Current Topics in Experimental Endocrinology, Volume 2 covers major developments in the ever-expanding field of endocrinology. The book discusses the progress in cyclic nucleotide research; the hypothalamic control of the anterior pituitary hormone secretion-characterized hypothalamic hypophysiotropic peptides; and the pituitary-ovarian interrelationships in the rat. The text also describes the melatonin and the endocrine role of the pineal organ; the integration of the secretory control mechanisms for insulin, glucagon, and growth hormone; and the biological activity of somatomedin. The chemistry and physiology of parathyroid hormone, calcitonin, and vitamin d; and the physicochemical properties and activities of luteinizing hormone and human chorionic gonadotropin are also encompassed. Endocrinologists, physiologists, and students taking related courses will find the book invaluable.
