Ectrópio palpebral: Características e relação com alterações óculo-palpebrais

Objective: To evaluate the gender and the characteristics of the ectropion carriers in our region. Methods: A retrospective study was done evolving 112 ectropion carriers. The sex, race, eyelashes alterations (trichiasis and distichiasis), anterior and posterior blepharitis, conjunctival redness, íris color and pterygium presence were evaluated. Gender data were correlated to ectropion classification (involutional, cicatricial, mechanic or paralytic) and submitted to statiscal analysis. Results: The eyelid ectropion occurred more between 71 and 80 years old.The involutional ectropion was the most frequently observed (66,07%), followed by the cicatricial, mechanic, associated types and paralytic. The majority of the patients were male (70,53%), with White skin. Trichiasis (21,42%) and distichiasis (4,46%) were associated to the ectropion eyelid and mainly in the involutional ectropion carriers. Half of the sample had blepharitis and the majority of the patients had red eye (60%) and brown iris (63,39%). Perygium was absent in the majority of the patients. Conclusion: The involutional ectropium is the most frequently observed in our region, mainly in elderly, male, White skin, brown iris and associated to trichiasis, blepharitis and red eyes.

Situação vacinal infantil e características individuais e familiares do interior de São Paulo

The aim of this study was to describe and analyze individual and family characteristics of children and those of health services, as well as their relationship with the immunization status for different kinds of vaccines and doses. Three sources of information were used: records from the Municipal Health Information System, immunization charts, and interviews using closed-ended questions. The families interviewed still had one or two growing children; caretakers were usually young unemployed mothers with easy access to health services. Around 30% of them were not instructed on the vaccine being given, its reactions or when to return for the next shot. The greatest levels of tardiness occurred with the vaccines against measles (6.3%) and Haemophilus influenzae B (4.2%). It was possible to observe that tardiness or absence of vaccinations seem to have a stronger relationship with service characteristics than with population characteristics.

Características ultraestruturais do segmento abdominal da aorta de rato albino

The objective of the present research was to investigate the ultrastructural peculiarities of the aortic wall of the rat. Seven young adult rats were used, from which fragments of the infrarenal abdominal aorta were collected. After collection, the vascular segments were fixed and sent for analysis by scanning electron microscope. The elastic lamellae appear interposed with smooth muscular fibers; this pattern was verified mainly at the medial layer structure. Among the mural elements a well defined interrelationship was established through connective lamellae of the arterial wall. The collagen lamellae mainly provided anchoring among the elastic and smooth muscular constituents. The intimal layer showed special ultrastructural features, such as a non-continuous inner elastic lamina presented in certain sites of the vascular wall, followed by endothelial pores. This mural pattern of the abdominal aorta provided support to vascular functions such as shrinkage among the laminar composition of the arterial layers, also acting in mechanical properties of the vascular wall, such as viscoelasticity and contractility - essential actions to blood vessel hemodynamics.

Influência das propriedades de granulados de lactose nas características físicas dos comprimidos

The compaction behavior of powdered solids used in tablets can be dominated by the physical-chemical properties of the excipients because, frequently, they are present in much larger amounts than the drug in tablet formulation. The aim of this study was to evaluate the influence of the size of lactose granules on the physical characteristics of tablets produced in punches of various diameters, since this relation has not been explored in the literature. Granules were produced in several sizes by wet granulation and compressed in punches of different diameters by applying different forces. Size distribution, apparent density and flow of granules were evaluated, as well as the physical characteristics of the tablets (weight, friability, hardness and disintegration time). The results indicate that in situations where excipient characteristics predominate due to low drug content, as in the 7 mm punch, the selection of granule size is important for the mechanical strength of tablet. On the other hand, with the 9, 11 and 13mm punches, it was possible to produce strong tablet from all sizes of granules.

Características fenotípicas de 44 progênies de espinheira-santa (Maytenus ilicifolia Mart. ex Reiss) cultivadas no município de Ponta Grossa, PR

Due to the confirmation of its medicinal properties, the demand and the area planted with 'espinheira-santa' have been increasing. However, there are no sources of propagation material with known characteristics. Progenies of Maytenus ilicifolia Martius ex Reiss (espinheira-santa), originating from Southern Brazil have been analyzed, and currently comprise a germplasm inventory for the species. Studies included the assessment of in natura growth features (height and production of biomass canopy) and plant chemistry (lignin, phenols and mineral element contents), and targeted the creation of a data base, characterizing populations/progenies to be used in future selection and breeding programs of the species. Among the features assessed, were considered desirable the ones related to productivity (high foliar mass to branch mass ratio) and also the absence of thorns on the leaves. High total phenol and tannin content were observed in all the progenies assessed and these features is desirable as long the absence of toxic effects and preservation of the therapeutic quality of the plant medicinal elements produced can be proved.

