The book opens with a survey by Dr. Motron Cowan of biotin-responsive metabolic disorders of children. A group of Japanese researchers then present their latest data on the complex interactions between vitamin D and parathyroid hormone (PTH) in bone calcification. Dr. Maxine Briggs reviews the prolific published information relating vitramin C to infectious diseases and presents the results of an 8 year study into the prophylactic value of high-dose ascorbic acid (AA) and the common cold. Professor Kristoffersen and Dr. Rolschau review the effects of vitamin supplements during pregnancy and intrauterine growth. Possible protective effects of vitamin A and other retinoids against cancer are discussed by Dr. Jill Blunck, while Dr. Sue Tonkin describes her results on the interaction between oral contraceptives and riboflavin. Finally, the possible prevention of neural tube defects by vitamin supplements by Professor Laurence.
It is hoped that this collection of papers on the frontiers of vitamin research will be of wide interest to medical and scientific workers interested in the exciting and controversial used and functions of vitamins.
