The effects of a transient doe-litter separation on plasma prolactin, FSH and oestradiol concentrations, as well as the effect on LH response to exogenous GnRH administered at the time of artificial insemination, were determined in nursing rabbits. The effects on fertility, and litter size after parturition, as well as litter survival after doe-litter separation, were also studied. Control does (n = 12) had free access to nursing, whereas biostimulated does (n = 12) were separated from their litters for 48 h before artificial insemination. Plasma prolactin concentrations were decreased 24 h after the doe-litter separation (P < 0.05). The response of prolactin to suckling reached 10 times the basal values measured on day 10 after parturition (P < 0.0001). Increased oestradiol concentrations were found during the 48 h after the doe-litter separation: at 0 h, before artificial insemination (P< 0. 0001), 1.0-2.0 h after artificial insemination (P < 0.001), at 2.5 h (P < 0.05), 3.0 h (P < 0.01), and at 3.5 h (P < 0.05) after artificial insemination. Exogenous GnRH administered at the time of artificial insemination caused a greater LH response in does previously separated from their litters during 48 h (P < 0.01). The transient doe-litter separation did not affect plasma FSH concentrations, fertility, litter size or litter survival. These results suggest that a transient separation of nursing does from their litters before artificial insemination results in a decrease in plasma prolactin concentrations that could promote growth of follicular waves, and high steroidogenesis activity, leading to increased oestradiol concentrations and inducing higher sensitivity of the pituitary gland to exogenous GnRH. These findings associated to the absence of suckling episodes would lead to higher LH response and, therefore, exert a major effect on fertility.

The study of law focuses, among other aspects, on important issues relating to equality, fairness and justice in as far as free access to information and knowledgeis concerned. The launching of the Open Access to Law Movement in 1992, the promulgation of the Durham Statement on Open Access to Legal Scholarshipin 2009, and the formation of national and regional Legal Information Institutes (LIIs) should serve as an indication of how well the legal world is committed to freely publishing and distributing legal information and knowledge through the Internet to legal practitioners, legal scholars and the public at large aroundthe world. In order to establish the amount of legal scholarly content which is accessible through open access publishing innovations and initiatives, this studyanalysed the contents of websites for selected open access resources on the Internet internationally and in South Africa. The results of the study showed that there has been a steady developing trend towards the adoption of open access for legal scholarly literature internationally, while in South Africa legal scholarly literature is under the control of commercial publishers. This should be an issue for the legal scholarship which, among its focus, is to impart knowledge about the right of access to information and knowledge.

