Ao - Friday, November 2, 1984 - North Shore News Ge editorial ; News Viewpoint A dark shadow errorism, as U.S. Secretary of State Shulz has emphasized, is becoming one of the biggest threats to Western democracies. The murder of Indian Prime Minister Indira Gandhi is one more grim con- firmation of his warning. Aside from the human tragedy, the political repercussions for the world’s largest democracy and its global partners could be in- calculable. The same would be true if the bomb attempt on the life of Britain’s prime minister, Margaret Thatcher, a few weeks earlier had succeeded. There are too many similar examples over recent years—including the assassinations of President Kennedy, his brother Robert and the Queen’s uncle, Lord Louis Mountbatten—to allow. Even when thwarted, the terrorist leaves his dark shadow over the democratic way of life. The elaborate security precautions taken nowadays to protect world figures severely limit their direct contact with people, as well as disrupting for periods public freedom of movement and costing huge sums of money for the hundreds of security personnel involv- ed. President Reagan’s brief opening of the Los Angeles Olympics (behind bullet-proof glass) and the guarding of the Pope during his Canadian visit are just two instances, fresh in memory, of how the terrorist intervenes to separate democratic leaders from their followers. Secretary of State Schulz believes still tougher security measures and techniques, in- fringing even more on the liberties of law- abiding citizens, are ultimately the only way to defend democracy against the terrorist threat. In a sense, this means the terrorist has already half won. Society may have to accept that fact in order to deny him total victory. Parks are QURS opefully, the provincial Parks Branch will have its act together tomorrow to prevent a repetition of last weekend's fiasco when thousands of Lower Mainland citizens were denied access to their own mountain parks. Privatization of ski facilities at Cypress Bowl and Mt. Seymour doesn’t alter the fact that the parks themselves are public property. The government is still responsible, one way or another, for ensuring the roads to the top are kept clear. $2 VOOOR OF OTIS am WHET WARCOUWER Display Advertising 980-0511 north shore Classitied Advertising 986.6222 news Newsroom 985 2131 HERTS TMT yy wErrsenyes Circulation 986 1337 Subscriptions 985 2131 1139 Lonsdale Ave. North Vancouver BC V7M 2H4 Publisher tere fren ok Associate Publisher Editor in Chiet Advertising Utrector SS RS ine THE PROCESS OF REBULDING STARTS... Drugs pose double hazard RUG ADDICTION may involve two pro- cesses, the result of the drug’s action on two distinct regions of the brain, suggest resear- chers at Montreal’s Concordia University. Their results may necessitate changes in addic- tion treatment programs, which have usually treated one of the processes bul not the other Doctors Michael Bozarth and Roy Wise, of Concor dia’s Centre for Studies in Behavioral Neurobiology, studied the effects on rats of drugs called opiates, which include heroin) and mor phine Uhey found that the drugs can, produce both ‘reward behavior’ and physi cal dependence by stimulating different areas of the brain Reward behavior is distinct from dependence dn reward behavior an animal whose body does not actualls tcly physteally upon a drug (dependcnve) takes the drugy because i paris pleasure ty By DAN CASS classic “withdrawal” signs ex hibited by the animal upon discontinuing the drug chat- tering teeth, shaking, and so on Reward behavior alone is not accompanied by withdrawal symptoms The researchers minute these injected volumes (one ten thousandth of a miadblitee) ot morphine directly mto two speaitae areas of the rat's brain the ventsal tegmentum (VT) and the periventricular gicy region (POR) The behavior of the tats pomled toda fundamental difference between these two ALC Aas Rats that were tart dependent on the drug learn cd to press a lever un return tor a mocphine myection ate the VE. but not inte the PeoR On the other tak s were hand. made oo plrvsialty dependent by injections of morphine into the PGR, but not by injections into the VT. The researchers concluded that the ventral tegmentum was responsible for reward behavior, whereas the PGR was responsible for dependence. The two func- tions appeared quate distinct, despite the fact that these two regions are separated in the rat's brain by only two millimetres “What is new about our work is that we demonstrated rewarding effects of opiates ingected directly into the brain. said Dr Wise The experiment showed that reward and dependence are not only distinct behaviors but also rely on anatomically separate parts of the brain, he says Sorcntists have Known for almost JO vears that reward and dependence are tndepen dent behaviors But i was thought that physrologie ally they omipht be tangled together like telephone lines atooa tage Swoite board Dr. Wise explains. ‘‘Using very small injections directly into the brain allowed us to determine that these two mechanisms are not tangled together in the brain, they are quite completely separated.’’ Dr Wise says the Concor dia study, together with previous studies on the behavior distinctiveness of reward and dependence, pro ves that many drug addiction treatmént programs should change their emphasis “*“Many (reatment pro grams stress) detoxification the breaking of the dependence cycle This, alone, does not) work very well, since opiates are still powerfully rewarding, even for the detoxified patient. he says “What this all means for the therapist is that until the detoxified ex addicts teamed to find satis fying pleasure elsewhere an life, he as far sources of from cured (Cunadian Sctemee News Ha ate an Myo OW whe “ace wae 't Porsonnel Director Classified Manaygo: Circulation Direc tur bbe ee va or beer RA @ a Produc thon Otrec tor Photoyr raphy Manage: North Shore Nows " " , » en ete 4 howe 6 ve rn ' woos Ned os , a Ve PSYC HOT OG sd fuvetaa ‘Strbieres rt rer in theo, re wey be cages abet vie be tags oe “ Petive scetente Uinavecrsity says the treatment of tenon ad a Wistress tera Dra oti te 1OH4 North Shore bree Miema itd Al ghts ‘enerved bey pe SOr Gof oth Non "y . . * cs ett . dhotsoan Noorth Nien rs Cormpaatable te ¥ " " ’ roe tte gy Waret bee ttre aed preatterertt of teh hk soca thre Notre tte ain Ssoorthy SOO cat re Net tt be wee Phe vested to. . ro. ste Yon | jee Chit cett eter va tae rt tbr Ne prertiat tooled epee fhe ert ce ape ab dene rrey bee coreSPeucud va me puative net Phe _ {> hh ty .
