Efeito da icterícia obstrutiva na cicatriza o de anastomoses col nicas em ratos
Azevedo Marcelo Almeida,Féres Omar,Rocha José Joaquim Ribeiro da,Aprilli Francisco
Acta Cirurgica Brasileira , 2002,
Abstract: INTRODU O: A deiscência de anastomoses é uma das complica es que ocorre em pós-operatórios de cirurgias do aparelho digestivo, aumentando a morbi-mortalidade de pacientes. No cólon, particularmente, essa complica o tem maior gravidade pela presen a de fezes dentro da cavidade peritoneal, o que pode levar a peritonites críticas. OBJETIVO: Avaliar a cicatriza o de anastomoses col nicas em ratos na vigência de icterícia obstrutiva. MéTODOS: Foram utilizados 23 ratos divididos em dois grupos. Grupo I (controle): n=10 e Grupo II (obstruído): n=13. No início do experimento foram realizadas ligadura e sec o do colédoco. Após sete dias, realizados sec o e rafia do cólon distal. No 14masculine dia de experimento avalia-se condi o local da cavidade e resseca-se segmento da anastomose para estudo bioquímico. No grupo II ou Controle (n=10) apenas n o se realiza a ligadura de colédoco obedecendo todas as outras condi es do grupo I. RESULTADOS: Foi observado maior número de complica es no grupo Obstruído (4/13) do que no Grupo Controle (0/10), mas que foi sem significancia estatística e também que a variancia dos valores da dosagem de hidroxiprolina no grupo Obstruído foi maior que no grupo Controle mesmo apresentando média de valores semelhantes estatisticamente.

Memórias do Instituto Oswaldo Cruz , 1990, DOI: 10.1590/S0074-02761990000200004
Abstract: rhesus monkeys (macaca mulatta) were infected subcutaneously with 1.0 x 10**4 to 1.5 x 10**4 metacyclic trypomastigotes of trypanosoma cruzi (colombian strain). parasitological and immunological parameters were evaluated in these animals for periods of 1 month to over 3 years. a chagona was observed between the 3 rd and the 13th day after infection (a.i) and patent parasitaemia between the 13th and 59th day a.i.. thereafter, parasites were demonstrated only by haemoculture and/or xenodiagnosis. circulating specifc igm and igc antibodies were observed as early as in the 2nd week a. i. igg levels persisted until the end of the expriment, but igm antibodies were detectable nine months a. i. haematological alterations comprised leucocytosis and lymphocytosis. eletrocardiographic alterations were minor and transient, similar to those observe in non-lethal human acute chagas' myocarditis. myocarditis and myositis, characterized by multiple foci of lympho-histiocyte inflammatory infiltrate, were present in monkeys sacrificed on the 41 th, 70th and 76 th day but not in the animal sacrificed 3 years and 3 months a. i.. the results suggest that chagas' disease in rhesus monkeys reproduces the acute and indeterminate phases of human chagas' disease.

Abstract: with the objective to evaluate the performance of broiler chickens subjected to feed restriction (fr), an experiment was conducted in a completely randomized design with factorial arrangement (6 x 2), with six feeding programs, two sexes, four replicates and 15 birds per experimental unit. the used feeding programs were: res-0 (ad libitum), res-1 (day 7), res-2 (days 7 and 14), res-3 (days 7, 14 and 21), res-4 (days 7, 14, 21 and 28) and res-5 (days 7, 14, 21, 28 and 35). each restriction consisted of 24 hours fasting. on day 42, body weight of broilers subjected to programs res-0, 1, 2 and 3 were not significantly different. however, birds subjected to res-4 and 5 programs showed lower body weights (p<0,05) when compared with those from res-0, 1 and 2 programs. no significant differences were observed on feed intake and feed to gain ratios among the various programs, at this age. however, feed to gain ratios during refeeding periods (days 21 to 42 and 28 to 42) were better to birds subjected to feed restriction than those from control group. carcass and special cuts yield were not affected by feeding programs. the most intense feed restriction program (res-5) negatively influenced the protein content of the carcass and the fat content of the carcass were not influenced. the most intensive feed restriction programs negatively influenced the performance of birds.

Revista Brasileira de Geofísica , 2009, DOI: 10.1590/S0102-261X2009000500002
Abstract: the importance of environmental monitoring is clear from the many oil spills that have occurred over the past three decades. this has encouraged both companies and the public sector involved in the prevention and response to these accidents to develop efficient procedures to minimize the damage caused by accidents involving oil spill. this study reviews the history of oil spill accidents in brazil and examines how these events have contributed to the development of technological research through partnerships involving oil companies, government, universities and research institutes, with the emphasis on the amazon coastal zone. as a result, environmental sensitivity indexes (esis) for oil spill have been developed specifically for the amazon coast, where fluvial and marine processes take place in the estuary of the world's largest river system. perspectives on research and emergency response procedures are presented, with the primary objective of conserving the social-environmental diversity of the planet's most important tropical region.

