BACKGROUND: Puguntano (Curanga feel-terrae Merr.) contains flavonoids, saponins, tannins, and steroids/ terpenoids which improved post-receptor insulin signalling in rats model of type 2 diabetes mellitus (T2DM). AIM: This study aimed to determine the effect of puguntano leaf extract on p38 mitogen-activated protein kinase (MAPK) levels and glucose transporter-4 (GLUT-4) expression in diabetic rats muscle. METHODS: Forty-eight male Wistar rats had T2DM induced using a combination of feeding a high-fat diet for 5 weeks and multiple intraperitoneal injections of low-dose streptozotocin (30 mg/kg). The diabetic rats were randomly divided into control and treatment groups, and 200 mg/kg/day puguntano extract was administered orally for 10 days to treatment group. Subsequently, p38 MAPK levels were measured by Sandwich Elisa and plasma membrane GLUT-4 expression was evaluated by Immunohistochemistry in their gastrocnemius muscles. RESULTS: There were significantly higher p38 MAPK levels and GLUT-4 expression in the treatment group than in the control group. CONCLUSION: These data suggest that a puguntano leaf extract can improve post-receptor insulin signalling by enhancing p38 MAPK levels and GLUT-4 expression in a rat model of T2DM.

ABSTRACT Objective: Adiponectin receptors (AdipoR) regulates metabolism and has anti-inflammatory and insulin-sensitizing effects. We aimed to determine the relationships between AdipoR with parameters of glucose homeostasis (FPG, insulin, and HOMA-IR), and insulin sensitivity (PPAR-γ and p38MAPK) in T2DM rats treated with puguntano (Curanga felterrae Lour.) leaf extract. Methods: T2DM was induced in Wistar rats aged 8–10 weeks and weighing 180–200 g by high-fat diet (HFD) feeding and low-dose streptozotocin (30mg/kg.bw) administration. The rats were then allocated randomly to a treatment group and a control group (n=24 each). The treatment group was orally administered puguntano leaf extract (200 mg/kg.bb) once daily for 10 days. Subsequently, FPG and plasma insulin were measured, and HOMA-IR was calculated. Results: There was significantly difference between treatment group and control group on AdipoR and parameter of glucose homeostasis (FPG, Insulin, HOMA-IR) and insulin sensitivity (PPAR-γ,  p38MAPK (all, p<0.01). In both groups, there were no significantly correlations between of AdipoR with all parameter of glucose homeostasis and insulin sensitivity except PPAR-ϒ (p <0.003) across the entire cohort of rats. Conclusion: Our data suggest that puguntano could improve glucose homeostasis, insulin sensitivity and molecular mediators of insulin sensitivity. There were no significantly correlated between improvement of AdipoR with glucose homeostasis and molecular mediators of insulin sensitivity in T2DM.

BACKGROUND: Defects in post-receptor insulin signalling are the major cause of insulin resistance in type 2 diabetes mellitus (T2DM). AIM: This study aimed to investigate the correlations between insulin receptor substrate (IRS)-1 with phosphoinositide 3-kinase (PI3K) and p38 mitogen-activated protein kinase (MAPK) levels after puguntano (Curanga fel-terrae [Merr.]) leaf extract treatment in a rat model of T2DM. METHODS: A combination of high-fat diet-feeding (HFD) and multiple low dose intraperitoneal injections of streptozotocin was used to induced T2DM in 48 Wistar rats, which were then randomly divided into control and treatment groups (n = 24 per group). Puguntano leaf extract was administered to the treatment group once daily (200 mg/kg.bw) for 10 days. IRS-1, PI3K and p38 MAPK levels were measured in skeletal muscle using sandwich ELISAs in control group after becoming T2DM and in the treatment group after 10 days of puguntano treatment. Data were analysed using the Wilcoxon test and Spearman’s correlation. RESULTS: IRS-1, PI3K and p38 MAPK levels were significantly higher in the treatment group than in the control group. There were also significant positive correlations between IRS-1 with PI3K and p38 MAPK levels (r = 0.375, p = 0.035; r = 0.552, p = 0.003; respectively) after the treatment. CONCLUSION: This study demonstrated significant positive correlations between IRS-1 with PI3K and p38 MAPK levels after puguntano leaf extract treatment of T2DM rats.

