Regeneration potential of selected medicinal plants used to treat human and livestock diseases in Limpopo Province of South AfricaOjelade, Babatube Solomon 16 May 2018 (has links)
MSCAGR ( Plant Production) / Many high valued tree species of medicinal significance in the Limpopo Province,
South Africa exhibit seed dormancy, and also contain aromatic oils which inhibit
rooting of their stem cuttings. These plant species are under pressure due to human
over-exploitation. The main objective of this study was to investigate effects of
rooting hormones on the rooting ability that will help in domesticating some of the
selected high valued medicinal plants, Elaeodendron transvaalense (bushveld
saffron), Brackenridgea zanguebarica (yellow peeling plane), and Warburgia
salutaris (pepper-bark tree). Stem cuttings of these plant species were prepared and
treated with various concentrations (500, 1000 and 2000 ppm) of IBA, IAA and NAA
in different growth media (Natural soil, farm soil and hygromix) at a nursery house.
180 experimental units were sown and arranged in Randomized Complete Block
Design (RCBD), each treatment replicated five times and then monitored for a period
of three months. Data were only obtained from Brackenridgea zanguebarica as other
species dried up two weeks after sprouting. The two variables measured from the
experiments were sprouted stems and number of leaves. The data obtained were
subjected to analysis of variance and least significant difference (LSD) at 5%
probability level was used to compare treatment using STATISTICA software
analysis package. The hormone, hormone concentration, growth media and their
interactions had effect on sprouted stems and number of leaves produced on
Brackenridgea zanguebarica cuttings, with no record of rooting ability. IBA (500 ppm
and 1000 ppm) and control (without rooting hormone) showed high significant results
with natural soil and farm soil in terms of leaf production compared to the hygromix,
which is significantly lower from others. IBA at the various concentrations (500, 1000
and 2000 ppm) and the control gave the highest percentage sprouted stem on both
natural soil and farm soil as compared with other hormones at the same / NRF

Traditional healing modalities in the provision of mental illness in Vhembe, Limpopo ProvinceNevhudoli, Nyadzani Dolphus 18 May 2018 (has links)
MAAS / Centre for African Studies / The study sought to explore the use of traditional healing modalities in the provision of mental illness in the Vhembe district of Limpopo province. Traditional medicine has been used for thousands of years by indigenous people in South Africa and Africa as a whole, and demonstrated efficacy in treating a wide range of health issue. Many of the medicines in contemporary biomedical treatment are derived from plants and herbs used by indigenous people throughout the world. The objectives of the study were to describe the profile of the clients that visit the traditional healers, to explain traditional healers’ diagnostic strategies of mental illness, to explain the traditional healing treatment modalities in the treatment of various forms of mental illness and to discuss traditional healers’ prevention methods of mental illness. The study was guided by indigenous theory of health and illness as a theoretical framework, and for supporting the literature, a theory of African perspective theory was used. A qualitative research approach was used in order to have an in-depth understanding of the modalities of traditional healing in the provision of mental health care. Case study approach was used. Participants were selected purposively around Vhembe district in Limpopo province and snowball sampling technique was applied in order to identify and recruit relevant participants. The researcher conducted semi -structured interviews to gather the relevant data. Data analysis was based on the interpretative philosophy that aimed at examining meaning and symbolic content of qualitative data. Thematic analysis method was employed. The findings of the study confirmed that traditional healing is still widely used in the communities in the provision of mental illness and that there are a variety of diagnostic, treatment and prevention methods in the provision of mental illness. The findings also show that as much as there are challenges facing traditional healing in treatment of mental illness, there is a need to introduce their modalities in the healthcare system of South Africa, Africa and the whole world. Programs that aim to educate the communities about traditional healing modalities should also be established by the Department of Health and the relevant stakeholders such as traditional healers’ organizations. / NRF

