    Notes: Summary The ultrastructural features of five biopsies of gliomatosis cerebri (GC) are described. Four main types of tumour cells are seen: anaplastic astrocytes poor in organelles with a variable amount of glial microfilaments; atypical oligodendrocytes with scanty cytoplasm in which microtubules are present; intermediate forms with aboundant cytoplasm rich in organelles, with microtubules and microfilaments; and small cells with round nuclei and a very scanty rim of cytoplasm. In two cases several concentrically folded cytoplasmic lamellae of glial processes were arranged either around themselves or around the perikaryon of other cells. This ultrasructural study indicates that GC is a neoplastic process of small undifferentiated elements, transitional forms of astroglia (to oligodendroglia) and anaplastic cells of astrocytic origin in all stages of development.

    Notes: Abstract Diffuse-reflectance Fourier transform-infrared spectroscopic (DRIFT) microanalysis (10 μg samples) of a selected series of flavonoids was studied, comparing to transmission FT-IR spectroscopic analysis of the same samples at the mg level. DRIFT was shown to be a useful, sample-saving and reliable IR technique for the structural analysis and compound identification of the mainSilybum genus 3-OH-flavonolignans (silybin, isosilybin, silydianin, silychristin and isosilychristin) and the dihydroflavonol taxifolin.

    Notes: Summary For a histochemical study of ubiquinones in newborn and adult mice, the hydroquinone-tetrazolium-reductase reaction was performed in cryostat serial sections of the central cerebellar nuclei. This enzyme was studied in various structures at different stages of postnatal development. The present study shows that in the central nuclei the ubiquinones display less activity during development than in the adult mouse. The histochemical maturation is slow as compared with Purkinje cells, the rest of the molecular layer, the motor nuclei of the brain stem and the anterior horns of the medulla. The relationship of these histochemical findings and the metabolic significance of changes in the patterns of ubiquinones is discussed.

    Notes: Abstract Melorheostosis is a benign, rare, congenital disorder of hyperostosis of one or more bones. In this report, we describe a 5-year-old girl with melorheostosis of the left iliac wing, femur, and tibia who developed severe hypertension secondary to left renal artery stenosis. Numerous soft tissue and vascular anomalies have been reported in patients with melorheostosis. To our knowledge this is the first case where renal artery stenosis has been associated with melorheostosis. Several hypotheses for bone and vascular involvement in melorheostosis are reviewed.

    Notes: 3-Hydroxy-3-methylglutaryl-CoA reductase (EC 1.1.1.34), the major rate-limiting enzyme of cholesterogenesis, was studied in epithelial cells isolated in a villus to crypt gradient from chick duodenum, jejunum and ileum, in order to resolve the apparent controversy that exists on the anatomical localization of sterol synthesis in the intestine. Consistent separation was demonstrated by using the marker enzymes alkaline phosphatase, specific to the villus cells, and thymidine kinase, specific to the crypt cells. No relative difference in stability was observed, as shown by the equal distribution of acid phosphatase. Cells were 90-95 per cent viable. The highest specific activity of reductase was located in the microsomal fraction (41 per cent of the total). The mitochondria had lower specific activity (8 per cent of the total). The distribution of reductase activity in epithelial cells of the villus-crypt axis was also studied. The specific activity in each cell fraction from chick duodenum was clearly lower than that in jejunum and ileum. The jejunal and ileal crypt regions showed lower specific activity than the villus cells. About 70 per cent of total reductase activity was found in cells from the upper and the mid villus fraction in each intestinal segment.

