A new type of hereditary muscle disease, characterized by weakness and painful spasms during effort, without electrical activity in the shortened muscles, is described. These phenomena are limited principally to the upper limbs. In addition we found electromyographical signs of a generalized myotonic syndrome. The histological and histochemical investigations reveal only minimal non-specific signs of myopathy. The activities of
CPK
and
aldolase
in the blood serum are increased at times. A normal elevation of venous lactate was observed during ischemic work. The biochemical studies of muscular tissue exhibit normal activities of the analyzed enzymes, especially as regards phosphorylase. An increased concentration of calcium ions in blood serum may be related to the contraction during strenuous work; it is known that calcium ions are an important factor in the contraction-relaxation cycle of striated muscle. The age of manifestation varied from 4 to 33 years in 4 cases of the relatives observed. The disease shows no signs of aggravation as to the severity and extent of the disorders. The nature of the underlying metabolic defect is still unknown.

The serum activities of creatine kinase (
CPK
),
aldolase
(
ALD
) and alpha-hydroxybutyrate dehydrogenase (HBD) were determined in a group of Welsh Mountain ponies before and after a 30 minute period of neuroleptanalgesia induced by i.v. injection of Immobilon and terminated by i.v. injection of Revivon. There were slight but significant increases in the serum activities of
CPK
and HBD following neuroleptanalgesia, but no change in the serum activity of
ALD
. It is suggested that this form of neuroleptanalgesia may be associated, in ponies, with a degree of reversible myocardial hypoxic change, possibly as a result of coronary insufficiency.

Our purpose was to determine whether an apparently healthy patient who died under general anaesthesia had malignant hyperpyrexia by examining her relatives and to suggest protective measures for the relatives of the deceased patient against this complication during future general anaesthetics. The family members of the deceased patient were examined systematically to determine whether or not they were prone to develop malignant hyperpyrexia. Raised serum
CPK
and
aldolase
levels, EMG changes, histopathological examination of the striated muscle, diminished muscle power during an ergometric test, and subjective symptoms revealed that other members of her family had muscular dystrophy. Our results support the theory that during general anaesthesia patients with muscular dystrophy are prone to develop malignant hyperpyrexia. Although muscular dystrophy is uncommon in Finland, affected persons should be catalogued, and preventive measures against malignant hyperpyrexia taken if they ever have to have a general anaesthetic.

The frequent association of myotonia with dystrophy and the knowledge that calcium is increased in injured skeletal muscle cells suggest a possible relationship between cell calcium and myotonic alterations. This investigation has been performed to study the role of calcium in experimental myotonia induced by anthracene-9-carboxylic acid (9-AC) in rats treated with several regimens of food and exercise. Thirty-two rats were divided into 4 groups of 8 rats each, one control and 3 experimental groups. The treatments included caffeine plus exercise (group 2), and a calcium-rich diet (group 3); these procedures were designed to increase intracellular calcium; another group was treated with 9-AC as a myotonia-inducer (group 4). The treatment for all groups lasted 60 days. No significant differences in plasma sodium, potassium, chloride and calcium between control and experimental groups were observed. Whole muscle calcium in wet tissue samples did no change with any treatment. On the contrary, mitochondrial calcium showed a significantly higher concentration in group 3 and 4.
CPK
and
aldolase
activities in groups 1, 2 and 3 were similar; but in group 4 these enzyme activities were significantly higher (p less than 0.05). The electrical and mechanical responses were not altered in any rat with any experimental treatment. Our data suggest that myotonia is a predisposing factor for an altered mitochondrial calcium homeostasis in this model; in addition, the enzyme activities of
CPK
and
aldolase
were increased in the rats of group 4 implicating that myotonia is a crucial factor in the development of enzymatic abnormalities.(ABSTRACT TRUNCATED AT 250 WORDS)

A 85-year-old man was admitted with a history of right upper arm pain following trauma. Laboratory studies included an initial
CPK
level of 5,385 IU/liter. Other laboratory values were GOT, 114 IU/L; LDH, 701 IU/L; myoglobin, 1,100 ng/ml;
aldolase
, 13.8 IU/L. The patient was presumed to have have rhabdomyolysis. A 99mTc-hydroxy methylene diphosphonate (99mTc-HMDP) scan revealed an increased uptake in the right shoulder area. 99mTc-HMDP scan is a sensitive indicator of local skeletal muscle injury in rhabdomyolysis.

To investigate the biological load of aerobic dance instruction on the body, a blood biological study was performed on 13 female instructors. The values were compared with 10 female healthy controls. The results obtained were as follows. 1. A significant negative correlation was observed between the total experience of aerobic dancing (in years) and the levels of serum phospholipids. In addition, the numbers of white blood cells and the levels of serum phospholipids, lipoperoxide, uric acid and creatinine were significantly related to aerobic dance instruction time (years). 2. The levels of serum
CPK
,
aldolase
, GOT, BUN and creatinine in the aerobic dance instructors were significantly higher than those in the controls. 3. The levels of serum
CPK
, uric acid, BUN, creatinine and Ca increased significantly after an intermediate class lesson (about 60 minutes). In addition, the numbers of white blood cells also increased after the lesson, but not significantly. Moreover, Significant decreases of the mean corpuscular volume and serum Mg were observed after the lesson.

