Serum neuron-specific enolase is a useful tumor marker for small cell lung cancer.

Small cell lung cancer (SCLC) may be potentially curable. A correct diagnosis of cancer cell type is important and serum markers are of great value. Although several markers have been suggested, they have been of limited value because of insufficient specificity.

Increased growth hormone responses to growth hormone releasing hormone and thyrotropin releasing hormone in patients with metastatic testicular cancer.

In 16 patients with metastatic testicular cancer and 10 age matched male control subjects growth hormone (GH) responses to growth hormone releasing hormone (GHRH; 1 microgram/kg body weight iv.) and thyrotropin releasing hormone (TRH; 200 micrograms iv.) were measured.

Clinical biochemistry of neuron specific enolase.

The soluble brain protein 14-3-2 first described by Moore and McGregor in 1965 is now known to be a cell specific isoenzyme of the glycolytic enzyme enolase (EC 4.2.1.

[Therapy of metastatic carcinoid with the somatostatin analog octreotide and with recombinant interferon alfa 2b].

A 69 year-old male with carcinoid syndrome and undetectable primary tumour, but disseminated liver metastases, was treated with somatostatin analogue octreotide (Sandostatin) and later additionally with recombinant interferon alpha 2 b (r IFN alpha 2 b, Intron A). The carcinoid symptoms (flushing, diarrhoea) were stopped within hours by octreotide. Simultaneously, the urinary 5-hydroxyindolacetic acid (5-HIAA) excretion and serum serotonin levels decreased by more than 50%.

[Cholesterol screening in a bank for the detection of a risk population].

In October 1987 voluntary screening for cholesterol war performed in a bank. After preceding information had been issued to the participants 25 ml blood were drawn on 4 days from 667 employees (48.9% males, 51.
