Hyperglycemia-associated Alzheimer's-like symptoms and other behavioral effects attenuated by Plumeria obtusa L. Extract in alloxan-induced diabetic rats. Front Pharmacol 2022; 13:1077570. [PMID: 36588726 PMCID: PMC9800837 DOI: 10.3389/fphar.2022.1077570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Accepted: 11/24/2022] [Indexed: 12/23/2022] Open
Abstract
Diabetes mellitus is a chronic metabolic complaint with numerous short- and long-term complications that harm a person's physical and psychological health. Plumeria obtusa L. is a traditional medicine used in the treatment of diabetes to reduce complications related to behavior. Plumeria is a genus with antipsychotic activities. The objective of this study was to examine the effects of a methanolic extract of Plumeria obtusa L. in the attenuation of diabetes, on symptoms of Alzheimer disease, and on other associated behavioral aspects. A single dose of alloxan was administered to an experimental group of rats to induce development of diabetes (150 mg/kg, intraperitoneal) and the rats were then administered selected doses of methanolic extract of Plumeria obtusa L. (Po.Cr) or glibenclamide (0.6 mg/kg) for 45 consecutive days. Behavioral effects were evaluated using three validated assays of anxiety-related behavior: the open field test, the light and dark test, and the elevated plus maze. Anti-depressant effects of Plumeria obtusa L. were evaluated using the forced swim test (FST) and memory and learning were assessed using the Morris water maze (MWM) task. Po.Cr was also evaluated for phytochemicals using total phenolic content (TPC), total flavonoid content (TFC), and high-performance liquid chromatography assays, and antioxidant capability was assessed through assays of DPPH radical scavenging, total oxidation capacity, and total reducing capacity. In the alloxan-induced model of diabetes, the administration of Po.Cr and glibenclamide for 45 days produced a marked decrease (p < 0.001) in hyperglycemia compared to control animals. Po.Cr treatment also resulted in improvement in indicators, such as body weight and lipid profile (p < 0.05), as well as restoration of normal levels of alanine transaminase (ALT) (p < 0.001), a biomarker of liver function. Diabetic rats presented more Alzheimer-like symptoms, with greater impairment of memory and learning, and increased anxiety and depression compared to non-diabetic normal rats, whereas treated diabetic rats showed significant improvements in memory and behavioral outcomes. These results demonstrate that Po.Cr reversed alloxan-induced hyperglycemia and ameliorated Alzheimer-related behavioral changes, which supports additional study and assessment of conventional use of the plant to treat diabetes and associated behavioral complications.

Vulgarin, a Sesquiterpene Lactone from Artemisia judaica, Improves the Antidiabetic Effectiveness of Glibenclamide in Streptozotocin-Induced Diabetic Rats via Modulation of PEPCK and G6Pase Genes Expression. Int J Mol Sci 2022; 23:ijms232415856. [PMID: 36555498 PMCID: PMC9781739 DOI: 10.3390/ijms232415856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 12/11/2022] [Accepted: 12/12/2022] [Indexed: 12/15/2022] Open
Abstract
The current investigation assessed the effect of the eudesmanolid, Vulgarin (VGN), obtained from Artemisia judaica (A. judaica), on the antidiabetic potential of glibenclamide (GLB) using streptozotocin (STZ) to induce diabetes. Seven groups of rats were used in the study; the first group received the vehicle and served as normal control. The diabetic rats of the second to the fifth groups were treated with the vehicle (negative control), GLB at 5 mg/kg (positive control), VGN at 10 mg/kg (VGN-10) and VGN at 20 mg/kg (VGN-20), respectively. The diabetic rats of the sixth and seventh groups were administered combinations of GLB plus VGN-10 and GLB plus VGN-20, respectively. The diabetic rats treated with GLB plus VGN-20 combination showed marked improvement in the fasting blood glucose (FBG), insulin and glycated hemoglobin (HbA1c), as well as the lipid profile, compared with those treated with GLB alone. Further, the pancreatic tissues of the diabetic rats that received the GLB+VGN-20 combination showed superior improvements in lipid peroxidation and antioxidant parameters than those of GLB monotherapy. The insulin content of the β-cells was restored in all treatments, while the levels of glucagon and somatostatin of the α- and δ-endocrine cells were reduced in the pancreatic islets. In addition, the concurrent administration of GLB+VGN-20 was the most effective in restoring PEPCK and G6Pase mRNA expression in the liver. In conclusion, the results demonstrated that the GLB+VGN-20 combination led to greater glycemic improvement in diabetic rats compared with GLB monotherapy through its antioxidant effect and capability to modulate PEPCK and G6Pase gene expression in their livers.

