New 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...

A colorimetric method for the estimation of acetoacetic acid in the blood.

It was observed that acetoacetic acid when coupled with 4-nitrobenzenediazonium salt in a buffered carbonate solution yielded a strong green color upon further alkalization. This reaction was given by relatively few of the biochemical compounds that have been tested, and the procedure has been developed so that, as applied to blood filtrates, it is believed t,o afford a. satisfactory measure of...

A Micro Colorimetric Method for the Quan- Titative Estimation of Iodine in Blood

Various investigators have reported on methods for the estimation of iodine in air, food, water, vegetables, tissue, and blood. Chatin (1) in 1851 used the method of Rabourdin (2) and established the presence of iodine in air. Rabourdin’s method depends on converting the iodine to potassium iodide, setting it free with nitrous acid, and extracting with carbon disulfide. Detection was possible i...
