Comparación de las funciones yoicas de realidad y el potencial suicida entre los descendientes de migrados internos y externos / Comparison of the ego functions of reality and the suicidal potential between the descendants of migrated internal and external

La presente comunicación se enmarca dentro de la investigación: "El factor transgeneracional en las migraciones: Su efecto en el aparato psíquico" (UBACyT 2014-2017), dirigida por la Dra. Viviana Vega. La migración es una experiencia potencialmente traumática que configura con frecuencia una situación de crisis. Se parte del supuesto de que cuando el sujeto no logra elaborar adecuadamente dicha vivencia la transmite a las generaciones subsiguientes a modo de trauma no resuelto. El objetivo de este trabajo es evaluar el Potencial Suicida y las Funciones Yoicas de Realidad en los descendientes de migrados internos y externos. Se trata de un estudio descriptivo, cuyos participantes han sido 50 sujetos descendientes de migrados (20 sujetos descendientes de migrados internos y 30 sujetos descendientes de migrados externos). Los instrumentos utilizados fueron el Psicodiagnóstico de Rorschach administrado a partir de los lineamientos de la Escuela Argentina y la aplicación de las Escalas E.S.P.A (Escala de Potencial Suicida Para Adultos) y E.F.Y.R (Escala de Funciones Yoicas de Realidad).Se ha podido comprobar en los protocolos analizados que en los descendientes de migrados externos, el compromiso en el Potencial Autodestructivo (E.S.P.A) y en las Funciones Yoicas de Realidad es mayor respecto de los descendientes de migrados internos. El alcance de la migración externa adquiere otra magnitud, y en consecuencia, es posible concluir que, en términos generales, las pérdidas no dueladas, lo traumático, lo desmentido y repudiado en una generación, puedan llegar a trasmitirse a las generaciones siguientes bajo el sesgo de la compulsión a la repetición y la pérdida de la capacidad representativa de la psique.

This communication is part of the research: "transgenerational factor in migration: its effect on the psychic apparatus" (UBACyT 2014-2017), directed by Dr. Viviana Vega. Migration is a potentially traumatic experience that often sets up a crisis situation. When the subject fails to prop-erly develop this experience transmits it to subsequent-generations as unresolved trauma mode. The objective of this work is to evaluate the suicide potential and the ego functions ofreality.to descendants migrated internal and external. It is a descriptive study, whose participants are 50 descendants migrated (20 subjects descendants migrated internally and 30 subjects descendants migrated external). The instruments used are the Rorschach Psychodiagnostic administered from the Argentina School guidelines and the application of the scales (Scale of Potential Suicide for Adults) E.S.P.A and E.F.Y.R (Scale of Ego Functions of Reality). It has seen analyzed protocols that on the descendants of migrated external commitment in the self-destructive potential and the Ego Functions of Reality are greater with respect to the descendants of migrated internally. It is has been proven tested protocols that on the descendants of migrated external, the commitment in the self-destructive potential (E.S.P.A) and the Ego Functions of Reality is greater with respect to the descendants of migrated internally. The scope of external migration acquires another magnitude, and as a result, it is possible to conclude that, in general terms, the losses not dueladas, the traumatic, it debunked and repudiated in a generation, to reach transmitted to the following generations under compulsion to repetition bias and the loss of the ability of the psyche.

Efecto biológico de la hipertermia hídrica controlada sobre hueso sano de conejos / Biological effect of controlled fluid hyperthermia on rabbit healthy bones

La hipertermia hídrica se ha utilizado para tratamientos de diversas formas de cáncer, en hueso aún no se ha determinado cuál es su efecto; se realizó este estudio prospectivo para demostrar los cambios estructurales y metabólicos y los efectos en la consolidación de hueso expuesto a hipertermia hídrica. Se utilizaron 30 conejos de raza New-Zealand. Con peso entre 2.8 y 3.2 kg divididos en 9 grupos y 3 subgrupos, se realizó osteotomía en el tercio medio del fémur derecho; este segmento fue expuesto a hipertermia a 15, 20 y 25 grados centígrados, durante 50, 60 y 70 minutos, gammagrafía ósea cada cuatro semanas y radiográficos cada semana hasta la semana 13. Para el análisis estadístico se utilizó la prueba de post-hoc y test de Tukey, encontrando diferencias en las concentraciones de elementos químicos a temperaturas superiores a 60 grados durante 20 minutos con significancia estadística, retardo en la consolidación y evidencia de actividad metabólica. Se concluye que con la exposición a temperaturas de 60 grados durante 20 minutos se presentaron alteraciones morfológicas en potasio, magnesio, azufre y fósforo y retardo en la consolidación ósea. Estos resultados son usados como parámetros para el tratamiento con hipertermia hídrica controlada en tumores óseos.

