AbstractObjectivesCistus salviifoluis L. is a shrub from Cistaceae family used in many traditional medicines for the treatment of various diseases including diabetes mellitus. The aim of this study was to evaluate the in vivo antidiabetic potential of the aerial parts aqueous extract of Cistus salviifolius L. (CSA).MethodsExperimental diabetes was induced in adult male mice by intra-peritoneal injection of Streptozotocin-nicotinamide (STZ-NC). CSA at a dose of 500 mg/kg was administered daily to the diabetic mice for four weeks. The effect of the extract on hyperglycemia, body weight, serum total cholesterol, triglycerides, hepatic and renal functional markers were determined. Histopathological examination of the mice pancreas was also performed. The diabetic animals treated with CSA were compared with animals treated by the standard drug metformin.ResultsTreatment with CSA showed a significant reduction in blood glucose, total triglycerides and creatinine levels and prevented the reduction of body weight caused by diabetes. Furthermore, histopathological analysis of the mice pancreas showed that the group treated with CSA reduced damage induced by STZ-NC on islets of Langerhans cells when compared to the diabetic control.ConclusionsThe results suggest that the aqueous extract of Moroccan C. salviifolius L. possesses beneficial effect on treatment of diabetes.

Abstract Background Sophora exigua Craib. is commonly used in Thailand to reduce fever and increase postpartum breast milk production in women who have hypogalactia. However, there has been no report on the antioxidant and antimalarial properties of this plant. This study aimed to investigate the antioxidant and antimalarial activities of S. exigua root extract and to evaluate its acute toxicity in mice to confirm its safety. Methods The in vitro antioxidant activities were determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), superoxide radical, and hydroxyl radical scavenging assays. The in vivo antioxidant activities were determined by detecting the malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in the livers of malaria-infected mice. The in vivo antimalarial activity was determined by Peters’ 4-day suppressive test in mice infected with Plasmodium berghei ANKA and orally administered S. exigua root aqueous and ethanolic extracts at different doses (200, 400, and 600 mg/kg body weight). In addition, the acute oral toxicity of the plant extracts was assessed in mice at a dose of 2000 mg/kg body weight. Results The ethanolic extract of S. exigua root exhibited inhibition of DPPH radicals, superoxide anions, and hydroxyl radicals, with half maximal inhibitory concentration (IC50) values of 24.63 ± 1.78, 129.78 ± 0.65, and 30.58 ± 1.19 μg/ml, respectively. Similarly, research on the in vivo antioxidant activity indicated that the ethanolic extract of S. exigua root exerted a stronger effect than the aqueous extract. The aqueous extract at doses of 200, 400, and 600 mg/kg had stronger antimalarial activity than the ethanolic extract. The aqueous extract at 600 mg/kg exhibited 60.46% suppression of parasitemia. Increased levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) and blood urea nitrogen (BUN) were detected in the mice treated with 2000 mg/kg ethanolic extract, which was related to the results of histopathological analysis of liver tissue, showing ballooning degeneration of hepatocytes, diffuse hepatic hemorrhage, and infiltration of inflammatory cells. Conclusions This study demonstrated that the ethanolic S. exigua root extract possessed antioxidant properties, and the aqueous extract also had antimalarial activity. Therefore, this plant is an alternative source of new antioxidant and antimalarial agents.

