Biological reclamation by plants with nitrogen-fixing symbionts and enriching the soil with organic substances is an urgent problem for the Republic of Mari El, where sod -podzolic loam, sandy loam and sandy soils with low organic content, nitrogen and other important elements was expanded. The feasibility of establishing a pine culture with the introduction of soil-improving plants was noted by many researchers, but their impact on the effectiveness of silvicultural properties of the soil, physiological processes and growth are poorly understood. In this paper we evaluated the influence of soil reclamation plants on silvicultural properties of soils, the intensity of the basic physiological processes and growth index of Scots pine. According to research, the perspective and cost-effective measure for improving the fertility of poor sandy coniferous soil, improving resilience and productivity of pine plantations is the introduction of the common juniper and soil reclamation plants with nitrogen-fixing symbionts, such as Russian broom, perennial lupine. When choosing the plants we should recognize its water regime. At the conditions of sufficient moisture it is suitably administered to the cultures of Scots pine, common juniper and perennial lupine. In the dry forest conditions the most effective is an introduction the culture of Scots pine, Russian broom. At the same time, the porosity of the soil increases from 47 to 52% and the content of humus and nitrogen by rises to18-20%.
48 women at the age of 26,5±3,8 with the benign tumors of the mammary glands (fibroadenomas) were operated by means of vacuum aspiration with the En‐cor apparatus (made in the USA) under the ultrasound control. The tactics of the surgery satisfied the requirements (standards) accepted in Russia. In the core group (II, 20 patients) low‐dose monophasic combination oral contraceptives with the ethinylastradicol as an active ingredient at a dose of 20 mcg were prescribed for six months beginning with the 1st day of the menstrual cycle (period) which followed the operation. In the group of comparison (22 patients) the hormone‐therapy during the post‐operative period wasn’t carried out. The observing time after the operation lasted in average two and a half years (the maximal duration was 3,2 years, the minimal one – 2,1 years). For the two check points the date of the access and the sixth month after the adenomammectomy were chosen. During this time the laboratory, breast ultrasound and the clinical forms of control of the condition of the mammary gland and of the hormonal background were carried out. The investigation revealed the normalization of the background of the female and the male sex hormones after the adenomammectomy by means of the aspiration method. It was characteristic for the women to whom the hormone‐therapy after the adenomammectomy was prescribed that the changes with them were maximal. Apart from the normalization of the general hormonal background of these women there were also some signs of a significant reduction in the risk of recurrence and the development of new fibroadenoma of breast.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
