The article attempts to analyse the historical event that was the process of normalisation of Ukrainian-Polish relations in the mid-1930s. It analyses the rationale that led to the conclusion of a normalisation agreement in 1935 between the Ukrainian National Democratic Union (UNDO) - the most influential social representative in the Ukrainian community in the western territories of Ukraine at the time - and the Polish government represented by representatives of the Sanation. In addition, the reasons that favoured the normalisation policy are discussed. The conclusion of the agreement was a landmark step. In exchange for a declaration of loyalty and the UNDO's recognition of the Polish raison d'état, the government was to implement many Ukrainian demands. For the UNDO, it was an opportunity to create parliamentary representation and ensure that Ukrainian NGOs were able to function, while for the Sanation, it was a chance to gain a political ally among Ukrainians in the region and the Polish parliament. In this way, the civic equality of Ukrainians was marked. At the same time, convergence of views on many issues was emphasised, but also issues that should be resolved and put in order were pointed out.

The article analyzes the evolution of Iranian-Syrian relations and describes their features. Iran and Syria are historically, politically and geographically related states, diplomatic relations between which were established in 1946. However, after the Islamic Revolution, in 1979 and the leadership of A. Khomeini, relations between the countries strengthened and began to develop rapidly. Because Syria was the first Arab country to diplomatically recognize the Islamic Republic of Iran and actively support Iran during the Iran-Iraq war of 1980-1988. It is worth to say that these two countries combine many factors, especially such as common interests and position on current regional issues and the presence of shared enemies. Оfficial Damascus and official Tehran consider themselves as part of the Middle East's "axis of resistance" of the defense alliance, thus responding to joint threats from Israel and the United States. The position and role of Iran in the civil war in Syria are highlighted. In fact, since the beginning of the Syrian crisis, Iran has provided political, economic and military support to Assad, and has since become a major player in the Syrian conflict. In the current context, Iranian leaders have described Syrian President Al-Assad as his main ally and are working hard to keep him in power. According to a study published by the Office of the US Special Envoy to Syria Staffan de Mistura, financial, military and economic assistance to Iran in Syria is estimated at about $ 6 billion USA per year. It is also investigated that Syria fully shares and supports the foreign policy of official Tehran and the active development of nuclear and missile programs. Syria strongly condemns the decision of former US President D. Trump to withdraw from the JCPOA and is in full solidarity with the leadership, government and people of Iran.

The aim: to consider the existing methods of diagnosis, clinical course and treatment of most common malignant tumors of soft tissues of maxillofacial area and oral cavity. Materials and methods. Method of economical analysis, method of system analysis, medical – statistical method, mathematical modeling method, information-analytical method. Results. Types and clinic of the most widespread tumors of the specified area are considered. The technique of examination at the specified pathology with use of auxiliary methods of diagnostics is described. The main methods of special treatment of cancer patients are mentioned. The clinical course of four stages of maxillofacial cancer was analyzed on the example of lip cancer. It is confirmed that morphological methods are the most informative of all currently available diagnostic tools and their brief description is given. Conclusions. Early diagnosis of malignant neoplasms, timely recognition and treatment of precancerous conditions against which cancer develops, is the main task of a general practitioner for the prevention of cancer. The dentist at the stage of planned rehabilitation of the oral cavity should pay attention to all changes in the mucous membrane. The formation of high-risk cancer groups and their in-depth examination can increase and detect precancerous diseases and malignant neoplasms in the early stages, which can serve as a real basis for the prevention of cancer of the maxillofacial region, oral mucosa, tongue and lips.