Abstract Background Diabetes mellitus (DM) is currently a major health problem and the most common chronic disease worldwide. Traditional medicinal plants remedies remain a potential adjunct therapy to maintain better glycemic control while also imparting few side-effects. Arbutus unedo L. has been traditionally used to manage several diseases including diabetes. This study was undertaken to contribute the validation of the traditional use of Arbutus unedoL. (Ericaceae) in the treatment of diabetes. Methods In-vitro antidiabetic effect of the A. unedo roots aqueous extract was conducted using α-glucosidase and α-amylase assays. While in-vivo antidiabetic activity was conducted using streptozotocin-nicotinamide (STZ-NA) induced diabetic mice. Diabetic animals were orally administered the aqueous extract in 500 mg/kg of body weight to assess the antidiabetic effect. The blood glucose level and body weight of the experimental animals were monitored for 4 weeks. In addition, the histopathological examination of the treated mice pancreas was also conducted to observe the changes of β-cells during the treatment process. Results The extract produced a significant decrease in blood glucose level in diabetic mice. This decrease was equivalent to that which observed in mice treated with a standard after 2–4 weeks. In addition, the plant extract exhibited a potent inhibitory effect on α-amylase and α-glucosidase activity with IC50 values of 730.15±0.25 μg/mL and 94.81±5.99 μg/mL, respectively. Moreover, the histopathologic examination of the pancreas showed a restoration of normal pancreatic islet cell architecture which observed in the diabetic mice treated with plant extract. Conclusions The aqueous A. unedo roots extract has a significant in vitro and in vivo antidiabetic effects and improves metabolic alterations. The revealed results justify its traditional medicinal use.

Abstract Qing Hao Gan Cao (QHGC), a Chinese medicinal formula containing Artemisia annua and Glycyrrhizae Radix et Rhizoma, has been used to treat sunstroke and as an antiviral agent for more than 800 years. It has not previously been subject to a toxicological safety evaluation in acute and subacute (28 days) studies. Therefore, the acute and subacute toxicity of an aqueous extract of QHGC were evaluated in vivo. For the QHGC preparation, the botanical raw materials were crushed into pieces and mixed in the ratio of 10:1 in distilled water for 12 h, then boiling three times for 2 h each time. The three decoctions were mixed and filtered, then spray-dried with hot air at 160°C for 30 min, and stored at room temperature. For the acute toxicity test, 72.0 g/kg of QHGC extract was administered by gavage to male and female mice. Body weight, general observations, and autopsy results were recorded. No mortality or toxicity signs were observed during the studies. For the subacute toxicity test, 4.0, 8.0, or 16.0 g/kg/day of QHGC extract was administered to rats for 28 days. General observations and mortality, body weight, biochemical and hematological parameters, organ weight, and pathological morphology were analyzed. The acute and subacute toxicity studies did not show significant changes in body weight, general observations, hematology and biochemical parameters, organ weight, and liver, spleen, stomach, duodenum, testis, ovary, lung, heart, and kidney histopathological analyses. The consumption of QHGC aqueous extract can be considered safe within the conditions of this study.

Background: Averrhoacarambola L., which is a folk medicine used in diabetes mellitus (DM) in ancient China, has been reported to have anti-diabetic efficacy. Aims: The aim of this study was to evaluate the hypoglycemic effect of the extract of Averrhoacarambola L. root (EACR) on the regulation of the Toll-like receptor 4 (TLR4)-Nuclear-factor kappa B (NF-κB) pathway in B) pathway in streptozotocin (STZ)-induced diabetic mice. Methods: the mice were injected with STZ (120 mg/kg body weight) via a tail vein. After 72 h, the mice with FBG = 11.1 mmol/L were confirmed as having diabetes. Subsequently, the mice were treated intragastrically with EACR (300, 600, 1200 mg/kg body weight/d) and metformin (320 mg/kg body weight/d) for 14 days. Results: As a result the serum fasting blood glucose (FBG), interleukin-6 (IL-6) and tumor necrosis factor-a (TNF-a) levels were decreased following EACR administration. Immunohistochemical analysis revealed that the pancreatic tissue expression levels of TLR4 and NF-κB were downregulated after EACR administration. EACR suppressed pancreatic mRNA expression level of TLR4 and blocked the downstream NF-κB pathway in the pancreas. According to Western blot analysis EACR suppressed pancreatic TLR4 and NF-κB protein expression levels. Histopathological examination of the pancreas showed that STZ-induced pancreas lesions were alleviated by the EACR treatment. Conclusion: These findings suggest that the modulation of the IL-6 and TNF-a inflammatory cytokines and the suppression of the TLR4-NF-κB pathway are most likely involved in the anti-hyperglycemic effect of EACR in STZ-induced diabetic mice.