Anti-Diabetic Effects of Allium hookeri Extracts Prepared by Different Methods in Type 2 C57BL/J- db/db Mice. Pharmaceuticals (Basel) 2022; 15:ph15040486. [PMID: 35455483 PMCID: PMC9024442 DOI: 10.3390/ph15040486] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 04/08/2022] [Accepted: 04/12/2022] [Indexed: 02/07/2023] Open
Abstract
This study was conducted to evaluate whether Allium hookeri can control diabetic symptoms. Aqueous extract (AE1: 100 mg/kg BW, AE2: 200 mg/kg BW) and ethanol extract (EE1: 100 mg/kg BW, EE2: 200 mg/kg BW) of A. hookeri were orally administrated to diabetic mice (C57BL/J-db/db) for 8 weeks. The negative (NC) and the positive (PC) control groups were treated with 0.9% saline and metformin (150 mg/kg BW), respectively. Glucose and lipid profile (triglyceride, total cholesterol (TC), LDL-C, and HDL-C) as biochemical parameters, toxicological factors such as liver/kidney functional parameters (ALT, AST, BUN, and Cr), and NK cell activity in blood were measured. Oral glucose tolerance test (OGTT) and histopathological examination were also conducted. Compared with the NC group, AE and EE decreased blood glucose, HbA1c, area under the curve (AUC) during OGTT, and leptin levels while increasing adiponectin levels. Serum lipid profiles and toxicological factors levels were reduced by the A. hookeri extract. Interestingly, HDL-C, glomerular mesangial expansion score in the kidney, and NK cell activity were effectively controlled in EE groups. Based on the results, EE is considered to be more effective in reducing high blood glucose, lipid profile, and related factor levels than AE, and is comparable to metformin in some biomarkers. It can be presumed that EE can more effectively control the major anomalies in the diabetic model than AE, and it may be used to prevent diabetic symptoms without toxicity in the Type 2 diabetic model.

Abstract
This work analysed the chemical composition, antioxidant, and enzyme inhibitory activities of solvent extract (SJ-ME) and fractions (SJ-HF, SJ-EAF, and SJ-MF) of the Stachys riederi var. japonica (Miq.) (SJ). Furthermore, the effect of SJ-EAF in STZ induced type 2 diabetic mice was examined. Among the samples, SJ-EAF exhibited a lower IC50 concentration of 64.2 ± 0.48 μg/mL for DPPH and 82.6 ± 0.09 μg/mL for ABTS+. The SJ-EAF concentration of 2.89 ± 0.03 μg and 2.27 ± 0.98 μg was equivalent to 1 μg of acarbose mediated enzyme inhibitory effect against α-amylase and α -glucosidase, respectively. The SJ-EAF did not show cytotoxicity (<80%) to NIH3T3 nor HepG2 cells but enhanced the glucose uptake in the IR-HepG2. LC-MS/MS of SJ-EAF showed the presence of a total of 16 compounds. Among the identified compounds, rosmarinic acid, caffeic acid, oleanolic acid, and ursolic acid showed high catalytic activity of α-amylase and α-glucosidase. The treatments of SJ-EAF restored the level of blood glucose, body weight, insulin, HDL and mRNA level of IRS1, GLUT2, GLUT4 and Akt whereas it reduced the excess elevation of total cholesterol, total triglycerides, LDL, AST, ALT, ALP, BUN, and creatinine in STZ induced diabetic mice. Overall, the present study concluded that the SJ-EAF exhibited promising antidiabetic activity.

