Electric “Ear” Helps Photograph Heart Beats
Photographic records of pulsations of the human heart are produced by a portable instrument containing an electric “ear” and equipment for converting sound into light. The electric ear, a sensitive condenser microphone, picks up the heart’s sounds, which are amplified until they can be heard through a radio loud speaker.
OH, YOUR ACHING HEAD!
Montefiore Hospital’s Headache Clinic is seeking to eliminate our head woe
MONTEFIORE Hospital’s famous Headache Clinic in the Bronx, N. Y., is the largest in the nation and for the past ten years has been trying to find a cure for the head misery that plagues more than 12,000,000 Americans. Clinic patients are examined for eyestrain, brain impulses and blood flow to the head. Where no organic defect is found, doctors can often relieve headaches with psychotherapy. People with migraine headaches, it has been discovered, are generally of superior intelligence. Aspirin, anyone?
262 degrees, that’s pretty damn hot.
Body Can Take Heat that Boils Water
SWEATING it out in a metal box at more than 250Â° F., University of California at Los Angeles experimenters have proved that the human body can take temperatures that would cook meat and boil coffeeâ€”but only for a short time. The tests are being conducted for the U. S. Air Force to find out how pilots would react should the cooling apparatus fail in the supersonic planes of tomorrow (see Cooling “Hot” Pilots, p. 110).
Plants Grow “BLOOD” for Human Health
THE ancient sun worshippers, it now appears, had a theory of life, and its relationship to man, which has now been proven scientifically sound.
The chemists, biologists, physicians, have discovered that life comes from the sun. Furthermore, that plant life and human life are chemically related if not one and the same basic thing. Out of the laboratory of the organic chemist comes substances that show such a relationship.
Physicians have for many years been advising people to eat more green vegetables. “Old stuff!” you say? Yes, comparatively. But the green foods, such as lettuce leaves, spinach, kales and others, contain vitamins, needed by the human laboratory of the body.
Be Young at 100!
By Roger Dunham
Those creeping years worrying you? Forget itâ€”old age is mostly superstition, doctors discover.
HOW long will you live? Fifty, 70, 80â€”maybe even 100 yearsâ€”a whole century?
Till the day you die you’ll probably keep thinking you can always squeeze out at least one more year from those old bones of yours. And ever since 1848 when the average American dropped dead before 40, we have indeed squeezed out extra years until today our national life span has stretched to 67.
Fever Machine Treats Rheumatism by Short Wave Radio
THE treatment of rheumatism by short wave radio is among the benefits which radio engineers have bestowed upon modern medicine.
An instrument which makes this possible was demonstrated before scientists recently in New York. Known as the “Radiotherm,” the device works on the same principle as a short wave transmitter. The generator is contained in the cabinet, while the radiating discs act as an antenna.
The “Radiotherm” can produce artificial temperatures as high as 98 to 105 degrees. More than 500 treatments have been given.
Pocket Vapor Bulb Operates Like Flashlight
As handy as a fountain pen, an electric vaporizer that works like a flashlight has been designed as a “pocket relief” for colds. In the head of the tiny metal case is a special bulb with two openings. A few drops of a nasal inhalant are inserted from the side. When the thumb switch is pressed, the “flashlight” batteries generate heat in the filaments of the bulb and vaporize the liquid, which is then inhaled from the top of the bulb, acting on congested nasal passages.
Halitosis Clinic Studies Causes of Bad Breath
To discover the cause and cure of offensive breath in human beings, a novel halitosis clinic has just been set up at the Northwestern University Dental School in Chicago, Ill. Patients exhale through their mouths into a tube kept cold enough to solidify organic substances in the breath as they pass through. The frozen mass is then liquefied and tested by means of an osmoscope, an instrument shaped like a piccolo, which measures the concentrations of odors. Tests made so far indicate that offensive breath is most noticeable in the morning and that it tends to increase in concentration with advancing age.
Hay Fever Falls Before Zinc Ions
HAY FEVER, that mysterious malady that deprives thousands of persons of their enjoyment of summer-time, is slowly yielding before the assaults of science.
The malady, which attacks the mucous membrane of the nose and throat, causing symptoms not unlike a severe head cold, is usually caused by pollen of a number of plants, the chief offender being ragweed.
At the University College Hospital, London, hay fever is being successfully treated by zinc ionization. An electric current is employed to release the zinc ions from a solution of zinc sulphate. These are passed to the patient by means of tubes, counteracting the irritation.
Eye Ailments Cured by Dry Heat
EYE inflammations are being successfully treated with dry heat by a new and ingenious apparatus introduced at the annual meeting of the American College of Proctology.
The electric controlling unit automatically heats and circulates water through hollow rubber pads held over the eyes by the patient. The temperature of this water is constantly controlled by the physician.
