Show Baltimore Scientist Sees Hope In Cancer Cure Test With Rats By COL COLEMAN MAN B B. B JONES Associated Pre Press s Science Selene Editor Md MO AP Two AP-TWO Tw hopeful conclusions have been bee reached by Dr George Walker o of Baltimore after arter three years ears of t f re research research re- re search work with rats in his private privat laboratory Dr who was associated associate with J Johns hns Hopkins university un until I til the World war took him Into int the arm army selected rats for his in In because of ot their ex exceptional ex susceptibility to cancer He lie now has and has been able li h he says to develop two distinct strains strains' o of ot the animals ono wholly susceptible to cancer and the other othe per pcr cent immune Cancer tissue in rats tats o othe ot of tIle the immune strain he asserts either eith eith- er cr tall tail to develop and Is Js quickly eliminated or after aCter growing growIng- to a tumor the thc size of a walnut is overcome overcome overcome over over- come and gradually disappears That he regards as the most hopeful hopeful hope hope- ful tul result of ot his work thus far fat II lIe lIeis lieis Is convinced that the animals o othe orthe or of the Immune strain when develop some Omo unidentified natural natura antitoxin which h destroys the cancer cancer cancer can can- cells cOils without damaging th thE normal tissue The hypotheses on which I have haye been working contains two postulates postulates postulates lates h he explains First that In order for toran foran an animal to develop cancer cancer cancer can can- it must have a special kind o of tissue and second that in order for tor this special kind of ot tissue to change Into a cancer this tissue must have havo a prolonged contact with somo C external anti ana internal chemi chem gas cal al agent or agents The substances are probably de derIved derived derived de- de rived from tho the decomposition prodUcts products products prod prod- of ot vegetable and animal tissue Such agents are found in coal tar In shale oil and in the products oi ot of certain worms It is ls s quite reasonable reasonable reason reason- a able le to s suppose that they may be isolated so that we will know lenow just What the chemical agent or agents are If It this could be done a gr great lt light would be thrown on the whole subject and and d definite preventive measures could be taken Investigating the o of heaton heaton heat heaton on cancer cell Dr Walker has found further hope of eventual suCcess suc success suC- suC i cess In the war ivar on the tho disease having determined that although Immortal at normal temperatures they die after being subjected to Ill 2 1 degrees Fahrenheit for thirty minutes Cells thus heated in ina ina ina a a t test teat st tube and then In a susceptible rat he says have never developed Carrying this this' experiment t further he has brought the temperature of ot cancerous rats rats' under ether to 2 1 degrees and held them In that condition for tor half halt an hour Only a few rew v survived the experiment long enough to permit removal of ot their cancer tissue while they were still alive to other susceptible rats In every case he ne asserts the thc cancar cancer cancer can can- car cells were ore dead and caused no growth SEEKS REVIVAL METHOD Tha problem raised by these experiments ex experiments ex- ex Is to find a way to re restore restore restore re- re store the rats to health after putting put put- Ung ting them through the min thirty uto ute temperature test Dr Walker learned that his rats could recover after alter thirty minutes at 2 1 de degrees do- do grees but none lived longer than thansis six sis hours after being subjected to the cancer ancer destroying temperature It If a a. method can be hO worked out to keep the rats alive after aCter subjecting them to the higher temperature and the biological law thus established can be shown to apply to the human human human hu hu- man race he feels that realization of the dream of ot a cure for tor this non- non contagious but wide widely prevalent disease will ivill be only a matter of ot detail That the disease is has been accepted more or less generally generally gen gen- by physicians for tor some time but Dr Walker with rats at his disposal which clearly inherit a distinct distinct dis die susceptibility to cancer has been at pains to test tho truth of ot this conclusion for tor his Ills own satisfaction antis satis faction and tot for the reassurance of ot those who come in contact with af affected affected af- af patients Many persons who are arc In dally daily contact with will cancer patients are Me very much frightened for or fear that they themselves then might take the disease dis ease he observes es In ord r to throw some some- light ort od this subject I have taken rats of or my very er su sun sun- strain and anC put them in cages with the animals bea bearing cancer cancel They have remained for tor a number of ot months in those cages and with many animals which ha had open tumors In no instance has one become Infected I I have taken these same susceptible susceptible susceptible tible animals and fed led them over n a period of from four tour to six months Cancer ancer tissue There was not a single sin sin- gb gle one which developed the tho dis die ease I feel eel therefore safe in sayIng sayIng say say- Ing tag that the ordinary contact necessitated necessitated by the care of ot a patient Is not ot in the slightest dangerous |
