Science Shows NOISE Causes Indigestion
WORKING with various intricate devices that record the effects of sound waves on the digestive processes, scientists have found that a lot of digestive troubles are directly attributable to noises. Dr. Donald A. Laird, of Colgate University, has discovered the effects of various noises on the digestive juices
Using two different methods on a chosen group of healthy men, the experimenter measured the effect of discordant sounds upon the flow of saliva. It was immediately evident that many sounds had a distinct effect. For example, when the sounds increased in volume comparable to the noises in a quick lunch restaurant, the secretion of saliva decreased to almost half of the normal quantity.
Odd Service Brings Movies to Patients
A WOMAN invalid’s desire to see movies of the New York World’s Fair suggested a popular and profitable service to a New York motion-picture operator. Now he brings his projector to bedridden patients, entertaining them with film dramas or with travel pictures of places they would like to be able to visit. For children, his repertory includes animated cartoons.
Hospital Boasts Safety Chute
The Piedmont Hospital in Atlanta, Ga. is equipped with a spiral chute by means of which bed-ridden patients can reach the ground quickly in the event of fire. On each floor of the hospital there is an entrance to the chute and in an emergency the patients are slid down it on a mattress.
On duty 24 hours a day, a small ambulance can speed down the aisles of a big factory to pick up any worker who becomes sick or is injured. The ambulance, made from a Crosley station wagon, provides quick pickup service inside the Transformer Division plant of the Westinghouse Electric Corporation at Sharon, Pa. The factory is 3/4 mile long.
“Cross-eyed” X-ray Casts 3-dimension Image
X-RAY shadowgraphs have heretofore displayed only two dimensions, height and width, but with the recent development of the “cross-eyed” X-ray a third dimension, depth, is added, making the image appear like a sculptured skeleton.
The three-dimensional X-ray is the invention of Prof. Jesse W. Du Mond, a Pasadena, California, scientist, who calls his instrument a “Stereofluoroscope.”
The main element of the machine is a pair of X-ray tubes whose beams, directed against the patient as illustrated in the drawing above, intersect in the body, thus casting shadows in two different planes.
Cough Drop Has Liquid Center
COUGH drops that have liquid cough medicine in their centers are now on the market. In manufacturing the remedy, a teaspoonful of a cough sirup is placed within a hollow candy shell, and the open edge of the latter is sealed. The shell dissolves in the mouth of the user, releasing the cough sirup.
Hand Pump Restores Breathing
Life-giving air is forced into the lungs of a patient by a hand-powered pump developed by a Swiss doctor, who expects it to be useful in treating soldiers after poison-gas attacks. The plunger pump forces air or oxygen through a tube leading to a mask held over the mouth of the patient.
Insane Patients Helped by Electric Shock Treatment
Fighting insanity with electric shock is the most dramatic recent advance in the field of medicine. At the New York State Psychiatric Institute, in. New York City, seemingly hopeless cases of the most common forms of insanity, schizophrenia and dementia praecox, have been shocked back to apparent mental health by the new treatment. Electrodes, at the ends of a caliperlike instrument, are placed just in front of the ears on the patient’s head. From seventy to 100 volts of current pass through his brain. The result is a violent convulsion resembling an epileptic seizure.
In some cases, a single electric shock achieves what seems to be a medical miracle, restoring the patient to sanity. Previously, insulin, snake venom, and metrazol, have been used to produce shock. The electric treatment is painless, leaves no after effects, and costs less than shock-producing drugs.
Device Takes Measure of the Teeth
WITH the aid of the “gnathograph,” an instrument as mouth-filling as its name, a dentist’s patients may now be assured of a perfect fit for artificial teeth. Fitted to the jaws as shown above, the new device registers the arrangement of the teeth and the direction of the “bite,” to guide the dentist in straightening teeth or fitting inlays, crowns, bridges, and plates. Its inventor, Dr. Beverly B. McCollum of Los Angeles, Calif., demonstrates in the picture at the right how the instrument is then mounted for use in tooling a plate to just the right shape to give the
most comfortable fit in the mouth.
London Hospital Constructs $200,000 Radium Mercy Bomb
CONTINUING the work begun by the late Madame Curie, eminent French pioneer in the use of radium for healing, physicists at the Westminster Hospital in London are now engaged in the construction of a $200,000 radium bomb which will greatly extend the mercy work of the beneficial rays. The 4 grammes of radium, worth $200,000, will be encased in a new tungsten alloy shell, the alloy having 1-1/2 times the density of lead. Within the shell will be a solid gold collar to further confine the Gamma rays of radium, thus preventing injury to the operators from spreading rays.
The employment of so great a quantity of radium within a single bomb permits operation at a greater distance from the patient, and at the same time produces a more effective treatment at greater depths below the body surface.
