Abstract Introduction Stasis zone is the encircling area of the coagulation zone which is a critical area determining the depth and width of the necrosis in burn patients. In our study we aim to salvage the stasis zone by injecting adipose derived stromal vascular fraction (ADSVF). Methods Intraperitoneal Streptozotocin was administered for the induction of diabetes mellitus (DM) and the development of DM was confirmed by the measurement of blood glucose levels in the blood samples with blood glucometer weekly 48 hours after injection. Rats with blood glucose levels above 200 mg/dl were accepted as diabetic. The diabetic animals were followed for 4 weeks before the intervention. Thermal injury was applied on dorsum of diabetic Sprague – Dawley rats (n=20) according to the previously described ‘‘comb burn’’ model. After the burn injury (30 minutes) on Sprague - Dawley rats; rat dorsum was separated into 2 equal parts consisting of 4 burn zones (3 stasis zone) on each pair. ADSVF cells harvested from inguinal fat pads of diabetic Sprague - Dawley rats (n=5) were injected on the right side while same amount of phosphate buffered saline (PBS) injected on the left side of the same animal. One week later, average vital tissue on the statis zone was determined by macroscopy, angiography and microscopy. Vascular density, inflammatory cell density and gradient of fibrosis were determined via immunohistochemical assay. Results Macroscopic stasis zone tissue survivability percentage (32 ± 3.28 %, 57 ± 4.28 %), average number of vessels (10.28 ± 1.28, 19.43 ± 1.72), capillary count (15.67 ± 1.97, 25.35 ± 2.15) and vascular density (1.55 ± 0.38, 2.14 ± 0.45) were higher on ADSVF side. Fibrosis gradient (1.87 ± 0.51, 1.50 ± 0.43) and inflammatory cell density (1.33 ± 0.40, 1.20 ± 0.32) were higher on the PBS side. Conclusions Macroscopic and microscopic findings determined that ADSVF has a statistically significant benefit for salvaging stasis zone on acute burn injuries in DM.

Background: Several previous studies suggest that SPX plays a role in appetite control and body weight and blood glucose regulation. The aim of this study to determine SPX levels in healthy pregnancies and in gestational diabetes (GDM) and to investigate the association of SPX levels with weight gain and lipid and glucose metabolism in subjects with and without GDM.Methods: A total of 44 women with GDM and 44 women without GDM were randomly enrolled who applied for GDM screening during the 24-28th week of pregnancy. Demographics, blood glucose and lipid profiles and Spexin levels were compared between groups.Results: The mean age, BMI, and weight gain during pregnancy were higher in the GDM group. The LDL cholesterol, Hba1c, SPX and glucose levels in response to OGTT were higher in the GDM group. The SPX levels were correlated with Hba1c and blood glucose levels after OGTT, and were not correlated with the age, BMI, weight gain during pregnancy, lipid parameters, and fasting blood glucose levels in the whole study population.Conclusions: SPX levels were higher in the GDM group compared with non-GDM group and SPX levels were correlated with HbA1c levels and post-OGTT glucose levels but not with fasting glucose levels.

The association of liver and muscle glycogen deposits with serum insulin levels, β-cells pancreas, and fasting blood glucose (FBG) of streptozotocin (STZ)-induced hyperglycemic rats receiving Torbangun leaves extract (TE) investigated. The intervention performed on 25 8-week-old Sprague-Dawley rats divided into four groups. Seven rats separated as a normal group (N), and other rats injected with streptozotocin (STZ). Confirmation of hyperglycemic was characterized by fasting blood glucose >126 mg/dl. Treatment group which is NG (hyperglycemic rats); N (normal rats); H-IM (62.5 mg/kg BW metformin); and H-IT (620 mg/kg BW TE) for 14 days. This study revealed that TE significantly decreased FBG levels, increased insulin production, and the amount of liver glycogen deposits (a=0.01). However, the intervention did not significantly increase the amount of muscle glycogen deposits. TE administration improves β-cells, increases the liver and muscle glycogen deposits. TE was shown to have antihyperglycemic activity by improving the β-cell, increasing blood serum insulin levels, decreasing blood glucose levels, and increasing the liver glycogen deposits.