Influência das propriedades de granulados de celulose nas características físicas dos comprimidos

The compaction behavior of powdered solids can be strongly influenced by the physicochemical properties of excipients because they are frequently present in the tablet in larger amounts than the drug itself. The aim of this study was to assess the influence of the granule size of the cellulose on the physical characteristics of tablets produced in punches of different diameters, since this relation has never been explored in the literature. Granules of several sizes were produced by wet granulation and compressed in punches of various diameters by applying different forces. Size distribution, apparent density and flow of granules were assessed, as well as physical characteristics of the tablets (weight, hardness, friability and disintegration time). Reducing the granule size resulted in tablets of adequate crushing strength and fast disintegration; moreover, it allowed tablets to be produced without the need to use forces near the upper limit of the press, thus avoiding premature wear on the tabletting machine. Thus, once a suitable size for a given tablet formulation has been chosen, the granule size selected has been shown to determine the crushing strength of the tablet.

Características reológicas e sensoriais de bebidas lácteas funcionais

This research studied the effects of the independent variables whey protein concentrate - WPC (3.0; 3.5; 4.0%), skimmed milk powder - SMP (4.0; 5.0; 6.0%), and isolated soy protein - IPS (1.5; 2.0; 2.5%) on the rheological and sensorial characteristics of functional dairy beverages. In all tests 7% of sucrose was added to the ingredients. The rheological parameters were obtained in duplicate at the temperature of 10° C using a cone and plate rheometer, and fitted to the Power law model. The samples revealed a non-Newtonian fluid behavior both in the upward and downward curves, typical of a tixotropic fluid. The dairy beverages were submitted to a sensory analysis by a group of fifty untrained tasters who used a hedonic scale of nine points, the extremes being 1 - disliked extremely and 9 - liked extremely, in order to evaluate the following parameters: general acceptability; appearance and color; consistency; taste and aroma. The dairy beverage produced with 3% WPC, 6% SMP and 1.5% IPS, (treatment 3), was the one that obtained the best average score for those attributes and was preferred by the tasters. The variables SMP and IPS and the interaction between WPC and SMP presented a positive effect on the sensory consistency attributes: the higher amount of those ingredients in the formula the more the tasters liked the consistency.

Nitrogênio em cobertura e molibdênio via foliar em feijoeiro de inverno no sistema plantio direto II - Características agronômicas e produtividade

Nitrogen is the nutrient most uptaken by common bean plant, and molybdenum besides its importance to N fixation process, it is associated to N metabolism. The objective of this work was to evaluate, on common bean crop Pérola cultivar, the effect of N levels application at side dressing (0, 30, 60, 90 and 120 kg ha-1) as well as the leaf application of Mo (0, 80 and 160 g ha-1) at development stadium V3 or V4 under no tillage system. The experimental design was the randomized blocks with 30 treatments and 4 replications. The research was conducted in Selviria-MS on soil previously cropped with corn. The application of nitrogen levels at side dressing provided increasing on dry mass weight, number of pod and seeds per plant and grain yield, in the 2004; the Mo application at V3 or V4 stadia did not effect the production components and grain yield; as well as different doses of Mo depended on the N application at side dressing, in the 2004.

Linhagem materna: Qual a sua influência em características pré e pós desmama em bovinos da raça Nelore?

The present work had as objective to evaluate the effects of the introduction of the maternal lineage (Lc), representing the mitochondrial inheritance, in the model of genetic evaluation on birth weight (BW), weight for 120 days (W120), weaning weight (WW), weight at 12 month (W12), weight at 18 month (W18), weight gain from weaning to 18 month (WG18), scrotal perimeter (SP) and temperament (TEMP) of a Brazilian Nelore herd. Two models had been used for raise a comparison among of estimates the (co)variances components and genetic parameter, been the first equal one to currently used in the genetic evaluations of this herd, and second included the random effect of maternal lineage. Amongst the analyzed characteristics, the maternal lineage effect was significant (P<0.05) for W18 and SP only it, where this effect was responsible for 3% and 7%, respectively, of phenotypic variance could be explained by Lc effect. For besides characteristics, however not significant, this effect was responsible for 1% and 9% of phenotypic variance.

Características de carcaça de cordeiros alimentados com grãos e subprodutos da canola

The aim of this work was to evaluate the introduction of 8% grains and by-products (meal or cake) of canola in the diets of lambs. To evaluate quantitative carcass characteristics, 24 Santa Ines lambs were used in a completely randomized design. Diets with averages of 15.4% of CP in DM and 80.2% of TDN were composed for 40% Tifton hay and 60% concentrate based on corn grain, soybean meal, whole grain canola, canola meal, canola cake and mineral mixture. The use of whole grains and by-products of canola in the diet of lambs finished in feedlot did not influence (p > 0.05) quantitative carcass characteristics. For cut dressing in relation to the CCW, no effect was observed for the analyzed variables among treatments. It was concluded that the introduction of grains and by-products of canola allow for satisfactory results, and could be recommended in the formulations of lamb diets.
