background :    due to excessive consumption of synthetic drugs, drug resistance rate of pathogenic bacteria is increasing and there is an ever-increasing need to find new safe compounds to tackle this problem. this study was conducted to investigate the consequences of chavill extract on the growth and viability of gastrointestinal pathogenic bacterium and probiotics bacteria.   methods :    t...

candida species are the most common cause of opportunistic fungal infection worldwide. due to increasing resistance of fungi against conventional drugs, as well as their side effects, alternative natural products have become a renewed interest. in the current study, the anti-candida activities of scrophularia striata extract were examined. in this experimental study, microdilution assay and wel...

hydroalcoholic extract of pycnocycla spinosa was shown to have spasmolytic action in vitro and antidiarrhoeal effect in vivo . the hydroalcoholic extract of p. spinosa is composed of alkaloid, flavonoid and saponin components. alkaloid fraction of p. spinosa contains the most active constituents. therefore, the aim of this research was to separate different fractions of alkaloid extract of p. s...

nowadays, using natural preservatives than synthetic ones is increasing. the present study was aimed to compare the effect of thyme (zataria multiflora boiss), onion (allium cepa) and ziziphora clinopodioides extracts on shelf-life extending of rainbow trout (oncorhynchus mykiss) salted, vacuum packaged fillet, kept at 4°c. for this purpose fish filets were kept in 4 treatment: salted in brine ...

an experiment was conducted to investigate the effects of thyme (thymus vulgaris) and satureja (satureja khuzestanica) ethanolic extracts on the performance, blood metabolites and immune response of broiler chickens. 300 day-old ross chicks were assigned to six dietary treatments in a randomized 2 × 3 factorial block design. each treatment was given to five replicates of ten birds. variables we...

helicobacter pylori infection is one of the most common human infections which have been associated with many upper gasterointestinal complications. different treatment regimens for helicobacter pylori eradication have been used. one of these regimes is the quadruple therapy regimen which metronidazole is one of the medications. in recent years several reports on h. pylori resistance to this an...

objective in previous studies, the relaxant, anticholinergic (functional antagonism), antihistaminic and its stimulatory effects on b-adrenoceptors of nigella sativa have been demonstrated on guinea pig tracheal chains. in the present study, the relaxant effects of hydro-ethanolic, macerated aqueous (ma) and lipid-free macerated aqueous (lfma) extract of nigella sativa on tracheal chains of gui...

introduction: there are several different molecular pathways in tissue damage by ischemic brain injury. the use of antioxidants and free radical scavengers are a matter of attention by some researchers. crocus sativus (saffron) is used previously for protective effects in ischemia state by some researchers. to assess pathologic aspects of neuroprotection of saffron in some susceptible brain are...
