Ультратонкие волокна на основе биополимера полигидроксибутирата (ПГБ), модифицированные наноразмерными модификациями диоксида титана

The technological characteristics of spinning polymer solutions (viscosity, conductivity) and the parameters of the EPI - a process based on poly-3-hydroxybutyrate modified with nanoscale titanium dioxide were optimized. The composite materials were studied by X-ray diffraction, differential scanning calorimetry, infrared spectroscopy and physico-mechanical analysis (tensile test, elongation). A significant improvement in their physical and mechanical properties (breaking length, elongation) and resistance to the maturing were found.Оптимизированы технологические характеристики формовочных полимерных растворов (вязкость, электропроводность) и параметры ЭФВ (электроформование волокнистых материалов) - процесса на основе поли-3-гидроксибутирата, модифицированных наноразмерным диоксидом титана. Композитные материалы изучены методами рентгенографии, дифференциально-сканирующей калориметрии, ИК-спектроскопии и физико-механического анализа (испытания на разрыв-удлинение). Установлено существенное улучшение их физико-механических характеристик (разрывная длина, относительное удлинение) и стойкости к старению

EFFICACY AND SAFETY OF ALBAREL IN PATIENTS WITH MILD, MODERATE AND SEVERE HYPERTENSION

The aim of the study was to evaluate the efficacy and safety (influence on carbohydrate, lipid and mineral metabolism, as well as nitrogen-excreting function of kidneys) of monotherapy with rilmenidine in patients with mild to moderate AH, as well as treatment of patients with severe AH as multiple combined treatment. 43 patients with essential AH I-HI degree, aged 22 to 79, were enrolled in this open label study after signing an informed consent form. Enrolled patients were divided into 2 groups. Group 1 included 20 outpatients. They received monotherapy with rilmenidine 1 mg daily. Duration of treatment was 12 weeks. Group 2 was comprised of 23 subjects admitted to an in-patient clinic. Those subjects received Albarel 1 mg or 2 mg daily as a component of multiple antihypertensive therapy. Albarel was administered 7-10 days following the admission to clinic as a second to fifth hypotensive drug. Albarel's combinations with diuretics, ACE inhibitors, calcium antagonists, beta-blockers. The result is - monotherapy with Albarel 1-2 mg daily allows to achieve target BP in 77, 8 % patients with mild to moderate AH. With Albarel as a component of multiple therapy target BP is achieved in 65, 2 % patients with severe AH. Effectively decreasing BP Albarel does not change its daily profile. It has no influence on renal function, carbohydrate metabolism, and electrolyte content of blood. Albarel is well tolerated. Adverse effects included mouth dryness and drowsiness, was noted in 2, 33 % cases and did not require drug withdrawal
