Effectiveness of free radicals in hydtid cysts

ABSTRACT

Lipid peroxidation [tbars] levels of fertile cyst liquids [0.84 +/- 0.14, 0.9 +/- 0.12 mumol/L] for sheep liver and lung, respectively, were higher than infertile cyst liquids [0.29 +/- 0.07, 0.20 +/- 0.06 mumol/L] for sheep liver and lung. There were no significant differences between fertile cyst membranes [0.71 +/- 0.12, 0.74 +/- 0.27 nmol/mg wet tissue protein for liver and lung, respectively] and infertile cyst membranes [0.37 +/- 0.11, 0.39 +/- 0.15 nmol/mg wet tissue protein] in terms of tbars levels. The lipid peroxidation levels determined for protoscolices [1.99 +/- 0.45, 2.07 +/- 0.20 nmol/mg wet tissue protein for sheep liver and lung, respectively] were significantly higher than those of fertile and infertile cyst membranes. NO levels of cattle fertile hydatid liquids [liver nitrite [2.07 +/- 0.73 nmol/L], liver nitrate [4.01 +/- 1.15 mumol/L], lung nitrite [2.44 +/- 0.70 mumol/L] and lung nitrate [0.87 +/- 0.30 mumol/L]] were significantly higher compared with cattle infertile hydatid liquids [liver nitrite [0.66 +/- 0.29 mumol/L], liver nitrate [1.10 and 0.41 mumol/L], lung nitrite [0.55 +/- 0.15 mumol/L] and lung nitrate [0.54 +/- 0.16 mumol/L]]