Hypoglycaemic Activity

Desmodium canum (Strong back) commonly consumed as a tea or tonic is believed to possess hypoglycaemic activity. This paper sets out to isolate potential hypoglycaemic compounds present within the plant and investigate their synergistic effects on blood glucose levels in euglycaemic Sprague Dawley rats. The milled plant was sequentially extracted using hexane, ethyl acetate and methanol. The ethyl acetate extract was subjected to column chromatography yielding seven major fractions and were subsequently bioassayed using the Oral Glucose Tolerance Test (OGTT). Further chromatographic separation and analysis using Gas Chromatography–Mass Spectroscopy and Fourier Transform Infrared Spectroscopy enabled the identification of two hypoglycaemic compounds, oleic acid (OA) and succinic acid (SA). These were bioassayed individually and as a cocktail to determine the synergistic effects using OGTT. Intravenous administration of these compounds individually indicated both are very potent in retarding blood glucose levels. However, the most significant activity was observed on synergistic administration. The cocktail (1 : 1) displayed significant hypoglycaemic activity throughout the entire study. It also significantly differed from OA at the 120 min interval (3.43 ± 0.22 mmol/L vs. 4.98 ± 0.19 mmol/L, resp., p = 4.29 × 10 − 7 ) and significantly differed from SA at 30 min (3.95 ± 0.43 mmol/L vs. 5.17 ± 0.32 mmol/L, resp., p = 0.003 ), 90 min (4.35 ± 0.36 mmol/L vs. 5.49 ± 0.69 mmol/L, resp., p = 0.04 ), and 120 min intervals (3.43 ± 0.22 mmol/L vs. 4.94 ± 0.31, resp., p = 1.54 × 10 − 5 ). Oral administration of the cocktail showed comparable potency to that of metformin ( p > 0.05 ) throughout the OGTT curve. The synergistic effects of the naturally isolated compounds yielded higher potency levels than individual administration and when administered orally, the hypoglycaemic effect was similar to that of metformin. This may assist in paving a way to attempt a novel method in approaching antidiabetic therapy.

Objective: Azadirachta indica is a treasure of multiple pharmacological properties and presently leaves of this plant have been explored to evaluate the neuroprotective potential in diabetic rats.Methods: Male Sprague-Dawley rats were injected with single intra peritoneal dose of streptozotocin (60mg/ Kg body weight (BW.) to develop animal model of diabetes. Post twenty one days of streptozotocin induction, animals were treated with aqueous Azadirachta indica Leaf Extract (ALE, 600mg/Kg BW.) for seven consecutive days. Followed this, all animals were evaluated for the levels of blood glucose, lipid peroxidation (LPO), C Reactive Proteins (CRP), pro oxidant biomarkers and histological changes.Results: Streptozotocin treated rats exhibited elevated levels of blood glucose, LPO, CRP and altered pro oxidant biomarkers in comparison to control rats. Additionally, histological alterations/damage was evidenced as fragmentation, vacuolization, inflammation etc. However, ALE treatment to these rats significantly decreased blood glucose levels, LPO, CRP levels and restored pro-oxidants status. Light microscopic and ultra microscopic analysis also indicated less damage, tissue architectural changes in comparison to untreated diabetic rats. Further decrease in hyperalgesia and inflammation levels; along with protective and restorative changes following ALE treatment suggested the neuroprotective potential of Azadirachta indica leaves in diabetic rats.Conclusion: The oral administration of ALE to streptozotocin induced diabetic animals resulted in neuro-protection against degenerative oxidative stress associated with metabolic and histopathological damage in the brain.Key words:  Azadirachta indica, Antioxidants, Hyperalgesia, Neuroprotection

Functional Drink

Functional drinks containing the leaves of Java tea has been shown to offer many health functionalities, particularly to lower blood glucose levels, due to its bioactive compounds. Nanoencapsulation technology was reported being able to protect these bioactive compounds and also enhance their bioavailability. This study examined the use of nanoencapsulation techniques to improve the bioavailability of Java tea-based functional effervescent drink and enhance its antihyperglycemic activity. Three versions were prepared in this study: ready to drink (RTD) as the control, microencapsulated, and nanoencapsulated. They were all measured for their total phenolic content (TPC) before being tested for their antihyperglycemic activity. The TPC of RTD, microencapsulated, and nanoencapsulated Java tea-based functional drinks (JTFD) were 998,425, 735,433, and 663,517 ppm, respectively. The antihyperglycemic activities were evaluated by feeding each beverage to streptozotocin-induced diabetic Sprague Dawley rats for fourteen days. Nanoencapsulated JTFD was found to be more superior than the other two formulations to decrease the blood glucose level (7.98%), maintain the feed intake, body weight, improve the viability of Langerhans and beta-cells by 49.09%, 32.50%, respectively.

Continuous subcutaneous administration of leptin normalizes blood glucose levels in rodent models of Type 1 and Type 2 diabetes independent of changes in food intake, body weight, and plasma insulin. We tested whether an acute intravenous leptin infusion changed blood glucose in normal and diet-induced leptin-resistant rats to determine whether this measure could be used as a marker of leptin sensitivity. Leptin-responsive chow-fed rats and diet-induced leptin-resistant male Sprague-Dawley rats were fitted with thoracic jugular vein catheters. Four days after surgery, conscious rats were infused intravenously with either saline for 32 min, low-dose (LD) leptin (1.9 μg·kg−1·min−1) followed by high-dose (HD) leptin (3.8 μg·kg−1·min−1) for 16 min each, or only HD leptin for 16 min. There was no change in blood glucose after an acute intravenous infusion of either LD leptin or HD leptin alone for 16 min. An intravenous infusion of LD followed by HD leptin for 16 min each significantly decreased serum glucose in leptin-responsive rats but not in leptin-resistant rats. Leptin infusions increased serum leptin in all rat groups but had no effect on plasma glucagon or 12-h weight gain and energy intake in any group of rats. These results show that leptin has an acute glucose-lowering effect that reflects the leptin responsiveness of the rat. This effect is consistent across controls and different leptin-resistant rat models, and the acute nonlethal test provides a novel method of testing leptin responsiveness in rats.
