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 s...

background delayed onset muscle soreness (doms) is the sensation of stiffness and pain in the muscles that occurs 24-48 hours after unaccustomed or strenuous exercise. objectives the aim of this study was to examine and compare the effect of vibration training (vt) on delayed onset muscle soreness. materials and methods twenty healthy non-athletic volunteers (female, age 20-30 years, body mass ...

background: nicotine, cotinine and cadmium are harmful components of cigarettes that have an effect on human reproductive function. although the effects of cigarette smoke on male reproductive function is characterized in several articles its mechanism of action is still unknown. in the present study, we investigate the effect of nicotine, cotinine and cadmium on human sperm creatine kinase act...

Background: The aim of the present study was to investigate the in vitro effects of mercury (Hg+2), lead (Pb+2), silver (Ag+2), tin (Sn+2), bismuth (Bi+3) and indium (In+3) ions on sperm creatine kinase. Methods: creatine kinase was isolated from human sperm homogenates after chromatography on a DEAE cellulose column. Results: At 60 µg ml-1 metal concentration, 70% of the creatine kinase activi...

to improve the specificity of biochemical markers of myocardial infarction (mi) a method to measure cardiac troponin-i (ctn-i) was developed. ctn-i is a protein unique to cardiac muscle and is released after mi. consecutive 150 patients admitted to the coronary care unit was studied. value of ctn-i was determined in all samples. ctn-i concentration in the mi patients group was increased compare...

introduction: several mechanisms were introduced as causes of serum creatinine phosphokinase (cpk) raise in intoxicated patients. this study aimed to assess the relationship between serum cpk level in the first 24 hours and baseline characteristics as well as outcomes of these patients. methods: this one year retrospective cross-sectional study was conducted on all intoxicated patients, who wer...
