In the pathogenesis of various diseases histamine performs an important role relating to one of the most important mediators involved in the regulation of vital functions in the body. Histamine plays a key role in the development of allergic diseases and pseudoallergic reactions. Therefore, in clinical practice, of particular interest are drugs that block the effects of histamine - antihistamines. The lecture highlights mechanisms of action of histamine and indications for antihistamines. Particular attention is given to parenteral forms of antihistamines and benefits of a new form of antihistamines for parenteral use without sedation - fenkarol one of quinuclidine derivatives. Features and advantages of antihistamines - quinuclidine derivatives, first developed in Laboratory of academician M.D. Mashkovsky are presented.

Metals have been used in clinical practice for hundreds of years and for a variety of indications. Although potent agents whose activity may be adapted by manipulation of their chemistry and that of associated ligands, their use has been limited by toxic effects. There is now a burgeoning series of delivery technologies available which may be adapted to the administration of metal based drugs. Together with greater understanding of metal chemistry and their mechanisms of action in disease processes, there is an opportunity to increase the use of metals in medicine by targeting their action more effectively to the therapeutic site and/or protecting the body from toxic effects.

The article deals with the life path and research activities of the founder of resuscitation science (intensive care) Vladimir A. Negovsky. He was born in 1909 in the city of Kozelets, Ukraine. After graduating from university in 1933, Negovsky worked as a researcher in the pathophysiological laboratory of the Central Institute of Hematology and Blood Transfusion in Moscow, where he worked for about a year with Professor S.S. Bryuchonenko, the creator of one of the world’s first heart-lung apparatus and where, apparently, his scientific interests were finally formed. In 1936, Negovsky wrote a letter to the Prime Minister of the USSR V.M. Molotov, in which he substantiated the prospects and importance of research in the field of cardiopulmonary resuscitation and asked for help in creating a research laboratory on this problem. Surprisingly, his request was granted — in the same year an order was issued on the organization of a special-purpose laboratory on the problem: ‘Restoration of life processes in phenomena similar to death”. Such a scientific research laboratory was created for the first time in the world. V.A. Negovsky and his collaborators modified the resuscitation method proposed by F.A. Andreev (1879–1952) and included the injection of Ringer-Locke’s solution with adrenaline into the carotid artery towards the heart (centripetally, i.e. against the blood flow). This method was improved by Negovsky and the Laboratory staff by using the radial and brachial arteries as an access for centripetal blood injection, which made it possible to simplify the technique for use in clinical practice and was supplemented by artificial lung ventilation by forced air injection into the lungs with bellows, as they have shown that intra-arterial pumping alone without mechanical ventilation is often ineffective. In the years before the attack of Nazi Germany on the USSR (1938–1941), V.A. Negovsky and his colleagues carried out a series of experimental studies devoted to the resuscitation of animals with lethal blood loss, as well as to the problem of extinction and restoration of brain functions, the results of which were published in several articles. In 1942, V.A. Negovsky defended his PhD on the topic “The relationship of respiration and blood circulation in the process of dying of animals from blood loss and in the subsequent period of restoration of vital functions”. During World War II, Negovsky organized a front-line medical teams, with which he went to the front line and where, in 1943, the developed complex of resuscitation measures was first used for wounded soldiers. In his dissertation on medicine “Restoration of vital functions of an organism in a state of agony or a period of clinical death” defended in 1943, he outlined the main provisions of the pathophysiology of terminal states and the principles of a complex method of resuscitation; the dissertation was published in a book in the same year. In 1945–1946, V.A. Negovsky publishes reports in the journals “JAMA” and “Nature” about the clinical experience of using the developed method of cardiopulmonary resuscitation and the importance of developing this problem of medicine, thus providing a priority in creating a new scientific direction. In 1946, using the experience gained in the war, the Laboratory staff continued their clinical work, starting to provide medical care to dying patients at the Institute of Thoracic Surgery of the USSR of the Academy of Medical Sciences, thus creating their own clinical resuscitation unit. In 1947, V.A. Negovsky was awarded the title of professor. Despite the successes achieved, Negovsky and his colleagues had to overcome stubborn misunderstanding and expressed resistance from many representatives of the medical community. An interesting fact in the biography of V.A. Negovsky was his participation in 1953 in the CPR (chest compression and administration of pharmacological drugs) of Joseph Stalin. In 1952, the Laboratory team created the first instruction, which was published by the USSR Ministry of Health for use in clinical practice “On the introduction into medical practice of methods for restoring the vital functions of an organism in a state of agony or clinical death”, which was republished in 1955, 1959 and 1963 with the introduction of changes to the CPR algorithm. In 1959, on the initiative of V. \A. Negovsky, the first prototype of the intensive care unit in the USSR was organized, which was named “Center for the Treatment of Shock and Terminal States”. In 1961, he reported about creating a new medical science — resuscitation science, the subject of which is nonspecific general pathological reactions of the body, pathogenesis, therapy, and prevention of terminal states, life support in critical states. In 1972, in the first issue of the newly created journal “Resuscitation”, V.A. Negovsky published an article “The second step in resuscitation — the treatment of the ‘post-resuscitation’ disease”, in which he outlines the pathophysiological mechanisms of the development of post-resuscitation changes in the body. A special topic is overcoming the “iron curtain” and acquaintance of V.A. Negovsky with the American founder of the first Intensive Care Units (ICU) P. Safar, who laid the foundation for many years of scientific interaction and personal friendship. In 1985, on the basis of the Laboratory, Negovsky organized the Research Institute of General Reanimatology of the USSR of the Academy of Medical Sciences, which now bears his name. Vladimir Negovsky loved classical music, especially I.S. Bach, painting — Sandro Botticelli, Francisco Goya, always found time and energy for skiing. He died on August 2, 2003, and is buried in Moscow.

