v--j >=: (0 References to Recent Literature - 11 crg.tns and tissues examined. The lead distribution in animals treated with both lead and roentgon ray was essentially the 3anie as that following the administra tion of lead only, although changes in lead concentration wero found in certain organs. 48 EFFECT CF G-KYD!tIL IN LEAD POISONING. F. Schmitt and K. Lossie. Arch. f. klir.. !:ed. 192. 200-3 (1958). (German). A r3port is given of ono case of load poisoning which was treated with S-Hydril (stabilized sodium thiosulphate) given intravenously. After giving 2 ampoules daily (it is not stated for how long) the clinical symptoms recoded. After 8 day3 there was n significant decrease in blood load and after 14 days the valuos were normal, 49 MICROCHrAilCAL DETECTION aND DETERMINATION OF LEaD. N.D, Costeanu. Mikrochim. acta 5, 236-8 (1936). (Austrian). A drop of hydrogen iodide solution, prepared by introducing hydrogen sulfide into n mixture cf iodine and weter, is placed on filter paper which has been drenched with the solution to bo tested and dried in on oven. The resulting yellow spot of lead louido is compared with spots similarly obtained with known concentration! cf lead solution. The method applied to the analysis of 0.4 g. of brass showed tho probable presence of 0.025 por cent cf load. 50 QUANTITATIVE DETERMINATION OF LE^D IN BIOLOGICAL MATERIAL: MODIFIED DITHIZOBK METHOD. F. Schmitt and li. Basse, Arch. f. exp*. Path. u. Pharmakol. 169. 189-71 (1958). (Gorir.n). A description is given of ?. modification of Soelkopf and Taegor's dlthizone method. The hynr^gon sulfide precipitation is eliminated from the prooess. In stead, tho ash residue is dissolved in hydrochloric acid and tho iron Is removed from the hydrochloric acid solution by shaking with ether. 51 KlCROCiiBJIC.J, METHODS FOR DETERMINATING LEAD ELECTROLYTICALLY AND BY MEANS OF DITHI20HE. i;. Muller. Z. Anal. Chen. 11, 181-82 (1938). (German). Numerous experiments ure described in a re-/lev/ of 22 papers published since 1928, in which tr.u electrolytic and dithizeno methods were subjected to vigorous test ing. Both require cleanliness in apparatus and purity of reagents. Tho weokr.es: of the dlthizone method lies in tho reactivity of the dlthizone with other catio: and the fact that tho reagent is expensive end doos not koop woll. Although the electrolytic method also has its drawbacks it seems boet for lead determination in organic materials. Full details for both determination uro described. 52 EXPERIMENTS ON THE EFFECT OH THE THYROID OF CARBON MONOXIDE INHALATION. H. Reploh. Arch. f. Hyg, 120, 244-57 (1938), (German). In experiments on guinea pigs and rabbits, the author induced acute, 'sub-acute" (repeated) and chronic poisonings, tho latter by small amounts daily for several hours, for ns long as 12 months. Tho offeet on the thyroid waB most marked in the chronically poisoned .animals. Tho experiments support the view that there 1: a chronic carbon monoxide poisoning, and tend to dispute the theory that the poi* soning is .cnly a r;nttor of anoxemia. 53 A CASE OF OCULhR r-IoTURE.dlCE CAUSED BY GnS FROM A MOTOR. B. Koslowski. Klin. Oczna i, 176 (1938). (Polish). The driver of a biased meter car was asphyxiated by products of combustion which had no exit tc the outside. hun ho regained consciousness 9 hours later, he could not see and u,n examination after 6 days he was found to have a left homonymous hemianopsia which touched the fixation points. He recovered spontan eously within 2 w=oks. Tho carbon monoxide may have producod an angiospasm, or homorrhago which compressed tho visual pathways. HWBB-0089785
