Effect of aqueous and ethanol extracts of Cucurbita maxima seed on fasting blood glucose in alloxan-induced rats

Diabetes is a chronic disorder marked by hyperglycemia due to insulin resistance and insufficient insulin action, or both. Synthetic antidiabetic drugs available on the market are associated with severe effects, necessitating the need for alternative antidiabetic drugs. This investigation aimed to determine the antidiabetic potential and phytochemical profiles of aqueous and ethanol seed extracts of Cucurbita maxima. The seeds of C. maxima were airdried, milled, and extracted using distilled water and ethanol. The antidiabetic effect of the extracts was performed using Wistar rats weighing 160-180 g. Thirty-five rats were assigned to 7 groups: non-diabetic (control), diabetic, glibenclamide-treated, and aqueous or ethanol extract-treated (200 and 400 mg/kg body weight). Alloxan monohydrate was used to induce experimental diabetes. The treatments were orally administered for 28 days. Blood glucose levels and histopathological analysis were performed. The phytochemical screening was conducted utilizing liquid chromatography-mass spectrometry (LC-MS). In diabetic rats, the effects of the two extracts revealed a substantial reduction in levels of fasting blood glucose in a dose-dependent manner, suggesting an antidiabetic effect. The histopathological analysis revealed the restoration of pancreatic β-cells by the extracts. The LC-MS analysis identified phytocompounds in the extracts belonging to classes of flavonoids, phenolic acids, and fatty acids that are associated with antidiabetic effects. Interestingly, the ethanol extract had a better antidiabetic effect compared to the aqueous extract. In conclusion, the aqueous and ethanol extracts of C. maxima seed possess phytocompounds that can be used to develop novel antidiabetic agents with less severe effects.

Combined Antidiabetic and Antidyslipidemic Activity of Ageratum conyzoides and Gynura procumbens in Alloxan-induced Diabetic Rats

Unhealthy lifestyle habits greatly increase the risks of various degenerative illnesses, for example, diabetes mellitus as well as dyslipidemia. Recent studies have shown that the pharmaceutical drugs used for the treatment of these conditions have undesirable side effects. This indicates that it is necessary to find more effective and safe alternative treatment options, particularly in medicinal plants, such as Ageratum conyzoides and Gynura procumbens. Therefore, this research examined the combined antidiabetic and antidyslipidemic activity of Ageratum conyzoides and Gynura procumbens extracts in alloxan-induced diabetic rats. The insulin sensitivity of the test animals was assessed at the beginning of the experiment using the oral glucose tolerance test (OGTT) through the administration of 3 g/kgBW glucose. Pancreatic destruction was induced with the intraperitoneal injection of a single dose of 150 mg/kgBW alloxan, and the rats were treated with ethanol extract for 14 days. High-density lipoprotein cholesterol (HDL-C), Triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) were measured using the enzymatic method. The results showed that the single extracts and their combination exhibited high antidiabetic and antidyslipidemic activity. This was indicated by a substantial reduction in fasting blood sugar, TG, TC, and LDL-C (p<0.05), and an insignificant increase in HDL-C. The activity of the combined extract was similar to the single extracts, but it was not better in decreasing TG levels. Based on these findings, 95% ethanol extract of Ageratum conyzoides, Gynura procumbens, and their combination exhibited high antidiabetic and antidyslipidemic activity in alloxan-induced rats.

