Antidiabetic Effects

Diabetes mellitus (DM) is a serious worldwide health threat since the number of people with DM is forecasted to grow annually. Thus, effective and affordable treatment is urgently needed. Our previous studies used n-hexane and hydroethanolic root extracts of Ruellia tuberosa L. which significantly affected diabetic rats. In this study, aqueous R. tuberosa L. root extracts were used as treatments for the diabetic rat model and their effects were evaluated. Diabetes was generated by the administration of streptozotocin (STZ) at 20 mg/kg within 5 sequential days. Male Wistar rats were orally treated with the extracts and standard drug (metformin 200 mg/kg) and vehicle every day for 4 weeks. Hypoglycemic effects were assessed for normal, diabetic control, standard, and extract-treated groups. Histopathology was also carried out for the pancreatic, hepatic, and kidney tissues. The progression of diabetes was considerably diminished after extract treatment. In treated rats, the highest dose of extract induced a decline in blood glucose and serum malondialdehyde (MDA) levels at 25% and 35%, respectively. Furthermore, aqueous extract of R. tuberosa L. treatment decreased MDA levels in the pancreas by 12%. Histologic examination of the organ tissues of diabetic rats showed deteriorating alterations. After treatment, histopathological damages to the tissues and cells were reversed. The results of the experiments recommend that aqueous extract of R. tuberosa L. has antidiabetic effects on STZ-induced diabetic rats; nevertheless, a higher dose of the aqueous extracts is needed to achieve more significant results.

Diabetic Rat Model

Diabetes mellitus is the most common endocrine disorder that impairs glucose homeostasis resulting in severe diabetic complications including retinopathy, angiopathy, nephropathy, and neuropathy causing neurological disorders due to perturbation in utilization of glucose. Hypoglycemic activity was detected in aqueous extract of Passiflora ligularis, a traditionally used medicinal plant, using streptozotocin (STZ, 30 mg/kg body weight) induced diabetic rat model. Oral administration of aqueous extract of Passiflora ligularis to diabetic rats for 30 days resulted in a decrease in blood glucose. The diabetic rats had decreased levels of serum total protein, albumin, globulin, and albumin/globulin ratio as compared to control rats. In addition, the activities of hepatic and renal markers were significantly elevated in diabetic rats as compared to control rats. Treatment with aqueous fruit extract of P. ligularis and glibenclamide reversed these parameters to near normal. Extract at a dose of 400 mg/kg given orally for 30 days showed significant elevation in enzymatic (SOD, catalase, and Gpx) and nonenzymatic antioxidants (vitamin C, vitamin E, and reduced glutathione). Plant extract treated groups showed significant decrease in lipid peroxidation (LPO). Aqueous extract of Passiflora ligularis fruit can decrease the blood glucose and reduce the oxidative stress by removing free radicals in diabetes.

Objective: The present study was aimed to investigate the antidiabetic activity of ethanolic and aqueous extract of Zanthoxylum ovalifolium on alloxan induced diabetic rat model in rats. Methods: The leaves of Zanthoxylum ovalifolium were evaluated for antidiabetic activity by using alloxan induced diabetic model in diabetic rats. Diabetes was induced by single intraperitoneal injection of alloxan (100 mg/kg) and rats were treated orally with test extracts, standard drug (glibenclamide 5 mg/kg) and vehicle for 21 d. The hypoglycemic effects and lipid profile of diabetic rats were assessed using diagnostic kits. Finally, histopathological studies were carried out for pancreas. Results: The acute toxicity studies revealed at the dose of 2000 mg/kg (b. w) of Zanthoxylum ovalifolium for ethanol and aqueous extract were found to be safe. A significant reduction (p<0.001) in blood glucose was observed in diabetic rats treated with different doses of extracts compared to untreated diabetic rats. The drug possesses a good hyperlipidemic effect by normalizing the lipid parameters. This was evidenced by histopathological studies; both glibenclamide and 400 mg/kg of Ethanolic extract does appear to be regulated diabetes at the cellular level, resulting in the restoration of near normal architecture pancreatic islet of langerhans. Conclusion: It can be concluded from our research findings that ethanolic and aqueous extract of Zanthoxylum ovalifoliumat high dose (400 mg/kg) exhibited significant antihyperglycemic activity than extract at low dose (200 mg/kg) in alloxan induced diabetic rats. These extracts also showed improvement in parameters like lipid profile as well as regeneration β-cells in the pancreas and so might be of value in diabetes treatment.

Choline (Ch) is an essential molecule of substantial importance for the optimal development and function of several biological systems. Ch deprivation has been linked with abnormal fat metabolism, insulin resistance, and myocardial dysfunction. The current study provides evidence of an exacerbation of streptozotocin-induced cardiomyopathy in adult diabetic Wistar rats by dietary Ch deprivation through the administration of a Ch-deprived diet (CDD). Twenty-four adult male Wistar rats were randomly separated into four groups: control, diabetic (DM), choline-deprived through choline-deprived diet (CD), and diabetic choline-deprived (DM + CD). After five weeks of dietary intervention, myocardium echocardiographic and histological assessments were performed. Choline-deprived diabetic rats exhibited significantly slower heart rate, significantly higher myocardial ejection velocity and left ventricle wall tension index with a concomitant significant decreased LV posterior wall thickness as compared to diabetic rats fed on a standard diet. Moreover, histopathological evidence demonstrated an exacerbation of myocardial inflammation and fibrosis associated with significant up-regulation of VEGF expression in the diabetic rat myocardium as a result of Ch deprivation. The study’s findings are of particular significance since the examined experimental approach introduces a previously uncharacterised comorbidity simulation with regards to myocardial structure and functional profiling.

