BACKGROUND This study aims to determine the synergistic effects of the chemotherapeutic drug melphalan and the phytoconstituents extracted from Pinus kesiya Royle ex Gordon (Simaosong) in human cancer cells. METHODS P. kesiya twigs extracted from 50 % ethanol-water were evaluated alone (6-500 µg/mL) and in combination with melphalan (0.75-15 µg/mL). The cytotoxic effects of single extract or ...

objective(s) in the present study, the effects of aqueous-ethanolic extract from rosa damascena on heart rate and contractility were examined. materials and methods isolated guinea-pig hearts were perfused through aorta in a langendorff mode. heart rate (hr) and contractility were determined in the presence of four concentrations of the extract (0.1, 0.2, 0.4 and 1.0 mg %) and isoprenaline (1, ...

Lipopolysaccharide from Porphyromonas gingivalis (P-LPS), an important pathogenic bacterium, is closely associated with inflammatory destruction of periodontal tissues. P-LPS induces the release of cytokines and local factors from inflammatory cells, stimulates osteoclastic-cell differentiation, and causes alveolar bone resorption. However, the effect of P-LPS on osteoblastic-cell differentiati...

Background and aim: Diabetic nephropathy results from an increasing in oxidative stress. The phenolic components of mulberry (Morus nigra L.) leaves extract have antioxidant components and may modulate oxidative stress. In this study, the beneficial effects of mulberry leaves extract were assessed in diabetic nephropathy. Materials and methods: Diabetes induced by high-fat diet and injection of...

The anti-allergic of an aqueous extract of the leaves of Ailanthus excelsa Roxb.(AELAq) was evaluated by using milk induced leucocytosis and eosinophilia in mice, passive paw anaphylaxis in rats models while the anticataleptic properties was evaluated by Clonidine induced catalepsy in mice mode. The extract significantly (*p<0.05, **p< 0.01) decreased the leucocytosis and eosinophilia along wit...

The antioxidant potential of mistletoe (Viscum album L. var. coloratum Ohwi; VAL) extract in uncooked pork patties was evaluated. Three concentrations of VAL extract (0.1 [T1], 0.5% [T2] and 1.0% [T3]) along with 0.02% ascorbic acid as a positive control (V) were added to ground pork and pork patties were prepared. Incorporation of VAL extract decreased (p<0.05) the pH of the pork patties throu...

OBJECTIVES The aim of present study was to evaluate some effects of Crinum zeylanicum (C. zeylanicum) on central nervous system. MATERIALS AND METHODS C. zeylanicum methanolic bulb extract (250-1000 mg/kg orally), 2 mg chlorpromazine and 4 mg diazepam /kg body weight intraperitoneally respectively were tested in mice using Irwin test, pentobarbitone-induced sleep test, spontaneous motor activ...

conclusions these results showed an inhibitory effect for the extract of asafetida on muscarinic receptors of tracheal smooth muscle. results the ec50 obtained in the presence of higher concentration of the extract muscle was significantly higher compared to saline (p < 0.01). the maximum responses to methacholine in the presence of higher concentration of the extract (10 mg/ml) was significant...

objective(s): ischemia/reperfusion (i/r) injury of spinal cord is leading to the paraplegia observed. in this study, we investigated the protective effect of the saffron extract on spinal cord i/r injury. materials and methods: thirty five male sprague-dawley rats were divided into 5 groups: intact, sham surgery, normal saline (ns), low dose saffron aqua extract, high dose saffron aqua extract....

BACKGROUND An important role for oxidative stress, as a consequence of epileptic seizures, has been suggested. Coriandrum sativum has been shown that have antioxidant effects. Central nervous system depressant effects of C. sativum have also been reported. In this study, the effects of hydroalcoholic extract of aerial parts of the plants on brain tissues oxidative damages following seizures ind...