Iron is an assential element for the growth, division, differentiation and functioning of any cell in the body. Iron is virtually important for human and danger at the same time, because with excessive accumulation it causes oxidative stress with formation of highly active oxygen radicals and reactive form of nitrogen that can destroy cell membranes, proteins, nucleic acids, reduce cell viability, with, according to modern concepts, can contribute to the development of many diseases (cardiovascular, rheumatic, gastrointestinal, neurodegenerative, oncological, metabolic and others), and also accelerate the aging process. Part 1 of this review discussed the issues of iron metabolism in human, including its regulation at the cellular and systemic levels, the intake, transport, use, accumulation and export of iron in cells, the role of the labile iron pool in the cytoplasm of cells and plasma non-transferrin bound iron. Data are provided on the causes, frequency and significance of iron overload in the formation of free radicals and the development of oxidative stress. Part 2 of the review provides information on diseases associated with iron overload as well as information on ferroptosis - a new type of iron-dependent regulated cell death. Attention is paid to the works of domestic authors, where it was found that prolonged use of drinking water with a high iron content is unfavorable for the population and leads to an increase in the overall incidence, the development of the diseases of the blood, skin and subcutaneous tissue, musculoskeletal system, digestive system, urogenital system, and allergic diseases. Separate publications are cited on the possibility of a negative effect of iron at concentrations in water of 0.3 mg/l and lower. The material of the review emphasizes the preventive significance of caution attitude to regulating iron in the water in the Russian Federation, where 1/3 of the population uses iron-containing water for drinking, and substantiate the feasibility of establishing a hygienic limit for iron in water not higher than 0.3 mg/l.

Introduction. Lipids are a widespread group of biologically active substances in nature, making up the bulk of the organic substances of all living organisms. They accumulate in plants in seeds, as well as in fruits and perform a number of vital functions: they are the main components of cell membranes and the energy reserve for the body.Aim. Study of neutral lipids of sown oats (Avena sativa L.).Materials and methods. The objects of the study were fruits (grains) of oats of the sown variety "Tashkent 1," harvested in the Republic of Uzbekistan. Results and discussions. Neutral lipids of oat grains have been found to contain 13 fatty acids with a predominance of the sum of oleic, linolenic and linoleic acids. The total degree of unsaturation was almost 78%. Absorption bands characteristic of these substances were observed in the IR spectrum of MEGC.Conclusion. According to the results of the NL analysis, oat grains consisted of triacylglycerides and free LCDs, which were accompanied by hydrocarbons, phytosterols, triterpenoids and tocopherols.

