The onion (Allium cepa L.) belongs to the family Alliaceae, and the second vegetables in economic importance. It horticultural culture of high relevance, in central-south and in the far south, is highlighting the states of São Paulo, Rio Grande do Sul, Santa Catarina and Parana. The bulbificacion only begins when the combination of the determinants of bulbificacion (photoperiod and temperature) of each cultivar is reached. It Can be grown in tropical regions with the use of vernalization of the bulbs. The objective of this study is to identify the efficiency in the production of seed, onion depending on the cut or not the bulb before the period of vernalization. The analysis of the variables consisted: humidity; number of seeds; mass of seeds for umbel; umbels number; number of seeds for umbel; total number of flowers and of fecundated flowers; number of seeds for capsule; total mass of seeds; emergency percentage; vigor percentage; index of emergency speed and mass of 100 seeds humidity; number of seeds; mass of seeds for umbel; umbels number; number of seeds for umbel; total number of flowers and of fecundated flowers; number of seeds for capsule; total mass of seeds; emergency percentage; vigor percentage; index of emergency speed and mass of 100 seeds, using the cultivars Baia Periforme and Texas Grano. The experimental design was randomized blocks with four replicates, there was 80 plants for replicate, each parcel was conduced with 20 plants distributed in 4 lines of 5 plants with spacing of 20cm between plants and lines which was avaliated the 6 central plants. The seeds production not variated between cultivars Texas Grano e Baia Periforme. The cultivar Texas Grano showed seeds with more physiological quality. The cut or not cut of the bulbs not changed the physiological quality of the seeds. But utilization of whole bulbs resulted more yield of seeds with more flowers number and fertilized flower in Baia Periforme, more value of the total mass of seeds, number of seeds by plant and number and mass of seed by umbel in two cultivars.

To stimulate the bone callus development process from distal third of radius, 24 adult mongrel dogs used were from both sexes. These dogs were separated in two experimental groups of 12 animals each, named control and treated, divided in 4 moments (M1=15 days; M2=30 days; M3=45 days; M4=60 days), who underwent were performed surgical fractures. In treated group, it was performed bone perforations on proximal and distal edges, craniolateral and mediolateral to the fracture site. At the end of each moment, control and treated animals were evaluated by radiography, histology, and bone mineral densitometry (BMD) was determined on fracture site. According to the radiographic data of treated dogs, it was verified on days 15 and 30 more intense bone regeneration than control group. During M3 and M4, it wasn't detected any difference in bone reparation process betweencontrol and treated groups. In densitometric study, BMD values were greater in treated animals than in control dogs. Histological studies revealed at 15 and 30 days chondrocyte hyperplasia and initial endochondral ossification on drilled limbs; control group showed sustainment connective tissue and initial chondrocyte hiperplasia. At M3 and M4 of the treated group, were verified development and remodeling of periosteal callus in more advanced phases when comparing with limbs from control group. It can be concluded that using perforations enhances blood flow supply and activation of osteogenic cells on fracture site, stimulating the beginning of fracture consolidation process.

The present study aimed to obtain information about the uterine inflammatory response (number of polymorphonuclear neutrophilic granulocytes - PMNs) in bitches after artificial insemination (AI) and identify the uterine microflora present after the following treatments: insemination using semen with extender (n=6), insemination with fresh semen (n=6) and no inseminated (n=6). The percentage of PMNs on the endometrial surface and within histological sections was evaluated together with the presence of aerobic bacteria in the uterine lumen. For endometrial cytology, there was no significative difference on the number of inflammatory cells between bitches not inseminated (3.05 ± 1.74 PMNs) and those inseminated with fresh semen (3.55 ± 1.51 PMNs); There was a significative difference in both groups compared to the inseminated with semen plus extender (7.80 ± 1.67 PMNs) (p<0.05). Histology showed that there was no significative difference on the number of inflammatory cells between bitches not inseminated (87.72 ± 35.2 PMNs) and those inseminated with fresh semen (122.97 ± 43.31 PMNs); however, it was observed differences in both groups compared to those inseminated with semen plus extender (171.94 ± 42.74 PMNs) (p<0.05). Eight animals, randomly distributed in the groups, showed the presence of Staphylococcus sp and Proteus sp., in the microbiological exam. The extender for semen, with Tris, is a potent inducer of uterine inflammation, and positive uterine cultures may be obtained during estrus without inflammation or uterine infection.

O presente trabalho teve por objetivo a avaliação da ação dos instrumentos nas paredes do terço apical do canal radicular a 1 e 3mm do CRT, em incisivos inferiores, após preparo com limas NiTi-Flex em rotação alternada, e contínua pelo uso dos sistemas de NiTi: K3, Race, Protaper. Para avaliação da limpeza se utilizou cortes histológicos, na qual a luz do canal foi dividida em quatro quadrantes de acordo com a face (DL, DV, ML, MV). Os resultados mostraram que de modo geral, os melhores resultados foram encontrados para a rotação alternada, sendo seguido pelo sistema Protaper (p<0,05). Os piores resultados foram encontrados para K3 (62,5% sujos), não havendo diferenças estatísticas àqueles encontrados para o sistema Race (45%). Na avaliação dos quadrantes, o mésio-lingual foi considerado o mais sujo para os dois níveis avaliados (p<0,05). Ao final, foi observado que nenhuma das técnicas testadas foi capaz de limpar com efetividade as paredes dos canais radiculares de incisivos inferiores.

Belém, Pára, Brasil, apresenta taxas de mortalidade por câncer de colo uterino bastante elevadas, justificando-se a análise da confiabilidade e validade da causa básica do óbito declarada. Selecionou-se declarações de óbito de residentes de Belém, de 1998-1999, com causa básica de morte neoplasia do colo, corpo e porção não especificada do útero e aquelas que mencionavam essas neoplasias em qualquer linha do atestado, totalizando 188 declarações de óbito. Efetuou-se nova codificação para análise da confiabilidade, aferida pela concordância simples e pela estatística kappa. A causa básica do óbito, após revisão de prontuários médicos e/ou laudos histopatológicos, foi considerada como padrão-ouro para análise da validade de critério, através do valor preditivo positivo. Observou-se concordância simples de 94,0% e kappa de 0,87, sugerindo alta confiabilidade na codificação da causa básica câncer de útero no sistema oficial. Na análise da validade, confirmou-se 120 das 127 originais como colo de útero, três das quatro codificadas como corpo de útero e 18 das 48 classificadas como porção não especificada. Registrou-se aumento de 11,2 % nas neoplasias de colo uterino e redução de 62,5% nos óbitos de porção não especificada do útero.
