Abstract: many studies have showed that some individuals failing in demonstrating their mental conflicts may express them bodily, through psychosomatic symptoms. it has also been investigated how situations of stress, anxiety and depression contribute to the formation process and evolution of some diseases, including inflammatory bowel disease. this research gathered thirty patients with ulcerative retocolitis and crohn's disease, who were submitted to three psychological tests: the beck anxiety inventory, the beck depression inventory, and the lipp stress symptom inventory. afterwards, nine of them were chosen to perform a brief psychotherapy work group. the tests revealed that the emotional condition although not the main responsible, may aggravate the pathology by affecting one's body and mental defenses. the psychotherapy work displayed emotional conditions until recently unnoticed; though present in life, symptomatically manifested by somatizations.

Abstract: the chungará lake (18o14' s, 69o09' w), the most austral and highest among the intertropical andean lakes, is located at 4,520 m of altitude. it is a polymictic system of tectonic-volcanic origin with a maximum depth of 34 m. it has a narrow temperature range in depth and seasonally (4-11 oc), and which mean annual values show an increment in 1.2 oc between 1986-1987 and 1998-1999 periods. the system total volume has reduced significatively (-6.58 %) during both periods of study and consequently in the maximum depth. salinity has increased significatively, presenting maximum values of 1,464 μmhos and 2,650 μmhos, respectively. these changes would be modifying the phytoplankton composition and abundance and are also probably associated to the significative chlorophyll a decrease between these two periods (p < 0.0054).

Abstract: stromal cells are the most abundant cell population present in decidual tissue; they are involved in key processes during embryo implantation, fetal nutrition and the pregnancy maintenance. described procedures for stromal cells isolation require the use of many monoclonal antibodies due to contamination with another cell types in the decidua; besides, some markers of stromal cells show variability during the days of gestation. in this study, we standardized a procedure for isolation by enzymatic digestion, density gradient and adherence to plastic. murine stromal cells were characterized by exclusion of markers that are expressed in macrophages (f4-80), epithelial cells and trophoblast (cytokeratin-7), yielding a 98% of negative cells for these markers that correspond to stromal cells. this isolation procedure permits to obtain stromal cells with less expensive and high efficiency methods that provide a useful cellular model to study the physiology of gestation in different species.

Abstract: RESUMEN El lago Chungará, es el más austral y de mayor altura de los lagos altoandinos, está ubicado a 4.520 m de altitud en el altiplano chileno (18o14' S, 69o09' O); es un lago polimíctico-frío, con origen tectónico- volcánico y 34 m de profundidad máxima. Presenta variaciones reducidas de temperatura entre profundidades y estaciones del a o (4 a 11 oC), el promedio de temperatura anual se ha incrementado en 1,2 oC entre los períodos 1986-1987 y 1998-1999. Entre los mismos períodos se observó una disminución significativa en el volumen del lago (_6,58 %) y consecuentemente en la profundidad máxima. Conjuntamente la salinidad aumentó significativamente con valores máximos de 1.464 μmhos y 2.650 μmhos para cada período. Estos cambios pueden ser las causas de la modificación en composición y abundancia del fitoplancton, asociadas, además, a la disminución significativa de la clorofila a (P < 0,0054). The Chungará lake (18o14' S, 69o09' W), the most austral and highest among the intertropical andean lakes, is located at 4,520 m of altitude.

It has a narrow temperature range in depth and seasonally (4-11 oC), and which mean annual values show an increment in 1.2 oC between 1986-1987 and 1998-1999 periods.

Abstract: Las células estromales son las células más abundantes presentes en la decidua y juegan un papel muy importante durante la implantación, la nutrición fetal y el mantenimiento del embarazo. Los procedimientos que se han descrito para el aislamiento de células estromales requieren el uso de muchos anticuerpos monoclonales ya que hay contaminación con otros tipos celulares en la decidua y además algunos marcadores características de células estromales, muestran variabilidad en los diferentes días de la gestación. En este estudio se estandarizó un procedimiento de aislamiento por digestión enzimática, gradiente de densidad y adherencia al plástico y se caracterizaron las células estromales murinas por exclusión de marcadores que se expresan en macrófagos (F4-80), células epiteliales y trofoblasto (citoqueratina-7), obteniéndose un 98% de células negativas para estos marcadores que correspondería a las células estromales. Esta técnica de aislamiento permite obtener células estromales con métodos menos costosos y altamente eficientes que facilita el acceso a un modelo celular de gran utilidad en el estudio de la fisiología de la gestación en diferentes especies.

Abstract: the leafhopper of corn, dalbulus maidis (delong & wolcott, 1923) (hemiptera: cicadelidae), is considered one of the main corn pest due to its damage of sap suction and disease transmission to plants. this work had the aim to get information about population fluctuation of d. maidis in the southern region of mato grosso do sul state. yellow stick cards of double side (7 by 12cm) were installed fortnightly on a wood frame of 0.5m and 1.5 above soil surface within areas cultivated with corn in dourados and ponta por?, ms and stayed in the area for seven days. the same kind of traps was also installed in a grass-plot of dourados, ms without corn crop nearby. two peaks of leafhopper were observed being one during the dry period (the period without corn in the field - between july and september) and the other during summer (between december and january). stick traps installed at 0.5m above soil surface did capture significantly more leafhopper than the ones installed at 1.5m if we consider all sampling carried out during the two years of study.
Influência do substrato sobre a reprodu??o de Subulina octona (Brugüière) (Mollusca, Subulinidae), sob condi??es de laboratório

Abstract: the influence of substrate on reproduction of subulina octona (brugüière, 1789), reared in sand, clay and humus, was investigated under laboratorial conditions. there were significant differences in onset of sexual maturity, egg production, shell length and aging in each reproductive event, total number of eggs produced and total number of reproductive events. the individuals reared in humus spent more time to reach sexual maturity, as well as to accomplish the subsequent reproductive events. moreover, produced fewer eggs in the second, third and fourth ovipositions and exhibited a longer interval between the first and second reproductive events. after 120 days of experiment such individuals had produced fewer eggs, and performed fewer reproductive events, when compared with those kept in sand and clay. there was a progressive decline in egg number increase with time. in this study was also observed that s. octona of different developmental stages fed on substrate and the molluscs reared in humus consumed less food. this is probably due to the fact that humus is more likely to be take as food resource. so that, the snails reared in humus tend to consume more substrate and less ration, obtaining less proteins, carbohydrates and calcium than those snails reared in sand and clay. this low intake of ration might have negative effects over reproduction of the snails.
