objective: in the present study, the effects of aqueous saffron extract (crocus sativus l.) on the acquisition and reinstatement of morphine-induced conditioned place preference (cpp) in mice were investigated. materials and methods: subcutaneous administration of morphine (40 mg/kg for four days) produced place preference. intraperitoneal administration of aqueous extract (40 and 80 mg/kg for ...

Acetate concentration in spinach (Spinacia oleracea L.) leaf tissue has been determined by direct measurement in a leaf extract to oe 70 |xm or less. Additional evidence for such low acetate levels came from isotope dilution experiments where the [ l 14C]acetate incorporation into fatty acids was assayed using purified chloroplasts in the presence o f tissue extracts. Pyruvate dehydrogenase com...

Petroleum ether (60 degrees-80 degrees C), chloroform, acetone, ethanol, aqueous and crude hot water extracts of the whole plant of C. dactylon and the two fractions of aqueous extract were tested for antihyperglycaemic activity in glucose overloaded hyperglycemic rats and in alloxan induced diabetic model at two-dose levels, 200 and 400 mg/kg (po) respectively. The aqueous extract of C. dactyl...

objective(s) this study planned to assess antidepressant like activity of aqueous extract from leaves of citrus maxima merr. (rutaceae). materials and methods boiling was used for aqueous extraction. acute toxicity study was performed in mice. antidepressant activity was studied using locomotor activity test, modified forced swimming test (fst) and tail suspension test (tst). three doses 100, 2...

The administration of aqueous thyme extract was investigated for its hepatoprotective effect in rabbits with acute liver injury induced by a single i.p. injection of cisplatin (6.5 mg/kg). Aqueous thyme extract treatment (500 mg/kg/day, orally) was applied for 7 consecutive days, starting 4 days before cisplatin administration. Aqueous thyme extract significantly reduced serum levels of liver e...

the aqueous extract of syzygium cumini (pulp) was investigated for its possible hypoglycemic and antioxidant potentials in streptozotocin (stz) induced diabetic wistar female rats. a single intraperitoneal injection of stz at a dose of 55 mg/kg body weight elevated the glucose levels more than 230 mg/dl after 3 days. treatment with the aqueous extract of syzygium cumini (pulp) at 100 mg/kg and ...

several therapeutic effects including hypnotic, antispasmodic, treatment of abdominal and chest pain and strengthening the heart have been described for the flowers of rosa damascena. north american indian tribes use a decoction of the roots obtained from the rosa damascena plant as a cough remedy and to treat eye problem. therefore, in the present study the antitussive effect of this plant in ...

Fluorogenic RNAs that are based on the complex formed by 3,5-difluoro-4-hydroxybenzylidene imidazolinone (DFHBI) derivatives and the RNA aptamer named Spinach were used to engineer a new generation of in vitro and in vivo sensors for bioanalytics. With the resolved crystal structure of the RNA/small molecule complex, the engineering map becomes available, but comprehensive information regarding...

Acylation Mechanism, Galactolipid Synthesis The occurrence of acylgalactosylglycerol (AGG) in spinach chloroplasts is proposed. In lipid se­ parations of whole spinach leaves this fraction is hidden by variable amounts of extraplastidary steryl glucoside (SG) which depended on the physiological state of the leaf material. Beside the phospholipid fraction, this lipid mixture with unique chromato...

The activity of nitrate reductase (+Mg(2+), NR(act)) in illuminated leaves from spinach, barley and pea was 50-80% of the maximum activity (+EDTA, NR(max)). However, NR from leaves of Ricinus communis L. had a 10-fold lower NR(act), while NR(max) was similar to that in spinach leaves. The low NR(act) of Ricinus was independent of day-time and nitrate nutrition, and varied only slightly with lea...
