“…The role of large amounts of PGF 2α formed as the result of uterine infection and inflammation has not been well understood. It may be promptly metabolized to PGFM which has no activity on the uterus [3]. A significant rise in plasma PGFM concentrations could, therefore, be considered as an indicator of uterine infection.…”

“…The day of first ovulation was estimated to be 3 to 4 days before the first rise in A massive amount of PGF 2α is released from the cotyledon in cows around parturition [9]. PGF 2α plays an important role in the process of parturition as well as involution of the uterus postpartum and the duration of the elevated plasma concentrations of PGF 2α metabolite (PGFM) is negatively correlated with the time for uterine involution in cows [3]. This finding has encouraged the administration of PGF 2α or its analogs for the treatment of delayed uterine involution associated with endometritis in cows with dystocia and/or retained placenta.…”

“…Durante o puerpério da vaca há maciças liberações de PGF 2 (KINDAHL et al, 1992;JAINUDEEN e HAFEZ,1995), devido principalmente à elevada incidência de contaminação bacteriana (DeBOIS,1961;FREDRIKSSON et al,1988). Nos animais que vem a parir sem problemas de retenção de placenta, há inicialmente nos placentomas PGF 2 em níveis mais elevados do que nas vacas que tiveram a placenta retida (GRUNERT e BIRGEL,1982).…”

“…Existe relação linear entre a duração da liberação de prostaglandina no pós-parto e o tempo de involução uterina. Não há a possibilidade de ocorrer a ovulação pós parto, até que a liberação de PGF 2 cesse ou que esteja muito próxima dos níveis basais (KINDAHL et al,1992). Como já foi observado, a PGF 2 é liberada antes do inicio da parturição e vai acarretar a luteólise do corpo luteo gravídico pré partal, e não permitirá que os ovários iniciem a ciclicidade propriamente dita.…”
