Oyanguren and E. Bartholin Rev. mcd de Chile 71 464 May 1943 The diagnosis of silicosis has been confirmed by demonstration of silica in the sputum and blood of 40 individuals Silica which is conveyed to the lungs by inhalation is taken up in greater part by the lymphatics and the remainder is expectorated Silica interferes with the lymphatic circulation producing a fibrous proliferation which eventually results in the inclusion of the particles themselves But before this occurs the silica which is inhaled passes through the blood and may be excreted in the urine Silica mey normally be found in the blood but if the quantity is less than 8 mg percent as determined by the colorimetric method it is believed to be of no clinical significance Quantities from 12 to mg percent are expressed as 1 plus from 20 to 50 mg percent 2 plus and above 50 mg percent 3 plus Positive chemical reactions for silica in the sputum may be obtained in all cases of silicosis The positive reactions in the blood correspond to the amounts of silica contained in the sputum and positive chemical reactions are found only in those individuals who have been exposed to bearing dust The specific chemical reaction used is that described by Oberhauser and depends on the reaction obtained with nitromolybdonate of ammonia This may be used equally on the blood and sputum and is a more certain test than the spectrographic mathods -~- Am Rev.
