LAST WEEK's leak of toxic gas in Somerville after a railroad crash did more than irritate eyes--it set to rest the misguided notion that it is somehow possible to evacuate an urban area quickly in an unanticipated emergency...
...phosphorous trichloride gas released in the accident apparently injured few seriously. But had it been something else--say radiation released from a nuclear plant in the case of a meltdown--the damage would have been incalculable. Radiation would be much harder than toxic gas to combat--on Thursday, at least, workers had a clearly visible localized cloud. Those in danger could smell the gas, and there were comparatively safe places to flee, refuges that would be much harder to find in the event of radiation release. Thursday's accident demonstrated Boston's--and any other city's--vulnerability...
...railroad tank car rupture in Somerville sent a huge white cloud of toxic gas drifting over parts of that city, Cambridge and Boston yesterday, forcing thousands to flee their homes and jobs, and sending 100 victims to local hospitals. local hospitals...
...start in just one of the body's billions of cells, triggered by a stray bit of radiation, a trace of toxic chemical, perhaps a virus or a random error in the transcription of the cell's genetic message. It can lie dormant for decades before striking, or it can suddenly attack. Once on the move, it divides to form other abnormal cells, outlaws that violate normal genetic restraints. The body's immune system, normally alert to the presence of alien cells, fails to respond properly; its usually formidable defense units refrain from moving in and destroying the intruders. Unlike...
...into boosting its own manufacture of IF by injecting inducers, usually double strands of synthetic RNA* that resemble viruses. The method was tried in the 1960s by Maurice Hilleman and others at the Merck Institute. But inducers were virtually abandoned when they proved largely ineffective and, on occasion, highly toxic. A new inducer, though, has been showing some promising early results...
