Abstract: this study was aimed to evaluate and compare the pathogenicity of rabies virus isolated from bats and dogs, and to verify the efficacy of a commercial rabies vaccine against these isolates. for evaluation of pathogenicity, mice were inoculated by the intramuscular route (im) with 500micld50/0.03ml of the viruses. the cross-protection test was performed by vaccinating groups of mice by the subcutaneous route and challenged through the intracerebral (ic) route. isolates were fully pathogenic when inoculated by the ic route. when inoculated intramuscularly, the pathogenicity observed showed different death rates: 60.0% for the desmodus rotundus isolate; 50.0% for dog and nyctinomops laticaudatus isolates; 40.0% for artibeus lituratus isolate; 9.5% molossus molossus isolate; and 5.2% for the eptesicus furinalis isolate. mice receiving two doses of the vaccine and challenged by the ic route with the isolates were fully protected. mice receiving only one dose of vaccine were partially protected against the dog isolate. the isolates from bats were pathogenic by the ic route in mice. however, when inoculated through the intramuscular route, the same isolates were found with different degrees of pathogenicity. the results of this work suggest that a commercial vaccine protects mice from infection with bat rabies virus isolates, in addition to a canine rabies virus isolate.

Abstract: antibodies to enterovirus 71 (ev71) were evaluated in s?o paulo state during 1999-2005. the titer of neutralizing antibodies against ev71 was determined by microneutralization assay, and a titer of > 1:8 was defined as indicative of protected immunity. neutralizing antibodies to ev71 were observed in 12.4% (55/442) of sera samples, a low protective rate, suggesting that ev71 infection is uncommon in this region, but that there is a relatively high susceptibility to ev71 related diseases, which is worrying considering the recent asian outbreaks. also, a significant location-specific difference in seropositivity was observed. neutralizing antibodies to ev71 were observed in 8.7% (21/241) of s?o paulo metropolitan area sera samples, and 16.9% (34/201) of the sera samples from other municipalities. a high number of brazilian residents live in country and coastal areas without adequate access to piped water or sanitation. this situation may contribute to the ev71 dissemination in these zones. the analysis of environmental samples could possibly make a valuable contribution to studies on the epidemiology of ev71.

Abstract: objective: to disclose the existence of rooming-in (ri) in public and government contracted private hospitals that offer obstetric beds, in the state of rio de janeiro, brazil, and to examine whether there is any association between ri and another quality care indicator which influences breastfeeding, namely the rate of cesarean section operations performed in these hospitals. method: a survey was made of the existence of ri through a questionnaire sent to the municipal health offices, the information collected being confirmed by telephone with each maternity hospital. the c-section rate data was obtained from the rio de janeiro state health office and divided into 2 groups: "below 40%" and "40% and above". the prevalence ratio was applied to the measurement of the association between the variables. results: a rooming-in rate of 65.2% was found for the state as a whole, with regional variations: a better situation in the capital (84.8%), an intermediate one in the interior (69.9 %), and a worse one in the metropolitan belt (44.2%). the public maternity hospitals revealed a higher rate (89.7%) than that of the government contracted private hospitals (53.3%). a direct relation between the practice of ri and low c-section rates was found in the hospitals. however, this association did not present the same weight in all regions of the state. the lowest proportion of hospitals adopting ri was verified in the metropolitan belt, whereas the highest relative number of hospitals with high c-section rates was observed in the interior. conclusion: it is concluded that to reverse the observed status, government authorities must fulfil their gerencial role within their own health system, as well as in the government contracted private hospitals.

Abstract: OBJETIVO: Conhecer a existência de alojamento conjunto (AC) nos hospitais que possuem leitos obstétricos da rede pública e conveniada do Estado do Rio de Janeiro e verificar se o AC guarda associa o com outro indicador de qualidade de assistência que tem influência sobre o aleitamento materno: as taxas de cesárea (TC) praticadas por esses hospitais. METODOLOGIA: Procedeu-se a um levantamento sobre a existência de AC através de questionário enviado às Secretarias Municipais de Saúde, informa o validada por inquérito telef nico. As TC foram obtidas junto à Secretaria Estadual de Saúde-RJ. Foi utilizada a raz o de prevalência para a medida da associa o entre as variáveis. RESULTADOS: Foi encontrada uma propor o de 65,2% das maternidades com AC, no Estado. Verificou-se rela o direta entre a presen a de AC e baixas taxas de cesárea no conjunto dos hospitais, porém essa associa o n o se confirmou com o mesmo peso em todas as regi es. A menor propor o de hospitais com AC foi verificada no cintur o metropolitano (44,2%), enquanto a maior propor o de hospitais com elevadas taxas de cesárea está no interior (73,1%).

