The metabolism of biogenic amines in experimental animals and in human subjects during acute and chronic administration of ethanol.

Ethanol has been shown to induce a shift in catecholamine metabolism peripherally from normally oxidative pathways to reductive pathways. The mechanisms of this effect may result from competitive inhibition of aldehyde dehydrogenase by acetaldehyde. The shift in metabolism cannot be found in brain and alterations in catecholamine function may reflect changes in the turnover of these amines.

Abducens nerve palsy as initial symptom of trigeminal schwannoma.

The insidious onset and slow progression of symptoms may cause delay in the recognition of trigeminal schwannomas. Two cases with abducens nerve palsy as an initial symptom are reported, in both of whom the tumour was growing mainly below and anterior to the intracavernous portion of the internal carotid artery. Early detection of clinical symptoms and thorough radiological investigations are important in the early diagnosis of these lesions.

Activities of catalase in leucocytes and glucose-6-phosphate dehydrogenase in erythrocytes of hypocatalasemia and acatalasemia.

Catalase activity in leucocytes was found to be half the normal value in hypocatalasemia and extremely low in acatalasemia. Glucose-6-phosphate dehydrogenase activity in erythrocytes was not significantly different between normal, hypocatalasemia and acatalasemia in three families of acatalasemia, but in one family lower activities than normal were found in hypocatalasemia and actalasemia erythrocytes. Other enzyme activities in blood, such as alkaline phosphatase, lactate dehydrogenase, glutamic oxaloacetic and glutamic pyruvic transaminases were not significantly different between normal subjects, hypocatalasemia and acatalasemia.

Activities of superoxide dismutase and glutathione peroxidase in the red cells of Japanese acatalasemia blood.

The activities of superoxide dismutase and glutathione peroxidase in the red cells of normal and acatalasemia bloods were compared. Superoxide dismutase activity in the red cells of Japanese acatalasemia blood was higher than in normal control, while glutathione peroxidase activity remained within normal limits. Cyanide sensitivity of superoxide dismutase in the red cells of acatalasemia blood was similar to that in normal control.
