Topic
In the practices, the students will carry out laboratory experiments involving methods used for in vitro toxicity testing. On prokaryotic and eukaryotic cells, including cells of animal and human origin, they examine the cyto- and genotoxic effects of xenobiotics of toxicological relevance (e.g. mycotoxins, metal ions, and enzyme inducers) and of UV radiation; they analyze the binding of chemicals (e.g. ochratoxin A) to human albumin, and the effects of some drugs on the expression of cytochrome P450 (CYP) genes. The students will be acquainted with the principles of the methods used, the mechanisms of action of the toxicants studied, the details of the experimental techniques, as well as the statistical analysis, presentation and interpretation of the experimental results. The laboratory work will be carried out in an interactive fashion. The students will perform the experiments jointly according to a detailed protocol previously provided for them.

Reading material
Obligatory literature
Literature developed by the Department
A detailed description of each practice (handout) will be available for the students on Neptun in advance of each practice. The handout will explain the principle of the methods, characterize the toxicants to be tested, describe the necessary reagents and eqipment, the steps of the experiments (protocol), the presentation, statistical analysis and evaluation of the the results. The students are expected to review the handout thoroughly before taking part on the practice.

Conditions for acceptance of the semester
Maximum of 15 % absence allowed
Mid-term exams
The performance of students during laboratory practices will be evaluated and graded with a practical course mark, which will be based mainly on the quality of their written reports (laboratory notes) of each practice, however, their preparedness for the practices will also be considered.
Making up for missed classes
Missed classes cannot be made up.
Exam topics/questions
The performance of students during laboratory practices will be evaluated and graded with a practical course mark, which will be based mainly on the quality of their written reports (laboratory notes) of each practice, however, their preparedness for the practices will also be considered.