Oxidative stress in a patient with diabetes known to decrease the activity of GSH-PX and increase the level of blood glucose. Glibenclamide is commonly used by patients with diabetes to lower the blood glucose. However, the long-term use of glibenclamide may induce the damage of pancreatic β-cells. The extract containing flavonoids and vitamin C of cardamoms leaf can reduce free radicals. The effect of cardamoms leaf extract on the enzymes activity and the level of blood glucose in diabetic rats is yet unknown. The aim of this study was to examine the effect of cardamoms leaf extract administration in the GSH-PX activities and the level of blood glucose of diabetic rats. The method used in this study was experimental with completely randomized design (CRD). There were three groups with five replicates for each. The first group, diabetic rats as control group were given no treatment; the second group, diabetic rats were given cardamoms leaf extract at the dose of 100 mg/kg of body weight; the third group, the diabetic rat were given glibenclamide at the dose of 2 mg/kg of body weight. Blood samples were taken three times at 0, 7, and 14 days after each treatment. Parameters measured were GSH-PX activity and the level of blood glucose. The data were analyzed using ANOVA F-test with a confidence level of 95%. The result of this study showed that the cardamoms leaf extract treatment decreased the activity of GSH-PX activity and decreased the level of blood glucose at a significant level (p < 0.05) from 278.8 to 101.4 mg/dl.

Background and Aims: In the current work, we studied the effects of exercise and stevia rebaudiana (R) extracts on diabetic cardiomyopathy (DCM) in type 2 diabetic rats and their possible underlying mechanisms. Methods: : Thirty-two male Sprague Dawley rats were randomly allocated into 4 equal groups; a) normal control group, b) DM group, type 2 diabetic rats received 2 ml oral saline daily for 4 weeks, c) DM+ Exercise, type 2 diabetic rats were treated with exercise for 4 weeks and d) DM+ stevia R extracts: type 2 diabetic rats received methanolic stevia R extracts. By the end of the experiment, serum blood glucose, HOMA-IR, insulin and cardiac enzymes (LDH, CK-MB), cardiac histopathology, oxidative stress markers (MDA, GSH and CAT), myocardial fibrosis by Masson trichrome, the expression of p53, caspase-3, α-SMA and tyrosine hydroxylase (TH) by immunostaining in myocardial tissues were measured. Results: T2DM caused a significant increase in blood glucose, HOMA-IR index, serum CK-MB and LDH, myocardial damage and fibrosis, myocardial MDA, myocardial α-SMA, p53, caspase-3, Nrf2 and TH density with a significant decrease in serum insulin and myocardial GSH and CAT (p< 0.05). On the other hand, treatment with either exercise or stevia R extracts significantly improved all studied parameters (p< 0.05). Moreover, the effects of stevia R was more significant than exercise (p< 0.05). Conclusion: Both exercise and methanolic stevia R extracts showed cardioprotective effects against DCM and Stevia R offered more cardioprotective than exercise. This cardioprotective effect of these lines of treatment might be due to attenuation of oxidative stress, apoptosis, sympathetic nerve density and fibrosis and upregulation of the antioxidant transcription factor, Nrf2.

AbstractObjectivesType 2 diabetes is a common metabolic disease and anxiety disorders are very common among diabetics. Buspirone is used in the treatment of anxiety, also having blood glucose-lowering effects. The aim of the study was to investigate the effects of buspirone on the glucose and lipid metabolism as well as vascular function in type 2 diabetic rats.MethodsA type 2-diabetic model was induced through a high-fat diet for eight weeks followed by the administration of low-dose streptozotocin (35 mg/kg, intraperitoneal) in rats. Buspirone was given at two different doses (1.5 mg/kg/d and 5 mg/kg/d) and combined with metformin (300 mg/kg/d). The fasting glucose and insulin levels, lipid profile were analyzed, and vascular response measured from the thoracic aorta was also evaluated.ResultsBoth doses of buspirone caused a significant improvement in fasting blood glucose levels. In particular, the buspirone treatment, combined with metformin, improved endothelial dysfunction and was found to be correlated with decreased nitrate/nitrite levels.ConclusionsBuspirone may be effective in the treatment of type 2 diabetes, either alone or in combination with other treatments, particularly in terms of endothelial dysfunction, inflammation and impaired blood glucose, and insulin levels.

