A case of type 1 muscle fibre hypotrophy and internal nuclei.

A 14 year old boy was diagnosed as suffering from type 1 muscle fibre hypotrophy with internal nuclei. On histological examination of a biopsied muscle, there was selective hypotrophy of type 1 muscle fibre with internal nuclei, and focal degenerative changes were seen in a few type 1 fibres. The small type 1 fibres were arranged in small or large groups in one bundle. An EMG study of moderately weak muscles revealed low amplitude and short duration motor unit potentials as well as normal potentials and no spontaneous discharges. The H reflexes were abnormally low in amplitude comapred with the M response. The histological and electrophysiological findings suggested that the type 1 fibre involvement in the present case may have a neurogenic basis. It is likely that the clinical features of the reported cases are too variable for a single clinical entity.

Ultrastructural changes of the hypothalamo-hypophysial neurosecretory system in the magnesium deficient rats.

A magnesium deficient diet caused transient but marked degenerative changes in the rat hypothalamo-hypophysial neurosecretory system which strongly resembled in many ultrastructural respects those induced by a prolonged administration of aldosterone as previously reported by us. The possible mechanism for this selective alteration in the neurosecretory neurons has been briefly discussed with regard to aldosterone secretion.

Oculopharyngeal involvement in familial neurogenic muscular atrophy.

A Japanese family with progressive spinal muscular atrophy is presented. Seven members in two generations were affected and the mode of inheritance was probably an autosomal recessive trait. A characteristic feature of this family was the presence of oculopharyngeal involvement in some of the affected members, in addition to the variable distribution of muscular atrophy among each of the affected members, such as mainly proximal or distal atrophies in the limbs. In one case the oculopharyngeal weakness appeared without limb involvement. The changes in the extremities were thought to be of neurogenic origin, and so was the progressive external ophthalmoplegia seen characteristically in these cases, although the latter was similar to ocular myopathy.

Elevated pancreatic glucagon in moderately obese patients: relationship of fatty liver and hypertriglyceridemia.

To elucidate if the presence of fatty liver and hypertriglyceridemia (HTG) influences pancreatic A-cell function in obesity, basal and arginine-stimulated glucagon (IRG) secretions were studied in 7 normal subjects and in 28 moderately obese patients (OB) with normal glucose tolerance. The patients were divided into 4 groups, based on the presence of fatty liver and/or HTG. BMI was similar in all four obese groups. Basal IRG, as well as the sum of secretory response to arginine, namely sigma IRG values, were significantly (p less than 0.01) higher in the OB subgroup having both fatty liver and HTG than in the other three groups; these values were similar in subgroups of OB without fatty liver, and showed no significant difference from the normals. Basal and sigma IRG values in all OB correlated well with the degree of fatty liver and HTG, demonstrating that by stepwise analysis the effects of fatty liver and HTG were independent for basal and sigma IRG values. These results suggest that the combination of fatty liver and HTG may serve as a good predictor of hyperglucagonemia in simple obesity, and, hence, metabolic heterogeneity among obese patients should be considered in evaluating A-cell function.
