The objective of this work was to evaluate the progress of the areolate mildew of cotton under different soil cover and spacing conditions. The experiment was carried out using randomized blocks and a 2 × 3 factorial design, with two spacings (0.45 m and 0.90 m) and three soil covers (no cover, Pennisetum glaucum and Crotalaria spectabilis) with four replications. The plants were inoculated with R. areola, sixty DAS. A total of 14 evaluations of disease severity were performed. At the lower, middle and upper thirds of plants, a diagram scale with nine levels of severity was used and the resulting data were converted into the AUDPC. Gompertz, logistic, and monomolecular mathematical models were tested in the disease severity curves for each third. Agronomics characteristics were evaluated as well. Significant differences of AUDPC were found for the cotton plants thirds, and the middle third was the highest AUDPC. Significant difference for the lower and upper thirds, whose AUDPC were highest on 0.90 m spacing, was observed too. The disease progress curves of the thirds did not fit the tested models. Significant results to the both covers situations, where the treatments grown on crotalária cover and without cover had highest AUDPC, were evidenced. The treatments with C. spectabilis cover were taller than other treatments. Significant data were observed for the cover crops used and in the treatments grown at 0.90

Abstract: O objetivo deste trabalho foi avaliar por meio do triplex doppler as varia es dos índices de resistividade (IR) e pulsatilidade (IP) da artéria hepática (AH) de c es adultos saudáveis em períodos pré e pós-prandiais. O grupo amostral foi composto por quatorze c es sem ra a definida, sendo nove fêmeas e cinco machos com peso entre seis e dezenove quilos e quatro e dezesseis quilos, respectivamente. Previamente aos exames ultrassonográficos, os animais foram submetidos a 24 horas de jejum e, para os exames pós-prandiais, foram alimentados com leite ou ra o comercial. Utilizou-se o ultrassom Philips HDI 4000, munido de um transdutor microconvexo (5-8MHz). Dividiram-se as mensura es dos IR e IP da AH em três tempos: T0 (período pré-prandial), T1 (trinta minutos pós-prandial) e T2 (noventa minutos pós-prandial). N o houve diferen a estatística quando comparadas as médias de IR e IP da AH entre T0 e T2. No entanto, ambos os índices foram significativamente menores no T1 quando comparado com os outros períodos de análise, comprovando aumento de fluxo sanguíneo na AH trinta minutos pós-prandial. O uso do triplex doppler da AH possibilitou mensura es do fluxo sanguíneo pré e pós-prandial, sendo uma técnica importante para estabelecer parametros comparativos entre homeostasia metabólica e diferentes estados fisiopatológicos hepáticos. PALAVRAS-CHAVES: Artéria hepática, c es, índice de resistividade, índice de pulsatilidade, ultrassonografia. The aim of the current study was to evaluate the resistivity index (RI) and pulsatility index (PI) of hepatic artery (HA) by Triplex Doppler in health adult dogs on pre and postprandial periods. The experimental group was formed by 14 mongrel dogs, 9 females and five males, weighing 6-19 kg and 4-16 kg, respectively. The animals were previously prepared, remaining 24 hours of starvation, and feeding with milk or pellet show food to perform posprandial analysis. The ultrasound PHILIPS HDI 4000 equipped with a micro convex transducer (5-8MHz) was used. The RI and PI measurements of HA were performed on tree times: T0 (pre-prandial period), T1 (30 minutes postprandial) and T2 (90 minutes postprandial). There are no statistical differences between T0 and T2 when compared RI and PI of HA. However, both indices were significantly diminished on T1 in relation with T0 and T2, which represents an increase of AH blood flow 30 min postprandial. The employment of HA Triplex Doppler improves the blood flow evaluation pre and posprandial and can be one important technique to establish comparative parameter to distinguish between hepati

Abstract: orbital injuries with a foreign body may result in severe structural and functional damage to the eye or orbital contents. management and prognosis depend on the composition and location of the foreign body and whether there is secondary infection. metallic objects and glass are the most frequently encountered and well-tolerated, whereas organic foreign bodies can elicit an inflammatory reaction and lead to serious complications. despite the modern imaging methods, it is often difficult to identify and locate organic intraorbital foreign bodies. this paper presents a review of nine cases of impacted foreign bodies in the orbital region and discusses the diagnosis and treatment of this kind of injury. the following data were collected: age, gender, etiology of injury, occurrence of fracture, anatomical location of fracture, type of object, signs and symptoms, type of imaging exam used, approach, transoperative complication and occurrence of death. foreign body injuries in the orbital region can be treated with a combination of clinical suspicion, basic knowledge and diagnostic tests and depend on the skill and experience of the surgeon, thereby decreasing the surgical risk of iatrogenic injury in relation to the inherent risk of retaining an organic intraorbital foreign body.

Abstract: Citral (CIT), which contains the chiral enantiomers, neral (cis) and geranial (trans), is the majority monoterpene from Lippia alba and Cymbopogon citratus. The present study aimed to evaluate CIT for antinociceptive and anti-inflammatory activities in rodents. Antinociceptive and anti-inflammatory effects were studied by measuring nociception through acetic acid and formalin tests, while inflammation was verified by inducing peritonitis and paw edema with carrageenan. All tested doses of CIT had significant protection (p<0.001) against acetic acid (0.8%) induced nociceptive behavior and the effects were also similar to morphine while formalin induced nociception was significantly protected (p<0.05) only at higher dose (200 mg/kg) of CIT in the first phase of the test. CIT significantly reduce (p<0.001) nociceptive behavior emanating from inflammation in second phase at all the doses.The pretreatment with CIT (100 and 200 mg/kg) significantly reduced the paw edema induced by carrageenan. Moreover, systemic treatment with CIT (100 and 200 mg/kg) significantly reduced (p<0.001) the leukocyte migration in the carrageenan-induced migration to the peritoneal cavity. Our investigation shows that CIT possess significant central and peripheral antinociceptive effects. It was also verified an anti-inflammatory activity. All together these results suggest that CIT might represent important tool for treatment of painful conditions.

Abstract: Objetivo: analisar a rela o entre a idade materna e a ocorrência de resultados perinatais adversos na popula o do Rio Grande do Norte. Métodos: foram analisados os registros oficiais de 57.088 nascidos vivos no Estado do Rio Grande do Norte no ano de 1997. Os dados foram obtidos do Sistema de Informa o sobre Nascidos Vivos do Ministério da Saúde. A popula o estudada foi dividida em Grupos I, II e III, segundo a faixa etária materna: 10 a 19, 20 a 34 e 35 anos ou mais, respectivamente. As variáveis analisadas foram: dura o da gesta o, peso ao nascer e tipo de parto. A análise estatística foi realizada utilizando-se o teste chi2. Resultados: observamos uma maior incidência de parto pré-termo no Grupo I (4,3 %), em compara o ao Grupo II (3,7%) (p = 0,0028). A taxa de cesariana foi menor nos Grupos I e III, em compara o ao Grupo II (p<0,0001). Evidenciamos freqüência significativamente maior de recém-nascidos de baixo peso nos Grupos I (8,4%) e III (8,3%), quando comparados ao Grupo II (6,5%) (p<0,0001). Conclus es: a gravidez nos extremos da vida reprodutiva esteve associada com maior freqüência de parto pré-termo e baixo peso ao nascer, entretanto, com rela o ao tipo de parto, foi observada maior freqüência de parto normal do que no grupo de gestantes com idade entre 20 e 34 anos.
