Contribution to the understanding of the stress: Studies on the response of hypophisiary PRL stress are not concluding.

Maybe the correct one is

The specificity of placntario. Identification and characterization of two major glyprotein spcies with antipeptide antibodies. Each female was subjected to a 45 min stress session, from day 4 of gestation, 3 times a week, in the morning and at variable times.

Relative concentrations of PL-II and PLP-A protein in the placenta of control and stressed rats, during the second half of gestation were estimated by immunoblotting. PLP-A concentrations in placentary tissue of rats chronically stressed were quantified.

University of Kansas Medical Center. It was incubated for 1 hour at room temperature, with the second corresponding antibody rabbit anti-IgG, prepared in goat, 1: A marker of an appropriate molecular weight was seeded on a lane of the gel and an extra run lane of homogenate that was used as negative control. One of the peripherical stress markers are the levels of catecholamines metabolites, indicators of SAM axis response.

During the days of the pregnancy studied, chronic stress did not induce any changes neither in the localization nor in placental concentrations of PL-II and PLP-A.

Changes in the hormonal concentrations of pregnant rats and their foetuses following multiple exposures to a stressor during the third trimester. PL-II participates in the signals translation to activate the receptor of pituitary PRL; these ligands are critical to maintain pregnancy during the half of pregnancy and just before delivery when a decrease of hypophisiary PRL levels takes place Soares et al, Mathias Duval on placental development in mice and rats.

We conclude that the chronic stressed mothers activated the SAM axis at the beginning of pregnancy and then they diminished the metabolites catecholamines that were interpreted as a stress adaptation coincident with normal concentrations of both placentary prolactines at this stage of the pregnancy.

No differences were evidenced neither in immunomarked cellular types nor in the immunomark intensity between the stressed rats placenta respecting those of the control ones. Data represent the corrected values of the densities obtained from 4 independent samples at a minimum and they are expressed as arbitrary unities and relativized to the control value.

The activation of the sympathetic nervous system by the corticotropin-releasing hormone CRH results in the release of noradrenaline NA from the peripheric sympathetic nervous ends. This demonstrates a rapid loss of VMA profile towards the end of pregnancy. During pregnancy by maintaining both maternal and fetal homeostasis, mammals need to reorganize their metabolism.

Placental prolactin-like protein A. The reaction was stopped in distilled water. Urinary excretion of catecholamine metabolites in hiperkinetic child syndrome. This is probably due to a habituation of the animals to the repeated stimulus. Control groups females remained in their cages until sacrifice. Tissue cuts of urn thick were deparaffinized, hydrated and H 2 0 2 treated to block endogenous peroxidase.

Sympathetic innervation reaches the adrenal medulla which releases adrenaline A in a greater proportion and also something of NA Nankova et alDe Boer et al, ; Curtin et a ; Kvetnansnky et al These antibodies were provided by Dr.

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

Some factors liberated by decidua that have not been identified yet, control the gradual declination lactogno expression of PL II and an increase of PLP-A in the bounding olacentario of rat plancenta Cambell et al. The localization of both placentary prolactines lactogenno with Cambell etal.

The mouse prolactin gene family locus. Horseman edKluwer Academic Publishers. Many of which are identical or at least, they resemble those produced by the hypothalamic-pituitary-target Jaffe, Chronic stress by immobilization IMO was applied to the experimental group females.


Pregnancy and the Prolactin Family of Hormones: Recent advance in recent progress in catecholamines under stress. E; Van Der Guten, J. Samples were suspended in sweep buffer VMA values in stressed rats at 21 days of pregnancy are smaller than the respective controls. This process lasted until their sacrifice.

Expression in the developing rat placenta. Rats were immobilized on a wooden board 20 x 20 cm by taping their four limbs to metal mounts, according to the method described Michajloskij et al The rodent possesses two placental structures: Ain, R; Canham, L. Relative concentration of PL-II of the placental homogenates on days 12, 17 and 21 of pregnancy, stressed vs. 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.

Effect of acute and repeated immobilization stress on food and water intake urine output and vasopressine changes in rats.

Biological Chemistry, 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.

Ontogeny of placental lactogen-I and placental lactogen-II. Increased plasma levels of A and NA are present in stress reaction, in order of importance, represent the stress second hormone. PL-II was staining in the trophoblast giant cells tgc cytoplasm, located at the interface between the chorioallantoic placenta and uterine deciduas, from day 12 of pregnancy rats A-B.
