laboratory procedure on the determination of mannitol content from blood and urine of rabbit?
925236
The determination of urinary lactulose and mannitol is usually done by gas-liquid chromatography.  Other methods usually have a much higher errors.\n\nClassical methods like that of A. C. Corcoran and Irvine H. Page (from 1947) are very poor, but could be used for a high school science fair project.  They are no longer suitable for contemporary research.\n\nRecent enzymatic methods look promising, as do High-Performance Anion-Exchange Chromatography with Pulsed Amperometric Detection.

blood tests. Creatinine and BUN (blood urea nitrogen). These are byproducts of kidney waste. If they are too high your kidney is not excreting them well enough, I'm a nurse

Additional information is needed.  The mixture could contain one atom of Potassium and the rest Sodium or the reverse.\n\nThe total mass of the sample does not tell you anything about the relative mix.

The amount of some materials in the sample can be changed by chemical reactions, including those that occur inside cells.  The rate of many chemical reactions is decreased by lowering the temperature.\n\nFor example, blood for "blood gases" is placed on ice, and rushed to the lab.  There, it is injected, from the original syringe, into the testing machine.  One of the analytes is oxygen; the loss or gain of oxygen must be minimised.  Thus, the cells are chilled; WBC use oxygen.  The blood is not decanted from the syringe into a tube, for transport, as it may equilibrate with air.\n\nCooling also reduces changes in pH of the blood, which would otherwise result from metabolism, including that of the RBC.\n\nIn general, it slows the rate of change of the sample, so values from tests reflect what was going on in the patient, at the time it was taken.

Fehlings solution is used to test for sugar.  Try a diabetic dipstick.

i suggest u get your renal function tests done along with other routine investigations like blood sugar.Renal fn. tests include serum creatinine,BUN,sodium and patassium.

I wouldn't think so since blood agar is already a semi-solid. A coagulase test really should be done to a liquid to see if it turns into a semi-solid.

You can work on fruit juices and other beverages like colas etc..carry out small analysis to find out how many of them contain glucose/sucrose ie aldoses and ketoses..u can also determine if they contain carboxylic acids,ascorbic acid etc.u can do benedicts/fehling test and lucas test on the different juices.can determine if any kind of OH group is present in those drinks..wt vitamins,wt minerals present.\nA similar kind of study can be done on toothpastes..take different brands of toothpastes,carry out tests on them as which ones contain Flouride,bleach,whitening powders and whiche all contains sugar.

Preparative HPLC should do the trick.  Try a search at these to see if an exact procedure might be on the web.\n\n\nhttp://www.scienceresearch.com/search/\n\nhttp://www.scirus.com/srsapp/

Along the loops of Henle within the kidney, the concentration gradient ranges from 300 - 1200 mosmol.  1200 mosmol occurs at the bottom of the loop.\n\nEverything you ever wanted to know:\nhttp://www.biol.sc.edu/courses/bio102/f99-44.html\n\nGood luck!

From this patent\n\nwww.freepatentsonline.com/6962719.html\n\n\n\nThe total extract described in EXAMPLE 1 was loaded in a dialysis bag with molecular weight cut off 500 (Spectra/Por®, Cat. No. 131 057). Both ends of the bag were sealed with clamps. The bag was placed in a bucket contained deionized water, in which the ratio of the supernatant and deionized water was 1:10. The total extract was dialyzed at 4° C. with stirring thrice each for 20 hours. The solution remaining in dialysis bag was collected and concentrated under reduced pressure to give the extract.

Just curiosity: given by a boyfriend or girlfirend?\nAlso how old are you both. Then I will be able to give some answer about safety.\n\nOf course, you have no lab to make analysis what is really in it...

As no one else has had a go, i will. \n\nCellulase should produce glucose, so you are needing a method to analyse the amount of glucose formed. \n\nIf you have access to a blood glucose monitor, this would be the simplest way. Otherwise, the reaction between glucose and Benedicts solution is quantitative, and you could weigh the amount of Cu2O formed.

380nm is a good wavelength to detect any mammal fluids.\n\nBut you don't have to look for a particular wavelength. All "ultraviolet urine detectors" on the net will do the trick, even if they were originally designed for cats and dogs (urine is urine!).\n\nSee for instance http://www.arcatapet.com/item.cfm?cat=7162

There is a liquid that can be used to test your tester and test strips.  You put a dot of it on your strip and then use the meter and it should read 100.  I can't remember the name of the stuff but you can pick it up at any drug store ask the pharmacist.  If the reading is correct then you know the strips are still good.\n\nOtherwise I wouldn't risk it more than a month past because you don't want to be wrong about you levels.  \n\nIf I can find my husbands I will modify my answer or email you with the name.

Right after the donation the blood components are separated into Platelets ( good for 5 days), Plasma ( frozen good for 1year) and red blood cells ( good for 30 days). The testing is done on the extra tubes taking during donation. Testing is done for some chemistry, infectious disease ( HIV, west Nile, Hepatitis B, C, and many more). The blood is typed (A,B,AB,O and RH+/-). It is also tested for poss. bacteria contamination. A complete blood count is performed. After all the test pass acceptability, the components are released to be given. All components are constantly monitored regarding the storage temp.\nBefore blood components are given the recipient is tested to be compatible to the product. ( same blood type and compatible cross match with the donor).\nThe is a lot of checking and double checking involved in blood banking. If you need more or specific info just e-mail me.\nbeen working in blood bank for 20+ years.
