In China, TianMai Xiaoke tablet (TM) is used to treat type 2 diabetes. However, the exact mechanism of TM is not clear. This study is to investigate the effect of TM on glucose metabolism in diabetic rats and to identify whether TM takes a direct action through microRNAs on islet. Rats were divided into control group, diabetic group, low dose of TM group (TML), and high dose of TM group (TMH). Pancreas samples were analyzed using microRNA array and Q-PCR. Eight-week treatment with TM significantly decreased fasting blood glucose. The blood glucose was significantly reduced in TM-treated groups before and after oral glucose administration. Fasting insulin and HOMA-IR were suppressed in TM-treated groups. miR-448, let-7b, miR-540, miR-296, miR-880, miR-200a, miR-500, miR-10b, miR-336, miR-30d, miR-208, let-7e, miR-142-5p, miR-874, miR-375, miR-879, miR-501, and miR-188 were upregulated, while miR-301b, miR-134, and miR-652 were downregulated in TMH group. Through target gene analysis and real-time PCR verification, we found that these miRNAs, especially miR-375 and miR-30d, can stimulate insulin secretion in islet. Our data suggest that TM can improve blood glucose in diabetic rats which involved increasing the expression of miR-375 and miR-30d to activate insulin synthesis in islet.

  Objective: This study was conducted to scientifically evaluate the antidiabetic and antioxidant effects of ethanolic leaf extract of Erythrina abbysinica (EEA).Methods: Acute and sub-chronic effects of EEA at 100, 200, and 400 mg/kg/bwt and glibenclamide (GL) at 5 mg/kg/bwt. were evaluated in both normal and streptozotocin (STZ)-induced diabetic male Wistar rats (250–300 g). The acute studies were performed using oral glucose tolerance test (OGTT). In sub-chronic studies, animals were orally administered with EEA and GL daily for 6 w. Brine shrimp assay was used to determine the toxicity of EEA. 1, 1-diphenyl-2-picrylhydrazyl, ferric reducing capacity of plasma, and thiobarbituric acid reactive substances assays were used to determine antioxidant properties of EEA.Results: Following OGTT, EEA significantly (p<0.05) and dose-dependently (100, 200, and 400 mg/kg/bwt) decreased blood glucose levels in both normal and STZ-induced diabetic rats when compared with positive and negative control counterparts at all-time points, whereas GL significantly (p<0.05) decreased blood glucose only in normal rats but not in diabetic rats. Daily, oral administration of EEA for 6 w significantly (p<0.05) and dose-dependently (100, 200, and 400 mg/kg/bwt) decreased blood glucose levels in STZ-induced diabetic rats when compared with the diabetic control group. EEA revealed weak toxicity with a lethal concentration50 value of 997 μg/ml). Furthermore, EEA showed significant free radical scavenging, total antioxidant, and anti-lipid peroxidative capacities.Conclusion: The study has shed more light on the scientific basis for the use of E. abbysinica in management of diabetes in some communities of Eastern Cape of South Africa.

This study investigated the effects of polysaccharides fromEnteromorpha prolifera(PEP) on glucose metabolism in a rat model of diabetes mellitus (DM). PEP (0, 150, 300, and 600 mg/kg) was administered intragastrically to rats for four weeks. After treatment, fasting blood glucose (FBG) and insulin (INS) levels were measured, and the insulin sensitivity index (ISI) was calculated. The morphopathological changes in the pancreas were observed. Serum samples were collected to measure the oxidant-antioxidant status. The mRNA expression levels of glucokinase (GCK) and insulin receptor (InsR) in liver tissue and glucose transporter type 4 (GLUT-4) and adiponectin (APN) in adipose tissue were determined. Compared with the model group, the FBG and INS levels were lower, the ISI was higher, and the number of isletβ-cells was significantly increased in all the PEP groups. In the medium- and high-dose PEP groups, MDA levels decreased, and the enzymatic activities of SOD and GSH-Px increased. The mRNA expression of InsR and GCK increased in all the PEP groups; APN mRNA expression increased in the high-dose PEP group, and GLUT-4 mRNA expression increased in adipose tissue. These findings suggest that PEP is a potential therapeutic agent that can be utilized to treat DM.

Aim: Antioxidants, such as vitamin C and vitamin E, is widely used as supplements. The aim of this study is to analyze the profile of blood glucose, serum insulin, and  HOMA in active teenagers after vitamin C and vitamin E supplementation.Methods: Subjects (14-16 y.o) consisted of 12 boys and 5 girls, divided into 3 groups: control (4 boys, 2 girls), ‘moderate dose’ of vitamin C and vitamin E combination group (5 boys, 1 girls), and ‘high dose’ of vitamin C and vitamin E combination group (3 boys, 2 girls). The treatment was given for 5 days. Vitamin C and vitamin E for ‘moderate dose’ was 500mg;  200IU, and for ‘high dose’ was 1000mg; 400IU. Fasting Blood Glucose (FGB) and 1 hour BG (1hr_BG), fasting serum insulin (FSI) and 1 hour SI (1hr_SI) was collected after treatment. We also calculated the HOMA-IR and HOMA-β.Result: There was no significant difference on FBG, 1hr_BG, FSI, 1hr_SI, HOMA-IR, and HOMA-β (p≥ 0.05). However, mean FBG and 1hr_BG tended to be higher on the treatment groups. The control group had the lowest HOMA-IR and the highest HOMA-β.Conclusions: We suggest that the supplementation of vitamin C and vitamin E in active teenagers is not essential on glucose homeostasis.

