...palm-size pacemakers, developed by the ARCO Nuclear Co. of Leechburg, Pa., with a grant from the Atomic Energy Commission, use no batteries. They contain 400 mg. of the radioactive isotope plutonium 238. As it decays, the plutonium generates heat. That raises the temperature of a thermocouple system, which converts the heat to electrical power for the pacemaker. The device is similar to the nuclear pacemaker inserted in a French patient in 1970 and now used by 24 Americans. Both pacemakers are expected to operate for at least ten years. That is long enough to make the previous chest operation...
...shot was a heart-stopping 200 mg. of morphine injected directly into a vein. Both Mrs. Postma and her husband are doctors in The Netherlands, and she knew exactly how to give the injection. The matter could have ended there; at 79, the old lady might well have died without arousing any suspicion. But Dr. Postma, who has a reputation as a woman of principle, went to the director of the old-age home, explained what had happened and asked him to sign the death certificate. Instead, he called the police. When they failed to act against the popular doctor...
...drug's effects on the body can, in fact, be deadly. Most doctors prescribe methaqualone in capsules of 150 mg. to 300 mg., one of which should be enough to put the average adult to sleep. But drug abusers are not content with such tame dosages. Their usual pattern is to take two or more, and then wash them down with a few pints of beer...
...much money as builders had expected. Says Kenneth D. Campbell, president of Audit Investment Research, which specializes in real estate: "It wasn't really an industry at all. Just a bunch of companies with big hopes.' Some companies like Behring and Potlatch took great pains in design mg and equipping their plants, only to find that they could not generate enough volume to cover their investment and high fixed operating costs...
...Doctors can find no conclusive evidence that vitamin C in large doses prevents heart disease or effectively treats cancer. Vitamin C's function as a cold cure is also uncertain. Its safety-if taken in quantities hundreds of times greater than the recommended daily requirement of about 60 mg.-is questionable. Though deficiencies of vitamin E will produce the symptoms of muscular dystrophy in rats, doctors are not yet convinced that such symptoms may exist in humans. "Vitamin E," say some physicians, "is a cure looking for a disease...
