Abstract Background Curcuma amada is the most popular traditional medicine in India for the treatment of diabetes. The present study aimed to focus the antidiabetic and antioxidative activity of C. amada through the analysis of biochemical and genomic levels in a dose-dependent manner in streptozotocin-induced male adult rat. Method Streptozotocin-induced diabetic rats were administered orally with hydro-methanolic extract of C. amada at the dose of 10, 20, 40 and 80 mg/100 g body weight of rats for 28 days. The antidiabetic and antioxidative efficacy of the extract on glycemic, enzymatic, genomic and histological sensors along with toxicity study was investigated. Results The result showed a significant antidiabetic and antioxidative effect of the extract at dose-dependent manner. The significant recovery of fasting blood glucose level, serum insulin, activity of carbohydrate metabolic enzymes and antioxidative enzymes in extract-treated diabetic group as compared to untreated diabetic group were noted. After the extract treatment, the size of pancreatic islet and cell population densities were significantly increased. Activities of glutamate oxaloacetate transaminase and glutamate pyruvate transaminase in liver were significantly recovered along with the correction of Bax and Bcl-2 gene expression in hepatic tissue after the extract treatment in diabetic rats in respect to untreated diabetic group. Out of all the doses, the significant effects were noted at the dose of 20 mg/100 g body weight which has been considered as threshold dose in the concern. Conclusion It may be concluded that the significant and corrective effect in most of the sensors was noted at the minimum dose of 20 mg/100 g body weight of hydro-methanolic extract of C. amada without producing any toxicity.

Traditionally, in many countries, various parts of the Adansonia digitata (A. digitata) tree have been used in the treatment of many clinical ailments including diarrhea and dysentery. The phytochemical screening has indicated that the leaf extract of A. digitata contains flavonoids, saponins, mucilage, steroids, and alkaloids. Thus, this paper aims to evaluate the hyperglycaemic and hypolipidaemic effects of methanolic extract of A. digitata leaves (200 mg/kg and 400 mg/kg) in diabetic rats. The extract was administered orally for six weeks in the streptozotocin (STZ)-induced diabetic rats. The treatment with the extract caused a significant reduction in the blood glucose, glycosylated hemoglobin, cholesterol, triglycerides, low-density lipoprotein (LDL), interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-α), and malondialdehyde (MDA) levels by 46.7%, 46.15%, 48.91%, 43%, 60%, 66%, 45.45%, and 30.4%, respectively, as compared to the diabetic group after the sixth week of treatment. The leaf extract also mitigated the decline of high-density lipoprotein (HDL) level, RBCs count, hemoglobin level, packed cell volume (PCV %), and erythropoietin concentration in diabetic rats by 31%, 33.25%, 24.72%, 51.42%, and 220.68% with respect to the diabetic group. Also, the extract maintained the level of antioxidant enzymes, catalase (CAT) and superoxide dismutase (SOD), and reduced glutathione (GSH) in the diabetic rats. It also reduced the elevation in the white blood corpuscles (WBC) count in the STZ-induced diabetic rats. Our study, therefore, indicates that methanolic extract of A. digitata leaf exerts strong antidiabetic and hypolipidaemic properties in a dose-dependent manner by improving the hematological properties and redox parameters in the experimental diabetic rats.

Pseudarthria hookeri (Fabaceae) is a plant used in traditional medicine in Ivory Coast to treat diabetes. This study aims to evaluate the antidiabetic effects of the aqueous extract of Pseudarthria hookeri (EAPh) on the release and storage of hepatic glucose in alloxan induced diabetic rats. The administration of EAPh, at a dose of 1200 mg/kg body weight for 28 days, leads to a significant decrease of glycaemia in diabetic rats. The oral administration of EAPh, at doses of 800 mg/kg, 1000 mg/kg and 1200 mg/kg body weight, reduced for 60 min, in a dose-dependent manner, the release of hepatic glucose in normoglycemic rats. Moreover, for 90 days of treatment, EAPh significantly promotes the storage of hepatic glucose in diabetic rats. It appears that the aqueous extract of Pseudarthria hookeri has antidiabetic properties and acts by promoting the storage of hepatic glucose (glycogenesis), and by inhibiting the release of glucose from the liver (glycogenolysis). These results justify the use of Pseudarthria hookeri in traditional medicine to effectively treat diabetes.

