Introduction: There is a need to develop diabetic animal model, to have a better understanding of the complications of diabetes mellitus. The dose of Streptozotocin (STZ) to induce diabetes mellitus in animals is important as it may lead to inadequate induction of diabetes or mortality. Intravenous injection of STZ in adult Wistar rats, leads to the degeneration in Langerhans islet β-cells and induces experimental diabetes mellitus in 3-5 days. Aim: To optimise the dose of STZ to create a diabetic animal model with sustained hyperglycaemia and to compare the changes in body weight, serum glucose and C-peptide levels between non diabetic and diabetic rats. Materials and Methods: This experimental animal study was conducted at animal house, Pal amur Bioscience Pvt., Ltd. The sample size included 30 albino Wistar rats divided into five groups T0, T1, T2, T3 and T4 with six rats in each group (three males and three females). Group T0 was the control, while STZ at different concentrations were administered intraperitoneally in group T1, T2, T3 and T4, respectively. Blood samples were drawn from retro-orbital plexus of animals and blood glucose, C-peptide levels along with the body weight was checked on 7th, 14th, 21st and 28th day. The F statistics, one-way Analysis of variance (ANOVA) was used to compare the different groups. Denny’s test was used to compare the control group versus different test groups. Results: When compared with the control group T0 on 7th, 14th, 21st and 28th day, the test group T1 had no variation in the body weight. On the other hand groups T2, T3 and T4 had variations in the body weights. Initially there was increase in the weight, later here was a gradual decrease in the body weight when compared to the control group. Hyperglycaemic profile (blood glucose level >120 mg/dL) was achieved in group T1, T2, T3 and T4 after 7 days. High mortality rate was observed in group T4 followed by group T3. Group T2 had persistent hyperglycaemia while group T1 had reversible hyperglycaemic profile. The C-peptide levels were gradually decreased in the test groups and it was statistically significant (p-value <0.0001). Conclusion: Intraperitoneal dose of STZ of 55 mg/kg created diabetic animal model with persistent hyperglycaemia. However, dose above increased the mortality rate and below failed to create diabetic animal model.

The aim of this study was to evaluate the influence of ligature-induced periodontal disease in pregnant rats on their newborn's health parameters. Twenty-four female adult Wistar rats were divided into two groups: the control group (G1) and the group that was submitted to dental ligatures around second upper molars (G2). After the four week period of development of periodontitis, the female animals were mated with male adult Wistar rats. There were no differences in the body weight of females between the two groups during mating and pregnancy. No differences were observed among the groups in relation to the viable newborn index. However, there were differences in newborn birth weight, explained by the diverse size of the litters. In this study, ligature-induced periodontal disease did not promote changes during pregnancy that resulted in low birth weight in newborn Wistar rats.

