Culture in treatment, culture as treatment. A critical appraisal of developments in addictions programs for indigenous North Americans and Australians.

Indigenous people in Australia and in North America have been creating innovative interventions in the addictions field for several years now--incorporating traditional healing practices and cultural values into otherwise western programs--although this process is more developed in Canada and the U.S. than it is in Australia. Through a process of cultural diffusion, Australian Aborigines have incorporated many ideas from Native Canadian treatment models. As a result, residential treatment utilizing adapted forms of the 12 steps of Alcoholics Anonymous is being promoted by indigenous Australians. This paper examines comparative material on the uses of culture as a form of healing and traces the rationale for the argument that cultural wholeness can serve as a preventive, or even curing agent in drug and alcohol abuse. This is a qualitative leap from the now universally accepted notion that treatment and rehabilitation for native people should be culturally appropriate. There are, however, certain dilemmas confronting native treatment directors attempting these syncretic approaches, given aspects of cultural contexts which can serve to foster drug and alcohol use rather than discourage it. Additionally, North American Indians have at their disposal a rich heritage of communal healing techniques; some (such as the sweat lodge) have been adapted and incorporated into the treatment both of solvent abuse by adolescents, and alcohol abuse by adults. In Australia on the other hand, traditional healing techniques have been less amenable to adaptation. On neither continent are indigenous people attempting to adapt recent mainstream models of intervention to suit their needs (such as Brief Intervention) which is currently receiving international attention in addictions research and treatment.

Indigenous plant remedies in Zimbabwe.

Two household surveys undertaken in Zimbabwe between 1981 and 1983 revealed extensive use of indigenous plant remedies in the home-management of childhood diarrhoea and many adult illnesses. Names of the local plants, trees and shrubs are listed, together with the part of the plant used and the type of condition treated. The usage of medicinal plants underscores the need for further study of indigenous pharmacopoeias and the therapeutic properties of plants. The role of indigenous plant remedies within local health care systems is also worthy of closer investigation.

Biological diversity, indigenous knowledge, drug discovery and intellectual property rights: creating reciprocity and maintaining relationships.

When new plant-derived therapeutics based on indigenous knowledge are being explored, it is important that the pharmaceutical companies return benefits to the native populations and the local governments from which the research material was obtained. When a potentially marketable plant product is being developed, it is essential that equitable agreements have already been established between the pharmaceutical companies and the people and/or countries from which this indigenous knowledge was acquired. Equally important is the commitment to provide immediate reciprocity that will enhance the welfare, the biocultural diversity and the well-being of the forest peoples. These measures should commence when a research project begins and continue during its duration. The development of these measures must be based upon the expressed needs of the indigenous communities. The relationship between the stability of the rain forest biocultural diversity, the creation and development of agro-forest resources and the long term benefits to the forest people is highlighted. Examples of initiatives taken by Shaman Pharmaceuticals Inc. and the Healing Forest Conservancy are described and discussed in the context of exploring appropriate use of intellectual property law to address the ethical issues facing all business and research groups working in the tropics.

The indigenous gastrointestinal microflora.

The indigenous gastrointestinal (GI) tract microflora has profound effects on the anatomical, physiological and immunological development of the host. The indigenous microflora stimulates the host immune system to respond more quickly to pathogen challenge and, through bacterial antagonism, inhibits colonization of the GI tract by overt exogenous pathogens. Indigenous GI bacteria are also opportunistic pathogens and can translocate across the mucosal barrier to cause systemic infection in debilitated hosts.

Effect of indigenous bacterial activity on arsenic mobilization under anaerobic conditions.

Batch biochemical leaching tests were carried out to investigate the mobility of arsenic from a contaminated soil collected from a French gold mining site. The specific objective of this research was to examine the effect of indigenous bacterial activity on arsenic mobilization under anaerobic conditions. In a first step, physical and chemical characterizations were performed to provide data concerning the liquid-solid partitioning and mobility of arsenic and other inorganic constituents. In a second step, batch bioleaching tests were conducted in shaker flasks to determine the effect of indigenous bacterial activity under different anaerobic conditions (i.e., addition of mineral nutrients and carbon sources) on arsenic mobilization. Results indicated that arsenic release during contact with deionized water was limited by its very low solubility in the interstitial solution and by the stability of the different arsenic compounds formed with the amorphous solid phases of the soil (mainly iron (oxy)hydroxides). However, an increased mobilization potential was observed over the long term under anaerobic conditions with indigenous bacterial activity enhanced by the addition of carbon sources.

