Download or read book Gossypol written by Sheldon J. Segal and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The search for a reversible male contraceptive has centered upon the suppression of sperm production or sperm motility. Gossypol, a natural substance extracted from the cotton plant, appears to cause both of these effects. Its ability to reduce spermatogenesis in men is undeniable and has been demonstrated in both large studies in China and a smaller confirmatory study in Brazil. These investiga tions have revealed the remarkable fact that with gossypol, it is possible to separate an effect on the testis' gamete-producing function from an effect on its hormone-producing function. Thus, it is possible to maintain normal testosterone levels and libido while sperm counts (and motility) fall. Because of this unique and important action, gossypol warrants the fullest possible evaluation as a potential male contraceptive. Sheldon J. Segal vii ACKNOWLEDGMENT Lynn C.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive treatise offers an in-depth discussion of natural toxicants in plants, emphasizing their effects as defenses against herbivory. Coevolution of plants and her-bivores are covered with a detailed treatment of toxicant metabolism and systemic effects in mammalian tissues. Con-sideration of the economic importance of plant toxins, modi-fication by plant breeding, management of toxico-sis, and toxicant problems in various geographic areas are in-cluded.

Download or read book Handbook of Plant and Fungal Toxicants written by J. P. Felix D'Mello and published by CRC Press. This book was released on 2020-03-27 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1997. Natural toxicants are the subject of research throughout the world, and they are used for many purposes. The Handbook of Plant and Fungal Toxicants presents a wide range of compounds and considers how they relate to food safety, therapeutic purposes in medicine, and uses in breeding plants for enhanced resistance to insects and disease. Alkaloids, both from plant and fungal sources, are emphasized. Also covered are a variety of toxicants and phytochemicals including: bracken fern poisons polyphenolics gossypol flavones isoflavones pyrimidine glycosides fruit and vegetable allergens linear furanocoumarins photosensitizing agents nitrates oxalates Pinus ponderosa toxicants The text stresses the positive aspects of plant secondary compounds and presents examples of beneficial attributes in the context of environmental protection and human health. An international authorship addresses the global diversity and ecological distribution of plant and fungal toxicants. This handbook is ideal for senior-level college students and post-graduate students studying animal science, toxicology, and pharmaceutical sciences.
