on the 3rd day of 

 life, of ACTH or peptides derived from it, on somatic develop-

 behaviour patterns; evidence for a direct effect on CNS.
