Antiseptics and Joseph Lister

Preservatives and Joseph Lister preservatives are physical or chemical agents that prevent spoilage, infection, and similar changes in food and body tissues by preventing the destruction or destruction of microorganisms. Long ago, food was preserved by the use of preservatives such as cooking heat; nitrates, salt and vinegar are added to Corning and pickling; meat and wood smoke (including creosote, chemical Similar to carbonic acid). In modern times, the main preservatives used to preserve food are hot and cold during canning, pasteurization and refrigeration.

Joseph Lister, known as the father of antimicrobial surgery, can apply the fermentation cause of Pasteur to the process that causes infection and gangrene. By applying the theory of bacteriology to surgery, Lister changed the patient's prognosis and the path of surgery and laid the foundation for modern surgery. Lister, a British-born Quaker's family, studied and worked in London and Scotland, but in 1846 he was an avid surgeon from a young age and participated in the first anesthetic surgery. In the early days of his surgery, few people knew about the role of infection and bacteria in disease spread. Surgery is dangerous - 35% of amputations lead to infections due to non-sterile practices. Lister's research is contrary to previous theory

British surgeon Joseph Lister was inspired by the work of Pasteur. Lister applies it to surgery using Pasteur disease bacterial theory, which is the beginning of modern disinfection surgery. Lister is sterilized using a solution called carbonic acid (phenol). Carbonic acid reduces surgical patient's mortality by 45%. Spray the solution using hand held spray in the operating room. Microorganisms can be divided into five groups: bacteria, fungi, insects, protozoans, and viruses. Bacteria are prokaryotic unicellular organisms, including deoxyribonucleic acid (DNA) and ribonucleic acid RNA, but without defined nuclei. Bacteria can be divided into cocci (spherical), bacilli (linear bars), spirals or curved bars. Because bacteria are colorless and difficult to observe with an optical microscope, Gram staining is a widely used method of medical bacteriology.
