22. "DIE PRANATALE INFEKTIONEN DES MENSCHEN. 



unter besonderer Beriicksichtigung 



von Pathogenese und Immunologie" 



1959 



by H. Flamm Georg Thieme Verlag 



136 pp., 2 figs. Price: D.M. 19.80 



This monograph brings together all data on prenatal infectious diseases and 

 their effects on the embryo and fetus. The subject matter is systematically 

 arranged according to the size of the infective organisms, ranging from the 

 viruses through the bacteria and fungi to the unicellular parasites and the 

 worms. A final chapter deals with the immunology of the prenatal and neo- 

 natal periods. 



The book is not illustrated. It contains a very extensive, systematically 

 arranged bibliography.

It is not necessary to evaluate the merits of a volume of the famous series 

 of Cold Spring Harbor Symposia. It will be sufficient to indicate why this 

 particular volume is of special interest to our readers. This is not immediately 

 apparent from the table of contents. The sessions were devoted to the role of 

 the genetic material as an information code in protein sythesis, to the 

 mechanism of information transfer from the genetic material to the site of 

 synthesis, and to cellular mechanisms governing the rates of enzyme activity 

 and enzyme synthesis. Most of the research presented dealt with micro- 

 organisms. However, the significance of this research for questions of normal 

 and abnormal growth and development in multicellular forms is apparent. This 

 is borne out in particular by the concluding paper by Monod and Jacob, which 

 is in a way a summing up of the entire symposium, and which bears the title 

 "Teleonomic mechanisms in cellular metabolism, growth, and differentiation". 

 This must be a stimulating article for every developmental biologist who tries 

 to think in molecular terms.

This book is written in Russian and is announced by title only. 



The book is in two parts, a special and a general one. In the former the 

 development of ten species belonging to ten different genera is discussed. 

 The book is illustrated mainly with hne drawings. The bibliography covers 

 ten pages, four of which are devoted to Russian papers.
