picrorhiza scrophulariiflora/hypersensitivity

Picroliv, a standardised iridoid glycoside fraction from the root and rhizome of Picrorhiza kurroa at a dose of 25 mg kg-1 p.o. inhibited passive cutaneous anaphylaxis in mice (82%) and rats (50-85%) and protected mast cells from degranulation (60-80%) in a concentration-dependent manner. Its effect

Picroliv, a standardised fraction from root and rhizome of Picrorhiza kurroa, consisting of iridoid glycosides and shown to be responsible for its hepatoprotective activity, was studied for immunostimulant activity. Oral administration of Picroliv (10 mg/kg x 7 days) in mice prior to immunization

The immunobiological activity was investigated of certain medicinal plants widely used in the Ayurvedic and Unani systems of medicine for treatment of chronic infections and immunological disorders. The effect of an ethanolic extract of each drug was studied on delayed type hypersensitivity, humoral

In order to explore the possible role of macrophages and other necessary immune competent (T and B) cells in the modulation of immune responses, an attempt was made to study the immunomodulatory effect of an irridoid glycoside (RLJ-NE-299A) isolated from the roots of Picrorhiza kurroa. Both in vitro

Picroliv, a standardised fraction from root and rhizome of PICRORHIZA KURROA, consisting of iridoid glycosides and shown to be responsible for its hepatoprotective activity, was studied for immunostimulant activity. Oral administration of Picroliv (10 mg/kg x 7 days) in mice prior to immunization

OBJECTIVE To study the immunomodulatory effect of ethanolic and aqueous extract of the rhizomes of Picrorrhiza kurroa (Scrophulariaceae) in normal and immunosuppressed mice models. METHODS The rhizomes extract of Picrorrhiza kurroa was administered orally according to their body weight in mice. The

A 50% ethanolic extract of Picrorhiza kurroa Royle ex Benth. (Scrophulariaceae) leaves (PKLE) was found to stimulate the cell-mediated and humoral components of the immune system as well as phagocytosis in experimental animals. PKLE elicited a dose-related increase in SRBC, induced 4 h (early) and

Four weeks pretreatment with disodium cromoglycate (DSCG) and the powdered roots of the herb Picrorhiza kurroa, Benth, rendered guinea pigs less sensitive to histamine when compared with appropriate controls. The bronchodilator effects of isoprenaline and adrenaline were found to be markedly

In the last three decades, numerous biopolymeric fractions have been isolated from medicinal plants and used as a source of therapeutic agents. The most promising biopharmacological activities of these biopolymers are their immunomodulatory effects. The biopolymeric fraction RLJ-NE-205 was isolated