Accumulating evidences have reinforced the use of medicinal plants in the treatment of various ailments as a result of negative side effects associated with conventional drugs. Plant components such as phenols and flavonoids with antioxidant potential have confirmed protective roles against oxidative stress-induced degenerative diseases like diabetes mellitus (DM). The current study was carried out to investigate the effect of seed pod ethanol extract from Copaifera salikounda (SPEECS) in alloxan-induced diabetic rats. SPEECS was obtained by maceration of seed pod powder in absolute ethanol for 72 h, filtered, concentrated and dried in-vacuo. Gas chromatography-mass spectrometry (GC–MS) technique was used to quantitatively elucidate the chemical constituents of SPEECS. Twenty-four male albino rats were randomly allocated into four groups (n=6): normal control, DM control, DM + 200 mg/kg SPEECS and DM + 400 mg/kg SPEECS groups. DM was induced in the Wistar albino rats through intraperitoneal injection of 200 mg/kg body weight of alloxan. After 14 days of treatment, the body weight changes and the fasting blood glucose level were determined in the different groups. Also, serum biochemical parameters such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), albumin (ALB), total protein (TP), malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) were estimated. The GC-MS results confirm nine bioactive compounds with 9-octadecenoic acid (55.75%) being most abundant. SPEECS (200 and 400 mg/kg) administration significantly (P 0.05) caused gain in weight, decreased fasting blood glucose and reversed the elevated liver function enzymes (ALT, AST, ALP) while total TP and ALB were markedly elevated relative to DM control group. Furthermore, SPEECS attenuated the activities of SOD and CAT while the level of MDA was significantly (P 0.05) decreased in dose dependent manner in comparison to the DM control. This study indicated that SPEECS can alleviate hyperglyceamia of DM. Key words: Copaifera salikounda; oxidative stress; medicinal plants; diabetes mellitus; phytochemicals; orthodox ANTIDIABETIČNI UČINEK EKSTRAKTA ETANOLA Copaifera salikounda (HECKEL) NA SLADKORNO BOLEZEN, SPROŽENO Z ALLOXAN-om, PRI PODGANAHIzvleček: Obstaja vedno več dokazov, ki poudarjajo uporabnost zdravilnih rastlin pri zdravljenju različnih bolezni, tudi zaradi različnih negativnih stranskih učinkov, povezanih s konvencionalnimi zdravili. Rastlinske sestavine kot so fenoli in flavonoidi z antioksidativnim potencialom, imajo po nekaterih raziskavah zaščitno vlogo pred degenerativnimi boleznimi, ki jih povzroča oksidativni stres, kot je sladkorna bolezen diabetes mellitus (DM). Študija je bila izvedena z namenom raziskovanja učinka etanolnega semenskega ekstrakta iz rastline Copaifera salikounda (SPEECS) pri podganah s sladkorno boleznijo, ki jo je povzročil alloxan. SPEECS je bil pridobljen z maceracijo praška semen v prahu v absolutnem etanolu 72 ur ter nadaljnjo filtracijo, koncentracijo in sušenjem v vakuumu. Za kvantitativno ugotavljanje kemijskih sestavin SPEECS je bila uporabljena tehnika plinske kromatografije in masne spektrometrije (GC-MS). Štiriindvajset samcev podgan Wistar je bilo naključno razporejenih v štiri skupine (n=6): normalna kontrola, kontrola DM, DM + 200 mg/kg SPEECS in DM + 400 mg/kg SPEECS. DM je bil pri podganah sprožen z intraperitonealno injekcijo 200 mg/kg telesne mase alloxana. Po 14 dneh zdravljenja so bile pri različnih skupinah določene spremembe telesne teže in nivo glukoze v krvi (na tešče). Poleg tega so avtorji raziskave izmerili še nekatere serumske biokemične parametre kot so ravni alaninske aminotransferaze (ALT), aspartatne aminotransferaze (AST), alkalne fosfataze (ALP), albumina (ALB), skupnih proteinov (TP), malondialdehida (MDA), superoksiddismutaze (SOD) in katalaze (CAT). Rezultati GC-MS so v izvlečku SPEECS pokazali devet bioaktivnih spojin, v katerih je največ 9-oktadecenojske kisline (55,75%). SPEECS (200 in 400 mg/kg) je povzročil znatno (P 0,05) povečanje telesne mase, znižanje glukoze v krvi na tešče in znižal raven encimov pokazateljev jetrne funkcije (ALT, AST, ALP), medtem ko je bila raven TP in ALB pri podganah, ki so prejemale SPEECS izrazito povišana v primerjavi z DM kontrolno skupino. Zdravljenje s  SPEECS je tudi oslabilo aktivnosti SOD in CAT, medtem ko se je raven MDA znatno zmanjšala (P 0,05) v primerjavi s kontrolno skupino DM. Ta študija je pokazala, da lahko SPEECS ublaži hiperglikemijo pri sladkorni bolezni pri podganah.Ključne besede: Copaifera salikounda; oksidativni stres; zdravilne rastline; sladkorna bolezen; fitokemikalije; ortodoksni

