The antimicrobial activity of Curcuma zedoaria (Christm) Roscoe extract against some oral microorganisms was compared with the antimicrobial activity of five commercial mouthrinses in order to evaluate the potential of the plant extract to be incorporated into formulas for improving or creating antiseptic activity. The in vitro antimicrobial efficacy of plant extracts and commercial products were evaluated against Streptococcus mutans, Enterococcus faecalis, Staphylococcus aureus and Candida albicans using a linear regression method to evaluate the microbial reduction obtained in function of the exposure time, considering as effectiveness a 99.999% reduction in count of standardized microbial populations within 60 seconds. The results showed that the antimicrobial efficacy of Curcuma zedoaria (Christm) Roscoe extract was similar to that of commercial products, and its incorporation into a mouthrinse could be an alternative for improving the antimicrobial efficacy of the oral product.

The main goal is to compare the antioxidant potential of rosemary and oregano natural extracts in precooked beef burger by assessing the lipid oxidation extent and sensory analysis. Five formulations (F) of hamburger were prepared from beef and mechanically separated as follows: meat containing sodium erythorbate (F1); deodorized rosemary extract (F2); oregano extract (F3); rosemary plus oregano extracts (F4) and without antioxidant addition, denominated control formulation (CF). The samples were frozen at −18˚C for 24 hours, then submitted to heat treatment in an electric oven with internal controlled temperature of 75˚C, and again frozen for a period of 30 days. The lipid oxidation extent (determined by thiobarbituric acid reactive substances-TBRS) was evaluated at 0, 15 during 30 days. After heating in plate to temperature of 75˚C, the samples were submitted to color, taste and odor evaluation by 40 untrained tasters. The formulations F1, F2 and F4 presented lower concentrations of TBRS, whereas CF at day zero already showed very high values, indicating oxidation of the product. The samples showed good acceptance in the sensorial analysis.

Accelerated stability tests are indicated to assess, within a short time, the degree of chemical degradation that may affect an active substance, either alone or in a formula, under normal storage conditions. This method is based on increased stress conditions to accelerate the rate of chemical degradation. Based on the equation of the straight line obtained as a function of the reaction order (at 50 and 70 o C) and using Arrhenius equation, the speed of the reaction was calculated for the temperature of 20 o C (normal storage conditions). This model of accelerated stability test makes it possible to predict the chemical stability of any active substance at any given moment, as long as the method to quantify the chemical substance is available. As an example of the applicability of Arrhenius equation in accelerated stability tests, a 2.5% sodium hypochlorite solution was analyzed due to its chemical instability. Iodometric titration was used to quantify free residual chlorine in the solutions. Based on data obtained keeping this solution at 50 and 70 o C, using Arrhenius equation and considering 2.0% of free residual chlorine as the minimum acceptable threshold, the shelf-life was equal to 166 days at 20 o C. This model, however, makes it possible to calculate shelf-life at any other given temperature.

The proportion of GPP was similar in all the groups, allowing us to conclude that ideal GPP proportion, based on the entire group mean, was 23.8% of Rifocort® ; 7.0% of camphorated PMCC; and 69.2% of iodoform.

Cassava flours are obtained from the roots of Manihot esculenta Crantz and daily fairly consumed by the Brazilian population considering it comes to hum food, and also inserted into food baskets, besides to present low cost and easy access, in addition to being plant easily cultivated by the population. However, the food obtained with cassava may contain hydrocyanic acid, in the form of cyanogenic glycoside when those meals are not cooked properly. The oral toxicity can range 30 -210 mg/kg body, the average daily consumption per capita in larger rural areas than in urban areas for cassava flour 19.1 g against 4.7 g, respectively. Brazil's North and Northeast have higher consumption of cassava flour, associated with family monthly monetary income, making this region more vulnerable to poisoning. The objective of this study was to quantify cyanogenic glycosides present in some types of Brazilian cassava foods by means of spectrophotometric technique (reading at a wavelength of 530 nm). For quantitative determination of cyanide content, linamarase hydrolysis was used. The amount of cyanide was determined, and results were: artisan toasted cassava flour: 15 mg/500g, sweet cassava starch: 32.5 mg/500g, artisan dried cassava flour: 37.5 mg/500g, "bijuzada" cassava flour: 60 mg/500g, industrialized, toasted cassava flour: 115 mg/500g, industrialized, raw cassava flour: 140 mg/500g, and wet cassava flour: 225 mg/500g. Considering the chronic ingestion of cyanide present in these foods, they can cause public health problems.

