Ehrlich has used a double stain with neutral red and methylene blue.
This method, however, cannot pass as entirely free from error, as Ehrlich frequently found that when the experiment lasts some time the methylene blue often forms granular precipitates that may be confused with the granules.
This perhaps depends on the peculiarities of the case, or on the uncertainty of the staining method: eosine-methylene blue stain, which is for this purpose very unreliable, since slight overstaining towards blue readily occurs.
Glucose will reduce methylene blue in alkaline (not in neutral solution), but luciferin will not reduce methylene blue in alkaline or neutral solution.
Methylene blue can be reduced by the H{2} and the hypophosphite oxidized.
Just as in the case of methylene blue the reaction proceeds in the right hand direction spontaneously if the pressure of O is sufficiently high.
Oxyluciferin is not reduced by palladium alone or hypophosphite alone, butmethylene blue is reduced by palladium black alone.
I believe the change which occurs when luciferin is oxidized is similar to that which occurs when the leuco-base of methylene blue or sodium indigo-sulphonate is oxidized to the blue dye.
This may be due to the fact that oxyluciferin, which is also present, may be reduced more readily than either nitrates or methylene blue, and so is reduced first.
While this may be due to the development of bacteria with a reducing action, it does not seem likely, as under the same conditions methyleneblue is not reduced in 24 hours, and there is no turbidity or smell of decomposition in the tube.
As we shall see, it is probably similar to the oxidation of reduced haemoglobin or the oxidation of leuco methylene-blue to methylene blue.
According to Barthel, milks that reduce the methylene blue within fifteen minutes contain hundreds of thousands of bacteria per cubic centimeter.
The reduction test is made by adding to twenty cubic centimeters of milk, one-half cubic centimeter of a solution of methylene blue, a coal tar dye.
The bacteria on this plate are partly from tissues, partly from cultures, and stained artificially with aniline colors (fuchsin ormethylene blue).
Quinin, arsenic, methylene blue, and other drugs have been used, but without success.
The larger body on the right b is a white blood corpuscle, also stained with methylene blue.
The Texas-fever microbes a are shown as pear-shaped bodies, stained with methylene blue, within the red corpuscles.
Various medicinal agents, such as carbolic acid administered subcutaneously and methylene blue fed in large quantities, have been recommended, but have failed to stand the tests of scientific investigation and practical use.
The benzene readily evaporates spontaneously from the methylene iodide, and the water can be driven off from the diluted thallium silver nitrate by boiling.
The nitrate might be used by itself to include the whole series, but it is more convenient to use the methylene iodide when possible, both because it can be employed at ordinary temperatures and because it is cheaper than the nitrate.
But methyleneiodide further possesses the valuable property of mixing easily with benzene, which is a very light liquid.
Taken, then, a liquid which is heavy--the most convenient is methylene iodide, whose specific gravity is 3.
Yeast is capable of producing many vigorous reducing actions and rapidly reduces methylene blue and sodium selenite.
In the absence of sugar on the other hand an excess of carbon dioxide equimolecular to the methylene blue is evolved but no corresponding increase in the alcohol production occurs.
On the whole it cannot be said that the evidence gathered from experiments on the reduction of acetaldehyde and methylene blue is very convincing.
In presence of sugar the methylene blue causes a decrease in the extent of fermentation, the difference during the time required for reduction of the methylene blue being represented by an amount of glucose equimolecular to the latter.
This particular discoloration, greenish in color, is the result of the work of the drugmethylene blue in contact with formaldehyde.
This greenness is more pronounced when chemicals such as methylene blue have been administered by the attending physician before death.
There is a chemical action set up between the formaldehyde and the methylene blue, which gives the tissues a greenish color, which is quite objectionable.
A good formula to use, when you know methylene blue has been used by the attending physician is: Rx Carbolic acid 5 oz.
If methylene blue has been administered by the attending physician and you have learned this fact before hand, it is then not advisable to use a formaldehyde fluid.
There is a chemical action set up between the methylene blue and the formaldehyde which will give to the tissues a greenish color which is quite objectionable.
The condensation product gives a slight precipitate with gelatine, and a bluish-grey precipitate with ferric chloride; acids re-precipitate the insoluble methylene compound.
Thus when nitrobenzene is reduced by iron and an acid we get aniline; similarly when nitrosodimethylaniline is reduced by zinc and an acid we get amidodimethylaniline, and this is the base used in the preparation of methylene blue.
By the action of nitrous acid the blue is converted into a green known as "methylene green.
The micro-organism of tubercle, for example, was in this way found by Koch to be readily stained by methylene blue, and its detection was thus rendered possible with certainty.
Instead of using the diamidobenzene, Caro used its dimethyl-derivative, and by this means obtained a splendid blue dye, which was introduced under the name of "methylene blue.
Thus, if we take a solution of pure methylene iodide, which has a specific gravity of 3.
A marked increase in the time required for the sperm to reduce methylene blue occurred when the glycerol was added (Table 17).
The effects of various freezing procedures on the ability of samples to decolorize methylene blue were determined with 10 semen samples.
Freezing and storage of semen resulted in slower reduction of the methylene blue than was shown after equilibration with glycerol.
Following equilibration, the samples regained the ability to reduce methylene blue at a rate only slightly slower than when they were fresh.
The anaesthetics which have hitherto been employed in the practice of medicine are chloroform, sulphuric ether (or a mixture of these), bichloride of methylene and nitrous oxide, and amylene.
Chloride ofmethylene is a colourless mobile fluid, having a smell like chloroform, and a burning taste.
Dr Richardson says of this latter it is not so quick in its action as the methylene chloride, but that it is safer.
Beige, Methylene Blue, Curcumine and Fast Brown, mixed according to tone and shade.
To this purpose a cold bath is prepared with only so much methyl violet or methylene blue, as to give the water a very faint tint.
If, on the other hand, a direct blue is topped with methylene blue, its brilliancy may be enhanced.
Methyl Violet, Auramine and Methylene Blue, because of their special physiological action.
Thus by dyeing cotton first yellow in chrysamine and then dyeing it again in a cold bath of methylene blue a brilliant shade of green results.
Neisser's method of staining failed to give such good effects by the examination of fresh maya, as did an alcoholic aqueous solution of methylene blue in showing up the granules of the organisms.
It differs from the above by showing peculiar pink-stained granules, when stained with methylene blue and showing peculiarly convoluted chains in glucose agar.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "methylene" in a variety of sentences. We hope that you will now be able to make sentences using this word.
