Smoking and blood oxygen tension in healthy middle-aged males.

The blood oxygen tension (PaO2) was measured using a Clark-type microelectrode on 'arterialised' capillary blood samples obtained from 74 sitting subjects; these were asymptomatic and spirographically normal men aged 42-63 (average 53.7) years. The mean PaO2 of smokers (83.8+/-6.0 mm Hg) was slightly, non-significantly lower as compared to non-smokers (85.5+/-4.9 mm Hg). The trend towards lower mean values with increase in current cigarette consumption or amount smoked in life did not result in significant differences between smoker sub-groups. The lower normal limit for the whole group was 73.3 and the average PaO2 85.3 mm Hg. Though no significant influence of tobacco use could be demonstrated, the histogram of specific subjects shows a bi-modal distribution in smokers, suggesting the existence of a sub-group (about one third of the smokers) who tend to have lower PaO2s, possibly as a consequence of sub-clinical 'small airway disease'.

Smoking habits in Romania.

The main aspects and consequences of tobacco use resulting from a series of field surveys in Romania are reviewed. The proportion of smokers in middle-aged adults is about 10 per cent for women and 40 to 50 per cent for men. Cigarettes are practically the only form of tobacco consumed--cigars are very rarely smoked and pipe-smoking accounts for less than 1 per cent of tobacco use. Less than 10 per cent of smokers use more than 25 cigarettes a day. Age at starting to smoke is low, with a quarter of smokers taking up the habit by the age of 15. Ninety per cent of the smokers admit to inhaling, and about half the men and nearly all the women smoke filter cigarettes.

Coronary heart disease and risk factors in some special type collectivities.

Transversal epidemiologic investigations carried out in different populations from several regions of Romania : Gurghiu Valley (lumberjacks from a mountain region), Danube Delta and Razelm lagoon complex (fishermen), and Bucharest have shown that, in spite of the high caloric value of food and even of a high intake of saturated fats, mean serum cholesterol is lower in the rural areas than in Bucharest, probably owing to the strenuous physical work. However, except myocardial infarction, more frequent in the urban than in the rural regions, the other forms of coronary heart disease have a relatively higher frequency in villages, particularly atrial fibrillation and ECG signs of ischemia. These findings might be explained by a greater prevalence of hypertension in these populations. It is concluded that the risk factors, which act synergically, depend on the complex structure of the "ecologic niche".
