...chemical, nicknamed PAM, which proved an effective antidote to deadly nerve gases. Now his explanation of how nerves work offers insight into yet another obscure matter: how nerves are deadened by anesthesia. The discovery that such anesthetics as procaine and the Indian poison curare combine easily with the receptor protein, blocking the biochemical reaction, could lead to better anesthetics and more efficient drugs for treating disorders of the human nervous system. "One of the basic functions of human life is coming closer to being understood," said Dr. Nachmansohn...
...isolating a "receptor" protein, the Columbia biochemists proved that the same reaction that takes place at the synapse is repeated all along the length of the nerve. When a nerve is stimulated, a chemical called acetylcholine is released within the nerve. It combines with the receptor protein, causing an interchange of sodium and potassium ions. The ions in turn trigger release of more acetylcholine a bit farther along the line, letting the current advance. To turn off the signal, an enzyme, cholinesterase, is released that instantly destroys the acetylcholine in the nerve...
...Williamsburg section, an American Cyanamid Co. tank truck backed up to the Radio Receptor Co.'s plant (which makes electronic equipment) to deliver 500 gallons of nitric acid. Driver Benjamin Sidla hooked up his hose to a pipe indicated by employees, started pumping. After a few minutes, a man rushed up from the basement, yelled to Sidla: "You'd better stop. The fumes are terrible down there." Somehow the nitric acid had been diverted into a 3,000-gallon tank containing hydrochloric. Result: royal water, which was already beginning to dissolve the tank's rubber lining, eating...
...Radio Receptor employees staggered to the street, coughing and choking, their eyes burning. Some collapsed, some vomited. Emergency squads gave oxygen, took dozens of workers to four hospitals; 18 were kept overnight, and some longer. Assistant Deputy Fire Chief Walter C. Wood cleared a two-block area around the plant, kept residents out until 3 a.m., when he thought it was safe...
This experiment has led Dr. Bogoch to believe that the isolated brain constituent is chemically either similar or identical to the natural receptor substances in the brain. It therefore attracts the viruses to itself and prevents their damaging the brain...
