      Recent Advances in Animal Nutrition — 1987 focuses on the advancement of techniques, procedures, and processes in animal nutrition. The selection first discusses techniques for identifying the metabolizable energy (ME) content of poultry feeds and the impact of declaration of ME value of poultry feeds. Methods for determining the ME of feeds; formulation of products and declaration of energy; species and ages of birds; and analytical problems are considered. The book also discusses the effects of diarrhea and wet litter in meat poultry; the inclusion of phosphorus in the diet of laying hens; natural products for egg yolk pigmentation; and the addition of enzymes to enhance the utilization of pig and poultry diets. The text also examines the nutrition of goats and cattle; immunity, nutrition, and performance in animal production; and methods of identifying the amino acid requirement of pigs. The book highlights as well the reactions of consumers to meat quality. Consumption trends; changes in eating patterns, retailing, and consumer purchasing patterns; and fatness and eating quality are considered. The book is a good source of information for readers wanting to study animal nutrition.

      The Living Barrier: A Primer on Transfer across Biological Membranes provides information pertinent to the movement of molecules across cell membranes. This book covers a variety of topics, including cell membrane, membrane transfer, water transfer, and movement of charged solutes. Organized into nine chapters, this book begins with an overview of the basic ideas of the cell membrane and reviews the experimental evidence about the structure of the cell membrane. This text then reviews the classical electron microscope pictures of membranes. Other chapters consider the interactions between electrical potentials and the movements of charged substances, which make the membrane transfer of these substances much more complicated than those of neutral molecules. This book discusses as well the aspects of water structure and its influence on membrane permeability. The final chapter deals with the methods by which membranes are synthesized. This book is a valuable resource for biochemists, physiologists, pharmacologists, and botanists.

      Drug Therapy During Pregnancy is a collection of papers dealing with the risks and benefits of drug treatment for both mother and fetus. One paper notes that the total use of medication during pregnancy in the Netherlands has decreased from 82.7 % to 71.7 %. The paper also points out the lack of a relationship between the number or type of congenital anomalies and the use of medication. Another paper assesses fetal drug exposure in two ways: firstly, through the physicochemical characteristics of the drug and the way it is handled by the mother in order to estimate placental passage and fetal exposure. Secondly, through the utilization of pharmacokinetic models estimating the probable time course of drug concentrations in the feto-maternal unit. One paper investigates the effects of hypertension during pregnancy, in which the etiology of hypertension, a group of disorders with one common abnormality, remains unsolved with a clinical diagnosis that is not always accurate. Treatment differs widely depending on the type: chronic hypertension, albuminuric hypertension, and hypertensive crises during pregnancy. One paper suggests that to prove any environmental exposure to a particular substance affecting pregnancy, the exact timing of exposure must be established, large samples are necessary, possibly on a national or international scale. The paper cites as example the four-year documentation period of the 50% to 80% incidence of malformations due to thalidomide. General medicine practitioners, obstetricians, gynecologists, and researchers dealing with pharmacology, pharmocokinetics, toxicology, or embryology will find the collection valuable.
