from flora of north west of iran, four contrasting species in term of frequency and coverage on heavy metal rich soils were selected to study physiological mechanisms for different tolerance of zn and cu toxicity in a hydroponic culture experiment. for study of zn toxicity, dactylis glomerata and secale monatum and for cu, cichorium intybus and astragalus echinops were selected. a clear differe...

A case of myiasis due to Musca domestica describes in Pseudocerastes persicus for the first time. The snake was found in Bari Karafs, Kashan, Iran, with a lesion on its body. Fourteen live larvae of M. domestica removed from its wound. This is the first report of a new larval habitat of M. domestica.

The species of Asteraceae were used traditionally in treatment of inflammatory disorders. The present study aimed to assess the anti-inflammatory effect of methanolic extract of aerial parts of Rhanterium epapposum Oliv. (R.epapposum), Achillea fragrantissima (Forssk.) Sch.Bip (A. fragrantissima), Artemisia herba-alba Asso. (A.herba-alba), Echinops spinosus L. (E. spinosus) and Echinops hussoni...

A new thiophene, echinothiophenegenol (1), together with seven known thiophenes was isolated from the crude ethanol extract of roots of Echinops grijisii Hance. The structure of 1 was elucidated on the basis of spectroscopic data. Compounds 2 and 5, isolated from the plant for the first time, and compounds 1-7 were tested for their cytotoxicity against two human cancer cell lines, HL60 and K562...

BACKGROUND In order to verify the infectivity of rodents with endoparasites in Germi (Dashte-Mogan, Ardabil Province) the current study was undertaken. METHODS Using live traps, 177 rodents were trapped during 2005-2007. In field laboratory, all rodents were bled prior to autopsy, frozen at -20°C, and shipped to the School of Public Health, Tehran University of Medical Sciences, Iran. In para...

Echinops L., es un género de Asteraceae y contiene ca. 76 especies en Irán. La investigación actual se basa seis nueve poblaciones, incluidas E. cephalotus, chorassanicus, elebursessis, leiopolycerus, ritroides robustus. frecuencia distribución quiasmas, la asociación cromosómica segregación han sido analizadas para caracteres meióticos. En las estudiadas observado irregularidades meióticas, cr...

him are Argas miniatus. Some of the adults resemble closely a photograph of Argas persicus contained in a paper by Lounsbury,8 who thinks that the two varieties are probably identical. These ticks live under the plaster of the mud-walls. If a piece be broken off and the under surface examined, ticks in all stages will probably be found, together with fragile, nearly transparent "casts or "" mou...
