India's Green Revolution Wilts 2010-02-23T01:15:00Z Thus, ammonia is formed at the expense of the urea. Dietetics for Nurses From the quantity of urea present, it is very prone to decomposition, and soon becomes alkaline, especially in warm weather. North American Medical and Surgical Journal, Vol. 2, No. 3, July, 1826 The amount of urea varies considerably, and is evidently under the influence of complicated conditions. A System of Practical Medicine by American Authors, Vol. I Volume 1: Pathology and General Diseases 2012-03-17T02:00:54.097Z It has been suggested that urea is formed by polymerization of ammonium carbonate, and formic aldehyde is synthesized from CO2 and OH2. Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 2 "Baconthorpe" to "Bankruptcy" As the soil's fertility has declined, farmers under pressure to increase output have spread even more urea on their land. India's Green Revolution Wilts 2010-02-23T01:15:00Z From certain researches, carried out as far back as the year 1857, Sir Charles Cameron concluded that the plant could assimilate one of them—viz., urea. Manures and the principles of manuring And should the irritation of the spirit continue, or be augmented in force, inflammation would follow, and the excretion of urea nearly or entirely cease and life be in the greatest jeopardy. Alcohol: A Dangerous and Unnecessary Medicine, How and Why What Medical Writers Say The double salt of quinia and urea answers for this purpose, as it is very soluble in water and does not produce inflammation of the connective tissue. A System of Practical Medicine by American Authors, Vol. I Volume 1: Pathology and General Diseases 2012-03-17T02:00:54.097Z In effect the urea first becomes carbonate of ammonia by a simple hydrolysis brought about by bacteria, more and more definitely known since Pasteur, van Tieghem and Cohn first described them. Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 2 "Baconthorpe" to "Bankruptcy" Ultimately, the government plans to pay the subsidy directly to farmers, who will be able to buy products of their choice, including but not limited to urea. India's Green Revolution Wilts 2010-02-23T01:15:00Z These experiments may be held as demonstrating the fact that at least one organic compound of nitrogen is capable of being assimilated, as urea was actually identified as being present in the plants experimented with. Manures and the principles of manuring Uridrosis is a rare condition in which the sweat secretion contains the elements of the urine, especially urea. Essentials of Diseases of the Skin Including the Syphilodermata Arranged in the Form of Questions and Answers Prepared Especially for Students of Medicine Many salts are more soluble in a water solution of urea than in water alone, and many such mixtures are very hygroscopic. Northern Nut Growers Association Report of the Proceedings at the Thirty-Seventh Annual Report Wooster, Ohio, September 3, 4, 5, 1946 Nuts are free from waste products, uric acid, urea, and other tissue wastes which abound in meats. Northern Nut Growers Association Report of the Proceedings at the 13th Annual Meeting Rochester, N.Y. September, 7, 8 and 9, 1922 Mr. Awasti, the fertilizer cooperative head, says the continuing urea subsidy means that farmers likely will still use too much of it. India's Green Revolution Wilts 2010-02-23T01:15:00Z At any rate, as the plants were not tested for urea, the experiments must be regarded as leaving the problem unsolved. Manures and the principles of manuring The amount of urea excreted daily by a man is influenced by the activity of his mind, as well as by that of his body. The Stock-Feeder's Manual the chemistry of food in relation to the breeding and feeding of live stock The only contribution I have made is the use of urea in the solutions. Northern Nut Growers Association Report of the Proceedings at the Thirty-Seventh Annual Report Wooster, Ohio, September 3, 4, 5, 1946 This is due to the conversion of urea into carbonate of ammonia; and