Milk samples were collected from 180 heifers from 20 herds around parturition to study the prevalence and persistence of intramammary infection (IMI). A total of 3382 quarter milk samples was collected each week from 4 wk before parturition to 4 wk after parturition. Staphylococcus chromogenes, the most commonly found bacterial species before parturition, was isolated from 15% of all quarters. ...

the purpose of this study is to show the effect of extraamniotic administration of corticosteroids to shorten the times to either active labor and/or delivery. this is a double blind randomized study. 65 patients who were candidates for the termination of pregnancy between the ages of 16-45, with intact membranes and unripe cervix were randomly divided into two groups, a study group (n=34) and ...

Background: The intentional commencement of cervical ripening and uterine contraction for the purpose achieving delivery prior to onset spontaneous parturition is known as induction labour. When benefits mother or foetus surpass extending pregnancy, it indicated. this study was assess efficacy a transcervical foley's catheter with extra amniotic saline infusion against intra prostaglandin E2 ge...

Platelet activation is a hallmark of severe preeclampsia, and platelet PGH synthase 1-derived (PGHS1-derived) thromboxane A(2) (TxA(2)) has been implicated in its pathogenesis. However, genetic disruption of PGHS1 delays parturition. We created hypomorphic PGHS1 (PGHS1(Neo/Neo)) mice, in which the substantial but tissue-dependent variability in the inhibition of PGHS1-derived eicosanoids achiev...

At term pregnancy in cattle and pigs progesterone is from luteal origin. Like in other domestic animal species, parturition in the cow and pig is preceeded by a sudden drop in the matemal plasma progesterone concentration. An increased Output of Prostaglandin from the pregnant uterus is most likely responsible for prepartum luteolysis. The withdrawal of progesterone is not immediately followed ...
