EFFECT OF DIFFERENT VEHICLES ON HEPATO- PROTECTIVE EFFICIENCY OF DESFERRIOXAMNE IN RADIATED CARBON TETRACHLORIDE TREATED MICE

The effect of desferrioxamine (DFO) in different vehicle ( Aqueous and oily) against hepatotoxicity induced by carbon tetrachloride (CC1₄) in irradiated mice and irradiated carbon tetrachloride (IR-CCI₄) in normal mice was investigated. A single dose of CC1₄ and IR-CCI₄ (20 @/kg, i.p.) in irradiated mice (IR-mice) and normal mice induced hepatotoxicrty, manifested biochemically by significant elevation of serum enzyme activities, such as alanine trarsaminase (ALT, EC:2.6.1.2 ) and aspartate transaminase (AST, EC:2.6.1.1). Hepatotoxiaty was further evidenced by significant decrease of total sulfttydryl (-SH) content, and catalase (EC: 1.1 1.1.6) activrty in hepatic tissues and significant increase in hepatic lipid peroxidation measured as malondialdhyde (MDA). Pretreatment of normal mice and IR-mice with DFO (200 mg/kg i.p dissolved either in water or arachis oil vehicle) 1 h before CC1₄ or IR-CC1₄ injection ameliorated the hepatotoxicrty as evidenced by a significant reduction in the elevated levels of serum enzymes as well as a significant decrease in the hepatic MDA content and a significant increase in the total sulfhydryl content 24 h after CC1₄ or IR-CCI₄ administration.. These results indicated that both of oily and watery DFO can effectively ameliorated the hepatotoxicity induced by CC1₄ in IR-mice or IR-CC1₄ in normal mice. Although, the efficiency of the hepatoprotective effect of DFO in oily vehicle was higher than that DFO in aqueous vehicle. The hepatoprotective effect of DFO possibly through inhibition of the production of oxygen free radicals that cause lipid peroxidation.
