Etude de l’activité anti-inflammatoire et antioxydant d'Artemisia campestris L et Spitzelia coronopifolia Désf dans la région d’El-oued

Abstract The purpose of this study was to evaluate the antioxidant and anti-inflammatory properties of the leaves of Artemisia campestris L and SpitzeliacoronopifoliaDésf in the laboratory as well as to study the toxicity of the ethanol extract. A phytochemical analysis of these studied plants demonstrated the presence of condensed tannins, flavonoids, phenols, and reducing sugar, which makes it possible qualitatively to determine the non-nutritive but biologically active compounds which confer flavor, color and other characteristics to the plant. Antioxidant potency was assessed by diphenyl-picryl-hydrazyl (DPPH) and anti- inflammatory activity was evaluated using the formaldehyde-induced plantar edema model. Toxicity was assessed The study of the acute toxicity of the ethanol extract showed no toxicity at 400 and 600 mg / kg PC and our extracts show less antioxidant properties.

Antihypertensive and vasorelaxant effects of aqueous extract of Artemisia campestris L. from Eastern Morocco.

Antihypertensive and vasorelaxant effects of aqueous extract of Artemisia campestris L. from Eastern Morocco.

26 The extract also revealed a positive safety profile explained by the absence of any behavioural perturbations during the 2 weeks following the administration. In our experiment, we proved the potential activity of A. campestris L. at lowering the blood pressure levels by testing the effect of AcAE on normotensive and hypertensive rats. Accordingly, the extract induced 41.1% drop of MAP of normal rats (with, 33.2% for SBP and 46.9% for DBP), at the dose of 40 mg/Kg, while the heart rate was not affected. The absence of any effect on the heart rate may lead to speculate that the hypotensive effect of AcAE is mainly mediated via a vascular pathway.

Étude de facteurs contribuant à la tolérance de cultivars de laitue à la tache bactérienne causée par Xanthomonas campestris pv. vitians

Étude de facteurs contribuant à la tolérance de cultivars de laitue à la tache bactérienne causée par Xanthomonas campestris pv. vitians

56 Stomata represent one of the most important routes for the entry of bacterial pathogens into plants (Melotto et al., 2008 ), including Xcv (Underwood et al., 2007 ). Considering the roles played by stomata in plant infection by several plant pathogens (Montillet & Hirt, 2013 ), particularly Xanthomonas (Ryan et al., 2011 ), it is possible that lettuce cultivars with higher stomatal densities could be more susceptible to BLS. Our results suggest that stomatal density may influence the resistance of lettuce to BLS. Ramos & Volin ( 1987 ) previously showed that stomatal numbers on the adaxial and abaxial leaf surfaces of tomato were correlated with the number of spot lesions produced after infection with X. campestris pv. vesicatoria. In our study, all the susceptible cultivars (VIV, CHI, GOR and PIC) had higher adaxial stomatal densities than the resistant cultivars, although the same was not always the case for the abaxial side of the leaves. Our results also show that lettuce stomatal density was generally higher on the abaxial side of the leaves than on the adaxial side. This is generally the case in most plant species (Weryszko-Chmielewska & Michałojć, 2009 ). However, no relationship could be established between stomatal area and lettuce cultivar susceptibility to Xcv. Considering that Xanthomonas cells measure 0.2–0.6 μm by 0.8–2.9 μm (Swings & Civerolo, 1993 ) and that the stomatal area on lettuce leaves varied from 110 to 263 μm 2 stomata -1 , the stomatal area does not appear as a limiting factor to bacterial penetration. Stomatal density thus emerges as a more important parameter than stomatal area in terms of the susceptibility of cultivars to BLS. In addition to stomatal density, reducing the stomatal aperture size following bacterial infection may be important in resistance, as it has been shown that a susceptible tomato accession had a greater stomatal aperture over a longer duration after Xanthomonas perforans infection than two resistant tomato accessions (Wang et al., 2017 ).

