BACKGROUND
Carbon tetra chloride (CCl4), an industrial solvent, is a hepatotoxic agent and it is the well established animal model for free radical-induced liver injury. The present investigation was carried out to establish the protective effect of natansnin, a novel dibenzoyl glycoside from
Antioxidative stress response of free-floating aquatic fern (Salvinia natans Linn.) was studied under increasing toxic amount of aluminium (Al) and its modulation by exogenous application of polymaine. Increased levels of superoxide (O2 (-)) and hydrogen peroxide (H2O2) species from affected tissues
Different ramets of a clonal plant exploiting a patchily metal-contaminated habitat may be exposed to different levels of toxic metals. This study investigated whether the exposure of older ("parent") ramets to Cd affected the levels of metal-binding peptides and essential elements in younger
The toxicity of arsenic (As) and the mechanisms of response to this pollutant were analyzed in two aquatic plant species, one sensitive and one tolerant to the pollutant, Salvinia minima and Lemna gibba, respectively. The plants, grown in nutrient solution at pH 6.5, were exposed to As