Influence of plant species on population dynamics, genotypic diversity and antibiotic production in the rhizosphere by indigenous Pseudomonas spp.

The population dynamics, genotypic diversity and activity of naturally-occurring 2,4-diacetylphloroglucinol (DAPG)-producing Pseudomonas spp. was investigated for four plant species (wheat, sugar beet, potato, lily) grown in two different soils. All four plant species tested, except lily and in some cases wheat, supported relatively high rhizosphere populations (5 x 10(4) to 1 x 10(6) CFU/g root) of indigenous DAPG-producing Pseudomonas spp. during successive cultivation in both a take-all suppressive and a take-all conducive soil. Although lily supported on average the highest population densities of fluorescent Pseudomonas spp., it was the least supportive of DAPG-producing Pseudomonas spp. of all four plant species. The genotypic diversity of 492 DAPG-producing Pseudomonas isolates, assessed by Denaturing Gradient Gel Electrophoresis (DGGE) analysis of the phlD gene, revealed a total of 7 genotypes. Some of the genotypes were found only in the rhizosphere of a specific plant, whereas the predominant genotypes were found at significantly higher frequencies in the rhizosphere of three plant species (wheat, sugar beet and potato). Statistical analysis of the phlD(+) genotype frequencies showed that the diversity of the phlD(+) isolates from lily was significantly lower than the diversity of phlD(+) isolates found on wheat, sugar beet or potato. Additionally, soil type had a significant effect on both the phlD(+) population density and the phlD(+) genotype frequencies, with the take-all suppressive soil being the most supportive. HPLC analysis further showed that the plant species had a significant effect on DAPG-production by the indigenous phlD(+) population: the wheat and potato rhizospheres supported significantly higher amounts of DAPG produced per cell basis than the rhizospheres of sugar beet and lily. Collectively, the results of this study showed that the host plant species has a significant influence on the dynamics, composition and activity of specific indigenous antagonistic Pseudomonas spp.

Preventable chronic diseases among indigenous australians: the need for a comprehensive national approach.

Chronic conditions such as diabetes, cardiovascular disease and heart disease represent a serious and escalating health burden for Indigenous populations across Australia. Social disadvantage, inactive lifestyle and poor nutrition are major contributors to chronic disease among Indigenous peoples. We have the knowledge base to reduce the devastating impact of early onset chronic diseases in those who already have the conditions, and to prevent or delay their onset in those who have not yet succumbed. This represents a major and urgent challenge to governments and Indigenous communities.

Indigenous representations of illness and AIDS in Sub-Saharan Africa.

Cultures all over the world have evolved illness representations that can accommodate not only new diseases, but also new epistemologies for explaining disease. This paper examines illness representations in Sub-Saharan Africa, and how these have responded to the emergence of AIDS. Indigenous views of illness (particularly STDs) exhibit coherent structure, in which causation, prevention and treatment relate to one another in functional ways. As an STD, an epidemic, and a disease which leads to premature death, AIDS lends itself readily to accommodation into established indigenous representations of illness. Even biomedical views of causation can be readily incorporated into traditional views of how illnesses are caused. However, biomedical and traditional views concerning prevention appear to be in direct conflict with one another, with potentially hazardous consequences. Research exploring the extent to which indigenous beliefs may be influencing people's decisions about safe sex could offer useful insights for AIDS prevention programs.

The role of indigenous microorganisms in suppression of Salmonella regrowth in composted biosolids.