Abstract
BACKGROUND Periploca aphylla is used by local population and indigenous medicine practitioners as stomachic, tonic, antitumor, antiulcer, and for treatment of inflammatory disorders. The aim of this study was to evaluate antidiabetic effect of the extract of P. aphylla and to investigate antioxidant and hypolipidemic activity in streptozotocin (STZ)-induced diabetic rats. METHODS The present research was conducted to evaluate the antihyperglycemic potential of methanol extract of P. aphylla (PAM) and subfractions n-hexane (PAH), chloroform (PAC), ethyl acetate (PAE), n-butanol (PAB), and aqueous (PAA) in glucose-overloaded hyperglycemic Sprague-Dawley rats. Based on the efficacy, PAB (200 mg/kg and 400 mg/kg) was tested for its antidiabetic activity in STZ-induced diabetic rats. Diabetes was induced via intraperitoneal injection of STZ (55 mg/kg) in rat. Blood glucose values were taken weekly. HPLC-DAD analysis of PAB was carried out for the presence of various polyphenols. RESULTS HPLC-DAD analysis of PAB recorded the presence of rutin, catechin, caffeic acid, and myricetin. Oral administration of PAB at doses of 200 and 400 mg/kg for 21 days significantly restored (P < 0.01) body weight (%) and relative liver and relative kidney weight of diabetic rats. Diabetic control rats showed significant elevation (P < 0.01) of AST, ALT, ALP, LDH, total cholesterol, triglycerides, LDL, creatinine, total bilirubin, and BUN while reduced (P < 0.01) level of glucose, total protein, albumin, insulin, and HDL in serum. Count of blood cells and hematological parameters were altered in diabetic rats. Further, glutathione peroxidase, catalase, superoxide dismutase, glutathione reductase, and total soluble protein concentration decreased while concentration of thiobarbituric acid reactive substances and percent DNA damages increased (P < 0.01) in liver and renal tissues of diabetic rats. Histopathological damage scores increased in liver and kidney tissues of diabetic rats. Intake of PAB (400 mg/kg) resulted in significant improvement (P < 0.01) of above parameters, and results were comparable to that of standard drug glibenclamide. CONCLUSION The result suggests the antihyperglycemic, antioxidant, and anti-inflammatory activities of PAB treatment in STZ-compelled diabetic rat. PAB might be used as new therapeutic agent in diabetic patients to manage diabetes and decrease the complications.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Leaves of Alnus nitida are used by local communities for the management of diabetes and in inflammatory disorders. METHODS Powder of shade dried leaves of A. nitida was extracted with methanol (ANME) and fractionated in escalating polarity i.e n-hexane (ANHE), chloroform (ANCE), ethyl acetate (ANEE) and soluble residual aqueous fraction (ANAE). The extract/fractions were evaluated for antidiabetic in vitro assays; α-amylase, α-glucosidase and dipeptidyl peptidase-4 (DPP-4). The in vivo investigations were carried out on ANEE and ANAE (100 mg/kg; 200 mg/kg, p.o.) in alloxan (125 mg/kg i.p.) induced hyperglycemic rats. Serum analysis was performed on liver, pancreas and kidney function markers. Analysis of antioxidant enzymes and genotoxic studies were carried out on pancreas, liver and kidneys tissues. GC-MS analysis was performed on ANME whereas HPLC analysis was carried out on ANME, ANEE and ANAE. RESULTS Preliminary in vitro assays indicated appreciable antidiabetic activity of ANEE and ANAE against α-amylase, α-glucosidase and DPP-4 assay. Furthermore, in vivo antidiabetic effect of ANEE and ANAE was inveterate by anti-hyperglycemic action in normal glucose loaded and diabetic glucose loaded animals. Single dose of alloxan (125 mg/kg) decreased the level of insulin and high density lipoprotein while raised the level of amylase and lipase, ALT, AST, total lipids, triglycerides, cholesterol, creatinine, BUN, CPK, CK-Mb in serum. Concentration of H2O2, lipid peroxidation (TBARS) and nitrite was increased (P < 0.05) whereas level of tissue protein, glutathione content (GSH) and antioxidant enzymes decreased in pancreas, liver and kidneys as compared to control group. Administration of ANEE and ANAE for 14 days after induction of diabetes decreased the hyperglycemia and restored the level of these parameters. Histopathological and genotoxic studies also endorsed the defensive strategies of ANEE and ANAE. GC-MS analysis of ANME demonstrated the presence of antidiabetic constituents i.e. linalool, Vitamin E and phytol. CONCLUSION Results obtained in this study suggests antidiabetic and antioxidant abilities and provides the scientific proof of the folklore medicine.

Saudi Pharm J 2019; 27:1182-1195. [PMID: 31885478 PMCID: PMC6921200 DOI: 10.1016/j.jsps.2019.10.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Accepted: 10/02/2019] [Indexed: 02/02/2023] Open
Abstract
The concomitant use of olive leaves (OL) and glyburide (GLB) is a possible therapy for diabetic patients. However, there is no report about the effect of OL on the antidiabetic effect of GLB till now. In the current study, the possible interaction of olive leaves extract (OLE) with GLB was assessed to determine if there was any pharmacological benefit over GLB alone. Seven groups of male Sprague Dawley rats were used. Normal rats of the 1st group treated with 2 mL/kg of 3% Tween 80 (vehicle). The 2nd–5th groups were diabetic rats received vehicle, GLB (5 mg/kg), OLE low dose and OLE high dose respectively, while the 6th–7th groups administered combinations of GLB plus OLE low dose and GLB plus OLE high dose, respectively. All treatments were administered orally once daily for 8 weeks. The use of GLB+OLE-500 obviously improved fasting blood glucose (FBG), insulin and glycated hemoglobin (HbA1c) in diabetic rats (95.5 ± 5.55 mg/dL, 6.8 ± 0.16 mg/dL and 6.1 ± 0.29%, respectively) compared to those treated with GLB monotherapy (140.0 ± 6.36 mg/dL, 5.4 ± 0.19 mg/dL and 7.0 ± 0.20%, respectively). The lipid profile [triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C)] was significantly improved in diabetic rats exposed to GLB+OLE-500 (35.6 ± 1.51 mg/dL, 48.5 ± 2.74 mg/dL, 25.1 ± 1.21 mg/dL and 17.0 ± 0.82 mg/dL, respectively) in comparison with diabetic group exposed to GLB alone (43.2 ± 2.15 mg/dL, 56.8 ± 2.14 mg/dL, 18.6 ± 0.96 mg/dL, 23.0 ± 1.26 mg/dL, respectively). Additionally, the benefit impacts of GLB+OLE-500GLB+OLE-500 therapy on the antioxidant and lipid peroxidation parameters in the pancreatic tissues of diabetic rats were higher than those of GLB monotherapy. Moreover, GLB plus OLE-500 combination had the greatest effect on restoration of the insulin content of Beta (β) cells and reduction of the glucagon and somatostatin of Alpha (α) and Delta (δ) endocrine cells in the pancreatic islets among the different treatment. The current study suggests that OL and GLB combination could cause herb-drug interactions through modulation of insulin receptor (INR), glucose transporter 2 (Slc2a2) and peroxisome proliferator-activated receptor α (PPAR-α) genes expression in the liver of diabetic rats.

