Ipomoea carnea fam. Convolvulaceae is a poisonous plant and its toxicity is supposed to be due to the cardiac and respiratory failure. The present paper describes the cardiac effect of aqueous extract of the fresh leaves of I. carnea using mouse and frog heart. The aqueous extract produced an initial blockade of isolated frog heart for 5-10 sec followed by dose dependent increase in both amplit...

objective: the beneficial effects of clove on toothache have been well documented. we have also previously shown the analgesic effects of clove essential oil. the present work was done to investigate the analgesic effects of the aqueous extract of clove using hot plate test. the possible role of opioid receptors in the analgesic effects of clove was also investigated using naloxone. materials a...

vitis vinifera l.is a traditional asian herb widely used for different health problems. in thepresent research, the ethanolic and the aqueous extracts of vitis vinifera l. leaves collected fromshrub, grown in tunisia, were prepared and evaluated for the antileishmanial activity againstleishmani ainfantum promastigotes. the inhibitory concentration 50 (ic50) was determined andthe results showed ...

this study was conducted to evaluate the hypoglycemic, hypocholesterolemic and antioxidant properties of mentha spicata (labiateae) leaves aqueous extract (msla) in alloxan-induced diabetic rats. in this study, hyperglycemia was induced in male rats by intraperitoneal injection of alloxan monohydrate (150 mg/kg). the aqueous extract of m. spicata was orally administered at a dose of 300 mg/kg b...

Fifteen cypress domes located within an extensively managed slash pine plantation were characterized according to the presence and nature of ditches and berms. Mean water depth and hydroperiod for the year 1978-79 were generally greater in the domes without these alterations. Cypress importance values were significantly higher in the unaltered, wet domes whereas hardwood importance values and s...

BACKGROUND The aqueous extract of Cucurbita ficifolia (C. ficifolia) fruit has demonstrated hypoglycemic effect, which may be attributed to some components in the extract. However, the major secondary metabolites in this fruit have not yet been identified and little is known about its extra-pancreatic action, in particular, on liver carbohydrate metabolism. Therefore, in addition to the isolati...

Various concentrations of aqueous leaf extract of Lantana camara were assessed in vitro conditions against second stage juveniles (J2) of Meloidogyne incognita. The standard concentration ‘S’ of leaf extract was found to be highly nematostatic, where nematodes were completely paralyzed after 12 h and after 48 h of exposure, 96% of juveniles were killed at same concentration. However, the mortal...

Collapsing factors are proteins that induce growth cone collapse and paralysis when added in a soluble form to cultured embryonic neurons. Here we examine the responses of growth cones to localized collapsing signals. Temporal retinal ganglion cell growth cones exposed to a localized collapsing stimulus from nasal retinal ganglion cell axons frequently turn smoothly away from the axons without ...

The purpose of this study was to evaluate the effects of extracts of Coptidis rhizoma, Phellodendri cortex and Gardeniae fructus, which are medicinal herbs in Orengedoku-to (Huanglin-Jie-Du-Tang in Chinese), and crocetin (a major component of Gardeniae fructus) on experimental elevation of aqueous flare in pigmented rabbits. To produce aqueous flare elevation, 0.5 microg/kg lipopolysaccharide (...

Clerodendrum umbellatum Poir (Verbenaceae) is traditionally used in Cameroon for the treatment of many diseases including intestinal helminthiasis. This study was undertaken to assess the in vivo antischistosomal activity of its leaves aqueous extract on a Schistosoma mansoni mice model and to determine the most effective dose of this extract. Mice showing a patent infection of S. mansoni were ...
