    ABSTRACT: The aim of this study is to measure the alterations in the trace levels of serum copper (Cu), selenium (Se), and manganese (Mn) in forestry workers testing immunoglobulin G (IgG)-positive for Brucella, Borrelia, and Rickettsia. The study was conducted on a sample of 758 subjects (560 male and 198 female). All the subjects underwent medical examinations, which investigated particularly the presence of clinical signs compatible with zoonoses, and routine blood tests from venous blood sample, which tested previous immunisation versus cited microorganisms and serum concentration of Cu, Se, and Mn. The subjects were divided according to IgG positivity versus the cited microorganisms. The group of subjects with IgG positive versus Brucella showed statistically significant higher Cu levels than controls, while the Mn levels were not; the group of subjects with IgG positive versus Rickettsia showed higher levels of all three tested metals. The concentration of the examined metals did not show statistically significant difference between IgG-positive subjects versus subjects with Borrelia compared to controls. These data could confirm the role of both Cu and Se in the regulation of immune response.

    ABSTRACT: The aim of our study is the comparison between two different biological exposure index, trans-trans-muconic acid (t,t-MA) and S-phenylmercapturic acid (S-PMA), that are minor metabolites of benzene, in the exposure to low concentrations of benzene, to estimate which shows better correlation with the environmental exposure. The study has been conducted upon a sample of 105 male workers in a petrolchemical plant in Sicily. The environmental monitoring data has shown exposure levels within acceptable limits compared with TLV, and these levels have been confirmed by biological monitoring data. The comparison between biomarkers didn't point out particular differences and this data is probably connected to low found levels of exposure.

    ABSTRACT: The objective of the study is evalutation of the risk for ticks strings on foresters. The sample constituted by 325 foresters belong to Messina province as been submitted to medical examination venous tests. Whole sample had to answer to a questionnaire to consider. The prevalence of systemic and skin reactions and we have dose Immunoglobulines versus Brucella Melitensis, Rickettsie Conorii e Borrelia Burgdorferi. The results showed that the 19% has declared past stings of tick, and 4.9% reported symptoms probably deriving to a past infections determined by inquired microorganisms. The serum tests showed that 70% was positive for all microorganisms, instead only 31%. Was never infected by inquired microorganisms. In conclusion our study shows that zoonos is risk linked to stings of tick is relatively high in foresters.

    ABSTRACT: The activity of roadman is not much knowed. The evalutation of the risk evidences the noise and vibrations as the principal polluter. The aim of our study is to go into the knowledge of the working risk of that job. The study was leaded on a sample of 287 roadmen. It was carried out an evalutation of noise exposure of the workers and a biologic evaluation that included: Medical check. Othorhin.laryngoiatric examination. Audiometric examination. Impedenzometric examination. The audiometric exam was conduced in a silent box and with a acoustic rest at least 16 h. The audiometric test were classified in conformity with Merluzzi-Pira-Bosio method. The phonometric evaluations point out, in roadmans examinated, hight exposure to noise with mean Lep d > 90 db. Biological evaluation, through medical check, showed data similar with that of a general group homogeneous for age and sex. Audiometric evaluation showed a noise acoustic trama in 60% of sample. Inpedenzometric exam confirmed the absence of transmissive damage in almost whole sample. In conclusion we can adfirm that noise is a strong factor for roadmen, with evident damage to exposed workers.

    ABSTRACT: The inhalation of glass dusts mixed in resin, generally known as glass fiber-reinforced plastic (GRP), represents a little-studied occupational hazard. The few studies performed have highlighted nonspecific lung disorders in animals and in humans. In the present study we evaluated the alteration of the respiratory system and the pathogenic mechanisms causing the changes in a group of working men employed in different GRP processing operations and exposed to production dusts. The study was conducted on a sample of 29 male subjects whose mean age was 37 years and mean length of service 11 years. All of the subjects were submitted to a clinical check-up, basic tests, and bronchoalveolar lavage (BAL); microscopic studies and biochemical analysis were performed on the BAL fluid. Tests of respiratory function showed a large number of obstructive syndromes; scanning electron microscopy highlighted qualitative and quantitative alterations of the alveolar macrophages; and transmission electron microscopy revealed the presence of electron-dense cytoplasmatic inclusions indicating intense and active phlogosis (external inflammation). Biochemical analyses highlighted an increase in protein content associated with alterations of the lung oxidant/antioxidant homeostasis. Inhalation of GRP, independent of environmental concentration, causes alterations of the cellular and humoral components of pulmonary interstitium; these alterations are identified microscopically as acute alveolitis.