JOURNAL OF ETHNOPHARMACOLOGY 2019; 242:112038. [PMID: 31247238 DOI: 10.1016/j.jep.2019.112038] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/05/2019] [Revised: 06/12/2019] [Accepted: 06/22/2019] [Indexed: 06/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fagonia olivieri (Zygophyllaceae) is used in Pakistan for management of diabetes and for treatment of stress related disorders of liver and kidneys. The objective of present study was to evaluate antidiabetic activity of F. olivieri using streptozotocin-nicotinamide induced diabetic rat model. METHODS Powder of the whole plant of F. olivieri was extracted with methanol (FOME) and the residue was fractionated with n-hexane (FOHE), chloroform (FOCE), ethyl acetate (FOCE), n-butanol (FOBE) and the remaining soluble aqueous fraction (FOAE). The extract/fractions were evaluated for in vitro inhibition of α-amylase and α-glucosidase and for the antidiabetic studies in Sprague-Dawley rats. FOAE was evaluated in 21 day chronic multiple dose study. Glibenclamide (10 mg/kg) and FOAE were used at a concentration of 200 mg/kg (164.8 μg of catechin) and 400 mg/kg (329.6 μg of catechin) in streptozotocin (STZ)-induced diabetic rats. Various serum parameters, blood cell parameters and oxidative stress induced parameters of the liver and kidneys were investigated. RESULTS Results showed that aqueous fraction of F. olivieri (FOAE) potentially inhibited activity of pancreatic α-amylase, intestinal maltase and sucrase. Administration of FOAE (200 mg/kg; 400 mg/kg) to diabetic rats for 21 days increased body weight, hemoglobin and its indices, RBCs, platelets, lymphocytes and neutrophils against diabetic group. In serum level of glucose, transaminases, ALP, LDH, total bilirubin, creatinine and lipids decreased while insulin, total protein and albumin increased in contrast to diabetic group. Further, level of cytokines; TGF-β1, TNF-α and IL-6 in serum and altered level of antioxidant enzymes, glutathione and lipid peroxides of liver and kidney tissues restored towards control animals. CONCLUSION This study demonstrated that FOAE inhibited activity of digestive enzymes and exhibited antioxidant, anti-inflammatory and antihyperglycemic activity in STZ-nicotinamide prompted diabetic rats and suggested that FOAE might be used as a therapeutic agent for the management of type-2 diabetes.

Don leaf extracts in alloxan-induced diabetic rats. 3 Biotech 2019; 9:308. [PMID: 31355117 PMCID: PMC6661051 DOI: 10.1007/s13205-019-1840-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Accepted: 07/16/2019] [Indexed: 12/15/2022] Open
Abstract
Efficacy of several plant extracts in the clinical research for modulating oxidative stress correlated with diabetes mellitus (DM) is well documented. In the present study, we investigated the in vitro antioxidant activity, toxicity, and anti-diabetic activity of methanolic extract of Hippophae salicifolia leaves in normal and alloxan-induced diabetic wistar rats. H. salicifolia leaves were found to be rich in antioxidants. The acute toxicity test of methanolic extract of H. salicifolia leaves revealed that the median lethal dose (LD50) was found to be 3.92 g/kg body weight in mice. Administration of H. salicifolia leaves at 200 mg/kg and 400 mg/kg in alloxan-induced diabetic rats illustrated significant reduction (22% and 39%, respectively) in fasting blood glucose compared to diabetic control. Both the doses were found to be effective when compared to diabetic rats. The Hippophae-treated diabetic rats showed significant increase in the endogenous antioxidant enzymes, superoxide dismutase (50% and 74%, respectively), glutathione peroxidase (57% and 41%, respectively) and decrease in malondialdehyde (33% and 15%, respectively) levels. These results suggested that the methanolic leaf extract of H. salicifolia enhanced the antioxidant defence against reactive oxygen species produced under hyperglycaemic conditions.