Histological Features of Different Organs Before and After Treatment of Diabetes by Using Avocado Extract in Rats

Aim of the study: The present study aimed to study histological features of different organs before and after treatment of diabetes by using avocado extract in rats. Materials and methods: Hot aqueous extraction of avocado was performed. Forty male rats (weighted 140–190g) were used in this study. Following the time of acclimatization, the animals had an overnight fast of 18 hours before being prepped for alloxan monohydrate-induced diabetes. Before and after induction, measurements of the animals' body weights and blood glucose levels were made. However, rats received an IP injection of alloxan 150 mg/kg bw. Following that, the rats' blood glucose levels were tracked every day for 3 weeks to establish a stable levels of blood glucose. The animals were divided into 4 groups: Group 1 got water as a non-induced (negative control) condition. Alloxan-induced rats in Group 2 received water as a positive control. Group 3: Alloxan-induced and aqueous extract-treated animals and Group 4 was only given a 40 g/L dose of the aqueous extract of avocado. Pancreas, livers, as well as kidneys from control, alloxanized, and treated rats were taken at different times, processed and utilized for histological examination after being preserved in 10% formaldehyde till processing and staining. Results: The current results showed a significant difference between different groups especially in G3 at different weeks. However, rats in G2 exhibited depleted islet cells and regions of cell necrosis. The tiny, preserved islet cells (PIL) in diabetic rats treated with extract after 1 week (G3) were an improvement as compared with rats at G2. As the days advanced, more improvements were seen in the pancreatic architecture of the rats treated with extract, including the presence of more noticeable islet cells and exocrine cells. As seen by the intact pancreatic islet in G3, caused the healing of the pancreatic tissue after 3 weeks of treatment by extracts. Alloxanized rats (G2) showed the presence of cell necrosis as well as infiltrations of inflammatory cells. However, as the course of therapy continued, it became clear that the tissue architecture had improved, and more glomeruli were seen as well as fewer inflammatory cells (G3). Livers of rats in (G2) showed visible cell necrosis, when compared to the histology of G1 and G4. After receiving medication, rats in group G3 had compact, healthy liver tissues after three weeks. In conclusion, the pancreas, kidneys, and liver were all protected by the avocado extract and showed enhancement in the histological architecture and glucose levels. KEY WORDS: Diabetes, Avocado, Histology, Rats.

Administration of alloxan and streptozotocin in Sprague Dawley rats and the challenges in producing diabetes model

Alloxan and streptozotocin are the most prominent diabetogenic agents in diabetes research. However, most published reports do not represent the practical importance of their application. The present study evaluated alloxan and streptozotocin with various doses to determine the optimal diabetic model in Sprague Dawley rats. This study also identified the challenges in inducing diabetes using both agents. Every dose of alloxan (120, 150, 180 mg/kg) and streptozotocin (40, 50, 60 mg/kg) was administered through intraperitoneal injection. The results showed that alloxan-induced rats produced the highest mortality at the dose of 180 mg/kg, the highest incidence of diabetes at 150 mg/kg, and the highest induction failure at 120 mg/kg. In streptozotocin-induced rats, the highest mortality was at the dose of 60 mg/kg, the highest incidence of diabetes was at the dose of 50 mg/kg, and the highest diabetes induction failure was at 40 mg/kg. Cases of self-recovery and late diabetes were found in rats that received alloxan. Meanwhile, streptozotocin-induced rats only showed cases of self-recovery, especially at the dose of 40 mg/kg. This study also found differences in blood glucose, body weight, and insulin levels among the groups. This study concluded that induction of 50 mg/kg of streptozotocin resulted in the most ideal diabetic animal model based on low mortality, high induction success rate, and stable hyperglycemia.

Antidiabetic activity of mango peel extract and mangiferin in alloxan-induced diabetic rats

