...antis make much of the fact that AB-57 -- a dilute solution of ammonium bicarbonate, sodium bicarbonate, a fungicide and gelling agent in water -- has been used for cleaning stone. But on stone it is left for between one and 24 hours and is strengthened by the disodium salt of EDTA, a substance that aids in the removal of calcium compounds; on the Sistine frescoes it is used in a weak solution, in varying applications lasting at most three minutes. It is an efficient solvent but a bland reagent. The fear that the cleaning has taken off any of Michelangelo...
...lead poisoning exist? Yes, provided it begins before too much damage is done. Doctors get the lead out with a process called chelation, using drugs that bind to the metal in the bloodstream, allowing it to be flushed out in the urine. The drug of choice has been calcium-disodium EDTA, but it is usually administered intravenously over several days in a hospital. The Food and Drug Administration has approved for + use in children an oral drug called DMSA, which does not require hospitalization. But effective as chelation is, doctors point out that medical treatment cannot substitute for a safe...
Leach It Out. Early detection is difficult because parents rarely take a child to a doctor for the first, seemingly minor complaints. But prompt diagnosis is essential if modern treatments are to be effective. Professor Samuel P. Bessman of the University of Maryland found that disodium calcium ver-senate will selectively leach out the lead from a child's system without robbing him of precious calcium. Now doctors are trying combinations of versenate with urea for double action...
...stubbornest disorders to treat is painter's colic-lead poisoning. Two Alabama researchers report in the Annals of Internal Medicine that they have treated 19 cases easily and successfully with a trick salt called disodium calcium versenate. Lead replaces the calcium and is expelled in the urine...
Last fortnight the most promising anti-t.b. drug to date was announced: Professor George W. Raiziss of Abbott Laboratories reported in Science that disodium formaldehyde sulfoxylate diamino-diphenylsulfone (short name: Diasone) is the best drug yet used to treat guinea pigs newly infected with tuberculosis. It is a sulfa drug which Professor Raiziss says is even better than Promin, another diaminodiphenylsulfone derivative, hitherto the best anti-t.b. drug. Three good points about Diasone: it is only slightly toxic, therefore can be used in fairly large quantities with safety; it is as good as sulfanilamide in curing streptococcus infections...