Abstract
Momordica charantia is used in folk medicine to manage diabetes mellitus. In this study, we investigated the possible herb-drug interaction between M. charantia fruit extract (MCFE) and glibenclamide (GLB) in streptozotocin-diabetic rats. Rats were divided into 7 groups. The 1st group received 3% Tween 80. The 2nd–5th groups were diabetic rats received vehicle, GLB (5 mg/kg), MCFE (250 and 500 mg/kg), respectively. The 6th–7th groups administered GLB plus MCFE (250 and 500 mg/kg), respectively. After 8 weeks, fasting blood glucose (FBG), insulin and glycosylated hemoglobin (HbA1c) levels were assessed. Histopathological and immunohistochemical examinations of the pancreases were done. Quantitative RT-PCR was used to analyze hepatic mRNA expression of insulin receptor (INR), glucose transporter 2 (Slc2a2) and peroxisome proliferator-activated receptor α (PPAR-α) genes. All medicaments greatly reduced FBG in diabetic rats when compared with diabetic control group. GLB plus MCFE combination was better than GLB alone in improving levels of insulin and HbA1c. All medicaments restored insulin content of pancreatic β-cells and reduced glucagon and somatostatin of alpha and delta endocrine cells. Moreover, GLB plus MCFE-500 was the most efficient in restoring INR, Slc2a2 and PPAR-α mRNA expression to their normal levels. In conclusion, MCFE in combination with GLB gives greater glycemic improvement than GLB monotherapy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Parkia biglobosa seeds are used to treat diabetes and complications hence this study. AIM This study investigated the effects of Parkia biglobosa aqueous seed extract on some biochemical, haematological and histopathological indices in streptozotocin-induced diabetic rats. MATERIALS AND METHODS Wistar rats of either sex (180-300 g) were fasted overnight and diabetes mellitus induced using streptozotocin 40 mg/kg IP. Diabetes mellitus (fasting blood glucose ≥ 200 mg/dl) was confirmed 48 h later. The rats were randomly grouped into six groups (n = 5): Group 1 (diabetic untreated control), group 2 (Parkia biglobosa 200 mg/kg), group 3 (Parkia biglobosa 400 mg/kg). group 4 (Parkia biglobosa 800 mg/kg), group 5 (glibenclamide 5 mg/kg as standard drug control) and group 6 (normoglycaemic control). They were treated daily. Acute toxicity study and phytochemical screening were also performed. Fourteen days later, they were sacrificed under chloroform anaesthesia. Vital organs (kidneys, liver and pancreas) and blood samples were obtained for histopathological, biochemical and haematological analysis. RESULTS Parkia biglobosa aqueous seed extract at the various doses caused significant (P < 0.05) elevations in red blood cell parameters in comparison to the diabetic control. The mean cell volume did not differ significantly from the diabetic control while 200 mg/kg and 400 mg/kg doses of the extract did not significantly modify the HCT levels. Treatment with Parkia biglobosa significantly (P < 0.05) lowered white blood cell and platelet counts in comparison to the diabetic control. Liver enzymes and total bilirubin levels were significantly (P < 0.05) reduced while total protein increased in the treated diabetic rats in comparison to controls. Treatment with Parkia biglobosa extract significantly (P < 0.05) increased bicarbonate and sodium ion levels while decreasing potassium ion levels. Chloride levels were not significantly different from the diabetic control. CONCLUSION These data suggest that Parkia biglobosa ameliorates biochemical, haematological and histopathological changes associated with diabetes mellitus.

Abstract
Objective To evaluate the hypoglycemic effect of Picris japonica Thunb (Asteraceae) on KK-Ay mice. Methods The hypoglycemic effect of Picris japonica aqueous extract (PJE) in a spontaneous type 2 diabetic model (KK-Ay mice) was studied in the present research. PJE was administrated at doses of 700 mg/kg and 350 mg/kg (calculated as crude herb) for 14 days and blood glucose, oral glucose tolerance test, plasma insulin level, and blood lipid were evaluated. Meanwhile, Rosiglitazone was used for the positive control. Results It was found the PJE treatment significantly reduced blood glucose level and improved oral glucose tolerance ability (p < 0.01 or p < 0.05) in a dose-dependent manner compared to the control diabetic mice. The blood insulin levels were significantly reduced in PJE-treated mice (700 mg/kg) and Rosiglitazone compared with the diabetic control (p < 0.01). Compared with the control diabetic group, the serum total cholesterol, triglyceride, and low density lipoprotein cholesterol were reduced by PJE (700 mg/kg) and Rosiglitazone (p < 0.05), and the serum high density lipoprotein cholesterol was significantly increased only by Rosiglitazone (p < 0.01). Conclusions The findings demonstrate that Picris japonica has remarkable antidiabetic effect in diabetic KK-Ay mice, which suggests that Picris japonica may be beneficial to the treatment of type 2 diabetes mellitus.

