Colon Cancer and Swimming Exercise: Effect on Wistar Rat Testes

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)This study was undertaken to determine whether colon cancer (CC) and chronic swimming exercise alter rat testis. Eleven weeks old rats were distributed into control group (n=6) and the groups that were induced to develop CC by dimethylhydrazine injections (nEG, EG0, EG2 and EG4; n=10 each group). In the group nEG, the rats did not swim, whereas groups EGO, EG2 and EG4, underwent a swimming program with distinct loads (0, 2 and 4% of body mass, respectively) for 35 weeks. The morphometry, stereology and cell counts showed damage caused by the CC on the germ epithelium. These results were noteworthy since this was the first report to associate the CC with testicular damage. Swimming exercise had no significant role in reducing, or increasing the CC effects on the testis, despite having slightly improved the testis structure of the exercised rats without load. In conclusion, CC caused testis impairment, which could not be avoided by the swimming exercise.564557566Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

Histomorphometric evaluation of the neotropical brown brocket deer Mazama gouazoubira testis, with an emphasis on cell population indexes of spermatogenic yield

Information on the reproductive biology of neotropical cervids is scarce. Therefore, the aim of this study was to perform biometric, histologic and stereologic analyses of the brown brocket deer Mazama gouazoubira testis, with an emphasis on the intrinsic yield and the Sertoli cell index. Seven adult males kept in captivity were used. The animals were immobilized; anesthetized and testicle fragments were obtained by biopsy incision. The material was fixed, processed and examined by routine histological methods for light microscopy. The average body weight was 17.2 kg, from which 0.40% were allocated in gonads and 0.33% in seminiferous tubules, which represented 85.9% of the testis parenchyma. The mean albuginea width and volume were 345.7 mu m and 3.5 mL (5.3% of the testicular weight), respectively. The mean mediastinum volume of both testicles was 1.0 mL (1.5% of the testicular weight) and the testicular parenchyma volume corresponded to 93.1% of total testicular weight (64.9 g). The seminiferous tubules diameter was 224.4 mu m, while the epithelium height was 69.6 mu m. On average, an adult brown brocket deer showed a total of 1418 m of seminiferous tubules in both testicles (21.5 m per gram of testis). Each stage I seminiferous tubular cross section contained 1.10 type A spermatogonia, 13.4 primary spermatocytes in pre-leptotene/leptotene, 13.7 spermatocytes in pachytene, 48.8 round spermatids and 3.7 Sertoli cells. The general yield of spermatogenesis was 44.7 cells and the Sertoli cell index was 13.2. The qualitative and quantitative description of testicular histology of brown brocket deer help to understand its spermatogenic process and to establish parameters for the reproductive biology of this wild species. Furthermore, the data from the present research will help further studies using other species of Brazilian cervids, especially endangered ones, making an additional effort to the species preservation.

Satisfação dos usuários assistidos nos Centros de Especialidades Odontológicas do Município do Recife, Pernambuco, Brasil Patient satisfaction at Specialized Dental Clinics in Recife, Pernambuco State, Brazil

O estudo objetivou avaliar a satisfação dos usuários assistidos nos Centros de Especialidades Odontológicas do Município do Recife, Pernambuco, Brasil. Realizou-se entrevista pessoal padronizada com 272 pacientes utilizando o Questionário de Avaliação da Qualidade dos Serviços de Saúde Bucal (QASSaB). Os resultados indicaram uma avaliação positiva para a maioria das dimensões no geral. A acessibilidade foi um ponto crítico destacado. Houve diferença significante de 5% na satisfação dos usuários, entre as unidades de serviço, para: relações humanas/cirurgião-dentista (p = 0,001); relações humanas/auxiliar (p = 0, 007); eficácia (p = 0,014); acessibilidade/tempo de espera (p = 0,018); ambiente físico/limpeza da recepção (p = 0,004); aceitabilidade (p = 0,029); efetividade/aparência dos dentes (p = 0,029) e efetividade/capacidade de mastigação (p < 0,001). Concluiu-se que a maioria dos usuários está satisfeita com a assistência prestada nos centros e que a satisfação difere em cada centro.<br>This study evaluated patient satisfaction at four specialized dental clinics in Recife, Pernambuco State, Brazil. Data were collected through a standardized self-applied individual questionnaire with 272 patients, to evaluate user satisfaction with public dental services. The findings indicated a positive evaluation on most dimensions, except for accessibility. Significant differences were observed between the services on the following dimensions: patient-dentist relationship (p = 0.001); patient-dental assistant relationship (p = 0.007); effectiveness (p = 0.014) accessibility/waiting time (p = 0.018); physical environment/reception room cleanness (p = 0.004); acceptability (p = 0.029); and effectiveness/tooth appearance (p = 0.029), effectiveness/chewing capacity (p < 0.001). In conclusion, most users were satisfied with the dental care, and satisfaction differed between services
