              Abstract 
 
              Aim: Evaluation of meloxicam, 
              levofloxacin, pazufloxacin, and enrofloxacin for their effect on 
              the plasma antioxidative activity (AOA) and the body weight in 
              rabbits. Materials and Methods: Thirty two male Soviet Chinchilla 
              rabbits were divided to eight groups of four rabbits each. Group 
              A, serving as control, was administered 5 % dextrose. Group B, C, 
              E and G were gavaged meloxicam, levofloxacin, pazufloxacin and 
              enrofloxacin, respectively, in 5% dextrose. Levofloxacin and 
              pazufloxacin were administered at the dose rate of 10 mg/kg body 
              weight b.i.d 12h, whereas the meloxicam and enrofloxacin were 
              administered at 0.2mg/kg body weight o.i.d and 20 mg/kg body 
              weight, respectively. Groups D, F and H were co-gavaged meloxicam 
              with levofloxacin, pazufloxacin, and enrofloxacin, respectively, 
              at the above dose rates. All these drugs were administered for 21 
              consecutive days. The plasma AOA and body weight was determined on 
              0, 7, 14, and 21 day of treatment.
 Results: The plasma AOA of meloxicam treated group was 
              significantly lower than the control from 7th day of treatment. On 
              the 14th day of treatment, the levofloxacin treated group had 
              values significantly higher than the enrofloxacin-meloxicam 
              co-treated group. Except for the levofloxacin treated group, a 
              significant decrease in the antioxidative activity was observed in 
              all treatment groups when compared to the control group on 21st 
              day of treatment. The body weight of all groups differed 
              non-significantly throughout the study period.
 Conclusion: The results from this study indicate that 
              although these drugs have no effect on the body weight, a decrease 
              in the plasma AOA is observed, especially when the duration of 
              treatment is increased.
 Key words: enrofloxacin, levofloxacin, meloxicam, 
              pazufloxacin, plasma antioxidant activity