BackgroundIn diabetic animals, there is a significant increase in plasma glucose, serum total cholesterol, triglyceride, and low-density lipoprotein levels, and decreased body weight, liver and muscle glycogen, and high-density lipoprotein. Effective treatment of diabetes mellitus is not yet known, even though the management of diabetes mellitus is considered a global concern. Plants and herbs have played an important role in the healthcare of many societies throughout history. Today’s researchers are investigating the potential for using these nonpharmaceutical approaches to treat and control diabetes, either in conjunction with standard treatments or as an alternative to them. Herbal formulations are favored because to lower cost and fewer side effects compared to other methods for alleviating diabetes and its consequences. In ethnomedicinal practices, different parts of Mangifera indica are used to treatment of diabetes. The present investigation was undertaken to evaluate the antidiabetic activity of an ethanolic extract of Mangifera indica and mangiferin in alloxan-induced diabetic rats. This experiment was conducted in a set of two with four groups of animals namely control (Tc), treatment alloxan (Ta), treatment extract (Tae), and treatment mangiferin (Tam). To develop diabetes, Wistar rats treated with 150 mg/kg b.w. of alloxan monohydrate were injected intraperitoneally. Tae and Tam’s groups received a freshly prepared single dose of extract and mangiferin in distilled water via the oral route. All experimental groups received laboratory pallet feed diet and drinking water ad libitum. Diabetic rats were treated for 21 days with an ethanolic extract of mango peel and pure mangiferin orally daily at rates of 200 mg/kg b.w. and 20 mg/kg b.w.ResultsAn alloxan-induced diabetic rat treated with mango peel extract and mangiferin significantly improved the overhead impact due to diabetes. There was a significant (p < 0.05) body weight loss in the alloxan-induced diabetic rats (Ta), whereas animals given mango peel extract and mangiferin showed a significant increase in body weight from 2 weeks onwards in comparison with control. Alloxan-induced rats (Ta) group have higher blood glucose levels and are significantly different (p < 0.01) from the control group. Mango peel extract and mangiferin significantly reduced the levels of fasting glucose after 21 days of treatment in comparison with diabetic animals. Mango peel extract and mangiferin influence the glycogen synthesis pathway in diabetes groups by increasing glycogen levels in muscle and liver. mango peel extract and mangiferin were found to have a nonsignificant impact on plasma cholesterol and HDL levels compared with the control group. Mango peel extract was found to have a significant difference (p < 0.05) in LDL levels compared with the control group. Mangiferin was found to have a significant difference (p < 0.05) in triglyceride and VLDL levels when compared with the control group. Histopathological examination of the pancreas in rats with type I diabetes caused by alloxan found that therapy with an ethanolic extract of mango peel and mangiferin restored beta cell function as well as rejuvenation of Islets of Langerhans.ConclusionsMango peel extract and mangiferin have antidiabetic, glycogenesis, and hypolipidemic properties when administered to alloxan-induced diabetic rats.Graphical abstract

The Effect of Schleichera oleosa L. on HbA1c Levels in Alloxan-Induced Rats

Diabetes mellitus is a chronic disease that occurs due to the failure of the pancreas to produce sufficient insulin, or the body cannot use the insulin it makes effectively. The HbA1c (glycated hemoglobin) levels show an alteration in blood glucose levels in people with diabetes. As a traditional medicine, the kesambi plant (Schleichera oleosa L.) can improve diabetic people's health due to its secondary compounds, such as alkaloids, flavonoids, tannins, steroids, and phenolic compounds, besides several empirically proven as antiulcer, anticancer, and antimicrobial effects. The study aimed to determine the effect of the ethanol extract of Kesambi leaves on HbA1c levels in alloxan-induced rats. This research used a posttest-only design method, using 18 rats divided into six groups of mice and induced by alloxan 150 mg/kg in intraperitoneal with the division of groups: group I without treatment; group II alloxan + Na CMC; group III alloxan + glibenclamide; groups IV, V, and VI, given alloxan + kesambi leaf extract 200, 400, and 600 mg/kg BW, respectively. All treatments were given orally for 23 days. HbA1c values were measured on day 24 using the Afinion HbA1c. The data obtained were analyzed using the method of comparing the measurement results of each group against the control group. The results showed that the 200, 400, and 600 mg extracts affected HbA1c levels with successive values of 5.47%, 5.37%, and 5.47% compared to the control group, namely 5.10%. This study concluded that giving kesambi leaf ethanol extract can affect HbA1c levels.

