the aim of our work was to compare cytotoxic and membrane-damaging effects of o. majorana l. essential oil and linalool on hep g2 and to investigate their possible protective (antioxidant) effects against h2o2 induced membrane damage. the oils were investigated by gc and gc-ms and antioxidant activity was evaluated by dpph and -carotene–linoleic acid assays. assessment of cell viability was ma...

This work aimed to determine the efficacy of the essential oil of A. gratissima as anesthetic for silver catfish, and to perform the bio-guided fractionation of essential oil aiming to isolate compounds responsible for the noted effects. Fish were submitted to anesthesia bath with essential oil, its fractions and isolated compounds to determine time of anesthetic induction and recovery. Eugenol...

Listeria monocytogenes is one of the major causes of infections in developing countries. In this study, chemical composition and anti-listerial effect of the essential oil of Zataria multiflora Boiss. alone and in combination with monolaurin were evaluated at different pH values (5, 6, and 7) and temperatures (5 ˚C and 30 ˚C). Chemical composition of Zataria multiflora Boiss. essential oil was ...

for comparison the growth characteristics and quantitative and qualitative yield of two summer savory species (such as satureja khuzestanica and s. rechingeri) in response to rainfed and irrigated conditions, an experiment was carried out on the basis of split-plot design in completely randomized block design with three replicates in north of khuzestan during growing season of 2012-2013. irriga...

Introduction: Atherothrombotic diseases such as myocardial or cerebral infarction are serious consequences of the thrombus formation in blood vessels. Thrombolytic agents are used to dissolve the already formed clots in the blood vessels. However, these drugs have certain adverse effects, which cause serious and sometimes fatal consequences.
