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.

Abstract Background Diabetes, a global cause of mortality in developing countries is a chronic disorder affecting the metabolism of macromolecules and has been attributed to the defective production and action of insulin characterized by persistent hyperglycemic properties. This global disorder harms organs of the body such as the liver, kidney and spleen. Medicinal plants such as Hunteria umbellate have been shown to possess hypoglycemic, antioxidative and anti-diabetic properties owing to the high concentration of active phytochemical constituents like flavonoids and alkaloids. The present study seeks to evaluate the hypoglycemic activities of ethanolic seed extract of Hunteria umbellate on streptozotocin-induced diabetes rats. Methods Thirty (30) female experimental rats were randomly divided into five groups with six rats per group and were administered streptozotocin (STZ) and Hunteria umbellate as follows. Group 1 served as control and was given only distilled water, group 2 rats were administered 60 mg/kg STZ; Group 3 was administered 60 mg/kg STZ and 100 mg/kg metformin; group 4 rats were administered 60 mg/kg STZ and 800 mg/kg Hunteria umbellate, group 5 rats 60 mg/kg STZ and 400 mg/kg Hunteria umbellate. The fasting blood glucose level of each rat was measured before sacrifice. Rats were then sacrificed 24 h after the last dose of treatment. Results The results showed that Hunteria umbellate significantly reversed STZ-induced increase in fasting blood glucose and increase in body and organs weight of rats. Hunteria umbellate significantly reversed STZ-induced decrease in antioxidant enzyme in liver, kidney and spleen of rats. Hunteria umbellate significantly reversed STZ-induced increase in oxidative stress markers in liver, kidney and spleen of rats. Conclusion Collectively, our results provide convincing information that inhibition of oxidative stress and regulation of blood glucose level are major mechanisms through which Hunteria umbellate protects against streptozotocin-induced diabketes rats.

A raised blood sugar level no more defines a single entity than does a raised bilirubin or a low haemoglobin. Diabetes is a heterogenous group of disorders whose only common factor is hyperglycaemia (Tattersallet al, 1980). The classification of diabetes is being revised, although the changes are of more relevance to epidemiologists than clinicians. Previous standards of normal glucose tolerance were set too low, so that some people were labelled diabetic who had no symptoms and have proved on follow-up not to be at risk of developing complications such as retinopathy (i.e. they had a non-disease). Epidemiological evidence suggests that the cut-off point for ‘true’ diabetes (i.e. a condition which leads to complications and shortening of life span) is a blood glucose level two hours after a 50 G oral glucose load of 11.1 mMol/L (National Diabetes Data Group, 1979). This corresponds to a fasting blood glucose level of 7 mMol/L or below. Hence, a single blood glucose value, either in the fasting state or two hours after a 50 G glucose load, is enough to diagnose diabetes and glucose tolerance tests should hardly ever be necessary.

The aim of this study is the evaluation of the effect of Afghan talkhak (Acroptilon Repens) root aqueous extract on blood glucose level of diabetic rats. Rats were randomly divided into 5 groups (1 Normal, 1 Diabetic and 3 extract groups). Experimental diabetes was induced by single-dose intraperitoneal (i.p.) injection of streptozotocin (55 mg/kg) in diabetic and extracts groups. 72 hour later, the induction of diabetes was approved and extract groups were received Acroptilon Repens aqueous extract (200, 300, 400 mg/kg) by i.p. administration for 15 days. The blood glucose level and body weight of all groups were measured on baseline, 0, 5, 10 and 15th days. The glucose tolerance test had performed on days 0 and 15. The results showed that aqueous extract of Afghan Acroptilon Repens in extract groups (200 and 300 mg/kg) could significantly decrease the blood glucose level, and improve the glucose tolerance, as compared with the diabetic group (P<0.0001). However, there was not a significant difference in the blood glucose level and glucose tolerance test among the group which received 400 mg/kg dose of Acroptilon Repens and the diabetic group (P>0.05). In conclusion, Acroptilon Repens root aqueous extract possessed antihyperglycemic activity.

Background: The anti-hyperglycemic potential of methanol stem bark extract of Anacardium occidentale (MSBEAO) was investigated using an alloxan-induced diabetic rat model. Alloxan administration induces the generation of free radicals which can affect antioxidant status resulting in the disruption of the β-cells of the pancreas. Therefore, this study examines the antioxidant potential of the plant extract and the ameliorating effect on the pancreas of alloxan-induced diabetic rats. Methods: Diabetes was induced by intraperitoneal injection of 150 mg/kg body weight of alloxan monohydrate. MSBEAO, at a concentration of 100 or 200 mg/kg b.w. was orally administered to alloxan-induced diabetic rats and normal rats. The hypoglycemic effect, oral glucose tolerance test, and biochemical assay of alloxan-induced diabetic rats were assayed using standard procedures. Results: Preliminary phytochemical screening of the extract revealed the presence of alkaloids, tannins, saponins, terpenoids, carbohydrates, and phenols at moderate concentrations. The lethality dose (LD50) of the plant extract was found to be equal to or less than 5000 mg/kg b.w. The hypoglycemic effect of the extract on the non-diabetic rats revealed a significant (p<0.05) decrease in the blood glucose concentration of animals administered with 1 g/kg b.w. of the extract, compared to normal control rats administered with normal saline. In the oral glucose tolerance test, the methanol extract exerted the highest response, similar to glibenclamide after 15 and 30 minutes of administration, compared to the control rats. The methanol extract yielded the highest blood glucose lowering effects after 9 days of treatment (p<0.05), compared to diabetic rats administered with normal saline and 0.3 mg/kg b.w. of glibenclamide. Administration of the extract at 200 mg/kg b.w. showed improved pancreas architecture and regeneration of the β-cells, compared with the pancreas of animals in the other groups. Conclusion: The results of this study suggest that MSBEAO is a potentially effective agent for the management of diabetes which might result from the antioxidant-generating capacity of the stem bark.