Objective: Evaluation of the anti-obesity effect of aqueous extract of Mucuna pruriens seeds on rats.Methods: Male Sprague-Dawley (SD) rats were subjected to high-fat diet (HFD) for 12 wk. L-DOPA (12.5 mg/kg, p. o.) as standard drug and aqueous extract of Mucuna pruriens (AEMP) seeds (200 mg/kg, p. o. and 400 mg/kg, p. o.) as test drugs were administered in last 4 wk along with HFD. Body weight, food intake, body mass index (BMI), serum total cholesterol (TC), triglyceride (TG) and high-density lipoprotein (HDL) levels were measured at the end of fourth, eighth and twelfth wk, while white adipose tissue (WAT) mass and brain dopamine levels were measured at the end of the twelfth wk.Results: AEMP (200 mg/kg, p. o.) and (400 mg/kg, p. o.) treated groups showed a significant decrease in food intake and weight gain without altering BMI. Moreover, TG levels were lower in treated groups as compared to the HFD group, but no significant changes were observed in TC and HDL levels. L-DOPA-treated group showed a significant decrease in body weight, food intake, BMI and WAT. Both AEMP and L-DOPA-treated groups showed an increase in brain dopamine levels as compared to disease control group (p<0.05).Conclusion: L-DOPA and AEMP showed anti-obesity activity by reducing body weight gains, food intake and WAT weights; modulating TG with increased brain dopamine level which correlates to the inhibitory action of dopamine on reward mechanism.

Introduction: Hepatic diseases remain the leading cause of death worldwide. Despite overall advancements in health care, mortality due to hepatic diseases is constantly growing. More than 2 million people globally are estimated to die each year from liver diseases, and current treatment offers little for its management. Thus, it is essential to find more effective and less toxic pharmaceutical alternatives for the treatment of liver diseases. Aims & Objectives: Tamarix dioica, a shrub broadly used in herbal medicine for the treatment and prevention of various diseases. The current study was designed to analyze the hepatoprotective effect of T. dioica in BALB?cmice against CCl4-induced acute liver damage. Place and duration of study: The study was conducted in NIH, Islamabad, Pakistan, for six months in 2016-2017. Material & Methods: For in vivo evaluation, the animals (n= 42) were randomly divided into seven groups (n=6), three control (i.e. Group, I or normal control, group II or induction control received 0.9% normal saline orally, and Group III or positive control received silymarin 100 mg/kg per oral), and four treatment groups (i.e. IV, V,VI and VII were treated with oral T.dioica 200 mg/kg/day, 300mg/kg/day methanol extract, 200mg/kg/day and 300mg/kg/day of aqueous extracts respectively for six days, followed by intraperitoneal administration of CCl4 on the seventh day. The blood samples were collected for analysis of LFTs, and hepatic tissue was taken for histological analysis. Data was analyzed using SPSS version 16, one-way ANOVA with Duncan’s Multiple Range Test (DMRT). Results: CCl4 induction in Group 2 resulted in severe hepatic derangement manifested as highly elevated mean LFTs (ALT 7245.56, AST 3292.11, ALP 340.09 U/L, bilirubin 4.64 mg/dl) as compared to healthy controls (ALT 38.97, AST 50.20, ALP 57.17 U/L, bilirubin 1.25 mg/dl: (Group 1) levels p<0.001. Pretreatment with different extracts of T.dioica for 6 days before CCl4 administration produced varying degrees of hepatoprotection. 300mg/kg aqueous extract T.dioica (Group7) prevented damage with maximal hepatoprotection, reduced LFTs (ALT: 339.95 , AST: 242.90 , ALP: 116.86 U/L, bilirubin: 1.38 mg/dl) and normalized liver histology as compared to Group 2 and standard drug silymarin 100mg/kg, (ALT: 6483.23, AST: 2567.69, ALP: 272.19 U/L, bilirubin: 2.84 mg/dl: Group 3) p<0.001. Lesser hepatoprotection was provided by T.dioica aqueous extract 200mg/kg (ALT: 439.93, AST: 367.87, ALP: 180.62 U/L bilirubin: 1.53 mg/dl: Group VI) and least by 300mg/kg & 200mg/kg methanolic extracts Groups V & IV (ALT: 6338.06, 6443.91, AST: 2800.81, 3012.34, ALP: 242, 248 U/L & bilirubin: 2.82 & 3.62 mg/dl) respectively. Further, no drug-induced toxicity symptoms were observed 24 hours after administration of the high dose oral T. dioica 2000 mg/kg/body weight aqueous and methanolic extracts were administered. Conclusion: Pretreatment with T. dioica extracts especially 300mg/kg aqueous extract reduced acute CCl4-mediated liver damage, ameliorated histopathological as well as biochemical parameters and was free of toxicity in 2000mg/kg /body weight dose in the mice experimental model. T. dioica has potential in hepatoprotective drug research.

