A case of Rocky Mountain spotted fever in a 10-year-old boy accompanied by an unusually high degree of myalgia and muscle weakness was presented. On admission to the hospital, his creatine phosphokinase, SGOT, SGPT, and aldolase values were all abnormally high. Rash did not appear until the fourth hospital day. On the same day results of a proteus OX-19 titer of blood were reported as positive (titer 1:320) and intravenous therapy with chloramphenicol was started. The child's condition gradually improved and five months later he had no detectable muscle weakness.

Adrenaline was given intramuscularly to resting horses. It increased heart rate, sweating, blood levels of lactic dehydrogenase, aldolase, creatine kinase, glucose, lactate, free fatty acids and glycerol. Responses to isoprenaline, to noradenaline and to adrenaline after pretreatment with propranolol indicated that beta receptors were involved in stimulation of tachycardia, sweating, lipolysis and muscle glycogenolysis, and alpha receptors in stimulation of liver glycogenolysis and leakage of intracellular enzymes. The time course and relative magnitude of the effects on different enzymes was not identical to that produced by exercise.

The enzymes in perilymph of the inner ear scala and within fluid filling the middle ear cavity were investigated in the fetal guinea pig near term. Perilymph lactic dehydrogenase (LDH) exhibited differential activity between fetal scalae vestibuli and tympani, and LDH, aldolase, phosphohexose isomerase and creatine phosphokinase in perilymph of particular fetal scalae were elevated in activity in activity in comparison to corresponding maternal values. Moreover, LDH displayed different isozyme patterns for antenatal and gravid perilymph. In the middle ear fluid, all of the above enzymes were encountered but varied somewhat from the quantities determined for either prenatal perilymph or maternal serum. After gravid guinea pigs were exposed to a tone of 4 kHz, 100 dB SPL for 2 hours, LDH of the fetal middle ear fluid was reduced in activity 24 hours later. The metabolic significance of the fetal distinctions in the ear fluids and the clinical implications of the current work are discussed.

A study was made of changes in outflux, extractability and enzyme (aldolase and creatine kinase) activity of muscle proteins induced by thermal action in skeletal muscles of R. temporaria L. Under a 15-minutes action of temperatures under 36 degrees C, which do not produce any contracture or fall of excitability, changes in a fraction of protein outfluxed from muscles were observed. The thermal action accompanied by the fall and irreversible loss of excitability (above 36 degrees) resulted in the fall of extractability and enzyme activity of water-soluble proteins extracted from homogenized muscles in addition to prolonged changes in the fraction of outfluxed proteins. The increased binding of aldolase by actomyosin under thermal injury of muscle is established. Changes of outflux extractability and enzyme activity of proteins during the thermal alteration of muscle are considered with regard to data about the complexing of muscle proteins.

The rate of distribution of cell enzymes between the intravascular and extravascular space was studied, following a sudden decrease of enzyme activities in plasma. This rapid decrease of enzyme activities was achieved in rats by a rapid exchange of the blood with a twofold volume of a suspension of homologous erythrocytes in isoosmolar bovine serum albumin solution. After this plasmapheresis, the activities of seven cell enzymes in the plasma were decreased to 14 to 22% of their original values. The subsequent increase in activities showed different kinetics, depending on the enzyme. After 120 min, creatine kinase had reached the starting activity; malate dehydrogenase and aldolase reached their original activities after 180 min. Aspartate aminotransferase, glutamate dehydrogenase, alanine aminotransferase and pyruvate kinase increased more slowly and they had still not reached their starting values after 240 min. Repetition of the plasmapheresis after 90 min had no obvious effect on the kinetics of the subsequent activity increase. During the first minutes after plasmapheresis the adjustment of the activity equilibrium between the interstitial and the intravascular compartments depends mainly on the capillary permeability. It is therefore possible to determine half-life constants for the distribution of enzymes within the extracellular space. The constants for malate dehydrogenase and aldolase are almost identical with those determined by intravenous injection, whereas there are discrepancies in the constants for the remaining enzymes. The constants for pyruvate kinase and glutamate dehydrogenase are significantly lower, while those for aspartate aminotransferase, alanine aminotransferase and creatine kinase are significantly higher, than those determined after intravenous injection. Possible reasons for these differences are disucssed.

