All of these centuries-old records contain enormous treasures, and the modern medicine is increasingly searching for the sources of natural remedies. The Franciscans should be credited for carefully collecting the methods folk treatment and passed them on to future generations. In the words of Br. Marko Karamatić: "The fact that the Friars were engaged in healthcare, that they became the first graduate doctors in Bosnia and Herzegovina, that they wrote" herbal manuals " and other medical records, is the result of historical opportunities in these areas, and this activity became one of the most important tasks for the Franciscans. They performed their duties regardless of the circumstances.

Introduction:Pharmacy and medicine belong to the oldest human activities, so the development of these sciences is closely related to the socio-economic, cultural and religious opportunities of the nations within which they have been developing.Goals:To present the historical influence of pharmacy on the development of the human being from its very beginning; To present the historical link between pharmaceutical and medical activity, as well as early development of independent pharmaceutical activity; To present the historical influence of pharmacists on the development of botany and pharmacognosy and to present the historical influence of the first written herbarium and incunabula on the development of pharmacognosy.Material and Methods:The article has a descriptive character, and represents a systematic review of the literature dealing with this topic.Results:The roots of pharmacy started to the very beginning of human civilization, when people collected various medicinal herbs and try to alleviate their health problems, pain and suffering. The scientific foundations of the pharmacy were set up in the antique period by the books of Dioskurides and Galen, and its further development continued in the mid-century, at the beginning by rewriting famous parts of ancient literature, and later by writing new discoveries (the base of this development was represented by South Italy) so that in 1240, for the first time in history, came the separation of doctors and pharmacists, and at the beginning of the 13th century the opening of the first pharmacy.Conclusion:The effort to maintain knowledge of medicinal herbs and its practical application has led to the writing of a large number of recipes books, the forerunners of today’s pharmacopeia, while the aspiration to classify medicinal herbs, and the desire to present medicinal herbs to ordinary people, has led to a large number of herbaria, making the knowledge and descriptions of plants available to many, not just the nobility. Descriptions of plants in herbaria and later in incunabula lead to the development of pharmacognosy, and to the opening of the first Department for pharmacognosy, 1545 in Padua.

The time interval from the 9th to the 13th century remained known as the “Golden period of the Arab science”, and a significant place among the taught sciences are occupied by Medicine and Pharmacy. In the history of medicine, Islamic medicine, also known as Arabic medicine, refers to the science of medicine developed in the Islamic Golden Age, and written in Arabic Arabs were able to use their cultural and natural resources and trade links to contribute to the strong development of pharmacy. After the collapse of the Arab rule, the Arab territorial expanses and cultural heritage were taken over by the Turks. Although scientific progress in the Turkish period slowed down due to numerous unfavorable political-economic and other circumstances, thanks to the Turks, Arab culture and useful Islamic principles expanded to the territory of our homeland of Bosnia and Herzegovina. Significant role in the transfer of Arabic medical and pharmaceutical knowledge was also attributed to the Sephardic Jews who, with their arrival, continued to perform their attar activities, which were largely based on Arab achievements. However, insufficiently elaborated, rich funds of oriental medical and pharmaceutical handwriting testify that Oriental science has nurtured in these areas as well, and that the Arab component in a specific way was intertwined with other cultures and traditions of Bosnia and Herzegovina.

A new class of antimicrobial agents, 3-nitrocoumarins and related compounds, has been chosen as a subject of the present study. In order to explore their activity and molecular properties that determine their antimicrobial effects, QSAR models have been proposed. Most of the 64 descriptors used for the development were extracted from semiempirical and density functional theory (DFT) founded calculations. For this study literature data containing results of microbiological activity screening of 33 coumarin derivatives against selected clinical isolates of C. albicans (CA) and S. aureus (SA) have been selected. Multivariate predictive models based on random forests (RF) and two hybrid classification approaches, genetic algorithms (GA) associated with either support vector machines (SVM) or k nearest neighbor (kNN), have been used for establishment of QSARs. An applied feature selection approach enabled two-dimensional linear separation of active and inactive compounds, which was a necessary tool for rational candidate design and descriptor relevance interpretation. Candidate molecules were checked by cross-validated models, and selected derivatives have been synthesized. Their antimicrobial activities were compared to antimicrobial activities of the representative derivatives from the original set in terms of minimal inhibitory concentration (MIC) against chosen SA and CA ATCC strains. High ranking of descriptors consistent with the degree of hydrolytic instability of selected compounds is common to models of antimicrobial activity against both microorganisms. However, descriptor ranking indicates different antimicrobial mechanisms of action of chosen coumarin derivatives against selected microbial species.

The Arab cultural heritage was an era of invaluable preservation and development of numerous teachings, including biomedical sciences. The golden period of Arab medicine deserves special attention in the history of medicine and pharmacy, as it was the period of rapid translation of works from Greek and Persian cultures into Arabic. They preserved their culture, and science from decay, and then adopted them to continue building their science on theirs as a basis. After the fall of Arabian Caliphate, Arabian pharmacy, continued to persevere, and spread through Turkish Caliphate until its fall in the First World War. That way, Arabian pharmacy will be spread to new areas that had benefited from it, including the area of occupied Bosnia and Herzegovina. Because of the vast territorial scope of the Ottoman Empire, the focus of this paper is description of developing pharmacy in Bosnia and Herzegovina during the time of Ottoman reign.

The main objective of this study was to determine levels of certain persistent organic pollutants (POPs) in Neretva River, Bosnia and Herzegovina (BiH), which is currently facing implementation of the Stockholm Convention on persistent organic pollutants (POPs) and environmental protection strategies. This is the very first report on the deployment of semipermeable membrane devices (SPMDs) in BiH. SPMDs were used for continuous 3-weeks sampling of POPs at three locations, covering 220 km long stream of the Neretva River. Water concentrations of polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs) and polybrominated diphenylethers (PBDEs) were calculated using performance reference compounds (PRCs). The total OCP concentrations ranged from 40 to 140 pg L(-1) and most of compounds were detected only in lower course of the river. Total PAH ranged from 160 to 4000 pg L(-1) and show a clear spatial variation. Dominant PAHs were phenanthrene, fluoranthene, fluorene and acenaphthene. Total PCB ranged from undetectable to 120 pg L(-1). From the group of 15 PBDE congeners investigated, only PBDE-47 and PBDE-99 were detected. Since the concentrations of broad spectrum of POPs found in the Neretva River are quite low, future actions should be focused on preservation rather than on sanitation measures. Regular monitoring should anyhow be established.
