Grape (Vitis Vinifera) Pomace Flour as Pigment Agent of Quail Eggs

ABSTRACT The aim of the study was to evaluate the effect of dietary grape pomace flour (GPF) inclusion on the performance and egg quality of European quails (Coturnix coturnix coturnix) in lay. One hundred ninety-two (192), 42-day-old quails were distributed in a completely randomized design with four treatments (0, 2, 4 and 6% grape pomace flour inclusion) with six replicates of eight birds each. The performance parameters egg weight (g), average feed intake (g/bird), total feed intake (g/bird), egg production (%) and feed conversion ratio (kg/dozen) were evaluated, as well as egg quality traits Haugh unit, albumen weight (g), yolk weight (g), eggshell thickness (mm), egg specific gravity (g/cm3), and yolk pigmentation. There was no effect (p>0.05) of dietary GPF levels on egg production, feed intake, or feed conversion ratio. Egg weight, albumen weight, and egg specific gravity linearly decreased (p0.05) by the treatments. A quadratic effect (p<0.05) was observed for yolk weight, with an estimated maximal inclusion level of grape pomace flour of 4.18% to obtain the highest yolk weight. A quadratic effect (p<0.05) was also observed on yolk pigmentation, with an estimated minimal level of 3.2% for this parameter. The minimal inclusion of 3.2% of grape pomace flour in quail diets influenced the egg yolk pigmentation, demonstrating its efficiency as a pigmentation additive

Alterações hematológicas em pacientes com dengue Hematological abnormalities in patients with dengue

Dengue é uma doença negligenciada de alta morbidade e mortalidade em crianças e adultos, ocorrendo principalmente em regiões tropicais e subtropicais. O objetivo desse trabalho foi avaliar as alterações hematológicas de pacientes com quadro clínico de dengue. Foram estudados 543 prontuários de atendimentos referentes à epidemia pelo vírus tipo 3, ocorrida no ano de 2007, em Campo Grande, Mato Grosso do Sul. Houve predomínio de casos de dengue clássico (90,2%), com quadro clínico leve sem complicações. As principais alterações hematológicas observadas foram a leucopenia (68,3%), plaquetopenia (66,5%), linfocitopenia (67,2%) e presença de linfócitos atípicos (67%). A febre hemorrágica do dengue apresentou plaquetopenia mais prolongada e maior número de linfócitos atípicos, as demais alterações hematológicas apresentaram evolução diária semelhante às encontradas no dengue clássico. As alterações hematológicas observadas no dengue apresentaram-se de acordo com a evolução clínica e gravidade da doença.<br>Dengue is a neglected disease with high morbidity and mortality among children and adults that occurs mainly in tropical and subtropical regions. The objective of this study was to evaluate hematological changes in patients with clinical manifestations of dengue. Medical records relating to 543 cases of dengue virus 3 that occurred during the 2007 epidemic in Campo Grande, Mato Grosso do Sul, were studied. Cases of classic dengue predominated (90.2%), with mild clinical manifestations lacking complications. The main hematological findings were leukopenia (68.3%), thrombocytopenia (66.5%), lymphocytopenia (67.2%) and atypical lymphocytes (67%). In dengue hemorrhagic fever, thrombocytopenia was more prolonged and the number of atypical lymphocytes was higher, while the other hematological abnormalities presented daily evolution similar to those in classic dengue. The hematological changes observed in dengue present according to the clinical course of the disease and its severity
