Leonurus cardiaca L. (Lamiaceae) is used traditionally for its sedative, hypotensive and cardiotonic effects. Due to the lack of clinical data regarding its effect in patients, a study was carried out to assess the clinical efficacy of Leonurus oil extract (LOE) in patients with arterial hypertension stages 1 and 2, accompanied by anxiety and sleep disorders. Fifty patients were treated for 28 days with 1200 mg LOE per day. Positive effects of LOE on psycho-emotional status and arterial blood pressure in patients with stage 1 hypertension were observed 1 week earlier than in patients with stage 2 hypertension. According to the Clinical Global Impression (CGI) scale, a significant improvement in the symptoms of anxiety and depression was observed in 32% of patients, a moderate improvement in 48% and a weak effect in 8%; 12% of patients did not respond to therapy. Side effects were minimal in all groups. Leonurus oil extract may therefore be a potentially effective therapeutic agent for patients with arterial hypertension and concurrent psycho-neurological disorders.

A new highly sensitive HPLC technique for the analysis of naltrexone and its active metabolite 6-b-naltrexol in the blood plasma of patients with drug addiction has been developed. The levels of naltrexone and 6-b-naltrexol in the blood plasma of patients after hypodermic implantation of prodetoxon depot tablets, a new domestic form of naltrexone, have been determined. Fig. 3. Calibration curves for the quantitative determination of (1 ) naltrexone and (2 ) 6-b-naltrexol in the blood plasma.

Патогенез пародонтита включает сложный иммунный воспалительный каскад, который инициируется бактериями биопленки, а восприимчивость или вероятность развития заболевания определяется реакцией организма человека, в частности, величиной воспалительного ответа и дифференциальной активацией иммунных путей. Цель исследования -разработать прогностическую модель для оценки риска развития тяжелой степени хронического генерализованного пародонтита в зависимости от содержания фактора некроза опухоли-α (ФНО-α) в экссудате пародонтального кармана (ПК) пациента. При клинико-инструментальном обследовании 537 пациентов с хроническим генерализованным пародонтитом и метаболическим синдромом установлено, что уровень повышения ФНО-α в содержимом ПК коррелировал со степенью тяжести хронического генерализованного пародонтита (ХГП): более высокие значения цитокина соответствовали более тяжелой степени. Разработанная в программе Statistica.10 прогностическая модель дала возможность использовать уровень ФНО-α в содержимом ПК пациента в качестве прогностического критерия течения ХГП. Определено критическое значение, при превышении которого с диагностической чувствительностью 91,2% и специфичностью 70,8% можно заключить о высоком риске развития тяжелой степени ХГП. Созданное окно в программе Microsoft Exсel 2010 позволяет автоматически рассчитывать риск развития тяжелой степени ХГП в зависимости от индивидуального значения концентрации ФНО-α в содержимом ПК пациента, что делает данную модель удобной для применения врачами-стоматологами.The pathogenesis of periodontitis involves a complex inflammatory cascade initiated by biofilm bacteria. The susceptibility to or the risk of developing the disease is determined by the body's response to the invasion, specifically, by the strength of the inflammatory response and the differential activation of immune pathways. In this paper, we propose a model for predicting the risk of severe chronic generalized periodontitis (GCP) in patients with metabolic syndrome based on the levels of tumor necrosis factor alpha (TNF-α) in the periodontal pocket exudate. The analysis of oral cavity cytokine profiles conducted in 537 patients with GCP and comorbid metabolic syndrome showed that increased TNF-α correlated with the severity of GCP: higher levels of TNF-α were observed in patients whose condition was more severe. The prognostic model built in Statistica. 10 allowed us to use TNF-α as a prognostic criterium for GCP severity. We determined the cut-off point above which a high risk of severe GCP can be concluded with 91.2% sensitivity and 70.8% specificity. The spreadsheet in Microsoft Exсel 2010 automatically computed the risk of severe GCP from a patient's TNF-α concentrations in the PP, which makes the model convenient for routine clinical use in dentistry.Ключевые слова: пародонтит, метаболический синдром, цитокины, фактор некроза опухоли, ФНО, прогностическая модель

Background High values of endogenous levels of magnesium (Mg) in the body and mechanisms of homeostasis regulation make it difficult to assess the bioavailability of these drugs. The aim of this study was to assess the Mg concentration in blood in volunteers and in erythrocytes in patients with hypomagnesemia. Methods The study included 20 healthy volunteers and 62 patients with chronic heart failure (CHF) I–III functional class (FC) NYHA classification. We studied the composition of Mgorotate and Mgorotate plus potassium (К)orotate. Blood sampling was carried out at 8 a.m. and within 10 h after administering the drugs. Measurement of Mg pharmacokinetic parameters: AUC (concentration of the active substance-time), and Cmax (maximum concentration) in volunteers and measurement of the concentration of Mg in erythrocytes of patients. Results The results indicated that both the AUC in volunteers and concentration of Mg in erythrocytes of patients are comparable, and the differences are not statistically significant. Conclusions The study showed that the standard method of calculating the AUC (total serum Mg) is insufficient for comparative evaluation of Mg absorption due to the high levels of its endogenous content and a small increase in concentration after taking the drugs. It is advisable to assess the concentration of Mg in the red blood cells of patients.
