В статье приведены результаты исследования процессов получения оксида магния путем разложения серпентинитов Арватенского месторождения серной кислотой и с добавкой азотной кислоты в раствор серной кислоты последуюшим разделением кремнезема из суспензии, нейтрализацией фильтрата аммиаком до значения рН 8,5 для осаждения и раздаеления ионов примесных металлов, осаждение и разделения ионов магния из раствора с использованием аммиака и углекислого аммония, термическое разложение корбаната магния с получением оксида магния. Установлено, что использования смесь кислот т.е. с добавкой небольшой количества азотной кислоты в раствор серной кислоты увеличиваеть выход оксид магния от 83,34% до 92,68 % чем при использования только серной кислоты при одинрковых нормах. При оптимальных условиях после термического разложения карбоната магния получен продукт содержащый 97,13% оксид магния со степенью извлечения 92,68 % от исходного сырья.
Trinatrium salt of glycyrrhizic acid (Glycytrinate) with strong anti-ulcerous activity combined with anti-inflammatory effect was synthesized on the basis of glycyrrhizic acid. According to the parameters of acute toxicity in experiments on white mice and rats with per oral administration Glycytrinate was included to the group of little toxic substances. And according to the assessment of anti-ulcerous activity on the models of rats’ gastric mucous membrane destruction caused by indo metasin, ortophen, and reserpin glycytrinate has an expressed antiulcer effect. The mechanism of glycytrinate’s antiulcer effect is linked with its antioxidant property and suppression of the secretory function of gastric glands.
Despite advances in medical science and prevention, cardiovascular pathology remains the leading cause of morbidity and mortality in economically developed countries. Acetylsalicylic acid (ASA) is currently the most widely prescribed and most proven base drug for oral antiaggregant therapy in cardiovascular disease. Despite the widespread use of acetylsalicylic acid to prevent cardiovascular complications in patients with ischemic heart disease (IHD) ischemic events also occur in a certain proportion of patients receiving regular antithrombotic therapy, which is associated with stagnation of ASA, that is seen as a manifestation of resistance. The problem of resistance to antiplatelet drugs is fundamental in its importance, as it lays the groundwork for the individualization of preventive therapy and the formation of more effective methods of disease prevention. This article discusses the problems that arise in the antiaggregant and anti-inflammatory effect of acetylsalicylic acid in the use of ischemic heart disease.
The aim of study was to research the effect of darmonal and phytin compounds on the amount of glycogen and lactic acid in the liver tissues.
Materials and methods. The new compounds of phytin-C were studied: phytin-C, cobalt phytate and patent substance of darmonal obtained from wheat grain cells grown under special conditions. For comparison, the bioflavonoid of plant origin Liv-52, being used in treatment of liver diseases, was also studied. The study was carried out on 60 white rats weighing 120-150 g. The toxic hepatitis was caused by subcutaneous administration of 50% carbon tetrachlormetan oil solution in dose 0.8 ml/100 g for 4 days.
Results. The results showed that the combined introduction of extract significantly enlarged the outcome at joint use drug Liv-52 in animals, and, especially such effect was noticeable with addition phytin-C. The use bioactive substance in combination with complex phytin compound was more effective for accumulation of glycogen in the liver than using the drugs separately, hepatotoxin - carbon tetrachlormetan reduced carbohydrate metabolism and led to increase glycogen in liver tissues as well as the decreased lactic acid. It was determined that the combined treatment was more effective at toxic hepatitis induced by carbon tetrachlormetan, it had the hepatoprotective effect and improved liver function.