Abstract
Sida tuberculata (ST) is a Malvaceae species widely distributed in Southern Brazil. In traditional medicine, ST has been employed as hypoglycemic, hypocholesterolemic, anti-inflammatory and antimicrobial. Additionally, this species is chemically characterized by flavonoids, alkaloids and phytoecdysteroids mainly. The present work aimed to optimize the extractive technique and to validate an UHPLC method for the determination of 20-hydroxyecdsone (20HE) in the ST leaves. Box-Behnken Design (BBD) was used in method optimization. The extractive methods tested were: static and dynamic maceration, ultrasound, ultra-turrax and reflux. In the Box-Behnken three parameters were evaluated in three levels (-1, 0, +1), particle size, time and plant:solvent ratio. In validation method, the parameters of selectivity, specificity, linearity, limits of detection and quantification (LOD, LOQ), precision, accuracy and robustness were evaluated. The results indicate static maceration as better technique to obtain 20HE peak area in ST extract. The optimal extraction from surface response methodology was achieved with the parameters granulometry of 710 nm, 9 days of maceration and plant:solvent ratio 1:54 (w/v). The UHPLC-PDA analytical developed method showed full viability of performance, proving to be selective, linear, precise, accurate and robust for 20HE detection in ST leaves. The average content of 20HE was 0.56% per dry extract. Thus, the optimization of extractive method in ST leaves increased the concentration of 20HE in crude extract, and a reliable method was successfully developed according to validation requirements and in agreement with current legislation.

Abstract
CONTEXT Echinacea (Asteraceae) is used because of its pharmacological properties. However, there are few studies that integrate phytochemical analyses with pharmacological effects. OBJECTIVE Evaluate the chemical profile and biological activity of hydroalcoholic Echinacea extracts. MATERIALS AND METHODS Density, dry matter, phenols (Folin-Ciocalteu method), flavonoids (AlCl3 method), alkylamides (GC-MS analysis), antioxidant capacity (DPPH and ABTS methods), antiproliferative effect (SRB assay), anti-inflammatory effect (paw oedema assay, 11 days/Wistar rats; 0.4 mL/kg) and hypoglycaemic effect (33 days/Wistar rats; 0.4 mL/kg) were determined in three Echinacea extracts which were labelled as A, B and C (A, roots of Echinacea purpurea L. Moench; B, roots, leaves, flowers and seeds of Echinacea purpurea; C, aerial parts and roots of Echinacea purpurea and roots of Echinacea angustifolia DC). RESULTS Extract C showed higher density (0.97 g/mL), dry matter (0.23 g/mL), phenols (137.5 ± 2.3 mEAG/mL), flavonoids (0.62 ± 0.02 mEQ/mL), and caffeic acid (0.048 mg/L) compared to A and B. A, B presented 11 alkylamides, whereas C presented those 11 and three more. B decreased the oedema (40%) on day 2 similar to indomethacin. A and C showed hypoglycaemic activity similar to glibenclamide. Antiproliferative effect was only detected for C (IC50 270 μg/mL; 8171 μg/mL; 9338 μg/mL in HeLa, MCF-7, HCT-15, respectively). DISCUSSION AND CONCLUSION The difference in the chemical and pharmacological properties among extracts highlights the need to consider strategies and policies for standardization of commercial herbal extracts in order to guarantee the safety and identity of this type of products.

Abstract
Objectives The aim of this study was to investigate the effects of Cassia acutifolia on the obesity and the glucose levels in a rat model of obesity and diabetes. Methods By random selection, 36 Wistar male rats were divided in two control groups, the positive and the negative control groups, and into four experimental groups receiving different infusions of Cassia acutifolia in water ad libitum. Results The results revealed a statistically significant anti-obesogenic effect (P = 0.02), although this was not considered clinically significant. Additionally, Cassia acutifolia lowered the glucose levels by 30 mg/dL to 90 mg/dL (P = 0.05). However, we observed adverse effects in the liver, a two-fold increase in transaminase levels (P = 0.002), and in the kidneys, decreased creatinine levels (P = 0.001), and these adverse effects had no viable explanation. Conclusion Cassia acutifolia has anti-hyperglycemic effects in obese diabetic rats. However, Cassia acutifolia also has adverse effects, so it should not be administered to patients.

