...concept of autoimmune disease. It has long been accepted dogma that in ordinary healthy immune reactions the body is using a birthright of every living creature. This is a set of biochemical sentries which raise an alarm when the body is invaded by a foreign substance, especially a protein, so that the system can make antibody to neutralize the invader. "Normally," says Dr. Dameshek, "the body has safeguards so it can recognize 'self as opposed to 'not-self,' and it will not damage 'self materials. Occasionally these safeguards break down." Dr. Dameshek detected such a breakdown...
From Eye to Eye. The most clear-cut and comprehensible autoimmune diseases form a small, exceptional group. Thousands of the body's countless proteins circulate in the blood or are washed by it, but a few are "sequestered": the fluid in the eye's lens, sperm secreted in the testicles, and thyroglobulin (an iodine-containing protein), which usually stays locked in the thyroid gland. If lens fluid leaks into the bloodstream after injury, its proteins start the antibody factory working and the body seeks to destroy the lens proteins...
Fascinating Mono. In these three cases, it is easy enough to understand how the body can regard the escaping antigen-protein as "new" or "foreign," because it has been sequestered for years, perhaps since the fetal stage. Far more knotty are the questions that arise so often in Dr. Dameshek's practice as a hematologist. No less than 50% of all blood-destroying anemias acquired after infancy, he believes, are the results of autoimmune reactions. He is so confident of this that he abbreviates the disorders to AIHA-autoimmune hemolytic anemias...
...greatest problems was "too much fat in our beef," a new viand went on sale in New York. The product: Chet Huntley's Nature Fed Beef, advertised by pictures of a lean and hungry Chet and by promises of "quality and flavor, plus low fat and high protein." The fat was in the fire, and NBC, prodded by a local packer, ordered Huntley to trim his name and face from the chopped chuck and sirloin. Good night, Chet...
...meat is sold as a delicacy in Japan, can be found as pet food in Sydney shops at 23? a can. Some consider this a waste. "In kangaroos," says Basil J. Marlow, curator of mammals at the Australian museum in Sydney, "you have a valuable source of protein. Instead of being shoved into bloody dogs and cats, it could be more profitably shoved into humans. Kangaroo meat is quite tasty when properly butchered...
