Aim: The present study provides a scientific evaluation for the wound healing activity of methanolic extract of Ziziphus xylopyrus (Retz) Willd leaves (MEZX). Methods: Incision and excision wound models were used to evaluate the wound healing activity of MEZX on Wistar rats. In each model, animals were divided into four groups of 6 animals each. In both model, Group I was assigned as control (ointment base). Group II and III were treated with 5%w/w and 10% w/w MEZX topical ointment respectively. Group IV was treated with standard nitrofurazone ointment (0.2% w/w). The parameters recorded were percentage of wound contraction, epithelialisation period and tensile strength. Results: It was noted that the effect produced by MEZX ointment showed significant (P < 0.001) healing in all wound models when compared with the control group. All parameters such as wound contraction, epithelialisation period and tensile strength showed significant (P < 0.001) changes when compared with the control. MEZX stimulates wound contraction, decreases epithelialisation period and increases tensile strength. Conclusion: This study suggests that...

Background: Metabolic syndrome (MetS) is a defined cluster of cardiometabolic abnormalities that increases an individual’s risk of type2 diabetes (T2D) and cardiovascular disease (CVD). Heart fatty acid binding protein (H-FABP) is a major cytoplasmic low-molecular weight protein and released into the circulation when the myocardium is injured. Previous studies have demonstrated that H-FABP is closely associated with acute coronary syndrome, hypertrophic and dilated cardiomyopathy, heart failure, stroke, obstructive sleep apnea syndrome, pulmonary embolism. The aim of this study was to investigate serum H-FABP value in the patients with MetS. Methods: We measured serum H-FABP levels in 209 adult Tunisian MetS patients (108 diabetic MetS and 101 non-diabetic MetS) matched by gender and ethnic origin and 193 control subjects, using immunoturbidimetric method. All subjects underwent anthropometric and biochemical examinations. Results: Serum H-FABP levels were significantly higher in patients with MetS than in control subjects 9.80±4.75 and 3.78±1.04 ng/ml, respectively, (P<0.001). Serum H-FABP levels were significantly higher in patients with diabetic MetS than in without diabetic MetS, 12.63±4.92 and 6.77±1.80 ng/ml,...

This study was carried out with goal to predict the inhibition of Aurora Kinase B by a series of Oleocanthal by molecular modeling. During last year’s Kinases Aurora were emerged like one of the important targets of drug in several pharmaceutical companies and industries of research and it plays a main function in the regulation of the mitosis and the cytocinèse 1 and for this reason one inhibited these Kinases Aurora B with a series of oleocanthal derivatives as legand can simultaneously induce the autophagy and apoptose in the tumoral cells. To understand the complexation mechanisms in the biological system call was made at the molecular docking, we used MOE software. was optimized geometries of all ligands, in result, the calculation of the score of energy was made to form the complex and identify the interactions in the two media a solvated (water solution) and the other unsolvated in the end we find that the ligands L5 and L6 haves the lowest...

Introduction: Wrightia arborea (Apocynaceae) has been used in traditional medicine to treat ailments such as menstrual and renal complaints, snake-bites, tooth-ache and diarrhea. Objective: This study aimed to evaluate the phytochemical constituents, antioxidant, antimicrobial and antiproliferative activities of W. arborea leaf extracts. Materials and Methods: Total phenolic and flavonoid contents of the leaf extracts were determined. The antioxidant activity of the extracts were investigated using DPPH, ABTS, nitric oxide scavenging assays, phosphomolybdenum assay, reducing power and metal chelating assay. Antimicrobial activity was tested against MTCC strains and MDR clinical bacteria. The antiproliferative activity was determined using MTT assay against three cancer cell lines. Results: Extracts showed high total phenolic content ranging from 85.7± 1.15 to 40.3± 0.6 gallic acid equivalents and flavonoid content ranging from 750±5.5 to 140±3.6 quercetin equivalents per gram of dry extract. Ethyl acetate extract showed highest DPPH scavenging activity with an EC50 value of 330μg/ml. The antimicrobial effects of all the extracts were found to be genus specific – only against Klebsiella spp. The chloroform...

Aim: The study was done to evaluate the antibacterial and antifungal activity of the leaves of Colocasia esculenta Linn. Materials and Methods: Fresh tender leaves of C.esculenta collected, air-dried at room temperature, grounded to a fine powder and extracted with ethanol. The antibacterial and antifungal activity of C.esculenta compared to standard antibiotics was assessed by disc diffusion method by measuring the zone of inhibition. The organisms used for the test were Staphylococcus aureus, Klebsiella, Escherichia coli and Pseudomonas aeruginosa and Candida albicans. The agar disc diffusion method described by Kirby-Bauer was used for testing the antibacterial and antifungal activity. Results: Zone of inhibitions produced by sensitive organisms were demarcated by a circular area of clearing around plant extract impregnated discs and measured in millimeter (mm). Mean ± SEM was calculated and the data was statistically analysed by one way ANOVA followed by Dunnets multiple comparison test. Conclusion: In our study, ethanolic extract of Colocasia esculenta showed antibacterial activity against S. aureus, P. aeruginosa, E.coli, Kleibsiella and antifungal activity against...
