Submitted in partial compliance with the requirements of the Master’s Degree in Technology: Homoeopathy, Durban University of Technology, Durban, South Africa, 2016, / Background Diabetes mellitus is a metabolic disorder with various aetiologies, characterised by hyperglycaemia, resulting from defects of carbohydrate, fat and protein metabolism due to the deficient action of insulin on target tissues caused by insensitivity to or lack of insulin or both. The long term effects of diabetes mellitus frequently include retinopathy, nephropathy and neuropathy and an increased risk of other diseases such as cardiac, peripheral arterial and cerebrovascular disease. According to the International Diabetes Federation (IDF) 387 million people have diabetes mellitus and this number is predicted to rise to 592 million worldwide by 2035. In 2014 diabetes mellitus caused 4.9 million deaths worldwide and every 7 seconds a person dies from diabetes mellitus. The growing incidence of diabetes mellitus is a worldwide concern because of the increase of economic costs and burden of disease that is due to the cardiovascular complications and the co-morbidities. Objective The aim of this double-blind, randomised clinical trial was to determine the efficacy of Syzygium jambolanum (Java plum) 6CH and Syzygium jambolanum (Java plum) homoeopathic mother tincture on daily fasting blood glucose and glycosylated haemoglobin levels in type 2 diabetes mellitus patients on Metformin® in the treatment of type 2 diabetes mellitus. Material and Method A sample consisted of 24 volunteers selected on the basis of inclusion and exclusion criteria. These participants were then randomly divided into two groups, 13 in the group receiving the homoeopathic potency and 11 in the group receiving the homoeopathic mother tincture. Each participant attended a total of five consultations with the researcher over a period of 14 weeks that included a 2 week baseline period followed by a 12 week treatment period, at the Durban University of Technology (DUT) or Kenneth Gardens Homoeopathic Day Clinic. At each consultation a detailed and comprehensive homoeopathic case history (Appendix D) was taken and a physical examination (Appendix E) was performed by the researcher. Participants were required to fill in a log sheet (Appendix C1 and C2) with their fasting blood glucose readings daily for 14 weeks, which included a 2 week baseline period followed by a 12 week treatment period. Participants were also required to have their glycosylated haemoglobin measurements tested pre- and post-treatment. Results Both groups reflected a statistically significant reduction in fasting blood glucose levels as compared to the baseline. The mean fasting blood glucose level in week 1 was 11.8802 whereas in week 13 the mean blood glucose level was 8.6590 with a p value ≤ 0.05 for the Syzygium jambolanum 6CH group and the mean blood glucose level in week 1 was 9.0338 with a standard whereas in week 13 the mean blood glucose level was 6.8591 with a p value ≤ 0.05 in the Syzygium jambolanum homoeopathic mother tincture. However there was no significant differences between the two groups (Syzygium jambolanum 6CH and Syzygium jambolanum homoeopathic mother tincture), the significance score was 0.623 when comparing reduction in fasting blood glucose levels. Both groups reflected a statistically non-significant reduction in the glycosylated haemoglobin (HbA1C) and there were no significant differences between the two groups when comparing reduction in HbA1C levels. Conclusion Both homoeopathic preparations of Syzygium jambolanum (mother tincture and 6CH) significantly reduce fasting blood glucose levels in patients with type 2 diabetes mellitus. This result suggests that Syzygium jambolanum has beneficial anti-diabetic effects and warrants further investigation. / M

Diabetes has alarming prevalence rates not only in the U.S., but also worldwide. Ethnicity plays a large role with Hispanic-Americans having one of the highest prevalence rates. Diabetes is a complicated disease that requires significant lifestyle modifications. The health belief model (HBM) has been investigated as a theory to explain behavior change. However, little research has been done to determine its utility to Mexican-Americans. In the current study, participants were Mexican-American adults (N = 66) with type II diabetes who were recruited from family medicine clinics. Self-report questionnaires included the General Acculturation Index (GAI) and the Multidimensional Diabetes Questionnaire (MDQ). Participants had the option to complete them in either Spanish or English. Laboratory values were collected from medical charts. A MANCOVA indicated that two variables were significant, perceived severity (PS) and misguided support behaviors (MSB), p < .05. With respect to the HBM, PS was identified as a component of an individual's perception, acculturation was a modifying factor, and MSB was a component of the likelihood to change factors. These three affected glycemic control. Odds ratios determined that individuals with better glycemic control had less perceived severity and less misguided supportive behavior. Individuals with the least acculturation were more likely to have best glycemic control. Significant results were found for each of the three main columns of the model suggesting that the HBM has utility for the Hispanic-American population with type II diabetes. Results suggest that health care personnel should be aware of the ramifications of patients' perceived severity of their illness as well as the amount the "nagging" type support they receive from friends and family on glycemic control. This awareness can lead to the development of interventions aimed at improving glycemic control and the quality of life in Mexican-Americans with diabetes. Specifically, programs focused on incorporating the family may lead to improved psychosocial and educational outcomes since familial relationships are crucial in this population.

