effects of the chernobyl accident on animal husbandry and production, from a swedish perspective.about 20% of the swedish land area was considerably contaminated by radionuclides released by the nuclear accident at chernobyl, ukraine, in april 1986. however, less than 10% of the arable land was contaminated. the heavy contamination was closely correlated with the amount of rain received during the first days of may 1986. immediate restrictions on grazing limited the early uptake of contaminants in animal products. changes in management of animals, especially sheep, goats, and reindeer in th ...19892703422
the impact of low carbohydrate consumption on glucose tolerance, insulin concentration and insulin response to glucose challenge in dogrib indians.the nddg and the who recommend that individuals undergoing an oral glucose tolerance test (ogtt) consume a minimum of 150 gm of carbohydrate on each of three days preceding the ogtt. carbohydrate restriction affects the diagnostic accuracy of the ogtt. this is a problem for the diagnosis of diabetes among northern peoples, but may also have relevance for other amerindians. dogrib indians of the canadian nwt still rely on the traditional dietary, based on caribou-hunting and fishing. the impact o ...19892671575
arctic life adaptation--ii. the function of musk ox (ovibos muschatos) hemoglobin.1. the hemoglobin system from musk ox (ovibos muschatos) has been characterized from the functional point of view with special regard to the effect of organic phosphates and temperature. 2. the results are similar to those previously obtained in the case of reindeer and confirm that hemoglobins from arctic animals may display very low enthalpy change for the reaction with oxygen. 3. this finding is considered an example of molecular adaptation of respiratory pigments to extreme environmental con ...19892598629
arctic life adaptation--i. the function of reindeer hemoglobin.1. the functional properties of hemoglobin from the reindeer (rangifer tarandus tarandus l.) are characterized as a function of ph, temperature and organic phosphate concentration. 2. alongside overall similarities shared with most vertebrate hemoglobins, hemoglobin from the reindeer shows significant differences with respect to the effect of both organic phosphates and chloride anions. 3. the limited effect of temperature on oxygen binding (delta h = -4 kcal/mol o2) could be regarded as an inte ...19892598627
the epidemiology of echinococcus granulosus in great britain. v. the status of subspecies of echinococcus granulosus in great britain.twenty-five years ago williams and sweatman suggested that in great britain there are two subspecies of echinococcus granulosus--e. granulosus granulosus and e. granulosus equinus. echinococcus granulosus granulosus does not mature either in foxes or in horses: e. granulosus equinus will mature in either. the prepatent period of e. granulosus granulosus in the definitive host is about 42 days while that of e. granulosus equinus is about 70 days. each subspecies has a characteristic morphology. m ...19892596902
variation in cadmium content of caribou tissues from northern québec.samples of kidney, liver, skeletal muscle, heart, mesentery and rumen wall were collected during 1985-1986 in northern québec from 121 caribou belonging to the rivière george herd. significant seasonal variations were found for cadmium concentration in kidneys, liver and skeletal muscles, the level being higher in winter than in autumn. the concentration in liver and kidneys increased with age, while the effect of this factor was complex in skeletal muscles. sex-related differences were found in ...19892569761
brucellosis in an inuit child, probably related to caribou meat consumption.a 9-year-old inuit boy with brucellosis is presented. the most likely source of his infection was contaminated caribou meat. brucella suis is enzootic in canadian caribou herds and this case indicates that natives of the arctic are a risk group for acquiring brucellosis through the ingestion of raw caribou meat.19892569231
evaluation of xylazine hydrochloride as the sole immobilizing agent in moose and caribou--and its subsequent reversal with idazoxan.xylazine hydrochloride was used as the sole immobilizing agent in moose and caribou. the animals were free-ranging and immobilization was accomplished from a helicopter using powered darts. following a period of immobilization during which radiotelemetry collars were fitted, the animals were revived using idazoxan (rx 781094) or its methoxy analogue rx 821002. xylazine was administered at dose rates of approximately 3.0 mg/kg and 5.0 mg/kg to the moose and caribou, respectively. moose received 4 ...19892563404
can zeolites decrease the uptake and accelerate the excretion of radio-caesium in ruminants?the zeolite group of minerals has been suggested as a means of decreasing the uptake of radio-caesium by humans and domestic animals, and also to accelerate the excretion of radio-caesium which has already been absorbed. artificial mordenite, one of the zeolites being considered for this purpose, was dispersed in liquid paraffin and administered to goats and lambs fed radio-caesium-contaminated hay. faeces and urine were collected separately and analyzed by gamma spectrometry on each day of the ...19892538920
