Endotheline-1 (ET-1) is a potent vasoconstrictor peptide with 21 amino acid residues. ET-1 is thought to have a key role in vasoconstriction, and cardiac, renal, and endocrine actions of the peptide. Creatine Kinase(CK), also referred to as ATP-creatine-N-phosphotransferase, consists of either the B or M type. CK is found almost exclusively in muscle(MM), myocardium(MB), and brain(BB). It is to be an almost specific index of injury of myocardium and brain in hypoxic damage. I measured the ET-1, CK isoenzyme in neonates among asphyxia group (14 cases), as a control devide into two group. 1st group(birth weight (2500 g, n=9) and 2nd group (body weight 2500g, n=11). 1) There was no significant difference between asphyxia and control 1st, 2nd group during postnatal 24 hrs include cord blood on irET-1(p< 0.05). 2) There was significant difference between asphyxia and control 1 st, 2nd group during postnatal 24 hrs include cord blood on CK and CK and CK isoenzyme (p<0.001). 3) There was significant difference between asphyxia and control 1st, 2nd group on CK-MB and CK-BB proportion (p< 0.001). 4) There was significant difference between cord blood and postnatal 24 hrs on total CK level (P< 0.001).

OBJECTIVE:
To study the changes of serum creatinine kinase(CK) and its cardiac-specific isoenzyme compound(CK-MB) levels in crush injury rats.
METHODS:

RESULTS:
The levels of plasma CK and CK-MB were much higher in crush injury rats than those of the control group.
CONCLUSIONS
Cardiomyocyte injury may be induced in the early stage of crush injury rats.

To evaluate effect of coronary collateral circulation on left ventricular function in patients with acute myocardial infarction, global ejection fraction(EF), left ventricular end distolic pressure(LVEDP), peak creatine kinase(CK) level and regional wall motion were analysed and compared in 30 patients with acute myocardial infarction according to grade of coronary collateral circulation. Patients with total or near total(above 95% of diameter) occlsion of left anterior descending coronary artery without significant lesion in right coronary artery or left circumflex artery were selected and divided into 3 groups according to the degree of collateral circulation on coronary angiography, to be compared by the index of ejection fraction, peak creatine kinase level, left ventricular and diastolic pressure and regional wall motion. The result are as following : 1) There were no statistically significant differences in ejection fraction, peak creatine kinase level, left ventricualr and diastolic pressure among the groups. 2) Regional wall motion of infarct related area of G2+3 group(adequate collateral) were better than that of G0(no collateral) group(p<0.05). Therefore, adequate coronary collateral circulation in acute myocardial infarction is thought to have beneficial effect on left ventricular function especially in regional wall motion of infarct related area.

BACKGROUND: We hypothesized that, even in patients taking aspirin, the variance of preoperative platelet response to collagen might be associated with myocardial injury during coronary artery bypass graft (CABG) surgery. Therefore, we evaluated the relationship between preoperative whole-blood aggregometry (WBA) by collagen and the postoperative myocardial injuries. METHODS: For 44 patients who were scheduled for elective off-pump CABG and taking aspirin, WBA was measured by the impedance method in the presence of collagen (2 mg/ml or 5 mg/ml) as stimulatory agents. After CABG, myocardial injury was evaluated by analysis of the creatine kinase (CK), creatine kinase-MB (CK-MB), and lactate dehydrogenase (LD), and by electrocardiography. RESULTS: High response group (n = 13) on preoperative WBA with collagen (2 and 5 mg/ml) showed significantly higher postoperative cardiac enzyme levels (CK, CK-MB and LD) than those of low response group (n = 31). CONCLUSIONS: In patients who take aspirin and undergoing off-pump CABG, the preoperative platelet response to collagen is correlated with postoperative myocardial injury.

OBJECTIVETo study the dynamic changes of serum CK, CK-MB and myocardium histomorphology in different time periods after single bout and repeated exhausted exercise in rats.
METHODSThe animal models of myocardial injury were established by exhausted swimming. Creatine kinase (CK), creatine kinase mass (CK-MB) activities in serum were measured immediately at 3, 6, 12, 24, 48 and 96 hours after exhausted exercise, and the dynamic changes of myocardial histopathology were examined.
RESULTSThe CK, CK-MB activities were significantly increased immediately at 3, 6, 12 hours and peaked at 6 hours after single bout of exhausted exercise, meantime the degree of inflammatory cell infiltrate and strong acidophil staining were gradually increased in myocardium of rat, and the myocardial injury was most severe at 12 hours. After 1-week consecutive daily exhausted swimming, CK, CK-MB in serum were obviously increased immediately at, 3, 6, 12, 48 and 96 hours postexercise and peaked immediately and at 96 hours respectively postexercise. There were different degrees of myocardial injury in different time of recovery phase, and was most severe at 48 hours postexercise.
CONCLUSIONThe myocardial injury was induced by excessive exercise and/or exhausted exercise, and the resulting delayed-onset myocardial injury was further certified.

9.Oligosaccharide and creatine supplementation on glucose and urea nitrogen in blood and serum creatine kinase in basketball athletes.
Journal of Huazhong University of Science and Technology (Medical Sciences) 2005;25(5):587-9
The effects of oligosaccharide and creatine (Cr) supplementation on glucose, lactic acid and urea nitrogen levels in blood and activity of serum creatine kinase (CK) were explored. Twenty CUBA male athletes were divided into 4 groups: group A (supplementation of Cr alone), group B (supplementation of oligosaccharide), group C (supplementation of oligosaccharide and Cr) and group D (placebo control group). By using orthogonal L4 table (2(3)), the experiment was performed. There were factors including oligosaccharide (carbohydrate, CHO), Cr and their correlation. Each factor had two levels: supplementation and no-supplementation. The results showed that the supplementation of CHO or Cr alone, combined supplementation of CHO and Cr could significantly reduce the glucose, urea nitrogen levels in blood and serum CK activity after competition in the athletes. Moreover, the effects of combined supplementation of CHO and Cr were more satisfactory. It was concluded that supplementation of CHO and Cr could promote the recovery of physical performance and athletic abilities after athletics in basketball athletes.