Este trabalho teve como objetivo conhecer como se dão as interações familiares de adolescentes com diabetes tipo 1 desde o diagnóstico da doença.Utilizou-se como referencial metodológico a História Oral .Os dados coletados mediante entrevistas gravadas com sete adolescentes foram analisados à luz do Modelo Calgary para Avaliação da Família de Wright e Leahey.As narrativas demonstraram que apesar do acréscimo de atividades na rotina diária do adolescente e da família, relacionadas à manutenção e controle do diabetes, as interações familiares sofrem poucas modificações com a chegada da doença e que os conflitos entre os pais e o adolescente com diabetes não diferem tanto daqueles ocorridos entre os pais e adolescentes saudáveis.A superproteção foi um sentimento percebido pelos adolescentes após o surgimento da doença,pois os pais têm preocupações com complicações imediatas e em longo prazo. O principal vínculo demonstrado pelos adolescentes entrevistados com a suas famílias foi o vínculo de confiança. Para eles é muito importante saber que conquistaram a confiança de seus pais de que podem ter certa autonomia em relação ao manejo do diabetes.Com os irmãos compartilham superficialmente o diabetes,mesmo aqueles que mantêm relações mais estreitas.A família extensa também oferece contribuições em diferentes fases da doença. Os adolescentes entrevistados forneceram dados de que sua comunicação verbal com sua família é ampla e direta. Sentem-se livres e confiantes em falar abertamente sobre assuntos diversos com os pais e os outros membros que coabitam, relatando também com quem se relacionam melhor em casa. Percebe-se também que a família tenta de alguma maneira moldar-se de acordo com as necessidades da pessoa que tem diabetes,na organização e funcionamento.Sentimentos de gratidão são demonstrados pela associação especializada em educação em diabetes, citada como a responsável por todo ou grande parte do conhecimento adquirido,principalmente pelas atividades oferecidas no acampamento para jovens, e também como fonte de solução de problemas oriundos do diagnóstico do diabetes para os pais e para os próprios adolescentes. / This study aimed to understand how to give the family interactions of adolescents with type 1 diabetes since diagnosis of illness. The method used was Oral History y. Data collected through recorded interviews with seven adolescents were examined in the light of Wright e Leaheys Calgary Family Evaluation Model .Narratives demonstrated that despite the increased activities in the daily routine of the adolescent and family for care and control of diabetes, family interactions experience little change with the arrival of the illness and that conflicts between parents and adolescents with diabetes do not differ from those that occurred between parents and healthy adolescents. Overprotection was a sentiment felt by the teenagers after the onset of the disease because parents have concerns about immediate complications and long term. The main bond shown by the adolescents interviewed with their families was the bond of trust. Adolescents share the diabetes management with brothers superficially, even those who maintain more closed. Extended family also offers contributions in different stages of the disease. The adolescents interviewed communicate with your family is extensive and direct, feeling confident to talk about various issues with parents and other members, also reporting to whom they relate better at home. Family tries shape up according to the needs of the person who has diabetes, the organization and function.

