Colorimetric method for rapid determination of bacteriuria.
An inexpensive, rapid, and simple colorimetric test for detection of bacteriuria is described. This test does not require bacterial growth and has the marked advantage of being able to quantify bacteria, even when the organisms are present in the urine of bacteriuric patients who are being treated with antibiotics. The test is carried out with 1 ml of urine, which is processed through a 10-mm-d...
متن کاملColorimetric method for rapid determination of serum arginase.
A method for the determination of serum arginase is given which combines the enzymatic formation of urea with the sensitive method of Coulombe (1) for measuring this substance. This procedure allows more accurate determinations in the normal range than do previous methods described and is convenient for clinical routine. Significant difference is found between the mean values of normal men and ...

15 صفحه اولEvaluation of cotton fibers stickiness by colorimetric method
Stickiness is the physical process of contaminated lint adhering to equipment. The degree of stickiness depends on chemical identity, quantity, and distribution of the sugars. The sugar in cotton fibers may be insect or plant derived. There are several methods for measuring cotton fibers stickiness. In this work, a colorimetric method was used for the measurements. In the method, honeydew was c...
متن کاملNew Enzymatic Colorimetric Method for the Quantitative Determination of Phenylalanine in Dry-Blood Spots
Phenylketonuria (PKU) is an autosomal recessive disorder, which is characterized by severe mental retardation, microcephaly and seizures. The symptoms of this disease can be prevented if detected soon after birth. Therefore, blood Phenylalanine (Phe) measurement is essential for the early diagnosis, treatment and dietary monitoring of PKU patients. The goal of this research was to introduce a r...