Some lactic acid bacteria (LAB) are observed to be potential probiotics with functional properties such as lowering fasting blood glucose (FBG), as a promising hyperglycemia management. This study investigated the ability and mechanism of Lactobacillus rhamnosus BSL and Lactobacillus rhamnosus R23 on lowering FBG in diabetic rats induced by streptozotocin (STZ). The rats were orally administered with L. rhamnosus BSL and L. rhamnosus R23 by giving 1 mL cell suspension (109 CFU/mL) daily for 30 days. The body weight (BW) was recorded once in three days, and FBG was recorded once in six days. An oral glucose tolerance test (OGTT) was measured 1 week after injection with STZ and before sacrifice. Fecal samples were collected on days 0, 15, and 30 for LAB population and identification, performed by PCR detecting 16S rRNA. Oral administration of L. rhamnosus BSL and L. rhamnosus R23 decreased FBG and improved glucose tolerance via downregulation of glucose-6-phosphatase (G6pc) expression by 0.57- and 0.60-fold change, respectively (P<0.05). The lipid profiles, BUN, creatinine, SGOT, and SGPT were significantly (P<0.05) different between normal and diabetic rats, but they were not significantly (P>0.05) different among diabetic rats. Both strains were effective in increasing fecal LAB population. Molecular identification of the isolated LAB from fecal sample indicated that they were able to survive and pass through the digestive tract. These results suggested that both strains have the ability to manage blood glucose level and become a promising agent to manage hyperglycemia and diabetes.

Objective. As a complicated symbiotic system, intestinal flora is reported closely related to the development of type 2 diabetes recently. Sleeve gastrectomy is one of the approaches of bariatric surgery and could improve blood glucose control in type 2 diabetes patients. This study was to explore the relationship between remodeled intestinal flora and glucose metabolism in diabetic rats.Methods. 20 male diabetic rats were operated; 10 of them underwent sleeve gastrectomy, and 10 of them underwent sham operation. Meanwhile 10 male normal rats underwent sleeve gastrectomy as control. The animals’ weight and FBG had been measured. The composition changes of intestinal flora were detected by 16S rDNA sequence analysis.Results. In diabetic rats, weight and fasting blood glucose decreased significantly after sleeve gastrectomy. However, there was no significant change for weight and blood glucose in normal rats after operation. The intestinal flora of diabetic rats reduced in the proportion of Firmicutes and increased in the proportion of Bacteroidetes after sleeve gastrectomy.Conclusion. The change of dominant microorganisms in intestinal flora might play an important role in the glucose metabolism.

Background: Flavonoids, saponins, tannins, phenols, and vitamin-C contained in the Red Dragon fruit’s skin have a positive impact on glycemic control and lipid oxidation. This study aimed to determine the effect of Red Dragon fruit’s skin extract on reducing the fasting blood glucose (FBG) and improving the lipid profile of Wistar rats with diabetes and dyslipidemia. Methods: A randomized pre-test post-test control group experimental study was done on 22 male Wistar rats, aged 2-3 months that suffered from diabetes and dyslipidemia. Subjects were divided into the control group (given 2cc distilled water + 9 mg metformin) and the treatment group (given 160 mg red dragon fruit’s skin extract + 9 mg metformin) for 14 days. FBG and lipid profile measurements were done before and after the treatment. Data were analyzed using the compare mean test. Results: There was no significant mean difference of GDP between groups before (p=0.414) and after treatment (p=0.125), total cholesterol between groups before (p = 0.572) and after treatment (p=0.361), triglycerides between groups before (p=0.073) and after treatment (p=0.111). There was a significant mean difference of HDL between groups before (p=0.003) and after treatment (p=0.047), LDL between groups before (p=0.006) and after treatment (p=0.043). Although there were significant mean differences in HDL and LDL between groups before and after treatment, the pre-post treatment of HDL and LDL mean differences showed no significant mean difference (p=0.328 and p=0.704 consecutively). Conclusion: Red Dragon fruit’s skin extract treatment did not significantly reduce the mean FBG and lipid profile levels.

Hyperglycemia causes increased oxidative stress through an imbalance of reactive oxygen species and antioxidative mechanisms. It stimulates the production of inflammatory mediators and cytokines such as TNF-α, interleukin (IL)-1, and IL-18. Goat milk kefir and vitamin D3 have potential as antioxidants and anti-inflammatory agents that can repair damage to pancreatic β cells. This study analyzed the effects of goat milk kefir fortified with vitamin D3 on the IL-18 level in diabetic rats. An experimental randomized pre-post test with control group design was conducted on 20 male Wistar rats divided into four groups, namely negative control (K-), positive control (K+), treatment with unfortified kefir (P1), and treatment with kefir fortified with vitamin D3. The intervention lasted 34 days. Fasting blood glucose and IL-18 levels were measured before and after intervention. Blood glucose and IL-18 levels were analyzed using the glucose oxidase p-aminophenol method and enzyme-linked immunosorbent assay, respectively. No significant increase in the IL-18 level was found in the P1 group with a median of 56.5 (10–252.7) pg/mL to 148.2 (106.8–428.3) pg/mL (p = 0.465) or P2 group with a median of 117.3 (91.8–146.8) pg/mL to 246.7 (168.8–311) pg/mL (p = 0.068), and no significant increase was observed in blood glucose levels in the P1 group (366.9±134.8 mg/dL to 462.1±156.9 mg/dL, p = 0.357) or P2 group (415.0±203.8 mg/dL to 258±129 mg/dL, p = 0.463). Goat milk kefir fortified with vitamin D3 could maintain blood glucose and IL-18 levels.