the same change takes place, though more slowly, with uric and hippuric acids. Elements of Agricultural Chemistry He says he believes that the urea subsidy will be dropped altogether in a year. India's Green Revolution Wilts 2010-02-23T01:15:00Z These are chiefly found in the urine, such as urea, uric and hippuric acids, and ammonia salts. Manures and the principles of manuring A human being whose mind is a perfect blank, and who performs no bodily work, excretes a large quantity of urea, the representative of an equivalent amount of worn-out flesh. The Stock-Feeder's Manual the chemistry of food in relation to the breeding and feeding of live stock In this latter variety of the disease, the urea is absent from the urine, and in its place is found more or less of sugar—often large quantities: Dunglison says 2½ oz. in a pint. A Newly Discovered System of Electrical Medication If these products are fully oxidized, however, they are thrown out in the form of the more soluble urea rather than as these acids. Special Report on Diseases of the Horse A last-minute compromise eliminated the subsidy on all fertilizers except for urea. India's Green Revolution Wilts 2010-02-23T01:15:00Z Laboratory experiments have also been carried out on such different nitrogenous substances as ethylamine, thiocyanates, gelatin, urea, asparagin, and albuminoids of milk. Manures and the principles of manuring The rabbit also throws off, or excretes, a fluid, the urine, which consists of water with a certain partially oxydised substance containing nitrogen, and called urea, and other less important salts. Text Book of Biology, Part 1: Vertebrata It is really a waste product formed by the activity of the body cells, and should properly be mainly transformed into urea and so excreted. Papers on Health The temperature throughout the disease is seldom increased, unless the disease becomes complicated with acute, inflammatory disease of the brain or respiratory organs, which often occur as a result of the urea in the circulation. Special Report on Diseases of the Horse "Without the urea, my crop looks sick," he said, picking up a few stalks of the young wheat crop and twirling them in his fingers. India's Green Revolution Wilts 2010-02-23T01:15:00Z They are partially oxidized, and the nitrogenous portion of the molecule is eliminated mainly in the form of amids, as urea. Human Foods and Their Nutritive Value Finally, the nitrogenous katastases, formed in the working of muscle and nerve, and returned by them to the blood for excretion, are not at that stage in the form of urea. Text Book of Biology, Part 1: Vertebrata These protein ashes and clinkers are further acted upon—split up and sifted—by the liver, and are finally eliminated by the kidneys in the form of urea, uric acid, etc. The Mother and Her Child These waste-stuffs, called urea and urates, are formed in the liver and brought in the blood to the kidneys. A Handbook of Health He said both the wheat and rice harvests should be bigger, considering that he's using so much more urea today than he did five years ago. India's Green Revolution Wilts 2010-02-23T01:15:00Z In calculating the available energy, correction is made for the unoxidized residue, as urea and allied forms. Human Foods and Their Nutritive Value The water of the urine is probably filtered off in the capsule, the urea and other salts secreted by the tubuli. Text Book of Biology, Part 1: Vertebrata They likewise do good for infantine colic, and they diminish the urea; when the urine contains it in excess. Herbal Simples Approved for Modern Uses of Cure Nuts are free from waste products, uric acid, urea, carmine and other tissue wastes. Northern Nut Growers Association, report of the proceedings at the eighth annual meeting Stamford, Connecticut, September 5 and 6, 1917 With urea selling for a fraction of the price of other fertilizers, farmers began using substantially more of the nitrogen-rich material than more expensive potassium and phosphorus products.

