For centuries , before infrigidation , an honest-to-goodness Russian practice session was to drop a frog into a pail of milk to keep the milk from cross . In modern times , many believed that this was nothing more than anold wives ’ tale . But researchers at Moscow State University , led by organic pill pusher Dr. Albert Lebedev , have shown that there could be some benefit to doing this , though of course of instruction in the final stage you ’ll be drinking milk that a Gaul was in .
Ice box first became usable to consumers in the former to mid-19th century and , with that , the trash trade became expectant business . New England and Norway became major purveyors of ice , but anywhere it was dusty , ice was a major exportation . Usually made out of wood with atomic number 50 or zinc walls and insulating material textile like sawdust , bottle cork , or chaff , frappe box were popular until they were provide obsolete by the electric refrigerator get down around the 1930s .
Jacob Perkins invented the first version of the refrigerator in 1834 when it was name that the hazardous compound ammonia , when liquify , had a cooling effect . But it was n’t until the late 1920s when Freon was develop by General Motors and DuPont as a “ nontoxic ” cooling agent , and replaced ammonium hydroxide , that icebox for consumers protrude to win grip .
Despite the preponderance of ice in parting of Russia , in certain small rural Russian village many did n’t have access to water ice boxes , so they had to find way to keep things cold and unspoiled . A practice developed , that continued into the twentieth century , as described by Dr. Lebedev from retentiveness from his puerility ,
[ For ] little portions of milk to drink , they used to put [ a ] toad frog inside … A small frog over there could foreclose the milk from being muck up .
This rather peculiar exercise was an intake for a work and , then , a breakthrough that may conduct to a meaning new source of antibiotics . In 2010 , scientists from United Arab Emirates University made an announcement that the secretion from certain toad ’ skin have antibacterial and fungicidal properties . Using species native to African countries , they study the compounds coming from the toad frog , which are known as antimicrobic peptides and are a string of amino group superman .
After isolating these compounds , they began testing them against various bacterial infections . For example , the dreaded “ Iraqibacter , ” a drug - resistant bacterial infection that has been known to hit wound soldier in Iraq could ( once again , potentially ) be fought with a chemical compound found in the skin of a mink frog that are native to North America . secretion from a foothill four - legged frog may have the potential to contend the well - known resistant MRSA staph skin contagion .
In 2012 , scientist from Moscow State University decided to take this a step further by breaking down the compounds and studying the individual peptides . In a study entitle “ Composition and Antimicrobial Activity of Skin Peptidome of Russian Brown Frogs ” published in the Journal of Proteome Research in November 2012 , and using Russian brown frogs ( which are comestible and considered a fragility ) , they extracted secretion by applying electrodes .
What came out was a cocktail of 76 unlike peptides that all had different dimension . Michael Zasloff , now a professor at Georgetown University , but formerly a researcher with the National Institutes of Health say in an interview that , “ What is amazing is that no two toad frog have the same cocktail . They ’re all different , and all beautifully tuned to share with the microbes that these animals present . ”
As promising as the results are so far , many scientists are skeptical of any real benefit coming from them . For example , Jun O. Liu , a professor of pharmacology at John Hopkins University School of Medicine , express in reference to other patent natural pass “ magic antibiotics , ” “ There are lifelike substances that work in a lab attractively but then when you give it to a human being it ’s totally inactive or it ’s toxic . ”
While this all may or may not ultimately be medicinally helpful for humans , begin hundred ago sure Russians seem to have been on to something with lay frogs in milk to delay it spoiling . Although , I think we can all check that putting a frog in one ’s milk takes a back derriere to the other geezerhood - old way to store milk without infrigidation - work it into delicious cheese .

The world frog population is currently dwindling . For example , the United States amphibian universe ( which includes batrachian , toads , salamanders , and newts ) has been go down by 3.7 percent per year of later , fit in to a U.S. Geological Survey released in May 2013 . While the study did n’t give stiff answers to why this happening , the scientist in the report think over that potential factors could include climate change , disease , and drought .
“ Freon ” is the craft name used for a group of chemicals get it on as chlorofluorocarbons , or CFCs . Refrigerators and melody conditioners were rise to habituate these chemical and were sold as consumer products for the domicile . Today , of course , it has since been discovered that there are irrefutable link to CFCs , Freon , and the depletion of the Ozone stratum .
