Abstract: inventories provide information on the state of biodiversity at a site or for a geographic region. species inventories are the basis for systematic study and critical to ecology, biogeography and identification of biological indicators and key species. they also provide key information for assessments of environmental change, for natural resource conservation or recovery of degraded ecosystems. thus, inventories play a key role in planning strategies for conservation and sustainable use. this study aimed to inventory the fauna of water beetles, larvae and adults, in two mountainous regions in the state of s?o paulo, in serra da mantiqueira (parque estadual de campos do jord?o and pindamonhangaba region) and in serra do mar (santa virgínia and picinguaba divisions) as well as to generate information about the habitats used by the different genera recorded. specimens were collected in lotic and lentic systems, between the years 2005 to 2010. in total 14,492 specimens were collected and 16 families and 50 genera of coleoptera were identified. this study in mountainous regions showed a significant portion of the faunal composition of south america and the state of s?o paulo. the composition of the fauna, in terms of richness and abundance by family, indicated the predominance of elmidae, followed by hydrophilidae and dytiscidae. despite the diversity found, the results of estimated richness indicated the need for additional sampling effort for both regions, since the curves of estimated richness did not reach an asymptote, suggesting that new species can be found in future surveys.

Abstract: in order to define technological alternatives foward delaying deterioration of passion fruit (passiflora edulis sims f. flavicarpa deg.) seeds during storage, physiological studies were performed through varied seed water content and environmental temperature. the experiments were conducted at the seed analysis laboratory of the escola superior de agricultura luiz de queiroz - usp, from july 2002 through august 2003, with yellow passion fruit seeds produced in mogi mirim/ sp, through random pollination among iac 270 series hybrids. following seed mucilage removal, the initial moisture degree of the lot was determined and the representative sample of the treatment with the highest water content studied (31%) was obtained concurrently; the remaining seeds were dried in an air-circulating oven at 30oc ± 3oc to achieve other treatments regarding the intended water contents (27%, 21%, 17%, 11% and 7%). further, the treatments - corresponding to different moisture levels - were stored in controlled-temperature chambers at 10 oc, 15 oc and 20 oc. previous to storage and 35, 70, 105, 140, 175, 210, 245, 280, 315 and 350 days later, the seeds were submitted to quality assays. the results indicate that the combination between 7% moisture degree and 10oc temperature overcomes the remaining ones, favoring the maintenance of the physiological potential of passiflora edulis sims f. flavicarpa deg. seeds.

Abstract: callus from lycopersicon esculentum x l. peruvianum interespecific hybrids cultured in vitro lost their morphogenetic abilities after two years. an attempt has been made to recover the organogenesis of those callus, using 5 x 5 and 3 x 3 diallelic combinations between indolacetic acid (iaa) and 6-benzyl-adenin (6-ba). mineral salts and vitamins of the ms medium (murashige & skoog), were used, added with sucrose (3%) and agar (0.8%). culture medium ph was kept at 5.5. the 5 x 5 diallelic treatments were incubated under the following conditions: day temperature = 25 ± 3°c; day length = 16 hours; light intensity = 600 lux. the 3 x 3 diallelic treatments were kept at the same conditions of daylight and temperature but at 2000 lux light intensity. callus development and shoot formation were graded from 1 to 5, 30 days after inoculation, shoot number and height were also evaluated. in the 5 x 5 diallelic experiment, it was observed a low number of differentiated plants. the best combinations for callus development have been 0.5, 2.5 and 5.0μm of iaa with 2.5μm of 6-ba, respectively. however in the 3 x 3 diallelic experiment, it was recorded a high frequency of shoot formations and the most efficient treatments were the 25.0 and 50.0μm concentrations of 6-ba, without any auxin. it was also observed the influence of environmental condi-tions (mainly light intensity) on the process.