Physiology and Hygiene for Secondary Schools In the fowl, however, the blood-vessels of the allantois also probably absorb the albumen of the egg, and may excrete urea into the egg-space. Text Book of Biology, Part 1: Vertebrata In 1828 he made the remarkable discovery that when an aqueous solution of ammonium cyanate, CNONH4, is evaporated, the salt is completely transformed into urea, which has the same percentage composition. Scientific American Supplement, No. 365, December 30, 1882 The urine is usually scanty, of high specific gravity, rich in nitrogenous substances, especially urea and uric acid, and in calcium salts, while sodium chloride is deficient. Manual of Surgery Volume First: General Surgery. Sixth Edition. Adding urea doesn't have the effect it did in the past, he said, but it's so cheap that it's better than adding nothing at all. India's Green Revolution Wilts 2010-02-23T01:15:00Z The water leaves the body chiefly as a liquid, the urea as a solid dissolved in water, and the carbon dioxide as a gas. Physiology and Hygiene for Secondary Schools It gives off CO2, H2O, and urea, by the placenta, and it receives O and elaborated food material through the same organ. Text Book of Biology, Part 1: Vertebrata For pernicious forms: Hydrochlorate of quinine and urea ten to twenty grains, given hypodermically, every three or four hours until improvement occurs, when the sulphate of quinine by the mouth may be substituted. Mother's Remedies Over One Thousand Tried and Tested Remedies from Mothers of the United States and Canada In that case it is necessary to add an antacid such as urea to prevent its getting yellow or opaque. Creative Chemistry Descriptive of Recent Achievements in the Chemical Industries "One farmer sees another's field looking greener, so he adds more urea," he says. India's Green Revolution Wilts 2010-02-23T01:15:00Z They remove from the blood an exceedingly complex liquid, called the urine, the principal constituents of which are water, salts of different kinds, coloring matter, and urea. Physiology and Hygiene for Secondary Schools Besides this, it returns carbon dioxide and water, which are completely oxydised, and very simple and stable bodies, and urea-- a less completely oxydised compound, but a very simple one compared with the food constituents. Text Book of Biology, Part 1: Vertebrata This ash takes chiefly the form of a compound known as urea, which finds its way into the general circulatory system.

The Doctrine of Evolution Its Basis and Its Scope "A farmer will become bankrupt, but he will not stop using urea." India's Green Revolution Wilts 2010-02-23T01:15:00Z The muscles also have been suggested as a likely source of urea, for here the proteids are broken down in largest quantities; but the muscles produce little if any urea. Physiology and Hygiene for Secondary Schools In the capsules, water is drained from the blood; in the tubuli, urea and other salts in the urine are secreted from a branching network of vessels. Text Book of Biology, Part 1: Vertebrata The seizing of the urea by the kidney cell is a vital phenomenon which we must waive for the moment. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity Seventeen years elapsed between Wohler's discovery of the artificial production of urea and the next real synthesis, which was accomplished by Kolbe, when in 1845 he prepared acetic acid from its elements. Scientific American Supplement, No. 613, October 1, 1887 Leonard, of the United States, invented a powder consisting of 75 parts of nitro-glycerine, 25 parts of gun-cotton, 5 parts of lycopodium powder, and 4 parts of urea crystals dissolved in acetone. Nitro-Explosives: A Practical Treatise By the action of the liver cells these are converted into urea and this is turned back into the blood. Physiology and Hygiene for Secondary Schools By far the largest part of this waste nitrogen is expelled from the bodies of men and many other mammals in the form of urea. The Chemistry of Food and Nutrition For example, urea, formic acid, indigo, and many other bodies, hitherto produced only by animals and plants, were easily produced by the chemist by purely chemical methods. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity It breathes oxygen, and excretes carbonic acid and urea, through its whole body surface. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 As urea is converted into ammonium carbonate in the first stage of the action of the ferment, a supply of salifiable base would at first be present, but would gradually be consumed. Scientific American Supplement, No. 470, January 3, 1885 From the blood the urea is separated by the secreting cells of the kidneys. Physiology and Hygiene for Secondary Schools Pure urea is an odourless transparent crystalline substance, of cooling saline taste like nitre. The Chemistry of Food and Nutrition When the urea is stationary, which is most frequently the case, it is necessary to calculate the coefficient of oxidation; that is, the relation existing between the solid matters of the urine and the urea. Scientific American Supplement, No. 821, September 26, 1891 The fluid dropping from the ureter contained more urea than did the blood. Scientific American Supplement, No. 586, March 26, 1887 They also differ widely among themselves; compare, in this connection, serum albumen, acetic acid, cane sugar, urea. