Colorimetric Determination of Serum
In the past few years there has been renewed interest in the study of serum cholinesterase in various disease states, particularly those affecting the liver. Recently, a colorimetric method for the determination of this enzyme in the serum was reported by Ravin, Tsou, and Seligman (1). Their method, simple to perform, is as accurate as the gastrometric technique and more specific than the elect...
متن کاملprediction of dissolved oxygen through mathematical modeling
water quality aspect with regard to dissolved oxygen was studied for a 24 kilometer stretch of malaprabha river in karnataka state, india. main objective of the research was to simulate the predicted dissolved oxygen depletion due to the waste load allocation in the river with the ambient observed values of dissolved oxygen, and to ascertain the application of mathematical modeling for predicti...
متن کاملcharacteristics and seasonal variations of dissolved oxygen
large amounts of degradable wastes including sewage water and agricultural waste or nutrients that stimulate growth of organic matter are discharged into the caspian sea. as a result, average dissolved oxygen concentration in deeper layers is decreasing. this paper presents distribution and seasonal variations of the concentration of dissolved oxygen over the southern shelf of the caspian sea a...
متن کاملColorimetric determination of blood arginase.
N EXTENSIVE LITERATURE Ofl arginase activity in tissues and tissue homogenates has accumulated in recent years. Roberts (1) has studied the arginase activity of liver, kidney, and epidermis of the Swiss mouse and of a transplantable squamous cell carcinoma. He found that liver had the greatest activity, followed by carcinoma, epidermis, and kidney. Sano (2) isolated an enzyme from rabbit intest...
متن کاملColorimetric determination of blood lipides.
Extraction-As the oxidation is essentially non-specific, the plasma extract must be as free of non-lipide reducing substances as possible. All solvents should be tested occasionally for reducing residues remaining after evaporation, and redistilled if necessary. Ether should be maintained peroxide-free. The determinations reported here followed a conventional alcohol-ether extraction and subseq...
