Protein Binding

Protein Binding Many drugs interact with plasma or tissue proteins or other macromolecules, such as melamine or DNA, to form a drug- macromolecule complex. The formation of a drug protein complex is often named as drug-protein binding. Drug protein binding may be a reversible or irreversible process. The formation of drug protein complex is named […]

Chemical Sterilization

Chemical sterilization involves the utilization of certain chemicals to cause microbial termination. For this, the most used materials are chlorine, formaldehyde, glutaraldehyde, quaternary ammonium salts, and ETO. Alkylating gases Principle: Alkalization of essential metabolites of microbes, affecting reproductive         Alkalization occurs by replacing hydrogen on sulfhydryl, amino, carboxyl, hydroxyl-groups with a hydroxyl radical Example:                                                                                                                                                ethyleneoxide,betapropiolactone,glutaraldehyde,formaldehyde,propylene oxide Ethylene oxide

Vitamins

Vitamins Vitamins are the chemical compounds that are required in low amounts but are essential for normal growth and metabolism. Vitamins may be divided into two groups: the fat-soluble vitamins (vitamins A,D,E and K) and the water-soluble vitamins (vitamin B and vitamin C). Vitamin A Vitamin A was the first fat-soluble vitamin identified (in 1913).

Cancer

What is Cancer? Cancer is the deregulation of normal cellular processes.  Cells that have been transformed tend to proliferate in an uncontrolled and deregulated way and, in some cases, to metastasize (spread).  Cancer is not one disease, but a group of more than 100 different and distinctive diseases. Cancer can involve any tissue of the

Intravenous Anesthetics

Intravenous Anesthetics Intravenous anesthetics are a group of fast-acting compounds that are used to induce a state of impaired awareness or complete sedation. Commonly used Intravenous anesthetics include Propofol ,etomidate, ketamine and barbiturates BARBITURATES The three barbiturates most used in clinical anesthesia are sodium thiopental, thiamylal, and methohexital. Sodium thiopental has been used most frequently for inducing
