...content with elaborate heart-lung machines to permit operations inside a patient's heart, or marrow-chilling techniques to drop his temperature, Dr. Frank Gollan of Nashville VA Hospital combined the two. He has devised a cheap ($250) pump-oxygenator with a refrigerated coil like those used in bars to cool beer. Not yet ready for use on human beings, the machine has dropped a dog's temperature to 55° F., and the animal has made a good recovery after operation...
...Japanese B is transmitted to humans by the bite of a mosquito, Culex tritaeniorhynchus. Only the females are venomous bloodsuckers; the gentle males stick to flower nectar. All well and good, but mosquitoes disappear in winter. Where did they fill up with encephalitis virus in the early summer to pump it into humans? The answer was an animal, no doubt, with seasonal habits-one easily infected with the virus but not made seriously ill or killed by it. That pointed to young animals, which would promptly develop antibodies. The only creatures that fitted these specifications were birds...
...actual torque delivered to the rear wheels of the car. After 3,000 miles, carbon deposits drain off 10 h.p.; a hot summer day robs the engine of another 20 h.p. because hot air decreases fuel mixture efficiency; another 20 h.p. goes to operate the fan belt, water pump, generator, etc.; still another 20 h.p. is lost in bearing, transmission and tire friction. With gadgets, the driver of a 200 h.p. car may wind up with little more than 100 h.p. to move...
...section of the heart muscle. If the patient is moved too soon after such an attack he may die of any one of a variety of immediate causes: a state of shock, ventricular fibrillation (a disorder of the heart rhythm in which the heart ceases to act as a pump) or, less often, the choking of the heart's action from the leakage of blood through the ruptured wall into the sac around the heart...
...normal Lead I, a short, heavy horizontal line shows the resting heart. The short downstroke, which doctors call the "Q" wave, is formed as the ventricles begin to contract to pump blood out. The major part of the current flow is the high, thin upstroke of the "R" wave; the thin downstroke is simply return to the base line. Then follows the heavy, hump-shaped "T" wave that marks the repolarization of the muscle surface; some subjects also show a short dip called "S" (not pictured here) before...
