Pospectiv studies suggest that tea may protect against oxidative stress that induced tissue damage. A potential mechanism fr such effect y polyphenolc antioxidant tannic acid derived from tea was evaluated in tis study. Treatment of rats with ALCL3 for 80 days caused moderate toxicity on liver, kidney and splen as evidenced by increased LPO& No and a reduction of SOD,CAT, GST, GSH nd vitamin E.As well as histopathological changes.However improvement was noticed in the rats treated with tannic acid.

During the late pregnancy and during parturition in bovine, sevearl hormones and reoxygenation of placental tissues and consequences oxidative stress were involved. In this study blood samples from pregnant cows in the last three weeks of pregnancy were taken. At parturition 10 animals were selected as normal parturition and non-retaind placental expulsion. Other 10 cows were selected with normal parturition and retaind placenta. Another blood samples were taken after 1, 24 and 48 hours postpartum from both the obivois groups. The study concluded that oxidative stress and cortisol hormone might play an important role in the process of parturition in cows. It was also found that the extra-elevation of the LPO, NO and cortisol and the reduction of antioxidants could be used as indictor for the possibility of retention of fetal membrane after parturition.

The present study found that antioxidant and the changes in LPO and NO levels were subjected to marked changes in the course of follicular growth during luteal phase of estrous cycle in buffalo-cows. These changes in the intra-folicular environment may reflect the follicular requirements for growth, maturation and maintenance of viability of oocyte in buffalo-cows.

The study found that the use of BAL and DMPS as chelating agents after long-term of mercuric exposure resulted in considerable recovery in the histopathological, hematological. and biochemical alteration that induced by mercury. However, DMPS has a relative better effect due to its water solubility, less toxicity and its ability to chelate with more metal ions.