Synthesis, Characterization and Evaluation of Novel Treatment against Resistant Pathogenic BacteriaMurei, Arinao 18 May 2019 (has links)
MSc (Microbiology) / Department of Microbiology / BACKGROUND: Antibiotic resistance amongst microbial pathogens has become a challenge over past decades, bringing about genuine and frequently deadly contaminations that can't be dealt with by ordinary means. This has led to a search on developing solutions to this problem by searching for new source of antimicrobial agents or chemically altering the existing ones. Traditional medicinal plants and nanoparticles are highly targeted as promising agents to address the challenge. Pyrenacantha grandiflora Baill from Icacenaceae family possess pharmaceutical activities and is used by Vhavenda people to cure gastrointestinal related infections, diarrhea and tooth pain.
OBJECTIVES: The present study aimed to synthesize, characterize and evaluate the efficacy of Pyranacantha grandiflora extracts alone and when conjugated with selected nanoparticles against pathogenic microorganisms. Furthermore, this study investigated the efficacy of selected antibiotics when conjugated with nanoparticles against selected pathogenic microbes.
METHODS: Pyrenacantha grandiflora Baill (tubers) were collected from Masisi area. Bioactive compounds were extracted using different solvents such as methanol, acetone, hot water, dichloromethane and chloroform. Preliminary phytochemical screening was done to identify different phytochemicals in the extracts and their functional groups were identified by Fourier Transform Infrared spectroscopy (FTIR). Extracts were further assessed for their total phenolic and flavonoids content. Thin layer chromatography was used to separate the compounds from the plant extracts and active compounds/group of compounds were identified by bioautography. The antioxidant ability of the extracts to scavenge free radical DPPH was also determined. Silver and gold nanoparticles were synthesized using chemical and biological methods, characterized by Ultraviolet-Visible Spectrophotometry (UV-VIS), Transmission Electron Microscopy (TEM) and Energy dispersive X-ray analysis (EDX). Plant extracts, nanoparticles and antibiotics were
xix
conjugated differently, and conjugates were analyzed by FTIR and their antimicrobial activities were evaluated against different bacteria and fungi. The conjugates were tested for antimicrobial activity against extended beta-lactamase producing Escherichia coli (ATCC 35218), Escherichia coli (ATCC 25922), methicillin-resistant Staphylococcus aureus (ATCC 25923), methicillin-susceptible Staphylococcus aureus (ATCC 33591) and beta-lactamase producing Klebsiella pneumonia (ATCC 700603) using agar diffusion assay and the minimum inhibitory concentrations (MIC) were determined using the microdilution method. The minimum bactericidal concentration (MBC) and minimum fungicidal concentration (MFC) were determined by sub-culturing from the MIC plates on Mueller-Hinton Agar.
RESULTS: Pyrenacantha grandiflora was found to contain phenolics, saponins, alkaloids, tannin, steroids, terpenoids and flavonoids. FTIR spectroscopic studies revealed different characteristic peak values with various functional compounds similar in most extracts but differed with transmittance values. The total phenolic contents in the examined extracts ranged from 14.167 to 19.02 mg GA/g. The total flavonoid content in the examined extracts ranged from 26.603 to 34.621 mg QE/g. Thin-layer chromatography revealed various Rf values and when analyzed with bioautography, well-defined inhibition zones within the Rf value of 0.236 was identified against E. coli and K. pneumonia. The MICs of the extracts were determined, and all the extracts showed some antimicrobial activity against all tested strains ranging from 0.06-7.5 mg ml/g. Some extracts appeared to be fungicidal and hot water extracts were more active against Cryptococcus neoformans with the MFC value of 0.06 mg/ml. The methanol extract was also active against most tested strains including Candida tropicalis with the minimum fungicidal concentration value of 3.75 mg/ml. Pyrenacantha grandiflora tuber extracts conjugated with silver or gold nanoparticles exhibited a good antibacterial activity against all bacterial strain used and very few were able to exhibit bactericidal activity. Penicillin showed improvement of antibacterial activity
xx
when conjugated with compounds from the acetone extracts and vancomycin was found to be more effective when conjugated with silver nanoparticles and water extracts.
CONCLUSION: The present study validated the efficacy of conjugated P. grandiflora tuber extracts which is used in traditional medicine. The results revealed that water extracts which are generally used by the traditional healers are active against most microorganisms tested as well as methanol and acetone extracts and the synergistic effect was observed when they were conjugated to gold and silver nanoparticles. The results of the present investigation clearly indicate that antimicrobial activity of Pyrenacantha grandiflora Baill tuber when conjugated with selected nanoparticles and antibiotics vary with test strain and the type of solvent used during extraction, thus giving hope for future development of drug leads. / NRF

