[Comparative study of maximal midexpiratory flow rate in normal smoking and non-smoking subjects].

MMF is considered one of the most sensitive parameter to point out initial decay of small airways that should appear prematurely in smokers as compared with non smokers. To verify the above we tested male subjects apparently free from any respiratory disease. They were classed into two groups of equal number: the first group of smokers, the second one of non smokers. We did not find any statistically significant difference between the two groups: this is probably due to the young age of the subjects and consequently to the relative short period of exposure to tobacco smoke.

[Alveolaro-capillary gas exchange. Considerations on the evaluation of carbon monoxide diffusion].

This study is based on 107 male individuals aged between 20 and 73 years, all of them exempt from any disease. They were submitted to instrument examination for measuring the CO pulmonary diffusing capacity with the single breath method. The data so obtained were then statistically elaborated considering the index value of CO transfer, the Helium partition (RHe) and the CO partition and diffusion (R&DCO). The CO transfer index has shown a particularly extensive range; if we take as normality level-20%, a consistent ratio of individuals (20,56%) falls in a range of deficitary pulmonary diffusion though in absence of aèny clinical evidence of pathology. The subsequent statistical elaboration of the data after logarithmic transformation, by the means of the linear regression model, has allowed to reduce the variance of the R&D CO index improving his classificative capability.

[Carbon monoxide alveolar-capillary diffusion: considerations on inter-personal variability].

Twenty three male subjects 21 to 53 aged were undergone to lung diffusion test using breath holding method. Each subject was tested three times in different days. The results were evaluated by Bartlett's Chi-square test and by Kendall's coefficient of concordance. Correlation between the CO distribution and diffusion index (R&DCO), the Helium distribution index (RHe), the time of breath holding and the volume of "single breath" was found. It seems it will be possible to improve the inter-personal estimation to 1.25% about.

[The influence of helium concentration in determining respiratory function parameters].

Before a research about normals values of lung diffusing capacity for CO in Italian people, the Authors investigate if different concentration of Helium in respiratory gases could have any influence on data. Experiments were performed by testing 8 male subjects. Each one repeated lung function tests three times using gas mixtures with different Helium percentage. Results were evaluated by meaning of t Studnt's and Bartlett's Chi-square tests. Results show no significant difference.

[Biomechanical risk for the upper limbs: experience at a factory of feeding electric cables].

Cumulative trauma disorders are found more and more frequently in working environments. Our examination concerns a factory of feeding electric cables, whose workers were subjected to a sanitary checking in 2001, 2002, 2003. The valuation of the risk due to a biomechanical overload of the upper limbs, carried out according to the OCRA method, pointed out, with reference to the specific task of pressing, a middle-high grade of exposure, while the clinical-instrumental results showed symptoms and objective signs of suffering on the median nerve of the wrist with regard to a significant percentage of workers. The following interventions on the production cycle and on the exposure times obtained a reduction of the risk with a subsequent decrease of the noticed troubles.
