M.Tech. / Allergic rhinitis is on the increase around the world affecting between 15-20% of the global population and is the most common chronic condition of children in South Africa. Luffeel® is a propriety complex homeopathic product manufactured by Biologische Heilmittel Heel. It is available in nasal spray and tablet form. These two forms are designed to work in combination with each other in the treatment of allergic rhinitis. The aim of this study is to determine the effect of a combination of Luffeel® nasal spray and Luffeel® tablets on allergic rhinitis using Phadiatop® tests, RAST Inhalant screens and subjective evaluation on symptoms such as nasal itching, sneezing, congestion, discharge, ocular redness and itching as indicators. This study was a double-blind, placebo-controlled study conducted at the University of Johannesburg, Doornfontein campus over a period of eight weeks. Thirty participants were recruited by poster advertisement. It can be concluded that Luffeel® nasal spray and Luffeel® tablets decrease the symptoms of allergic rhinitis, when compared to the placebo, thus giving persons suffering from allergic rhinitis an alternative treatment with no rebound or lethargic effects. It can also be concluded that this study that Luffeel® nasal spray and Luffeel® tablets has no significant effect on Phadiatop® and RAST inhalant screens over an eight week period. The results are inconclusive due to the small sample size and short time frame of the study.

M.Tech. (Homoeopathy) / Insulin resistance is defined as the impaired ability of plasma insulin to facilitate peripheral glucose disposal, suppress hepatic gluconeogenesis and inhibit very low density lipoprotein (VLDL) output (Caceres et al., 2008). Insulin resistance is not a disease, but rather a feature and attribute of the Metabolic Syndrome, which is associated with a high risk of developing type two diabetes mellitus and cardiovascular disease (Brewer, 2005). Insulin resistance (IR) is globally regarded as the common and fundamental aetiological factor of the various components of the Metabolic Syndrome namely abdominal obesity, dyslipidaemia, insulin resistance and hypertension (Zimmet, 1991; Haffner et al., 1992 Stern, 1997; Beck Nielson & Groop, 1994; Tsai et al., 2012). Diabetes mellitus type 2 is a rapidly growing worldwide epidemic, but only diagnosed once the underlying metabolic abnormalities have caused damage. The fact that many recently diagnosed diabetic patients already suffer from so called “late complications of diabetes” indicates that the pre-diabetic condition is harmful to health and needs to be addressed promptly to slow down or avoid the progression to diabetes mellitus type 2 (Beck Nielson & Groop, 1994; Brewer, 2005; Tsai et al., 2012). Treatment of insulin resistance proves very difficult as dietary and lifestyle choices play an integral role in the development, treatment and management of insulin resistance; and insulin resistant patients also seem resistant to changing their behaviour (Brewer, 2005). Current conventional treatment options are limited in efficacy and may be associated with significant side-effects (Brewer, 2005; Snyman, 2009; Neal, 2003), while coherent studies on combination complementary forms of treatment are lacking (Chen et al., 2003; Guan et al., 2000; Hull, 2008; Verma et al., 1998; Winston & Kuhn, 2007; Ye et al., 2001). This study aimed to determine the efficacy of the herbal and nutritional formulation Glucostate™ in FoodState® form, on the HOMA index of insulin resistant patients. This was a collaborative randomized double-blind and double-dummy placebo controlled quantitative research study that included 40 participants. Due to the inherent nature of associated race, age and gender bias, participants were matched according to these criteria and randomly allocated to either an experimental or control group (Appendix C). The placebo group was shared between two collaborative studies. Participants volunteered to participate in the study, were between the ages of 20-45 years and consented to the procedures of the study. Participants in the treatment group received Glucostate™ tablets and placebo drops and the participants in the placebo group received placebo tablets and placebo drops. The research study was conducted over a period of 16 weeks per participant at the University of Johannesburg Health Training Centre, Doornfontein Campus. Participants were asked to maintain their original lifestyle and diet and continue as is normal for them, as alterations in weight have an effect on insulin levels. Participants were screened using blood pressure, abdominal girth, height, weight and Body Mass Index (BMI); these measurements were repeated at weeks 4, 8, 12 and 16. Fasting blood tests consisting of a lipogram, fasting glucose and fasting insulin level were done prior to and at the conclusion of the study. The Homeostasis Model Assessment (HOMA) index was calculated from the fasting insulin and glucose values. Results acquired from the research study were statistically analyzed by Statkon at the University of Johannesburg by means of descriptive statistics, parametric and non-parametric tests. The only parameters which showed statistically significant improvement for the Glucostate™ group and not the placebo group were systolic blood pressure (SBP) (p=0.004) and diastolic blood pressure (DBP) (p=0.050). There was no statistically significant change in any of the other parameters when compared to placebo. This research study determined that Glucostate™ was not effective in reducing insulin resistance and the parameters directly associated with its measurement especially when compared to the effects of placebo.

