Excerpt from book: THE ORIGIN OF THE HORMONES. The internal secretions may also be classified according to their origin. The distinction is between (a) products of the chemistry of the organs which are simply the end-products of decomposition, i.e., the waste'or by-products of the process of metabolism; and (6) substances which are the outcome of a synthetic process. It would be wrong, however, to imagine that the true hormones are all included in the latter group. For, in many instances, it is just the products of decomposition formed during cell-activity which are the stimulating agents, by whose aid the function, not of the cells only, but of other tissues, is promoted and maintained. That form of activity which is usually ascribed to automatic irritation of the nervous centre, is not really automatic; it is in reality brought about by the agency of the products of cell- metabolism and by the vital processes of the protoplasm. Thus, in suffocation, the changes in the respiratory and cardiac activity, the spasms of the voluntary muscles, and the tonic contractions of the muscular tissue of the vessels, are due solely to over- irritation by the products of decomposition, an excessive quantity of which is circulating in the blood. The regulation of normal respiration, moreover, is due to the agency of chemical stimuli. Nervous irritation coming from the periphery is able to modify respiration, but is unable to regulate it. It is more probable that the so-called automatic irritation of the centre of respiration, is brought about by the effete products, formed during and by the activity of the tissues. According to Miescher, and there is good grounds for his view, the actual agent is carbonic acid (CO2), one of the end-products of oxidation. The fluctuating quantity of CO2 in the blood brings a...

Book Description
Excerpt from The Internal Secretory Organs: Their Physiology and Pathology The subject of the Internal Secretions, or Glandular Physio logy as it is sometimes called, is one which is destined to occupy the attention both Of physiologists and clinicians for a long time to come. The admirable manner in which the microbic theory of disease has been developed and pressed into practical employ ment has served completely to revolutionize the surgery, and profoundly to modify the medicine, of thirty years ago. But the truth Of the theory and the wonders which it has wrought leave unexplained certain problems in pathology which cry aloud for solution. Microbes do not explain gout, diabetes, Graves's disease or Hodgkin's disease, to mention but a few which inhabit the vast territory which remains to be conquered. Upon these and allied diseases the study of the internal secretions promises to throw some light. It has already illuminated myxoedema, acromegaly, Addison's disease, and some others, and the promise which it holds is as enticing and fascinating as its pursuit is baffling. The condition precedent of any real progress on the clinical side is an exhaustive study Of the physiological side. Professor Biedl's book supplies this in a painstaking and methodical man ner. It comprises all the work of an experimental kind which has been done in any country up to within a very recent date. It is for the most part content to leave that work to speak for itself, and does not unduly burden the reader with explanations, or mislead him with premature theories.
