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...

Sideritis raeseri spp. raeseri Boiss & Heldr is a native plant from the Mediterranean region that is used due to its medicinal and culinary properties. The aim of this study was to evaluate the effects of ethanol extract of S. raeseri on the blood pressure, vascular and cardiac contractions. Arterial blood pressure was registered directly from the carotid artery in the anaesthetized rabbits. Ao...

In this contribution, the conservation status assessment of three vascular plants are presented according to IUCN categories and criteria. It includes Oryza rhizomatis D.A.Vaughan Saxifraga facchinii W.D.J.Koch at a global level Helianthemum caput-felis Boiss. regional level.

OBJECTIVE This study assessed anti-inflammatory and antioxidant activities of E. foetidum leaf extract on LPS-activated murine macrophages. METHODS RAW264.7 cells were pretreated with or without E. foetidum extract for 1 h prior to incubation with LPS for 24 h. Anti-inflammatory activity was evaluated with reference to iNOS, COX-2, TNF-α and IL-6 gene expression. In addition, NO and intracell...

The stimulatory effect of Zataria multiflora Boiss (Labiatae) and carvacrol on β-adrenoceptors was examined on guinea pig trachea. The effects of three concentrations of aqueous-ethanolic extract, carvacrol, and propranolol (β-receptor antagonist) on β-adrenoceptors were tested in nonincubated (group 1, n = 8) and incubated tracheal chains with 1 μM chlorpheniramine (histamine H1 receptor antag...

BACKGROUND AND OBJECTIVES Acinetobacter spp. are important causes of nosocomial infections. They possess various antibiotic resistance mechanisms including extended spectrum beta lactamases (ESBLs). The aim of this study was to determine antibiotic resistance profile of Acinetobacter clinical isolates especially among ESBL-producing strains and to investigate the antimicrobial effects of oleo-g...

OBJECTIVES Ferula gummosa Boiss is native to central Asia. This plant has traditionally been used in the treatment of many diseases. The antihypoxic and antioxidant activities of Ferula gummosa roots were investigated. MATERIAL AND METHODS 1,1-diphenyl-2-picryl hydrazyl radical (DPPH), nitric oxide and hydrogen peroxide scavenging activities, Fe2+ chelating ability, reducing power and hemoglo...
