What is toxicology?
The definition of toxicology is "science of eater". It is a study of contradictory effects of physical substances or chemicals on living organisms. Because toxicology is a constantly developing medical science, our understanding of science is also. Knowledge of the adverse effects of toxic substances on the body proceeds with medical knowledge. They used poisonous plant extracts for hunting and warfare. Throughout history, hemlock, opium, arrows and certain metals are used as a poisoning of enemies.
famous victims of poisoning include Claudius, Cleopatra and Socrates. The founder of toxicology is considered to be a Spanish doctor named Orifila. It has shown the effects of poisons on organs and their related tissue damage. The word is taken from the Greek xeno , which means a "stranger". Xenobiotics do not only mean toxic effects, but can also produce beneficial effects as in the case of drugs. While high doses of certain toxins in the body can lead to death, smaller doses may be harmless or even beneficial. This is known as a relationship dávávka-response, main concept of toxicology. An example of chemical toxin is cyanide, while biological toxin could be a snake poison and physical toxin could be radiation. Scientists who study and determine the effects of toxicology are called toxicologists .
The effects of toxicity are complex and many affecting factors. The toxin dose is extremely important. For example, some chemicals are naturally toxic. Others are not toxic until they are absorbed and chemically changed in the body. Many toxins only affect specific organs. Objakmile is absorbed, it can damage any tissue or cell with which they come into contact.
Toxicology is also selective. Toxins can damage different types. Antibiotics are practically non -toxic to humans, but are selectively toxic to microorganisms. Insecticide is a deadly toxin for insects, but is relatively non -toxic to animals. Age is also very importantTeam factor in the adverse effects of toxins on the body. Some toxins may be more harmful to young children and seniors than for adults.
The ability to absorb the substance into the body is also an important factor in toxicology. Almost all alcohol is easy to absorb. It is assumed that toxins in red wine have beneficial aspects, if they are accepted slightly, but when they are collected in large quantities, toxins may become harmful and lead to alcohol poisoning. You may eventually need toxic properties of aspirin to help calm the headache from the toxic effects of the wine.
