Although alterations are produced in the plasmatic levels of hypophisiary PRL in stressed pregnant rats, we did not find differences neither in the localization nor in the concentrations of PL-II and PLP-A in the different cellular types of placentary tissues of stressed mother.

Placental prolactin-like protein A. Plasma catecholamine and corticosterone response to predictable and unpredictable noise stress in rats.

Gestation placfntario intrauterine trophoblast cell invasion in the rat and mouse: This demonstrates a rapid loss of VMA profile towards the end of pregnancy. A statistically significant increase of VMA metabolite values was observed on day 6 of pregnancy in stressed rats respecting their controls, while on day 21 of pregnancy the values of stressed rats are significantly lower than their controls.

This is probably due to a habituation of the animals to the repeated stimulus. Each band was swept in two dimensions and specific density was corrected according to the back signal in the run lane.

Comparative developmental anatomy of the murine and human definitive placenta.

The animal was checked on the days 6, 12, 17 and 21 of pregnancy. Efficiency lacyogeno transfer was confirmed with 0. The localization of both placentary prolactines coincided with Cambell etal. VMA concentrations were determined considering the volumes of 24 h urine and the animal body weight.

To carry out the programmed sacrifice, the day after spermatozoid were detected in vaginal fluid was considered as day zero of pregnancy. Representative immunoblots, probed with antipeptide antisera specific to PL-II, in placentary homogenates on days 12, 17, 21 of pregnancy, in stressed and control rats. The rodent possesses two placental structures: The specificity of adaptation. Response of the sympathetic-adrenomedullary axis of rats subjected to stress during gestation.


On the other hand, there are receptors of high affinity to estrogen and progesterone in placentary JU which leads to presume some direct effect of these steroids on the PL II expression in this area.

Then they were rinsed in PBS, dehydrated through an alcohol ascending grades cleared in xylene and paraffine embedded. Effects of Adrenocorticotropin and Glucocorticoids.

Antpeptide antibodies reveal structural and functional characteristics of the rat placental lactogen-II.

Each female was subjected to a 45 min stress session, from day 4 of gestation, 3 times a week, in laactogeno morning and at variable times. However, Armario et al. Characterization of rat chronic mammotrophin.

Desarrollo de la placenta y lactogeno placentario by Janeth Duran Martinez on Prezi

PLP-A concentrations in placentary tissue of rats chronically stressed were quantified. This result coincides with those obtained by some other authors Cambell et al. Isolation, purification and characterization of mouse placental lactogen. This might be due either to an exhaustion of the SAM axis or to the fact that repeated expositions to chronic stress produce a decrease in A and NA liberation what is interpreted as an adaptation of the axis to this system Rodriguez, It is known that the PLP-A placenario activity is to bound to “natural killer” lymphocytes, in a specific way, in the mesometrial compartment of the uterus of pregnant rats, “natural killer” lymphocytes participle in the immune response, they increase in the half of pregnancy and then decrease at the end of this Muller Heiner Liu etal.

University of Kansas Medical Center. Many of which are identical or at least, they resemble those produced by the hypothalamic-pituitary-target Jaffe, The rats were cycled by colpocytograms in fresh to determine the estro day between Immunocytochemical analysis of PL-II with sections of placental tissue from days 12, 17 and 21 control and stressed A-F.

Maybe the correct one is

According to Fukuda et al, NA is liberated under psychological stimulus and since, LMO stress is a very strong physical stimulus, the VMA increase at the beginning of pregnancy would be a consequence of the liberation of A by the sympathetic nervous system. We experimentally used young female primipar Wistar-albino rats days of to g.


The catecholamine metabolites, 3-methoxy 4-hydroxymandelic VMA acid as well as homovanilic acid were found in animals urine. When the stimulus is repeated in a chronic way there is a decrease in catecholamines production that might be explained as a consequence of the habituation to the same stimulus Kvetnasnsky et al; Kant et al.

lactógeno placentario humano – English Translation – Word Magic Spanish-English Dictionary

Biological Chemistry, Recent advance in recent progress in catecholamines under stress. The placentraio was stopped in distilled water. Corticotropin-releasing-hormone signals adversity in both the placenta and the brain: We hypothesized that the chronic immobilization IMO stress in pregnancy rats produces alterations in prolactin concentrations in placental tissue and also changes in the response of SAM axis.

This process lasted until their sacrifice.

Two prominent regions are formed within the choriallantoic placenta: Obtention of placentary homogenates to apply immunoblot technique. One of the peripherical stress markers are the levels of catecholamines metabolites, indicators of SAM axis response.

The VMA values in stressed mothers urines increased on the day 6 respecting the control ones at the same time of pregnancy. The rats placenta synthesizes and secretes a number ofpolypeptideand steroid hormones Soares, etal, It was incubated for 1 hour at room temperature, with the second corresponding antibody rabbit anti-IgG, prepared in goat, 1: Samples were suspended in sweep buffer Relative concentration of PL-II of the placental homogenates on days 12, 17 and 21 of pregnancy, stressed vs.

Successful maturation of the mammalian embryo is largely dependent upon the functioning of a specialized extraembryonic tissue of pregnancy, the placenta.
