    Full Text Available The objective of this study was to evaluate the accumulation of matter, dry matter content of Brix and two varieties of sugar cane, influenced by the phosphorus cultivated on "Zona da Mata" region, State of Alagoas. The experiment, a factorial 2 x 6, was composed of two varieties of cane; RB867515 and RB92579 and six phosphorus levels: zero, 30, 60, 90, 120 and 150 kg ha-1, with the source of the phosphorus triple superphosphate . Was also used nitrogen and potassium in doses equivalent to 100 and 200 kg ha-1 and K, respectively. The soil of the experimental area was set to raise the base saturation to 60%. At the beginning of the first rainfall of the rainy season of 2006 was performed with micro fertilization in coverage, in doses equivalent to 6,0; 6,0 and 7,0 kg ha-1 of Cu, Zn and Mn, respectively. Was The chemical control of weeds. Every month, from August to October 2006, samples were collected in the cane plant. There was initially the number of plants m2, followed by weighing the material. It was subsequently withdrawn a subsample containing ten plants for weighing. After weighing the material was passed in horsemanship and homogenized, again drew up a sample of approximately 300g, leading them to forced ventilation oven at 65 ºC, to obtain constant weight. Resulting in the production of natural (MN and dry matter (DM. In July, we analyzed the levels of Brix% juice in the refractometer Brix. The average values of production of natural (MN, dry matter (DM and contents of Brix% were subjected to analysis of variance and regression for variables. The accumulation of dry matter and were influenced by fertilization. The contents of Brix% in two varieties did not suffer significant influence of fertilization.

    Twenty patients treated by surgery for Perthes` disease were studied between 4 and 9 years postoperatively. In the clinical investigation eight patients complained of persistent stress-induced pain. In nine patients flexion, extension, ab- and adduction of the hip joint was limited. In the MRI-Study of ten hip joints a reduction of fatty marrow was seen in the femoral head. In 11 hip joints of patients complaining of persistent pain, a deformation of the femoral head (n = 2), a dysplasia of the femoral metaphysis (n = 2), and diaphysis (n = 4) or both (n = 2) were seen. In another five patients an additional dysplasia of the acetabulum was visualized. All these findings were diagnosed by X-ray studies as well. However, only by MRI were the extents of the postoperative defects of femoral spongiosa diagnosed in fifteen hip joints. (orig.) [Deutsch] 20 wegen eines Morbus Perthes operierte Patienten wurden 4-9 Jahre nach einer Umstellungsosteotomie klinisch, radiologisch und kernspintomographisch untersucht. Bei der klinischen Nachuntersuchung gaben 8 Patienten persistierende Beschwerden bei Belastung an. Bei der koerperlichen Untersuchung war die Flexion und Extension bei 9 sowie die Abduktion und Adduktion bei einem Patienten eingeschraenkt. Bei der kernspintomographischen Untersuchung liessen sich bei 10 Hueftgelenken Residuen des M. Perthes im Fettmark des Femurkopfs nachweisen. An 11 Hueftkoepfen wurden pathologische Veraenderungen wie eine Femurkopfentrundung (n = 2), eine Deformierung der Femurmeta- (n = 3) und -diaphyse (n = 4) bis hin zur hirtenstabfoermigen Konfiguration (n = 2) nachgewiesen. Bei 5 Patienten wurde eine Pfannendysplasie gefunden. Diese Befunde waren auch roentgenologisch darzustellen. Als postoperative Defekte waren im Schaftmark des Femurs eine langstreckige Hoehlenbildung mit Zysten oder durch Fettmark aufgefuellte Spongiosadefekte bei 15 Hueftgelenken nur kernspintomographisch nachweisbar.

    Full Text Available O estudo teve por objetivo obter frações de farinha de aveia enriquecidas em amido e em fibras pelo fracionamento a seco e modificar quimicamente (fosfatação o amido da fração rica neste constituinte, avaliando suas propriedades funcionais. O fracionamento foi efetuado utilizando-se as granulometrias > 300, 212-300, 150-212, e 300 µm e 212-300 µm foram semelhantes, com aumento de aproximadamente 1,5 e 2,7 vezes nos teores de proteína e fibra, e redução de 0,5-0,6 vezes no teor de amido, quando comparadas à farinha integral. As frações 212-150 µm e The objective of this study was to obtain starch and fiber enriched oatmeal fractions through sieving, chemically modifying (phosphorylation the starch enriched fraction, and evaluating its functional properties. Fractionation was performed using > 300, 212-300, 150-212, and 300 µm and 212-300 µm were similar and had increased protein and fiber content (1.5 and 2.7 fold, but reduced starch content (0.5-0.6 fold when compared to whole oatmeal. Fractions 212-150 µm and < 150 µm were similar and had the highest starch content (around 70%. The starch-rich fraction < 150 µm that had the highest yield during sieving (35.5% was phosphorylated with sodium tripolyphosphate at 150-155 °C for 20 and 40 min, yielding 0.39 and 0.32% phosphorus bound, respectively. Cold water binding capacity increased (1.9-3.3 fold, while syneresis at 5 °C or after freezing/thawing was significantly reduced (6-20 and 5-6 fold, respectively in phosphorylated starch fraction when compared to the native starch fraction. Phosphorylation reduced the increase of pasta opacity during storage at 5 °C, which indicates a lower retrogradation tendency. Thus, oatmeal sieving yielded fractions either enriched in fiber and protein or enriched in starch. Moreover, phosphorylation of the starch-rich fraction improved their functional properties, which may increase the potential applicability and economic value of this