Aim. To compare the clinical course of diabetes mellitus induced by alloxan using classic and modified technique. Methods. Experiments were carried out on mature white mongrel rats, which were divided into two groups: the first group (25 rats) was administered a 200 mg/kg single dose of alloxan (classic model), the second group (25 rats) was administered 150 mg/kg of alloxan at the first day, 100 mg/kg of alloxan at the second day and 100 mg/kg of alloxan at the fourth day. 25 intact rats were examined as a control group. The animals were withdrawn from the experiment by decapitation on the 10th and 21st day, blood and tissue samples were taken for the laboratory testing. The animals’ status (mortality, grooming behavior, body weight, food and water intake) were measured by visual examination. The levels of glucose and lipids were assessed using enzyme colorimetric detection («Human» laboratory kits, Germany, FP-901 analyzer), insulin and C-peptide levels were examined by enzyme-linked immunosorbent assay («Chemwell» analyzer, «DEMENITECKILL-WELLSEE» laboratory kits, Germany); levels of diene conjugates and malonic dialdehyde - using the photocolorimetry based on the colored thiobarbituric acid products. Results. In the first group, the mortality reached 68%, mean weight loss - 41.2%. Blood glucose level at the 10th and 21st days was higher by 370.7 и 146.2% respectively compared to intact animals. Insulin level decreased by 95.8 and 83.7%, C-peptide level - by 96 and 83.7%. In the second group, mortality was 32%, mean body weight loss - 36.5%, blood glucose level at the 10th and 21st days elevated by 364.5 and 151.5%, insulin level decreased by 96.1 and 82.9%, C-peptide level - by 96.0 and 83.7% respectively. A moderate hyperlipidemia was observed in both groups with increased levels of cholesterol, triglycerides, low and very-low density lipoproteids, free fatty acids and decreased levels of high density lipoproteids. The concentration of diene conjugates and malonic dialdehyde increased rapidly to a variable degree depending on the tissue anti-oxidative activity. Conclusion. When diabetes mellitus is modeled by the use of alloxan, an acute form of alloxan-induced diabetes is observed on the 10th day, a chronic form - on the 21st day in both groups. The modified model of alloxan-induced diabetes showed 36% less mortality rate compared to the classic model.

Objective: To determine the anti-hyperglycemic effects of interleukin-1 inhibitor (diacerein) in alloxan induced diabetic albino wistar rats. This experimental study was performed at the Department of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University, Tando Jam within 6 months from April 2016 to September 2016. Total of 160 adult Albino Wistar Rats having an average of 200 to 300 grams body weights were selected. Animals were categorized into 4 groups as; Group A (n=15): Control rats – receive 0.9% normal saline as placebo Experimental Groups Group B (n=15): Experimental Control (Diabetic rats) - Alloxan50 mg/kg body weight intraperitoneal. Group C (n=15): Diabetic rats + Diacerein (30 mg/kg/day) orally daily. Group D (n=15): Diabetic rats + Diacerein (50 mg/kg/day) orally daily. Animals were kept and treated as per the NIH Guideline for Use and Care of Laboratory Animals. Diabetes mellitus was induced via a single intraperitoneal injection of 50 milligram/kg alloxan monohydrated dissolved in aseptic 0.9% saline. After 72 hours, blood specimens were taken from the caudal vein of the rats and glucose level>200 mg/dL was taken as diabetes. Experimental rats were given diacerein approximately 30 and 50 mg orally for 6 weeks. At the completion of experiment the body weight was measured of each animal by electronic measuring balance and blood sample was taken from each animal of all groups to assess the blood glucose level and HbA1c level. Data were recorded via self-made proforma and analysis was done by using SPSS version 20. Results: Average body weight of Diabetic control (Group B) was 193.33±22.50 grams, which was lower in contrast to Diacerein treated group C 202.47±25.70 grams and significantly lower as compared to Diacerein treated group D as  212.6±23.43 grams. A significant increase in blood glucose levels 182.07±10.63 mg/dl was noted in the Diabetic control (Group B) compared to Diacerein treated group C (110.13± 8.54 mg/dl) and group D (85.87±8.41 mg/dl) (P=0.001). HbA1c was markedly raised in the Group B- diabetic controls, while diacerein treated diabetic rats (groups C and D) showed a significant decrease in HbA1c (P=0.001). Conclusion: It was concluded that Diacerein achieves the Euglycemic state by reducing the levels of blood glucose and glycated hemoglobin (HbA1c) in Alloxan-Induced diabetes mellitus in Wistar Albino Rats.

