Toxicology

Data

Official data in SubjectManager for the following academic year: 2024-2025

Topic

Toxicology, as a subject, deals with the toxic (including teratogenic and carcinogenic) effects of drugs and xenobiotics (metals, solvents, toxic gases, pesticides, endocrine disruptors, mushroom- and plant-derived toxins, etc.) caused by overdose or excessive exposure. It describes the general aspects of toxicology, the mechanisms of toxicity (including the major influencing factors), the harmful effects and the corresponding symptoms, the diagnostics of the adverse health effects, as well as their prevention and treatment. In addition, toxicity testing and risk assessment of chemicals are also shortly discussed.

Mid-term exams

Students are required to take a test, which are scheduled for last week approximately. These test will contain multiple choice and short essay type questions. We will offer a final grade (5) for those reaching at least 85%. On the other hand, those do not achieve the 85% limit in the test need to perform an oral exam, in the exam period.

Making up for missed classes

Missed classes cannot be made up.

Exam topics/questions

The exam includes each topic discussed during the lectures and presented in lecture slides (available in Neptun Meet Street). In addition to the exam topics, an important part of the exam is answering questions that aim at assessing the general knowledge of the student. Students have to discuss in details two major exam question.

Exam topics/questions:

1. The scope of toxicology (human intoxications: occurrence and classification. causes of poisoning-related death), management of the poisoned patient (emergency care, diagnostics, decontamination, antidotes, enhancement of the elimination of toxicants, supportive care).

2. Drug intoxications I: drugs decreasing consciousness, drugs causing agitation.

3. Drug intoxications II: drugs causing cardiac dysfunction, drugs interrupting blood coagulation.

4. Drug intoxications III: drugs causing metabolic disorders or tissue necrosis.

5. Toxic hypoxias: carbon monoxide, hydrogen cyanide and cyanogen compounds, hydrogen sulfide, methemoglobin formers.

6. Toxicology of solvents: hydrocarbons and their halogenated derivatives, alcohols, carbon disulfide.

7. Toxicology of metals: metal chelators, protective mechanisms, toxic effects of metals.

8. Toxicology of pesticides (insecticides, herbicides, fungicides, rodenticides, and fumigants), endocrine disruptors.

9. Teratogens and teratogenesis.

10. Poisonous mushrooms, chemical warfare agents.

11. Chemical carcinogenesis, toxicity testing, and risk assessment.
12. Everyday toxicology
13. Suicidal toxicology