В условиях непрерывного воздействия неблагоприятных факторов окружающей и производственной среды на человека особую актуальность приобретает изучение механизмов, поддерживающих гомеостаз организма. Длительное поступление фторидов в организм приводит к формированию хронической фтористой интоксикации, патогенез которой вызывает многочисленные споры и дискуссии. До сих пор недостаточно внимания уделяется изучению висцеральной патологии, обусловленной нарушениями иммунного статуса в условиях воздействия на организм соединений фтора. Практически отсутствуют исследования по изучению иммунной реактивности, определяющей морфофункциональный характер ответной реакции печени на ранних стадиях развития фтористой интоксикации. Цель работы - изучение действий патофизиологических механизмов иммунной реактивности печени при субхроническом действии на организм соединений фтора. Методика. Опыты проведены на 210 лабораторных крысах-самцах массой 180-220 г., разделенных на 2 группы: контрольную (n=80) и группу животных с субхроническим действием фторида натрия (n=130). Экспериментальные животные в течение 12 нед имели свободный доступ к водному раствору фторида натрия (концентрация 10 мг/л, что составляет суточную дозу фтора 1,2 мг/кг массы тела). Для изучения иммунологических и биохимических показателей забирали кровь из хвостовой вены через 1, 3, 6, 9, 12 нед от начала эксперимента. Для оценки состояния гуморального звена иммунитета определяли уровень сывороточных иммуноглобулинов (IgA, IgG, IgM) иммуноферментным анализом с помощью наборов реактивов ЗАО «Вектор-Бест» (Новосибирск). Уровень сывороточных цитокинов: TNF-α, IL-1β, 2, 4, 6, 10 определяли на анализаторе Multiskan EX методом иммуноферментного анализа с использованием наборов «Вектор Бест» (Новосибирск). Подсчет общего количества лейкоцитов произведен классическим способом в камере Горяева, анализ лейкоцитарной формулы - в окрашенных мазках периферической крови. Метаболические изменения оценивали по активности ферментов в ткани печени: щелочной фосфатазы (ЩФ), аланин- и аспартатаминотрансфераз (АЛТ, АСТ), лактатдегидрогеназы (ЛДГ), гаммаглутамилтранспептидазы (γ-ГТ). Активность ферментов определяли унифицированными методами с помощью наборов реактивов ЗАО «Вектор-Бест» (Новосибирск) на фотометре PM-750 (Германия). Гистологические исследования печени осуществляли после декапитации крыс, проводимой под эфирным наркозом. Результаты. Показано, что субхроническое воздействие фторида натрия сопровождается формированием внутриклеточных и внутрисосудистых повреждений печени. Активация медиаторов воспаления и развитие иммунологических нарушений в динамике эксперимента способствуют формированию системной воспалительной реакции, которая приводит к появлению стойких морфологических нарушений в печени и изменению активности ферментов основных метаболических путей. Заключение. Полученные результаты могут быть использованы при разработке и проведении профилактических мероприятий в условиях воздействия на организм высоких концентраций фтора с последовательным применением детоксикационной, иммуномодуляторной и органопротекторной коррекции. Studying mechanisms, which maintain the body homeostasis, is particularly important in the conditions of continuous impact of adverse environmental and manufacturing factors. Long-term exposure to fluorides leads to chronic fluoric intoxication, the pathogenesis of which is a subject of multiple controversy and discussions. Not enough attention is still paid to elucidating the visceral pathology associated with fluorine-induced immune disorders. There are virtually no studies of immune reactions that define the morphofunctional nature of the liver response to early stages of fluoric intoxication. Aim. To study pathophysiological mechanisms of hepatic immune reactivity in subchronic exposure of the body to fluorine compounds. Methods. Experiments were performed on 210 male rats weighing 180-220 g. The animals were divided into two groups: 1) control (n=80) and 2) subchronic exposure to sodium fluoride (n=130). The rats had free access to a 10 mg/l aqueous solution of sodium fluoride (daily dose, 1.2 mg/kg body weight) for 12 weeks. Blood was withdrawn from the caudal vein at 1, 3, 6, 9, and 12 weeks of the experiment for immunological and biochemical tests. Histological study of the liver was performed after decapitation of rats under ether anesthesia. Results. The subchronic exposure to sodium fluoride was associated with intracellular and intravascular damage of the liver. Activation of inflammatory mediators and development of immunological disorders during the experiment contributed to a systemic inflammatory reaction, which resulted in persistent morphological injuries of the liver and changes in enzyme activities in major metabolic pathways. Conclusion. The study results can be used for development and implementation of preventive measures against the effects of high fluorine concentrations, which would include a successive use of detoxification, immunomodulation and organ protection.

A forest owner can only commercialize non-wood products and services within a tightly restricted market niche. On account of free access being permitted to the forest it is impossible to deny to third parties the consumption of many non-wood products and services: everybody has the right to be in the forest for recreation. As a result many non-wood services cannot be commercialized by the forest owner, or not exclusively. What would seem unthinkable elsewhere on private property seems to be taken for granted in the forest: third parties may take products from the forest and even sell them without being the forest owners. For certain nonwood services or products, such as the installation of rope parks or for burial in the forest, the organizer must conclude an agreement with the forest owner or draw up a contract for servitude or benefit. In addition, for these activities a permit from the Forestry Department is necessary. On the other hand, for an itinerant school class or for the production of forest honey neither a binding regulation with the forest owner nor a permit from the Forestry service is necessary, provided that no constructions are erected in the forest. The only exclusive right which remains to the forest owner, besides the sale of his property, is the exploitation of his trees within the legal framework.

The article is devoted to the issues of informatization of health care in the context of medical reform in Ukraine. It was emphasized that the service component of health care reform should open free access to information for patients, in connection with which the eHealth system (electronic health care system) is being introduced in Ukraine. eHealth provides the exchange of medical information and the implementation of the program of medical guarantees of the population. It is substantiated that in order to effectively implement the state information policy in the medical field it is necessary to develop and adopt a legal act at the level of law, for example, the Law of Ukraine “On the functioning of the electronic health care system in Ukraine”. The task of such an act should be to determine the subjects of information policy in this area, the powers of individual bodies and non-governmental organizations or economic entities involved in the development and operation of electronic health care system. An important element of regulation should be to address the issue of cybersecurity when using eHealth and to determine the responsibility of specific entities for possible violations or threats to the system. It is determined that eHealth should cover all areas of medical services, including “military” and “departmental medicine”. It is emphasized that an important element of the reliable functioning of eHealth should be the training of medical staff to work with databases. At the same time, the provision on the possibility of providing “cloud” services related to the functioning of the electronic health care system should be taken into account during the creation of the draft law “On cloud services”. The possibility of using “cloud” storage of medical data and requirements for the use of “cloud” information services provided from territories of a jurisdiction other than the national one requires is assessment.
