The increased action of the muscles of the heart and the blood-vessels increases the efficiency of the circulation; the secretion of the adrenal gland causes a rise in the blood-pressure; the increased action of the thyroid gland causes an increased metabolic activity; there is evidence that glycogen is actively called out, this being the most immediately available substance for the production of energy; the increased activity of the respiration is needed to supply the greater need of oxygen and the elimination of the increased amount of waste products; the dilatation of the nostrils affords a freer intake of air; the increased activity of the sweat-glands is needed to regulate the temperature of the body which the increased metabolism causes to rise.
These frankly organic cases rarely had high frequency attacks. DR. TOM A. WILLIAMS, Washington, D. C.: Will Dr. Clark explain the eccentric convulsions such as when there is uraemia, on similar grounds? Also, if he will postulate in such cases as recover with metabolic treatment.
It has been shown that the pancreas, the spleen, the thyroid gland, the suprarenal capsules are absolutely essential, each in its own way, to the health of the organism, through metabolic changes which they alone seem capable of performing; and it is suspected that various other tissues, including even the muscles themselves, have somewhat similar metabolic capacities in addition to their recognized functions.
Further, that the functions of digestion and assimilation and the various metabolic changes are so largely under the control of the nerve-centers that nothing seems more likely than that so great a disturbance of that system as takes place at the menopause should cause secondary derangements of these most important functions.
Conversely, the application of sulphur can help where weakness of the metabolic forces produces rheumatic or gouty sediments in parts of the body whose function is to serve by their mobility the activities of the will. In this case the abnormal predominance of the quality 'dry' can be counteracted by the medical application of sulphur.
The isolation of thyroxin has made possible the determination of the influence of the thyroid hormone upon the evolution of energy in any higher animal organism. There is, for every individual, a constant, known as the metabolic rate, or the combustion rate, a reading of the rate at which his cells are consuming material for heat.
Clearly enough, then, we must look upon the nucleus as the special agent in reproduction of cells. Again, we have apparently conclusive evidence that the nucleus controls that part of the assimilative process which we have spoken of as the constructive processes. The metabolic processes of life are both constructive and destructive.
When the married lovers are ready to have their children, it is naturally with the woman that the doctor is most concerned, correcting structural or functional deviations or mild organic disease before the pregnancy has advanced too far, seeing to it that the glandular mechanisms do their important work, that nutritional intake is sufficient, that digestion is kept successfully functioning, that metabolic processes are raised to more than ordinary efficiency, and that the body is kept free from all toxins and infections.
Their tail is very strong and helps them in swimming. They have a very low metabolic rate and thus need to hunt only every few days. They can decrease their metabolic rate and stay under water for a long time. Alligators have been known to stay under water for upto 6 hours. They do not make any unnecessary movements but can move very fast even on land when necessary.
Now if adrenalin caused these changes merely as a metabolic phenomenon and not as a "work" phenomenon, then the injection of adrenalin into the carotid artery of a crossed circulation dog would cause no change in its circulation and its respiration, since the brain thus injected is in exclusive vascular connection with the body of another dog.