Background. In recent years, diabetes has become a global health problem. Apoptosis of pancreatic beta cells plays an important role in the pathogenesis of type 1 diabetes. Exercise as a non-pharmacological strategy to reduce the diabetic-induced complications has always been of interest to researchers. Therefore, the purpose of this study was to investigate the effect of aerobic exercise on levels of Bax, Bcl-2 and Bax/Bcl-2 ratio in pan­creatic tissue of streptozotocin (STZ)-induced diabetic rats. Materials and methods. A total number of 40 male Wistar rats (10 weeks old, 200–250 gr weight) were randomly divided into healthy control (HC), healthy trained (HT), diabetic control (DC), and diabetic trained (DT) groups. Diabetes was also induced by a single intraperitoneally injection of streptozocin (45 mg/kg). The training groups performed the exercise on the treadmill for five consecutive days within six weeks. The pancreatic tissue levels of the Bax and the Bcl-2 proteins were further determined via ELISA method. Results. The results showed that the induction of diabetes had significantly decreased the levels of Bcl-2 protein and increased the levels of Bax protein and Bax/Bcl-2 ratio in the pancreatic tissue (p < 0.05). As well, the findings showed that six weeks of aerobic exercise training had significantly increased the levels of Bcl-2 and significantly decreased the levels of Bax protein in DT group. Also, the Bax/Bcl-2 ratio reduced significantly in DT group (p < 0.05). The increase in displacement and transmission of apoptosis inducing factor (AIF) that have seen in oxidative stress status, is reduced in the tissues of trained individuals which indica­ting of the inhibition in the apoptotic signaling. Conclusions. According to the results of this study, exercise can be considered as an effective strategy to reduce the rate of diabetic-induced apoptosis and control its complications.

The aim of this study was to know the hypoglycaemic and hypolipidaemic activities of water extract of bungur (Lagerstroemia speciosa [L.] Pers.) leaves in alloxan-induced diabetic rat. Phytochemical studies was conducted to determinate the tannin-contents of the water extract (WE). Male Wistar rats (150- 180 9 BW) were used in this study. The rats were divided into six groups: nonnal control; diabetic control; glibenclamide; WE 0.1 g/200 9 BW; WE 0.2 g/200 9 BW; and WE 0.5 g/200 9 BW. Dried leaves of bungur extracted with boiling water (50 g/L) for 30 minutes. The extract administered orally. Fasting blood glucose, triglyceride, and total cholesterol were determined at 0, 2, 4, 6 hours after treatment. Total phenol, ellagitannin, gallotannin, and condensed-tannin were determined from the WE. The results showed that WE exhibited hypoglycaemic activity at doses 0.2 g/200 9 BW and 0.5 g/200 9 BW. The last dose showed similar hypoglycaemic activity compared with glibenclamide. All doses showed the hypolipidaemic activity higher than glibenclamide. Phytochemical studies showed that the WE containing total phenol 0.025%; ellagitannin 0.011%; gallotannin 0.0199%; and condensed-tannin 0.0167%.

Antinociceptive is reducing sensitivity to painful stimuli for the individual. The objective of this study was to evaluate the antinociceptive potentials of graded doses of Pleurotus ostreatus (Oyster Mushroom) aqueous extract in Rattus norvegicus (Albino Rats) and its chemical pattern by comparing it with a standard drug and a control using the hot water based flick tail test. Thirty five adult rats of both sexes were used for the experiment which, were divided into five groups of seven rats per group. Group one was used as the control (with 1ml normal saline), while groups two, three and four were treated with 100, 200 and 400 mg/kg of Pleurotus ostreatus aqueous extracts and group five treated with 15 mg/kg Aspirin (a standard drug) as positive control. Hot water at 550C was used to determine the nociceptive responses of the animals to detect anti-nociceptive effects of Pleurotus ostreatus extracts as compared to the control in hot water inflicted pain. The results suggested that Pleurotus ostreatus aqueous extract exhibits antinociceptive properties against thermal stimulus at 550C. The diversity of individual animals’ pain tolerance threshold when immersed in hot water was also observed during the experiment. However, the extract indicated a high degree of anti-nociceptive effect at 30, 60, 90 and 120 minutes post treatment period, with a progressively longer threshold time for pain sensitivity. It was also found that at 90 minute period, the control portrayed a relatively short response time.KEY WORDS: Anti-nociceptive, threshold pain, Pleurotus ostreatus, hot water test flick tail.

The study was designed to evaluate the glucose and cholesterol lowering effect of the aqueous extract of Centella asiatica leaf using the alloxan-induced diabetic rats and compared the activity with diabetic control and antidiabetic drug (Glibenclamide). Leaf extract (50 mg/kg) of C. asiatica and Glibenclamide were administered to normal and experimental diabetic rats for the duration of 10 days. In the alloxan-induced diabetic rat model, C. asiatica extract (50 mg/kg) significantly (p < 0.05) lowered the fasting blood glucose level as well as the total cholesterol level. Serum insulin levels were not stimulated in the animals treated with the extract. In addition, changes in body weight, serum lipid profiles and liver glycogen levels assessed in the extract treated diabetic rats were compared with diabetic control and normal animals. Significant results (p < 0.05) were observed in the estimated parameters. Surprisingly, body weight was increased significantly (p < 0.05) in the C. asiatica treated diabetic group. Phytochemical screening showed the presence of alkaloids, flavonoids, glycosides, steroids and tannins in significant amountsJahangirnagar University J. Biol. Sci. 4(1): 51-59, 2015 (June)
