Tøffe bakterier svake for tårer
Et stoff som finnes naturlig i menneskets sekreter, tar knekken på bakterien som skaper store problemer for pasienter med cystisk fibrose. Nå håper forskerne stoffet kan tas i bruk i behandling av denne sykdommen. Står det å lese i en artikkel fra forskning.no i fra 2002.
Artikkelforfatteren skriver videre: “Laktoferrin finnes i tårer, slim og morsmelk. Ny forskning viser at stoffet hindrer bakterien Pseudomonas aeruginosa i å lage såkalte biofilmer. I disse biofilmene ligger bakteriene godt beskyttet mot antibiotika.” – http://forskning.no/sykdommer-mikrobiologi/2008/02/toffe-bakterier-svake-tarer.
Ny forskning ? Hvis man går tilbake til vitenskapmagasiner fra 20 og 30 tallet, så kan det jo se ut til at man hadde kommet lengre i forskningen rundt tårer som et antibakterielt stoff til medisinsk bruk den gang enn en i dag. Kan noe forklare meg hvordan det er mulig ?
Tears a powerful germicide – Popular Science october 1928 page 57:
“Teardrops may mean sorrow, but chemically they are blessing.
Tears are composed of a chemical, called “lysozyme”, which is probably
the most powerful germ killer known. Fredrick Ridley of the Royal Society of Medicine in London, experimenting with human tears, has found that one teaspoonfull of the pure chemical contained in them has antiseptic powers equal to more than a hundred gallons of salty water against certain eye bacteria.
The same substance, he says, can be found in white corpuscles of the blood which continually wage war on destructive bacteria invading the body. Eventually it may be possible to extract the powerful chemical in sufficient quantities from animal bodies to place it in general use as a non poisonous antiseptic. – https://books.google.no/books?id=cicDAAAAMBAJ&printsec=frontcover&dq=popular+science+1920&hl=no&sa=X&ei=QxVLU-jALOjmywOlx4DIAw#v=onepage&q=popular%20science%201920&f=false
Tears poison to germs – Popular Mechanics aug 1931 page 208:
Tears have a very practical purpose. An english biologist has dicovered that tear fluid, even greatly deluted, is an exceedingly powerfull destroyer of bacteria.
The bacteria poison in tears is so strong that a solution of 40, 000 parts of water to one of the fluid fully retain its germicidal powerful antiseptic in the tear ducts undoubtedly protects the eye from many germ carried ills. – https://books.google.no/books?id=TeQDAAAAMBAJ&pg=PA208&lpg=PA208&dq=Tears+a+powerful+germicide&source=bl&ots=9cU0ggnpCH&sig=AfusuGnBYGTTDGt9qmx4gKAvQw4&hl=no&sa=X&ved=0ahUKEwjQquiZs6fOAhXCiCwKHTC4BEgQ6AEIJTAC#v=onepage&q=Tears%20a%20powerful%20germicide&f=false
San Antonio Evening News from San Antonio, Texas. June 30, 1922 – Page 23:
Cry If You Life, for to do so releases from the lacrimal glands “Lysozyme,” which an eminent british physician has just discovered is nature ‘s most powerful germicide.
Florence Reed in an emotional outburst – Such a scene has saved countless lives because the tears releasing a quantity of “Lysozyme” have killed germs that might otherwise have entered the system. Sir Almoth’Wright, british Scientist, whose perseverence resulted in the discovery of “Lysozyme.”
The potency of a tear drop, so long guaranteed by poets alone, has now become a scientific truth. As a result of experiments conducted in the laboratory of Sir Almoth Wright in Bt. Mary’s Hospital, London, there has been discovered the existence in human tears of a re- toarkable substance. This substance he has called lysozyme and one tiny drop of it will destroy millions of bacteria. Sir Almoth suspected its existence for a long time.
After six months of experiments he was able to show its existence conclusively and to demonstrate its power to exterminate bacteria. Thus far this substance has not been isolated. When this is accomplished, scientists believe that the most powerful germ-destroying agency known to man will then be available for use.
The germicidal properties of tear drops were first publicly demonstrated by Dr. Alexander of Sir Almoth’s staff at a recent conver- of the Royal Society,- London. In the presence-of several newspaper men he took a tiny drop of tear in a pipette and gave it as a lethal dose to a good many million bacteria which clouded the liquid in a test tube. Almost immediately the tear dissolved every germ in the tube. ‘He further explained ‘ that this secretion — Jy- Bozyme– was present, in nearly all the tissues of the body and in most of the secretions and extractions.
It was at work all the time, he said, destroying many kinds of bacteria. ‘But in” the ae- cretions of the lacrimal or fear glands, a very high distillation of this potent juice took place, which made the teardrop a reservoir of great power.
Dr-; Fleming has not yet announced what are the constituents ? lysozyme, or.even, if it is’ capable of being analyzed. Other scientists have ventured the opinion that the substance may be a very strong salt concentration and in that way derives its sower.
