[The effect of air pollution on the occurrence of respiratory tract diseases in children in Slovakia].

In 1986 and 1987 the authors investigated the incidence of diseases of the respiratory system in children in 13 areas with a contaminated atmosphere. The morbidity was compared with the incidence of diseases in children living in an area with a relatively clean living environment. In 1986 the group comprised 8,973 children, in 1987 9,409 children aged 7-14 years. The morbidity was recorded by health community paediatricians according to the International Classification of Diseases and evaluated by means of the annual incidence. The authors calculated also the mean period of illness of the airways. In 11 contaminated areas they found a significantly higher incidence of respiratory diseases (p less than 0.01) and higher mean duration of respiratory diseases, as compared with the control area.

[Respiratory tract diseases in relation to climate, air pollution and city structure].

During one year investigations were made in the city of Kassel to collect data on respiratory diseases, immission rates and climate. The frequency of disease was registered by doctors and parents. All of them prepared daily lists. Parallel immission and climatic conditions were measured. From this a typical annual variation was found that governed the influence of weather and air pollution in disease. Moreover, through daily interpretation more detailed results the connection between disease rates and air pollution could be found, even throughout the city.

[Expectorant herbal medicines in respiratory tract diseases in tobacco smokers].

Cigarette smoking can cause a variety of pulmonary and cardiovascular diseases like: bronchitis, emphysema, myocardial infraction as well as lung cancer. The tar phase precipitates in the respiratory tract, inactivating the ciliated epithelium and inhibiting the self-cleaning of bronchia. Herbal remedies increase mucosa secretion and hence facilitate coughing up the secrete residual. The action of expectorant herbs results primarily from their influence on the gastric mucosa and following a reflex stimulation which leads to an increase in secretion of the bronchial glands. Volatile-oil type expectorant herbs have shown a direct stimulatory effect on the bronchial glands by means of local irritation, accompanied with antibacterial and spasmolytic activity. Expectorant herbs containing saponins function reduce the surface tension of the secretions facilitating their separation from the mucous membranes.
