Leukemoid Reaction: Presentation of Two Cases

The leukemoid reaction is defined by the presence in peripheral blood of white cells above 50,000/mm3 or neutrophils above 30,000/mm3 . The frequency varies between 1.3 and 15% of newborns admitted to neonatal intensive care units [1]. It usually appears during the first two weeks of life and more frequently during the first four days, the duration is about 8.5 days [2]. In extremely premature, this process is produced by an inflammatory response that active cytokines who increased granulocyte colony-stimulating factors (G-CSF). These induce the production of neutrophils that cause hyperleukocytosis

Interacção entre salinidade e fertilização azotada em sorgo sacarino (Sorghum bicolor L. Moench)

Plantas de sorgo sacarino foram expostas a quatro níveis de condutividade eléctrica (0, 2, 4, 6 dS m-1) e três níveis de fertilização azotada (20%, 60% e 100%) na água de rega, num desenho experimental 4 × 3, com 6 repetições, num total de 78 vasos. Pretendeu-se, assim, avaliar o efeito da interacção entre os vários níveis de salinidade e de fertilização azotado na tolerância das plantas de sorgo à salinidade, pela avaliação de parâmetros fisiológicos e do crescimento das plantas. As plantas sujeitas a altas concentrações de sal (acima de 4 dS m-1) apresentaram decréscimos muito pronunciados nos parâmetros evapotranspiração (ET), condutância estomática (gs), teor relativo em clorofilas e taxa de fotossíntese líquida (A), o que se reflectiu numa redução da sua biomassa final. Para níveis de salinidade na água de rega baixos (da ordem de 2 dS m-1), os compostos azotados parecem beneficiar a tolerância ao sal. No entanto, nas plantas expostas a elevadas concentrações de sal (maior que 4 dS m-1), o aumento da fertilização azotada levou a decréscimos no crescimento, possivelmente porque o azoto se passou a comportar como um sal, potenciando o efeito salino

Creation and design of a guidelined model for the management of public urban spaces and services

The objective of this project is the creation of a guidelined management model to optimize public spaces and urban services. The indicators composing the computerized Balanced Scorecard of the model provide information of the subsystems that make up the spaces and its utilities in four strategic blocks that allow their expansion. The model is founded on the basis of systematically collecting data and then processing the data to create quality indexes from the analyzed sections, depending on the level of degradation of its subsystems, as well as the estimated repair costs. This information makes it possible to prioritize the type of intervention to be made by the manager. The purpose of this model is to be used, in the future, to estimate the durability of the different elements that compose the roads and to manage them in a more sustainable way. The model was tested on the urban sprawl of Mataró (Barcelona), which consists of a total of 141,5 km of roads and 331 crossroads, analyzed with its public furnishings and fixturesPostprint (published version

Humoral immune response of pregnant goats to two Corynebacterium pseudotuberculosis bacterin formulations

Caseous lymphadenitis is a chronic suppurative bacterial disease caused by Corynebacterium pseudotuberculosis with a high prevalence in small ruminants. Different vaccine preparations have been employed to control this disease. The adjuvant used in the formulation is a critical factor for the improvement of vaccine efficacy. No commercial vaccines are available in Argentina. The aims of the present work were to compare the specific antibody response against a C. pseudotuberculosis whole cell vaccine formulated with a classical and an immunoestimulant adjuvant in pregnant goats, and to assess the transfer of vaccine- specific antibodies from the goat to the offspring through colostrum. Twenty three pregnant goats were vaccinated. The animals were randomly allocated to three groups: control, aluminum hydroxide Al(OH)3 adjuvant and a new cage-like particle adjuvant (ISPA). Antibodies (IgG) against this antigen were measured by ELISA. A robust humoral immune response was detected in vaccinated animals, with production of specific IgG, without finding significant differences between the vaccines formulated with different adjuvants. High levels of specific antibodies were detected in colostrum samples from both immunized groups, which were passively transfered from goats to offprings. No adverse local reactions in the vaccines injection sites were detected.Fil: Auad, Jordana. Universidad Católica de Córdoba; ArgentinaFil: Cerutti, Julieta.

Effect of inhibitors on chloride-dependent transmural potential in the rectal wall of Schistocerca gregaria

Previous experiments in vitro revealed a transmural potential difference (PD) and a shortcircuit current (IX) across the rectal wall of Schistocerca yregariu. which were dependent on chloride ions in lumen. The present report shows that anoxia. dinitrophenol and cyanide inhibit DP and IX. proving that the required energy derives from oxidative metabolism. Acetazolamide also inhibits DP and Isc. Ouabain. when in haemocoele, has also an inhibitory effect, not ascribable to a Na’-K’ pump blocking action. It is suggested that HCO; plays an important rBle in the active transport of Cl- from lumen to haemocoele and that ouabain may in some way inhibit chloride pumping

Chloride-dependent transmural potential in the rectal wall of schistocerca gregaria

Rectum trammural potential (PD) and short-circuit current (Isc) of the desert locust, Schistocercu gregaria, have been studied in vitro, with everted rectal wall preparations in solutions of different ionic composition. Initially, a PD of about 35 mV (lumen positive) and a Isc of about 300 4 cm-* were recorded. Omission of sodium or potassium (Tris as substitute), from the luminal side or from both sides led to an increase of 4 to 6 mV in PD (lumen more positive) together with an increase in IBC. In the absence of chloride alone (sulphate as substitute) the PD quickly dropped to nearly zero. In each case the control values were recovered on replacing the corresponding ions. Neither the PD nor the IW changed when substitutions affected only the haemocoelic solution. These findings corroborate the assumption that active transport of chloride ions from lumen to haemolymph is the major factor for transmural PD and account for the short-circuit current in the rectal wall of desert locust. A working scheme is given to explain the influence of sodium, potassium, and chloride ions on the PD
