ABSTRACT
High-fat diets affect male reproduction and sexual function. Therefore, we evaluated the effects of prolonged resveratrol administration on the metabolic, sperm, and testicular parameters of rats fed a cafeteria diet. Male Wistar rats were divided at weaning into control (C, n = 20) and cafeteria (CAF, n = 16) groups. At 3 months, half of them were given daily supplementations of resveratrol (C-R, n = 10; CAF-R, n = 8) at a dosage of 30 mg kg-1 body mass for 2 months. Animals were killed at 5 months of age, and blood, spermatozoa, and testes were collected for further analysis. Data were analyzed by one-way ANOVA, and P < 0.05 was considered statistically significant. The CAF diet promoted hyperglycemia (P < 0.0001), and treatment with resveratrol reversed this condition (P < 0.0001). The CAF diet reduced sperm viability and motility, while resveratrol improved these parameters (P < 0.05). Regarding testicular morphology, the height of the seminiferous epithelium was reduced in the CAF group compared with that of the C group (P = 0.0007). Spermatogenic cell proliferation was also reduced in the CAF group compared with that of the C group. However, the CAF-R showed an increase in cell proliferation rate compared with that of the untreated CAF group (P = 0.0024). Although it did not modify body mass, the consumption of a CAF diet promoted hyperglycemia, adverse testicular morphology remodeling, and abnormal sperm, which were attenuated by treatment with resveratrol, thus suggesting a protective effect of this antioxidant on spermatogenesis.

Após a observaçäo da realidade na Unidade Básica de Saúde Parque das Indústrias do Município de Londrina, os autores verificaram, em vários levantamentos realizados, a deficiência no controle e distribuiçäo de medicamentos, bem como a falta dos mesmos para usuários desta Unidade. Portanto, objetivou-se analisar a sistemática de distribuiçäo e prescriçäo de medicamentos desses serviços nas Unidades Básicas de Saúde da Regiäo Sul, além de propor um esquema de controle para tal distribuiçäo. Para atingir tal objetivo, foram levantados dados através da aplicaçäo de questionários para 17 médicos e dentistas, 25 auxiliares de enfermagem, além de 51 pacientes que foram submetidos a consultas médicas ou odontológicas nas citadasUnidades Básicas de Saúde (UBS). Com a mesma finalidade, também foram realizadas entrevistas com a chefia da divisäo de unidades ambulatoriais da Secretaria Municipal de Saúde e Centrofarma do Serviço de Saúde do Município