Abstract
BACKGROUND This study was designed to investigate the effects of immature carob pod aqueous extract (ICPAE) on intestinal glucose absorption in vitro and in vivo using an oral glucose tolerance test (OGTT) as well as the potential antidiabetic effect in alloxan-induced diabetic rats. OGTT was carried by administration of glucose (2 g kg-1 , p.o.) and after treatment with extract (50, 100 and 200 mg kg-1 body weight). Diabetes was induced by single intraperitoneal injection of alloxan (150 mg kg-1 ). However, the extracts at various doses or glibenclamide (GLB, 10 mg kg-1 body weight) were given by oral administration for 2 weeks. RESULTS ICPAE (50-2000 µg mL-1 ) exerted dose-dependent reduction of sodium-dependent glucose transport across isolated mice jejunum and the maximal inhibition exceeded 50%.The ICPAE treatment improved glucose tolerance. More importantly, ICPAE at various doses showed a significant reduction in blood glucose and biochemical profiles in diabetic rats. CONCLUSION Our findings confirm that the degree of maturity of carob characterized by a different phytochemical composition may be responsible for these actions. Therefore, these compounds may be used as a food supplement in hyperglycemia and diabetes treatments. © 2016 Society of Chemical Industry.

Abstract
Background and aims: Diabetes is one of the most frequent and serious chronic diseases in humans all over the world. The aim of our study was to evaluate the antidiabetic activity of camel milk on serum glucose and lipid profile of alloxan-induced diabetic rats.
Materials and methods: Diabetes was induced in Wistar albino rats by intraperitoneal injection of alloxan (120 mg/kg BW once). Albino rats each weighing 180-230g were divided into 3 equal groups (n=10) as following: G1 - normal rats fed on normal diet, G2 - diabetic rats fed on normal diet, and G3 - diabetic rats were fed with raw camel milk. Fasting blood glucose was measured on days 0, 1, 7, 14, 21 and 30 while lipid profile was assessed at day 30.
Results: After four weeks of feeding, data indicated a significant decrease (p<0.05) of mean blood glucose in G3 group (133.80±3.22 mg/dL) as compared with G2 diabetic rats (199.6± 7.33 mg/dL). Data also revealed significant lower levels (p<0.05) of triglycerides, total cholesterol, LDL and VLDL and higher level of HDL cholesterol in diabetic rats treated with camel milk as compared with diabetic rats fed a normal diet.
Conclusion: Raw camel milk improved the glycemic and lipid profile in diabetic rats. These findings indicate that raw camel milk may have potential benefits in the treatment of diabetes. Future studies will be needed to establish its safety and mechanism of action.

OBJECTIVES To evaluate in vitro and in vivo antioxidant potency of Pistacia chinensis (P. chinensis) bark and leaves extracts along with its protective role against CCl4 induced toxicity in testis of the rat. METHODS Various in vitro models such as DPPH, ABTS, hydrogen peroxide, superoxide, hydroxyl and nitric oxide scavenging activities, anti-lipid peroxidation activity, phospho-molybdenum activity, β carotene bleaching assay was used for analysis of antioxidant potential. Experimental groups for in vivo study were: Group Ⅰ (control) untreated, Group Ⅱ (Vehicle control), Group Ⅲ (1 mL/kg b.w 30% CCl4), Group Ⅳ (1 mL/kg b.w CCl4 + Silymarin), Group Ⅴ (200 mg/kg b.w PCBE + CCl4), Group Ⅵ (400 mg/kg b.w PCBE + CCl4) and Group Ⅶ (400 mg/kg b.w PCBE alone). RESULTS In vitro antioxidant assays displayed significant results and the highest activity was not specified to a specific extract. However, ethyl acetate extract of bark (PCBE) showed highest results in most of the antioxidant assays i.e. beta-carotene bleaching, hydroxyl radical scavenging, ABTS, lipid peroxidation and superoxide radical scavenging activity. On this base, this fraction was selected for in vivo antioxidant experiment. Testis tissues were analyzed to observe the protective effects of PCBE on antioxidant enzymes; catalase, superoxide dismutase, peroxidase, glutathione-S-transferase, glutathione reductase, glutathione peroxidase and quinone reductase activities and glutathione (GSH) as well as nitrite content. Profile of plasma testosterone was also compared to various treatments. Observation suggests a protective role of P. chinensis against CCl4 induced toxicity. CONCLUSIONS It is concluded that some bioactive antioxidants of P. chinensis bark might be a good source to isolate the potent antioxidant components.