Poverty, health and disease in the era of high apartheid: South Africa, 1948-1976Phatlane, Stephens Ntsoakae 30 November 2006 (has links)
A higher infant mortality rate and shorter life expectancy, coupled with a high prevalence of a variety of diseases commonly associated with malnutrition, are usually a reflection of the social conditions of poverty in a society. By arguing that apartheid formed the basis of inequality and therefore the main underlying cause of an unacceptable burden of the diseases of poverty among black South Africans, this thesis, Poverty, Health and Disease in the Era of High Apartheid: South Africa, 1948-1976, locates these health problems within their social, economic and political context. It further argues that if health and disease are measures of the effectiveness with which human beings, using the available biological and cultural resources, adapt to their environment, then this relationship underpins the convergence of medical and cultural interests. Under the impact of modern technology and society's dependence upon it, profound cultural changes have taken place and issues of health and the etiology of disease are among the areas most affected by these changes. This thesis explains why, in a pluralistic medical setting, where only modern (scientific) medicine was recognised as legitimate medicine by the apartheid government, for the majority of black South Africans the advent of modern medicine was viewed not so much as displacing indigenous (African) medicine but as increasing the medical options available to them. It is therefore contended here that for most black South Africans, indigenous medicine has played a critical role; it has mitigated the impact of apartheid medicine. Since differences that people perceive in these two medical systems are crucial to the medical choices that they make at the onset of illness, this thesis argues that knowing and understanding the reasons for making such choices would not only have practical value for health authorities in their efforts to improve local, regional and national health service delivery, but would also contribute to a general understanding of human therapy-seeking behaviour in this age of the HIV/AIDS pandemic. / History / Thesis (D.

Use of the Athrixia phylicoides plant in Tshwane: an anthropological studySiko, Maggie Ngwanamaphoto 02 1900 (has links)
This study focuses on the use of the Athrixia phylicoides plant in Tshwane, Gauteng, South Africa. The plant is used within the domestic domain as a beverage, for medicinal purposes, as well as for the manufacturing of domestic brooms. The aim of the study was to investigate the use and market of Athrixia phylicoides in two of the Tshwane markets, namely; Denneboom and Marabastad. Case study design, participant observation and interviews were employed to collect data. A literature review was conducted to construct a theoretical framework. The study reveals that traditional healers, broom makers and customers have a remarkable knowledge about Athrixia phylicoides, which has been untapped thus far. In addition, the study indicates that possible extinction of the Athrixia phylicoides plant, due to over-harvesting and lack of conservation, will pose a challenge to the market. / Anthropology / M.A. (Anthropology)

A practical theological study of the efficacy of the Roman Catholic Church, Witbank Diocese’s teaching regarding the healing ministry : towards the development of an integrated and intercultural healing ministryMagagula, Vusumuzi Jan 11 1900 (has links)
Sickness is a problem that has not escaped any society and thus is on the agenda of every culture. Since time immemorial cultures have searched for answers to the questions raised by the phenomenon of sickness but none have provided solutions, as it has become clear that sickness is part of our human existence. Many people have resorted to religion in search consolation in times of affliction and the Roman Catholic Church is not immune to this expectation, as we see many leaving the church in search of healing in the African Traditional Religions and other Christian churches because they feel that the church is inadequately dealing with the problem. In this study the author undertakes a research journey within the Diocese of Witbank of the RCC to investigate as to why the church’s healing ministry is not effective. Through engagement with participants in the research field and relevant literature the author discovered that the RCC is seen to be suspicious of the African worldview and consequently does not take its members’ fears and frustrations around the phenomenon of sickness serious as it judges them to be superstitious. This suggests that there is nothing that Western Christianity can learn from African cultures maintaining its superior attitude and further alienating indigenous communities. The author suggests that in order for the RCC to responds with relevance to this problem it needs to reconcile the Christian worldview, which is western, with the African worldview. He puts high on the agenda of Christian theology the urgent call to African theologians to develop an African theology that will give birth to a genuine African Christianity. In conclusion as a solution the author proposes an integrated and intercultural healing ministry for the Diocese of Witbank. This model is aimed at appropriating African values, idioms and language in the RCC to create an atmosphere where the church is seen as a welcome guest who comes bearing gifts but at the same time expects to be taken care of by its host. / Philosophy, Practical and Systematic Theology / M. Th. (Pastoral Therapy)
