ABSTRACT
Soymilk was produced from vegetable soybean and fermented by probiotics (Lactobacillus acidophilus La-5, Bifidobacterium animalis Bb-12) in co-culture with Streptococcus thermophilus. The composition of the fermented beverage and oligosaccharides content were determined. The effect of fructooligosaccharides and inulin on the fermentation time and viability of probiotic microorganisms throughout 28 days of storage at 5 °C were evaluated. The soymilk from vegetable soybeans was fermented in just 3.2 h, when pH reached 4.8. Fermentation reduced the contents of stachyose and raffinose in soymilk. Prebiotics had no effect on acidification rate and on viability of B. animalis and S. thermophilus in the fermented beverage. The viable counts of B. animalis Bb-12 remained above 108 CFU mL-1 in the fermented soymilk during 28 days of storage at 5 °C while L. acidophilus La-5 was decreased by 1 log CFU mL-1. The fermented soymilk from vegetable soybeans showed to be a good food matrix to deliver probiotic bacteria, as well as a soy product with a lower content of non-digestible oligosaccharides.(AU)

ABSTRACT
This study evaluated the effects of incorporating the probiotics Bifidobacterium animalis subsp. lactis Bb-12 (B. lactis) or Lactobacillus acidophilus La-05 (L. acidophilus) into goat ricotta on the technological, physicochemical, physical and sensory parameters of this product during refrigerated storage, as well as the protective effects of the goat ricotta on the survival of the tested probiotics during exposure to simulated gastrointestinal conditions. Incorporating the tested probiotics did not affect the yield or syneresis of the obtained goat ricotta. The counts of L. acidophilus and B. lactis during the chosen storage period were approximately 6 log CFU/g. The ricotta samples containing a probiotic strain presented smaller and greater amounts of lactose and lactic acid, respectively, and exhibited greater hardness and lower brightness after storage compared with the samples lacking a probiotic. No differences were observed in the fatty acid profiles of the goat ricotta containing or not containing a probiotic. All of the ricotta samples were described as a soft cheese with a homogeneous texture; however, the goat ricotta cheeses containing L. acidophilus or B. lactis were described as having a more acidic flavor. At the end of a challenge using experimental human digestive conditions, the counts of each of the tested probiotic strains were approximately 6 log CFU/g if it had been incorporated into goat ricotta. These results demonstrated the feasibility of incorporating L. acidophilus or B. lactis into goat ricotta because these probiotics did not negatively affect the quality characteristics of this product and suggested that goat ricotta is an efficacious food matrix for maintaining the viability of these probiotics during storage and under the stressful conditions imposed by the human gastrointestinal tract.
ABSTRACT
Nessa pesquisa objetivou-se avaliar o efeito da adição de leite bovino na fabricação de queijo coalho de leite de cabra nas características físico-químicas e sensoriais a fim de corroborar com a melhora da qualidade e aceitação do produto. Os queijos foram preparados com cinco proporções de mistura de leite caprino:bovino: Q1 (4:0); Q2 (3:1); Q3 (1:1); Q4 (1:3); Q5 (0:4), nas quais se utilizou um modelo estatístico inteiramente casualizado constando de cinco tratamentos e três repetições. As amostras foram submetidas às análises: microbiológicas, como controle de qualidade; físico-químicas: colorimétrica, derretimento, rendimento, umidade, gordura, proteína, extrato seco total, pH, atividade de água (Aw) e sensorial: teste de aceitabilidade e ordenação da preferência. Os valores médios mostraram-se significativos (p<0,05) para as análises de umidade, Extrato Seco Total (EST), proteína, cinzas, acidez e parâmetro colorimétrico b*. A avaliação global e a preferência dos consumidores, na análise sensorial, diferiram significativamente para o queijo elaborado com 100% de leite de cabra. A elaboração de queijos coalho a partir de misturas desses leites apresenta-se viável, tanto do ponto vista nutricional, quanto sensorial, representando uma potencial alternativa para a agroindústria de produtos lácteos.

A cicatriz de cesariana como causa de morbidades ginecológicas, algo até pouco tempo ignorado pelos ginecologistas, é atualmente foco de importante discussão. O aumento atual da via abdominal para o parto faz desse tópico um assunto de extrema importância no cotidiano médico. O sangramento pós-menstrual sem causa aparente tem, na maioria das vezes, a cicatriz de cesariana como fator causal. Pode ocorrer, também, o comprometimento da fertilidade ou pela dificuldade de implantação embrionária ou pela piora da qualidade do muco cervical, em razão do sangramento uterino anormal. Discute-se, hoje em dia, qual o melhor método para o diagnóstico das alterações uterinas decorrentes da cicatriz de cesárea. A investigação pode ser feita inicialmente pela utrassonografia transvaginal, mas a histeroscopia tem maior acurácia além de permitir o tratamento específico. Em todas as situações, a investigação e o bom planejamento terapêutico só podem ser feitos quando o ginecologista conhece bem essa afecção.
The cesarean scar as cause of gynecological morbity, fact that used to be ignored by gynecologists, is the subject of an important discussion nowadays. The current increase in the number of abdominal delivery makes this subject a constant in our daily pratice. The post-menstrual uterine bleeding without an apparent cause has, in the majority of cases, the cesarean scar as only predisponent factor. There might also be infertility due to the difficulty of embryonic implantation or to the presence of the blood making the cervical mucus hostile. Currently, there is a discussion on the best method for the diagnosis of uterine alterations due to cesarean scar. The investigation may be initially accomplished by means of transvaginal ultrasound, but only the hysteroscopy may be precise in the diagnosis and allow specific treatment. In all situations, the investigation and adequate therapeutic planning can only be made if the gynecologist has ample knowledge on this pathology.

OBJETIVO: avaliar os resultados dos 14 primeiros casos de tratamento cirúrgico videolaparoscópico de pacientes com endometriose profunda do septo retovaginal no Setor de Endoscopia Ginecológica do Hospital do Servidor Público Estadual Francisco Morato de Oliveira. MÉTODOS: foi realizada análise retrospectiva com dados retirados de prontuários, associada ao atendimento ambulatorial pós-operatório das 14 pacientes operadas entre fevereiro de 2002 e fevereiro de 2004, apresentando as seguintes características: a idade das pacientes variou de 33 a 44 anos, com média de 38,4; a paridade variou de 0 a 3, com média de 1,1; os principais sintomas pré-operatórios foram: dismenorréia em 14 (100 por cento), dispareunia de profundidade em 12 (85,7 por cento), dor pélvica acíclica em 10 (71,4 por cento), dor à evacuação em duas (14,3 por cento), enterorragia em duas (14,3 por cento) e infertilidade em duas (14,3 por cento). A dosagem plasmática do CA-125 esteve entre 3,6 e 100,3 U/mL, com média de 52,9 U/mL. RESULTADOS: o exame anatomopatológico das lesões do septo retovaginal foi compatível com endometriose em nove (64,3 por cento) pacientes. Quanto à sintomatologia dolorosa, houve regressão total em sete (50 por cento) pacientes, melhora de mais de 80 por cento em duas (14,3 por cento), sem melhora em quatro (28,6 por cento) e piora em uma (7,1 por cento). A incidência de complicações foi de 14,3 por cento, sendo uma lesão de ureter associada a lesão no sigmóide e uma lesão retal diagnosticada no 8º dia de pós-operatório. CONCLUSAO: pode-se concluir que a endometriose profunda do septo retovaginal pode ser tratada pela cirurgia laparoscópica, com baixa morbidade, e trazendo alívio dos sintomas para a maioria das pacientes.
