ABSTRACT
Este estudo avaliou a capacidade de um sal mineral rico em molibdênio (Mo) em prevenir a intoxicação cúprica acumulativa (ICA), mediante a análise das variáveis clínicas e dos teores de cobre (Cu) e Mo hepático. Foram utilizados 25 ovinos cruzados da raça Ile-de-France, aleatoriamente distribuídos igualmente em cinco grupos, em que o grupo 1 recebia dieta contendo 80% de volumoso e 20% de concentrado, os grupos 2 e 3 recebiam 50% de volumoso e 50% de concentrado, e os grupos 4 e 5 recebiam a mesma dieta dos grupos 2 e 3, com a adição diária de 150mg de sulfato de Cu. Os grupos 1, 3 e 5 recebiam sal mineral contendo 300ppm de Mo. Foram realizadas três biópsias hepáticas para determinação de Cu, Mo e Zn. Três ovinos do grupo 4 e um do grupo 5 manifestaram ICA. Não houve diferença na frequência de mortalidade entre os grupos (P=0,56). Os teores de Cu hepático nos ovinos com ICA (2450ppm) foram superiores aos que não intoxicaram (1518ppm). Quanto maior a ingestão de Mo na dieta, menor foi o acúmulo de Cu hepático ao término do experimento (r = -0,72).(AU)
The aim of this project is to evaluate the capacity of a molybdenum-rich mineral salt in the prevention of cumulative cooper poisoning (CCP) in sheep, through clinical and hepatic copper and molybdenum concentrations. Twenty five crossbreed Ile-de-France sheep were randomly distributed equally into five groups. Group 1 received a 80% forage and 20% concentrate diet, groups 2 and 3 received a 50% forage and 50% concentrate diet, and groups 4 and 5 received the same diet as groups 2 and 3 with a daily supplementation of 150 mg of copper sulfate. Groups 1, 3 and 5 received a mineral salt with 300 ppm of molybdenum. Three times during the experiment a liver biopsy was carried out to evaluate the degree of copper accumulation. Three sheep from group 4 and one sheep from group 5 showed a clinical picture of CCP. There was no difference in the frequency of mortality between groups 4 and 5 (P=0.56). The liver copper concentration was higher in sheep with CCP (2450 ppm) compared to sheep that did not present CCP (1518 ppm). The higher the ingestion of molybdenum in the diet the lower the liver copper concentration at the end of the experiment (r=-0.72).(AU)

La anatomía de la mano presenta padrones generales en la distribución de los nervios responsables de la inervación motora y sensitiva. Sin embargo, se encuentran variaciones que son de interés para la anatomía quirúrgica de la región. En una serie de 20 manos disecadas, en 19 (95 por ciento) observamos que el nervio digital palmar propio del lado ulnar del dedo mínimo correspondía a un ramo directo del nervio ulnar y en el caso restante (5 por ciento), de un cadáver de sexo femenino, se observó un ramo de origen antebraquial que participó en la formación del nervio digital palmar propio ulnar del dedo mínimo. Este ramo se originó desde el tronco del nervio ulnar, distal al origen del ramo dorsal de este nervio y proximal al hueso pisiforme. En su trayecto pasó a través del músculo abductor del dedo mínimo, emergiendo por la cara superficial de éste a una distancia de 11,3 mm del origen del músculo en el hueso pisiforme, uniéndose al nervio digital palmar propio del dedo mínimo, distal al hueso mencionado. A pesar que la literatura muestra diversas variaciones en la formación y distribución de los nervios en la mano, la disposición descrita es inusual y no ha sido mencionada en ella.
The hand anatomy presents general patterns in motor and sensitive nerves distribution. However, is possible to find some variations that are very important for the surgical anatomy of the region. We study 20 hands of 10 cadaver individuals, fixed in 10 percent formaldehyde solution. We found in 19 hands (95 percent) that the ulnar proper palmar digital nerve of the little finger was a direct branch of the ulnar nerve and only one case (5 percent) - of female cadaver ¡ we observed one branch originated from the forearm, which was a part in the formation of the nerve mentioned above. This branch originated from the trunk of the ulnar nerve, distal to the origin of the dorsal branch of this nerve, proximal to the pisiform bone. This nerve passed through of the abductor digiti minimi muscle and then it emerged by the superficial face of this muscle, 11,3 mm distal to its origin in the pisiform bone. Then, it joined to the ulnar proper palmar digital nerve of the little finger, distal to mentioned bone. Although the literature describes innumerous variations in the formation and distribution of the hand nerves, this disposition is rare and has not been mentioned.

