  • The Status of Enzymes and Hormones in Therapy

    • 1st Edition
    • G. F. Walker
    • English
    The Status of Enzymes and Hormones in Therapy reviews the status of therapy with enzymes and hormones, with emphasis on endocrine preparations of thyroid and parathyroid, ovarian hormones, pituitary hormones, thymus, and suprarenal glands as well as testis, spleen, brain and muscle tissue, and other organs such as the bile and placenta. The landmarks used are the British Pharmacopoeia, the British Pharmaceutical Codex published in September 1934, and clinical records selected from the literature. Comprised of two chapters, this book begins with an introduction to endocrine therapy, focusing on the need for clinicians to properly assess the clinical potency of the remedies they use based on considerations such as whether they clearly recognize in their patient a hormonic lack, or whether the preparation is smoothly active when administered by the route they propose. The second chapter deals with various endocrine preparations, including commercial preparations of thyroid; ovarian and pituitary hormones; stomach; pancreas; bone marrow; hemoglobin; and pineal, mammary, lymphatic, and prostate glands. This monograph is intended for clinicians interested in the therapeutic uses of enzymes and hormones.

  • Chemical Determinations

    • 1st Edition
    • Ralph I. Dorfman
    • English
    Chemical Determinations is a collection of papers that discusses chemical methods used in hormone investigation. One paper explains the physicochemical procedures used to separate estrogens from interfering material which leads to the possible determination of small amounts of hormones in biological fluids. One approach is through simpler methods for routine use, designed principally for the determination of estrogens in urine and in plasma. Another way is through more elaborate methods, designed to establish the presence and identity of various estrogens in small numbers of biological samples. Another paper explains the methods for the analysis of 17-ketosteroids of blood and urine, and a method for the assay of testosterone in plasma which correlates with the state of virilism of an individual. One paper describes the techniques utilized for extraction, preliminary purification, isolation, and quantitative estimation of progesterone. Another paper reviews the occurrence of pregnanetriolone (an inactive urinary metabolite), the significance of its estimation as an aid in differential diagnosis, the methods of estimation, as well as the metabolic pathways leading to the excretion of pregnanetriolone and related steroids. The collection is suitable for researchers, scientists, medical practitioners, or academicians involved in endocrinology, metabolism, and bio-research.
