Kolaviron (KV), a biflavonoid fraction from the seeds of Garcinia kola has been shown to posess antiinflammatory properties in animal models of inflammation. In this study, the effect of KV on carrageenan-induced paw edema was investigated in mice. Furthermore, the effects of KV on the production of the pro-inflammatory mediators- nitric oxide (NO) and(More)
Anti-ulcer potential and proton pump inhibitory activity of kolaviron (KV) isolated from Garcinia kola Heckel has been evaluated using different ulcer models. Cold-restraint (CRU), aspirin (ASP), alcohol (AL), pyloric ligation (PL) induced gastric ulcer models were used to assess anti-ulcerogenic activity of KV in rats. Effects of KV on gastric juice for(More)
Kolaviron is a mixture of biflavonoids found in the nut of the West African edible seed Garcinia kola, and it has been reported to exhibit a wide range of pharmacological activities. In this study, we investigated the effects of kolaviron in neuroinflammation. The effects of kolaviron on the expression of nitric oxide/inducible nitric oxide synthase (iNOS),(More)
In continuation of our drug discovery program on Indian medicinal plants, the gastro protective mechanism of chebulinic acid isolated from Terminalia chebula fruit was investigated. Chebulinic acid was evaluated against cold restraint (CRU), aspirin (AS), alcohol (AL) and pyloric ligation (PL) induced gastric ulcer models in rats. Potential anti-ulcer(More)
BACKGROUND The present study was undertaken to evaluate the anti-ulcer and antioxidant activities of the ethanol extract of Lagenaria breviflora (EELB) whole fruit in laboratory rats. METHODS The anti-ulcer property of the ethanolic extract of the whole fruit of Lagenaria breviflora (LB) was assessed using the cold-restraint stress-induced (CRU) gastric(More)
The present study was conducted to evaluate the anti-nociceptive and anti-inflammatory properties of an ethanol extract of whole fruit of Lagenaria breviflora (LB) in rat and mice. Analgesic activity was measured by hot plate, formalin-induced paw licking, and acetic acid-induced abdominal writhing tests, while anti-inflammatory activity was determined by(More)
BACKGROUND & OBJECTIVE Hedranthera barteri (HB) is used in folk medicine as a vermifuge, laxative and an anti-inflammatory agent. The aim of this study was to evaluate the anti-ulcer and antioxidant properties of the dichloromethane fraction of HB root (DMHBR). METHODS Anti-ulcerogenic activity was assessed in cold-restraint (CRU), aspirin (ASP), alcohol(More)
In this study, the effects of ethanol extract of Ocimum gratissimum (EEOG) on both basal and stimulated gastric acid secretion and gastric mucus secretion were investigated in Albino rats treated with the extract. Four groups of animals were used. Sub-group 1A serves as control. Animals in Group 2A, 3B and 4B were pretreated with 200 mg/kg of (E3EOG) for 1,(More)
Hedranthera barteri, anti-inflammatory activity, anti-nociceptive activity, anti-histaminic activityL. (HB) is used in the treatment of painful conditions and oedema amongst its folkloric use. The hexane and ethyl acetate fractions of the root of H. barteri were investigated for anti-nociceptive and antiinflammatory properties and probable mechanism of(More)
BACKGROUND Ethanolic leaf extract of Cnidoscolus aconitifolius was evaluated for analgesic and anti-inflammatory activities. METHODS The analgesic activity of the extract was assayed by the formalin-induced paw licking test, acetic acid-induced abdominal writhing and hot plate test, whereas its anti-inflammatory activity was determined by its effects on(More)
