Wednesday’s Topic for group discussion in “Group of Forensic Experts” was- 👉 How Poison affect body? Or Administration of Poison. 👉– Best answer is given by - Susrita Sahoo - “Poisons work by changing the speed of different body functions, increasing them (for example, increasing the heart rate or sweating), or decreasing them (sometimes to the point of stopping them entirely, like breathing). For example, people poisoned by parathion (an insecticide) may experience increased sweating. Increased sweating due to parathion poisoning results as follows. The first step is the biochemical inactivation of an enzyme. This (1) biochemical change leads to a (2) cellular change (in this case an increase in nerve activity). The cellular change is then responsible for (3) physiological changes, which are the symptoms of poisoning that are seen or felt in particular organ systems (in this case the sweat glands). The basic progression of effects from biochemical to cellular to physiological occurs in most all cases of poisoning. Depending on the specific biochemical mechanism of action, a poison may have very widespread effects throughout the body, or may cause a very limited change in physiological functioning in a particular region or organ. Parathion causes a very simple inactivation of an enzyme which is involved in communication between nerves. The enzyme which parathion inactivates however, is very widespread in the body, and thus many varied effects on many body systems are seen besides sweating.” 🤢The action of all poison is almost same. 👉most of the poison affects the person immediately, if not, the poison is eliminated from the body by excretion or gets metabolized or detoxified into non-toxic metabolite which is eliminated slowly.