Abstract Modern treatment interventions for kidney stones are wrought with side-effects, hence the need for alternative therapies such as plant-based medicines. We have previously documented through in vitro studies that statistically optimized aqueous extract of Tribulus terrestris (Zygophyllaceae family) possesses antiurolithic and antioxidant potential. This provides strong scientific foundation to conduct in vivo efficacy and preclinical safety studies to corroborate and lend further proof to its ability to prevent and cure kidney stones. The preventive and curative urolithiatic efficacy in experimentally induced nephrolithiatic Wistar rats, along with preclinical toxicity was evaluated following oral administration of statistically optimized aqueous extract of T. terrestris. Treatment showed augmented renal function, restoration of normal renal architecture and increase in body weight. Microscopic analysis of urine revealed excretion of small sized urinary crystals, demonstrating that treatment potentially modulated the morphology of renal stones. Tissue enzymatic estimation affirmed the antioxidant efficacy of treatment with reduced free radical generation. Significant upregulation of p38MAPK at both the gene and protein level was noted in hyperoxaluric group and interestingly treatment reversed it. Acute oral toxicity study established the Median Lethal Dose (LD50) to be greater than 2000 mg/kg body weight (b.wt.) No observed adverse effect level (NOAEL) by repeated oral toxicity for 28 days at 750 mg/kg b.wt. was noted. This study lends scientific evidence to the safe, preventive and curative potential of statistically optimized aqueous extract of T. terrestris at a dose of 750 mg/kg b.wt. and suggests that the extract shows promise as a therapeutic antiurolithic agent.

Present study is to evaluate the hepatoprotective potential of methanolic extract of the plant Dolichos biflorus Linn. against paracetamol and alcohol induced hepatotoxicity in rats. Oral administration of plant extract in two doses 200mg/kg and 400mg/kg body weight were subjected for the evaluation of hepatoprotective potential against alcohol (2ml/100g) and PCM (2g/kg) induced liver injury. Silymarin (25mg/kg) was used as a standard drug. The parameters like SGPT, SGO, ALP, TB and endogenous enzymes were estimated to assess the liver functions. In addition histopathological study was also carried out. Both the lower (200mg/kg) and higher dose (400mg/kg) of D.biflorus extract showed dose dependent significant decrease in SGPT, SGOT, ALP and TB levels when compared with toxic control. Both extracts showed decrease in LPO and increase in GSH, SOD and CAT levels. Hepatoprotective effect was also confirmed by histopathological analysis of liver which showed less damage in extract treated rats. The results obtained were comparable with that of the standard. The present study concluded that Dolichos biflorus Linn. plant were found to be effective against hepatotoxicity induced by Alcohol and Paracetamol.
