Identification and characterization of two major glyprotein spcies with antipeptide antibodies. To carry out the programmed sacrifice, the day after spermatozoid were detected in vaginal fluid was considered as day zero of pregnancy. Neither concentrations of PL-II nor the PLP-A concentrations showed alterations in placentary tissue of rats subjected to chronic IMO stress at the three stages of pregnancy studied when they were compared with their respective controls.

The reaction was stopped in distilled water.

PL-II immunomarkation was localized in the cytoplasm of the giant trophoblastic cells in the decidua region associate to placentary tissue in both groups the control and stressed rats at day 12 of pregnancy Fig.

E; Van Der Guten, J. VMA is produced as metabolite of both A as well as NA from the sympathetic nervous system, central and peripheric and from the adrenal gland Amam, et al. This is probably due to a habituation of the animals to the repeated stimulus.

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. Expression in the developing rat placenta.

This demonstrates a rapid loss of VMA profile towards the end of pregnancy. Response of anterior pituitary hormones to chronic stress.

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. 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.

We experimentally used young female primipar Wistar-albino rats days of to g. Williams et al, did not find any variations in the levels of maternal PRL in stressed rats when applying LMO chronic stress and accute stress by means of several stressors.

Two prominent regions are formed within the choriallantoic placenta: 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.

Four differentiated trophoblast cell phenotypes comprising the rat chorioallantoic placenta can be readily identified: 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 lactkgeno. 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.

Effects of regulatory of exposure to chronic immobilization stress on the circadian pattern of pituitary adrenal hormones, growth hormone and thyroid stimulation hormone in the adults male rat. The placenta obtained at days 12,17, and 21 placentqrio of pregnancy were fixed in phosphate buffer PBS, pH 7.

Immunocytochemical analysis of PL-II with sections of placental tissue from days 12, 17 and 21 control and stressed A-F. Considering our results of the SAM axis response to the chronic stress effects in pregnant rats, we may conclude that a SAM axis profile decay is produced.

One of the peripherical stress markers are the levels of catecholamines metabolites, indicators of SAM axis response. Hypoactivity of thehypothalamo-pituitary-adrenocortical axis during revovery fron chronic variable stress.

Maybe the correct one is

Time-related changes and adaptatin. This might be due either to an exhaustion of the SAM axis or to the fact that repeated expositions to lactoogeno stress produce a decrease in A and NA liberation what is interpreted as an adaptation of the axis to this system Rodriguez, The rats placenta synthesizes and secretes a number ofpolypeptideand steroid hormones Soares, etal, Relative concentration of PL-II of the placental homogenates on days 12, 17 and 21 of pregnancy, stressed vs.

Three rinses with TBS-T were then done the first one for 15 min and the other two for 5 min. Besides, the fetectomy reduces PL II levels in maternal serum in the second stage of gestation Cambell et al.

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

Effect of acute and repeated immobilization stress on food and water intake urine output and vasopressine changes in rats. Homogenates were centrifuged in the cold at X g for 15 min. Direct evidence for chronic stress-induced facilitation of the adrenocorticotropin response to a novel acute stressor.

Pregnant females were separated in two groups: PL-II participates in the signals translation to activate the receptor of pituitary PRL; these ligands are llacentario to maintain pregnancy during the half of pregnancy and just before delivery when a decrease of hypophisiary PRL levels takes place Soares lactogenl al, Trophoblast giant cells and spongiotrophoblast cells represent endocrine cells of the rat placenta which belong to prolactines PRL family Soares, et al, ,