Diabetes mellitus (DM) is one of the globally worst killer diseases. In this study, the in vitro and in vivo antidiabetic activity and antioxidant capacity were determined and the phytochemical analyses were carried out on flower extract and sub-extracts of Rhaponticoides iconiensis. The in vitro antidiabetic activity was tested with α-amylase and α-glucosidase enzyme inhibition methods and an in vivo OGTT test in healthy and alloxan-induced rats. Although, the antioxidant activity was investigated with DPPH●, ABTS●+ and FRAP tests, the phytochemical composition analysis was carried out by LC-MS/MS. The highest α-glucosidase and α-amylase activity even from positive control acarbose were found in the ethyl acetate sub-extract of R. iconiensis (IC50 = 11.737 ± 0.823 µg/mL and 84.247 ± 0.721 µg/mL, respectively). This sub-extract also was active according to the results of in vivo tests. Moreover, the highest antioxidant activity on DPPH● (IC50 = 0.126 ± 0.002 mg/mL), FRAP (at a concentration of 1 mg/mL equivalent to 3112.052 ± 2.023 mmol Fe2+) and ABTS+● (at a concentration of 0.5 mg/mL equivalent to 0.608 ± 0.005 µM Trolox) tests. In addition, LC-MS/MS analyses of the active sub-extract revealed mainly the presence of patuletin, patuletin 3,7-diglucoside, naringin and 3,4-dicaffeoylquinic acid detected in the active sub-extract. In silico molecular docking and dynamics simulations studies were performed on these compounds with α-amylase and α-glucosidase enzymes for protein-ligand interactions and stability.

Antidiabetic and antihyperlipidemic have a very close relationship for Mellitus Diabetics. In previous research, Ekor Naga leaves ( Rhaphidophora pinnata (L.f) Schott) had an antihyperglycemic effect. The effect was obtained from the presence of secondary metabolites, namely alkaloids, flavonoids, tannins, saponins, and steroids. This research is expected to be a further test of the antidiabetic and antihyperlipidemic effects of alloxan-induced male white rats. This research used an experimental method. The treatment group was divided into four groups, namely negative control (Na CMC 0,5%), positive control (10 mg/kg BW of glibenclamide), group one (250 mg/kg BW of Ekor Naga leaves extract), and group two (500 mg/kg BW of Ekor Naga leaves extract). Data were taken from blood sugar levels on the days 0 th , 7 th , 10 th , and 14 th . Total cholesterol, triglyceride, LDL, and HDL levels were observed on the 14 th day. Results were analyzed by one-way ANOVA test. The followed by Duncan’s test. The result of ethanol extract from Ekor Naga leaves showed antidiabetic and antihyperlipidemic activity in alloxan-induced rats, which had a statistically significant difference relative the negative control (p&lt;0,05) decreased the levels of blood glucose, total cholesterol, HDL, LDL, triglycerides. Where the best group is two (500 mg/kg BW of Extract) and followed by group one (250 mg/kg BW of Extract). We concluded that Ekor Naga leaves extract provides activity in the treatment option for patients with diabetes and hyperlipidemia.

The Hypolipidemic Effect of Mountain Papaya and Bitter Melon Fruit Ethanolic Extract in Diabetic Rats

Traditional medicine has been developed rapidly throughout the world to treat hyperlipidemia. However, the use of a single compound in hyperlipidemia treatment usually have low efficacy. Therefore, a combination of ingredients is bound to have more synergistic impact in therapy. This research aimed to examine the hypolipidemic potential of mountain papaya (MPE) and bitter melon fruit ethanolic extract (BME) in alloxan-induced rats. Forty rats divided into eight groups were used in this study. Groups are divided into normal control, negative control, positive control, as well as MPE and BME groups which divided into single doses and three combination doses. Induction of 150 mg/kg alloxan intraperitoneally were performed to generate a model of diabetes and hyperlipidemia. The treatment was carried out for four weeks of the experiment. The single and combination doses of both extracts sufficiently exhibited hypolipidemic activity (p &lt; 0.05). The levels of lipid profiles total such as cholesterol, triacylglycerides, low-density lipoprotein, high-density lipoprotein, and very high-density lipoprotein were decreased after MPE and BME administration (p &lt; 0.05). The combination of MPE and BME also has hypolipidemic action equivalent to simvastatin. The single and combined doses of mountain papaya, as well as bitter melon fruit ethanolic extracts, have the potential to improve the biochemical (lipid profile) modifications of alloxan-induced.

