He was the first to discover the antiseptic properties of Phenol">carbolic acid (phenol). Biography Lemaire, pharmacist and chemist, had been instructed by Dr. Ferdinand Le Beuf, pharmacist in Bayonne, to experiment with a preparation of coal tar, emulsified using an alcoholic tincture of saponin. Lemaire recognized antiseptic properties in this preparation, due to the carbolic acid (phenol) from coal tar, and published the results of this research in 1860 in a book entitled ''Du coaltar saponiné, désinfectant énergique'' (''Saponinated coal tar, an energetic disinfectant''). Lemaire then experimented with the effects of phenol alongside those of coal tar, and presented the results of all his work in a new book published in 1863: ...

Aqueous Solution
An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, or sodium chloride (NaCl), in water would be represented as . The word ''aqueous'' (which comes from ''aqua'') means pertaining to, related to, similar to, or dissolved in, water. As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent in chemistry. Since water is frequently used as the solvent in experiments, the word solution refers to an aqueous solution, unless the solvent is specified. A ''non-aqueous solution'' is a solution in which the solvent is a liquid, but is not water. (See also Solvent and Inorganic nonaqueous solvent.) Characteristics Substances that are ''hydrophobic'' ('water-fearing') do not dissolve well in water, whereas those that are ''hydrophilic'' ('water-friendly') do. An example of a hydrophilic substance is sodium chlo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

19th-century French Physicians
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order Of Isabella The Catholic
The Order of Isabella the Catholic ( es, Orden de Isabel la Católica) is a Spanish civil order and honor granted to persons and institutions in recognition of extraordinary services to the homeland or the promotion of international relations and cooperation with other nations.

James Young Simpson
Sir James Young Simpson, 1st Baronet, (7 June 1811 – 6 May 1870) was a Scottish obstetrician and a significant figure in the history of medicine. He was the first physician to demonstrate the anaesthetic properties of chloroform on humans and helped to popularise its use in medicine. Simpson's intellectual interests ranged from archaeology to an almost taboo subject at the time: hermaphroditism. He was an early advocate of the use of midwives in the hospital environment. Many prominent women also consulted him for their gynaecological problems. Simpson wrote ''Homœopathy, its Tenets and Tendencies'' refuting the ideas put forward by Hahnemann. His services as an early founder of gynaecology and proponent of hospital reform were rewarded with a knighthood and by 1847 he had been appointed as physician to the Queen in Scotland. Simpson was a close friend of Sir David Brewster, and was present at his deathbed. His contribution to the understanding of the anaesthetic proper ...

Joseph Lister
Joseph Lister, 1st Baron Lister, (5 April 182710 February 1912) was a British surgeon, medical scientist, experimental pathologist and a pioneer of antiseptic surgery and preventative medicine. Joseph Lister revolutionised the craft of surgery in the same manner that John Hunter revolutionised the science of surgery. From a technical viewpoint, Lister was not an exceptional surgeon, but his research into bacteriology and infection in wounds raised his operative technique to a new plane where his observations, deductions and practices revolutionised surgery throughout the world. Lister's contribution to the fields of physiology, pathology and surgery were four-fold. He promoted the principle of antiseptic surgical care and wound management while working as a surgeon at the Glasgow Royal Infirmary by successfully introducing phenol (then known as carbolic acid) to sterilise surgical instruments, the patient's skin, sutures, the surgeon's hands and the ward. Secondly he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiseptic
An antiseptic (from Greek ἀντί ''anti'', "against" and σηπτικός ''sēptikos'', "putrefactive") is an antimicrobial substance or compound that is applied to living tissue/skin to reduce the possibility of infection, sepsis, or putrefaction. Antiseptics are generally distinguished from ''antibiotics'' by the latter's ability to safely destroy bacteria within the body, and from ''disinfectants'', which destroy microorganisms found on non-living objects. Antibacterials include antiseptics that have the proven ability to act against bacteria. Microbicides which destroy virus particles are called viricides or antivirals. Antifungals, also known as antimycotics, are pharmaceutical fungicides used to treat and prevent mycosis (fungal infection). Surgery The widespread introduction of antiseptic surgical methods was initiated by the publishing of the paper ''Antiseptic Principle of the Practice of Surgery'' in 1867 by Joseph Lister, which was inspired by Louis Pasteur's ...

Saponin
Saponins (Latin "sapon", soap + "-in", one of), also selectively referred to as triterpene glycosides, are bitter-tasting usually toxic plant-derived organic chemicals that have a foamy quality when agitated in water. They are widely distributed but found particularly in soapwort (genus Saponaria), a flowering plant, the soapbark tree (''Quillaja saponaria'') and soybeans (''Glycine max'' L.). They are used in soaps, medicinals, fire extinguishers, speciously as dietary supplements, for synthesis of steroids, and in carbonated beverages (the head on a mug of root beer). Structurally, they are glycosides, sugars bonded to another organic molecule, usually a steroid or triterpene, a steroid building block. Saponins are both water and fat soluble, which gives them their useful soap properties. Some examples of these chemicals are glycyrrhizin, licorice flavoring; and quillaia (alt. quillaja), a bark extract used in beverages. Uses The saponins are a subclass of terpenoids, the larges ...

Coal Tar
Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It is a type of creosote. It has both medical and industrial uses. Medicinally it is a topical medication applied to skin to treat psoriasis and seborrheic dermatitis (dandruff). It may be used in combination with ultraviolet light therapy. Industrially it is a railroad tie preservative and used in the surfacing of roads. Coal tar was listed as a known human carcinogen in the first Report on Carcinogens from the U.S. Federal Government. Coal tar was discovered circa 1665 and used for medical purposes as early as the 1800s. Circa 1850, the discovery that it could be used as the main ingredient in synthetic dyes engendered an entire industry. It is on the World Health Organization's List of Essential Medicines. Coal tar is available as a generic medication and over the counter. Side effects include skin irritation, sun sensitivity, allergic reactions, and skin discoloration. ...
