Trials in the treatment of the leukemias are sometimes based on a hypothesis, as in the case of exchange transfusion [33] or the use of antimetabolites [86]. Or they are conducted empirically as the results of chance observations, as in the case of the use of the nitrogen mustards, urethane, and the Vinca alkaloids. Or they lie between the two, aiming at making use of well established biological facts: examples are the use of ACTH, cortisone and, more recently, the antibiotics. What is true for bacteria may also perhaps be true, if not for elephants, at least for the malignant cells of mammals. It was this idea that lay behind the first attempts at treating cancer and leukemia with antibioti...
Normal and Malignant Cell Growth is a compendium of papers from the "Proceedings of the Third Cancer Training Grant" of the University of Chicago that deals with the processes associated with malignant neoplasia, as well as the cell proliferation kinetics of normal tissues. One paper presents the techniques used in the study on the proliferation kinetics of hemopoietic stem cells, suggesting that the hemopoietic stem cell population is not homogenous but consists of a "primitive pluripotential stem cell." A series of experiments at the Brookhaven National Laboratory investigates the relationship of cell survival, specifically that of stem cells, to the survival of the irradiated test animal....
Saponins are complex molecules made up of sugars linked to a triterpenoid or a steroid or a steroidal alkaloid. These natural products are attracting much attention in recent years because of the host of biological activities they exhibit. The diversity of structural features, the challenges of isolation because of their occurrence as complex mixtures, the pharmacological and biological activities still to be discovered, and the prospect of commercialization - these all are driving the study of saponins. Triterpenoid saponins are dominating constituents of this class and occur widely throughout the plant kingdom including some human foods e. g. beans, spinach, tomatoes, and potatoes, and ani...
Over the past two decades a number of attempts have been made, with varying degrees of success, to collect in a single treatise available information on the basic and applied pharmacology and biochemical mechanism of action of antineoplastic and immunosuppressive agents. The logarithmic growth of knowledge in this field has made it progressively more difficult to do justice to all aspects of this topic, and it is possible that the present handbook, more than four years in preparation, may be the last attempt to survey in a. single volume the entire field of drugs em ployed in cancer chemotherapy and immunosuppression. Even in the present instance, it has proved necessary for practical reason...
Doxorubicin: Anticancer Antibiotics details the development of doxorubicin as a wide-spectrum antitumor antibiotic. The book begins by tracing the discovery and development of doxorubicin, highlighting factors such as (a) the involvement of organic chemistry at an early stage, which allowed the rapid identification of doxorubicin and ensured its prompt availability for the clinical trials; (b) the well-established, pioneering expertise in experimental chemotherapy of Professor Aurelio di Marco and his group at Istituto Nazionale Tumori, Milan; and (c) the highly motivated interest of experienced clinicians. The remaining chapters provide an overview of basic studies in the area of medicinal chemistry and related fields that have resulted from doxorubicin development. Such studies have been concerned with both biochemical and biophysical investigations at the molecular level and at different levels of biological organization. A large body of work aimed at developing synthetic procedures for the drug and for new related analogs of potential clinical usefulness has also been carried out.
This first book to take a detailed look at one of the key focal points where nanotechnology and polymers meet provides both an introductory view for beginners as well as in-depth knowledge for specialists in the various research areas involved. It investigates all types of application for block copolymers: as tools for fabricating other nanomaterials, as structural components in hybrid materials and nanocomposites, and as functional materials. The multidisciplinary approach covers all stages from chemical synthesis and characterization, presenting applications from physics and chemistry to biology and medicine, such as micro- and nanolithography, membranes, optical labeling, drug delivery, as well as sensory and analytical uses.
Recent Results in Cancer Research: Bone Mineral Metabolism in Cancer presents the clinical approach to bone tissue metabolism, which depends on studying the plasma state, renal handling, kinetics, and balance of calcium and inorganic phosphate. This book discusses the problems of bone mineral metabolism in patients with cancer. Organized into five chapters, this book begins with an overview of the two major phases of bone mineral, namely, amorphous calcium phosphate and crystalline bone apatite. This text then examines the plasma state and renal handling of calcium and inorganic phosphate under controlled metabolic conditions. Other chapters consider the variability of each parameter in the majority of patients without bone secondaries. This book discusses as well the normal remodeling of bone in fertile-age women. The final chapter deals with the plasma state, renal handling, and kinetics of calcium and phosphate in plasmacytoma patients. This book is a valuable resource for oncologists.
This volume summarizes the proceedings of the fifth biennial Cancer Teaching Symposium held on March 4 and 5, 1972 at the University of Chicago Pritzker School of Medicine. The program was prepared by Drs. MELVIN GRIEM, ELWOOD JENSEN, HAROLD SUTTON, JOHN ULTMANN, and ROBERT WISSLER. The purpose of the symposium was to present the current status of the challenging cancer problem, breast carcinoma, to the staff and students of this medical center and to students and in terested physicians from other institutions in the Chicago area. In a fashion similar to the other teaching symposia held in 1964, 1966, 1968,. and 1970, this symposium attracted over 450 physicians and scientists. In the course...
The surgical resection of a major portion of the liver for cancer of this viscus has long been neglected. Although the first successful resection of a primary malignant tumor of the liver was performed by LUCKE in 1891, this pioneer effort failed to stimulate interest in the operative removal of hepatic neoplasms. Earlier surgeons were intimidated by the concept of the liver as a huge vascular sponge possessed of three intricate circulatory systems. To the fear of uncontrollable hemorrhage was added the supposed hazard of hepatic insufficiency following the removal of a large portion of an organ with so many vital functions. Last but not least was the difficulty in surgical exposure. Only in...
