    Streszczenie angielskie: Background. Atrial fibrillation (AF) is the most common sustained tachyarrhythmia, which results in a 20 p.c. to 30 p.c. reduction in stroke volume and cardiac output in normal individuals. Although there were a large number of echocardiographic studies that focused on left ventricular function, right ventricular function has not been widely studied before and after cardioversion of AF. Aim. The aim of this study was to investigate the potential effects of carioversion on right ventricular function in patients with AF by tissue Doppler echocardiography. Methods. Fifteen patients with electrocardiographic evidence of AF 3 weeks duration and 12 age- and sex-matched healthy controls were included. Right ventricular systolic and diastolic functions were determined by conventional and tissue Doppler echocardiography before, 24 hours and one month after successful cardioversion of AF. Results. One month after restoration of sinus rhythm, left and right atrial dimensions significantly decreased in patietns with AF (p 0.01 and p 0.05, respectively). Heart rate decreased significantly already after 24 hours (p 0.01) and one month later remained significantly slower than during AF (p 0.01). Right ventricular filling parameters determined by conventional echocardiography improved after cardioversion. In the tissue Doppler echocardiography, the peak systolic velocities measured at the lateral corner of the tricuspid annulus were significantly lower in AF patients than in controls (p 0.001), whereas after cardioversion significantly increased...

    Streszczenie angielskie: Background: One of the serious potential complications of complex congenital heart defect (CHD) is bacterial endocarditis. Right sided endocarditis accounts for 5-10 p.c. of all cases of infective endocarditis, with the tricuspid valve more frequentlly affected than the pulmonary valve. Pulmonary artery involvement in bacterial endocarditis is very rare, but when it exists it is almost always associated with endocarditis of the pulmonary valve: isolated pulmonary artery vegetations have not previously been reported before. Case Report: A 6-year-old boy with atrial septal defect (ASD), ventricular septal defect (VSD), coarctation of the aorta (CA), persistent ductus arteriosus (PDA) and pulmonary hypertension, who had been operated for closure of PDA, correction of CA and pulmonary artery banding, was readmitted with bacterial endocarditis. In surgery, the VSD was closed with a Dacron patch using interrupted pledget buttressed sutures, and the ASD was closed using primary sutures. After debanding, while pulmonary arteriotomy was performed for patch angioplasty, we observed that the entire pulmonary artery trunk, right and left pulmnary artery branches, were filled with a solid mass, which was successfully treated by surgical excision. Conclusion: With ongoing improvements in diagnostic tools, especially in echocardiography, antibiotic therapy and surgery, CHD can now be treated successfully in early infancy or childhood.

    Streszczenie angielskie: The aim of our study was to determine whether alterations of the vitamin D-endocrine system and the renin-angiotensin-aldosterone system occur in male obesity and influence each other. 32 ibese male subjects and 21 age-matched healthy male subjects were enrolled in the study. The parameters measured included serum total calcium (Ca), ionized calcium, magnesium (Mg), phosphorus (P), 25-hydroxyvitamin D (25-OHD), supine and upright aldosterone and renin activity, and urinary calcium, magnesium, and phosphorus. Serum total Ca and ionized calicum were slightly, but not significantly lower in obese subjets compared to controls, whereas serum magnesium phosphorus and PTH levels were significantly higher in the obese subjects. Mean urinary calcium and Mg were not significantly different, while urinary P was significantly higher in obese subjects. Mean serum 25OHD was significantly lower in obese subjects. Supine and upright aldosterone and renin were unrelated to BMI or fat mass. Supine aldosterone correlated with serum total calcium, ionized calcium and supine renin activity, but not with other minerals, PTH or 25OHD, whereas upright aldosterone did not correlate with other parameters. Supine renin activity did not correlate with any parameters, whereas upright renin correlated with serum Mg an PTH. There were significant correlations between PTH and BMI or fat mass. Urinary Mg was also related to both BMI and fat mass. Male obesity is associated with increased serum Mg, P, PTH and urinary P and lower supine aldosterone and 25OHD, but unchanged serum and urinary Ca.

    Streszczenie angielskie: Background: The purpose of this study was to prospectively evaluate the effectiveness of CT-guided transthoracic fine needle aspiration in the diagnosis of pulmonary lesions and to determine the complication rate of this procedure. Material/Methods: A prospective review was udnertaken of 316 patietns who underwent CT-guided transthoracic fine needle aspiration performed at our center between October 2000 and April 2001. Twenty-two patietns were excluded because no final diagnosis was achieved. The present study included 294 patietns. All fine needle aspirations were performed with a 22-gauge aspirating needle under CT guidance. Results: An accurate diagnosis was made in 228 of 259 malignant lung lesions (88 p.c.). A speicific diagnosis was obtained in 34.3 p.c. of the benign lesions. The sensitivity for malignancy and specificity for benign lesions were 88 p.c. and 100 p.c., respectively. Positive and negative predictive values were 100 p.c. and 53 p.c., respectively. Tehre was no fals-positive diagnosis for malignancy. Sensitivity was 87 p.c. for centrally located lesions and 89.3 p.c. for peripherally located lesions (p 0.05). Complications included pneumothorax, 24 of 294 cases (8.2 p.c.); chest tube, 3 cases (12.5 p.c.); minor hemoptysis, 5 cases (1.7 p.c.); and pulmonary hemorrhage, 4 cases (1.4 p.c.). Conclusions: Our results suggest that this procedure has high diagnostic accuracy and an acceptable rate of complications.

    Streszczenie angielskie: The in vitro and in vivo effects of some drugs on rat erythrocytes 6-phosphogluconate dehydrogenase were investigated in this study. Rat erythrocyte 6-phosphogluconate dehydrogenase was partially purified with ammonium sulfate precipitation. The enzyme activity was determined by Beutler's method. Some drugs such as ampicilin, amikacin sulfate, and netilmicin sulfate inhibited the enzyme activity in in vitro conditions, while metamizole activated it. The I50 values of the inhibiting drugs were 66.2, 5.836, and 0.963 mM, respectively. For the drugs having low I50 values (drug concentrations which produce 50 p.c. inhibition) (amikacin sulfate and netilmicin sulfate), in vivo studies were performed in rats (Sprague-Dawley). Amikacin sulfate at 64 mg/kg inhibited the enzyme activity significantly (p 0.05) 2 h after dosing. Netilmicin sulfate at 6.4 mg/kg also inhibited the enzyme significantly (p 0.05) 4 h after dosing. Amikacin sulfate and netilmicin sulfate inhibited rat erythrocyte 6-phospogluconate dehydrogenase both in vivo and in vitro. The enzyme was inhibited in vitro by ampicillin and activated in vitro by metamizole.