M.Tech. / Obesity is a serious health problem throughout the world, with the number of cases having increased three-fold over the last two decades, reaching epidemic levels in the United States (Kumar and Clark, 2009). According to the South African Demographic and Health Survey (SADHS) of 2002, 29.2% of South African men were overweight, whereas 56.6% of women were overweight. Obesity leads to a decreased quality of life and can have a detrimental effect on general well being (SADHS, 2002). Overweight and obesity have major psychological effects on the individual. Obese individuals often suffer from body image issues, unhappiness, a decreased morale, low self esteem and eating disorders (Rogge et al., 2004). The stigma associated with adolescent obesity causes bullying in school as well as childhood psychiatric morbidity (Gortmaker et al., 1993). The aim of this study was to determine the effect of an herbal formulation consisting of Coleus Forskohlii, Camellia sinensis, Coffea canephora, Caffeine, Evodiamine, Ilex paraguariensis and Phaseolus vulgaris on general well being in overweight and obese individuals. This study was a quantitative double-blind, placebo-controlled study, using matched pairs according to gender and body mass index (BMI). The study was conducted over twelve weeks during the period of October 2011 to January 2012 at the University of Johannesburg’s Homeopathy Clinic. The conducted study formed part of a larger study where the research sample was shared by two additional researchers (Durrheim et al., 2012) (Withers et al., 2012). This allowed for a larger sample group to be tested with numerous variables being researched. The study included sixty overweight and obese males and females between the ages of eighteen and forty five, with a BMI above 25 kg/m² and under 35kg/m². Participants were required to sign a Participant Information and Consent form (Appendix B) giving the necessary information regarding this study. The groups were randomly matched assigned by the dispenser (according to the participant’s BMI) to the experimental group or placebo group, each consisting of thirty participants. The medication was randomised by the homeopathic dispenser at the University of Johannesburg’s Homeopathy Clinic. The experimental group received a bottle of capsules containing the herbal formulation, and the placebo received identical looking placebo capsules containing a pharmaceutical maize starch.

Resistance of human pathogenic bacterial strains results in selective pressure against known antibiotic. However, plant derived compounds that possess antibacterial potential are currently being investigated for treatment of wound infections in diabetic patients as they are inexpensive and non-toxic. Hence, this dissertation was designed to evaluate two medicinal plants (Brachylaena elliptica and Brachylaena ilicifolia) traditionally used in the treatment of various diseases such as diabetes, and its secondary complications in diabetic patients. The in vitro antioxidant activity of both plants were evaluated using DPPH (1, 1-diphenylhydrazl), ferric reducing power, ABTS (2, 2’-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid), NO (nitric oxide) and H2O2 (hydrogen peroxide) techniques. The antibacterial test and Minimum inhibitory concentration (MIC) was determined by agar dilution method against 5 bacteria strains (Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pyogene, Proteus vulgaris and Proteus mirabilis) infecting wounds in diabetic patients using amoxicillin and ciprofloxacin as positive control. The phytochemical analyses were assessed using standard published methods. Identification of bioactive components in essential oils of both plants were assessed using GCMS. The aqueous and ethanol extracts of both plants were also evaluated to identify bioactive components using LC-MS. The results of the phytochemical analysis revealed the presence of phenols, tannins, flavanoids, flavanols, proanthocyanidins, saponins and alkaloids in both plants. Both plants indicated strong antioxidant activities which might be due to the presence of bioactive compounds. The aqueous and ethanol leaf extracts of both plants demonstrated appreciable broad spectrum activities against these wound pathogens with MIC ranging between 5 and 0.3 mg/ml. The GC-MS analysis of the essential oils of both plants revealed the presence of monoterpenes, oxygenated sesquiterpenes, phenolics and esters. The LC-MS analysis of the aqueous and ethanol leaf extracts of both plants showed that both plants are rich in alkaloids, terpenes, terpenoids, monoterpernoids, and flavanoids. Conclusively, this study has partially justified the ethnomedicinal use of B. elliptica and B.licifolia leaves for the treatment of various diseases, including diabetes and wound infections caused by bacteria in diabetic patients. These may be attributed to the presence of antioxidant compound such as phenols, flavanoids, saponins, tannins, alkaloids and other phytochemical compounds.
