Questions- What is difference between Poison, Toxin And Venom?

Answer- Poison, toxin, venom are terms for any substance that injures the health or destroys life when absorbed into the system. ☣ Poison: Poison, in biochemistry, a substance, natural or synthetic, that causes damage to living tissues and has an injurious or fatal effect on the body. ☣ Toxin: A toxin is a poison produced by an organism. ☣ Venom: Venom is especially used of the poisons secreted by certain animals, usually injected by bite or sting.

Question- What quantity of a poison would be necessary to produce a lethal out-come in a human victim?

Answer- There are several considerations to keep in mind for poisoning. Studies revealed that small doses of a substance might be harmless or beneficial, whereas larger doses could be toxic. This is now known as the dose-response relationship, a major concept in toxicology. A poison is any substance that can cause illness or death when ingested in small quantities. This definition excludes the multitude of substances that cause damage if ingested in large quantities. For example- A dose of aspirin (acetylsalicylic acid) that is harmless to an adult may be poisonous to an infant. Similarly, an elderly person’s tolerance of a substance may be much lower than that of a healthy young adult. Lethal Amount of poison is also depend on person, poison and many other factors, such as; Lethal dosage often varies depending on the method of administration; for instance, many substances are less toxic when administered orally than when intravenously administered.

Fracture: A fracture is a break in a bone. Fractures can range from a hairline crack in the bone to the bone being broken into two or more pieces that no longer line up correctly. A fracture may occur at the same time as other injuries, such as sprains, strains, or dislocations. Recovery time for a fracture can vary from weeks to months depending on a person’s age and health; the type, location and severity of the fracture.

Types of Fractures; Fractures have a variety of names. Below is a listing of the common types that may occur:

Greenstick - Incomplete fracture. The broken bone is not completely separated.

Transverse - The break is in a straight line across the bone.

Spiral - The break spirals around the bone; common in a twisting injury.

Oblique - Diagonal break across the bone.

Compression - The bone is crushed, causing the broken bone to be wider or flatter in appearance.

Comminuted - The break is in three or more pieces and fragments are present at the fracture site.

Segmental - The same bone is fractured in two places, so there is a “floating” segment of bone.

What Causes a Fracture? Fractures occur when there is more force applied to the bone than the bone can absorb. Bones are weakest when they are twisted. Breaks in bones can occur from falls, trauma, or as a result of a direct blow or kick to the body

Smoking and Bone Fracture: Tobacco and nicotine increase the risk of bone fractures and interfere with the healing process, according to a growing body of research. Nicotine can slow fracture healing, estrogen effectiveness, and can counter the antioxidant properties of vitamins C and E. ____________

COOLING OF THE BODY AFTER DEATH A body is not a uniform structure. It’s temperature will not fall evenly and because each body will lie in its own unique environment, each body will cool at a different speed, depending upon the many factors surrounding it.

Variables and factors also affect the rate of cooling of a body and together they show why the sensible forensic pathologist will be reluctant to make any pronouncement on the time of death based on the body temperature alone. These are: 👉 Mass of the body. 👉 Mass/surface area. 👉 Body temperature at the time of death. 👉 Site of reading of body temperature(s). 👉 Posture of the body – extended or curled into a fetal position. 👉 Clothing – type of material, position on the body or lack of it. 👉 Obesity – because fat is a good insulator. 👉 Emaciation – lack of muscle bulk allows a body to cool faster. 👉 Environmental temperature. 👉 Winds, draughts, rain, humidity etc.

James Marsh and the Marsh Test

An important test used in early toxicology was developed in 1836 by chemist James Marsh (1794–1846). In 1832 John Bodle had been accused of poisoning his grandfather with arsenic placed in coffee. Marsh was asked by the prosecution to check the stomach contents of the victim. He used a hydrogen sulfide method and was able to produce a yellow solid consistent with the presence of arsenic. Unfortunately, the solid degraded between the time it was prepared and when it was presented to a jury. To Marsh’s dismay Bodle was acquitted.

Marsh went into his lab with one simple goal: develop a reliable and visually convincing method to detect arsenic in messy and complex samples like tissue and stomach contents. First, he turned to Scheele’s procedure in which arsenic was converted to arsine gas. Marsh knew that under the proper conditions compounds containing arsenic, such as arsine, could be manipulated to form arsenic metal. Magnus had demonstrated that conversion centuries earlier. Marsh realized that metallic arsenic is stable, and if he could capture the arsine gas, he could manipulate it so that metallic arsenic would form on a solid surface. This process is sometimes called “plating out.” This simple idea took Marsh four years to perfect, and the method became known as the Marsh test. This famous procedure was the first reliable analytical test for arsenic. For his efforts Marsh received wide acclaim and a gold medal from the Royal Society of Arts.
