Growth and reproduction of Moina rectirostris (Leydig) and Ceriodaphnia quadrangula (O. F. Muller) with feeding on detritus. [Translation from: Sbornik po prudovomu rybovodstvu, 79-89. Moscow, VNIRO, 1969.]

The significance of detritus in the nutrition of aquatic animals, especially of the small representatives of the zooplankton, has been studied very slightly. Research so far has established that in M. rectirostris with feeding on protococcal and single-celled green algae and bacteria the beginning of formation of eggs takes place in 2 - 4 days. The young appear in 4 - 6 days. In this study M. rectirostris and C. quadrangula are fed on detritus of natural origin in laboratory conditions. In order to determine the assimilability and productive: effect of detritus, the author set up experiments, permitting to characterize the rate of growth, speed of maturing and fertility of M. rectirostris and C. quadrangula with feeding of them on detritus of different composition and age

Программированные роды у женщин с оперированной маткой

The paper deals with the problems of programmed delivery in women with a uterine scar. The study included 144 pregnant women with a uterus operated who started to give birth vaginally (per vias naturales). The conditions for induction, analyze the clinical efficacy of different methods of induction were assessed. 134 women given birth successfully, programmed delivery were conducted in 84 patients. There were 3 ruptures of the uterus.Статья посвящена проблемам программированных родов у женщин с «рубцом на матке». В исследовании участвовали 144 беременных с оперированной маткой, начавших рожать per vias naturales. Проведена оценка условий для родовозбуждения, проанализирована клиническая эффективность различных методов индукции родов. Успешно проведены влагалищные роды у 134 пациенток, у 84 — программированные роды. В группе программированных родов произошел один разрыв матки

Программированные роды при гестационном сахарном диабете: минимизация рисков — улучшение материнских и перинатальных исходов

Background. Modernity is characterized by an avalanche-like increase in the frequency of gestational diabetes mellitus (in 45 times over the past 20 years). The main tasks of the work in the risk strategy of gestational diabetes mellitus are: prediction of pregnancy complications and the searchingh for new technologies for their delivery. To date, there are still very controversial questions about the timing and methods of delivery of patients with gestational diabetes mellitus. Due to the high incidence of unfavourable perinatal outcomes in gestational diabetes mellitus, the percentage of cesarean sections in some countries reaches 60%, which leads to maternal morbidity and a decrease in the reproductive health of the population. Aims is to improve of maternal and neonatal outcomes based of the rational choice of delivery technology in gestational diabetes mellitus. Methods. A retrospective analysis of delivery methods was performed in 9769 patients with gestational diabetes mellitus at full-term gestation. Results. The developed and implemented programmed delivery technique was an alternative to cesarean sections, it allowed to reduce the frequency of abdominal delivery, while improving maternal and neonatal outcomes. The frequency of cesarean sections in programmed delivery was 2 times lower than in the presented facilities and significantly lower than in the population (10.010.7%). In the programmed delivery group there was a significant reducing morbidity of hypoglycemia in newborns compared to planned caesarean section by 2 times and respiratory distress syndrome by 2.5 times (p 0.05). The indices of cerebral status impairment, birth traumatism corresponded to physiological childbirth and did not exceed the average population. Conclusions. The method of programmed delivery presented in this paper was one of the reserves for reducing the frequency of cesarean sections and allowed to personalize delivery in respiratory distress syndrome.Обоснование. Современность характеризуется лавинообразным ростом частоты гестационного сахарного диабета (ГСД) (за последние 20 лет в 45 раз). Основными задачами работы в стратегии риска ГСД являются прогнозирование осложнений беременности и поиск новых технологий их родоразрешения. На сегодняшний день остаются весьма дискуссионными вопросы о сроках и методах родоразрешения пациенток с ГСД. В связи с высокой частотой неблагоприятных перинатальных исходов при ГСД доля кесаревых сечений в отдельных странах доходит до 60%, что приводит к материнской заболеваемости и снижению репродуктивого здоровья популяции. Цель исследования улучшение материнских и неонатальных исходов на основании рационального выбора технологии родоразрешения при ГСД. Методы. Был проведен ретроспективный анализ методов родоразрешения у 9769 пациенток с ГСД при доношенном сроке гестации. Результаты. Разработанная и внедренная методика программированных родов явилась альтернативой кесарева сечения, позволила снизить частоту абдоминального родоразрешения, при этом улучшая материнские и неонатальные исходы. Частота кесаревых сечений при программированных родах была в 2 раза ниже показателей по представленным учреждениям и значительно популяционных (10,010,7%). В группе программированных родов отмечено достоверное снижение (в 2 раза) заболеваемости новорожденных гипогликемией по сравнению с плановым кесаревым сечением и синдрома дыхательной недостаточности (в 2,5 раза, р 0,05), а показатели нарушения церебрального статуса, родового травматизма соответствовали физиологическим родам и не превышали среднепопуляционные. Заключение. Представленная в данной работе методика программированных родов явилась одним из резервов снижения частоты кесаревых сечений и позволила персонифицировать родоразрешение при ГСД
