Nature, as well as the human body, contains an abundant quantity of organic molecules. This textbook describes selected oxygen, sulfur, nitrogen derivatives of hydrocarbons, heterocyclic compounds of their reactions, which are important in the human body or are found in pharmaceutical active substances, poisons, foodstuffs and heat-treated food. The last part of the textbook describes the isomerism of organic compounds, which enables dynamic changes in the structure of molecules that have different properties. Nature is filled with different plants and animals and is the first laboratory to produce bioactive organic natural compounds. These compounds are compatible with human cells and are applicable as therapeutic medicine. There is an effort to reproduce natural molecules in chemical laboratories, but they cannot be as perfect as the natural ones. Synthetic molecules can serve as a model for multiple studies, but there still does not exist a magic panacea pill or a perfect copy of nature, for the treatment of various diseases. Knowledge about the regenerative and toxic effect of medicinal substances in dependence on their structure (type and number of substituents) is very important for the understanding of their role in modulation of health and disease in dependence on their concentration. Compounds can be used daily only in recommended doses (higher doses can be toxic), but still will not replace a healthy diet. People need a varied diet to be healthy, in which are all necessary nutrients, what Hippocrates demonstrated long ago “Let food be the medicine, and let medicine be the food.” This book is written for students who select bioorganic chemistry subject during the study of general medicine or dentistry as well as for motivated students who would like to practice their knowledge and wish to improve in this subject and for students who would like to learn simplified basic organic reactions with their future application in biochemistry. Learn the simple models mainly through creative simple instruction by using different colours, by repetition, practice by drawing of formulas by hand (at least three times) and memorization of common names of compounds and their reactions which have application in biochemistry. Thus, establishing simple educational methods how to distinguish organic molecules according to the colours of a functional group can promote universal learning for all students who thought that chemistry is a difficult subject, but hopefully they change their opinion after study of this book.

Keywords: organic molecules, oxygen, sulfur, nitrogen derivatives of hydrocarbons, heterocyclic compounds, chemical reactions, isomerism of organic compounds

The peer-reviewed textbook and microscopic atlas is aimed at understanding the basic microscopic structure of cells and tissues in a light microscope. Texts in the textbook are complemented by a rich set of histologic micrographs with basic and specific staining techniques.

All histologic micrographs were prepared by the author's team at the Department of Histology and Embryology, Faculty of Medicine, UPJŠ.

University scripts “Visceral pathology of vascular origin“analyze one of the most challenging vascular regions, the aorta and the visceral aortic branches, from the surgical perspective. The diagnostic and the treatment aneurysms of the abdominal aorta are dedicated to the first chapter. Early diagnostic and operative treatment is crucial in the treatment of ruptured aneurysms of the abdominal aorta. Shortening of the interval between the patient’s arrival with ruptured aneurysm of the abdominal aorta into the hospital and the beginning of the operation decreased the perioperative mortality. This shortening, together with the use of the cell savers, led to the dropping of perioperative mortality from 50% to 20%. The diagnostics and surgical treatment of the acute and chronic occlusion of the aorta and iliac arteries are analyzed in the second chapter. In this chapter, the focus is given to the aortobifemoral bypass as “the gold standard“ of the surgical therapy of aortoiliac atherosclerosis. The management of acute mesenteric ischemia is the content of the third chapter. Acute mesenteric ischemia is a severe condition with high mortality. The problem of acute mesenterial ischemia is a delayed diagnostic that is the reason for poor therapeutical outcomes of the disease. The possible imagine studies and operations used in treating acute mesenteric ischemia are brought in this chapter. Chronic mesenteric ischemia leads to cachexia. The diagnosis of chronic mesenterial ischemia is one of the most demanding, and surgical therapy used in the treatment of chronic mesenterial ischemia also belongs to the most challenging operations. Left-sided colon ischemia belongs to the severe complications of the aortoiliac reconstructions. Left-sided colon ischemia has a high mortality. In the prevention of the left-sided colon, ischemia is preserving at least one internal iliac artery. The complex diagnostics treatment of intraabdominal compressive syndromes as Dunbar syndróme, „Nutcracker“ syndróme a Wilkie syndróme, analyzed in the last chapter.
