dc.descriptionThesis (MTech (Biomedical Technology))--Cape Peninsula University of Technology, 2015.
dc.description.abstractDiabetes mellitus (DM) is an endocrine disorder that is characterised not only by severe hyperglycemia but also altered metabolism of glucose and lipids. It is a major health problem worldwide and its impact is greatly noticed in developing countries due to the lack of adequate medical facilities. Oxidative stress remains the principal factor that actively plays major roles in the onset and progression of diabetes mellitus and its complications. The use of medicinal plants in the treatment of DM has undisputedly gained the attention and interest of researchers throughout the globe mainly because plants have established promising outcomes in the treatment of diabetes. It is evident that the plants’ constituents possess therapeutically potent metabolites that have beneficial effects such as antioxidant, antidiabetic, anticancer, anti-inflammatory and antibacterial activities. Hypoxis hemerocallidea is a native plant that grows in the Southern African regions. H. hemerocallidea is well known for its beneficial medicinal values. In South Africa it is known as the African potato. The main aim of this study was to investigate both the beneficial and also the possible toxic effects of H. hemerocallidea in the kidney and liver tissues of streptozotocin-induced diabetic male Wistar rats by assessing the antioxidant status and selected biochemical parameters in the two studied organs. Diabetes was induced in overnight fasted rats by administration of a single intraperitoneal injection of STZ at a dosage of 50mg/kg in citrate buffer (0.1 M at 4.5 pH). Hyperglycemia was confirmed 72 hours after induction of diabetes using STZ in rats with glucose levels > 15 mmol/l. Treatment with the plants extract commenced on the fourth day after STZ administration via gastric gavage that was done once a day over a 6 week period. The effects of H. hemerocallidea on glucose, body weight, liver and kidney weights, liver function, kidney function and the oxidative status were evaluated after the feeding period.
