The results of the epidemiological, clinical and laboratory investigations, carried out in the 1994-1997 interval in the Iaşi district, on various populational groups, to indicate the prevalence of the antibodies anti-HVC possessors are presented. In 3611 patients with clinical-epidemiological HCV diagnosis, it was recorded a prevalence of the anti-HCV antibodies (AcHCV) presence of 22.7%. Posttransfusional hepatitis, epidemiologically diagnosed in 205 hospitalised patients was attributed to HCV in 11.6% of the cases, and in 94 patients with neurological diseases, AcHCV were identified in 9.6%. The presence of AcHCV at 825 persons in medico-sanitary staff, from risk domains, has recorded a prevalence of 8.0%. In the January 1997-September 1997 interval, the investigation by IIIrd generation ELISA of 51,149 blood samples of donors from various areas indicated the presence of AcHCV with an interval average of 2.6%.

[Epidemiological considerations of the arbo- and arenaviruses].

The complex epidemiological process of arboviral and arenaviral diseases, their dependence on a multitudine of etiologic agents, the risk of severe manifestations, absence of a specific treatment and difficulties in preparing the vaccines, place these diseases among those of high concern at national and international level. The multidisciplinary investigations carried out in Moldavia by M. Duca, Eugenia Duca, Gr. Teodorovici, Alla Vâţă, St. Dumitriu, V. Luca, D. Buiuc, A. Ivan and others have elucidated numerous aspects regarding the epidemiology and prevention of arboviral diseases. The increased morbidity by meningitis and meningoencephalitis recorded in Romania the interval summer--early fall 1996 was attributed based on serologic diagnosis, to West Nile virus. The etiological investigations were done both in our country (Cantacuzino Institute, Institute of Virology, Laboratory of the Ministry of National Defence) and abroad (Pasteur Institute at Paris, Colindale Institute London, CDC, Atlanta, USA). For the Romanian population the risk for a periodical re-emergence of some arbovirus diseases is due to favorable local conditions with the relationships with geographical areas were these diseases have and endemic-epidemic evolution are added.

[The importance of the use of selenium in the role of an antioxidant in preventing cardiovascular diseases].

The evaluation of the results of the oxygen free radicals (RLO2) formation is a current subject in biology and medicine. The oxidative stress, which is the altering of the balance between the higher activity of oxygen and the enzymatic or nonenzymatic protection systems, may be one of the causes that starts and aggravates a disease. In this context, the supplementation of the diet with selenium, superoxide dismutase, vitamins A, C, E, is considered a primary prevention measure (for the apparently healthy persons) and a secondary one (for those with advancing forms of disease) that is both efficient and modern by utilization of some "drug-food" products. The transversal study realized on a group of 39 blood donors presence of the cardiovascular risk determined by the raising of the prevalence of some atherogenic factors (active smoking, hypercholesterolemia) which is also expressed by the lowering of the level of some oxidative stress indicators (glutathione peroxidase--GSH-Px < 0.139 moli/ml and catalase < 2.20 U/ml). The simultaneous low intake of selenium from the central drinking water supplies in the city of Iaşi (0.1-1 g/l) has permitted us to consider necessary the diet supplementation both with foods rich in vitamins with an antioxidant role and with specific medication with selenium, as a protective micro-element.

[The concordance and discordance of cardiovascular risk factors in a group of twin children].

The cross-sectional study of epidemiological screening type has permitted to evaluate some cardiovascular risk factors in two groups of monozygotic (MZ) and dizygotic (DZ) twins born between 1975-1990, in the town of Iaşi. In the 89 MZ pairs and 112 DZ pairs, certain constitutional and behavioural cardiovascular risk factors have presented values of prevalence with statistical signification (p < 0.05) in terms of their age, sex, the urbanisation time and the educational level of their parents. In risk factors existence or absence to both of the twins have put into evidence, to the MZ, most enhanced values of concordance as regards: overweight (66.6%), excessive consumption of salt (56.9%), food with atherogenic risk (50.9%). The concordance values have been less in DZ compared to MZ concerning all the risk factors excepting compartmental type A (77.7%). By analysing the concordance variants, an preponderant influence of the environment has been noted in the studied MZ and heredity and environment influence in DZ. By measuring the arterial blood pressure values at the twins and the twins parents, a prevalence of the essential arterial hypertension is noticed to both of the twins, 6.2% in MZ pairs and 6.9% in DZ ones.

[Epidemiological observations on the physical activities of patients with arterial hypertension].

The authors point out the results of some multidisciplinary epidemiological researches concerning the relation between the multifactorial etiology of arterial hypertension (AHT) in employers working in two factories and the nature of physical activity. The results show that the highest percentage of AHT cases is in the persons which do not have physical activity (occupational, housing or leisure). The women with AHT, which are frequently supra-ponderously, make a low level of physical activity. They have effort respiratory modifications in 40% of cases. The decreasing interest for control and prevention of health risks of the level of occupational health services has medical and social negative effects on long term.

[Occupational stress--risk factor in essential arterial hypertension].

The stress was recorded taking into consideration the epidemiological interview, using a standard methodology by filling in the type card the occupational stress (OS) and the family stress (FS). The constitutional factors (behaviour type A, body weight index > 25 Kg/m2) as well as the consumption in excess of salt, have significantly correlated themselves, both in individuals with OS and FS, and in those with the exclusively OS. The modification of biochemical constants (total cholesterol, triglycerides, total lipids, HDL-cholesterol, LDL-cholesterol) significantly associate themselves in persons to which the presence of OS and FS, of the occupational one, respectively was put into evidence (chi 2 = 94.10 for 5 freedom degrees and p < 0.001, chi 2 = 118.94 and p < 0.001, respectively). The prevalence of persons with pathologic values of total lipids was 58.7%, of triglycerides 35.7%, of total cholesterol 12.7%, of LDL cholesterol 27%, and of HDL-cholesterol 44.4%. Measuring the values of systolic and diastolic arterial hypertension an increase above the normal values of limit systolic arterial hypertension at 23.8% and at 12.3% for illness systolic arterial hypertension was found. The evaluation of association of certain cardiovascular risking factors in individuals with occupational stress has permitted a global understanding, useful for the elaboration of some preventive programmes.

[Emergence of transmissible disorders, a continuous process--a new type of viral meningoencephalitis].

In the interval 1994-1999, in Australia, Malaysia and Singapore, epizootic and epidemiological episodes of meningoencephalitis and severe acute respiratory syndromes were reported. Highly lethal in horses, swine and humans, the episodes were proved to be caused by the "new" viruses Hendra (HeV) and Nipah (NiV). At the same time three "new" viral agents have been isolated: Lyssavirus, Menanglevirus and Tupaia paramyxovirus. The intense contemporary circulation of people, animals and food products together with changes in human ecosystem favor new relations between humans and the "natural reservoirs" of biologic agents with a pathogenic potential for domestic and peridomestic animals and humans.
