hich Prof Blackledge Has Succeeded In Extracting Almost Pure Toxicodendrol for Conversion Into Poison Gas thiee small “shots” of the extiact a week apart some of us may go out in the woodland glens and revel in poison therefrom Others ivy with no may not There are all degrees of susceptibility to Rhus toxin from almost complete immunity at one end of the scale down to auch intense susceptibility that even a minoscopir amount of the toxin may cause death though fatal cases usuallv Dr Donald says are complicated by the presence of stieptococci Nine laige Amencan laboialoiy establishments have been licensed by the Pederal government to pioduce poison ivy extract for purposes of inducing immunity and six have been licensed to prepaie poison oak extract The method of pioduction is practically identical and can swiftly be standardised so that other laboiatones could get into rapid production if emergency quantities weie ir Germany Testa Are Said to Have Demonstrated That It la Not Proof Against the New Poison Ivy Gas HREE old soldiers of misfoitune ivy poison oak and —poison poison sumac — havqemerged from their loiest ambushes to join the rank of Amenca’s defendeis Research chemists in Berkeley Calif have perfected a quantity process for extracting from these members of the botanical “Rhus” family their toxic principle called -- it has been found is must wear an rubber suit in addition to a new1 fangled mask Even then his chances of escaping a serious attack of ivy poison will be very remote He will be incapacitated for days Laboiatory workers who have been accidentally in contact with drops of tomodrendrol say that the effect on human skin is as severe as that of mustard or phosgene gas and that like mustard gas toxicodrendrol may be incorpoiated in military proiectiles such as shells Again in similarity with mustard ga toxicodendrol tends to remain lesidual on such objects as stones woodvmk military gear and clothing fiorn which tne unwary soldier or civilian mav obtain an unusually severe “case” of poian-tig- son ivy As most of us know poison ivy is no jo’ e in fact it can be fatal and is often completely incapacitating according to Dr W ( Dmald director of the Lm-'ersi- ty of California Rut the campus Cutter Iaboratoius infirm-t- r of Bcr-k- e which are now ptoduemg have also found a way to set this toxin on guaid in the human system actually to prevent its own ravages on the human slun Paradoxically enough this extract fi un the leaves of poison ivy poison osk or poison sumac is one of modern science s contnbutions to p'aci as well one of wai s threats That is it can be used in smalt pi ophy lactic doses to confer on humankind nn immunity to ‘ p 'on of the Rhus” family In fact it u so being used as this li w ritten After ev You Can toxico-dendi- pio-tecti- Though the extract has been in pioduction for some years chemists have been endcavonng to impiove its purity with an eye to wider application of the toxin Recently a rescaich chemist L Brennan Blackledge of Berkeley Calif evolved after Id yeais’ concentration on ibis chenucal m ahlem alone an e vti act so pure that it approaches that late goal perfection The toxin pioduced by Prof Blackledge is considered the most powerful and concenjtated ever evolved in a And Prof Blackledge himlaboratory self has had to assume a constant personal risk because unfortunately he is e to one of those who aie the Rhus toxin In fact his entne work has been possible only because he constantly injected himself with pionhy-laeti- c doses of the toxin to defend himself against the "liquid dynamite” with whit i he woiked And even so he was obliged to use in addition to the rubber gloves of the laboratory constant skin washes with solutions of potassium permanganate and oxalic acid to lemove even the scantest vapor of the toxin fiom his skin Pi of Blackledge declaies he has devoted most of his life to the Rhus toxin solely to contribute to humanity s defenses against the “natuial” world and that he regiets the military possibilities of the extiact he has ptoduied Theie is leason to believe that ancient and pichislonc Amencan peoples wcie n oak mostly immune to poison ivy and poison sumac California Lmver-sity’sDonald mfoi ms us Thevlivfd in constant contact with the Rhus fam- - per-fon- plish home doclois administer the piot— tive toxin orally Here again Dr Donald draws a parallel with ancient Amei can Indian ptactice for the Indians old molds indicate chewed the leaves of supoison ivy poison oak and poison mac in order to obtain immunity to the dicca'6 on their skins This incidentally is only another pi oof of the practical wisdom and acquned knowledge of the ancient Indians in piotecting themselves against disease The effect of Rhus toxin on the human skin is contrary to public belief puiely a chemical reaction It has nothing to do with hactcna or living organisms though as stated above the ravages of the toxin may piepare the way for the and dioecious vvoik of stieptococci deaths ascribed to the Rhus familv are in reality due to production of streptococci Rhus toxin also mav cause blindness and again stieptococci aie implicated The
