In this report, we introduce a new physiological model of the serum creatine phosphokinase (CPK) activity change, that is useful for estimating the total CPK release accurately even with reduced blood sampling frequency. The physiological model was applied to the serum creatine kinase CPK activity change of patients who suffered acute myocardial infarction (AMI), and the model showed good agreement with the serum CPK activity. In addition, the calculated value of total CPK release agreed well with that calculated using the conventional technique ...
1. The dose of pentobarbitone required for anaesthesia was significantly greater for dystrophic hamsters than for normal animals.. 2. Serum creatine kinase activity was significantly higher in dystrophic than in normal hamsters.. 3. Brain, heart and tibialis anterior muscle from dystrophic animals contained significantly less creatine kinase than the normal tissues.. 4. Creatine kinase in normal and dystrophic sera, as in skeletal muscles, consisted of MM isoenzyme. Heart creatine kinase consisted of both MM and MB types and brain contained only the BB isoenzyme.. 5. Pentobarbitone raised serum creatine kinase activity of normal and dystrophic hamsters to the same extent, elevation of enzyme activity being dependent on the amount of pentobarbitone injected.. 6. The sera of pentobarbitone-treated normal and dystrophic hamsters contained only the MM isoenzyme.. ...

INTRODUCTION. Trauma of diverse origins is a common reason for presentation of pets for treatment. It is often difficult clinically to objectively quantify the severity of any trauma suffered by an animal. One approach is to measure changes in the various serum constituents that are known to alter in response to trauma or inflammation. Creatine kinase (CK) is an enzyme found predominantly in skeletal muscle and significantly elevated serum activity is largely associated with muscle damage. It is an extremely sensitive indicator of muscle damage, but is not specific as to cause14,27. Serum elevations in dogs are associated with cell membrane leakage and will therefore be seen in any condition associated with muscular inflammation, necrosis or degeneration. Peak serum activity is expected between 3 and 12 hours after muscular insult and the elevation is roughly proportional to the amount of muscle tissue involved1,5,27.It is also possible to quantify the mass of muscle damage if the changes in CK ...

Hypertension remains the main risk factor for cardiovascular death. Environmental and biological factors are known to contribute to the condition, and circulating creatine kinase was reported to be the main predictor of blood pressure in the general population. This was proposed to be because of high resistance artery creatine kinase-BB rapidly regenerating ATP for vascular contractility. Therefore, we assessed whether creatine kinase isoenzyme mRNA levels in human resistance arteries are associated with blood pressure. We isolated resistance-sized arteries from omental fat donated by consecutive women undergoing uterine fibroid surgery. Blood pressure was measured in the sitting position. Vessels of 13 women were included, 6 normotensive and 7 hypertensive, mean age 42.9 years (SE, 1.6) and mean systolic/diastolic blood pressure, 144.8 (8.0)/86.5 (4.3) mm Hg. Arteriolar creatine kinase isoenzyme mRNA was assessed using quantitative real-time polymerase chain reaction. Normalized creatine kinase ...
FEIER, Gustavo et al. Creatine kinase levels in patients with bipolar disorder: depressive, manic, and euthymic phases. Rev. Bras. Psiquiatr. [online]. 2011, vol.33, n.2, pp.171-175. Epub Mar 18, 2011. ISSN 1516-4446. http://dx.doi.org/10.1590/S1516-44462011005000005.. OBJECTIVE: Bipolar disorder is a severe, recurrent, and often chronic psychiatric illness associated with significant functional impairment, morbidity, and mortality. Creatine kinase is an important enzyme, particularly for cells with high and fluctuating energy requirements, such as neurons, and is a potential marker of brain injury. The aim of the present study was to compare serum creatine kinase levels between bipolar disorder patients, in the various phases (depressive, manic, and euthymic), and healthy volunteers. METHOD: Forty-eight bipolar patients were recruited: 18 in the euthymic phase; 17 in the manic phase; and 13 in the depressive phase. The control group comprised 41 healthy volunteers. The phases of bipolar ...

