This paper investigates the pharmacological properties of Dichrostachys cinerea, the plant barks are traditionally used by Gabonese and Ivorian populations to treat bronchial asthma, rheumatism, and other various diseases. Although D.

Toxicity assessment and analgesic activity investigation of aqueous acetone extracts of Sida acuta Burn f . and Sida cordifolia L. (Malvaceae), medicinal plants of Burkina Faso.

Background: Sida acuta Burn f. and Sida cordifolia L. (Malvaceae) are traditionally used in Burkina Faso to treat several ailments, mainly pains, including abdominal infections and associated diseases.

Antimicrobial activity of polyphenol-rich fractions from Sida alba L. (Malvaceae) against co-trimoxazol-resistant bacteria strains.

Background: The increased resistance of microorganisms to the currently used antimicrobials has lead to the evaluation of other agents that might have antimicrobial activity. Medicinal plants are sources of phytochemicals which are able to initiate different biological activities including antimicrobials

Materials And Methods: In vitro antibacterial (MIC, MBC and time-kill studies) of polyphenol-rich fractions from Sida alba L. (Malvaceae) was assessed using ten bacteria strains (Gram-negative and Gram-positive).

Dichrostachys cinerea (L.) Wight et Arn (Mimosaceae) hydro-alcoholic extract action on the contractility of tracheal smooth muscle isolated from guinea-pig.

Background: Dichrostachys cinerea (L.) Wight et Arn. (Mimosaceae) is largely used in ethno-medically across Africa, and mainly employed for the treatment of asthma in Ivory Coast and Gabon.

Acute and subchronic oral toxicity assessment of the aqueous extract from the stem bark of Erythrina senegalensis DC (Fabaceae) in rodents.

Aim Of The Study: The decoction of the stem bark of Erythrina senegalensis (EAES) is traditionally used in the Western region of Cameroon against liver disorders. The present study evaluated the potential toxicity of this decoction after acute and sub-chronic administration in rodents.

Materials And Methods: In acute study, a single administration of EAES was given orally to mice at doses ranging from 1.

Anacardium occidentale Linn. (Anacardiaceae) stem bark extract induces hypotensive and cardio-inhibitory effects in experimental animal models.

Anacardium occidentale Linn. (Anacardiaceae) is a plant largely used in Africa for the treatment of different diseases. In Côte d'Ivoire it's commonly used for the treatment of hypertension.

Myostimulating effect of sesamum radiatum aqueous leaf extract in isolated Guinea-pig Taenia caeci contractile activity.

This study was carried to examine the effects of the aqueous leaf extract of Sesamum radiatum, a laxative plant on the contractile activity of Taenia caeci, an intestinal smooth muscle. Strips of Taenia caeci were rapidly removed from guinea-pig and were suspended between two L-shaped stainless steel hooks in a 10 ml organ bath with Mac Ewen solution. The isometric contractile force of the Taenia caeci strips were recorded by using a strain gauge.

Effects of Alchornea cordifolia on elastase and superoxide anion produced by human neutrophils.

Nitric oxide pathway-mediated relaxant effect of aqueous sesame leaves extract (Sesamum radiatum Schum. & Thonn.) in the guinea-pig isolated aorta smooth muscle.

Background: Sesamum radiatum Schum. & Thonn. (Pedaliaceae) is an annual herbaceous plant, which belongs to the family Pedaliaceae and genus Sesamum.

Nitric oxide effect on 5-hydroxytryptamine-induced vasoconstrictions of isolated smooth muscle.

The aim of the present study was to investigate a nitric oxide (NO) involvement in the mediation of a 5-HT-induced vasoconstriction response in the rat portal vein in vitro. Isolated rat portal vein segments were placed in organ baths for isometric force measurement. 5-HT (3 x 10(-8) M-3 x 10(-4) contracted portal vein preparations (EC50 = 7 x 10(-7) M) in a concentration-dependent manner.

Separation of adult chains of abnormal haemoglobin: Identification by reversed-phase high-performance liquid chromatography.

Rare abnormal haemoglobin (Hb) often poses a problem in the diagnosis of relative electrophoresis mobility. The rare neutral Hbs interact with the Hb S and thus can increase the severity of sickle cell anaemia. In the present study, we investigated the use of reversed-phase high-performance liquid chromatography (RP-HPLC) as a method for the identification of neutral or unstable Hb, and compared it with the well-known techniques urea-triton electrophoresis (UT) and isoelectrofocusing (IEF).