Abstract: this descriptive and correlational study, carried out at a teaching hospital in 2004, aimed to get to know if, in the context of domestic violence, parents use physical violence as an educational practice. semistructured interviews were used to characterize the population, and situations of daily family life to identify parents' attitude in the education process. results: the most vulnerable situation to use physical punishment was disobedience to parents' predetermined orders (40%), followed by the situation when the child steals something (31.7%). the use of physical violence as a disciplinary practice was significant (p=0.020), associated with unemployment. forty percent of the population reported they imposed their will on their child, and 57% mentioned they had been physically punished by their parents in limit-imposing situations. knowledge and reflection on factors involving domestic violence are very important to consolidate prevention programs and which could generate a collective consciousness.

Abstract: in order to evaluate the effects of nightshade coexistence on processing tomato yield, hybrid heinz 9992, an experiment was carried out consisting of two sets of treatments: in the first set, the crop was kept weed free (60 thousands plants ha-1) from transplanting to 15; 30; 45; 60; 75; 90; 105 days and 120 (harvest) days after transplanting (dat); while in the second set, the crop was kept in competition with the nightshade from transplanting until the same dat described for the set of treatments. a randomized block design trial, with three replications and four-row plots was used. height, leaf area, and aerial part dry matter of nightshade was obtained out of 10-plant samples. nightshade leaf area increased until 75 days of tomato coexistence (1,588 dm2 plant-1); height until 60 days of coexistence (85 cm), and the leaf dry biomass until 120 days of coexistence (31.7 g plant-1). the highest (108.6 tons ha-1 or 87.6 % of total production) and lowest (14.2 tons ha-1 or 59%) ripe tomato yields were observed when the coexistence between tomato and nightshade occurred only in the first 15 days or in the whole crop cycle, respectively. in these treatments, the average ripe fruit weights were 58.7 and 38.0 g, respectively. each cm2 of increase in the nightshade leaf area caused a reduction of 0.04 tons ha-1 (r2 = 0.90) on the ripe tomato yield; each cm of increase in the nightshade height reduced the ripe tomato yield in 0.82 tons ha-1 (r2=0.78); and each gram of increase in the nightshade aerial part dry matter reduced the ripe tomato yield in 2.84 tons ha-1 (r2=0.97). the period before interference, allowing up to 5% reduction in tomato yield, was 27 dat; the total period for preventing interference was 46 dat; and the critical period for preventing interference was between 27 and 46 dat.

Abstract: considering the great ecological and sanitary importance of the cyanobacteria and the need of detailed information about these organisms in brazilian water bodies, the present study aims at contributing towards the knowledge of the cyanobacterial flora of five reservoirs belonging to the upper tietê basin, s?o paulo: billings, guarapiranga, jundiaí, pirapora, ponte nova and taia?upeba. in the past several years, these reservoirs have been submitted to severe environmental deterioration and have repeatedly presented cyanobacterial blooms, including those of toxic species. the samples were collected between 1997 and 2003 either with plankton net (20 μm mesh) or van dorn's bottle, and preserved with lugol solution or formaldehyde. some species were isolated and maintained in culture. forty-eight species of cyanobacteria were identified, with predominance of the order chroococcales (58%), followed by the orders oscillatoriales (21%) and nostocales (21%). among the 48 studied species, 17 (35%) were considered potentially toxic. the occurrence and biodiversity of the cyanobacteria in each reservoir depend on the environmental conditions. among the five water bodies, billings reservoir presented the most adequate situation for the development of a greater number of species (34), probably due to its high ph values (around 8). pirapora reservoir on the other hand, with highest conductivity (445.0 μs cm-1) and lowest secchi depth values (0.2 m), presented the lowest cyanobacterial biodiversity (14 species).

Abstract: the present paper describes the relationship between the use of oral contraceptives and arterial blood pressure among women residing in rural, urban and metropolitan areas of rio grande do sul, the southernmost state of brazil. the analysis is based on data from a cross-sectional survey of blood pressure carried out in rio grande do sul, in 1978. in an analysis ofcovariance, controlling forage and quetelet index, the average systolic and diastolic pressures of oral contraceptive users or ex-users were compared to the average pressure of never-users. a positive difference in systolic pressure was observed systematically for all four study strata (rural interior, urban interior, capital and its metropolitan belt), among women using oral contraceptives at the time of interview. the difference was found to be significant (p < 1%) for women residing in the metropolitan belt using oral contraceptives for more than 2 y ears. the effect on diastolic pressure, although generally positive, were smaller and not significant. the research methodology allowed for the association between the use of oral contraceptives and other risk factors to be evaluated. the effect on blood pressure was found to be most intense for women of the lowest educational status residing in the metropolitan belt. for the group of women with a history of hypertension during pregnancy or classified as hypertensive (criteria 140/90) the effect of oral contraceptives was also found to be highly significant (p <1%) - an alteration of over iqmmhg on the average systolic pressure. these results suggest that the use of oral contraceptives brings about a greater increase in systolic pressure in groups of women with normally higher levels of pressure.