The “disconnect” between the body of knowledge acquired in classroom settings and the application of this knowledge in clinical practice is one of the main reasons for professional fear, anxiety and feelings of incompetence among freshly graduated nurses. While the phenomenon of the theory-to-practice gap has been researched quite extensively in high-income country settings much less is known about nursing students’ experiences in a developing country context. To rectify this shortcoming, the qualitative study investigated the experiences of nursing students in their attempt to apply what they learn in classrooms in clinical learning contexts in seven sites in Nigeria. Thematic content analysis was used to analyse data gained from eight focus group discussions (n = 80) with the students. The findings reveal a multifaceted theory-practice gap which plays out along four tensions: (1) procedural, i.e. the difference between practices from education institutions and the ones enacted in clinical wards – and contradictions that emerge even within one clinical setting; (2) political, i.e. conflicts that arise between students and clinical staff, especially personnel with a lower qualification profile than the degree that students pursue; (3) material, i.e. the disconnect between contemporary instruments and equipment available in schools and the lack thereof in clinical settings; and (4) temporal, i.e. restricted opportunities for supervised practice owing to time constraints in clinical settings in which education tends to be undervalued. Many of these aspects are linked to and aggravated by infrastructural limitations, which are typical for the setting of a developing country. Nursing students need to be prepared regarding how to deal with the identified procedural, political, material and temporal tensions before and while being immersed in clinical practice, and, in so doing, they need to be supported by educationally better qualified clinical staff.

Various types of conditions exist in the body that causes fever and pain. Drugs that are used to treat fever are called antipyretics, and those are usually prescribed to treat elevated body temperature. But those drugs result in many other side effects like ulcers, perforations, bleedings and obstructions, which make their use questionable and limiting. Medicinal plants are used in the treatment of diseases from the starting of the human race and the process; they had been subjected to rigorous investigations and tests to establish a scientific proof and validation of the various pharmacological activities and their respective mechanisms of action in treating the herbs. Considering the anti-inflammatory properties of the plant, Xylocarpus mekongesis was investigated for its antipyretic activity in yeast method and 3doses out of which 00mg/kg body weight showed a better activity compared to the standard drug and other extracts too. The mechanism of action was similar to the paracetamol action that is inhibition of prostaglandin synthesis.

Cirrhosis of liver is one of the common medical problem in daily clinical practice and one of the leading causes of morbidity and mortality. Zinc is an essential trace elements for human and plays in many biological roles in the body. Among them, zinc deficiency is thought to be involved in metabolism of ammonia and causes hyperammonia that worsen hepatic encephalopathy. This study aimed to find out the severity of cirrhosis of liver was by Child Turcotte Pugh score and to investigate the associations between serum zinc level and severity of cirrhosis. A hospital-based cross-sectional descriptive study was performed on 78 patients with different underlying causes of cirrhosis of liver at the Medical Units of Yangon General Hospital and Yangon Specialty Hospital. Among the study population, Child grade A was found to be 28.21%, Child grade B was 30.77% and Child grade C was 41.03%. Regarding result of serum zinc level, 62.8% were low level, 28.2% were within normal level and 8.9% were high level. Mean value of serum zinc level in grade A was 0.68 mg/l, grade B was 0.54 mg/l and grade C was 0.48 mg/l (p=0.00). It was found out that there was a high prevalence of zinc deficiency in severe cirrhotic patients. The zinc level was significantly lowest among patients with Child-Pugh C as compare to those with Child-Pugh B and C. Severity of zinc deficiency should be requested for supplementation therapy in cirrhotic patients as to prevent complications such as hepatic encephalopathy, hepatocellular carcinoma and liver failure. Screening for zinc deficiency may need in these patients with more advanced cirrhosis because it seems to be a marker of advanced liver disease and it can be deducted that awareness of serum zinc level among cirrhotic patients is very important in clinical practice.

Skin is a protective organ and the largest of the human body. Due to its pivotal role in aesthetic appearance, skin health has a significant impact on quality of life. Chronic inflammation of the skin often marks the beginning of various skin diseases. Immune-mediated responses serve to protect the body from external insults and require succinct control, and can lead to ongoing cellular damage and various skin conditions if left unchecked. Studies have shown that phytochemicals can alter processes involved in skin inflammation and alleviate the effects of aging, cancer, atopic dermatitis, psoriasis, and vitiligo. Direct molecular targets of some phytochemicals have been identified and their precise mechanisms of action investigated. In this review, we summarize recent findings on the effects of phytochemicals on skin inflammation and the mechanisms of action involved.
