First graduates' perceptions on a problem-based and task-based learning curriculum.

INTRODUCTION: Determination of graduates' perceptions and suggestions is essential in the evaluation of educational programmes. Dokuz Eylul University School of Medicine (DEUSM), the country's first medical school implementing a Problem-Based Learning (PBL) and Task-Based Learning (TBL) programme, graduated the first students of its new educational programme starting from the 2002-2003 academic year. The aim of the present study is to determine first graduates' perceptions on their self-efficacy and school's educational programme's efficacy. METHODS: In June 2003, 51 graduating students were asked to use five-point scales to evaluate: the content of the educational programme, the educational methods, communication with educators, assessment methods and instruments, the efficacy of each year of their undergraduate programme and the overall program, their satisfaction levels about educational programme regarding the acquisition of knowledge and skills, their self-efficacy and contentment level of being a physician. RESULTS: In the content of educational programme, the highest score was attributed to "acquisition of behavioural objectives" and the lowest score to "acquisition of basic science knowledge". Regarding the efficacy of educational programme, the highest score was attributed to "communication with educators". The highest scores regarding the satisfaction levels on the acquisition of knowledge and skills provided by the School were attributed to "implementing basic professional procedures" and "history taking" and the lowest score to "selecting appropriate treatment". CONCLUSION: The graduating students' mainly positive evaluations regarding the efficacy of DEUSM's new educational programme were considered as supportive reflections on the new educational programme. Further studies to monitor our graduates' future professional performances are being envisaged.

Sexual attitudes and behaviors among medical students in Dokuz Eylul university, Turkey.

Gaining a healthy sexual attitude and behavior and being able to show appropriate approaches to patients in terms of sexual issues are important acquisitions for medical students. The aim of the present study was to determine, compare, and evaluate the sexual attitudes and behaviors of Dokuz Eylul University Faculty of Medicine students. An anonymous questionnaire was filled in by first- and sixth-year students in order to determine their sexual attitudes and behaviors. While information sources in the adolescence period for both genders were friends in the first place, these sources were mostly mothers, books, newspapers--magazines for females, and newspapers--magazines and television for males. The opinion of males about having sexual intercourse before marriage for males was positive, and females were more tolerant about males having this experience before marriage as compared to females having sexual experience before marriage. Rates of expression of having sexual intercourse and masturbation were found to be higher for male students. The first sexual experience with a sex worker or sentimentally insignificant partner was high among males. In general, the rate of condom use was lower, and the rate of coitus interruptus was found to be higher than in foreign studies. All the students declared 'my own will and values' as the most frequent factor affecting their sexual attitudes and behaviors, and high rates for 'social factors', 'religious requirements', 'the expectations of families', and 'protection from sexually transmitted diseases' were observed. The findings lead to the conclusions that gender differences exist in the sexual attitudes and behaviors of medical students; the enhancing effect of the traditional structure on gender discrimination is still continuing; students are not provided with sufficient scientific approach or training prior to the university education; and beyond biomedical training, they should receive more support in those fields during their medical education.

Histological and biochemical effects of cigarette smoke on lungs.

In this study, rats were made to inhale cigarette smoke in a specifically prepared container for different periods. The lung tissue samples of the subjects were examined by light microscopy, transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Malonaldehyde, one of the free oxygen radicals was determined in lungs and plasma. The catalase activity level of erythrocyte and arginase levels were determined. Three groups were formed. The rats in the Ist and IInd groups were made to inhale cigarette smoke for 30 and 60 minutes a day for a total period of 3 months. Control group, the rats in the IIIrd group (controls) were made to inhale clean air during the same periods. An increase in the number of macrophages was observed in the pulmonary tissue of the exposed groups. Especially in the group that inhaled the smoke for long periods, the number of macrophages and the inclusion bodies contained in them increased. These differences could easily be observed in TEM studies. In the light microscopy and SEM observations, it arouse attention that the alveolar macrophages occurred as sets and their activation increased. Depending on the length of the exposure to cigarette smoke, an increase in the number of macrophages was observed. Statistically significant increases were determined in the malonaldehyde levels of pulmonary tissue and plasma when compared to the control group. Besides significant increases were found in the catalase activity levels of erythrocytes in the experimental groups.

The effect of xylene inhalation on the rat liver.

In this study, 11,284 mg/m3 (2600 ppm) of xylene was administered for 8 hours a day to pregnant rats by means of inhalation, starting from the sixth day of their pregnancies. Furthermore, while a group of non-pregnant rats inhaled the same amount of xylene during the same period, the control group inhaled clean air. Consequently, in addition to the embryotoxic effects of xylene, the effects on the various tissues of the mothers and their litters were observed light and electron microscopes. No external anomalies were observed in any of the rats born at the end of the 21st day, and there were no macroscopic defects in their organs either. While following xylene inhalation no structural defects in the kidney and pancreas was found, expansions in the smooth endoplasmic reticulum of the liver tissues, increases in the lysosomes, and defective mitochondrion structures were found in the pregnant and non-pregnant rats. It was noticed that xylene in particular caused structural defects in the liver of the fetus. Compared to the control groups, increases were observed in the activities of the AST, ALT, ALP, and Arginase enzymes in the liver.
