In this comprehensive account of the history and treatment of beriberi, Kenneth Carpenter traces the decades of medical and chemical research that solved the puzzle posed by this mysterious disease. Caused by the lack of a minute quantity of the chemical thiamin, or vitamin B1 in the diet, beriberi is characterized by weakness and loss of feeling in the feet and legs, then swelling from fluid retention, and finally heart failure. Western doctors working in Asia after 1870 saw it as the major disease in native armed forces and prisons. It was at first attributed to miasms (poisonous vapors from damp soil) or to bacterial infections. In Java, chickens fed by chance on white rice lost the use of their legs. On brown rice, where the grain still contained its bran and germ, they remained healthy. Studies in Javanese prisons then showed beriberi also occurring where white (rather than brown) rice was the staple food. Birds were used to assay the potency of fractions extracted from rice bran and, after 20 years, highly active crystals were obtained. In another 10 years their structure was determined and "thiamin" was synthesized. Beriberi is a story of contested knowledge and erratic scientific pathways. It offers a fascinating chronicle of the development of scientific thought, a history that encompasses public health, science, diet, trade, expanding empires, war, and technology. From the preface: This is a medical detective story: beginning with the investigation of a disease that has killed or crippled at least a million people, and then following up clues that ranged much wider. One outcome was the production of a synthetic chemical that we now, nearly all of us, consume in small quantities each day in our food. The detectives had a variety of professions and spoke different languages. Their work ranged from studying the health of laborers in a primitive jungle to the painstaking dissection of individual grains of rice under a microscope. The integrated story of their struggles and successes, culled from old volumes in scattered libraries, forms the subject of this book.

The term ""vitamine"" was first used 101 years ago in 1912. What were later to be known as vitamin-deficiency diseases, such as scurvy, beriberi, night blindness, xeropthalmia, pellagra, pernicious anemia and rickets, had plagued the world since the existence of written records. The book contains 10 chapters and traces each vitamin from an unidentified factor to its discovery and synthesis.

Biology as a subject not only plays a major role within the scientific world but has broader implications that cross many boundaries. This work takes a modern and innovative approach to teaching introductory biology; it presents fundamental biological concepts within the context of current social issues. How do scientists affect our society at large? How are ethics and morals applied to the scientific world? Why are we racing to complete the human genome project, and who are we racing against? How do economic disparities between people and nations influence habitat destruction? Can plant science feed the world? Are the causes of cancer more genetic or environmental? The book seeks to help students think critically about these questions and to explore and assess the role that science plays in their world.
