This study sought to ascertain the role that is played by traditional healers in healthcare delivery among the Nguni people of South Africa. Its objective is to ascertain who the traditional healers are, how they are trained for the profession, how they practice their profession including how people consult with them, how they gather information relevant to identify the problems of their clients, what interventions are put in place once health problems have are identified and generally the role traditional healers play in the wellbeing and upliftment of living conditions of their communities. Three traditional healers were interviewed and observed, generating important information for the study. The study found out that traditional healers are respected traditional or community leaders whose main contribution to the community is practicing healthcare delivery by which they bring well-being to the generality of the people. Traditional healers are called to their profession by their ancestors. The training of traditional healers is by apprenticeship with experienced renowned traditional healers and the training takes place between two and six years. Training takes place in the skills of diagnosis or the gathering of information, through observation, interviews, divination and the interpretation of dreams to arrive at a decision as to the probable healthcare needs or health problems of patients. Traditional healers are generally trained to be capable of identifying different kinds of problems affecting people, whether these be physical, mental or interpersonal relationship problems. Training in skills to intervene in health matters are provided including herbal medication, interpersonal interactions and as in group healing or ritual ceremonies as well as training in the skills of prevention of ill-health and promotion of health. Other skills in which traditional healers are trained include those of advocacy, mobilization and being custodians of the people's traditional culture. Traditional healers are generally trusted for their competency and the efficacy of their intervention strategies and this explains the reason for the people's generally positive behaviour tendency towards the utilization of traditional healer's services. Traditional healers generally bring about well- being to the people in their communities. / Thesis (M.Ed.) - University of KwaZulu-Natal, 2007.

Aflatoxin B1 (AFB1), a potent hepatotoxic and hepatocarcinogenic mycotoxin synthesised by toxigenic fungi (Aspergillus flavus and Aspergillus parasiticus), is a common contaminant of many cereal commodities consequently posing a major threat to human and animal health. Sutherlandia frutescens (SF), a traditional medicinal plant endemic to Southern Africa, is commonly used by many cultures as a tonic for various health-related conditions. Incidentally, the present study aimed at investigating the potential hepatoprotective capacity of SF and L-canavanine (L-can, a major constituent of SF) against AFB1-induced cytotoxicity in human HepG2 cells and used a standard treatment procedure of 24 h. Cell viability was evaluated using the methyl thiazol tetrazolium (MIT) assay, which effectively demonstrated the ability of SF, when administered individually and in combination with AFB1, to be significantly cytotoxic to HepG2 cells in a dose-dependant manner. Reactive oxygen species (ROS) and consequent peroxidative damage caused by AFB1 are considered to be the main mechanisms leading to hepatotoxicity and was confirmed by the thiobarbituric acid reactive substances (TBARS) assay which revealed that AFB1 mediated a significant increase in lipid peroxidation. Additionally, comet assay analysis demonstrated the most pronounced effect to be observed following administration of AFB1. In contrast, AFB1-mediated genotoxicity was significantly reduced by SF and L-can. Such amelioration can be attributed to the marked increases in glutathione (OSH) levels observed after the co-administration of SF and L-can with AFB1. Cytoprotection by SF and L-can against AFB1-induced toxicity was further substantiated by the significant increases in heat shock protein 70 expression. Moreover, when SF and L-can were co-administered along with AFB1, analysis by flow cytometry revealed that AFB1 induced increases in apoptosis and necrosis were reduced. The findings of this study propose that SF and L-can may be selectively effective in alleviating AFB1-induced cytotoxicity and lends pharmacological credibility to the suggested ethnomedical uses of SF. However, the exact mechanism of action and the extracts efficacy in humans requires further authentication. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2008.

The world today faces many challenges. Reducing poverty and protecting the environment are prominent amongst these challenges, and consequently both are high on priority lists for many national, international, governmental and non-governmental organizations. Since the 1980s there has been an increasing awareness that environmental protection must not fly in the face of social justice, especially in developing countries, and that a system can only truly achieve sustainability if it is socially just and economically sound, as well as environmentally secure. Likewise poverty reduction at the cost of the environment is worthless in the long term. This has given rise to much more holistic approaches to both conservation and poverty reduction policies and brought the rights of communities living in or near protected areas into the international focus. However, wether it is possible to conserve biodiversity and protect habitats successfully without undermining the livelihoods of local communities, or wether it is possible to offer development aid to an impoverished region without jeopardizing their local environment, is a question which has not been resolved. This study approaches this debate by examining the relationship between the livelihoods and natural resources of a rural village adjacent to a forest reserve on the Mambilla Highlands in Nigeria. A mixture of qualitative and quantitative techniques were employed during five months spent living on location to develop a picture of the situation as it currently exists, the environmental effects of development in the village to date, and the effects of these environmental changes on people’s livelihoods. Based on this research this thesis concludes that development in a region certainly increases the vulnerability of the environment. However, rather than concluding that this makes development and environmental protection conflicting agendas, this thesis argues that this period of vulnerability presents opportunities to develop true sustainability, as effective sustainable practices can develop from the experience of resource depletion. Additionally, examples of how knowledge sharing and dialogue between western scientists and indigenous communities has the potential to facilitate and accelerate this process are discussed.
