Use of Telazol to immobilize female northern sea lions (Eumetopias jubatus) in Alaska.

Twenty-nine female northern sea lions (Eumetopias jubatus) were immobilized using Telazol in dosages ranging from 1.8 to 8.1 mg/kg. Best results were achieved with Telazol dosages ranging between 1.8 and 2.5 mg/kg which resulted in smooth induction and recovery. Optimal injection location was in the muscle mass of the lower back and hip. Dosages greater than 3.5 mg/kg resulted in a tendency toward hypothermia. Six mortalities occurred which were partially caused by the location of drug injection and perhaps the high dosage.

Viral serologic survey of bowhead whales in Alaska.

Serum samples from 21 of 36 Eskimo harvested bowhead whales (Balaena mysticetus) were positive by virus neutralization (50% endpoint titer > or = 1:28 and/or 100% endpoint titer > or = 1:20) for antibodies to at least one virus serotype from the calicivirus family, vesicular exanthema of swine virus (VESV) and San Miguel sea lion virus (SMSV). Many animals were positive to more than one serotype when using the Spearman-Karber (S-K) method for calculating antibody titers. The most common serotype detected was VESV F55 with 6 of 36 (17%) by the Monto and Bryan (MB) titer calculation method, and 17 of 36 (47%) by the S-K titer calculation method. Vesicular exanthema of swine virus 1934B antibody was detected in 3 of 36 (8%) and 5 of 36 (14%) whales using the MB and S-K methods, respectively. Vesicular exanthema of swine virus J56 antibody was detected in 3 of 36 (8%) by the S-K method only. All whales < 8.5 m (estimated yearlings, n = 6) were seronegative for VESV J56 and 1934B while 10% and 17% of the whales > 8.5 m were positive, respectively. Whales assumed to be sexually mature (> 13 m) had a higher prevalence of antibody to VESV 1934B and SMSV 8 than those < 13 m. Gender had an effect on seroprevalence of antibody to VESV 1934B as titers > or = 1:28 (S-K method) occurred in 18% of the females and 7% of the males. Antibody to other serotypes (SMSV 8 and 12) occurred less frequently (< 6%) at an antibody titer > or = 1:28 by the S-K method. All 36 whale sera were negative for antibody to VESV-A48, B51, C52, D53, E54, G55, H54, I55, and K54; Tillamook calicivirus, and dolphin morbillivirus; and SMSV-1, 2, 4, 5, 6, 7, 9, 10, 11, and 13 by the S-K method.

Ooligan grease: a traditional food fat of western Canada and Alaska.

First Nations Peoples prepare ooligan grease by ripening several tons of the small fish, Thaleichthys pacificus, and rendering the fish oil. Eighteen samples from different family preparations of five cultural areas were analyzed for a spectrum of nutrients, organochlorines, and heavy metals. Ooligan grease was found to be a rich source of retinol (2444 +/- 1198 RE/100 g) and n-3 fatty acids, but had less vitamin A compared to fat of raw fish. There was a 10-fold increase in n-3 fatty acids in grease compared to raw fish fat, which may be attributed to microbial conversion of other fatty acids to DHA. Whole fish were good sources of Ca, Fe, and Zn; heavy metals were below guideline levels in grease. Chlorinated pesticides and PCB increased from north to south locations in British Columbia, with mean levels being 110 ng/g lipid of total chlorinated pesticides and 30 ng/g lipid of PCB. These levels are below regulation limits established by Health Canada. It is concluded that ooligan grease is a superior food fat and safe for human consumption.

The effect of an alcohol ban on the number of alcohol-related hospital visits in Barrow, Alaska.

PURPOSE: This study was conducted to examine the impact of a change in local alcohol laws on alcohol-related hospital usage. Heavy alcohol consumption and its complications are major health problems in the Arctic. For many years, the sale of alcohol in Barrow was illegal, i.e., "damp" status. In October 1994, the residents of Barrow voted to make both the sale and importation of alcohol illegal, i.e., "dry" status. METHODS: The Public Health Service Hospital in Barrow is the only physician-staffed health care facility for 4,000 residents in Barrow, as well as for five of its seven outlying, dry villages (approximately 2,000 more residents). We retrospectively studied the number of alcohol-related outpatient visits to our hospital from November 1993 through October 1994 (the damp year), and from November 1994 through October 1995 (the dry year). The data used were from the emergency visit log in our outpatient department. RESULTS: We found a 76.5% to 93.2% decrease in alcohol-related outpatient visits when comparing corresponding months during the dry year to those during the damp year. The average overall decrease in alcohol-related outpatient visits was 84.7%. These results were highly significant with a p-value of 0.0022. We conclude that the prohibition of alcohol in remote areas can be an effective method in reducing the amount of alcohol-related health problems and can help make a healthier community.

Methodological issues in evaluating a culture-based substance abuse treatment program in the Kuskokwim Delta, Alaska.

This paper presents a rationale for using videotape records in evaluation research. Although videotaping is commonly used in ethnographic and sociometric analysis, the evaluation literature does not show the application of these recording techniques to program evaluations. The authors outline a model for exploring the effectiveness of video in qualitative program evaluation.
