The current investigation aimed to evaluate the medicinal use of  in Algeria's Bejaia region, and to examine the anti-urolithiatic, antibacterial, anti-inflammatory (), analgesic, and toxicity effects of  hydromethanolic extracts from leaves (EALE) and flowers (EALE) to give a justification for its use in the traditional medicine.

Ethnomedicinal documentation and anti-inflammatory effects of n-butanol extract and of four compounds isolated from the stems of Pituranthos scoparius: An in vitro and in vivo investigation.

Ethnopharmacological Relevance: Pituranthos scoparius is a medicinal plant belonging to the Apiaceae family. It thrives in North Africa, and is widely distributed in the high plateau of most parts of the Sahara in Algeria. This plant is widely used in the Algerian traditional medicine to treat numerous infectious diseases, dermatoses, nervous breakdowns, digestive disorders, and calm abdominal pain.

Anti-inflammatory, analgesic activity, and toxicity of Pituranthos scoparius stem extract: An ethnopharmacological study in rat and mouse models.

Ethnopharmacological Relevance: Pituranthos scoparius is a medicinal plant that is used in traditional medicine in Algeria and other North African nations to treat several diseases such as asthma, rheumatism, measles, dermatoses, jaundice, and digestive disorders.

Aim Of The Study: The present investigation was designed to investigate an ethnobotanical survey about Pituranthos scoparius in Setif region, Algeria, and assess the acute toxicity, in vivo anti-inflammatory potential and analgesic effect of Pituranthos scoparius hydromethanolic stem extract (PSSE) in rats and mice models.

Materials And Methods: Acute toxicity of PSSE was carried out based on OECD guidelines 425.

Multifunctional PLA Blends Containing Chitosan Mediated Silver Nanoparticles: Thermal, Mechanical, Antibacterial, and Degradation Properties.

Poly(lactic acid) (PLA) is one of the most commonly employed synthetic biopolymers for facing plastic waste problems. Despite its numerous strengths, its inherent brittleness, low toughness, and thermal stability, as well as a relatively slow crystallization rate represent some limiting properties when packaging is its final intended application. In the present work, silver nanoparticles obtained from a facile and green synthesis method, mediated with chitosan as a reducing and stabilizing agent, have been introduced in the oligomeric lactic acid (OLA) plasticized PLA in order to obtain nanocomposites with enhanced properties to find potential application as antibacterial food packaging materials.

Antioxidant and anti-inflammatory effect of Asphodelus microcarpus methanolic extracts.

Ethnopharmacological Relevance: Asphodelus microcarpus is an important medicinal plant belonging to family Liliaceae. This plant is used in traditional medicine to treat abscesses by local application of the powder; the roots are used against white spots, and specifically used for ear pain.

Aim Of The Study: The aim of the present study was to assess the in vitro antioxidant effects and the in vivo anti-inflammatory activity of the different parts methanolic extracts of the Asphodelus microcarpus: aerial part (APME), leaf (LME), stem flowers (SFME) and root (RME).

Chromatographic fractionation, antioxidant and antibacterial activities of Urginea maritima methanolic extract.

The present work concerns a phytochemical study of Urginea maritima L. from Algeria, and an evaluation of antioxidant activity of the methanolic extract (UMME) and its chromatographic fractions. UMME was fractionated using open glass chromatography on silica gel and antioxidant effects were evaluated using DPPH and β-carotene/linoleate assays.

Algerian propolis extracts: Chemical composition, bactericidal activity and in vitro effects on gilthead seabream innate immune responses.

Propolis has been used as a medicinal agent for centuries. The chemical composition of four propolis samples collected from four locations of the Sétif region, Algeria, using gas chromatography-mass spectrometry was determined. More than 20 compounds and from 30 to 35 compounds were identified in the aqueous and ethanolic extracts, respectively.

Antioxidant Potentials and Xanthine Oxidase Inhibitory Effect of Two Furanocoumarins Isolated from Tamus communis L.

In this investigation, the screening of two furanocoumarins; 5,8- dimethoxypsoralen (1) and heraclinin (2), isolated from the methanol root-extracts of Tamus communis L for their antioxidant activity and xanthine oxidase inhibitory effect was carried out, using different assays such as DPPH free radical scavenging effect, β- carotene / linoleic acid, xanthine oxidase (XO) inhibition and in addition to blood total antioxidant capacity. Results revealed that the two compounds have significant DPPH radical scavenging activity and effective inhibition of linoleic acid oxidation in a dose-dependent manner; 5,8-dimethoxypsoralen exhibited the highest activity with an I% = 72.69 ± 1.

Free radical scanvenging and antioxidant effects of some anthraquinone derivatives.

In this study, the screening of five anthraquinones (purpurin, xanthopurpurin, rubiadin, kermisic acid and flavokermisic acid), for their free radical scavenging and antioxidant effects was carried out, using three complementary methods. DPPH (2,2'-diphenyl-1-picrylhydrazyl) revealed that purpurin has a scavenging effect with IC50 = 3.491 ± 0.

Comparison of xanthine oxidase levels in synovial fluid from patients with rheumatoid arthritis and other joint inflammations.

Objective: To search whether xanthine oxido-reductase (XOR) present in the synovium is also liberated, to determine its activity in synovial fluid and to establish a possible relationship between XOR levels in rheumatoid arthritis (RA) and non-RA patients.

Methods: This study was carried out in the Laboratory of Immunology, University Ferhat Abbas, Setif, Algeria from 2001-2008. This study is a retrospective controlled study matching cases with RA to non rheumatoid joint inflammations.

Anti-xanthine oxidase antibodies in sera and synovial fluid of patients with rheumatoid arthritis and other joint inflammations.

Objective: To study anti-bovine milk xanthine oxidoreductase XOR antibody levels in synovial fluid as well as in serum of patients suffering from rheumatoid affections to assess a possible correlation between antibody titres and severity of disease.

Methods: Sera and synovial fluids were collected from volunteer donors at Setif University Hospital, Setif, Algeria from 2001--2007 with the consent of patients. Human IgG and IgM levels of free and bound anti-bovine milk XOR antibodies were determined using bovine XOR as antigen, with enzyme-linked immunosorbent assay ELISA.
