The aims were to assess (a) the usefulness of RESTQ-Sport in the process of training monitoring and (b) whether a change in psychological parameters is refl ected by similar changes in specifi c biochemical parameters. The high volume training period, in general, caused increases in stress scales and decreases in recovery scales of the RESTQ-Sport, while during recovery period, stress levels de...

Direct assay of creatine kinase by the method of Siegel and Cohen with the Technicon “SMA 12/60” is compared with two indirect coupled-enzyme assay methods. The direct method was linear to greater than 2000 U/liter, whereas the indirect methods were linear to 250 and 1500 U/liter, with use of serial dilutions of a creatine kinase preparation. Increasing the activity of the auxiliary enzymes, he...

A programme was introduced in Wales to screen all 18 month old boys who were not yet walking for raised creatine kinase activity within the existing community developmental screening programme. During an 18 month period 25 229 such boys were identified of whom 19 930 (79%) had a Denver developmental screening test and 338 (1.7%) of these were not walking. Two hundred and five of those who did n...

Higher levels of total serum creatine kinase activity have been reported in black compared with white North Americans of the same sex. In a study among South Africans, we found such an interracial difference was notable only for males. The difference was heightened by physical activity. This study affirms the importance of sampling the indigenous population when developing a reference range for...

Members of three unrelated families with the mild Becker type of muscular dystrophy were subjected to lymphocyte capping tests and measurements of serum creatine kinase activity. Both tests correctly identified all nine affected males, but only the capping test was abnormal in seven of eight obligate carriers. The number of capped cells in carriers and affected persons with the Becker-type dyst...

Twenty patients’ serums have been analyzed by both the Sax-Moore (1) and ConnAnido (2) creatine kinase methods. No significant difference in enzyme activity was found. In our hands, the Conn-Anido procedure, as originally described, gave variable results and high background fluorescence. The presence of high alkaline or acid phosphataseactivities in specimensanalyzed by the Sax-Moore procedure ...

2120 CLINICAL CHEMISTRY, Vol. 40, No. 11, 1994 we reported here, we overcome this problem by using the filters. We have not observed any late-eluting peaks that would interfere with the subsequent chromatogram nor any reduction in column life attributable to sample contamination. Moreover, the results we obtained with the amperometric detector are comparable with those of the coulometric detector.

Serum enzyme studies were made on 43 (37 male, 6 female) consecutive patients with ankylosing spondylitis. Serum creatine phosphokinase (CPK) activity was raised above 55 IU/l in 24 (65%) of 37 male patients (range 29-165 IU/l, mean 68) as compared with 2 (4%) out of 47 male controls (range 14-85 IU/l, mean 33: P less than 0-001); levels were greater than 35 IU/l in six (100%) out of six female...
