The purpose of this study was to investigate the microbiological (number of viable lactic acid bacteria and bifidobacteria), physicochemical (dry matter, protein and fat contents, titratable acidity, and pH), and sensory characteristics (appearance of coagulum, taste and aroma, structure at cutting, color, and consistency at shattering) of probiotic Bulgarian yoghurts obtained by ultrafiltration of goat's milk. These yoghurts were obtained using volume reduction ratios of 2 and 3 with the probiotic starters MZf, MZf +  BB - 87, and MZf +  LAB - 8. The increase in the level of the concentration by ultrafiltration led to an increase in the dry matter, protein and fat contents of the yoghurts, in the number of lactic acid bacteria and titratable acidity, and to a decrease in the pH.

Aim: To investigate the efficacy and safety of nebulized budesonide and systemic glucocorticosteroids (GCS) (SGCS) in the treatment of an exacerbation of chronic obstructive pulmonary disease (COPD) and their effects on the serum concentration of soluble leukocyte differentiation antigens.

Materials And Methods: Seventy-eight hospitalized patients with an acute exacerbation of COPD were randomized into two groups: 1) 37 patients took nebulized budesonide 4 mg/day; 2) 41 patients received intravenous prednisolone. The symptoms of COPD, forced expiratory volume in one second (FEV1) and other spirometric indicators, peripheral blood oxygen saturation (SpO2), and adverse events were studied.
