| noise and hearing loss in reindeer herders. | air conduction hearing thresholds were examined in 512 reindeer herders (aged 18-65 years, clinically normal ears) to evaluate the prevalence of noise-induced hearing loss. the hearing thresholds at 6 khz showed significant noise-type impairment of hearing compared with those in the iso 7029 standard or a finnish reference population. the subjects were exposed to noise mainly in the use of snowmobiles and chain saws: daily noise exposure ranged from 93 to 104 db(a). the age adjusted hearing thre ... | 1994 | 7710590 |
| combined effects of cold, vibration and smoking, particularly in snowmobile users. | in a living and working environment more than one factor is usually important for physiological and psychological responses in the body. in this report the effects and combined effects of hand-arm vibration and cold, in particular their effect on frostbite, has been reviewed. as a second example is given the combined effect of vibration and smoking on vibration-induced white finger. in both cases our previous work among reindeer herders frequently using snowmobiles has been utilised as an exampl ... | 1994 | 7710589 |
| hand-arm vibration in snowmobile drivers. | hand-arm vibration was measured on the handlebars of snowmobiles (n = 29) and a postal inquiry was made among reindeer herders, n = 2,705. since many subjects had used also other vibrating tools a snowmobile group proper (n = 334) was established, and in this group 18% of the subjects reported that they had experienced white finger attacks and 48% numbness of the hands. the age-adjusted prevalence of the white finger syndrome was more than three times higher in the snowmobile group than in the c ... | 1994 | 7710587 |
| chromosome aberrations in norwegian reindeer following the chernobyl accident. | chromosome analyses were carried out on peripheral blood lymphocytes of semi-domestic reindeer in norway which had been exposed to varying amounts of radiocesium emanating from the chernobyl accident. the sampling was done in the period 1987-1990. the material included 192 reindeer, originating from four herds in central norway, an area considerably affected by fallout from the chernobyl accident, and from three herds in northern norway which was unaffected by fallout from the accident. signific ... | 1995 | 7700280 |
| a rapid method for the determination of radioactive caesium in live animals and carcasses, and its practical application in norway after the chernobyl nuclear reactor accident. | a technique was developed for the measurement of levels of caesium radionuclides (137cs + 134cs) in live reindeer, cattle, and sheep and in carcasses from these species. the instrument used was a sodium iodide scintillation detector coupled to a portable multi-channel analyser. based on a combination of background measurements and measurements of impulses from animals with the detector in different anatomical positions we recommend the following procedures: lamb: the detector placed on os sacrum ... | 1994 | 7676924 |
| microbiological contamination of reindeer carcass during slaughter. | microbiological counts for 10 different sampling sites of 28 reindeer carcasses were studied in 3 reindeer slaughterhouses in finland. on each carcass the hindshank, round, abdomen, flank, brisket, foreleg, shoulder, neck, foreback and back were sampled immediately after slaughter, using a non-destructive swabbing method. the overall mean bacterial count for 10 sampling sites of reindeer carcasses was 1.51 +/- 0.51 log10 cfu/cm. statistically significant differences were detected between samplin ... | 1994 | 7676921 |
| body fat distribution and other cardiac risk factors among circumpolar inuit and nganasan. | secular trends in skinfold thicknesses and body fat distribution were examined in the adult inuit of igloolik, n.w.t. through surveys conducted in 1969/70, 1979/80 and 1989/93. findings were compared with the nganasan population of volochanka (taimir peninsula, siberia), who were examined in 1992/3. the skinfold readings of the inuit have increased over the two decades of observation. currently, the young male inuit and nganasan remain relatively thin, but older inuit men and the women of both p ... | 1995 | 7669126 |
