[Location of single skin lesions of paucibacillary leprosy].

In this paper the authors study the sites of single lesions in 317 paucibacillary patients registered at the outpatient units of the CMS Jorge Saldanha and the Curupaiti State Hospital in Rio de Janeiro, Brazil. The preferential sites of lesions in the population studied, their relation with age and sex and factors likely to influence their distribution are discussed. The findings are compared with other similar studies performed in Asia and Africa.

Effect of calcitonin on hepatic drug metabolism.

A single dose of calcitonin (150 mIU/100 g body weight, sc) produced a significant decrease in liver antipyrine hydroxylase and aminopyrine demethylase activities. By contrast, pentobarbital sleeping time was not altered by calcitonin treatment. The present results indicate that acute calcitonin administration depresses the metabolism of substrates of the mixed function oxidase system of rat liver.

[Cross-sectional study of intestinal parasites and Chagas' disease in the Municipality of Novo Airão, State of Amazonas, Brazil].

A cross-sectional study was performed on the residents of one in every ten households in the town of Novo Airão, in the northern meso-region of the State of Amazonas, 250 kilometers from Manaus by riverboat. A family cluster sample of 89 dwellings was studied. A stool sample was requested from each of the inhabitants for examination using the Lutz sedimentation and Baermann-Moraes-Coutinho techniques, and blood was taken by venous puncture for Trypanosoma cruzi Elisa antibody testing and immunofluorescence. From a total of 316 stool samples, 87.6% had one or more parasites: Ascaris lumbricoides (35.1%), Entamoeba histolytica (29.1%), Giardia lamblia (17.4%), and other parasites with lower prevalence rates. These results were directly correlated with lack of sanitation and clean water supply. Of the 346 sera examined, 16 (4.6%) were reactive to T. cruzi antibodies, but only three showed a correlation between this result and human contact with wild triatomines, known locally as "piassava lice".
