...have to eat his Ersatz foods. From sawdust Bergius has extracted a digestible sugar, equal in food value to barley. Of the sawdust 60% to 65% becomes sugar, 5% acetic acid, 30% lignin which can again be used to make charcoal or wallboard. The sugar can be converted into protein by treatment with yeast; into fat by feeding it to pigs. Apparently, up to the outbreak of World War II, food-from-sawdust in Germany was fed only to animals...
Last week in Modern Medicine, Dr. Bayard Taylor Horton and associates* of the Mayo Clinic at Rochester, Minn* announced a new method of treating the "constant, excruciating, burning, boring" headaches of chronic alcoholics. When the system is flooded with alcohol, large amounts of histamine, a protein derivative, pour into the blood stream. Somehow, said the doctors, the histamine expands blood vessels in the head, causes hangover headaches. Strangely enough, they found that "immunizing" injections of minute quantities of histamine brought permanent relief to 65 patients, no improvement to ten patients...
Last week the Ford chemurgic laboratory at Dearborn displayed pride in a promising new fabric from soybean meal -said to be the first textile made from a vegetable protein.* Mr. Ford was presented with a tasteful necktie one-third of which was woven from the soybean fabric, the rest of silk and wool. Protein is extracted from soybean meal in saline solution, then mixed with other chemicals to make a viscous liquid, which is squirted into hair-sized filaments. The spun thread has a pleasant feel, fairly good tensile strength, takes dyes readily. Its intended use: automobile upholstery...
...virgin rats to mother chicks and ratlets with great affection. This earned prolactin the nickname of "mother love" hormone. The implication of the discovery was that mother love, though doubtless fortified and colored in women by training and tradition has a physiological basis in a chemical substance-probably large protein molecules. (Dr. Riddle found that prolactin and other front-lobe hormones are disintegrated by trypsin, an enzyme which has the special property of "digesting" proteins...
Chemical Clue. At the American Association for the Advancement of Science meeting in Richmond, Va., 28-year-old Dr. Charles Frederick Code told of his researches on histamine. For them he was awarded the Theobald Smith award of $1,000. Histamine is an organic chemical, a product of protein decomposition. Scientists have long known that histamine is especially concentrated in the cells of the lungs, liver and skin, but they did not know where it came from...
