Anticholinergic activity and pharmacokinetic parameters of agent SS-68 with properties of class III antiarrhythmic drugs
It was shown that the indole derivate SS-68 (50 and 250 μg/kg intravenous) in acute experiments on cats with neurogenic atrial fibrillation (AF) has a dose-dependent antiarrhythmic action which is associated with the neurotropic influence of this substance, since the suppression of the AF coincides with its anticholinergic effect observed for more than 2 hours, but cardiotropic action at this time was not observed. High antiarrhythmic activity of SS-68 to neurogenic AF may be due to the IKAch inhibition and blockade of M2-cholinergic receptor
Part I
The problem of heart rhythm disturbances is one of the most urgent topics of modern cardiology. According to the currently available concepts, 1,2- and 1,3-disubstituted aminoindole derivatives, which compound 2-phenyl-1-(3-pyrrolidin-1-il-propyl)-1H-indole hydrochloride (SS-68) belongs to, are a promising chemical group in terms of their cardio-pharmacological activit
Pharmacokinetic studies derived indole SS-68 with antiarrhythmic and antianginal properties
A method of quantitative determination of SS-68 derivative of indole in rabbit blood plasma by high performance liquid chromatography with tandem mass spectrometric detector (HPLCMS/ MS). Conducted pharmacokinetic studies SS-68 in the body of rabbits. Set the main pharmacokinetic parameters of the substance that allow you to optimize the future use of it’s as a potential drug in cardiology practic
Anti-inflammatory and analgesic propertiesof SS-68 indole derivative
The experiments with rats show that when administered intravenously (5 mg/kg) and intragastrically (5, 10, 15 and 20 mg/kg), SS-68 compound exerts an antiinflammatory effect (AIE) on models of acute inflammation, caused by carrageenin and serotonin, and exerts no AIE in case of edema induced by complete Freund‘s adjuvant (CFA) and histamine, except for intragastric administration at a dose of 20 mg/kg. By its antiphlogogenic effect in case of carrageenin and serotonin edemas, SS-68 is comparable to diclofenac (5, 10 and 15 mg/kg intragastrically) and indomethacin (10 mg kg intragastriccally), and exceeds piroxicam (20 mg/kg intragastrically). By reference to its therapeutic index (TI), in the first case SS-68 exceeds diclofenac, indomethacin and piroxicam 2.2, 15.6 and 5.6 times, and in the second case it exceeds them 1.8, 12.8 and 4.4 times, respectivel
The influence of the vagus nerve and indole derivative SS-68 on excitation processes in the SA node
The aim of the study was to identify the components of the takeover process of central rhythmogenesis by the SA node in the conditions of atrial fibrillation when stimulating the vagus nerve and using substance SS-6
Distance learning: opportunities and challenges in quarantine.
The urgent introduction of distance education into the learning process due to the COVID-19 pandemic has become a spontaneous experiment, requiring urgent decisions, effective mechanisms to implement into the educational process and analysis of ongoing educational process. The possibilities of modern digital technologies made it possible to quickly set up the information component of education and to controle student’s knowledge. A detailed analysis of the communication between the faculty members of the department among themselves and analysis of the features of teaching and self-education of students in the field of medical radiology and oncology based on answers and comments with using Google classroom, Socrative, Messenger Telegram, etc. was made. Issues of communicative interaction between faculty members and students, psychological aspects of distance communication, language of instruction, logistics of distance education and methodological problems are described in details. It has been suggested that distance education may be equally effective for theoretical subjects in full-time study form, but when studying clinical disciplines, the priority should be given to traditional methods of teaching, involving student's bedside training. Taking into account technical possibilities and high risk of development of extreme and emergency situations, it is suggested to introduce permanent readiness for distance education, to create all – Ukrainian distance imitation service of patients’ follow-up. The importance of using the state language in training as the basis for mastering the professional Ukrainian and English language as the basis for mastering international medical experience is indicated
