1. The in vivo S-oxidation of albendazole was measured from the pharmacokinetic profile of albendazole sulphoxide and sulphone determined in young male sheep receiving oral albendazole (1.9 mg/kg). Studies were carried out before, and each month after, oral infestation by 150 metacercariae of Fasciola hepatica. 2. Parasitic pathology was ascertained by clinical observation of animals, and the increase in plasma antibodies directed against liver flukes. 3. Rate of conversion of sulphoxide to sulphone and rate of sulphone elimination, were respectively decreased by 47% and 87% at week 8 post-infection, whereas significant increases in the area under plasma sulphone concentrations versus time curve and mean residence time, occurred 4-12 weeks following the infestation. 4. A 58% decrease in albendazole sulphonation was demonstrated in liver microsomal preparations obtained from 8-week-infected sheep, while there was no change in the FAD-directed sulphoxidation of albendazole. 5. The transient impairment of albendazole sulphonation could be related to the decrease in liver microsomal cytochrome P450-dependent monooxygenases observed in sheep with a similar parasitic pathology.

An epidemiological analysis of the forms and distribution of Dengue fever in Brazil and worldwide was carried out. The National Program of Dengue Control (NPDC) was evaluated based on the data available at 'Diagdengue' an official computerized information system allowing to follow-up the implantation and impact of the Program. A factorial analysis was performed by means of a set of indicators contributing to variability. The indicator scores were added and the cities demanding for prior attention of the NPCD were classified for the construction of an index, which is presented three-monthly for every state, with intervals distributed between 0 and 9. The implantation of the NCPD is irregular. Cities with bad implantation are predominating in the north and northeast of the country. In the second analysis, socio-economic variables of the selected cities were added. For the association tests these cities were classified into two groups: 'Bad' and 'Good/Very Good', based on the association of the index of building infestation informed in the FAD (Yellow Fever and Dengue) database and the constructed index. Associations were verified based on variance analysis, trend test and trend estimate. It was observed that cities with low rates of illiteracy, efficient garbage collection and high ratio of sanitary installations are correlated with a good classification of the city according to Diagdengue.
