...when a bomb made a direct hit on a one-story brick house, setting it on fire. Up drove a "catastrophe" ambulance from Bellevue with interns and nurses; up drove a red Consolidated Edison truck to fix broken gas mains and cables; a station wagon with "Mobile Blood Plasma Unit No. i" on the side...
...series of ingenious experiments, researchers found renin, an organic chemical manufactured by the kidneys, which raised the blood pressure of animals. They also found an activator in the blood plasma which enabled renin to work. The combination of renin and this activator was dubbed angiotonin. As a working hypothesis, angiotonin was marked as the chemical cause of high pressure. Further experiments showed that normal kidneys probably manufacture an "inhibitor" substance, which destroys or neutralizes surplus angiotonin, keeps the pressure within normal bounds. Two research teams, including Dr. Page's in Indianapolis, recovered from kidney extract inhibitors which lowered...
...steel balls used for rotors. Before they exploded, the investigators got up to more than 6,000,000 r.p.m., to rim speeds of 3,500 miles an hour. So far they have done little with this machine on separation of uranium isotopes. They are more interested in separating blood plasma from blood for storage and shipment to war-pounded Britain...
...prepare a glue, the scientists withdrew blood from an artery of a young cock, spun it in a centrifuge. The heavy red blood cells were thrown away and the clear plasma packed on ice where it stayed fresh for six weeks. Into the plasma the experimenters poured a few drops of chicken embryo extract, "a powerful clotting agent...
Then they cut the large nerves in the legs of several rabbits and dogs, held the stumps close with forceps, dribbled the plasma over them from a pipette. Within two minutes, the plasma thickened to a firm jelly which stuck to the nerves and united the stumps. The jelly held for several days, long enough for the growing nerves to twine themselves on to the cut ends, like vines on a trellis. Healing took about ten days. Next step: use of the blood glue on torn human nerves...
