1973Volume 92,Number 4  \n# LASERS AID IN RESEARCH ON DISEASES\n\nUniversity of Georgia scientists are using high intensity lasersto conduct fundamental research that is opening new doors topractical understanding of disease and other health relatedproblems.  \nDr.John W.Lee,associate professor of biochemistry,saidlasers are being used for the first time as a practical too1to generate singlet,or delta,oxygen.  \n\"Singlet oxygen is a hyperactive cousin of the ordinary oxygenmolecules which circulate in the air,\"said Lee.\"Somescientific evidence indicates that important biologicalprocesses create singlet oxygen out of common oxygen,andthis is a process vital to the way the body uses oxygen andfights disease.\"  \nYet,he added,very little previous research on this remarkablesubstance has been possible because of the difficulty ofisolating the singlet oxygen reaction in a clinical setting·Lee and Dr.Ian Matheson,another university biochemist,turned to the laser,which Lee said has untapped potentialin disease research,for a solution to this dilema.  \n\"Light induces many chemical and physical reactions,\"saidLee.\"Anyone who takes a picture with a camera knows that.We introduce regular oxygen into a metal cylinder underhigh compression,and shot an infrared laser beam throughit to see what would happen.The reaction was a1mostinstantaneous.We produced large quantities of singletoxygen without biproducts or chemical catalysts.\"  \n\"One out of 100 babies contract this disease,\"said Curry.  \n\"It occasionally can lead to cerabral palsy or mental retardation.The most effective treatment is exposing the baby to fluorescentlight for a number of days.Nobody is certain why this works,but some doctors and scientists speculate that the light  \nCopyright  1973,by Industrial Research,222 S.Riverside Plaza,Chicago,I11.60606.Reproduction prohibited without permission.  \ninduces singlet oxygen molecules in the blood stream.\"Withthe help of Lee's laser equipment,Curry conducted researchthat determined that creation of singlet oxygen destroysthe bilirubin through oxidation.However,the mildfluorescent phototherapy that infected newborns undergoprobably doesn't induce enough singlet oxygen to effectsignificantly the bilirubin,Curry concluded.  \n\"This is a case,\"he said,\"where the treatment was rightbut the theory was wrong.\"In related research,Dr.MancyMatheson and graduate student Ron Etheridge are studyingthe effect of a blood enzyme,superoxide dismutase,onsinglet oxygen.  \nIntroducing the enzyme to the laser-induced oxygen reactionsignificantly retards the conversion process.\"Ordinarily,it takes only 10 sec for the singlet oxygen to destroybilirubin,but the decomposition stops dead when the enzymeis added,\"said Lee.  \nThe researchers believe that superoxide dismutase plays animportant role in the cellular metabolism of al1 living thingsby controlling the hyperactive singlet molecules so theydo their work without detroying the activities of the livingcel1 in the process.  \n\"Singlet oxygen has been found important in many other lifereaction,\"said Lee,\"Some scientists say that it is theweapon the white cells use to kil1 bacteria in the bloodstream,and may also play an important role in the breakdown andabsorption of certain vitamins and fatty acids.The lungtissue must convert regular oxygen to a more active moleculesimply to breath air.  \nLee said laser have given scientists a practica1,uncomplicatedway to duplicate a vital biological process.\"We should nowbe able to unrave1,under laboratory conditions,a lot ofvery complex physiological mysteries,\"he concluded.900 MHZ TUBE AND CAVITY PRODUCE OVER 150 WA new \"Cermolox\"tube and cavity combination that producesover 150 W of
