Three new eriophyid species (Phyllocoptinae), Shevtchenkella denticulata sp. n., Notallus pestehae sp. n. and Echinacrus ruthenicus sp. n., were described from Eryngium thyrsoideum Boiss. (Apiaceae), Pistacia vera L. (Anacardiaceae) and Lycium ruthenicum Murray (Solanaceae), respectively. All the three new species were collected from southwest of the East Azerbaijan province, Iran in 2011. It i...

The effect of aqueous-ethanolic extract of Zataria multiflora Boiss (Labiatae), on βadrenoceptors was examined on tracheal chains of guinea pigs. The effects of three concentrations of aqueous-ethanolic extract (0.05, 0.1 and 0.2 mg/mL), 10 nM propranolol, and saline on β-adrenoceptors were tested (n=8). The results showed clear leftward shifts in isoprenaline curves obtained in the presence of...