Composting is commonly used as an effective means of stabilizing wastewater biosolids and reducing pathogens to very low concentrations. However, it has been shown that under certain conditions Salmonella can regrow in previously composted biosolids. Growth of seeded Salmonella typhimurium in composted biosolids ranging from two weeks to two years maturity was monitored. Results from sterile and non-sterile composted biosolids were compared. Seeded S. typhimurium colonized rapidly in sterilized biosolids reaching a maximum population density of more than 10(8) g(-1). Growth of seeded S. typhimurium was suppressed in non-sterilized compost with a maximum population density of less than 10(3) g(-1). There was a significant decline in the growth rate of seeded Salmonella in sterilized compost when the compost was stored, suggesting that bio-available nutrients declined with storage. However, in non-sterilized compost this was not the case. This suggests that the indigenous microflora play a significant role in suppression of Salmonella regrowth in composted biosolids. There was a strong negative correlation (-0.85) between the Salmonella inactivation rate and the maturity of compost in non-sterilized compost. The Salmonella inactivation rate was seven times higher in biosolids composting for two weeks as compared to compost stored for two years. This suggests that the antagonistic effect of indigenous microorganisms towards Salmonella declined with compost storage. It was concluded that all composted biosolids had a Salmonella regrowth potential. However, the indigenous microflora significantly reduced this regrowth potential. Long-term storage of compost is not recommended as this may increase the pathogen regrowth potential.

Methylmercury and the health of indigenous peoples: a risk management challenge for physical and social sciences and for public health policy.

Methylmercury in aquatic ecosystems and bio-accumulated in aquatic biota, especially fish, is a major public health concern internationally. Precautionary efforts are currently underway internationally to reduce the anthropogenic release of mercury, which in turn, over time, will reduce human exposure. However, at the present time, it is important to address the issue of management of the risks of exposure as they exist now. Of particular concern are the impacts of methylmercury on indigenous populations which depend on fish as a subsistence food source, both in remote areas of developed countries, such as Canada, and in developing countries such as Brazil. Research into these impacts over the past two or three decades has shown that, other than in very severe pollution situations such as occurred in Minamata, Japan, the direct impacts on human health are difficult to prove. On the other hand, the indirect negative effects of methylmercury on health, mediated through the disruption of lifestyle and eating patterns and the associated socio-cultural and socio-economic consequences among the affected native populations, have, in many cases, been significant. These social factors have raised serious challenges in determining practical public health policies on the issue. Policy development relating to environmental contaminants has been presented, with the problem of assessing the role of the various factors which contribute to the impact on health as a result of socio-cultural disruption. These factors include changes in diet and lifestyle due to methylmercury in the environment and its real or perceived risk. The standard physical sciences risk assessment process, based on the lowest observed adverse effects level (LOAEL) or no observed adverse effects level (NOAEL) used in defining health policies may be seen as over-simplistic theoretical extrapolations when viewed in the context of the concerns of the social sciences. Both approaches, however, have relevance to health policies that address the risks posed by environmental methylmercury. Therefore, the standard physical sciences approach of the past three decades now needs to be linked with the social sciences approach, with its focus on the indirect impacts of exposure to methylmercury, to provide a comprehensive approach to public health policy development. With this objective in mind, this paper reviews methylmercury-related data from both physical and social sciences. It attempts to draw on the findings in both disciplines to provide suggestions for an integrated approach in policy development relating to human health and human exposure to methylmercury, especially among indigenous peoples in remote areas and in developing countries. An integrated approach such as this may help to limit adverse health effects in the indigenous communities affected.

PCR-based detection of non-indigenous microorganisms in 'pristine' environments.

PCR-based technologies are widely employed for the detection of specific microorganisms, and may be applied to the identification of non-indigenous microorganisms in 'pristine' environments. For 'pristine' environments such as those found on the Antarctic continent, the application of these methods to the assessment of environmental contamination from human activities must be treated with caution. Issues such as the possibility of non-human dispersal of organisms, stability and survival of non-indigenous organisms in vivo, the sensitivity, reproducibility and specificity of the PCR process (and particularly primer design) and the sampling regime employed must all be considered in detail. We conclude that despite these limitations, PCR and related technologies offer enormous scope for assessment of both natural and non-indigenous microbial distributions.

Indigenous first feeding practices in newborn babies.