According to the accepted definition, a tear. Is “a drop of the saline liquid secreted by the lacrimal. gland, for moistening the surface of the eye and washing away, foreign bodies. Ordinarily the tears are conveyed away by the lacrimal canals to the laerimal sac, whence they pass into the inferior meatus (in the nose) and mingle with the mucous secretion, but under the influence of strong emotion or by spasmodic contraction of the muscles of the eye, as in coughing or immoderate laughter, they overflow the cheeks.”
But tears not only wash away foreign bodies, they dissolve them, if such bodies are not too large. Almost everybody has had the experience of getting some tiny particle in his eye and having it dissolve there. And from this common experience, Dr. Fleming built up an hypothesis which has resulted in the present discovery. Sneeze and Kill Germs Commenting on the London scientists announcement a New York editorial writer said: “Nature has many ways of protecting the body. There is salt ‘in tears and salt is one of the greatest protectors. Salt, acid and violent shaking are deadly to germs. When you sneeze you kill gerins, just as you would be killed if an elephant stepped on you.”
To this writer, the London scientists claims as to the tear drop seem entirely credible. Ha doesn’t see anything unreasonable in Dr..Fleming’s hope that ultimately human tears can be utilized to immense advantage in medicine and chemistry. But before that time comes the problem of getting a world’s supply of tears organized, will have to be solved.
It is unlikely that an artificial method of pro – The Gish Girls – Lillian, the movies most copious weeper, has produced enough tears to destroy billions of germs. Jane Cowl, the stage’s greatest weeper, may, have a new value placed on her tears. Ducing tears will lie discovered.
From Dr. Fleming’s statement it is gathered that the peculiar processes of the lacrimal gland is necessary to the creating of lysozyme. The only plentiful sources of supply, therefore, are human beings. So now the maiden’s tear, long celebrated by Xmvspaper feature Servli lovers and makers of verses, has a commercial value.
The possibilities suggested by this revaluation of tears are many and widespread. Will young women who are particularly adept to the exercise, start weeping for a living, just as hundreds of people now sell their blood to hospitals at the rate of $40 a pint? Will some unscrupulous person kidnap Jane Cowl or Florences-Seed or the Gfsh girls, force them to cry continuously and then bottle up the tears for sale?
Will mothers stand around waiting for their babies to start wailing in order to catch the golden drops as they cry ? The suggestions are fanciful, to be sure, but are well within the limits of the possible. The chances are that a “class of professional weepers will spring up from whom medical men and chemists will be able to obtain all the tears from are needed.
But even professional weepers can’t make them flow of will all the time. For the occasions when the Primal glands’ become stubborn, it would seem appropriate for the weeper to bring into use an onion or perhaps a bit of W gas such as was used during the war.
Nature’s Protective Germicide This gas induces such a copious Sow thai ono wounded by the downpour. No ill after effects are experienced from the use of the gas, so it could be used freely. One commentator, however, has suggested that if nature has placed lysozyme in human tears, they were placed there for the protection of each human being. In other words, if any one (cried too copiously for outside consumption, it would take away chemicals needed for the cleansing of his own body.In that case science might have to turn else where.
Dr. Fleming declares that while lysozyme appeared nowhere else in such abundance as in human beings, there are traces of the substance in tissues of the lower animals and certain vegetables such as the-turnip. But if,vegetables could be utilized profitably, the fatal possibilities in excessive tear losses might bring about some fearful consequences. The tragedy of the maiden who cried herself to death might then figure, prominently in the newspaper, or at least in the melodramatic fare of that day.
The scenario would go something like this: The unscrupulous bounder offers his hind In marriage to the banker’s beautiful daughter, but she rejects him scornfully. The unscrupulous bounder here upon determines that he will have her at all-costs and that even if he cannot win her, he will at least break her spirit. A comedy of tears he hires a gang of ruffians. They crnptur* the B. B. D. and take her to a lonely, hut in the woods where the unscrupulous bounder awaits her.
They tie her up to a post in the centre of the cabin, then bounder taunts her, hoping that she will burst into tears. But the maiden being proud, only tosses her head. The unscrupulous bounder then produces an onion. She weeps, but not enough. He then goes outside, closes the doors, hermetically seal all cracks, and fill the cabin with lacrimogene, or tear gas. The beautiful maiden is slowly weeping herself to death, when peerless Paul dishes up in his low sjupg plane and rescues her. He sponges up the tears, bells them and with the money thus acquired retire with his bride to a life of ease and luxury.
Other possibilities of the new discovery are not so farcical. If tear drops do become valuable, righteous laws will have to be made in order to prevent exploitation of innocent persons. Meanwhile Dr. Fleming is continuing experiments in an effort to isolate lysozyme.
Sir Almoth Wright, in whose laboratory that the experiments have been conducted in, is one of the most prominent scientists in England. Ha was awarded the Fothergillian gold medal by The Medical Society of London, the Hungarian pri by the International Medical Congress, the’L*. conte prize of the Academie des Science and many others.
He is also the author of many works, chief among which-are “Principlea of Microscopy” and “Studies in Immunization. Sir Almoth is generally thought to be the person that George Bernard Shaw had in mind when he wrote “The Doctor’s Dilemma.” He has been referred to facetiously in England as Sir Almost KgikU Â. – https://www.newspapers.com/newspage/39272888/
