[Comparative analysis of antiarrhythmic and proarrhythmogenic effects of drugs for neuroleptanalgesia, ataralgesia, and antidepranalgesia in experimental acute myocardial infarction].

Proarrhythmogenic and antiarrhythmic effects of drugs for neuroleptanalgesia (NLA), ataralgesic (ATA) and antidepranalgesia (ADA) in chronic experiments on sleepless rabbits with acute myocardial infarction, with and without tachyarrhythmias, were studied using ECG, intraventricular electromanometry and tetropolar rheography. NLA (phentanylum, 1 microg/kg + droperidol, 5 microg/kg), ADA (pyrazidole, 1 mg/kg + tramal, 1 mg/kg) and ATA (diazepam, 1 mg/kg + promedol 0.5 mg/kg) produce antiarrhythmic effect with maximum manifestation of NLA on the 3rd day, and of ATA and ADA on 3-5th day.

[A comparative study of lymphocytic apoptosis and ventilation disorders in patients with pulmonary tuberculosis].

Due to the increasing interest in studies of apoptosis (programmed cell death) in the pathogenesis of many diseases and to the emergence of data on the direct impact of apoptotic disorders on the course of bronchial asthma and the magnitude of the obstructive syndrome, this study was undertaken to investigate apoptosis in patients with new-onset pulmonary tuberculosis who had varying bronchial obstructive syndrome. Twenty-eight patients with new-onset tuberculosis, including 25 (89.3%), 2(7.

[Characteristics of the effect of different cardiovasotropic preparations on the contractility of separate sections of the myocardium in acute coronary occlusion].

In acute experiments on cats, the effect of nitroglycerin (0,5 mg/kg), obsidan (0,5 mg/kg) and adrenaline (0,005 mg/kg) on the contractility of various segments of the myocardium in acute ischemia state was studied. It is shown that nitroglycerin increases the contractility of the border zone and decreases the compensatory hyperfunction of intact myocardial zones. Obsidan reduces the contractility of all the zones and adrenaline suppresses the border zone contractility despite the marked growth of contractile function of the intact zones and of the heart on the whole.
