Pharmacol., TO. 201-10 (last Polyvinyl alcohol is a long-chained polymer which forms a viscous colloidal solution In water* The Immediate affects of intravenous injection in dogs and rabbits are a decrease in erythrocytes end hemoglobin end an increase in sedi mentation rate due to aocelsratod conglutination. Repeated injections Impair oj suppress clotting. The general effects are much like those produced by acacia solution. Polyvinyl alcohol is retained in the blood, 3pleen, liver, kidneys, lymph nodes, otc., for many we v.3. 513 Chronic Poisoning by Benzine Vapors. G. Penni and C. DeStefonis. Rasa. mod. ind. n, 516-38 (1940). (Italian). In experiments on guinea plge and albino rats at a concentration of benzine (no* purified, containing benzone) of 0.015 g. por 1. air, a true poisoning was not observed; at the concentration of 0.025 g. por 1. the toxic action begins, but disappears if the inhalation ceases; with greater concentrations there Is a serious toxic action. The histological rosuits are shown and discussed. 514 Industrial Solvents as Possible Stlologic Agents in Myeloid Metaplasia. R. Rawson and others. Science v3. 541-2 (June 6. 194l). A comparison of the histologic fiodinga in agnogenle (cause unknown) myeloid metaplasia with those found in chronic boazol poisoning together with cox-tala clinical evidence led to an investigation>lnto the occupational histories of* tto patients in this clinic with myeloid metaplasia. All of the six available fbr study gavo a history' of oxposure to certain industrial solvents Including bnzc and carbon tetrachloride. The feets suggost that exposure in some individuals to certain fat solvents may result in the alinlcal picture previously described as agnogenle myeloid metaplasia. 515 A Portable Pnlt for the Determination of Halogonatod Hydrocarbons. H.C. Dudley Pub. Health Repta.. 56. 1021-1087 (May 9. 1941). This is a description'in detail of a portable unit for the thermal dacompoaitior and determination of halogenated hydrocarbons in air. The principle of this sampling device Is similar to that employed by others, the air stress being pais ed through samo typo of hosted tubo, which serves to decompose the organic halides. Chemical tosts are finally employed -- tho gravimotrlo determination of the silver halides having boon found to bo more advantageous with smaller amounts of halogens. Analysis of standard samploa indicates that, at a complin rate of 2.5 liters per minute, recovery of carbon tetrachloride and trlcbloreth lone is quantitative. 516 The Prophylactic Pee of Sulfonated Oil in Cement Dermatitis. I. Plncus. H.Y.- Steto 7. Med., 40, 1391-3 (1940)J ! Two oases of oement dermatitis aro presented, whloh resisted all attempts at pe manent cure until sulfonated castor oil was used Instead of soap. The irritant action of soap is based on the type of fatty adds and the nklwllne roaction- The mixed fatty adds in sulfonated castor oil abow a minima Irritation and tt pH is slightly on the add side. 51? occupational Dermatitis in Cigar Makers Due to Contact with Tobacco Leaves, t. Vanand S.Oenovose. ArduDonu fcSvphll.. 43. 257-263 (February. 1941). A report of tfaroo oases of occupational dermatitis In dgar makers working in 1 same factory* It was due to contact with tobacco leaves and was attributed to acquired sensitivity to recently fermented tobacco loaves. Tho condition In al tbroo cases proved recalcitrant to therapeutic measures and cleared up onl] when working with tebacco was discontinued. In determining the oause of derma* title in this industry, acquired sensitivity must be kept in mind.
