Digest of Industrial Ryglene - 15, 4GB Basedow18 Disease from Carton Monoxide Poisoning. I. Ifahaln. Her. Bed. sulesi rom. 60. S88 tl940); Zontr. Gewarbehyg. Pnfallverhut. 27, 193 (1940). (Ooxaan). ' A 37 year-old woman Buffered In wlntor from progressive weakness, which com pletely disappeared In suamor. Basedow's disoqse developed during lest winter. The cause was a defective stovo which gave off auch carbon nonoxide. The case dlfferod from those previously dosorlbed in the literature In that the symptom developed very slowly (3 winters) during on insidious poisoning. Kzopbthnlaos was absent. The similarity between carbon monoxide poisoning and Basedow* s dli v=0 ease is discussed and the relation of Basedow* a disease to changes' In the mesencephalon is pointed out. ` 469 Danger of Chlorine Oae. Froltag. Z.gea.Scliless-u. Sprengstoffsw. 35. 159 (1940). (Ooroan). Several instances of poisoning by chlorine gss are described. Methods of trea: meat are suggested. Venesection and oxygen Inhalation are recommended. ToXic !! action on m&n is described as follows: 0.01 ag. per 1. can be breathed for several hours without serious offects; 0.1 to 0.15 mg. per 1. is lethal In 1 t< 1. 5 hours. 470 Chromate Method for the Determination of Sulfur Dloxlda In Air. P.V. Moakalev. Lab. Prakt. (U.3.S.R.) 15, 26-8 (1940). (Hussion). Chen. Abat., 35, 1353 (Marci 10,1941). The author has modified the method of Lang by making seme alight ohamgss la reagents, end presents details of the analysis. Sufficient details for practi cal use arc given in the Chemloal Abstracts reference. Filter papers washed in e solution containing 4$ of sodlm nitroprusslde and 2! ' of sodium carbonate will detect sulfur dioxide et a concentration of 1 port pec million and hydrogen sulfldo at 1 part In 5 million. 472 X-Rcy Diffraction -- An Important Tool la Pneumoconiosis Bsaearoh. L. H. Borkalhaner. Jour. Ind. A Toxlool.. 23. 163-175 (May. 19411. Sevon representative and varied Instances are described in which x>-ray dlffrao tion has boon of assistance in pnoiaaoeonlosia rosecrch. Mineral specimens and dusts, the ohoaically extracted mineral residues of lung tissue, slx-mlcron se tlons as well as thicker sections, and dried and pulvarized lung tissue hors a been subjected to x-ray diffractions with satisfactory results. Tbs poaslblli of identifying minerals present In the same section that tho pathologist has studied has been demonstrated. This may not bo feasible In all easea dace th dust concentration is a limiting factor but It can bo used in many Instances a It bos on advantage over methods involving dust retrieval which may alter the composition of the minerals In the process. The erroneous Implication that th mineral pyrophylllte was the cause of a reported oase of nodular fibrosis has boon considered; and proof by x-ray diffraction analysis Is offered that tbs case In question was ana of disease due to quarts rathor than pyrophylllta. X-Bay diffraction has its limitations but within thorn It has proven an Invalu able old In pnoumoconioels research. 473 The Medicolegal Aspects of Roentgenology. J.W. Pierson. Medical Cllnios of 8 America 25, 331-46 (March, 1941). The medicolegal aspocts of roentgenology may be considered from three angles: (1) the presentation In court of testimony based on roentgenologic findings; ( the preparation of the proper foundation for such testimony by accurate roantf