EMZSB has elucidated a considerable in vitro free radical scavenging potential by DPPH and H2O2 assays when compared with absolute ethanolic extract of Manilkara zapota (L) P. Royen stem bark (AEMZSB), while ascorbic acid was taken as the standard. Further, EMZSB demonstrated high in vitro α-glucosidase enzyme inhibition potential (IC50 = 119.79 ± 1.52 µg/mL) than AEMZSB (IC50 = 129.92 ± 2.29 µg/mL) with a significant difference (p < 0.01), when acarbose was taken as reference inhibitor (IC50 = 86.43 ± 1.26 µg/mL). During acute toxicity studies EMZSB was safe up to 2000 mg kg−1 doses while, found causing moribund status followed by mortality in mice at 3000 mg kg−1 and above doses. A preliminary antidiabetic study with EMZSB-250 mg kg−1 in normal rats showed no sign of hypoglycemia; however, a dose-dependent antihyperglycemic effects were observed in oral glucose tolerance test in glucose-loaded rats. In vivo assessment with EMZSB-250 mg kg−1 in alloxan-induced rats demonstrated significant blood glucose-lowering effects with perfection in serum lipid profile, body weight enhancement, cardiovascular risk indices, nephroprotective effects, augmentation in liver glycogen content, and histopathological evidence of normal architecture of kidneys with no marks for nephritis.ConclusionsEMZSB-250 showed significant antidiabetic effects and ameliorated diabetic complications by improving glycemic control and accompanying biochemical alteration.

Evaluating the effect of Ginger Powder on Bilirubin, Creatinine, Urea and Uric Acid on Experimental Diabetic Wistar Rats in Randomized Control Trial

Today the world is dealing with rapidly increasing cases of diabetes mellitus especially type 2 diabetes which creates insulin resistance. Scientists are working with different nutraceuticals to cure this disease. Objective: Ginger plays an important role in different ailments such as cardiovascular diseases, hypertension, cancers, gastrointestinal functions, and diabetes mellitus. In the present study, ginger powder was analyzed for its anti-diabetic effect. The ginger powder was analyzed for its proximate composition. Methods: The bio-efficacy study was done on Alloxan-induced Wistar rats by feeding them ginger powder at three levels i.e. 1%, 3%, and 5% ginger powder for a period of 4 weeks. There were 4 groups (one was control and the other three getting different percentages of ginger powder), each containing 5 rats. The blood samples were collected at 0 days, 15th day, and 28th day. Blood sugar and insulin levels were measured. The data thus obtained was statistically analyzed to find out the level of significance. Results showed that glucose levels significantly decreased along with a significant increase in insulin levels. This research design concludes that ginger powder has positive effects in lowering blood sugar levels. Hence, the usage of ginger powder and ginger tea should be increased in diabetic patients to reduce hyperglycemia in diabetic patients and overcome high BSL levels in pre-diabetics. Conclusions: Results of this study concluded that in ginger powder 1.7 STD magnesium and 0.3 STD chromium are present. Moreover, this research study also declared that mean values of RFTs i.e. bilirubin, creatinine, urea, uric acid had a significant change in the G4 group as mean results of 0.591±0.032, 0.814±0.058, 0.814±0.058, 0.9508±0.051 respectively.
