ВЛИЯНИЕ ПОЛИФЕНОЛЬНЫХ СОЕДИНЕНИЙ, ВЫДЕЛЕННЫХ ИЗ CARTHAMUS TINCTORIUS И CALENDULA OFFICINALIS L., НА ФУНКЦИОНАЛЬНУЮ АКТИВНОСТЬ ИММУНОКОМПЕТЕНТНЫХ КЛЕТОК В УСЛОВИЯХ ЦИТОСТАТИЧЕСКОЙ ИММУНОСУПРЕССИИ

The purpose of the study – to study the effect of polyphenolic compounds extracted from the flowers of safflower oil and calendula, the functional activity of immune cells in cytotoxic immune suppression.Conventional methods determined the total number of splenocytes, relative (%) and absolute (106), the number of antibody-forming cells (AFC) in the spleen of mice by local hemolysis by Cunningham.Evaluated the effect of compounds of natural origin on the cellular immune response in the delayed-type hypersensitivity (DTH). Phagocytic activity of peritoneal macrophages was determined by the method based on the intensity of their capture ink particles. We studied the functional activity of peritoneal macrophages by NBT test (spontaneous and stimulated). Studies were conducted on male mice Category 1 (conventional linear mouse) line CBA/CaLac aged 2–2.5 months, weighing 20–22 g. After the introduction mice line CBA/CaLac of polyphenolic compounds derived from flowers of Carthamus tinctorius and flowers of Calendula officinalis L. during the 5-day course in dose 50 mg/kg was observed stimulation of the humoral immune response (total number of splenocytes, the number of antibodies in the spleen cells) and the functional activity of macrophages and Immunomodulating effect on the humoral immunity and the functional activity of macrophages after a single injection of cyclophosphamide in dose 250 mg/kg. Immunotropic activity of polyphenolic compounds is higher than that those of the reference product of tincture of Echinacea purpurea.Цель исследования – изучить влияние полифенольных соединений, выделенных из цветков сафлора красильного и календулы лекарственной, на функциональную активность иммунокомпетентных клеток в условиях цитостатической иммуносупрессии. Общепринятыми методами определяли общее количество спленоцитов; относительное (%) и абсолютное (106) количество антителообразующих клеток (АОК) в селезенке мышей методом локального гемолиза по Cunningham. Оценивали влияние соединений природного происхождения на клеточный иммунный ответ в реакции гиперчувствительности замедленного типа (ГЗТ). Фагоцитарную активность перитонеальных макрофагов определяли методом, основанным на интенсивности захвата ими частиц туши. Изучали функциональную активность перитонеальных макрофагов с помощью НСТ-теста (спонтанного и стимулированного). Исследования были проведены на мышах-самцах 1-й категории (конвенциональные линейные мыши) линии CBA/CaLac в возрасте 2–2,5 мес и массой тела 20–22 г.После введения мышам линии CBA/CaLac 5-дневным курсом в дозе 50 мг/кг массы тела полифенольных соединений, выделенных из цветков сафлора красильного и календулы лекарственной, наблюдалась стимуляция гуморального иммунного ответа (общее количество спленоцитов, количество антителообразующих клеток в селезенке) и функциональной активности перитонеальных макрофагов. Полифенольные соединения исследуемых объектов оказывают иммунокорригирующее действие на гуморальный иммунитет и функциональную активность перитонеальных макрофагов после однократной инъекции циклофосфана в дозе 250 мг/кг массы тела. Иммунотропное действие полифенольных соединений из сафлора красильного и календулы лекарственной превышает таковое у препарата сравнения – настойки эхинацеи пурпурной

Isolation of a wide range of minerals from a thermally treated plant: Equisetum arvense, a Mare’s tale

Silica is the second most abundant biomineral being exceeded in nature only by biogenic CaCO3. Many land plants (such as rice, cereals, cucumber, etc.) deposit silica in significant amounts to reinforce their tissues and as a systematic response to pathogen attack. One of the most ancient species of living vascular plants, Equisetum arvense is also able to take up and accumulate silica in all parts of the plant. Numerous methods have been developed for elimination of the organic material and/or metal ions present in plant material to isolate biogenic silica. However, depending on the chemical and/or physical treatment applied to branch or stem from Equisetum arvense; other mineral forms such glass-type materials (i.e. CaSiO3), salts (i.e. KCl) or luminescent materials can also be isolated from the plant material. In the current contribution, we show the chemical and/or thermal routes that lead to the formation of a number of different mineral types in addition to biogenic silica