在2型糖尿病病人身上，常常併發高膽固醇血症，HMG CoA 還原酶的抑制劑常常用作治療這類病症。由於高膽固醇血症與胰島素抵抗和2型糖尿病有著密切關係，我們推測辛伐他汀對於2型糖尿病的發展有著保護和有利的作用。在這項研究中，我們主要測試了辛伐他汀 （10 nM； 24 hr）對於胰島β細胞主要功能的影響，包括其對於葡萄糖的胰島素分泌功能影響。我們假設，在肥胖/糖尿病（db⁺/ db⁺）小鼠分離的胰島，辛伐他汀可以恢復葡萄糖 （5 mM和15 mM）引起的胰島素分泌（加上降低的胰島素含量）。 / 在這個項目中，我們運用24周大的基因糖尿糖C57BL/KSJ +db/+db (db⁺/db⁺)肥鼠和相同年齡的無糖尿病C57BL/KSJ +m/+m (db⁺/m⁺)小鼠作為動物模型。通過應用obese/diabetic (db+/db+)和lean/non-diabetic (db+/m+)中分離的胰腺胰島和胰島β細胞，我們研究了胰腺胰島功能性障礙的潛在機理以及辛伐他汀對於恢復葡萄糖 （5 mM和15 mM）引起的胰島素分泌（加上降低的胰島素含量）的有利作用。資料清晰的顯示，葡萄糖引起的胰島素分泌和胰島素含量在obese/diabetic (db+/db+)的胰腺胰島中明顯低於在lean/non-diabetic (db⁺/m⁺)的胰腺胰島中。在24hr的辛伐他汀處理後，辛伐他汀恢復了葡萄糖 （5 mM和15 mM）引起的胰島素分泌（加上降低的胰島素含量）及葡萄糖 （15 mM）引起的胞內鈣離子變化。 / 在這個項目中，我們證明鈣敏感受體 （CaSR）在obese/diabetic (db⁺/db⁺)中的表達量明顯較低，而辛伐他汀的處理可以顯著性增加鈣敏感受體在obese/diabetic (db⁺/db⁺)胰島中的表達。有人建議說，obese/diabetic (db⁺/db⁺)的胰島中被抑制的鈣敏感受體表達與胰島β細胞的胰島分泌功能障礙有關。這暗示了辛伐他汀可能通過變構啟動鈣敏感受體來恢復obese/diabetic (db⁺/db⁺)胰島中葡萄糖引起的胰島素分泌和胰島含量。實驗也同樣証明辛伐他汀調節的PLA₂信號通路對於辛伐他汀改善obese/diabetic (db⁺/db⁺)胰島β細胞的胰島素分泌功能起著至關重要的作用。除此之外，我們的實驗結果證明高濃度的葡萄糖處理顯著的增加了obese/diabetic (db⁺/db⁺)細胞膜肌動蛋白骨架的密度，而辛伐他汀顯著的減少了這一變化。因此，obese/diabetic (db⁺/db⁺)胰島β細胞的胰島素分泌障礙是由肌動蛋白細胞骨架聚集阻礙胰島素顆粒胞吐引起的。而辛伐他汀通過解聚和重組肌動蛋白細胞骨架來改善obese/diabetic (db⁺/db⁺)胰島β細胞的胰島素分泌功能。 / 在這項研究中，我們的實驗結果證明葡萄糖可以顯著提高obese/diabetic (db⁺/db⁺)胰島β細胞內ROS的含量。而辛伐他汀處理部分降低了胰島β細胞內ROS的含量。除此之外，我們還研究了5 mM和15 mM葡萄糖對於內質網應力（ER-stress）相關的蛋白比如PERK, eIF2α 和IRE1表達的影響。這些內質網跨膜蛋白可以感應ER-stress從而啟動應力感測器來開啟複雜的信號通路。與lean/non-diabetic (db⁺/m⁺)相比，PERK and eIF2α在obese/diabetic (db⁺/db⁺)的胰島中表達量更低，這表明obese/diabetic (db⁺/db⁺)胰島β細胞的功能性障礙可能與ER-stress有關。而辛伐他汀的處理明顯的增加了這些蛋白的表達量，由此證明辛伐他汀還通過對抗ER-stress來保護obese/diabetic (db⁺/db⁺)胰島β細胞。 / 總而言之，我們的資料第一次證明了辛伐他汀通過PLA₂信號通路變構啟動鈣敏感受體來保護obese/diabetic (db⁺/db⁺)胰島β細胞（比如：恢復葡萄糖引發的胰島素分泌和提高減少的胰島素含量），還通過提高obese/diabetic (db⁺/db⁺)胰島β細胞中被抑制的ER-stress相關蛋白的表達量來抵抗ER-stress帶來的損傷。 / Diabetics often have hyperlipidemia as a co-morbidity. Despite the well-documented cholesterol-lowering properties of 3-hydroxy-3-methyl-glutaryl coenzyme A (HMG CoA) reductase inhibitors (statins) in treating hypercholesterolemia, the beneficial effects of statins consumption in T2DM treatment are confusing. In the current study, we examined the effects of the simvastatin (10 nM; 24 hr) on β-cell function leading to insulin secretory response to glucose. We hypothesized that statins restore the blunted glucose (5 mM and 15 mM)-induced insulin secretion (plus the reduced insulin content) of isolated pancreatic islets of obese/diabetic (db⁺/db⁺) mice. / In the present study, genetically diabetic C57BL/KSJ +db/+db (db⁺/db⁺) mice at 24 week of age and their age-matched non-diabetic littermates C57BL/KSJ +m/+m (db⁺/m⁺) were used. Our results clearly showed that the suppressed glucose (5 mM and 15 mM)-induced insulin release (plus insulin content) and glucose (15 mM)-induced [Ca²⁺]i changes