Experiências de famílias na imunização de crianças brasileiras menores de dois anos

O objetivo foi descrever as experiências de famílias sobre imunização de crianças menores de dois anos. É estudo de natureza descritiva, com análise qualitativa dos dados, entrevistas não estruturadas com 22 sujeitos. Os resultados foram agrupados em: conhecimentos práticos sobre imunização, responsabilidade e obrigatoriedade na imunização e ampliação da prática de imunização. Foram destacados elementos que fortalecem a imunização: experiência e realização pessoal no papel de ser mãe, temor de adoecimento, reconhecimento como um bom cuidado, acesso, flexibilidade do horário, divulgação, cartão de vacinas, campanhas de vacinação e disponibilidade de vacinas, e elementos da não imunização: inexperiência dos pais, recusa de aplicações simultâneas de vacinas, assistência fragmentada, ausência de diálogo, discriminação, falsas contraindicações e obrigatoriedade. A imunização centrada no cumprimento do calendário vacinal, ou em situações autoritárias, está descolada do cuidado familiar. O vínculo com as famílias precisa ser fortalecido para ampliação da adesão às medidas de proteção e promoção da saúde da criança.

Population parameters in Brazilian Thoroughbred

The information in this study has been provided by the Brazilian Association of Racehorse Breeders [Associação do Brasileira dos Criadores do Cavalo de Corrida (ABCCC)]. It can be found in the files on the CD-ROM developed by the ABCCC in 1999. A total of 5008 finishing time records related to 2545 winning horses that ran in the classical calendar on Brazilian hippodromes during 25 years (197498) were analysed. There were a total of 9949 horses on the relationship matrix. The variance components were estimated using the multiple-trait derivate-free restricted maximum likelihood (MTDFREML) program, for an animal model. Generation intervals were higher in the maternal side (10.91 years) than in the paternal one (10.41 years). The estimates for genetic permanent environmental and phenotypic variances and heritability were 0.291, 0.161, 3.486 and 0.08, respectively. The phenotypic standard deviation for time in races was 1.86729 s. Genetic time trend on Thoroughbred races in Brazil was small and could be accelerated if selection considered the trait time effectively. With respect to the animal's country of birth, the results show that there has been an intense participation of foreign animals in breeding Brazilian Thoroughbreds.

Assessing the effects of vector control on dengue transmission

The dengue virus is an arbovirus transmitted to humans through mosquito Aedes aegypti. To describe the dynamics of dengue disease within these two populations we develop a compartment model taking into account chemical controls and mechanical control applied on the mosquitoes, which are the currently available controlling mechanisms to prevent dengue disease. To mimic seasonal variations, some parameters of the model are allowed to depend on time in order to divide a calendar year in favorable and unfavorable periods regarded to the development of vector population.

Gastroprotective and antisecretory effects of Ailanthus excelsa (Roxb)

Ailanthus excelsa (Roxb), an Egyptian medicinal species highly important for treating numerous diseases, was investigated against experimentally induced gastric ulcer in rodents. We evaluated the gastroprotective effect of four extracts (petroleum ether, diethyl ether, chloroform, and methanol) of A. excelsa bark by using the ethanol-induced gastric lesion model. The pretreatment of animals with methanolic, petroleum ether, and chloroformic extracts (100 mg/kg, oral (p.o.)) from A. excelsa significantly reduced gastric lesion induced by ulcerogenic agent (56, 47, and 70%, respectively) when compared with animals pretreated with vehicle. However, the diethyl ether pretreatment led to the least gastric lesion damage (83%), similar to the standard antiulcer drug, cimetidine, at the same dose (100 mg/kg, p.o.). The lower effective dose of diethyl ether extract, as well as cimetidine, given by intraduodenal route, significantly increased the pH values and reduced the acid output of gastric juice. Sterols, triterpenes, and quassinoids are present in the diethyl ether extract of A. excelsa stem bark, which presented the best gastroprotective action among the studied extracts. Our study confirmed the traditional indications of A. excelsa for the treatment of gastric ulcer.