In the dog, creatine kinase (CK) is mostly present in the skeletal muscles, myocardium, brain and intestine. The MM isoenzyme predominates in muscles and myocardium. In plasma, reference values depend on the technique used and CK-MB accounts for about 30-45% of total CK activity. Sex has no influence on plasma CK activity, which is higher in young dogs than in adults. Plasma CK is elevated after physical exercise. After its release from the cells, CK reaches the plasma mostly via the lymphatic route and then remains in the plasma compartment. It is rapidly cleared with a half-life of about 2 hours. Muscle diseases are the main source of plasma CK elevations: inherited myopathies, malignant hyperthermia, hypothyroidism, vitamin E-selenium deficiency, prolonged decubitus, intramuscular injections, surgery, etc. Plasma CK is also increased in experimental myocardial infarction, for which the dog is an interesting model, allowing quantification of the damage by measuring the total CK activity ...

Creatine kinase (CK) isoenzymes are essential for storing, buffering and intracellular transport of "energy-rich" phosphate compounds in tissues with fluctuating high energy demand such as muscle, brain and other tissues and cells where Creatine Kinase CK is expressed. Using dividing HeLa cells, we report here for the first time that GM130 and Creatine Kinase BB isoenzyme BB-CK co-localize specifically in a transient fashion during early prophase of mitosis, when GM130 plays an important role in Golgi fragmentation that starts also at early prophase. These data may shed new light on CK BB Isoenzyme BB-CK function for energy provision for Golgi-fragmentation that is initiated by cell signalling cascades in the early phases of mitosis. source ...
Chicken heart muscle contains almost exclusively the BB isoenzyme of creatine kinase (CK), its myofibrils, moreover, lack an M-line. This tissue thus provides an interesting contrast to skeletal muscle, in which some of the MM-CK present as predominant CK isoenzyme is bound at the myofibrillar M-line. Approx. 2% of the total CK activity in a chicken heart homogenate remains bound to the myofibrillar fraction after repeated washing cycles; both the fraction and the absolute amount of CK bound are about threefold lower than in skeletal muscle. Almost all of the bound enzyme is located within the Z-line region of each sarcomere, as revealed by indirect fluorescent-antibody staining with antiserum against purified chicken BB-CK. After incubation with exogenous purified MM-CK, positive immunofluorescent staining for M-type CK at the H-region of heart myofibrils was observed, along with weaker fluorescence in the Z-line region. Chicken heart myofibrils may thus possess binding sites for both M and B ...
Creatine phosphokinase (CK) isoenzymes are found in various tissues, such as skeletal muscle (CK-MM), cardiac muscle (CK-MB), and the brain (CK-BB). Elevated CK isoenzymes indicate damage or injury to specific tissue. Using CK isoenzymes as a marker in order to indicate muscle damage as a result of different degrees of resistance exercise has not been clearly examined. Purpose: To determine the changes in CK isoenzymes following resistance exercise at different intensities. Methods: Ten healthy recreationally resistance-trained (at least 3 - 6 days per week for a minimum of one year) men participated in the study. The participants performed a lower body resistance exercise, composed of leg press and unilateral knee extension, at two different intensities (low: 50% of 1-RM and high: 80% of 1-RM) in random order. The volume of two intensities was similar. Overnight fasting serum samples were collected at baseline and 3-hr, 24-hr, and 48-hr post exercise for each intensity to determine CK-MM, CK-MB, and CK
OBJECTIVE--To determine whether transient ST-T alterations in patients with unstable angina are associated with an increase in plasma glycogen phosphorylase BB concentrations on admission to hospital. DESIGN--Prospective screening of patients with unstable angina for markers of myocardial cell damage. SETTING--Accident and emergency department of university hospital. PATIENTS--48 consecutive patients admitted for angina pectoris (18 with transient ST-T alterations). None of the patients had acute myocardial infarction according to standard criteria. MAIN OUTCOME MEASURES--Creatine kinase and creatine kinase MB activities, creatine kinase MB mass concentration, and myoglobin, cardiac troponin T, and glycogen phosphorylase BB concentrations on admission. RESULTS--All variables except for creatine kinase and creatine kinase MB activities were significantly higher on admission in patients with unstable angina and transient ST-T alterations than in patients without. However, glycogen phosphorylase BB ...