El diagnóstico serológico es de gran importancia para la detección de la infección con el virus de la diarrea viral bovina (BVDV), importante patógeno asociado a fallas reproductivas entre otras. Las técnicas más utilizadas para la detección de anticuerpos contra BVDV son la seroneutralización en cultivos celulares (SN) y el ELISA. El objetivo del presente trabajo fue estandarizar un ELISA de esquema indirecto comparando sus resultados con la SN. Con resultados de sensibilidad de diagnóstico mayores o iguales que 98,31 por ciento y de especificidad de diagnóstico igual a 100 por ciento, el ELISA-BVDV resultó ser un método sensible, específico y repetible. Además es una técnica de realización rápida, sencilla, económica y de fácil transferencia.

São observadas as características microscópicas das folhas de Bauhinia blakeana Dunn., espécie conhecida no Brasil como "Pata de vaca" e usada pela população como hipoglicemiante. As análises dos cortes transversais e das dissociações epidérmicas indicam a presença de um mesofilo dorsiventral contendo espaços intercelulares, protegido por epidermes com tricomas de diversos aspectos e estômatos paracíticos e anomocíticos. O pecíolo, plano-convexo, pubescente, apresenta duas saliências, colênquima angular e feixes vasculares colaterais e bicolaterais.
The paper describes the microscopic characteristics of the leaves of Bauhinia blakeana Dunn., known in Brazil as "pata de vaca" and used as a hypoglycemic remedy. Transverse sections and epidermal dissociations indicate the presence of a dorsiventral mesophyll protected by epidermis with trichomes of diverse types and paracytic and anomocytic stomata. The petiole, which is plane-convex, pubescent, shows two excrescences, an angular collenchyma and collateral and bicollateral vascular bundles.
ABSTRACT
To establish if BTV was circulating in Argentina, 94 bovines from the Santo TomÚ and Ituzaingó Departments of Corrientes Province were sampled every 30-60 days during 14 months. Red blood cells from those animals that showed seroconvertion with a c-ELISA were processed for virus isolation by inoculation in embryonated chicken eggs and cell cultures. Cells with CPE were positive by direct and indirect immunofluorescence with BTV specific reagents. These samples examined by electron microscopy showed virus particles with BTV morphological characteristics. Blood samples and tissue culture supernantants were positive by RT-PCR technique with primers corresponding to the segment 3 of the BTV genome. Haematophagous insects were captured in one farm using light traps and Culicoides insignis Lutz was the predominant species detected. This is the first isolation of BTV in Argentina from northeastern bovines without any disease symptom.

