[Pulmonary tuberculosis in youth treated at the Clinic of Lung Diseases and Tuberculosis in 1990-1994]. / Zapadalnosc na gruzlice pluc miodych leczonych w klinice chorób pluc i gruzlicy w latach 1990-1994.

An analysis of pulmonary tuberculosis morbidity risk factors has been presented among patients treated in the Clinic during the period 1990-94. Among the morbidity risk factors, apart from the presence of concomitant diseases, the deterioration of the standard of living of the population and the low level of health education, observed even among people with higher education, was of prime importance, followed by a limited number of radiographic, catastral examinations.

[Difficulties with diagnosis of lung cancer]. / Trudnosci z rozpoznaniem raka pluc.

52 year old patient with pulmonary tuberculosis in the past, was admitted to hospital because of massive hemoptysis. The cause of hemoptysis was not find during routine examinations. TK of lungs revealed only cirrhosis and bronchiectases in upper right lobe. During thoracotomy lung cancer was recognised.

[Tuberculous meningitis--a diagnostic and treatment problem]. / Gruzlicze zapalenie opon mózgowo-rdzeniowych--problem diagnostyczny i leczniczy.

Tuberculous meningitis is one of the most serious form of tuberculosis. The delay in diagnosing of tuberculous meningitis results in high mortality. An early diagnosis allows to achieve successful effects of treatment.

[Blood platelets as one hemostatic indicator in patients with bronchial asthma]. / Plytki krwi jako jeden z wykladników hemostazy u chorych na astme oskrzelowa.

Phospholipids forming blood platelets membrane are substrates for oxidative phosphorylation in electric and chemical activation of these cells. Beneficial effect of corticosteroids on the course of asthma is connected with inhibition of phospholipase A2. This enzyme is responsible for the generation of allergic reaction membrane mediators like leukotrienes, prostaglandins and other lipoxygenase products. Three groups of asthmatic patients were observed: I group--patients with mild asthma, II group--patients with moderate asthma, III group--patients with severe, corticosteroid-dependent bronchial asthma. Changes of platelets membrane phospholipids structure in these groups of asthmatic patients were analyzed. There were significant differences in membrane phospholipids structure between II and III group of patients and control subjects (p < 0.01).

The effect of calcium ions on the intensity of peroxidation processes and the severity of ethanol-induced injury to the rat's gastric mucosa.

The effects of verapamil (Isoptin Knoll) and calcium glubionate (Calcium Polfa) were studied on the generation of free radicals and activity of anti-oxidant enzymes in rat's gastric mucosa following the oral administration of 50% ethyl alcohol. Ethanol in this concentration caused injury to gastric mucosa as well increased the levels of peroxidation products (malonyl dialdehyde, hydroperoxides and conjugated dienes); at the same time a decreased enzyme activity was observed (superoxide dismutase, peroxidase, glutathione peroxidase, glutathione reductase, catalase). Verapamil administered before ethanol increased the ulcerogenic activity of alcohol, increased the activity of the studied antioxidant enzymes (except catalase) and caused the decrease in the levels of peroxidation products in gastric mucosa. Calcium glubionate increased the enzyme activity and showed some protective effect on gastric mucosa.

The effect of ethyl alcohol on peroxidation processes and activity of antioxidant enzymes in rat's gastric mucosa.

The severity of damage to gastric mucosa and the levels of malonyl dialdehyde (MDA), hydroperoxides, conjugated dienes (C.D.) as well as the activity of catalase (EC 1.11.1.6), peroxidase (EC 1.11.1.7), glutathione peroxidase (EC 1.11.1.9) and superoxide dismutase (EC 1.15.1.1.) in rat's gastric mucosa were assessed 2 hours after the oral administration of 50% ethyl alcohol by means of a stainless steel tube. It was found that 50% ethanol administered per os caused numerous ulcerous changes in gastric mucosa, increased the levels of MDA, hydroperoxides, both isoenzymes of superoxide dismutase (Cu, Zn SOD and Mn SOD), glutathione peroxidase and glutathione reductase. The interpretation of the phenomenon was presented, emphasizing the protective role of antioxidant enzymes counteracting the formation of ulcers in gastric mucosa.
