Leaves of Olea europaea L. (Oleacea) are used in Tunisian folk medicine to treat many inflammation type and bacterial infections such as icterus, otitis, gingivitis and cough.The aim of this study was to investigate the chemical composition and to screen the DPPH radical-scavenging activity and the anti-inflammatory and the analgesic activities of the(More)
To determine whether the rat hindlimb elevation model can be used to study the effects of spaceflight and loss of gravitational loading on bone in the adult animal, and to examine the effects of age on bone responsiveness to mechanical loading, we studied 6-mo-old rats subjected to hindlimb elevation for up to 5 wk. Loss of weight bearing in the adult(More)
Seaweeds have caused an emerging interest in the biomedical area, mainly due to their contents of bioactive substances which show great potential as anti-inflammatory, anti-microbial, anti-viral and anti-tumoral drugs. Despite the diversity in quality and quantity of the Mediterranean Tunisian coast flora, with its large contains of marine organisms and(More)
ETHNOPHARMACOLOGICAL RELEVANCE Inflammations and immune-related diseases such as rheumatoid arthritis are growing global concerns. Most of the drugs from plants which have become important in modern medicine had a folklore origin and are traditional in systems of medicine. Citrullus colocynthis Schrad. (cucurbitaceae), endemic in Southern Tunisia, is used(More)
The present study was conducted to evaluate the antioxidant, anti-inflammatory, and antiproliferative activities of organic fractions from Cystoseira sedoides (Desfontaines) C. Agardh . Various fractions of C. sedoides (chloroform (F-CHCl3), ethyl acetate (F-AcOEt), and methanol (F-MeOH)) were screened for total phenol content, as well as antioxidant(More)
Without doubt, natural products have been, and still are, the cornerstone of the health care armamentarium. Of all natural sources, the marine environment is clearly the last great frontier for pharmaceutical and medical research. This work progresses in the direction of identifying component(s) from the Mediterranean sponge, Spongia officinalis with(More)
We report the parallel synthesis of two natural cyclopeptides, isolated from the seeds of Annona squamosa, cyclosquamosin D (A1), and Met-cherimolacyclopeptide B (B) and their analogs. All of the compounds were screened for anti-inflammatory activity by evaluating their inhibitory effects on the production of pro-inflammatory cytokines using the(More)
Olea europaea L. is used in traditional medicine in the Mediterranean areas. Its natural products are used in the treatment of different disorders, like fighting fever and some infectious diseases such as malaria, the treatment of arrhythmia, and relief of intestinal spasms. The aim of the current study is to investigate the possible anti-inflammatory and(More)
OBJECTIVES Clopidogrel, a thienopyridine antiplatelet agent, is a poor aqueous soluble compound and a P-glycoprotein (P-gp) efflux pump substrate. These two factors are responsible for its incomplete intestinal absorption. In this study, we have attempted to enhance the absorption of clopidogrel by improving its solubility and by inhibiting intestinal P-gp(More)
BACKGROUND AND OBJECTIVES Inflammations and immune-related diseases including rheumatoid arthritis are widespread in the entire globe. The treatment of these illnesses is mainly based on the use of synthetic and biotechnological drugs, in recent years. Tunisian traditional medicine is a potential source of new remedies namely Citrullus colocynthis Schrad.(More)