Objetivo: Establecer la prevalencia de la infección por chlamydia trachomatis en una población con problemas de la reproducción. Diseño: estudio descriptivo epidemiológico realizado entre julio de 1997 y junio de 1998. Material: A 140 parejas con problemas de reproducción, atendidas en la Unidad de Reproducción Humana del Hospital Nacional Edgardo Rebagliati Martins de EsSalud, se les tomó muestra endocervical (mujeres) o uretral (hombres) para detección de clamidia. Medidas de estudios: Detección de presencia de chlamydia trachomatis por método de inmunofluorescencia directa, IgG e IgA. Resultados: Al estudio de antígeno de clamidia por inmunofluorescencia directa, 122 (43,6 por ciento) pacientes fueron positivos, en 59,8 por ciento en ambos miembros de la pareja. La mayoría de los pacientes no presentó síntomas, en 23 por ciento no hubo alteración del espermatograma, a pesar de ser positivo a clamidia y, en las mujeres, la mayoría mostró alteraciones tubáricas a la laparoscopia y un 12 por ciento microvesículas en la serosa. Conclusión: La prevalencia de infección por clamidia en parejas con infertilidad en nuestro medio es alta, lo que debe ser considerado en los protocolos de manejo en reproducción, para diagnóstico y tratamiento, así como para tomar medidas adecuadas de prevención.

This study was designed to compare two methods of breast milk expression, namely, the manual and the pumping method using a hand-held cylindric pump. The parameters evaluated were (i) the output of breast milk during milk expression sessions of 15 minutes' duration, and, (ii) the subjective preference of the method by the mothers. In the first phase, 22 mothers whose infants were on gavage feeding in the nursery, had 3 sittings each by the two methods on 4th and 5th postnatal days (66 expression). It was seen that the use of breast pump (Medela) was associated with significantly higher volume of breast milk expressed per session (41.57 +/- 16.05 ml vs. 21.7 +/- 10.5 ml, P < 0.001). In the second phase, 14 mothers had such sessions (42 each) not only on the 4th and 5th postnatal days, but lso on days 8 and 9. It was again seen that, the volume of breast milk expressed was greater by the pump method than the manual expression (on day 5 and 6 (46.8 +/- 26.3 ml vs 31.2 +/- 15.5 ml, P < 0.01) as well as on day 8 and 9 (50.40 +/- 11.2 ml vs 38.49 +/- 13.4 ml, P < 0.01). Subjectively, the pump expression was preferred by the mothers on day 4 & 5, while the manual expression was the preference on days 8 & 9. The use of breast pump is more efficient than the manual system of expression of breast milk among mothers whose infants are not directly breast-fed. It is recommended that in case the mothers prefer to use the manual method, let them express as much milk as possible by this method initially, and then follow it up with a short period of pumping to ensure complete evacuation of breasts.

El absceso esplénico es una afección rara que debe ser sospechada ante un cuadro clínico de fiebre, dolor abdominal en el cuadrante superior izquierdo, irradiado a hombro ipsilateral, tumoración palpable en hipocondrio izquierdo, manifestaciones de sepsis y antecedentes de hemoglobinopatías, enfermedades subyacentes como diabetes mellitus, endocarditis bacteriana, estados de inmunosupresión (SIDA, alcohólicos, leucemia, pacientes con quimioterapia), y drogadictos. El diagnóstico se establece por T.A.C. ecografía abdominal, centellografía esplénica, arteriografía, radiografía simple de tórax y abdomen. El tratamiento esencial es la esplenectomia que puede ser total o parcial de acuerdo a la individualización de cada caso, y a la experiencia y habilidad del cirujano. Debe tomarse siempre muestra para cultivo a fin de aislar el germen causal para instalar tratamiento específico. Nuestro caso sesemeja a los descritos en la literatura mundial y se confirma por anatomía patológica, presentando en el mismo la demora ya descrita y sin contar con los recursos suficientes para su diagnóstico definitivo

A mediados de octubre de 1981 se presento un brote de conjuntivitis hemorragica en nuestro cunero. En 72 horas se diagnosticaron 16 recien nacidos con el padecimiento. El promedio del periodo de incubacion fue de 25 horas. Se realizaron pruebas de laboratorio en ninos sanos y enfermos, encontrandose bacterias no patogenas similares en ambos. Mediante la prueba estadistica de "t" de Student del periodo de incubacion, se infirio que el agente causal probablemente era el mismo que produjo la epidemia de conjuntivitis hemorragica aguda que afectaba en esos dias a la comunidad
