The in vitro effects of four different species of arsenic (arsenate, arsenite, monomethylarsonic acid, and dimethylarsinic acid) in mobilizing iron from horse spleen ferritin under aerobic and anaerobic conditions were investigated. Dimethylarsinic acid (DMA(V)) and dimethylarsinous acid (DMA(III)) significantly released iron from horse spleen ferritin(More)
Adult female B6C3F1 mice were given 720 mg/kg of DMA by oral gavage at one of three times (2 h, 15 h, or at both 21 and 4 h) before sacrifice. Significant (P < 0.05) decreases in liver GSH and GSSG contents (15-37%) were observed. Some evidence of DMA-induced hepatic DNA damage (at the P < 0.10 level only) was observed. Pulmonary and hepatic ODC activities(More)
AIM OF THE STUDY To systematically investigate the anticonvulsant activity of methanol extract of Benkara malabarica roots and to provide a biochemical basis elucidating its mode of action. METHODS The median lethal dose (LD(50)) of Benkara malabarica extract was determined. The anticonvulsant activity of the extract was assessed in strychnine-induced and(More)
The cessation of eating under normal physiological conditions is a voluntary act induced by a conscious sensation known as satiety. In pathological situations there is loss of appetite or anorexia. We have been able to isolate and characterize a proteoglycan from membranes of mono- and dicotyledonous plant sprouts which reduced the food intake significantly(More)