Introduction: Gestational diabetes mellitus is common disorder in pregnancy. It is associated with adverse pregnancy outcome. There is no consensus regarding the optimal approach to screening of gestational diabetes mellitus. The present study has tried toobserve the value of fasting blood glucose in screening of gestational diabetes. Objective: To determine the frequency of patients in whomfasting blood glucose and 100gm glucose tolerance show agreement for screening of gestational diabetes mellitus at 24 -28 wks. Studydesign: Comparative cross sectional study. Settings: The study was conducted at Gynecology and Obstetrics department Shaikh ZayedFederal Post Graduate Institute Lahore. Duration of study with dates: 6 months from 12Nov 2010 to 11 May 2011. Material and method: Thestudy included 135 booked patients with positive family history of diabetes mellitus. All patients underwent fasting blood glucose at 24-28 weeksof gestation, regardless of results of fasting blood glucose on next visit they underwent 100g oral glucose tolerance test (OGTT). The agreementbetween fasting blood glucose and 100g oral glucose tolerance test was calculated in frequency and percentages. Results: The mean age ofwomen in studied population was 27.15±3.70.Out of 135 patients 86.7 %( 117) showed agreement between results of fasting blood glucose and100g OGTT while 13.31 %( 18) showed no agreement between both of the tests. Conclusions: Fasting blood glucose is a good screeningoption for gestational diabetes mellitus along with positive history. It provides a simple, cheap and more practical test for screening of gestationaldiabetes mellitus. However diagnostic confirmation with 100g OGTT should be done.

Madam F. Kayes Bitters® is an herbal formulation commonly used in Nigeria and some African countries in the management of diabetes mellitus and other diseases conditions. This study evaluated the in-vivo hypoglycaemic activity, as well as acute toxicity of the polyherbal formulation to provide its efficacy and safety. Healthy albino mice (20-30 g) and Sprague Dawley female rats (90-130 g) were used for this study. Acute toxicity study (LD50) of the herbal formulation was determined by methods originally described by Miller and Tainter in 1994. Following oral dosing with glucose (2 g/kg) in normal fasted animals, herbal formulation (HF) at various doses was administered and blood glucose levels at 30 minutes, 60 minutes, 90 minutes, and 120 minutes were taken and recorded. Diabetes was induced using alloxan 150 mg/kg and diabetic rats were given the HF at doses of 50, 100, and 200 mg/kg with glibenclamide 2.5 mg/kg used as standard drug treatment. Blood glucose level was determined on 1st day, 7th day, 14th and 21st day. The LD50 was greater than 5g/kg with oral administration. The oral glucose tolerance test showed that the group that received 100 mg/kg HF showed a significant reduction (p<0.05) in glucose level after 120 minutes when compared to the basal level of glucose recorded. All treated diabetic groups showed a significant decrease in glucose level on the 21st day. The herbal formulation of Hydrastis canadesis Aloe capensis, Echinacea angustifolia and honey exhibited a significant glucose-lowering activity in alloxan-induced diabetic rats.

Diabetes is a chronic disease which characterized by hyperglycemia (elevated or abnormally high blood sugar levels) and other metabolic disturbances, including metabolism of lipids and haemostasis. Caesalpinia pulcherrima has previously showed strong anti-diabetic and hepatoprotective potential. The present research work was to investigate the anti-diabetic activity and hepatoprotective activity Caesalpinia pulcherrima in streptozotocin-induced (STZ) diabetic rats. The dose-dependent effects of 45days oral treatment with methanol extract of plant (200 and 300mg/kg) of CPAE on body weight, blood glucose level, total protein, albumin, liver marker enzymes and carbohydrate metabolizing enzymes were evaluated in STZ-induced diabetic rats. Oral administration methanolic extract of Caesalpinia pulcherrima of showed significant restoration of the body weight and decrease in the blood glucose level, liver marker enzymes (ALT, AST ALP) and carbohydrate metabolizing enzymes were observed in diabetic rats. These results suggest that fruit extract of Caesalpinia pulcherrima has valuable anti-diabetic activity in STZ-induced diabetic rats which is comparable to the standard drug metformin and hence might be of use in the management of diabetes.