Background. We investigated the effects of short vs. long length of rectus femoris during eccentric exercise of similar range of motion on selected muscle damage indicators. Methods. Using all isokinetic dynamometer at 1.05 rad/s, 12 healthy male [mean (standard deviation), 21 (2) years] volunteers randomly underwent two exercise sessions, one on each leg, 14 days apart. During each session, subjects had to accomplish 12 sets of 10 maximal voluntary efforts in seated and prone positions to achieve short and long length of rectus femoris, respectively. Muscle damage indicators [serum creatine kinase activity, delayed onset muscle soreness, range of motion, eccentric peak torque, concentric peak torque and isometric peak torque] were assessed pre-exercise and 24, 48, 72 as well as 96 h post-exercise. Findings. Compared to baseline data, creatine kinase, delayed onset muscle soreness, and range of motion disclosed significant changes at all time points after both exercise sessions (P , 0.05). ...
The mitochondrial creatine kinase (CKm) is present in the mitochondrial intermembrane space, where it regenerates phosphocreatine (PCr) from mitochondrially generated ATP and creatine (Cr) imported from the cytosol. Apart from the two mitochondrial CK isoenzyme forms, that is, ubiquitous mtCK (present in non-muscle tissues) and sarcomeric mtCK (present in sarcomeric muscle), there are three cytosolic CK isoforms present in the cytosol, depending on the tissue. Whereas MM-CK is expressed in sarcomeric muscle, that is, skeletal and cardiac muscle, MB-CK is expressed in cardiac muscle, and BB-CK is expressed in smooth muscle and in most non-muscle tissues. Mitochondrial mtCK and cytosolic CK are connected in a so-called PCr/Cr-shuttle or circuit. PCr generated by mtCK in mitochondria is shuttled to cytosolic CK that is coupled to ATP-dependent processes, e.g. ATPases, such as acto-myosin ATPase and calcium ATPase involved in muscle contraction, and sodium/potassium ATPase involved in sodium ...

N2 - Creatine kinase catalyzes the reversible transfer of the gamma phosphate from ATP to creatine forming the high energy compound creatine phosphate. Muscle creatine kinase (CKm) activity maintains energetic homeostasis as variations in energy requirements dictate that ATP be readily available. Recent studies suggest that CKm activity is altered during aging. Proteomic analyses have shown that CKm is 3-nitrotyrosine (3-NT) modified and carbonylated in aged rodent skeletal muscle. However, it remains unknown if these modifications affect its structure and activity. To address this we characterized oxidatively modified CKm from the quadriceps of young, middle-aged, and aged mice. Our data ...

Agreement with respect to increased CK-MB as defined by the reference ...
CK (creatine kinase) is an enzyme (protein) found in several tissues, including muscles and the heart. Depending on the tissue, different forms of CK are present: CK-MM is primarily present in skeletal muscles, CK-MB represents 30% of CK from the heart, while CK-BB comes from the brain and smooth muscle, such as the intestinal walls. Atypical forms of CK (macro CK1 and macro CK2) can also be present. CK electrophoresis is most useful when muscular or cardiac disease does not seem to be responsible for the increased level of total CK.

