Spirometric examinations are suitable for the diagnosis of airway obstruction, but not of pulmonary emphysema. Whole body plethysmography, in contrast, is the most reliable diagnostic procedure for both conditions, both qualitatively and quantitatively. The basic treatment of any form of airway obstruction consists in the inhalation of beta-2-sympathomimetic drugs; theophyllines are also good bronchodilators, but are less powerful than beta-2-sympathomimetics. Glucocorticoids must always be given when bronchitis also presents, which is only rarely treatable with antibiotics alone. Although regression of pulmonary emphysema is not possible, progression of the destructive process would appear to be inhibited by intensive treatment of the inflammatory bronchitis. Only in the case of patients with congenital alpha-1-antitrypsin deficiency is it possible to administer such causal treatment in the form of substitution therapy. Surgical treatment can be considered only in the case of bullous pulmonary emphysema.

Flow-volume values and their changes in response to salbutamol and methacin inhalations were studied with the help of a pneumotachograph in 69 patients with anthracosilicosis stage I, and in 70 patients with chronic dust bronchitis stages I and II. Pneumotachography was shown to extend diagnostic potentialities in the detection of ventilation insufficiency in patients with dust pulmonary pathology, making it possible to determine not only a degree but also a site of obstructive disorders. Disorders of the sympathetic and parasympathetic bronchial innervation and associated biochemical mechanisms were important in the mechanism of bronchospasm development. Pneumotachography was recommended in combination with bronchospasmolytic drugs of sympathomimetic and cholinolytic action for elucidation of the mechanism of disorders of the bronchial tone, a choice of adequate therapy and assessment of its efficacy.

51 patients suffering from chronic spastic bronchitis were treated with acupuncture over a period of three years. The patient group consisted of 15 men and 36 women varying in age from 19 to 75 years, with an average age of 45.7 years. The therapy program consisted of 2 or 3 months of acupuncture treatment in alternation with an equal period (2 or 3 months) of recess during which no treatment was administered. Before acupuncture, patients had taken corticosteroids either orally and/or intramuscularly for a period of 2 to 24 years. For those taking corticosteroids orally the daily dosages ranged from 10 to 40 mg Encorton (Polfa, Poland). The patients took intramuscular injections of 60 to 80 mg Kenalog (Squibb) every two or three weeks. Of the 51 patients, 36 completed 3 years of acupuncture treatment. It was found that 63.8% of the patients were able to eliminate corticosteroids for the last part of this study period, i.e., from 3 to 26 months (average period 10.2 months). In 13.9% of the patients the dose of intramuscular injection of corticosteroids was reduced by over 60% during acupuncture treatment. In 16.7% of the patients, the oral administration of corticosteroids was only during lung infections with dyspnoea. In 7 patients (i.e., in 19.5% of the 36 patients) administration of all previously required drugs (i.e., corticosteroids, mucolytic drugs, appropriate antibiotics, aminoxanthines, sympathomimetic beta-agonists, sedation drugs, aerosolized drugs with corticosteroids, and nebulized drugs) during the last 3 to 15 months of this study period (average of 9.8 months) were no longer required.

The herb Scoparia dulcis L. is used in Brazilian folk medicine to treat bronchitis, gastric disorders, haemorrhoids, insect bites and skin wounds, and in oriental medicine to treat hypertension. A previous study has shown that extracts of S. dulcis have analgesic and anti-inflammatory properties; in this work the sympathomimetic activity of an ethanolic extract of Scoparia dulcis L. has been investigated in rodent preparations in-vivo and in-vitro. Administration of the extract (0.5-2 mg kg-1, i.v.) to anaesthetized rats produced dose-related hypertension blocked by the alpha-adrenoceptor antagonist prazosin (1 mg kg-1). Partition of the extract in chloroform-water yielded an aqueous phase 20 times more potent than the extract; this produced hypertension in either reserpine-treated or pithed rats. In untreated and reserpine-treated rats the same fraction (1-3 x 10(3) micrograms mL-1) produced concentration-dependent contractions of the vas deferens musculature parallel to those obtained with noradrenaline (10(-8)-10(-4)M). Prazosin (10(-7)M) reduced the maximum contractile effect of the aqueous fraction, and shifted the concentration-response curves for noradrenaline to the right. The aqueous fraction (25 and 50 micrograms mL-1) increased the inotropism of electrically driven left atria of rats, the effect being blocked by propranolol (0.4 microgram mL-1). In preparations of guinea-pig tracheal rings the aqueous fraction (1-3 x 10(3) micrograms mL-1) relaxed the muscle contraction induced by histamine (10(-4) M) in proportion to the concentration. The effect was antagonized competitively by propranolol (1.5 microM). High-performance liquid-chromatographic analysis of the aqueous fraction revealed the presence of both noradrenaline and adrenaline in the plant extract. The results indicated that both catecholamines may account for the hypertensive and inotropic effects obtained after parenteral administration of S. dulcis extracts. This sympathomimetic activity is, however, unrelated to the previously reported analgesic and anti-inflammatory properties of the plant extract, but may explain its effectiveness upon topical application in the healing of mucosal and skin wounds.