Abstract: the effect of pre-crops on the inoculum potential (ip) of arbuscular mycorrhizal fungi (amf) and yield of cassava was evaluated on a red-yellow podzolic soil in the field. the experiment was carried out at embrapa-centro nacional de pesquisa de agrobiologia (cnpab), seropédica, rj, brazil, in plots with 30 m2 arranged in a randomised block design with four replications. as pre-crops, four legume species were used: canavalia ensiformis, mucuna aterrina, crotalaria juncea and cajanus cajan; and a grass sorghum bicolor (br 005) in relation to plots, without plants. after a grow period of 82 days, at the same plots, cassava stakes were planted, which were grown for eight months. the yield of cassava roots ranged from 12.76 to 17.20 ton ha-1, although no statistical significant effects were found between the treatments. there were 16 amf species identified, and some of them had a significant frequency changement after the growing cycles. the number of infective propagules were significantly increased after sorghum crop in relation to plots without plants. it was showed that identification of plant species capable to increase the ip in the field soils may be a good alternative way to solve the problem of inoculum production to mycotrophic crops in the field.

Revista Brasileira de Ginecologia e Obstetrícia , 2008, DOI: 10.1590/S0100-72032008000200002
Abstract: purpose: to compare two strategies of access to emergency contraception: only information and information with previous delivery of this contraceptive method, and its relationship with the use of this method and the regular use of contraceptives. methods: from august 2004 to january 2005, 18 to 49-year-old volunteers, attended at reproductive health clinics from six brazilian towns were recruited. the subjects were randomly distributed in a group getting information about emergency contraception (control group), or in a group getting information about this method and previous delivery of the contraceptive (medicated group). follow-up visits occurred into four and eight months. person and mcnemar's tests were used for the statistical analysis. results: from the 823 recruited subjects, 407 completed the 8-month-observation period and were the sample analyzed. most of the subjects (61%) did not use the emergency contraceptive. the subjects from the medicated group used more emergency contraceptives (57%) than the ones from the control group (18%), and they did it more precociously, concerning the time since the unprotected sexual intercourse. there was a significant increase of regular use of contraceptives among the subjects who used emergency contraceptives in the medicated group (88% versus 97%) and a statistically nonsignificant decrease in the control group. conclusions: information and previous delivery intensified the access and use of emergency contraceptives, and did not reduce the regular use of contraceptives, including condoms.

ANARUMA FILHO, Francisco;CHIEFFI, Pedro Paulo;CORREA, Carlos Roberto Silveira;CAMARGO, Eide Dias;SILVEIRA, Edilene P. Real da;ARANHA, Joana José Brand?o;RIBEIRO, Manoel Carlos S. Almeida;
Revista do Instituto de Medicina Tropical de S?o Paulo , 2002, DOI: 10.1590/S0036-46652002000600002
Abstract: the occurrence of human toxocara infection was evaluated in three neighborhoods of the periphery of the campinas municipality (jardim santa m?nica, jardim s?o marcos and jardim campineiro) in 1999. forty residences and 138 residents were randomly selected by drawing lots and were submitted to a seroepidemiological survey, which included blood collection for the immunoenzymatic detection (elisa) of anti-toxocara antibodies and a blood count, and the application of a semi-structured questionnaire for the evaluation of epidemiological data. significant levels of anti-toxocara antibodies were detected in 23.9% of the 1999 samples. no significant difference in the frequency of infection according to age was observed. environmental contamination with toxocara eggs was observed in 12.3 and 14.0% of 57 soil samples collected in the same region in december 1998 and july 1999, respectively. univariate analysis and multiple logistic regression of the data obtained from the questionnaires and of the results of the serological tests, suggest a significant influence of socioeconomic variables on the frequency of human infection with toxocara under the conditions prevalent in the study area.

Abstract: The duties of District Corregidors are described in its respective title of the Kingdom’s Ordinances. In spite of the fact that their fundamental action was carried out within the scope of the administration of justice, one can neither ignore nor underestimate its municipal management surveillance role in the municipalities of their District. Therefore, within this framework, one of the obligations of the Corregidors in each of the municipalities was their annual visit. The Auditor Magistrates in the Donee Lands had the same annual visit obligation. In this essay, one studies precisely the historical reach of the Corregidors’ visits that took place in the municipality of Vila da Feira, Feira County, between 1745 and 1766, and its influx in the municipal governance.
