Radioactivity measurement involves quantifying the amount of radioactive material and the intensity of radiation emitted. Various instruments and techniques are used for this purpose. Here are some commonly used methods for measuring radioactivity: 1. Geiger-Muller Counters Principle: Geiger-Muller counters detect ionizing radiation by counting the number of electrical pulses produced when ionizing particles pass through…
Radiopharmaceuticals are pharmaceutical formulations containing radionuclides (radioactive isotopes) that emit gamma rays or positrons. Nuclear medicine designs these compounds to diagnose or treat various medical conditions. Radiopharmaceuticals incorporate a biologically active molecule (typically a drug or a biological targeting molecule) with a radioactive isotope, creating a compound that imaging techniques can trace within the body….

compound that tends to shrink or constrict body tissues and precipitate the protein, and astringent forms a protective layer on the surface. – Due to their protein action, astringents can reduce cell permeability. – This reduces local edema, exudation, and inflammation. – The word “astringent” derives from the Latin “adstringere”, meaning “to bind fast”. –…
Sodium nitrite is sometimes used as part of an antidote regimen in cases of cyanide poisoning. Cyanide poisoning can occur through exposure to certain chemicals, including hydrogen cyanide and cyanogenic compounds. Sodium nitrite is used to induce methemoglobin formation, which can help to counteract the effects of cyanide poisoning. Here’s an overview of its use…
Activated charcoal (AC) is a highly effective, widely used adsorbent in clinical toxicology for the treatment of poisoning and drug overdose. It works by binding toxins in the gastrointestinal (GI) tract, preventing their systemic absorption. Activated charcoal is an inert, tasteless, and odorless powder with a large surface area due to its porous nature. It…
Poison refers to any substance, chemical, or organism that, when introduced into or absorbed by a living organism, can cause harm, injury, illness, or death. Poisons disrupt normal physiological functions and can have toxic effects on cells, tissues, and organ systems. They can be ingested, inhaled, absorbed through the skin, or injected and may vary…
The use of psychotropics, narcotics, alcohol, and tobacco products can have significant social impacts on health productivity and may contribute to suicidal behaviors. Here’s an overview of how these substances can affect social well-being: Psychotropics Social Impact: – Stigma and Discrimination: Society often stigmatizes mental health conditions, commonly treated with psychotropic medications, leading to discrimination…
