recently, application of sa has increased to improve plants resistance to stresses such as drought. hence, to investigate sa effects on morphophysiological characteristics of fennel(foeniculum vulgare mill.) under drought stress, a split plot experiment based on latin square design with three replications was carried out at research farm of shahid bahonar university of kerman in 2012. three lev...

Salicylic acid (SA) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. The physiological mechanism of exogenous SA to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mM SA and then held at 25◦C up to 12 days. ...

Considerable evidence suggests that mitochondrial dysfunction contributes to the toxicity of uranyl acetate (UA), a soluble salt of depleted uranium (DU). We examined the ability of the two antioxidants, beta-glucan and butylated hydroxyl toluene (BHT), to prevent UA-induced mitochondrial dysfunction using rat-isolated kidney mitochondria. Beta-glucan (150 nM) and BHT (20 nM) attenuated UA-indu...

Effects of Pongamia pinnata, an indigenous plant used in Ayurvedic Medicine in India on the temporal variations of circulatory lipid peroxidation products and antioxidants in ammonium chloride-(AC)-induced hyperammonemic rats has been studied. Experimental rats were divided into control, AC-treated, those treated with AC + ethanolic leaf extract of P. pinnata (PPEt), and PPEt-treated. The...

Spermatozoa generate reactive oxygen species (ROS) in physiological amounts which play a role in sperm functions during sperm capacitation acrosome reaction (AR) and oocyte fusion. In addition damaged sperm are likely to be the source of ROS. The most important ROS produced by human sperm are hydrogen peroxide superoxide anion and hydroxyl radicals. Besides human seminal plasma and sperm posses...

the present work was designed to evaluate the in vitro lipid peroxidation inhibitory and antimicrobial activities of the methanol extract of phyllanthus niruri (mepn) (family:   euphorbiaceae) .   lipid peroxidation was measured by the optical density of the prepared solutions (10-320 µg/ml) and then the percent inhibition was calculated. ascorbate/feso 4 -induced peroxidation was inhibited by ...
