E.J.HAWRYLEWICZ and B. P. CHOW, eds. 1971. THE RELATIONSHIP OF 



PERINATAL MALNUTRITION TO BRAIN DEVELOPMENT 



Geron-X, Los Altos. Nutr . Rep . Int . Vol.4, no. 5. 84 pp., 7 figs. 



20 tabs., no Indexes 



This special issue contains nine papers p^pepared for a Confer- 

 ence planned for May 1971, which for unforeseen reasons was 

 never held. All papers are Dy American authors. 



Among the subjects discussed are the following: placental bio- 

 chemistry and intra-uterine nutritional status; fetal undernour- 

 ishment and postnatal growth potential; prenatal dietary or ca- 

 loric restriction and postnatal cerebral cell number and compo- 

 sition; prenatal protein restriction and mitochondrial function 

 in the postnatal brain.

These volumes embody the proceedings of the third of a series 

 of five-yearly Symposia on immunology held in Prague. The Sympo- 

 sium was held in June, 1969 and was organized by the Department 

 of Immunology, Institute of Microbiology, Czechoslovak Academy 

 of Sciences. It was attended by nearly 100 scientists from all 

 parts of the world. The editors write in their preface: "The 



subject of the present symposium seemed to the organizers 



to express the prevailing trend in theoretical immunology in the 

 five past years: the manner in which immune mechanisms develop 

 in stages under natural selective pressures." 



It is impossible to mention all those among the 68 papers 

 which might be of interest to our readers. Instead, we will list 

 the significant papers in sections 1 (vol.1) and 8 (vol.11; see 

 above). Section 1 has a paper by Auerbach on his germinal theory 

 of Immunity, and papers by Kruml et al. on the development of 

 lymphatic tissue, by Weissman on the role of the thymus and ex- 

 trathymic factors In the development of immune competence, and 

 by Silversteln and Prendergast on lymphogenesis, immunogenesis , 

 and the generation of immunological diversity. Section 8 has pa- 

 pers by Dreyer on a new chromosomal control mechanism for com- 

 mitment of specific cell lines during development, by Hood and 

 Talmadge on the basis of antibody diversity in relation to the 

 germinal theory, and by Jilek and Sterzl on a model of dltleren-