OBJECTIVE: To describe the common practices in indigenous first feeding of the newborn babies in countries of the continents of Africa, Asia and Latin America. METHODS: Anthropological, medical and nursing publications were searched for indigenous customs and beliefs concerning the first feed given to newborn babies. FINDINGS: From a nutritional point of view the first food is just symbolic but it has a function in either purifying and clearing the 'dirty' throat and bowel or to prepare the baby for adult life. CONCLUSIONS: The general withholding of colostrum should be abandoned and the indigenously strange custom of feeding water with sugar should be discouraged.

Community development through partnership: promoting health in an urban indigenous community in New Zealand.

Indigenous people who have been dispossessed of their lands and resources bear a disproportionate burden of health problems. Programmes aimed at improving their health status must operate within the context of colonisation history and the contemporary cultural renaissance whereby indigenous populations are asserting their rights to self-determination. Community development strategies incorporating empowerment as both means and end are consistent with the aspirations of the renaissance and reflect the principles of the Ottawa Charter for Health Promotion. This paper describes a formative and process evaluation of a community development partnership for health promotion between a health group and an urban Maori community in New Zealand. Key issues encountered related to trust, prioritisation of health, and appropriate research paradigms. Most significant among these was trust, or more specifically, distrust among Maori engendered by historical and contemporaneous experiences of contact with Europeans. Ultimately, the partnership achieved what it set out to do when the Maori partners took over the running of their own health groups and health programme. Building upon a detailed literature review and data from the evaluation, the paper offers a list of recommended procedures for the development of partnerships, applicable to health and other domains. Recommendations encompass preparatory steps, the formation of a partnership committee, programme planning and development, and the appointment of a community-based liaison worker. A conclusion of the research and premise underpinning the recommendations is that devolution of power is a key aspect of organisational process underlying successful partnerships involving professional groups and indigenous people.

Occurrence and diversity of coccidia in indigenous, Saanen and crossbred goats in South Africa.

Occurrence and diversity of Eimeria species in two groups of indigenous South African goats kept under traditional management systems, as well as in a mixed herd of Saanen, indigenous and crossbred goats kept under an intensive management system were examined. Infection rates ranged from 88.7 to 100% in the various groups. Mean OPG of immature goats (< 1 year old) exceeded that of adult goats at all three sites. There was no consistent difference between adult OPG counts at the three sites. Under the intensive system, adult crossbred goats had significantly higher OPG counts than adult Saanen or indigenous goats. Overall, OPG counts of immature goats were significantly higher during the dry season (winter) than during the wet season (summer). Ten Eimeria species were identified, Eimeria arloingi being the most prevalent species at all three sites, followed by Eimeria hirci. Up to seven Eimeria species were recovered from individual specimens.

Nineteenth century Canada: indigenous place of dis-ease.

During the nineteenth century period of intensive European Expansion into Canada, place was experienced with dis-ease by indigenous people. Not only was there less land available for people of the First Nations to live on as in the past centuries, but their intimate relationship with the land was disturbed causing a dis-ease, as their ability to experience place through ceremony was denied. The effects of this process of Euro-Canadian invasion within Canada created a sense of dis-ease, a sense of being out of place for indigenous people. It is my contention that in order to understand health, an awareness of the dynamic connection between a people and their land is needed, recognizing that a quintessential human quality is to imbue the world with meaning in the creation of sense of place. Through examination of a variety of published and unpublished material, archival sources, memos, letters, official documentation, I explore the effects of control of the place of First Nations, on the health and healing practices of the indigenous people.

DNA adducts as indicators of genotoxic exposure in indigenous and transplanted mussels, Mytilus edulis L. from Icelandic coastal sites.

Indigenous mussels, Mytilus edulis, were collected at sites with supposed different amounts of pollution; Reykjavík harbour, Keflavík harbour, Grafarvogur and Hvalfjördur (reference), along the south-western coast of Iceland in March 2000. Mussels from Hvalfjördur and Reykjavík harbour were also collected in August the same year. Additionally, mussels were transplanted from the reference site to Reykjavík harbour for 6 weeks during both winter and summer for comparison. DNA adducts were analysed by 32P-post-labelling in gills and digestive gland. Highest adduct levels were found in gill tissue from indigenous mussels collected in Reykjavík harbour. Adduct levels in both tissues from mussels collected at the reference site were below or very close to the detection limit during winter, but seemed to increase a little during summer. Mussels from sites with supposed intermediate pollution had intermediate levels of DNA adducts in gills but did not differ from Reykjavík harbour in digestive gland. No increase in adduct levels was observed in mussels transplanted from the reference site to Reykjavík harbour, except for a slight increase in digestive gland during winter. This study shows that 32P-post-labelling analysis of DNA adducts is sensitive enough to be used on indigenous mussels from relatively pristine areas and that adduct levels are increased in harbours/urban sites. However, transplantation of mussels from a clean site to the harbour for 6 weeks did not result in increased adduct levels in gills, the tissue with the highest adduct levels. The results also indicate that seasonal variation in adduct levels may occur.

