Inflammation plays a central role in many human diseases. Human parturition also resembles an inflammatory reaction, where progesterone (P4) and progesterone receptors (PRs) have already been demonstrated to suppress contraction-associated gene expression. In our previous studies, we have found that the progesterone actions, including progesterone-induced gene expression and progesterone's anti...

Hypersensitivity actively induced in utero is shown to persist for a longer period than passive sensitization. The degree of hypersensitivity, its duration, and its transmissibility appear to be influenced by the time elapsing between the original injection of the parent and parturition. A pregnant guinea pig receiving a parenteral injection of antigen 2 to 4 days prior to parturition transmits...

The aim of the present study was to determine changes in oxidative status plasma sows during periparturient period using markers lipid and protein peroxidation intensity. Plasma from 12 pregnant gilts collected on days 14 1 before parturition 1, 7 postpartum used study. As indicators alterations status, concentrations thiobarbituric acid reactive substances (TBARS) sulphydryl groups (SH groups)...

Parturition can be synchronized in cattle by inducing or postponing. An intramuscular injection of glucocorticoid and/or Prostaglandin F2a (PGF) induces calving within a few days after the treatment with a high incidence of retention of fetal membrane. A combined administration of a long-acting glucocorticoid and PGF improves the synchrony of partuntion, but does not reduce the incidence of ret...

The intravenous injection of a physiological dose of salmon calcitonin (0.5 microgram/kg bw) in 5 ewes on day 125 of gestation induced a slight but significant hypocalcaemia. It had no significant effect on plasma prolactin levels. Ten days after parturition the same dose of salmon calcitonin given in a similar manner to 5 ewes has no effect on suckling-induced prolactin release, although it si...