    Description: Se evaluaron diferentes densidades poblacionales en el engorde de camarón blanco (Litopenaeus vannamei) con tecnología biofloc (TBF) y pienso de baja proteína bruta (22 %). Un total de 750 juveniles de 0,71 ± 0,01 g de peso medio inicial se distribuyeron según diseño completamente aleatorizado en cuatro tratamientos con tres repeticiones. Los tratamientos fueron densidades de 50; 100; 150 y 200 animales/m2. No se encontraron diferencias en los nutrientes residuales para los tratamientos experimentales. El peso final (p = 0,02) y la supervivencia (p = 0,001) se redujeron con la más alta densidad (200 animales/m2). En tanto, la conversión alimentaria y la eficiencia proteica no difirieron entre los tratamientos. El rendimiento incrementó al aumentar las densidades (0,261; 0,469; 0,615; 0,606 kg/m2). Bajo las condiciones de cultivo de este estudio, se exhibieron los mejores indicadores productivos a una densidad de 150 animales/m2. Los resultados alcanzados permiten concluir que es factible el incremento de la densidad poblacional en el engorde de camarón blanco (L. vannamei) en tecnología biofloc con baja proteína dietética.
    Description: Different population densities were evaluated in white shrimp (Litopenaeus vannamei) fattening with biofloc (TBF) technology and low crude protein feed (22 %). A total of 750 juveniles of 0,71 ± 0,01 g of initial mean weight were distributed according to a completely randomized design in four treatments with three repetitions. The treatments were densities of 50; 100; 150 and 200 animals/m2. No differences in residual nutrients were found for the experimental treatments. Final weight (p = 0,02) and survival (p = 0,001) were reduced with the highest density (200 animals/m2). Meanwhile, feed conversion and protein efficiency differed between treatments. Yield increased with increasing densities (0,261; 0,469; 0,615; 0,606 kg/m2). Under the culture conditions of this study, the best productive indicators were exhibited at a density of 150 animals/m2. The results obtained allow us to conclude that it is feasible to increase the population density in the fattening of white shrimp (L. vannamei) in biofloc technology with low dietary protein.

    Description: Un total de 270 alevines (10,7 ± 0,06 g de peso promedio) se distribuyeron al azar en tres tratamientos con tres repeticiones, según diseño completamente aleatorizado, para evaluar el remplazo de alto porcentaje de harina de pescado (HP) por ensilados de subproductos pesqueros (EP) en dietas extrusadas para Clarias gariepinus. Los tratamientos fueron el pienso para alevinaje de bagres con 25 % de HP (control) y dos dietas alternativas con 10 % (base seca) de EP; uno preparado con ácido sulfúrico al 98 % y el otro con ácido fórmico. Los animales se alimentaron durante 60 días. No se encontraron diferencias en los pesos finales (66,63 g; 66,27 g y 70,71 g) y conversión alimentaria (1,18; 1,18 y 1,15). Sin embargo, se encontraron diferencias (p = 0,001) para la eficiencia proteica entre la dieta con HP (2,34) y los EP (3,09 y 3,18). Las supervivencias fueron excelentes en todos los tratamientos (〉 96,66 %). El análisis económico mostró que las utilidades con los ensilados (US $ 2 534,22/t y US $ 2 430,05/t) fueron superiores al control (US $ 1 689,44/t). Se concluye que los ensilados químicos de subproductos pesqueros pueden remplazar elevado porcentaje de HP en dietas extrusadas para alevines de Clarias gariepinus, con un efecto económico positivo, al disminuir la importación de harina de pescado.
    Description: A total of 270 fingerlings (10,7 ± 0,06 g average weight) were randomly distributed in three treatments with three repetitions, according to a completely randomized design, to evaluate the replacement of high percentage of fishmeal (HP) by fishery by-product silage (FS) in extruded diets for Clarias gariepinus. The treatments were the feed for catfish fingerlings with 25 % HP (control) and two alternative diets with 10 % (dry basis) EP; one prepared with 98 % sulfuric acid and the other with formic acid. The animals were fed for 60 days. No differences were found in final weights (66,63; 66,27 and 70,71 g) and feed conversion (1,18; 1,18 and 1,15). However, differences (p = 0,001) were found for protein efficiency between the HP diet (2,34) and the EP diets (3,09 and 3,18). Survivals were excellent in all treatments (〉 96,66 %). The economic analysis showed that the profits with the silages (US$ 2 534,22 and 2 430,05/t) were higher than the control (US$ 1 689,44/t). It is concluded that chemical silage from fishery by-products can replace a high percentage of HP in extruded diets for Clarias gariepinus fingerlings, with a positive economic effect, by reducing the import of fishmeal.
