[Bone alkaline phosphatase as an activity parameter of acromegaly].

Serum levels of growth hormone (GH: arithmetic mean of three measurements eight hours apart), somatomedin C (SmC), alkaline phosphatase activity and the bone isoenzyme of alkaline phosphatase (as the liver/bone isoenzyme ratio) were measured in 26 patients with acromegaly (11 men and 15 women; mean age 45.5 [24-66] years), 18 in the active and eight in the nonactive phase of the disease. Activity was characterized by a raised (660 [330-1149] ng/ml), inactivity by a normal (186 [40-300] ng/ml) SmC concentration. All 18 patients with active acromegaly had an abnormally low liver/bone isoenzyme ratio (mean of 0.66 [0.01-1.28]). In seven of the eight patients with inactive acromegaly it was within normal limits. Thus measurement of bone alkaline phosphatase, which is significantly cheaper than that of SmC, is suitable for assessing activity.

[Behavior of the erythrocyte glucose-6-phosphate dehydrogenase in patients with functional thyroid disorders and in hyperthyroxinemic rats].

This paper deals with the activity of glucose-6-phosphate dehydrogenase in patients with hyper- and hypothyroidism as well as in hyperthyroxinaemic rats. The activity of glucose-6-phosphate dehydrogenase is enhanced in red blood cells of hyperthyreotic patients and hyperthyroxinaemic animals. The activity will be decreased to normal range in patients by administration of antithyreotic drugs, such as thiamazole. Patients with hypothyroidism exhibit decreased enzymatic activity. It is suggested that thyroid hormones stimulate the HMP-shunt in red blood cells as a defence mechanism against additional oxidative stress.

[The problem of cardiac metastases].

Report on metastases of the myocardium of a bronchial carcinoma in a 66-year-old woman. On the basis of an own case as well as of literature the author adopts a definite attitude to frequency, localisation and diagnostics of the secondary tumours of the myocardium.

[Sarcoidosis of the central nervous system].

Report on a 31-year-old man who fell ill from a meningoencephalitis in Boeck's disease. The course was subacute, in which case at first meningitic, later on focal encephalomeningitic symptoms stood in the first place. In the post-mortem examination a severe epitheloid-cellular granulomatosis of brain, spinal cord and their meninges was established. An affection of the lungs, of the bronchopulmonary lymphatic nodes, liver and spleen was also to be verified. It is referred to the diagnostic difficulties and the evident variability of the clinical picture of a cerebromeningeal sarcoidosis.

[Nephrotic syndrome after treatment with penicillamine in Wilson's disease].

In a 33-year-old man with Wilson's disease a nephrotic syndrome appeared as a severe complication under penicillamine therapy. Under strong observation and exact controls of protein in the urine, leucocytes, differential blood picture and thrombocytes after interruption of the medication and retrogression of the side-effects a retarding new stabilisation of penicillamine can take place. Other side-effects of penicillamine observed as well as control measures under a long-term treatment with penicillamine are briefly discussed.
