[A case of thoracic actinomycosis].

A case of thoracic actinomycosis manifest as round shadow in the lung is described. Diagnosis was based on the presence of actinomycetes in a transthoracic lung biopsy sample. Treatment for 3 months resulted in recovery.

[The clinical and endoscopic state of the esophagus in patients with asthma concurrent with chronic opisthorchiasis].

The frequency and pattern of manifestations of gastroesogageal reflux disease were studied in asthma concurrent with chronic opisthorchiasis. One hundred and fifty patients (52 males and 98 females) aged 14 to 60 years (mean age 43.18 +/- 10.

[Trophologic insufficiency and absorptive function of small intestine in patients with chronic obstructive pulmonary disease].

The study included 93 patients with grade 1-3 chronic obstructive pulmonary disease (COPD) in the stable clinical phase. Absorptive function of the small intestine was evaluated by biochemical methods and with the use of radionuclides; plasma tumour necrosis factor-alpha (TNF-alpha) levels were measured by an enzyme immune-assay. Trophologic status in 44% of the patients with COPD was unaltered whereas 14% had an excessive body weight.

[Erosive lesions in the gastroduodenal zone of patients with bronchial asthma].

The purpose of the investigation was to study the frequency and clinicomorphological features of erosive lesions (EL) in the gastroduodenal zone (GDZ) of patients with bronchial asthma (BA). One hundred and sixty-three patients suffering from allergic BA of different degrees of severity were examined. The examination included clinical evaluation of the GDZ, esophagogastroduodenoscopy with gastric and duodenal mucosal biopsy, and subsequent analysis of the biopsy samples using histological, histochemical, morphometric methods, and electron microscopy.

[The vasomotion characteristics in isolated segment of the tail artery under conditions of slow constant increase of the perfusion pressure].

In vitro, the Wistar rat tail artery segments were perfused with the Crebs-Henselite solution. Under the conditions of perfusion pressure increasing from 0 to 110 mm Hg with the velocity of 5 mm Hg/min, the "diameter-pressure" curves were obtained. Changes in the vessel diameter during increase of pressure in the vessel were accompanied by vasomotions.
