The influence of passive smoking on the cardiovascular system.

Cardiovascular effects of tobacco smoke have been studied in passive smokers far less extensively than in active smokers. Under real-life conditions, passive smokers inhale approximately 0.02 to 0.

[Analytic and diagnostic validity of the determination of carboxyhemoglobin in blood and carbon monoxide in the breath of smokers and non-smokers].

The analytic and diagnostic validity of the determination of carboxyhaemoglobin and carbon monoxide in smokers and non-smokers was investigated. Both methods are of high analytic and diagnostic validity. Precision and accuracy fullfil the essential requirements.

Effect of cigarette smoking on white blood cells and erythrocyte enzymes.

Healthy volunteers smoked 21 to 26 cigarettes containing different amounts of condensate (tar) and nicotine for 16 wk. Enzymes and metabolites of erythrocyte metabolism were not influenced, with the exception of a slight inhibition of delta-aminolevulinic acid dehydratase. Hematological parameters were normal except the white blood count, which was elevated in smokers but remained within the normal range.