of isolated pancreatic islets of obese/diabetic (db⁺/db⁺) was restored after simvastatin (10 nM; 24 hr) treatment. / The biochemical existence of CaR in pancreatic islets of lean/non-diabetic (db⁺/m⁺) and obese/diabetic (db⁺/db⁺) mice was confirmed. The suppressed/down-regulated expression of CaR was associated to the blunted insulin secretion in pancreatic β-cells of obese/diabetic (db⁺/db⁺) mice, and it was markedly up-regulated by simvastatin (10 nM; 24 hr). The involvement of CaR-mediated PLA₂ signaling in simvastatin (10 nM; 24 hr)-induced restoration of glucose (15 mM)-induced insulin secretion in pancreatic β-cells of obese/diabetic (db⁺/db⁺) mice was investigated. Our results also showed that the increased density of plasma membrane actin cytoskeleton of obese/diabetic (db⁺/db⁺) mice was significantly decreased by simvastatin (10 nM; 24 hr) treatment. The simvastatin-induced depolymerization and remodeling of actin cytoskeleton may improve insulin secretion capability in pancreatic β-cells of obese/diabetic (db⁺/db⁺) mice. / The glucose (15 mM)-induced intracellular ROS level was significantly higher in pancreatic β-cells of obese/diabetic (db⁺/db⁺) mice. The elevated ROS level was partially diminished by simvastatin (10 nM; 24 hr) treatment. The protein expressions of PERK and eIF2α (ER stress proteins) were lower in pancreatic islet cells isolated from obese/diabetic (db⁺/db⁺) mice, suggesting that abnormal expresstion/activity of PERK and eIF2α would be coupled to the ER-stress mediated failure of pancreatic β-cells of obese/diabetic (db⁺/db⁺) mice. As simvastatin (10 nM; 24 hr) up-regulated the protein expression of these proteins, this drug exerted protective effect on pancreatic β-cells against ER stress and restored the blunted glucose (15 mM)-induced insulin secretion (plus the reduced insulin content) in obese/diabetic (db⁺/db⁺) mice. / In conclusion, our results demonstrate, for the first time, that simvasatatin (a HMG-CoA reductase inhibitor) (10 nM; 24 hr) provides beneficial effects (i.e. restoration of the blunted glucose-induced insulin release plus the reduced insulin content) in pancreatic β-cells of obese/diabetic (db⁺/db⁺) mice via the allosteric modification/up-regulation of extracellular calcium-sensing receptor through the PLA₂ signaling pathway, and provides protective/antioxidant effects against oxidative stress caused by chronic hyperglycemia in pancreatic β-cells of obese/diabetic (db⁺/db⁺) mice by up-regulating protein expression of the suppressed ER stress sensors and antioxidant enzyme. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Au, Lai Shan. / Thesis (Ph.D.) Chinese University of Hong Kong, 2013. / Includes bibliographical references (leaves 458-532). / Abstracts also in Chinese.