Sugar-sweetened beverages (SSBs) are known to cause metabolic pathologies increasing the risk for Type 2 diabetes mellitus and cardiovascular disorders. We aimed to determine the effects of chronic sugar intake on lipogenesis and glucose metabolism in mice and study if bitter melon extract (BME) can reverse this effect. BME was prepared using 50% ethanol as solvent, biochemical assays for the estimation of phenolic compounds, antioxidant, and anti-inflammatory activity was performed. Male Swiss albino mice were divided into seven groups (n=6): Control (group-1), Glucose (group-2), Glucose+BME (group-3), Sucrose (group-4), Sucrose+BME (group-5), Fructose (group-6), Fructose+BME (group-7). Each group was induced with 30% wt/vol of respective sugars for 8 weeks, and BME was supplemented (300 mg/kg body weight) to group-3, 5, and 7 along with sugars after 4 weeks of induction. Blood glucose and body weight measurements were performed every week for 8 weeks. Animals were sacrificed and retroperitoneal adipose tissue (RPAT) was collected along with blood for lipid profile estimation. RPAT was stained with hematoxylin & eosin and examined under the microscope for adipocyte cell count/size. Group-3, 5, and 7 presented a significant decrease in the body weight at 8th week when compared to their 4th-week bodyweight, a significant drop in blood glucose and all the lipid profile parameters when compared to their respective control groups, and group-3 and 5 presented a significant reduction in the size of the adipocyte upon treatment with BME. Due to the presence of high phenolic acids, antioxidants, and anti-inflammatory property BME has various health benefits and the potential to treat SSB-induced metabolic disorders.

Background: To understand severity and complications of diabetes mellitus and to analyze effects of drugs, it is necessary to create diabetic animal model. There are different doses of streptozotocin to induce diabetes mellitus in rats that may be associated with mortality or may be insufficient for induction of DM. The objective of our study was to optimize the dose of streptozotocin to create a diabetic animal model with sustained hyperglycemia and to document the toxic dose at which there may be high mortality rate. Methods: This experimental animal study was conducted at animal house, faculty of pharmacy Ziauddin University Karachi in April 2019. The sample size included 30 albino wistar rats divided into five Groups A, B, C, D and E “with 6 rats each group”. Group A was the control, while streptozotocin at different concentrations was administered intraperitoneally in Group B, C, D and E respectively. Blood sample was drawn from lateral tail vein of animals and hyperglycemic profile was checked on 2nd, 4th, 6th, 8th and 10th day. Results: When compared to control Group A, hyperglycemic profile (blood glucose level >180) was achieved in Group B, C, D and E after 48 hours. High mortality rate was observed in Group E followed by Group D. Group C had persistent hyperglycemia while Group B had reversible hyperglycemic profile. Conclusion: Intraperitoneal dose of streptozotocin 60 mg/kg created diabetic animal model with persistent hyperglycemia. However, dose above increased the mortality rate and below failed to create diabetic animal model.

Abstract Aim Onion is one of the commonly cultivated and consumed vegetables rich in nutrients and phytochemicals. Various nutraceuticals are found in the outer fleshy layers and dry peel of onion which usually is treated as a common biowaste. Diabetes mellitus is a leading non communicable disease causing hyperglycemia and increased production of free radicals that potentially disrupts antioxidant enzymatic activity. Considering global consumption of wheat, the present study was designed to evaluate the anti-hyperglycemic and antioxidant effects of wheat bread supplemented with onion peel extract (OPE) or onion powder (OP) on diabetic rats. Methods In this study, ethanolic extract of onion peel and onion bulb were prepared separately. Male Sprague Dawley rats were divided into 6 groups (n = 7). Different regimens of supplemented wheat bread (OPE (1% and 3%) and OP (5% and 7%)) were given to diabetic rats for eight weeks, plain bread was used as the control. Blood glucose level, body weight and activities of SOD, CAT, GPx, GR, GSH and MDA in the liver and kidney tissues were evaluated. Statistical analysis was performed using SPSS Version (25) and Dunnett’s multiple comparison test. Results Bread supplemented with 1% and 3% onion peel extract and 7% onion powder significantly reduced blood glucose levels and MDA in the treated rats compared with the control group diabetic rats. Body weight of diabetic rats was reduced for control group, while onion supplemented diet improved the body weight of treated rats. Onion supplementation also brought significant improvement in antioxidant enzyme activities among the treated diabetic rats. Conclusion These findings suggested that onion supplementation is effective in lowering blood glucose and could potentially aid in protecting organs from oxidative stress.
