The physical condition of 44 calves delivered by caesarean section before term was monitored by clinical and repeated laboratory examinations (analysis of AST, GLDH, gamma-GT, CPK, total bilirubin) during the first seven days of life. The newborns were divided into two groups based on the clinical observations during the first hour of life, the blood pH and the base deficit: Group 1: 30 calves without respiratory distress syndrome (vital, non asphyxial); they did not develop any diseases in the course of the experiment. Group 2: 14 calves with respiratory distress syndrome (asphyxial; 9 of these animals died in the course of the experiment. No significant differences between the vital and asphyxial calves were found in respect to the enzymes AST, GLDH, gamma-GT, CK as well as total bilirubin values measured during the first week of life. These blood parameters were within the normal range for calves delivered at term. The results do not indicate any disorder in liver and muscle functions in prematurely born calves with or without respiratory distress syndrome.

The present work summarises the experience gained with the use of extracorporeal hemoperfusion in 45 patients suffering from rheumatic diseases. During hemoperfusion, there was a decrease in the initially activated LDH, CPK, AST, ALT and AP. The reduction of the content of phospholipids and cholesterol in plasma and red blood cells is assessed as an adverse effect of hemoperfusion, since the content of phospholipids and cholesterol was under normal before hemoperfusion. The changes indicated point to the necessity of administering antioxidants and exogenous phospholipids.

The activities of the enzymes SD, GD, AAT, 5'NT, GGT, LDH and CPK were determined weekly in sera of two calves each infected with 10,000 S. bovis cercariae and in two controls. In infected animals, LDH activity increased from the first week of exposure and remained high throughout the experiment (22 weeks). GGT activity increased nine weeks after exposure and remained high. CPK activity was elevated during weeks 8-15 of infection. No change was detected in the activity of the other enzymes, nor in any enzymes of the controls.

Clinical and biochemical responses were studied after taking the measures to prevent nutrition muscular dystrophy in young cattle in the given ecological conditions. Analyzing the biological material (blood, hair, feed, soil), we found the sufficiently high saturation of heifer organisms with the microelement selenium and on the contrary, vitamin E deficiency. Sensitive indicators of the break-down of muscular tissue were the enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT), and mainly creatinine kinase (CPK): the activities of these enzymes increased significantly after the heifers had been driven to pasture. The stay of animals in the run to get them used to the physical load before going to the pasture was not found to be a sufficient measure to prevent muscular nutrition myodystrophy if the animals had not been administered vitamin E and selenium supplements. Of the one hundred heifers we examined, seven animals began to show the signs of nutrition muscular dystrophy; none of these animals had been administered vitamin E and selenium supplements.

In the cerebrospinal fluid and serum the activity was determined of phosphocreatine kinase (CPK), lactic dehydrogenase (LDH), aspartate transaminase (AspAT) and alanine transaminase (AlAT) in 107 cases of multiple sclerosis. The results were compared with those in a control group of neurosis and a highly significant (three times) increase was observed in the activity of CPK and LDH in the cerebrospinal fluid as a result of organic damage to the brain tissue. By chromatographic method direct data were obtained indicating that increased CPK activity in the cerebrospinal fluid was connected with the CK-BB isoenzyme, that is with the cerebral fraction of the enzyme.

Plasma CPK activity and the activity of isoenzymes MDH, AST and LDH were assessed in 60 patients with myocardial infarction of different severity, with reference to the time since the onset of the attack. The peaks of CPK and MDH-C activity were reached sooner than those of LDH-M and AST-C, while the CPK and MDH-C curves were similar. The severity of the disease showed correlation to later onset of enzyme peaks and markedly delayed decrease in the respective values. Increased activity of mitochondrial isoenzymes and blood LDH-M provided additional information on the severity of the disease. Delayed normalization of these activities was associated with a poor diagnosis.

A 32-year-old male (Mr. A.), monitored during an 8-d heat acclimation (HA) investigation, unexpectedly exhibited heat intolerance and heat exhaustion. Thirteen other males completed HA without indications of either heat intolerance or heat exhaustion. Because Mr. A. responded normally to HA on days 1-4, the intervention of an unknown host factor on days 5-8 was suggested. Mr. A.'s heat exhaustion episode (day 8) was apparently forewarned by loss of body weight and increased delta HR, delta Tsk (days 5-8) and delta Tre (days 7-8) during daily 90-min trials. His symptoms indicated classical salt depletion heat exhaustion, but the calculated salt deficit (less than 0.1 g NaCl.kg-1 body weight) was mild. Post-heat exhaustion serum enzyme levels were either normal (ALT, AST) or acutely elevated (CPK). Blood beta-endorphin and cortisol levels were six times and two times greater than control values, respectively. This case report is unique because clinical/physiological measurements and blood analyses were performed before, during, and after heat intolerance and heat exhaustion.

Fifty-four patients with acute myocardial infarction were evaluated repeatedly, with 28 of those treated with piracetam, and 26 used as controls. Piracetam produced a considerable favorable effect on the clinical course of myocardial infarction, as reflected in a more rapid clinical improvement of acute circulatory insufficiency and an analgetic effect. The drug reduced heart rate and moderately elevated systolic arterial blood pressure. Positive changes in total CPK, LDH, AST and ALT activities, and in ECG from 12 and 35 leads were quicker to come.

The study of patterns of serum AST, ALT, CPK, LDH, and glycogen phosphorylase (GP) activity following bicycle ergometry in 26 male patients 1 to 1.5 months after myocardial infarction demonstrated no increase in AST, ALT and CPK activity, whereas total LDH activity was increased, with a tendency to elevated LDH-1 and LDH-2 fractions, as compared to the baseline, in those cases where exercise was discontinued because of ST depression. Patients with favorable response to bicycle ergometry that continued until the submaximum heart rate for a given age was achieved showed a tendency to elevated LDH-5 that may be a physiological response to exercise. The demonstrated increase in total GP activity, both in patients with exercise-induced ST depression and in those with elevated ST from the leads corresponding to the site of myocardial infarction, may reflect stress-induced reversible ischemia.

An examination of 400 coronary patients demonstrated a relationship between increased serum CPK, AST, LDH and LDH-1, and the spread and severity of myocardial infarction (MI). In transmural and large-focal MI, CPK activity peak observed on Day 1-2 of the disease was increased 4-12-fold, and that of AST, 5-fold, as compared to the upper limit of the normal range. In small-focal and subendocardial MIs, the increase was 1.5-8-fold and 3-fold, respectively. In angina pectoris, serum CPK activity also showed an increase, although a less manifest one. A CPK activity level of 175 IU is proposed as a discriminative level to be used in the diagnosis of large-focal myocardial infarctions.
