Effect of Ligaria cuneifolia catechin- and quercetin-enriched fractions on hemorheology and plasma cholesterol

Clinical Hemorheology and Microcirculation, 2010
We tested the in vivo and the in vitro effects of both Ligaria cuneifolia catechin- and quercetin-enriched fractions on erythrocyte shape and deformability, and on plasma cholesterol level. For in vivo studies, adult male Wistar rats were randomized in three experimental groups which received intraperitoneally, once a day, 3 days: Control: saline ...

Nectar secretion pattern, removal effects, and breeding system ofLigaria cuneifolia(Loranthaceae)

Canadian Journal of Botany, 1996
Some aspects of the reproductive biology of Ligaria cuneifolia have been studied, addressing the following questions: (i) Are there temporal differences in the female and male functions? (ii) How do nectar composition, volume, concentration, and amount of sugar vary throughout the flower lifetime? (iii) How does the plant respond to nectar removal? (iv)

Host Response and Endophyte Structure of the MistletoeLigaria cuneifolia(Loranthaceae) ParasitizingCorryocactus brevistylus(Cactaceae)

Haseltonia, 2015
Abstract: Parasitic plants must be adapted to their hosts, and hosts must have ineffective defenses. Two xeric adaptations in cacti—a broad nutrient-poor cortex and a tough hypodermis—probably are effective defenses. However, Ligaria cuneifolia overcomes these defenses with unusual methods of attack and endophytic growth, although the host ...

Estudio farmacológico de un agente vasoactivo presente en Ligaria cuneifolia var. cuneifolia

1994
The pressor effect of infusions (6.25-25%) from Ligaria cuneifolia var. cuneifolia was studied by intravenous injection in conscious rats. A vasoactive agent with pressor and hypotensive effect was detected. The pressor effect could be mediated by a direct stimulation of α-adrenoceptors. The hypotensive effect was seen after an α-adrenoceptor blockade.

Hemorrheologic changes induced by aqueous extract of Ligaria cuneifolia: treatment by two different administration routes.

Clinical hemorheology and microcirculation, 2005
Ligaria cuneifolia (R. et P.) Tiegh. (Loranthaceae) (Argentine mistletoe) is usually used in local folk medicine. This work focuses on the hemorrheologic parameters in the treatment with an aqueous extract of Ligaria cuneifolia (Lc) by two different administration routes: intraperitoneal (i.p.) and intravenous (i.v.).

Importancia toxicológica de la presencia de sustancias aminadas en ejemplares de Ligaria cuneifolia var. cuneifolia colectados en diferentes areas de la República Argentina

1989
Se analizaron 31 ejemplares de Ligaria cuneifoíia var. cuneifolia utilizando cromatografía en capa fina. Se detectó la presencia de tiramina, ácido gammaaminobutírico (GABA) y otros productos aminados no identificados. Se compararon los diferentes ejemplares en función de sus mapas cromatográficos.

Effect of the vehicle polyvinylpyrolidone and the Methanolic Fraction of Ligaria cuneifolia (Argentine Mistletoe) extract on hemorheological properties and biliary secretion in rats.

Clinical hemorheology and microcirculation, 2007
Ligaria cuneifolia (R et P) Tiegh. (Loranthaceae) (Lc) aqueous extract-treated rats by via intraperitoneal (i.p.) show increased blood viscosity and decreased plasma cholesterol (Chol) levels. In this work, we analize the effect of the vehicle polyvinylpyrrolidone (PVP) and that of the Methanolic Fraction of the extract of Lc (MFLc) on hemorrheological

Anatomía foliar y caulinar comparativa de la "Liga" [Ligaria cuneifolia (R. et P.) Tiegh.] y la "Liga Blanca" [Tripodanthusflagellaris (Cham. et Schlecht.) Tiegh.]

1998
Se realizan estudios anatómicos comparativos de tallos y hojas de la "liga" [Ligaria cuneifolia (R. et P.) Tiegh.] y la "liga blanca" [Tripodanthus flagellaris (Cliam. et Schlecht.) Tiegh.], pertenecientes a la familia Loranthaceae. La primera se utiliza en medicina popular en Argentina para el tratamiento de la hipertensión.