AbstractBackgroundThe present investigation focuses the diabetes-induced testicular hypofunction and its possible correction by the effective dose of ethyl-acetate fraction of methanolic extract ofMethodsThe androgenic, spermiological, oxidative stress and apoptosis sensors along with testicular genomic sensors were evaluated in a dose-dependent fashion (50 mg or 100 mg or 200 mg/kg body weight). Activities of hepatic transaminases for toxicity assessment were also measured.ResultsIncreased level of fasting blood glucose, testicular cholesterol, seminal vesicular fructose along with a low count, motility and viability of epididymal sperm, low activities of testicular Δ5, 3β-hydroxy steroid dehydrogenase (HSD), 17β-HSD, testicular antioxidant enzymes (catalase and superoxide dismutase) and low plasma level of testosterone were noted in diabetic rat in respect to the control. After oral administration of said fraction to diabetic rat, levels of above sensors were resettled toward the control. A significant decrease in the number of different generations of germ cells at the stage VII of spermatogenesis in diabetic rat was noted which were recovered significantly toward the control in the fraction-treated diabetic group. It was supported by the correction in gene expression of testicular Δ5, 3β- HSD, 17β- HSD, Bcl-2 and Bax in the fraction-treated diabetic group.ConclusionsThe threshold dose of ethyl-acetate fraction of methanolic extract of

In diabetes mellitus, cardiac fibrosis is characterized by increase in the deposition of collagen fibers. The present study aimed to observe the effect ofMomordica charantia(MC) fruit extract on hyperglycaemia-induced cardiac fibrosis. Diabetes was induced in the male Sprague-Dawley rats with a single intravenous injection of streptozotocin (STZ). Following 4 weeks of STZ induction, the rats were subdivided (n= 6) into control group (Ctrl), control group treated withMC(Ctrl-MC), diabetic untreated group (DM-Ctrl), diabetic group treated withMC(DM-MC), and diabetic group treated with 150 mg/kg of metformin (DM-Met). Administration ofMCfruit extract (1.5 g/kg body weight) in diabetic rats for 28 days showed significant increase in the body weight and decrease in the fasting blood glucose level. Significant increase in cardiac tissues superoxide dismutase (SOD), glutathione contents (GSH), and catalase (CAT) was observed followingMCtreatment. Hydroxyproline content was significantly reduced and associated morphological damages reverted to normal. The decreased expression of type III and type IV collagens was observed under immunohistochemical staining. It is concluded thatMCfruit extract possesses antihyperglycemic, antioxidative, and cardioprotective properties which may be beneficial in the treatment of diabetic cardiac fibrosis.

We examined the effects of vanadium sulfate (VOSO4) treatment at 5 and 10 mg/kg for 30 days on endocrine pancreas activity and histology in nondiabetic and STZ-induced diabetic rats. In diabetic group, blood glucose levels significantly increased while insulinemia level markedly decreased. At the end of treatment, VOSO4at a dose of 10 mg/Kg normalized blood glucose level in diabetic group, restored insulinemia, and significantly improved insulin sensitivity. VOSO4also increased in a dose-dependent manner the number of insulin immunopositive beta cells in pancreatic islets of nondiabetic rats. Furthermore, in the STZ-diabetic group, the decrease in the number of insulin immunopositive beta cells was corrected to reach the control level mainly with the higher dose of vanadium. Therefore, VOSO4treatment normalized plasma glucose and insulin levels and improved insulin sensitivity in STZ-experimental diabetes and induced beta cells proliferation and/or regeneration in normal or diabetic rats.

The effect of betanin on a rat paraquat-induced acute lung injury (ALI) model was investigated. Paraquat was injected intraperitoneally at a single dose of 20 mg/kg body weight, and betanin (25 and 100 mg/kg/d) was orally administered 3 days before and 2 days after paraquat administration. Rats were sacrificed 24 hours after the last betanin dosage, and lung tissue and bronchoalveolar lavage fluid (BALF) were collected. In rats treated only with paraquat, extensive lung injury characteristic of ALI was observed, including histological changes, elevation of lung : body weight ratio, increased lung permeability, increased lung neutrophilia infiltration, increased malondialdehyde (MDA) and myeloperoxidase (MPO) activity, reduced superoxide dismutase (SOD) activity, reduced claudin-4 and zonula occluden-1 protein levels, increased BALF interleukin (IL-1) and tumor necrosis factor (TNF)-αlevels, reduced BALF IL-10 levels, and increased lung nuclear factor kappa (NF-κB) activity. In rats treated with betanin, paraquat-induced ALI was attenuated in a dose-dependent manner. In conclusion, our results indicate that betanin attenuates paraquat-induced ALI possibly via antioxidant and anti-inflammatory mechanisms. Thus, the potential for using betanin as an auxilliary therapy for ALI should be explored further.