Following acute myocardial infarction, CK-MB activity increases significantly and this elevation is highly specific for the laboratory diagnosis of myocardial infarction. Although total CK activity usually increases following myocardial infarction, in some patients only the CK-MB activity increases, while the total CK remains in the normal range. In this procedure CK activity is measured in the presence of an antibody to CK-M monomer. This antibody completely inhibits the activity of CK-MM and half of the activity of CK-MB, while not affecting the B subunit activity of CK-MB and CK-BB. Due to negligible concentrations of CK-BB in the circulation, the remaining activity, multiplied by a factor of 2, represents the activity of the CK-MB isoenzyme ...
The significance of elevated levels of the MB isomer of creatine kinase (CK-MB) when creatine kinase (CK) level is normal was studied in 400 patients with suspected acute myocardial infarction (AMI). In 350 patients both CK and CK-MB were elevated (group 1), in 21 only CK-MB was elevated (group 2), in 24 neither enzyme was elevated (group 3) and in 5 only CK was elevated (group 4). In 57% of patients in group 2 the CK level was doubled, with a characteristic enzyme curve, within the normal range, suggesting that an increase in CK had been missed because arbitrary definitions of normal were used. The median CK increase (60 IU/liter) in group 2 was greater than that in group 3 (23 IU/liter) (p | 0.001). Patients in group 1 with small AMIs had a relative increase in CK similar to that in group 2. However, patients in group 2 had a lower baseline CK level so that peak CK did not become abnormally high despite a 5-fold increase in some patients. In patients in group 1 with small AMIs, CK was elevated in
Creatine is a substance that is naturally produced by the human body from amino acids. The production of creatine occurs primarily in the kidneys and the liver, but 95% of it is found in the skeletal muscles. It is transported by the bloodstream to the muscles and is important in muscle activity.. Creatine kinase is an enzyme produced by various tissues that catalyzes the conversion of creatine in muscle activity. In clinical diagnostic testing, creatine kinase levels in the blood are measured as part diagnosis of a number of illnesses. These include acute renal failure (breakdown of kidney function), myocardial infarction (heart attack), muscular dystrophy, and rhabdomyolysis (severe muscle breakdown).. Types Of Creatine Kinase. There are two main recognized types of creatine kinase, type B and type M. The B and M stand respectively for "brain" and "muscle." Three isoenzymes of creatine kinase are recognized, CK-MM, CK-BB and CK-MB; these are formed from the basic B and M type of creatine ...

Studies on a 27-year-old man with a 3-year history of exercise-induced muscle pain, passage of red urine and elevated serum creatine kinase are described. Histological examination of a biopsy from quadriceps revealed non-specific myopathic changes with occasional clusters of subsarcolemmal mitochondria. The phosphorylase stain was normal. Phosphorous nuclear magnetic resonance (NMR) spectroscopy studies of gastrocnemius and flexor digitorum superficialis muscles showed no abnormalities at rest. During aerobic exercise there was an abnormally rapid decrease in phosphocreatine concentration but the pH remained within the normal range. There was a build-up of phosphomonoester (probably glucose 6-phosphate), usually indicative of a block in glycolysis. However, a primary defect in the glycolytic pathway seemed unlikely because muscle acidified normally during ischaemic exercise. Recovery from exercise was unusual in that phosphocreatine resynthesis and inorganic phosphate disappearance followed similar

Insulin resistance is a predictor of the development of noninsulin-dependent diabetes mellitus (NIDDM) in humans. It is unclear whether insulin resistance is a primary defect leading to NIDDM or the result of hyperinsulinemia and hyperglycemia. To determine if insulin resistance is the result of extrinsic factors such as hyperinsulinemia primary skeletal muscle cell cultures were established from muscle biopsies from Pima Indians with differing in vivo insulin sensitivities. These cell cultures expressed a variety of muscle-specific phenotypes including the proteins alpha-actinin and myosin, muscle-specific creatine kinase activity, and RNA encoding GLUT4, MYF5, MYOD1, and MYOGENIN. Labeled glucose was used to measure the insulin-stimulated conversion of glucose to glycogen in these cultures. The in vivo rates of insulin-stimulated glycogen production (insulin resistance) were correlated with in vitro measures of glycogen production (P = 0.007, r = 0.58). This defect in insulin action is stable ...
