Oakland Tribune (Newspaper) - August 13, 1969, Oakland, California eaktinbitfcCribune Wed., Aug. New Hope on Leukemia Gnarled redwood may be oldest living tree in Eastbay Original Redwood Here The only known survivor of (he magnificent redwood grove which once covered the Kastbiiy hills has been found in Oakland. Naturalists and hist o- rians had long ago conclud- ed that not a single one of the thousands of coast red- woods which once grew in the Oakland-Berkeley hills had been spared the wood- men's axe. But Oakland Park Xatur- alist Paul Covel spotted the twisted sequoia sopervirens on an isolated, rocky oul- c r o p p i n g above in llcCrea Memorial Park several months ago. Glen Slrouse of the Hum- boklt State College forestry depart mcnl was brought, in and took tiny core sam- ple from the tree. Micros- copic examination of the growth rings show it is 415 to 420 years old. All other red- woods in the Kastbay are second growth, almost all less than 100 years old. Descriptions of the origi- nal redwoods indicate it was one of the finest stands of redwoods on the West Coast. The periodic fires which ravaged the Gold Hush boom town of San Francis- co a century ago created a demand for timber. The Kastbay hills were logged. Only a few of the stumps of the virgin forest still re- main, and until Covel made his find, it was gen- erally accepted that every single virgin redwood had been logged. Covel said the "inacces- sible location and twisted shape" probably made it unprofitable for the loggers to take it down. It is an exceptionally dif- ficult scramble up the rocky, brush covered hill to the tree, but it can be seen by walking up the canyon extending eastward Leona Lodge in McCrea Memorial Park, at Carson S t r e e and the Warren l-'recwav. NKW YOltK i IT! i Soviet scientists have reported to lheir Western colleagues a bold aiii! promising experi- ment with that inevitably le- thal scourge of children, acute leukemia. The experimental subjects were 12 children in the ad- vanced stages of this blood cancer. They were paired and live leukemia cells taken from each member of each pair were injected into the pair- mate. The Idea was to stimulate their defensive chemistries against the injected cells. The hope was that enough of (his anti-leukemia defensive activ- ity would be left over to at- tack their own leukemia cells. The risk was that defensive chemistries would be indiffer- ciii in die Miimilaijon. In that ease the injected cells would proliferate and haslen death. Hut i! seemed to work, the lUtssians told Western cancer scientists. Levels of leukemia cells in peripheral blood dropped from to 89 per cent to.from zero to Id per cent. Kight of the children have been in "remis- sion" from their disease for more .six months In cancer science any im- provement in the leiikemic conditon is called a remission, since it is incurable. Three of the eight children went into "complete remission." mean- ing 1 e it k e m i c cells disap- peared entirely from the peri- pheral blood. American cancer scientists queried by United Press Inter- national were i m p r e s s e d though mindful that remis- sions in leukemia are not un- common. They are sometimes produced with drugs and they occur spontaneously. Nevertheless remissions brought about by immunologi- ral means are promising and should greatly s t i m u 1 a t e scientific interest in the im- mtinologic approach lo cancer in general and leukemia in particular, t h e s e scientists said. This approach was once considered a probably answer to cancer because it involves the powerful defensive body chemistry which attacks any- thing "foreign" to the body. It "rejects" hearts and other transplanted organs and is why people don't have most viral and bacterial diseases more than once. Hut manv efforts over manv years to it against cancer have been disappoint- ing and many scientists have concluded that cancers are tmt "foreign" to the bodies in which they arise and hence do not rouse 'defensive imiminolo- gic chemistry. certainly all their 12 leu- kemic e h i 1 d r e n were "t o I or a nt" of their own leukemia cells, the Russians reported to Western scientists through the British Science Journal. Nature. Their blood chemistries were being over- whelmed by letikcmic prolifer- ation, despite drug treatment. Hut, they reasoned, "for- eign" leiikemic cells could stimulate a defensive reaction against both foreign and na- tive leukemic cells since they most probably had many mu- l u a 1 "determinants.'' Each child was paired with a child whose leukemia was of dif- ferent type. i The principal Kussian scien- tist was Dr. S. V. Skurkovich of the Central Institute of HP- matology and Wood Transfu- sion, Moscow. His collabora- tors were N. S. Kisljak. L. A. Machonpva and S. A. Begun- enko of the Second Moscow Medical Institute. The Russians detailed their experiments in ways to per- mit Western scientists to fol- low whatever leads (hat at- ract them.