[PMID: 27776508 PMCID: PMC5078913 DOI: 10.1186/s12906-016-1398-0] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/22/2016] [Accepted: 10/11/2016] [Indexed: 01/06/2023]
Abstract
BACKGROUND Leaves and root bark of Fraxinus xanthoxyloides Wall. (Oleaceae) are used locally for the treatment of jaundice, malaria and pneumonia. Decoction of stem, twigs and bark is used in pain, internal injuries, rheumatism and in bone fracture. In this investigation we have evaluated the methanol extract of leaves for its hepatoprotective potential against CCl4 induced hepatic injuries in rat. METHODS Powder of F. xanthoxyloides leaves was extracted with methanol (FXM) and subjected for the determination of polyphenolics through HPLC-DAD analysis. Sprague-Dawley (Rattus novergicus) male rats were divided into eight groups (six rats in each). Group I: non-treated control; Group II: vehicle treated (DMSO plus olive oil) while Group III- VI treated with 1 ml/kg body weight (bw) of CCl4 (30 % in olive oil) for 30 days (15 dosages) to induce the hepatic injuries. Group IV: treated with silymarin (100 mg/kg bw); Group V and VI with FXM (200, 400 mg/kg bw) on alternate days with CCl4 treatment. Group VII and VIII was administered with FXM (200, 400 mg/kg bw) alone (15 dosages). After 30 days the serum was evaluated for liver function enzymes and biochemical markers, liver samples for antioxidant enzymes, biochemical markers, comet assay and for histopathology. RESULTS HPLC-DAD analysis of FXM revealed the existence of rutin and caffeic acid. In CCl4 treated rats the level of alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin was significantly increased while the albumin concentration in serum was decreased as compared to control group. The level of hepatic antioxidant enzymes, catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), glutathione-S-transferase (GST) and glutathione reductase (GSR) was significantly decreased against the control group. Further, significant decrease in GSH while increase in lipid peroxides (TBARS), H2O2, DNA damages and comet length was induced with CCl4 in hepatic tissues of rat. In contrast, co-administration of FXM and silymarin restored the biochemical and histopathological status of the liver. CONCLUSION Results of present investigation revealed that F. xanthoxyloides leaves possibly protect the liver against CCl4 induced injuries like silymarin by its antioxidant constituents.

Abstract
Diabetes mellitus is a chronic metabolic disorder with a high prevalence worldwide. Animal models of diabetes represent an important tool in diabetes investigation that helps us to avoid unnecessary and ethically challenging studies in human subjects, as well as to obtain a comprehensive scientific viewpoint of this disease. Although there are several methods through which diabetes can be induced, chemical methods of alloxan- and streptozotocin-induced diabetes represent the most important and highly preferable experimental models for this pathological condition. Therefore, the aim of this article was to review the current knowledge related to quoted models of diabetes, including to this point available information about mechanism of action, particular time- and dose-dependent protocols, frequent problems, as well as major limitations linked to laboratory application of alloxan and sterptozotocin in inducing diabetes. Given that diabetes is known to be closely associated with serious health consequences it is of fundamental importance that current animal models for induction of diabetes should be continuously upgraded in order to improve overall prevention, diagnosis and treatment of this pathological condition.

Abstract
The current study sought to investigate the capacities of single and combinatorial herbal formulations of leaf extracts of Acanthus montanus, Asystasia gangetica, Emilia coccinea, and Hibiscus rosasinensis to reverse hyperglycemia and dyslipidemia in alloxan-induced diabetic male rats. Phytochemical composition of the herbal extracts, fasting plasma glucose concentration (FPGC), and serum lipid profile (SLP) of the rats were measured by standard methods. The relative abundance of phytochemicals in the four experimental leaf extracts was in the following order: flavonoids > alkaloids > saponins > tannins. Hyperglycemic rats (HyGR) treated with single and combinatorial herbal formulations showed evidence of reduced FPGC compared with the untreated HyGR and were normoglycemic (FPGC < 110.0 mg/dL). Similarly, HyGR treated with single and combinatorial herbal formulations showed evidence of readjustments in their SLPs. Generally, HyGR treated with triple herbal formulations (THfs) exhibited the highest atherogenic index compared with HyGR treated with single herbal formulations (SHfs), double herbal formulations (DHfs), and quadruple herbal formulation (QHf). The display of synergy or antagonism by the composite herbal extracts in ameliorating hyperglycemia and dyslipidemia depended on the type and number of individual herbal extract used in constituting the experimental herbal formulations. Furthermore, the capacities of the herbal formulations (SHfs, DHfs, THfs, and QHf) to exert glycemic control and reverse dyslipidemia did not follow predictable patterns in the animal models.
