Abstract Plants of Azolla caroliniana were treated with different selenium concentrations (0, 1, 2, 5, 7, 10 ppm) for seven days. Selenium (Se) content in Azolla plants increased significantly with increasing Se concentrations in the culture media up to 5 ppm. This indicated that Azolla plants were a good accumulator for Se. Selenium accumulation determined changes in Azolla biomass, doubling time and relative growth rates. Treatment of Azolla plants with low concentrations of Se (1 ppm) resulted in a significant increase in biomass. This was accompanied by a reduction in hydrogen peroxide and malondialdehyde (MDA) contents; the decrease percentages… More >

Abstract Artesunate, an antimalarial drug, has been shown to inhibit the release of inflammatory mediators in various disease conditions. The present study was carried out to evaluate the anti-edematogenic effect of artesunate in the rat paw edema model. Inflammation was induced in the hind paw of rat by sub-plantar injection of 0.1 mL of 0.5% carrageenan and the paw volume was measured up to a fixed mark just before the injection and then after 3 h. The difference in two volumes gave a measure of edema formation. At 3h the level of TNF-α, PGE2 and myeloperoxidase More >

Abstract The search for new anti-inflammatory drugs with fewer side effects than those currently available in the market has recently attracted the interest of scientists. Medicinal plants might be a natural source of medicines. Such is the case with Ziziphus amole (Sessé & Moc.) M.C. Johnst. or corongoro, a plant species native to México. It is used in traditional medicine as an anti-inflammatory drug, a healing substance and an analgesic, and in the treatment of diarrhea, diabetes, asthma and hemorrhoids. The aim of this study was to evaluate the anti-inflammatory effect of Z. amole in the acute 12-O-tetradecanoylphorbol-13-acetate… More >

Abstract In a previous work, deduced amino acid sequences from twenty wheat peroxidase genes were assigned to seven groups designated as TaPrx108 to TaPrx114. Some of these apoplastic peroxidases have previously shown to play different roles in the plant defense responses to infection by the cereal cyst nematode Heterodera avenae. In the present study, PCR marker analysis using Sears’s aneuploid wheat lines cv. ‘Chinese Spring’ was used to locate four genes encoding peroxidase isozymes. The TaPrx111-A, TaPrx112-D and TaPrx113-F genes were located on the short arm of chromosome 2B and the TaPrx109-C on the long arm of chromosome 1B. More >