Twenty-one patients developed acute renal failure in association with nontraumatic rhabdomyolysis and myoglobinuria. The illness followed an overdose of ethanol, heroin, or other depressant drug in 18 patients. Lethargy or coma was present in 17 patients and muscle swelling in 11. Evidence of rhabdomyolysis included markedly elevated creatine phosphokinase, myoglobinuria, and aldolase in blood. Initial biochemical findings were similar to those of acute renal failure due to other causes, but the abnormalities were exaggerated. There was a disproportionate rise in serum creatinine concentration in relation to serum urea nitrogen concentration. Profound hyperuricemia was present in most patients. Transient hypercalcemia developed during the diuretic phase in 5 patients. One patient died. We conclude that nontraumatic myoglobinuria with acute renal failure is not infrequent and may occur after an overdose of ethanol or heroin. The disease has good prognosis despite severe hypercatbolism and untreated profound hyperuricemia.

The activity of the following enzymes in clinically normal newborn calves was investigated: glutamate-oxalacetate transaminase (GOT), glutamate-pyruvate transaminase (GPT), alkaline phosphatase (APh), creatine phosphokinase (CPhK), lactate dehydrogenase (LDH), leucine-aminopeptidase (LAP), aldolase (A), and cholinesterase (ChE). The studies were carried out at the first hour prior to offering colostrum as well as at the 6th, 12th, 24th hr and on the 2nd, 3rd, 4th, 5th, 7th, 10th, 15th, and 20th day following it first intake. Regularly rising values of the enzyme activity up to the 24th hour were observed with APh, GOT, GPT, CPhK, and LAP. The aldolase enzyme (after colostrum had been given for the first time) in all animals showed a statistically significant drop of activity at the 6th hour. The activity of LDH displayed a consistently rising trend up to the end of the experimental period. The cholinesterase activity showed high values immediately following birth, reaching those found in the dams by the end of the observation period.

In eight women with polymyositis (three patients), systemic lupus erythematosus (SLE) (three patients), rheumatoid arthritis (one patient) and shoulder-hand syndrome (one patient), weakness developed during high dose prednisone therapy. These women were studied using serial functional and manual muscle tests, determination of serum glutamic oxaloacetic transminase (SGOT), creatine phosphokinase (CPK) and serum aldolase levels, and urinary excretion of creatine. Insidious onset of weakness was characteristic. Myalgias were seen in five patients and unusual sudden weakness in two. Weakness was always most severe in the pelvic girdle muscles; there was a lesser involvement of shoulder girdle and distal muscles. Serum muscle enzyme levels were normal in all cases, but urinary creatine excretion was invariably increased and proved to be the most sensitive laboratory indicator for clinical diagnosis and for monitoring patient improvement. Serial urinary creatine excretion and serum enzyme studies were of value in differenting steroid myopathy from a flare of myositis in patients with connective tissue disease. Diagnosis and effective management were achieved by the use of readily available laboratory and clinical procedures without resorting to muscle biopsy.

In human striated muscle obtained in surgery, an age-dependent decrease in aldolase and creatine kinase specific activities and an increase in DNA content per wet weight was found. In the group of the elderly (64-84 years), the enzymes decreased by 40-60% when compared with a group between 24 and 47 years old, while DNA content rose by a factor of 1.53 indicating loss of tissue water. Titration of aldolase and creatine kinase molecules by specific antibodies against aldolase A and creatine kinase MM isozymes, respectively, revealed very little accumulation of aldolase cross-reacting materials in the old age group (1.13 fold), and no accumulation of inactive creatine kinase molecules. Similar conclusions can be drawn from thermostability analyses of these two enzymes. The data do not support the view that accumulation of modified proteins due to random errors or to post-translational alternations is a general or causative phenomenon of aging in human muscle tissue.

Soluble enzymes were immobilized and visualized by polyacrylamide gel slabs, impregnated with the incubation medium including auxiliary enzymes. The method has several advantages over existing techniques which make use of gel films or a semipermeable membrane. The diffusion of tissue compounds is effectively limited, while auxiliary enzymes may be operative. Moreover the viscosity of the medium is temperature-independent so that the incubation temperature can be varied. To demonstrate the suitability of the method glycerol-3-phosphate dehydrogenase, lactate dehydrogenase, glucose-6-phosphate dehydrogenase, hexokinase, phosphoglucomutase and aldolase were visulaized in human or rat skeletal muscle. Cytosolic and mitochondrial glycerol-3-phosphate dehydrogenase were both visualized in the absence of added NAD+ and menadione. For the visualization of ATP producint enzymes, like creatine kinase and pyruvate kinase, the method is not suitable.
