In this brief review the results of the most important studies about smoking and cardiovascular diseases are referred. Epidemiological, pathological, and clinical data show an higher mortality from coronary heart diseases in smokers, and an higher frequency of atherosclerothic lesions, affecting all types of sistemic vessels. By an analysis of the tobacco smoke composition, some of the effects and acting mechanism of nicotine and Carbone Monoxideon the cardiocirculatory system are treated. It is remarkable that cigarette smoke is only a "risk factor" and overall together other conditions as hypertension or dyslipidamia.

[Possibility of pulmonary circulation study with nongaseous radioactive isotopes].

This paper deales with the applications of radionuclides to the study of human pulmonary circulation for better knowledge of some morphological and dinamic functional aspects. At this time the methods used are divided in three groups in respect to the purpose. - Methods for static investigations of pulmonary perfusion, by scintigraphy with radioalbum aggregates. - Methods for dynamic investigation, general radiocardiography and selective right radiocardiography with radioalbum macroaggregates. - Methods for morpho-functional investigation, especially Isotopoangiocardiopneumography using gamma-camera and Tc99mO4. Here are treated the fields of applications, the purpose and the limits of these methods, used in a large number of and acquired pulmonary vascular diseases.

[Morphofunctional aspects of the pulmonary circulation in kyphoscoliosis; angiocardiopneumographic, scintigraphic and hemodynamic characteristics].

In a group of 30 patients suffering from kypphoscoliosis of different degrew was effected a series of researchs (investigations to value the morphological functional behaviour of the pulmonary circle. The used ways were: angiopneumography, pulmonary perfusional scintigraphy, cardiac catheterisation and radiocardiography. The achieved results allowed to single out interesting aspects both of pulmonary vascular bed compromission and of some haemodynamic parameters. These alterations show different degrees according to seriousness of the deformation and the presence or not of broncopneumonia complications in these patients.

[Characteristics of pulmonary perfusion behavior in bronchial asthma].

Tuelwe patients with asthma were studied by scintigraphic, and isotopoangiocardiographic technics under acute attack. No regionals differences in the pulmonary blood-flow distribution were observed. The results are help ful in the knowledge of ventilation/perfusion relationships and alterations of blood gases produced from asthma attack.

[Lung blood perfusion changes following tubercular processes cured by antibiotic drug therapy].

This is a studym ade by pulmonary perfusional scintigraphy and angiopneumography on 60 patients suffering from tuberculosis of the lung; they were cured by chemoantibiotic treatment. They were recent tubercular diseases with limited extension (nodular infiltrations, former phthisiogenic lobitises, nodular and miliarich disseminations), so their outcomes were extremely modest or not worthy on radiologic plane. The results acquired with these methods firmly showed a larger ematoperfusive injury as to the affected area.
