The photoreduction of cytochrome c by spinach chloroplasts has been noted by several investigators (12, 20, 25). In a preliminary report, we have presented evidence that aqueous digitonin extracts of spinach chloroplasts contain a cytochrome c photooxidase (22) which appears to be similar to the photooxidase present in extracts of photosynthetic bacteria studied by Kamen and Vernon (13, 14, 32)...

Background: Restraint stress causes inflammation in nervous system that leads to emersion of neurodegenerative diseases. Spinach (Spinacia oleracea L.) contains different agents with antioxidant, antiapoptosis, and hepatoprotective properties. This study examined the effect of spinach hydroalcoholic extract (SHE) on TNF-α and IL-1β expression in hippocampus of male Wistar rats exposed to chroni...

Glycoglycerolipids are mostly found in plants, however the beneficial effects of the glycoglycerolipids on mammalian body have not been understood. In this study, we investigated the effects of glycolipid extracts from spinach, which highly contained glycoglycerolipids, on mucosal injury induced by 5-fluorouracil (5-FU) in rats. Preadministration of glycolipid extracts from spinach (20 mg/kg bo...

the aim of this study was to assess the efficacy and tolerability of the aqueous extract of echium amoenum in combination with ssris in patients with general anxiety disorder (gad). the study was an 8-week double-blind randomized clinical trial. thirty-seven adult outpatients who met the dsm-iv-tr criteria for gad based on the structured clinical interview participated in the trial. in this stu...

preliminary studies revealed that urtica dioica has been known as a plant that decrease blood glucose. despite the importance of this plant in herbal medicine, relatively little research has been down on effects of this plant on islets yet. the objective of the current study was to evaluate the effect of dried urtica dioica leaf alcoholic and aqueous extracts on the number and the diameter of t...

background : the study was aimed to show the effect of molecular mechanism of aqueous garlic extract (age) on expression of ifnγ and inos genes in leishmania major . methods : leishmania major promastigotes (mrho/ir/75/er) were added to the in-vitro cultured j774 cell line, the cells were incubated for 72 hours. various concentrations of garlic extract (9.25, 18.5, 37, 74, 148 mg/ml) were added...

background: teucrium polium has been known as an important traditional medicinal plant and is used for different therapeutic purposes such as gastrointestinal disorders. therefore, the anti-spasmodic and antinociceptive activities of aqueous extract of teucrium polium w as examined. methods: anti-spasmodic effect of different concentrations (47-470 mg/l) of teucrium polium extract was assessed ...

abstract recently weed scientist are more interested in weed management by allelopathy . the main objective of the study was to evaluate allelopathic potential of sunflower on redroot pigweed and common lambsquarter. this study was conducted in two series of laboratory and greenhouse experiments. under laboratory conditions, leaf, stem and root aqueous extracts of sunflower at 0%, 2.5%, 5%, 7.5...
