Lethbridge Herald, The (Newspaper) - May 3, 1973, Lethbridge, Alberta Thurto'oy, Moy 3, 1973 THE IETHBRIDCS HERAID THE SAVAGE CELLS: H 'Black factor' may halt cancer cells from spreading The blood serum of about 80 per cent of black people contains a substance which may help stop the growth of cancer in white patients when it is injected, according to o husband and wife team of cancer fighters in Seattle, Wash. The "black factors" appears to unblock a mechanism in cancer patients which previ- ously prevented the individ- ual's body from fighting off the invading cancer cells. This theory stems from work of tJrs. Ingegerd and Karl Hellstrom over the past several years in which they have found clues to fighting cancer in the body's immune system the some system which rejects a transplanted heart or other organ because the tissue is "foreign." Work ot the two physicion- researchers, originally from Sweden's famed Caroline In- stitute, is based on iheir find- confirmed by oth- most, if not all, can- cer tissues contain the foreign substances called tumor-specific antigens. These are not found in normal, noncancerous tis- sues in a person's body. Usually these foreign sub- stances would cause a per- son's system to produce anti- bodies, including certain types of white blood cells called lymphocytes, to fight them. But the mystery has been in the body's apparent lack of ability to knock out a cancer- ous growth in this way. The Heilstrorns have found that the blood of laboratory ani- mals and many concer patients does contain ami- bodies that are capable of killing off the cancers which their bodies harbor. And these antibodies do kill cancer cells in test tubes in the laboratory but net in the body. This is due to o substance called "blocking the Hcllstroms have discovered. It appears to pro- tect a concerous tumor from ottock by the body's lympho- cytes. Antibody It is this blocking antibody which the black factor seems to destroy. In studies, the Hell- stroms repeatedly found that serum from .certain doncrs seemed to unblock the block- ing antibody in tumor cells taken from more then 100 patients with a relatively rare type of concer called mela- noma. In other words, serum containinp the factor" enabled the bodies of mela- noma victims to more effec- tively fight off their cancers on their own. "We soon noticed that we started to recoonize some of the names of the serum don- ors. They were block peop'e who were working with us. or students and explained Dr. Karl Hellstrom in a recent interview in No- gales, Ariz., where, the Ameri- can Cancer. Society helds its annual seminar for science journalists. studv "We then did a systematic study of blocks and 'whites and found that whites react immunoiogically to ma about five per cent of the time, but blacks reacted at about the frequency of 80 per cent." As one would therefore ex- pect, rr.e'a -omos ore exceed- ingly rore in the black popu- lation.

They ore currently conducting a project with six melanoma patients who have foiled to respond to conventional methods of therapy. This study will be broadened to 60 patients in the next two years. patients will receive trans- fusions of blood from healthy black donors in an attempt to determine scientifically whe- ther they can recover better than patients receiving plas-' ma from white donors.

The present ratio in Alberta Is about, one adult in 30 and the Canadian average is one in 20. Dr. Worth told delegates to the Alberta Association for Con- tinuing Education annual con- vention the department plans to mount a province wide adver- tising and public relations scheme to publicize individual local The theme of the program would be "Keep Growing." FREE YEARS The department also plans to provide "12 free years of basic education" for persons of all ages, he said. This basic education program would be available to even' AI- bertan. Talks were planned with Edu- cation Minister Lou Hydman "to see if some of the financial limitations concerning adult? can be removed from the school i foundation regulations." I The department hopes to achieve this goal within the next 12 months. Dr. Worth said. He also said his department has no intention of removing I i continuing education programs 1 from universities. i ''We reject, that suggestion be- cause it offends our concept of local autonomy of education di- versity of co ordination and communication. People of this province have the right of ac- cess to the resources of the uni- versity." The department is consider- ing financial support of non- credit courses offered by post- secondary institutions. It now helped pay for these evening courses through local s c o o 1 boards. U gaud a com pensation seen Ottawa topic LONDON (CPt Foreign Secretary Sir Alec Douglas- Home said yesterday the prob- lem of compensation for Ugan- dan exiles might be the main point of controversy at the Commonwealth prime minis- ters conference in Ottawa in August. Asked about, the conference. said: "I see no subject of particular controversy although I must make a reservation as f.'.r as Uganda is concerned." He said there is no sign of compensation forthcoming from the Ugandan government of Gen. Idi Amin for Asians and Europeans recently forced to leave the country, many leaving their businesses and other pos- sessions behind. He did nol elaborate. Douglas-Home was answering questions after addressing a luncheon meeting of the Diplo- rn a t i c and Commonwealth Writers' Association. In his speech, he said "change is in the air" after more than 25 years of com- parative rigidity in the pattern of international relations. He mentioned the enlarged European Common Market and the growing incluence of Eu- rope, the new role of China in world affairs, the growing strength of Japan and moder- ation in East-West relations. Although British policy was adaptable and flexible, its basic foreign policy remained un- changed, devoted to "the estab- lishment of a strong unified Eu- rope and the maintenance of a close and friendly relationship between Europe and the United States." work, ond added that if their experiments do indeed indi- cate that serum from blacks does help certain cancer patients, it would be possible to treat both potential and actual victims. "Potential" victims of this and other types of cancers may be detected while the tumors are exceedingly small, and thus much easier to treat, if another part of the Hell- Strom's research develops, Serum sign Basically, they have discov- ered that the "blocking anti- bodies" can be fovnd in a potient't blood serum before o tumor con be detected by any other means. At this time, however, such tests are ex- tremely complicated, time consuming and expensive. "Before anything else, the strategy should be to simplify the very complicated tech- niques we are Dr. Karl Hellstrom said. Although the Hellstrbm's be- lieve that this type of test looks promising, they note thqt their studies thus far have been small and much brooder studies are needed before anyone even begins to think about mass screenings of 'he public. The hellstroms' findings suggest that if physidoni ten improve a patient't anti- tumor reactions without creasing the blocking anti- bodies, or if the blocking anti- body's effect can be decreet- ed without affecting anti- tumor activity, there will therapeutic benefits for mony cancer patients, 4 MAZDA ROTARY, AGAIN.