alpha-Glucosidase from yeast was used to screen for alpha-glucosidase inhibitory activities in Chinese herbal medicines. Seventy crude extracts were studied. The extracts of Semen Fagopyri Esculenti, Herba Euphorbiae Humifusae, Radix Polygoni Multiflori, Cortex Cinnamomi, Radix Paeoniae Rubra, and Radix Paeoniae Alba exhibited alpha-glucosidase inhibitory activities. These herbs have high potential for finding active compounds to develop into new antidiabetic drugs. / In this study, an assay technique involving brush border membrane vesicles was developed to screen for glucose uptake inhibitory actions in sixteen compounds from natural sources. Two compounds, namely naringenin and desoxyrhaponticin, were demonstrated to exhibit moderate inhibitory action on glucose uptake in rabbit intestinal brush border membrane vesicles, and showed very strong inhibitory action in rat everted intestinal sleeves. The kinetics study indicated that they behave as competitive inhibitors on glucose uptake. Moreover, they could reduce the level of the glucose uptake in the diabetic rat intestinal and renal membrane vesicles. In vivo study further demonstrated that desoxyrhaponticin could significantly reduce the glucose levels after a single oral administration of glucose in neonatal streptozotocin-induced diabetic rats, but not naringenin. These results suggest that naringenin and desoxyrhaponticin may be useful in the control of hyperglycemia. They act by inhibiting glucose uptake in the intestine and glucose reabsorption in the renal proximal tubules. / On the other hand, several synthetic compounds based on the structure of valienamine were found to show strong inhibition on intestinal alpha-glucosidases such as sucrase, glucoamylase and maltase. The strongest inhibitor was further studied. It could reduce the postprandial plasma glucose level of neonatal streptozotocin-induced diabetic rats. These results demonstrated that it has the potential to develop inter an oral antihyperglycemic agent. / The objective of this study is to improve the postprandial hyperglycemic conditions of diabetes by two approaches: (1) inhibiting the digestive enzymes (alpha-glucosidases), and (2) inhibiting active glucose transport in the small intestine. We have screened for new inhibitors of alpha-glucosidase and monosaccharide cotransporters from natural products and their derivatives. These compounds may be useful in the management of type 2 diabetes and diabetic complications. / Type 2 diabetes mellitus accounts for 90-95% of all diabetic cases and has become a major health concern over the world. There is increasing evidence that postprandial hyperglycemia, a hallmark of diabetes, plays a critical role in the development of type 2 diabetes and cardiovascular complications. Therefore the early identification of postprandial hyperglycemia and its effective control can offer the potential for early intervention and prevention of diabetic complications. / Li Jianmei. / "August 2006." / Adviser: Christopher H.

The aim of the present study was to investigate the influence of insulin-dependent diabetes mellitus (IDDM) on the cognitive functioning, learning difficulties, and behavioral problems in children between the ages of 7 and 12. The sample was composed of elementary school children living in Ankara, Turkey. Data was collected by administering demographic information form, Children&rsquo / s Depression Inventory (CDI), Strength and Difficulties Questionnaire (SDQ), Wechsler Intelligence Scale for Children&ndash / Revised (WISC-R), and Specific Learning Disability Scale. One-way ANOVAs were employed to examine the differences among the levels of parental education, income, school achievement, and child&rsquo / s adherence to IDDM in terms of WISC-R scores, learning difficulty related variables, behavioral problems, and depression. Results revealed that children with low adherence to IDDM were more likely to experience behavioral problems and depression. T-tests were conducted to examine the mean differences between IDDM and control groups in terms of WISC-R scores, and the variables related to learning difficulties, behavioral problems, and depression. As compared to control group, children with IDDM had lower WISC-R information, similarities, arithmetic, and total scores. Also, children with IDDM had lower achievement in several arithmetic, reading, and writing tasks. Furthermore, hierarchical multiple regression analyses were conducted to test the effect of IDDM adherence, age of onset, and illness duration on cognitive functioning, learning, and behaviors. The results did not reveal any significant effect of IDDM related variables on children&rsquo / s cognitive functioning, learning, or behaviors. Findings were discussed with reference to the relevant literature. Implications of the study were discussed and future research topics were suggested.