Abstract: results are reported from a study on drug use in treatment of children with pneumonia in a pediatric hospital in the city of fortaleza, northeastern brazil. there were 171 out-patients; prescription details were obtained for 149. the most commonly prescribed antimicrobial drug was procaine penicillin, accounting for 33% of antimicrobial prescriptions, followed by benzathine penicillin (31%), ampicillin or amoxicillin (12%), and cotrimoxazole (8%). benzathine penicillin was frequently given with other drugs, but was the sole antimicrobial agent for 31 children. compliance with antimicrobial treatment was 52% overall and was higher for the injectables. prescription patterns varied from child to child, and children were often prescribed more than one antimicrobial in the same or repeat prescriptions; combining this information with compliance, 81 (54%) of the children were estimated to have received 5 or more days of appropriate antimicrobial treatment for pneumonia. this percentage is not high, and five days were often reached after using more than one antimicrobial and after repeat visits. the authors concluded that the need remains for simple antimicrobial regimes, attractive to comply with, that can be expected to be consistently used. other drugs were chiefly analgesics and bronchodilators.
Uso da aspira o manual a vácuo na redu o do custo e dura o de internamentos por aborto incompleto em Fortaleza, CE, Brasil
Fonseca Walter,Misago Chizuru,Fernandes Lucília,Correia Luciano
Revista de Saúde Pública , 1997,
Abstract: INTRODU O: O uso de aspira o a vácuo (AV) no tratamento do aborto incompleto é prática bastante difundida em países desenvolvidos. Vários estudos nesses países indicam que o uso da técnica de aspira o manual a vácuo (AMV) pode conservar recursos do sistema de saúde e melhorar a qualidade do tratamento do aborto. No Brasil, o uso da AMV é procedimento de rotina nos hospitais e clínicas privados. Entretanto, na maioria dos hospitais da rede pública é utilizada somente a técnica de dilata o e curetagem (D&C). METODOLOGIA: Foram utilizados métodos de avalia o rápida para estimar a varia o do custo médio do tratamento e dura o da estadia hospitalar, em um grupo de 30 pacientes admitidas com aborto incompleto em hospital público de Fortaleza, CE (Brasil). Participantes foram alocadas, randomicamente, em um dos dois grupos de tratamento investigados (AMV ou D&C). RESULTADOS E CONCLUS ES: Os resultados sugerem que o uso da AMV, em substitui o a D&C, no tratamento do aborto incompleto, pode reduzir em até 41% o custo médio do tratamento e em 77% o tempo médio de hospitaliza o. Recomenda-se a realiza o de estudos confirmatórios, como também que se aprofunde os conhecimentos sobre a percep o do aborto e seu tratamento por parte do pessoal de saúde e da popula o feminina.
Laryngeal sequelae due to accidental inhalation of anhydrous ammonia
Cruz, Walter Paiva,Fonseca, Maria Concei??o Bela da
International Archives of Otorhinolaryngology , 2009,
Abstract: Introduction: Anhydrous Ammonia (AA) is a caustic compound commonly used in the industry that can cause burns, even with brief contact. As with other alkali burns, the early washing to remove the AA from burnt areas is crucial to limit tissue damage. The concentration of toxic agent and duration of its contact determine the degree of skin and mucosa destruction. A tanker truck carrying AA (NH3) fell off a highway, and released a dense cloud of AA gas. Fifty-four people inhaled the gas and after ninety days, three people were still experiencing hoarseness and were examined. Case Report: We assessed three patients with laryngeal sequelae due to AA inhalation burn. We found a case of hyperemia and edema, one case of granuloma of the posterior third portion of the left vocal cord, and one case of vocal cord adhesion. Necropsy findings are commented both macroscopically and microscopically. The sequelae and the best treatments for them are discussed herein.

Arquivos Internacionais de Otorrinolaringologia , 2009,
Abstract: Introdu o: Am nia Anidra (AA) é um cáustico comumente usado na indústria que, acidentalmente, pode causar queimaduras, mesmo com um breve contato. Como ocorre com outras queimaduras por álcalis, a lavagem precoce remove a AA das áreas afetadas e é fundamental para limitar a les o tecidual. A concentra o do tóxico e a dura o do contato determinam o grau de destrui o da pele e das mucosas. Um caminh o carregado de AA (NH3) capotou na estrada, liberando densa nuvem de gás AA. Cinquenta e quatro pessoas inalaram o gás e, depois de noventa dias, três pessoas ainda apresentavam rouquid o, sendo por nós examinadas. Relalto do Caso: Avaliamos três pacientes com sequelas laríngeas por queimadura após inala o de AA. Encontramos um caso de hiperemia e edema, um de granuloma de 1/3 posterior de prega vocal esquerda e um de sinéquia de pregas vocais. S o comentados os achados de necropsia, tanto macro quanto microscopicamente. S o discutidas as sequelas apresentadas, bem como os melhores tratamentos.

Cadernos de Saúde Pública , 1998,
Abstract: No Brasil, a indu o do aborto é legalmente permitida somente quando necessária para salvar a vida da mulher ou quando a concep o ocorreu de estupro. Apesar das restri es legais, morais e religiosas, a indu o do aborto é amplamente praticada. Com o objetivo de identificar as características do aborto incompleto nas mulheres admitidas na maternidade pública de Florianópolis, foram entrevistadas 620 mulheres, entre 1o de julho de 1993 e 30 de junho de 1994. Com base em dados coletados por meio de questionário estruturado, s o apresentadas características sócio-demográficas, reprodutivas e médicas dos abortos, classificados como certamente provocados, possivelmente provocados e espontaneos. Entre os 141 casos de aborto provocado, cerca de 50% das mulheres reportaram uso isolado do Cytotec (misoprostol), ou deste associado a outro método abortivo. Os resultados revelam que na popula o estudada a indu o do aborto é prática comum entre mulheres jovens, solteiras ou sem parceiro estável, de bom nível de escolaridade e n o usuárias de métodos anticonceptivos. Foi também registrada uma redu o do número de complica es graves relacionadas ao aborto provocado admitido ao hospital.
