Background: The ethanolic extract of Pyrus communis L. fruit (EEPC) was assessed for hepatoprotective and in vitro antiradical activity against carbon tetrachloride-induced hepatotoxicity in rat’s liver. Methods: The degree of hepatoprotection was screened by measuring biochemical parameters including serum alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), total albumin (TA), total protein (TP) and total bilirubin (TB). The antiradical activity was assessed using 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydrogen peroxide and nitric oxide free radical scavenging property. The hepatoprotective effects of the extract were compared with Silymarin used as a standard drug (100 mg/kg, p.o, bodyweight). Results: The ethanolic extract of the fruit has the capabilities to scavenge the free radicals, in vitro respectively. Additionally, the ethanolic extract (200 mg/kg and 400 mg/kg, p.o, bodyweight) exhibited marked hepatoprotective action in respect of CCl4 intoxicated rodents in a dose-dependent manner. EEPC at a dose of 400mg/kg could afford significant dose-dependent protection against CCl4 induced hepatocellular injury. Conclusion: Biochemical samples obtained from the animals treated with ethanolic extracts (400mg/kg, body weight) showed a significant decrease in the levels of serum markers indicating the hepatic cell protection.

Objective: Helminthiasis is one of the most prevalent parasitic infestations worldwide posing a major threat to public health. The control of these nematodes has relied largely on the use of a limited number of anthelmintics. However, emerging resistance and side effects to the currently available anthelmintic drugs is a major concern and discovery of newer anthelmintics with a novel mode of action is the need of the hour. The present study is aimed to evaluate the anthelmintic activity of ethanolic extract of Centella asiatica Linn. (EECA) on Indian earthworms (Pheretima posthuma). Methods: The earthworms were divided into 4 groups with 6 worms in each group. The anthelmintic activity of EECA at two different concentrations (25 mg/ml and 50 mg/ml) was evaluated by assessing the time of paralysis and time of death of the worms. Albendazole was used as standard and 2% gum acacia as control. Results: Albendazole at 25 mg/ml showed the highest anthelmintic activity and had significant difference (p<0.001) with EECA at both 25 mg/ml and 50 mg/ml. Conclusion: Both doses of the test drug showed anthelmintic activity but the extract at either dose was found to be less effective than the standard drug. Further studies with higher doses of the extract should be done to evaluate the anthelmintic activity in a dose-dependent manner.

Abstract Background This study was designed to evaluate the free radical scavenging property of chloroform extract of the bark of Stereospermum chelonoides (SCBC) and to investigate its potential in Alzheimer’s disease and inflammation, two oxidative stress related disorders. Methods Preliminary phytochemical analysis and in vitro antioxidant potential of SCBC were evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay, ferric reducing antioxidant power (FRAP) assay, cupric reducing antioxidant capacity (CUPRAC) and total antioxidant capacity determination assay. Total phenol and total flavonoid contents were also determined. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) based cytotoxicity and cyto-protective assays were performed on human neuroblastoma SH-SY5Y cells. Thioflavin-T assay and caspase activation measurement assay were carried out to elucidate the mechanism of cytoprotection of SCBC observed here. In vivo anti-inflammatory potential was measured using croton oil and xylene induced ear edema tests. Results Phytochemical screening of SCBC revealed the presence of various phytoconstituents. Dose-dependent in vitro antioxidant activity was observed. The extract was enriched in flavonoids and polyphenolic compounds too. SCBC was found to inhibit amyloid-β peptide 1-42 (Aβ42) induced cell death in a dose-dependent manner. Encouraged by the cyto-protective effect, its effects on Aβ42 fibrillogenesis and caspase-3 activated apoptosis were observed. SCBC significantly slowed down the Aβ42 fibrillogenesis and caspase-3 activation in a concentration-dependent manner indicating its probable mechanism of rendering cyto-protection. SCBC has been able to reduce inflammation significantly in croton oil induced ear edema in both doses. Conclusions Thus, this study could form the basis for further study for the potential use of SCBC in oxidative stress associated cell death and inflammation.

Objective: To find out whether an isolated compound (IC) from the ethanolic extract of roots of ashwagandha prevents stress-induced hyperglycemia by direct interference with the action of increased concentration of corticosterone on hepatocytes or by preventing hyper-secretion of corticosterone or both.Methods: A group of rats served as controls, and those in another group were subjected to restraint (1 h) and forced swimming exercise (15 min), after a gap of 4 h daily for 4 w. The third group of rats received orally IC (5 mg/kg bw/rat) 1 h prior to exposure to stressors. After the last treatment period, a blood sample was collected and serum was separated for the estimation of corticosterone and glucose. In in vitro experiment, hepatocytes were treated with different concentrations of corticosterone (100, 200, 300, 400 and 500 ng/ml). In another set of experiment, hepatocytes were treated with different doses of IC (1, 10, 100, 1000 and 10 000 μg/ml of medium) along with corticosterone (400ng/ml). The concentration of glucose and activities of phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase (G6Pase) were determined after the treatment.Results: Stress exposure caused a significant increase in serum concentration of corticosterone and glucose whereas, administration of IC did not result in similar changes. Further, treatment of corticosterone in in vitro significantly increased the activities of PEPCK and G6Pase and concentration of glucose in a dose-dependent manner in hepatocytes. However, treatment with IC did not interfere with the corticosterone-induced an increase in the activities of PEPCK and G6Pase as well as the concentration of glucose in hepatocytes.Conclusion: The in vivo and in vitro results put together reveal that IC does not directly interfere with the action of corticosterone on hepatocytes. However, it prevents stress-induced hyperglycemia by suppressing hyper-secretion of corticosterone.