| influence of route of administration on the plasma concentrations of ivermectin in reindeer. | the concentration of ivermectin in the plasma of reindeer was measured after it was administered either topically as a pour-on preparation at 500 micrograms kg-1 bodyweight at different seasons to animals of different ages, or after subcutaneous and oral doses of 200 micrograms kg-1 bodyweight. the plasma concentrations of ivermectin were highest and least variable after it was administered subcutaneously. | 1995 | 7659858 |
| determination of aluminium in liver from reindeer, moose and sheep by electrothermal atomic absorption spectrometry. | aluminium in liver from reindeer, moose and sheep from the northeast part of norway was determined by graphite furnace atomic absorption spectrometry following digestion of the samples with nitric acid. the concentration of aluminium in the liver was markedly higher for reindeer than for moose and sheep; the median values obtained were 0.56 microgram g-1 al (wet wt.) for 101 reindeer, 0.06 microgram g-1 al for 72 moose and 0.09 microgram g-1 al for 40 sheep. the detection limit of the method was ... | 1995 | 7644911 |
| the temperature threshold for development of elaphostrongylus rangiferi in the intermediate host: an adaptation to winter survival? | to test the hypothesis that the relatively high developmental temperature threshold of the parasitic nematode elaphostrongylus rangiferi in the intermediate snail host is an adaptation to minimize larval mortality during winter, an experiment was set up in which snails of the species arianta arbustorum were experimentally infected with the parasite. the snails were divided into 3 groups known to contain 1st, 2nd or 3rd-stage larvae, and incubated at 3 degrees c for an experimental period of 18 w ... | 1995 | 7609984 |
| [the effect of different types of species-specific acoustic signals on the rate of mammalian cardiac contractions]. | experiments with rodents and even-toed ungulates show that significant changes in the heart rate (hr) in response to administration of species-specific sound stimuli occur only under conditions of deficiency of useful information. cardiac response depends mainly upon the type of the signal, ecology and physiology of the animal-recipient. in mammals living in colonies and herds in the open (ground squirrels, reindeer) hr changes become conspicuous only under conditions excluding acquirement of vi ... | 1995 | 7597827 |
| assessment of dietary exposure to trace metals in baffin inuit food. | chronic metal toxicity is a concern in the canadian arctic because of the findings of high metal levels in wildlife animals and the fact that traditional food constitutes a major component of the diet of indigenous peoples. we examined exposure to trace metals through traditional food resources for inuit living in the community of qikiqtarjuaq on baffin island in the eastern arctic. mercury, cadmium, and lead were determined in local food resources as normally prepared and eaten. elevated concen ... | 1995 | 7588487 |
| ruminal microbial digestion in free-living, in captive lichen-fed, and in starved reindeer (rangifer tarandus tarandus) in winter. | in free-living (fl) reindeer eating a natural mixed winter diet dominated by lichens, captive (cf) reindeer fed pure lichens ad libitum, and cf reindeer subsequently starved for 1 day (cs1 reindeer) or 4 days (cs4 reindeer), the dominant rumen anaerobic bacteria were characterized, their population densities were estimated, and ruminal ph and volatile fatty acid concentrations were determined. in the fl reindeer, the total median viable anaerobic bacterial population ranged from 18 x 10(8) to 35 ... | 1995 | 7574599 |

| [genetic polymorphism of the amylases found in species of artiodactyla by means of polyacrylamide gel electrophoresis]. | three different types of isoenzymes, am1, am2 and am3 have been revealed by polyacrylamide gel electrophoresis (pag) and affine pag electrophoresis in artiodactyla. in cattle and pigs am2 isoenzyme is monomorphic, as shown by pag electrophoresis, and polymorphic in affine gel separation (two alloenzymes, am2a and am2b have been revealed). some of sheep have no am2 isoenzyme, which, apparently, account for the presence of minus-allele. am2 isoenzyme was not detected in saiga tatarica which are re ... | 1983 | 6189765 |
| the structure and insulation properties of the reindeer fur. | the structure of the fur of the reindeer (6 adults, 4 calves) was studied with light and scanning electron microscopy and skin and rectal temperatures were measured in 216 living animals at varying ambient temperatures (-28 to +15 degrees c) and also on excised skin samples in the laboratory (temperature range -20 to +20 degrees c, wind 0 or 10 m/sec, 5 different directions). guard hair count and length varied according to the site of excision and were on average 2000/cm2 and 12 mm on the forele ... | 1984 | 6150798 |