PURPOSE: To compare body weight and length, heart weight and length, heart-to-body weight ratio, glycemia, and morphometric cellular data of offspring of diabetic rats (ODR) and of normal rats (control). METHODS: Diabetes was induced in 3 pregnant Wistar rats, bearing 30 rats, on the 11th day after conception by intraperitoneal injection of 50 mg/kg of streptozotocin. Six normal pregnant Wistar rats, bearing 50 rats, made up the control group. Morphometric data were obtained using a scale for the weight, length, heart and body measurements. Morphometric cellular data were obtained by a computer assisted method applied to the measurements of myocytes. Statistical analysis utilized Student's t-test, ANOVA and Levene test. RESULTS: Control offspring had greater mean body weight and length than offspring of diabetic rats (p < 0.001). Heart weight and length and heart-to-body ratios of newborn rats differed between groups at birth (p < 0.001), but showed no difference at 21 days. Mean nuclei area and perimetric value of the myocytes decrees throughout the first 21 days of life (p < 0.01) in the diabetic group. CONCLUSIONS: Heart hypertrophy on the offspring of diabetic rats at birth was demonstrated by the significant difference between the groups. After the eleventh day, no difference was found, which confirmed regression of cardiomegaly. The significant difference between the first and the 21th day of life, for nuclei area feature, demonstrate regression of cardiac hypertrophy in the offspring of diabetic rats.

A well-balanced diet is one of the four pillars of diabetes self-management. Patient's culture strongly influences intake food. Diabetic dietary guidelines which fit with the patient's culture is expected to improve patient's self-efficacy and diet compliance. This study was aimed to analyze the effect of ethnic foods diet program in improving self-efficacy and diet compliance among Type-2 Diabetes Mellitus (T2DM) patients. This was quasy experiment research with pre and post-test control design. The population was 112 T2DM patients from Sasak Tribes, West Nusa Tenggara. Samples were 36 respondents, divided into intervention (18) and control (18) groups. The independent variable was the ethnic food diet (EFD) program, while the dependent variables were patient's self-efficacy and diet compliance. Data were collected using self-efficacy questionnaire and a 24-hour dietary recall form. Data were then analyzed using Wilcoxon Signed Rank Test and Mann Whitney U Test. The result showed differences in self-efficacy between pre and post-test in the treatment group (p=0,001), but there were no differences in the control group. There were differences in diet compliance in the treatment group (p=0,001), but there were no differences in the control group. There were differences between treatment and control groups on self-efficacy (p=0,000) and diet compliance (p=0,000). Ethnic foods diet program can improve self-efficacy and diet compliance among T2DM patients because more comfortable and easier to be applied. Nurses can apply ethnic foods diet program as an intervention to promote healthy diet for T2DM patients.

Fenofibrate Treatment

Abstract Background: This study was to research the efficacy of fenofibrate in the treatment of microalbuminuria in the patients with type 2 diabetes mellitus (T2DM) and hypertriglyceridemia. Methods: Type 2 diabetic patients (56) with microalbuminuria and hypertriglyceridemia aged 30 to 75 were randomly divided into the fenofibrate treatment group(n=28) and the control group (n=28) for 180 days. Urinary microalbumin /creatinine ratio (UACR) and other metabolic parameters were compared at baseline, during treatment and after treatment. Results: After 180 days, the reduction of levels of fasting blood glucose (FBG) and glycosylated hemoglobin (HbA1c) in two groups were no differences. In treatment group, uric acid (UA) (296.42 ± 56.41 vs 372.46 ± 72.78), triglyceride (TG) [1.51(1.17, 2.06) vs 3.04(2.21, 3.29)], and UACR [36.45 (15.78,102.41) vs 129.00 (53.00, 226.25)] were significantly decreased compared with the baseline. The high-density lipoprotein cholesterol (HDL-C) levels were significantly increased (1.22 ± 0.26 vs 1.09 ± 0.24) compared with the baseline. The decrease in UACR [-44.05(-179.47, -12.16) vs -8.15(-59.69, 41.94)]in treatment group was significantly higher compared with the control group. The decrease in UACR was positively associated with the decreases in TG ( r = 0.447, P = 0.042) and UA ( r = 0.478, P = 0.024) after fenofibrate treatment. Conclusion: In the patients with hypertriglyceridemia and type 2 diabetes mellitus, fenofibrate can improve microalbuminuria and do not increase the deterioration of glomerular filtration rate
