This study aimed to investigate the effect of Z. multiflora hydro-alcoholic extract (ZMHE) on peptic ulcer caused by indomethacin in rats. Materials and Methods: ZMHE was prepared by maceration,  condensed by rotary evaporator and dried by a freeze-drier. In this study, 72 male Wistar rats were randomly divided into 12 groups, six in each including: normal rats, control rats, ranitidine-treated, and animals that were treated with ZMHE (100, 200, 400 mg/kg). Parenteral and oral treatments were done 1 and 2 hours, respectively before gastric ulcer induction by indomethacin (25 mg/kg, i.p.). After 6 hours, animals were sacrificed, two sides of the stomach were ligated and gastric contents and tissues were investigated in terms of pH and biochemical and histologic parameters, respectively. Results: ZMHE (at all doses) considerably decreased the ulcer area and ulcer severity in comparison to control group after oral and parenteral administration. Oral administration of this extract increased thepH of stomach contents while diminished pepsin activity in a dose-dependent manner. Following parenteral treatment, a significant difference in pH of stomach content was observed only by ZMHE 400mg/kg in comparison to control group. The myeloperoxidase (MPO) enzyme activity decreased in groups that received the extract via both oral and parenteral routes. Conclusion: It might be concluded that ZMHE could protect against experimental gastric ulcer induced by indomethacin and this action is probably mediated via reducing acid secretion and pepsin activity besides enhancing tissue antioxidant capacity}, keywords = {Zataria multiflora,Gastric ulcer,Gastric acid,Pepsin,Ulcer index}, url = {https://ajp.mums.ac.ir/article_10617.html}, eprint = {https://ajp.mums.ac.ir/article_10617_e580a089457dc067f3b1223ba3d60efd.pdf} } @article { author = {Prasanth, Rathinam and Viswanathan, Pragasam}, title = {Anti-virulence potential of eugenol-rich fraction of Syzygium aromaticum against multidrug resistant uropathogens isolated from catheterized patients}, journal = {Avicenna Journal of Phytomedicine}, volume = {8}, number = {5}, pages = {416-431}, year = {2018}, publisher = {Mashhad University of Medical Sciences}, issn = {2228-7930}, eissn = {2228-7949}, doi = {10.22038/ajp.2018.23171.1860}, abstract = {Objective: Considering the emergence of biofilm-associated pathogens with multidrug resistance, the objective(s) of the present study was to evaluate the anti-virulence property of Syzygium aromaticum extracts/fractions against 2 multidrug-resistant catheter isolates. Materials and Methods: Pulverized clove buds were subjected to bioactivity-guided isolation to identify the bioactive extract/fraction(s) with significant anti-virulence property. The clove bud powder was subjected to Soxhlet extraction and all these extracts were investigated in terms of anti-virulent efficacy using initial readout assays. Bioassay-guided partial purification was performed through column and size exclusion chromatography. Detailed testing of the anti-virulence and anti-biofilm activity of sub-minimum inhibitory concentration (sub-MIC) levels of the active fraction, was performed besides the cytotoxicity profiling in RAW 264.7 cells. Results: Gas chromatography-mass spectrometry (GC-MS) analysis of the clove bioactive fraction-2 (CBF-2), done after the bioassay-guided fractionation, revealed eugenol as the major bioactive ingredient present in CBF-2. Reduced mRNA levels of virulence factor genes after CBF-2 (700 μg/ml) treatment correlated well with the respective phenotypic assays (p<0.001). Similarly, CBF-2 (700 μg/ml) treatment exhibited significantly low mRNA levels of quorum sensing (QS) receptor genes compared to their cognate synthase genes (p<0.001). Crystal violet staining and scanning electron micrographs of CBF-2-treated biofilms showed lesser macrocolonies with remarkably simplified architecture. Cytotoxic evaluation of CBF-2 suggested a minute reduction in viability even at the highest tested concentration (1600 μg/ml, p<0.05).

Stomachache could be associated with mycobacterial infection. The present study was designed to investigate the activity of Z. acanthopodium fruits against a non-infectious Mycobacterium smegmatis and to identify the important phytochemical constituent that is toxic towards mycobacteria. Materials and Methods: The broth microdilution method was used to determine the minimal inhibitory concentration (MIC) of ethyl acetate or hexane extract of green, young fruits of Z. acanthopodium. Effect of active extract (hexane) on cell membranee integrity was studied by measuring sodium and potassium leakage into extracelullar liquid using Atomic Absorbtion Spectrophotometer (AAS). Next, cell morphology was observedby using Scanning Microscope Electron (SEM).  Column chromatography was used for fractionation and purification of  hexane extract while the chemical structure of the active compound was determined using NMR technique. Rifampicin, an antimycobacterial compound, was used as positive control. Results: Hexane extract was active against M. smegmatis with an MIC of 64 µg/ml. Plant extract at the concentration of 128 µg/ml caused ions leakage. Concentration of sodium in extracellular liquid of cells treated with plant extract was significantly higher than that of untreated cells. SEM observation revealed cell wall deformation in cultures treated with the extract. NMR spectroscopy analysis of the most active fraction revealed that the compound that exerted toxicity on M. smegmatis was geranyl acetate.

Ferula gummosa Boiss(“Barije” in Persian, from the family Apiaceae), (F. gummosa), is an extremely precious medicinal plant which naturally grows throughout the Mediterranean and Central Asia and is a native plant in Iran. The present study examined the cytotoxic effects of F. gummosa in terms of induction of apoptosis and radiosensitivity in HeLa cells. Materials and Methods: In order to determine F. gummosa cytotoxicity in HeLa cells, the cells were incubated with different concentrations of the plant resin(0-1000 µg/ml) for 24, 48 and 72 hr. Cytotoxicity was determined by MTT assay. The role of apoptosis in F. gummosa cytotoxicity was investigated using flow cytometry following propidium iodide (PI) staining of DNA. For radiosensitivity assessment, F. gummosa-treated cells were exposed to 2 Gy γ-rays, and cytotoxicity was determined in irradiated and non-irradiated (control) groups by MTT and the synergism factor was calculated. Results: F. gummosa decreased cell viability in HeLa cells in a concentration- and time-dependent manner. Flow cytometryanalysisindicated that apoptosis is involved in F. gummosa-induced cytotoxicity. Co-administration of F. gummosa and radiotherapy, showed that this plantat non-toxic low doses, could result in almost 5-fold increment in sensitization of cells towards radiation-induced toxicity. Conclusion: The concurrent use of F. gummosa and radiation increases radiosensitivity and cell death.