| effects of nutrition on seasonal changes in testosterone levels in young male reindeer (rangifer tarandus tarandus). | food restriction during autumn in male reindeer calves decreased peak testosterone levels at 4-6 months, and also at 16-17 months of age. peak testosterone levels at the age of 16-17 months were significantly correlated to body weight at 6 months but not to body weight at 16 months of age. there were small secondary testosterone peaks (1-3 ng/ml) in march or april in 11 of 16 animals. testosterone levels started to increase before summer solstice in 50% of the yearlings. | 1984 | 6143638 |
| fibre composition and enzyme activities in five different muscles from the svalbard reindeer. | beta r fibres (type i) constitute less than 10% of the semimembranosus and longissimus dorsi muscles and about twice as much of the gluteobiceps and flexor hallucis. except for longissimus dorsi, 50% or more consist of alpha w (type iib) fibres--in semimembranous, as much as 70%. despite the comparatively large content of alpha w fibres, both the oxidative capacity and the capacity to metabolize fatty acids is high. furthermore, unexpectedly small differences in oxidative capacity between the th ... | 1984 | 6141034 |
| serologic survey for selected microbial pathogens in alaskan wildlife. | antibodies to brucella spp. were detected in sera of seven of 67 (10%) caribou (rangifer tarandus), one of 39 (3%) moose (alces alces), and six of 122 (5%) grizzly bears (ursus arctos). antibodies to leptospira spp. were found in sera of one of 61 (2%) caribou, one of 37 (3%) moose, six of 122 (5%) grizzly bears, and one of 28 (4%) black bears (ursus americanus). antibodies to contagious ecthyma virus were detected in sera of seven of 17 (41%) dall sheep (ovis dalli) and five of 53 (10%) caribou ... | 1983 | 6139490 |
| relationships between hormone-induced and compensatory weight changes in reindeer (rangifer tarandus tarandus). | 1. in connection with a study of hormonal effects on food consumption in reindeer, weight changes during treatment were compared with weight changes during a 3-week period following treatment. 2. rates of weight change during the post-treatment period were inversely proportional to induced weight changes. 3. this inverse relationship is interpreted as evidence for a functional set-point for body weight in reindeer. | 1983 | 6130882 |
| prediction of 90sr body burdens and radiation dose in anaktuvuk pass alaska eskimos due to fallout. | strontium-90 concentrations in skeletons of eskimo residents of anaktuvuk pass. alaska during 1954-79 were predicted from two models based on (1) sr kinetics in human bond and (2) estimated annual 90sr ingestion rates via caribou meat. predicted skeletal burdens of adult eskimos gradually increased through 1961 and then rapidly achieved maximal values during 1964-66, reflecting fallout 90sr levels in caribou meat which contributed 80-97% of dietary 90sr intake. concentrations of 90sr in male esk ... | 1982 | 6129202 |
| conglutinin, immunoconglutinins and heterophile antibodies in the sera of apparently healthy moose (alces alces) and caribou (rangifer tarandus) in quebec. | serum samples from apparently healthy wild populations of moose and caribou in the province of quebec, canada were screened for the presence of conglutinin (k), immunoconglutinins (iks) and heterophile antibodies. the conglutinating factor in moose and caribou sera was characterized utilizing the necessity of calcium ions for its reaction with sensitized sheep erythrocytes which had been alexinated with horse complement. the conglutinating substance in these animals did not require calcium ions ... | 1982 | 6127416 |
| 137cs concentrations in northern alaskan eskimos, 1962-79: effects of ecological, cultural and political factors. | concentrations of worldwide fallout 137cs were measured in the lichen-caribou-eskimo food chain of northern alaska during the period 1962-79. pronounced inputs of fallout occurred after major nuclear weapons tests in the atmosphere and 137cs was transmitted through the food chain to eskimos with about a 2-yr delay due to environmental parameters. caribou (rangifer tarandus) meat sampled during spring harvest contained 4 times the 137cs concentration of lichens obtained from their winter range. c ... | 1982 | 6123492 |
