[Frequency of detection the of Brugada syndrome signs in the course of ECG registration].

The aim of the study was to assess prevalence of the Brugada syndrome during carrying out ECG in the conditions of medico-sanitary division of a large industrial enterprise. Signs of the Brugada syndrome were found on 20 of 42779 ECGs (0.047%) registered during 1 year in patients aged 22-68 years. Type 2 syndrome was noted in 4 patients, others had type 2 of the syndrome. Men comprised 90% of patients. At 24 hour ECG monitoring paroxysm of nonsustained ventricular tachycardia was registered in 1 patient during night hours. Cases of sudden death were registered in families of 3 patients (all men older than 45 years). Four patients experienced syncopi clinical picture of which resembled more neurocardiogenic but not arrhythmic attacks. Thus prevalence of the Brugada syndrome in our population was quite low.

[Role of incomplete dietary protein in experimental formation of gallstones]. / Rol' nepolnotsennogo belka pishchi v obrazovanii zhelchnykh kammei v éksperimente

The influence exerted by the quality of alimentary protein on the composition of the secreted bile, morphology of the liver and gallbladder, as well as on the formation of gallstones was studied in experiments with rats and hamsters. It is shown that with inclusion in an experimental fat-free ration of qualitatively incomplete protein gelatin (instead of caseine) the frequency of the gallstones formation increases by almost 6 times. In animals this is attended by a reduced concentration of a number of major bile components. Upon feeding for 2 weeks on lithogenic ration with gelatin morphological investigations disclose inflammatory changes in the gallbladder wall, and after a lapse of 3 weeks--multiple exulcerations in the mucosa and a dense gross sediment in the gallbladder lumen.
