Aims: The aim of the study was to assess the antibacterial effect of Ficus carica extracts against Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, & Staphylococcus aureus. Study Design: Evaluation of antimicrobial activity using Cup-cut agar method. Place and Duration of Study: Microbiology Research Laboratory, Department of Microbiology and Immunology, Faculty of Pharmacy, University of Tripoli, from October 2015 to March 2016. Methodology: The leaves and stem part extracts of Ficus carica plant were prepared using maceration method. The antibacterial activities of the extracts were evaluated using Cup-cut agar method to determinate inhibitory zone diameters in millimeters of the plant extracts against Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa. The measurement of exponential bacterial growth curves was used to determine the type of growth pattern spectrophotometrically at 600 nm. Furthermore, plate count methods were also used to enumerate the bacterial count and to determine the percentage of inhibition as well as IC50. Results: The results of this study showed that Ficus carica extracts used, exhibited antimicrobial activity against Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Staphylococcus aureus. The maximum zone of inhibition against S. aureus (27± 0.04mm, p

The anti-ulcer activity of the oil and mucilage obtained from flaxseed (Linum usitatissimum) was evaluated in a rat model of ethanol-induced gastric ulcer. Our results show that pretreatment of rats with flaxseed oil and flaxseed mucilage significantly reduced the number and length of gastric ulcers induced by ethanol. Flaxseed oil was more effective than flaxseed mucilage in reducing the number of ulcers. The reduction in ulcer severity (cumulative length in mm) provided by an oral dose of flaxseed oil (5 ml/kg) was more prominent than that obtained by ranitidine (50 mg/kg). This study indicates that both flaxseed oil and flaxseed mucilage can provide a cytoprotective effect against ethanol-induced gastric ulcers in rats. arabic 19 English 94

Grape seeds extract has therapeutic values including antimicrobial activity, antioxidant effect, wound healing and prevention of cardiovascular diseases. This study aimed to evaluate and compare antibacterial activity of different species of grape seed) Vitis labrusca, Vitis vinifera and Vitis vinifera( against some bacterial strains (Staphylococcus aureus, Streptococcus pneumonia, Acinetobacter Calcoaceticus, Klebsiella pneumoniae and Escherichia coli). Determine antioxidant effect of grape seed extracts (qualitatively). Antibacterial effects was performed using agar cup cut diffusion method for all bacterial species, followed by using minimum inhibitory concentration MIC for the species showed to be inhibited by grape seeds extracts. Antioxidant assay was done using DPPH scavenging test, methanolic solution of each grape seeds was spotted on TLC paper, sprayed with 0.2 % methanolic solution of diphenyl picryl hydrazyl (DPPH) reagent. Vitamin C was used as positive control. From the results, all grape species didn’t have any effect on K. pneumonia and E. coli, red and black grape seeds showed the highest inhibition zone (20 mm) on Staph. Aureus agar plate, green grape had the highest effect on Sterp. Pneumonia agar plate (20 mm). The lowest effect was for the red grape seeds extract (13 mm) on Acinetobacter calciaceticus. In general the three grape seeds extract had effect on Staph. aureus, Sterp. pneumonia and Acinetobacter calciaceticus. The red and black grape seed extract was effective against Sterp. pneumonia strain at MIC values of 7.8 mg/mL and black grape seeds extract had MIC at 7.8 mg/mL on Staph. aureus. However, the test for MIC of seeds extracts for the rest of bacterial species ranged between 15.62 and 87.5 mg/mL. The result showed that black grape seeds extract had the largest spot change in color indicating strong antioxidant effect. The lowest effect was by red grape seeds. From this result black grape showed to be the best grape seeds extract among the three chosen species in its antibacterial and antioxidant efficacy.