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 The liver is, first of all, a manufacturing organ, producing, as we have seen, three distinct products—bile, glycogen, and urea. Physiology and Hygiene for Secondary Schools In man, in addition to the urea excreted, there is also a little hippuric and uric acid or compounds of these. The Chemistry of Food and Nutrition Again, in order to recognize the exact variety of obesity, he divides his patients into three classes, each recognizable by the volume of urea excreted. Scientific American Supplement, No. 821, September 26, 1891 If to the famished blood was added one of the substances contained as ultimate products of digestion in the blood, such, for example, as urea, then did the secretion ensue. Scientific American Supplement, No. 586, March 26, 1887 Carlisle mentions a case in which there was vomiting of a fluid containing urea and having the sensible properties of urine. Anomalies and Curiosities of Medicine On account of the nature of the urea and the bile, the liver is properly classed as an excretory organ; but in the formation of the glycogen it plays the part of a storage organ. Physiology and Hygiene for Secondary Schools There is no obvious reason why some animals excrete urea and others uric acid. The Chemistry of Food and Nutrition In the first there is an increase above normal; in the second the volume of urea is stationary; in the third decreased, increased, or stationary. Scientific American Supplement, No. 821, September 26, 1891 In a similar manner, if yet not so intensely, operated saltpeter and coffeine, as also urea and pilocarpine. Scientific American Supplement, No. 586, March 26, 1887 Several cases have been reported in which the specific gravity of the urine was extremely high, due to an excess of urea. Anomalies and Curiosities of Medicine This consists chiefly of water, but contains a small per cent of salts and of urea.

The Chemistry of Food and Nutrition It can be made synthetically by heating together urea and glycocoll. The Gutenberg Webster's Unabridged Dictionary Section T, U, V, and W It was Wöhler who proved by the artificial preparation of urea from inorganic materials that this view could not be maintained. Scientific American Supplement, No. 362, December 9, 1882 These contain water, carbonic acid, urea, buturic acid, formic acid, acetic acid, salts, the chief being sodium chloride, and many other substances. Maintaining Health Formerly Health and Efficiency Researches have shown that alcohol increases the amount of uric acid in the body and decreases the amount of urea found in the urine. Physiology and Hygiene for Secondary Schools When the molecule is split up, and the carbon utilised, the nitrogen passes off in the form of urea by the kidneys. The Chemistry of Food and Nutrition It causes urea to take up water and decompose into carbonic acid and ammonia. The Gutenberg Webster's Unabridged Dictionary Section T, U, V, and W His contemporaries have not forgotten the unusual sensation produced by the unexpected discovery by which he was enabled to make artificially, and by a purely chemical method, urea, the most nitrogenous of animal substances. Scientific American Supplement, No. 362, December 9, 1882 Overeating of flesh is followed by excessive production of urea and uric acid products. Maintaining Health Formerly Health and Efficiency The conclusion to be drawn is that alcohol interferes in some way with the change of the harmful uric acid into the comparatively harmless urea—an interference which in some instances results in great harm. Physiology and Hygiene for Secondary Schools In the case of excretory glands the contrary will be the case, for their removal causes increase in the blood of the exciting urea and uric acid. Hormones and Heredity The nitrogenous end-products and aromatic compounds are urea, uric and hippuric acids, benzoic acid and ethereal sulfates of phenol and cresol. Common Diseases of Farm Animals This remedy was thought to convert uric acid into urea, and to so help elimination. Scientific American Supplement, No. 299, September 24, 1881 Some of these may be deposited in various parts of the body, while the urea is mostly excreted by the kidneys. Maintaining Health Formerly Health and Efficiency If one is in a weakened condition, the uric acid may fail to be oxidized to urea, as occurs normally, or to be thrown off as uric acid. Physiology and Hygiene for Secondary Schools The first combinations of these in animals are into what are called proximate principles, as albumen, fibrin, urea, alantoin, &c., out of which the structure of the animal body is composed.