Methyl tert-butyl ether biodegradation by indigenous aquifer microorganisms under natural and artificial oxic conditions.

Microbial communities indigenous to a shallow groundwater system near Beaufort, SC, degraded milligram per liter concentrations of methyl tert-butyl ether (MTBE) under natural and artificial oxic conditions. Significant MTBE biodegradation was observed where anoxic, MTBE-contaminated groundwater discharged to a concrete-lined ditch. In the anoxic groundwater adjacent to the ditch, concentrations of MTBE were > 1 mg/L. Where groundwater discharge occurs, dissolved oxygen (DO) concentrations beneath the ditch exceeded 1.0 mg/Lto a depth of 1.5 m, and MTBE concentrations decreased to <1 microg/L prior to discharge. MTBE mass flux calculations indicate that 96% of MTBE mass loss occurs in the relatively small oxic zone prior to discharge. Samples of a natural microbial biofilm present in the oxic zone beneath the ditch completely degraded [U-14C]MTBE to [14C]CO2 in laboratory liquid culture studies, with no accumulation of intermediate compounds. Upgradient of the ditch in the anoxic, MTBE- and BTEX-contaminated aquifer, addition of a soluble oxygen release compound resulted in oxic conditions and rapid MTBE biodegradation by indigenous microorganisms. In an observation well located closest to the oxygen addition area, DO concentrations increased from 0.4 to 12 mg/L in <60 days and MTBE concentrations decreased from 20 to 3 mg/L. In the same time period at a downgradient observation well, DO increased from <0.2 to 2 mg/L and MTBE concentrations decreased from 30 to <5 mg/L. These results indicate that microorganisms indigenous to the groundwater system at this site can degrade milligram per liter concentrations of MTBE under natural and artificial oxic conditions.

Phenotypic characterization of indigenous Tswana goats and sheep breeds in Botswana: continuous traits.

The majority of Tswana sheep and goats in Botswana are indigenous. These animals provide income, employment and food security to the resource-poor farmers. Limited characterization of these species has been done, resulting in poor efforts to fully exploit and conserve them. The objective of this study was to phenotyically characterize indigenous sheep and goats countrywide. Measurements were collected from 2783 goats and 1282 sheep kept by traditional farmers, covering nearly all the districts of Botswana. In each district a total of 15 farmers with sheep and goats were selected randomly and records were taken on 4-12 animals per farm, depending on average district flock size. Traits recorded for each animal were body length, body weight, ear length, heart girth, height at withers, hip width, neck length, rump height, shoulder width, tail length (goats only) and horn length. Age (estimated from dentition) and sex of the animals were also recorded and vegetation type was noted. The data were analysed using the general linear model procedure in Statistical Analysis System. Prior to analyses, a main effects model of sex, age and vegetation type was fitted. Later, two types of analyses were done: (i) within a vegetation type fitting sex and age and their interaction, and (ii) within sex fitting age and vegetation type and their interaction. Least-squares means were separated using Student's t-test. Sex, age and vegetation significantly (p<0.05) affected the magnitude of traits. Phenotypic body measurements of castrates were generally higher than in both females and entire males, which were similar. The body measurements of younger animals were less than those of older age groups since the former were still growing compared to the latter. Different vegetation types promoted different body measurements, which should be expected due to differences in nutrient supply from different vegetation types. The indigenous breeds of sheep and goats can be classified as medium-size breeds. The breeds should be conserved since they are well suited to the harsh environment of Botswana where drought and livestock diseases are ever present. Efforts should be undertaken to characterize them genetically and increase their productivity.
