...amount of fluoridated water consumed during childhood nor the number of germs in the mouths seems to make any difference. In the saliva of these fortunate persons, reported Dr. Green, he has found an antibacterial substance. He still does not know what it is, only that it is a protein and resembles the proteins of which antibodies are composed...
...Green has high hopes of a decay-free future once he has identified this protective protein, learned how to make it, and how to give it to people who do not naturally produce it. Another possibility would be to separate the antigenic fraction of the mouth germs that cause decay and inject it to stimulate active immunity through antibodies. This would amount to vaccination against tooth decay...
...Laureates last week were British Scientists Dr. John Cowdery Kendrew, 45, and Dr. Max Ferdinand Perutz, 48, of Cambridge's Laboratory of Molecular Biology, who shared the Nobel award for chemistry. After involved experiments using X rays, Perutz and Kendrew mapped the complex three-dimension architecture of two protein molecules-hemoglobin, which carries oxygen in the blood, and myoglobin, which delivers oxygen to muscles. This achievement is an important early step toward a more complete understanding of proteins, the building blocks of all life...
Plasma (the blood's clear fluid) is supposed to carry most of the blood's circulating protein supply, but there is always some protein outside the bloodstream because it has leaked through the capillaries -surprisingly as much as half of the blood's total stock. By a still-obscure method, the lymphatic system picks up this protein,, which then flows to lymphatic collection points. Biggest of these, in the abdomen, is the cisterna chyli. Others are in the chest. Through large lymph channels-notably the thoracic duct-the protein returns to the blood stream. Most surprising...
...sharp drop in the plasma's protein content (the result of drastic surgery, a burn or an accident) is one of the factors that make shock catastrophic and possibly fatal. So the long-mysterious lymph system is a means of combating shock...
