Abstract:
Abstract Introduction Serum creatine phosphokinase (CPK) levels in injuries involving muscular damage, such as trauma, are used as an indicator of severity of injury. The role of CPK in frostbite injuries is unknown. We hypothesize that there is an association between serum CPK levels and the severity of frostbite injury. Methods This is a single center retrospective chart review of patients admitted to an ABA verified burn center with an ICD-10 diagnosis of frostbite from October 2022 to July 2024. Patients were excluded from the study if they were under the age of 18, had end stage renal dis

Abstract:
In vertebrate tissues, the only phosphagen is phosphocreatine (PC), and the corresponding phosphotransferase is creatine phosphokinase (CPK). Among invertebrates, a variety of phosphotransferase reactions are found in addition to CPK, including arginine phosphokinase (APK), glycocyamine phosphokinase (GPK), taurocyamine phosphokinase (TPK) and lombricine phosphokinase (LPK). Although there is some uncertainty about the exact value, the apparent equilibrium constant for the CPK reaction (K′cpk = [creatine][ATP]/[PC][ADP]), under physiological conditions similar to those of vertebrate muscle, ra

We describe a case of marked increases in serum creatine phosphokinase (CPK) associated with a dramatic exacerbation of tardive dyskinesia (TD). Chart review of eight additional patients with severe TD revealed three cases with mild CPK elevations. These cases suggest that TD, especially when accompanied by dystonia, may be associated with pathology of striated muscle.

Abstract: Although frequently in humans, hypoxic and ischemic heart diseases are poorly documented in dogs, with only few reports of acute myocardial infarction (AMI) in this species. Some electrocardiographic findings might suggest myocardium hypoxia/ischemia, like ST segment elevation or depression, but there are no studies showing whether deviations in ST segment are associated to myocardial injury and serum increase of creatine phosphokinase (CPK-MB). In order to investigate possible myocardial cells injury in poor perfusion conditions, 38 dogs were studied, 20 with normal electrocardiogra

Abstract:
Two fundamental assumptions underlie currently accepted dogma on creatine phosphokinase (CPK) function in phosphagen-containing cells: 1) CPK always operates near equilibrium and 2) CPK has access to, and reacts with, the entire pool of phosphocreatine (PCr) and creatine (Cr). We tested the latter assumption in fish fast-twitch or white muscle (WM) by introducing [14C]Cr into the WM pool in vivo. To avoid complications arising from working with muscles formed from a mixture of fast and slow fibers, it was advantageous to work with fish WM because it is uniformly fast twitch and is anatomically

The syndrome of rhabdomyolysis results from muscle necrosis and is characterized by muscle pain, elevated serum creatinine phosphokinase (CPK) concentrations, and myoglobinuria which may lead to renal dysfunction. A variety of factors can lead to rhabdomyolysis. These include crush and compression injuries, drug and alcohol ingestion, metabolic and electrolyte disturbances, hypothermia and hyperthermia, envenomation, and a variety of
