<p>Uvod: Temperament predstavlja skup psiholo&scaron;kih osobina, to jest način, brzinu i jačinu umnog i emotivnog reagovanja svojstven pojedincu, odnosno njegovu narav, ćud, prirodu. Savremena istraživanja premorbidnog afektivnog tipa temperamenta, govore u prilog njegovog značaja u etiologiji i kliničkoj evaluaciji bolesti zavisnosti. Cilj: Utvrditi i uporediti temperament kod osoba obolelih od mentalnog poremećaja i poremećaja pona&scaron;anja zbog upotrebe opijata i zdrave populacije. Materijal i metode: Istraživanje je urađeno po tipu studije preseka, i obuhvatalo je 200 ispitanika, podeljenih u dve grupe. Ispitivanu grupu činilo je 100 stabilnih zavisnika od opijata na supstitucionoj terapiji metadonom, starosti od 18 do 40 godina, bez komorbidne bolesti iz kruga psihotičnih poremećaja. U kontrolnu grupu uvr&scaron;teno je 100 zdravih osoba &scaron;to sličnijih sociodemografskih karakteristika sa ispitivanom grupom. Njihov temperament je određivan TEMPS-A upitnikom samoprocene. Rezultati: Utvrđeno je statistički značajno če&scaron;će postojanje dominantog temperamenta kod zavisnika, kao i prisustvo depresivnog, ciklotimnog, razdražljivog i anksioznog temperamenta, koji govore u prilog osnovne razlike između zdrave populacije i populacije sa mentalnim poremećajem i poremećajem pona&scaron;anja zbog upotrebe opijata. Zaključak: Afektivni temperament, kao premorbidna karakteristika ličnosti, ima uticaja na nastanak i razvoj zavisnosti od opijata. Stoga je od značaja da se uzmu u obzir osobine hipertimnog temperamenta kao protektivnog ili depresivnog, ciklotimnog, radražljivog i anksioznog temperamenta kao rizičnih faktora u etiologiji, prevenciji i terapiji bolesti zavisnosti.</p> / <p>Introduction: Temperament is a set of psychological characteristics, ie the speed and strength of mind and emotional reactions peculiar to the individual, or his character, temperament, nature. Modern research of the premorbid affective temperament is in favor of its significance in the etiology and clinical evaluation of substance abuse. The Aim: To determine and compare the temperament of people suffering from mental and behavioral disorders due to use of opioids and healthy population. Materials and Methods: The study was cross-sectional, and 200 subjects were included and divided into two groups. The study group included stable opiate addicts on substitution therapy with methadone, aged 18 to 40 years, without co-morbid psychotic disorders. The Control group consisted of 100 healthy individuals with similar sociodemographic data as the Study group. Their temperament was determined with the TEMPS-A auto-questionnaire. Results: Statistical significance of a dominant temperament was more frequently found in the subjects with opioid dependence, as well as in depressive, cyclothymic, anxious and irritable temperament, which leads to the fundamental differences between a healthy population and a population with mental and behavioral disorders due to the use of opioids. Conclusion: Affective temperament, as a premorbid personality trait, has an impact on the occurence and development of opiate dependence. Therefore, it is essential to take into account the characteristics of a hyperthymic temperament as a protective factor or depressive, cyclothymic, irritable and anxious temperament as risk factors in etiology, prevention and treatment of addiction.</p>

In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed. Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound. These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile. ESI should be used in the positive mode for all analytes except gamma-hydroxybutyrate, for which the negative mode should be applied. The Hypercarb column exhibited superior retention of the analytes and was therefore selected for further optimisation. The dimensions of this column were 2.1 x 50 mm and the particle size 5 μm, connected to a 2.1 x 10 mm precolumn containing the same packing material. The optimum of the flow rate and the column temperature were 250 μl/min and 20 ºC respectively. For the separation of gamma-hydroxybutyrate, gamma-butyrolactone and 1,4-butanediol the mobile phase consisted of 100% water with 5 mM formic acid. Thereafter a gradient, up to 70% acetonitrile with 5 mM formic acid, was used in order to elute amphetamine and methadone. Efforts were also made to find an internal standard for the method. However, none of the compounds tested was found suitable. In order to get the method usable for routine analysis, which is the goal, further work is required. A suitable internal standard needs to be added to the method and thereafter work remains with validation of the method.

The thesis focuses on the subjectively perceived changes in the lives of persons in the methadone maintenance treatment program, on their experiencing of the changes and subjective judgment of the treatment. The topic is treated according to the Bio-Psycho-Socio-Spiritual Model of Addiction. The theoretical part deals with the quality of life and the subjectively perceived well-being and defines six dimensions of well-being on which the practical part of the thesis is based. It also elaborates on the Bio-Psycho-Socio-Spiritual Model of Addiction in the context of the methadone maintenance treatment. Moreover, it describes the factors in life change and the motivation to change. The last theoretical chapter focuses on the opioid substitution treatment as such and more specifically on the methadone maintenance treatment. The practical part presents the results of the research. The aim of the thesis is to analyse how the persons in the methadone maintenance treatment program in České Budějovice perceive life changes. A qualitative research was chosen for that purpose. The data were obtained through the technique of narrative interview. The research group consisted of four respondents who were on the methadone maintenance treatment program. The results show that the subjectively perceived changes in the lives of the persons in the methadone maintenance treatment program relate to five out of six dimensions of well-being. No changes were recorded in the dimension concerning the sense of life, in other words, even after a several month methadone maintenance treatment these persons perceive no goal of their lives. Important consequences for work with these persons can be drawn from that, especially for therapists in opioid substitution centres, who should develop spirituality aspects of persons.