El discurso del género y del honor : Artemisia de Halicarnaso y Aminias de Palene en Herodoto

El discurso del género y del honor : Artemisia de Halicarnaso y Aminias de Palene en Herodoto

Bien, no cito acto seguido a los demás oficiales, pues no veo necesidad. Sin em- bargo, quiero mencionar a Artemisia, una mujer que tomó parte en la expedición contra Grecia y por quien siento una especial admiración, ya que ejercía perso- nalmente la tiranía (pues su marido había muerto y contaba con un hijo todavía joven), y tomó parte en la campaña, cuando nada la obligaba a hacerlo, impulsada por su bravura y arrojo. Como he dicho, se llamaba Artemisia y era hija de Lígdamis, siendo oriunda de Halicarnaso, por parte de padre, y cretense por parte de madre. Imperaba sobre Halicarnaso, Cos, Nisiro y Calidna, y aportaba cinco navíos. Precisamente, las naves que aportó eran las más celebradas de toda la flota –después, eso sí, de las de Sidón–, y, de entre todos los aliados de Jerjes, fue ella quien dio al monarca los más atinados consejos. Quiero, asimismo, puntualizar que la población de las ciudades sobre las que, como he indicado, imperaba Arte- misia, es doria en su totalidad, pues los halicarnaseos son originarios de Trecén, mientras que los demás lo son de Epidauro (VII 99; trad. C. Schrader). 18

Artemisia herba-alba anti-inflammatory activity and gastro-protective effects in mice

Artemisia herba-alba anti-inflammatory activity and gastro-protective effects in mice

This concentration decreased by 30.50 % towards the third week of treatment with the aqueous extract of Artemisia herba alba. Polynuclear production is medullary from pluripotent stem cells. Their maturation and their proliferation is controlled mainly by 2 cytokines: GM-CSF and G-CSF. There is a baseline production of PNN, which increases when needed. The maturation of the PNN requires about 5 days and the lifetime of a PNN is 2 days. Their action in inflammation is exerted via surface receptors: different chemotactic receptors (for LTB4, C5a). The activation of these receptors generates the migration of the PNN to the site of inflammation but also the production of oxygenated free radicals and the expression of adhesion molecules.

Genetic analysis of partial resistance to bacterial leaf streak ( Xanthomonas campestris pv. cerealis ) in wheat

Genetic analysis of partial resistance to bacterial leaf streak ( Xanthomonas campestris pv. cerealis ) in wheat

INTRODUCTION Bacterial leaf streak caused by various pathovars of Xanthomonas campestris is a serious worldwide bacterial disease of wheat (Boosalis, 1952; Duveil- ler, 1989). Losses attributed to bacterial leaf streak can be quite high under conditions favourable to the pathogen; up to 40% yield reductions were reported in susceptible wheat cultivars (Schaad & Forster, 1985). The disease also affects grain quality (Mehta, 1990). Bacterial leaf streak has been increasing on a world scale, and has now become one of the most important diseases of cereals (Mehta, 1990).

6 I.2. Généralités sur Artemisia herba-alba I.2.1. Description botanique Selon OUYAHYA (1987), Artemisia herba-alba est une espèce de plantes steppiques du genre Artemisia (Armoises) de la famille des Astéracées, se présente sous forme de petit chamaéphyte à tiges ligneuses très ramifiées et très feuillues, dont la hauteur varie de 30 à 80 mm (fig. 02). Les feuilles sont pubescentes, argentées, de longueur variable selon les variétés, pouvant aller de 2 à 3 mm chez les variétés communes. Les feuilles inférieures, profondément bipinnatisequées à segment terminal souvent trifide, sont pétiolées. Les feuilles supérieures ou caulinaires se réduisent de plus en plus et passent aux bractées sessiles lors de l'inflorescence. Les capitules homogènes sont groupés en grappe et en une longue panicule. Ils sont à peu près sessiles, cylindracés, petits et contenant chacun cinq fleurs hermaphrodites (QUEZEL et SANTA, 1963). Les akènes coiffés latéralement par des périanthes sont oblongs, glabres et lisses (NEGRE, 1962).

Artemisia annua, a hope for controlling the major parasitic diseases in sub-saharan Africa?

Annual wormwood (Artemisia annua L.) is a newcomer in the local pharmacopoeia. Used for over 2000 years in China to treat various diseases, its cultivation has developed on a large scale in Kenya, Tanzania, Uganda and Madagascar from the late 1990s to extract artemisinin from its tissues, a molecule particularly effective to prevent the development of protozoa vectors of malaria. Artemisinin has further anti-inflammatory and antipyretic activity and is active not only on Plasmodium falciparum, but also on many bacteria and viruses, including HIV. It has been successfully used in the disinfection of water and on certain parasitic diseases such as leishmaniasis and schistosomiasis. Finally, it has a role in the limitation of the proliferation of cancer cells.