A 70-year-old man was admitted to our hospital because of fever and progressive dyspnea in December 1989. He was already diagnosed as having erythrocytosis secondary to pulmonary fibrosis 4 years previously and the values of his hematocrit (Ht) were maintained between 44.5 and 62.9% by repeated phlebotomy. Immediately after admission, severe diarrhea developed and the Ht value was 61.5%. Around 1:30 a.m. of the 3rd hospital day, he developed disturbance of consciousness. In addition, the serum levels of LDH,
CPK
,
aldolase
, and myoglobin of muscle origin increased markedly and the Ht value showed 78.5%. While the level of consciousness was gradually restored by 600 ml phlebotomy and 1,500 ml saline infusion, dysarthria and hemiplegia became evident. The Ht value early in the morning of the 3rd hospital day was reduced to 59.4%. Although cranial CT and MRI performed 74 days and 15 months, respectively, after the onset of the symptoms failed to reveal any abnormal shadow, he was clinically suspected to have cerebral infarction. These findings emphasize that abrupt increase in Ht or blood viscosity is a possible factor triggering cerebral infarction, and adequate control of Ht value is recommended for the prevention of such a condition in the aged.

Attempts at treating idiopathic cardiomyopathy have been made both clinically and experimentally using the cardiomyopathic Syrian hamster. In recent years, the angiotensin converting enzyme (ACE) inhibitor has attracted considerable attention as an agent to treat heart failure. We administered the ACE inhibitor captopril to the cardiomyopathic hamster. In this study, 15 mg/kg body weight of captopril was administered to the cardiomyopathic hamster J2N at 5 weeks of age for 10 weeks; age matched J2N hamsters were used as non-treated control animals. At the end of captopril administration, blood was collected from the ventral aorta. Serum malondialdehyde (MDA), serum
CPK
,
aldolase
and LDH were determined, and myosin isoenzyme patterns of the extirpated myocardium were compared. Additionally, ECGs were compared and the fibrotic ratio of both ventricles determined. Serum MDA,
CPK
, and
aldolase
increased significantly in the cardiomyopathic hamster, whereas these indices were significantly inhibited in the hamster treated with captopril. The pathological ECG findings and the ventricular V3 predominant myosin isoenzyme patterns of the J2N were also much improved in the captopril group. However, the improvement in these parameters by enalapril administration was less than that seen with captopril. These results suggested that the effect of captopril is not only due to decrease of the angiotensin II level, but also due to increase in tissue kinin and vasodilatory prostaglandin which play an important role in the beneficial effect of captopril.

In thalassemia major (TM) one third of patients suffers from muscle wasting, weakness and cramps. Six patients with TM were studied. All had muscle wasting and proximal weakness; serum levels of vitamin E were low (0.6-7.0 micrograms/dl) while
CPK
, LDH and
aldolase
were normal. EMG revealed low-amplitude short-duration polyphasic potentials in 3 patients and normal activity in 3 others. Nerve conduction velocities were normal in 3 patients studied. On muscle biopsies, moderate variation in fiber size with fiber atrophy and preponderance of type 1 fibers were discovered. Our findings confirm the existence of nonspecific myopathic changes in TM. Chronic vitamin E deficiency should be considered in the pathogenesis of the myopathy in TM.

A patient with Graves' disease associated with severe muscle weakness who was finally diagnosed as polymyositis by pathological examination of the muscle is reported. A 28-year-old women was incidentally found to have hyperthyroidism when she consulted a hospital for the evaluation and treatment of anemia in 1979. She was treated with methimazole for approximately a month when she stopped the medication by herself. Approximately two yr later (Nov. 4, 1981) she consulted another hospital with complaints of palpitation and muscle weakness. Diagnosis of hyperthyroidism due to Graves' disease and thyrotoxic myopathy were made, followed by the treatment with radioiodine (4 mCi of 131I). She was further treated with propylthiouracil (PTU). Four yr after the treatment, serum thyroid hormone concentration declined to the lower level than normal and serum TSH concentration increased. She was subsequently treated with synthetic I-T4. Despite the fact she became euthyroid with the treatment, muscle weakness as well as elevated concentrations of muscle enzymes were not improved. Muscle biopsy was made in July 1983, and she was diagnosed as immune polymyositis and treatment with prednisolone and cyclophosphamide in addition to PTU or I-T4, was started. With the treatment, serum LDH decreased to the normal range. However she still has muscle weakness and serum concentrations of
CPK
and
aldolase
are still in higher levels than normal range.
