multinationals and health: reflections on the seveso catastrophe.on july 10, 1976, a cloud of vaporized products containing dioxin escaped from a deposit of a plant of the icmesa firm in the northern suburbs of milan. the fallout was deposited on a vast zone in the municipalities of desio, seveso, meda, and cesano. dioxin was not the desired product of the industrial process, but rather an impurity which generally accompanies trichlorophenol, and, to a smaller extent, the products synthesized from trichlorophenol. among these there are hexachlorophene and the ...1978103846

epidemiology and toxicology of arsenic poisoning in domestic animals.arsenic poisoning is one of the more important causes of heavy metal poisoning in domestic animals. two species--dogs and cattle--are intoxicated more frequently than other animals; yet sporadic instances of poisoning have been observed in cats, horses, and pigs. cases observed by veterinary clinicians are either peracute, acute, or chronic intoxications. frequently the initial and only indication that a severe problem exists with peracute poisoning in a cattle herd is dead animals. chronic into ...1977908297

evaluation of granulocytic ehrlichiosis in dogs of missouri, including serologic status to ehrlichia canis, ehrlichia equi and borrelia burgdorferi.canine granulocytic ehrlichiosis was diagnosed in 37 dogs by finding ehrlichial morulae in 0.1 to 26.2% of their blood neutrophils and eosinophils. all 37 dogs had clinical signs of arthritis or muscular stiffness. titer to ehrlichia canis was determined in sera from 31 of the 37 dogs; 25 dogs had titer ranging from 1:20 to 1:5,120. in the other 6 dogs, titer to e canis was less than 1:10. the most common hematologic abnormality in these dogs, other than rickettsiemia, was thrombocytopenia. gran ...19921539918

project outreach: organizations unified to reach youth.youths of today are forced to deal with the external pressures of alcohol and drug abuse on all levels-from the older youngsters across the street pressuring them to be "cool," to the "cute dog" enticing them with the glamour of being the original "party animal." through today's mass communications, young people are exposed to negative, self-destructive attitudes. it is important, therefore, to expose them to a more positive influence and try to reach them through parental guidance, personal con ...19892493666

bats, cats, and rabies in an urban community.bats are the primary vectors of rabies in humans in the united states. in the urban environment they generally are found within buildings where they may bite people or be attacked by cats or dogs. given the high probability that any bat that bites a person may be rabid, antirabies prophylaxis should be administered as soon as possible after the incident. this should not be delayed pending laboratory results on the bat. children should be taught to avoid contact with moribund bats. cats are more ...19938211327
host-feeding patterns of aedes albopictus (diptera: culicidae) at a temperate north american site.precipitin tests and elisa were used to investigate host-feeding patterns of 172 blood-fed aedes albopictus (skuse) collected at potosi, mo, during the summers of 1989 and 1990. one hundred ten (64.0%) mosquitoes had fed on mammals, 29 (16.9%) on birds, and none on turtles or snakes. thirty-three (19.2%) mosquitoes failed to react in all tests. eighty-six (78.2%) of the 110 mammalian feeds were positive for lower taxa as follows: rabbit, 24.5%; deer, 14.5%; dog, 13.6%; human, 8.2%; squirrel, 7.3 ...19938433336