Fluid hyperthermia has been used to treat various types of cancers, but its effects on bone have not been determined. The purpose of this prospective study was to show the structural and metabolic changes of bone exposed to fluid hyperthermia and the effects of the latter on bone healing. Thirty New Zealand rabbits were used, weighting 2.8-3.2 kg; they were divided into 9 groups and 3 subgroups. An osteotomy was performed in the mid third of the right femur and this segment was exposed to hyperthermia at 15, 20 and 25 degrees centigrade for 50, 60 and 70 minutes. A bone scan was performed every 4 weeks and X-rays were taken every week up to week 13. The post-hoc Tukey test was used for the statistical analysis. Differences were found in the concentration of chemicals at temperatures above 60 degrees for 20 minutes with statistical significance; bone healing was delayed and there was evidence of metabolic activity. We conclude that exposure to temperatures above 60 degrees for 20 minutes resulted in morphologic alterations in potassium, magnesium, sulfur and phosphorus, and delayed bone healing. These results are used as parameters for the treatment of bone tumors with fluid hyperthermia.

Intrahost distribution and trasmission of a new species of cyclopoid copepod endosymbiotic to a freshwater snail, Pomacea canaliculata (Caenogastropoda, Ampullariidae), from Argentina

A new species of cyclopoid copepod, Ozmana huarpium, is described as a symbiont to Pomacea canaliculata (Lamarck 1822) (Caenogastropoda, Ampullariidae). Rather large numbers (about one hundred copepods per snail)were found, althought there was no evidence of harm to the host. To our knowledge, O. haemophila (symbiont to P. maculata), and the currently described species, O. huarpium, are the only copepod species ever recorded as endosymbionts to freshwater invertebrates. While O. haemophila is restricted to the haemocoel of its host, O. harpium predominate in the penis sheath, the ctenidium and the mantle cavity, figuring in these pallial organs 63-65 por ciento of total mature forms. The sex ratio of the symbiont is skewed to the female side in these organs, specially in male hosts. The hypothesis that a special female tropism for the male host´s pallial organs might ensure interindividual transmission of the symbiont was tested, with indications that the symbiont is mainly transmitted during copulation.

Inhibin binding sites in bovine pituitary membranes

Membranes derived from bovine pituitary glands free of the neural lobe were used to investigate the presence of binding sites for inhibin, a glycoprotein produced by the ovarian granulosa cells capable of selectively suppressing FSH secretion from the pituitary gland. Optimal concentration of membranes (400 micrograms prot) and 125I-bovine inhibin (2 nM) were incubated in a medium containing 50 mM Tris-HCl pH 7.4, 0.01 M MgCl2 and BSA 0.01 percent in a final assay volume of 200 microliters at 37 degrees C for different time intervals. Non-specific binding was estimated using unlabelled inhibin in excess. The time course of specific 125I-bovine inhibin (2 nM) binding to bovine pituitary membranes is slow with 50 percent binding at approximately 20 min of incubation and reaching equilibrium at 90 min of incubation. The kinetic analysis shows an apparent pseudo first order association rate constant (Kob) equivalent to 4 x 10(-2) min-1. Following equilibrium with the tracer, a large excess of unlabelled inhibin (1.27 microM) was able to displace 84 percent of the specific binding within 120 min of incubation and 50 percent of the binding at approximately 40 min. The analysis under displacing conditions showed an apparent dissociation rate constant (K2) equals to 1.5 x 10(-2) min-1 and an apparent association rate constant (K1) equals to 1.3 x 10(9) M min-1. Thus, the estimation of the apparent kinetic equilibrium dissociation constant (Kd = K2/K2) of the binding of inhibin to bovine pituitary membranes was 1.2 nM. These results show for the first time the existence of bovine inhibin specific binding sites in bovine pituitary, and also that such a binding can take place in the absence of either gonadal and/or hypothalamic influences. They also contribute to the better understanding of the role of non-steroidal hormones such as inhibin, in the regulation of gonadotrophin secretion

Alojamiento conjunto: relacion intrahospitalaria madre-hijo en el puerperio. / Rooming-in care; intrahospilar mother-child relations in puerpurium

Se destaca la importancia de los beneficios que recibe el recien nacido por permanecer en intimo contacto fisico y emocional con su madre desde minutos despues de su nacimiento, hasta su alta hospitalaria. Aunque esta practica no representa ninguna innovacion, ha cobrado importancia en la medicina perinatal moderna, por loque pretendiendo avalar tales beneficios, se realizo el presente estudio en el que se incluyeron 200 recien nacidos sanos cuyo nacimiento tuvo lugar en el area tocoquirurgica de nuestro hospital; 100 de ellos fueron asistidos en el cunero normal hasta su alta y los otros 100, en cunas al lado de sus madres, a las que se proporciono orientacion audiovisual sobre cuidados generales del recien nacido, principios higienicos y tecnica de amamantamiento. Los resultados muestran que se favorecio significativamente la lactancia al pecho materno; tambien mejoro el cuidado del neonato por sus madres, eliminando algunos tabues y costumbres negativas para la salud del nino. El programa fue entusiastamente aceptado por las madres y agilizo el trabajo de la enfermera en esta area.No se pudo comprobar disminucion de las infecciones intercurrentes o domiciliares posthospitalizacion del periodo neonatal en este estudio
