INTRODUCTION: There are only sporadic references in literature regarding general medicine and dentistry student´s preparedness for Histology, study resources and how students might use them in the era of virtual microscopy. METHODS: A structured questionnaire was used to evaluate students´ opinion, with 192 students of general medicine and 82 students of dentistry responding. RESULTS: The dentistry students evaluate their previous knowledge of basic high school disciplines as less helpful when compared to their general medicine colleagues, but this difference diminishes during the first year of medical school studies. Students of dentistry display a better orientation in the amount of study resources (electronic vs printed) and also the ways of their use (practical vs theoretical preparation). The main problems surfacing in the study of Histology have been: the lack of time due to the high demands of Anatomy, problems with correct identification of structures in specimens and correct orientation in a large number of available study resources. Students indicate that they would appreciate the introduction of interactive exercise tests to verify practical and theoretical knowledge. CONCLUSION: We revealed significant differences between students of general medicine and dentistry in terms of student´s preparedness and learning habits. According to our findings, it is still necessary to further develop teaching methods utilising virtual microscopy, taking into account the needs of both general medicine and dental school students.

INTRODUCTION: Virtual microscopy, used as a method to teach histology, has many undeniable advantages. However, the usefulness of this method is somewhat limited by the difficulties students face in finding their way through huge amounts of digital data, compounded by decreased interaction between students and teachers. We describe the results of a recent pilot project which combined the modern teaching methods of active learning, where students themselves present histological slides and make use of the virtual microscopy system. METHODS: Students' responses to a structured questionnaire and examination results were evaluated. RESULTS: We found that a combination of both electronic materials and textbooks was commonly used by students to prepare for practical teaching sessions, with electronic resources being used regularly by the majority of students. No statistically relevant differences were found between the approaches of dentistry vs general medicine students. Cooperation between students' groups during the preparation for individual presentations was seen to be beneficial by a majority of dentistry students; they reported that the introduction of student-led presentations improved their quality of preparation for practical lessons, as well as increasing their participation and activity level in the lessons themselves. These different approaches and motivations between students of dentistry and general medicine are reflected in the test results where dentistry students are more successful. CONCLUSION: We confirm that there are differences in motivation, approaches and examination results between both groups of students, which should be taken into account and which could lead to differentiation of future curricula for both study courses.

There is growing evidence that some members of cytochrome P450 enzymes contribute to regulation of normal prenatal development. CYP epoxygenases (CYP2C and CYP2J subfamilies) convert arachidonic acid into four regioisomeric epoxyeicosatrienoic acids (EETs), biologically active molecules involved in mitogenesis and cell signaling. Almost nothing is known about localization of their expression in tissues during human prenatal development. The spatio-temporal expression pattern of CYP2C8, CYP2C9, CYP2C19 and CYP2J2 in human embryonic/fetal intestines, liver, and kidney was investigated by immunohistochemical method. CYP epoxygenases are expressed already in early stages of development in these embryonic/fetal tissues (as early as 7th week of IUD in the intestines, 5th week of IUD in the liver, and 6th week of IUD in the kidney). In kidney, CYP epoxygenases are expressed in the metanephrogenic blastema (but not in the uninduced mesenchyme) and in the tubular system. In the intestines, diverse CYP epoxygenases distribution along crypt-villus axis could suggest role in cell differentiation. Moreover, we detected higher CYP2J2 level in these organs than in adult tissue samples.

We introduced a new method of teaching practical histology using virtual slides (VS) at the Department of Histology and Embryology in Olomouc. In the database of e-practical sessions there are sets of virtual slides for each topic taught, and several supporting documents available to students that help them to orient easily in the subject of the practical session. We have also introduced practical examination of histology slides with electronic tests on personal computers (PC). We have prepared our own specific set of evaluation questions and allowed students to evaluate this new method of practical sessions. The results of these anonymous questionnaires are of a great importance to our teaching staff, as they represent an important feedback for further improvement of teaching practical histology. Comparing student´s responses in three subsequent academic years, we have found no changes in their highly positive evaluation of the use of PC for observation of virtual slides. Increase in positive responses were observed in answers to questions concerning the use of supporting documents attached to the database of virtual slides (from 50% to 68%) and active preparation of students prior to practical sessions (from 3% to 15%). Students also admitted that they increasingly benefited from the in-course electronic testing (from 86% to 93%) that motivated students to more systematic studies during two semesters of the histology course. They unequivocally preferred electronic forms of examinations over oral ones. On the other hand, students agreed that they were not able to express their theoretical knowledge properly in oral discussions or exams.