A Terapia Assistida por Animais (TAA) é um recurso terapêutico que utiliza a relação humano-animal na promoção da saúde física, social e emocional, bem como para melhorar as funções cognitivas das pessoas. Uma revisão da literatura foi realizada sobre resultados da Terapia Assistida por Animais em diferentes enfermidades. Foi realizada revisão do tipo narrativa sobre Terapia Assistida por Animais em bases científicas de dados como: Scientific Electronic Library (SciELO), US National Library of Medicine – National Institutes of Healh (Pubmed), Scifinder (MedLine), sites institucionais nacionais e internacionais de interesse. A Terapia Assistida por Animais ou Atividade Assistida por Animais (AAA) é utilizada como intervenção em diferentes níveis de cuidados e de pessoas. Dentre os principais benefícios, podem ser citados: diminuição da frequência cardíaca e pressão arterial; melhora do humor do paciente e da própria equipe de profissionais; favorecimento da humanização no ambiente hospitalar; diminuição da percepção da dor; queda nos níveis de colesterol; promoção de bem-estar; melhora nas relações interpessoais; redução de depressão e demência; melhora na linguagem verbal e na condição motora. Assim, com base nas experiências, pode ser sugerida a inclusão desta prática no Sistema Único de Saúde por meio da Politica de Práticas Integrativas e Complementares.

Both, Unified Health System (SUS) and the National Health Service (NHS) offer free access to the population. However, regarding the development of primary health care, differences can be noted in the coverage of these two public health systems. Therefore, the objective is to carry out a critical comparative analysis of these two services. A literature review was conducted on scientific electronic databases and web pages of the Ministry of Health and United Kingdom Department of Health. The results showed although SUS and NHS are based on the same principles, they had to make different decisions over the years to adapt to the socioeconomic, epidemiological and historical several contexts. In SUS context, regarding the management and financing of the system, occurred a progressive increase in the participation of municipalities and states while the federal public budget decreased. The NHS funding, instead, remained from national taxes, and the regional offices are responsible for the execution and contracting of the health services.Keywords: Unified Health System; health services accessibility; public health. RESUMOO Sistema Único de Saúde (SUS) e o National Health Service (NHS) possuem caráter público e oferecem acesso gratuito aos serviços de saúde. No entanto, em relação ao desenvolvimento da atenção básica, existem diferenças na cobertura destes dois sistemas. O objetivo foi fazer uma análise comparativa crítica entre os dois sistemas. A revisão bibliográfica do tipo narrativa foi conduzida em bases eletrônicas científicas de dados e portais do Ministério da Saúde e United Kingdom Department of Health. Apesar de serem guiados pelos mesmos princípios, o SUS e o NHS assumiram decisões diferentes ao longo dos anos a fim de se adaptarem às realidades socioeconômicas, epidemioló-gicas e contextos históricos que presenciaram. No SUS, foi observado um aumento progressivo da participação dos Municípios e Estados na gestão e financiamento do sistema e uma diminuição dos gastos públicos federais. No NHS, o financiamento se manteve concentrado na coleta de impostos da esfera nacional, estando as estâncias regionais responsáveis pela execução e contratação dos serviços de saúde.Palavras-chave: Sistema Único de Saúde; acesso aos serviços de saúde; saúde pública.
