RESUMO
The clinical, surgical and pathological features of a case of pulmonary sclerosing hemangioma (benign sclerosing pneumocytoma) are presented. We emphasize the fact that the clinical presentation of this rare benign tumor is mostly as a solitary tumor and therefore enters the differential diagnosis of solitary pulmonary nodule.

A introducao da metodologia relativa a area da medicina nuclear propiciou aquisicoes relevantes para o diagnostico e o tratamento de diversas doencas. No campo da obstetricia, a existencia do ovo, desde a primeira semana de desenvolvimento ate o feto maduro, criou novos problemas com relacao aos possiveis efeitos deleterios da exposicao a radiacao. O principal aspecto destes problemas e considerado, com alguma extensao, sob o titulo de protecao radiologica

The immuno-stimulating Levamisole action was checked by the authors in guinea-pigs vaccinated against brucellosis and exposed to the challenge test afterwards against 2.308 Brucella abortus pathogenic strain. Twelve lots of eight guinea-pigs were used disposed in the following distribution: Lots I, III, IV were vaccinated with B-19 strain vaccine; lots II, IV and VI were vaccinated with the same vaccine and, after 48 hours, received the Levamisole injection. Lots VII VIII received only the Levamisole injection and the pathogenic Brucella strain, forming the control groups. The vaccinated guinea-pigs showed a higher protection against challenge, always above 75% in relation to the lots that were only vaccinated, demonstrating a dear immuno-stimulating action of the essayed product. Considering the obtained results in this assay, the authors speculate on the anti-brucellosis vaccines potentialization with immuno-stimulating products, as Levamisole.
