Creatine and creatine kinase measurement.
*Many methods for measuring creatine are known, the principal ones being direct calorimetric assay (l), indirect calorimetric assay (2), and destruction with bacterial adaptive enzymes (3). However, none of these methods are specific nor are they sensitive enough to detect very small amounts of creatine. rIhese assays have been used to examine urine and serum for creatine content, but, because ...
متن کاملMuscle creatine uptake and creatine transporter expression in response to creatine supplementation and depletion.
The total creatine pool size [Cr(total); creatine (Cr) + phosphocreatine (PCr)] is crucial for optimal energy utilization in skeletal muscle, especially at the onset of exercise and during intense contractions. The Cr(total) likely is controlled by long-term modulation of Cr uptake via the sodium-dependent Cr transporter (CrT). To test this hypothesis, adult male Sprague-Dawley rats were fed 1%...
متن کامل748 Creatine Kinase and Creatine Phosphate in Macrophages
Creatine phosphate serves as a reuseable high energy phosphate reservoir in skeletal and cardiac muscle and in the brain. These stores of creatine phosphate are thought to rephosphorylate the ATP hydrolyzed during cellular work (see 1 and 2 for review). Studies in our laboratory (3) have shown that mononuclear phagocytes obtained from the peritoneal cavities of mice also contain large stores of...
متن کاملCreatine supplementation in COPD
M ultidisciplinary pulmonary rehabilitation now has an established place in the management of chronic disabling respiratory diseases, particularly chronic obstructive pulmonary disease (COPD). Rehabilitation is being taken up widely on the strength of the accumulated evidence. While the effectiveness of rehabilitation is accepted, there is still considerable interest in refining and researching...
متن کاملNOVEL REAGENTS FOR CREATINE KINASE
The purpose of this investigation was to develop a simple colorimetric method for creatine kinase (CK). The new method is based on the reaction of creatine, formed enzymatically from creatine phosphate and ADP, with different glyoxal compounds. Hydrated glyoxals, such as para-nitrophenyl, 2-thiophene, 4- biphenyl, 4, 4' -biphenyl,α-naphthyl, β-naphthyl, para-chlorophenyl, and styryl were...
