Some Dorema species are used in Persian traditional medicine. In the present study the total extract from the roots of Dorema hyrcanum Koso-Pol. was investigated for its in-vitro (pLDH assay) and in-vivo (Peters' 4-days suppressive test) antiplasmodial effects and assessed for cytotoxicity against the normal cell line MDBK (MTT test). The IC50 values for a chloroquine- sensitive (3D7) and a chl...

Production of methane in the hindgut of the cockroach Periplaneta americana was found to vary, depending on the feeding regimen. Methane production was positively correlated with the numbers of the ciliate Nyctotherus ovalis living in the cockroach hindgut. Defaunation of the cockroaches by means of low concentrations of metronidazole (Flagyl) resulted in a quick drop of methane production. Add...

In this study was aimed to determine the genotoxic effect of Ramalina farinacea lichen species against stress sources at molecular level. After applying three different heavy metals (Pb2+, Cd2+, and Cr6+) R. farinacea, extent which sample absorbed these determined by Flame Atomic Absorption Spectroscopy. RAPD MSAP-AFLP assays were also used status DNA damage. The metal analysis showed that had ...

In vitro, the photoprotective, cytotoxic and photomodifying properties of hexane benzene extracts from widely distributed in Belarus lichens Cladonia arbuscula, Evernia prunastri, Hypogymnia physodes, Ramalina pollinaria Xanthoria parietina culture human keratinocytes (HaCAT), are estimated. It was found that these not they have a effect upon irradiation keratinocyte cultures with ultraviolet l...
