Plasma levels of thyrotropin-releasing-hormone in various splanchnic, renal, suprarenal, and cerebral veins.

Endogenous TRH levels were determined in plasma obtained selectively via percutaneous transhepatic and femoral catheterization. TRH was measured using a very sensitive RIA method. In the pancreatic veins, internal jugular vein, left testicular vein, and other described veins, normal peripheral levels were found.

[The hypothalamo-hypophyseal thyroid axis, plasma protein concentrations and the hypophyseo-gonadal axis in low T3 syndrome following acute myocardial infarct].

In patients with severely acute diseases, a special relationship of thyroidal hormones with decreased T3 and increased rT3 levels is known, the so-called low T3 syndrome. The aim of this study was to elucidate the involvement of the hypothalamo-pituitary thyroid axis, the pituitary-gonadal axis, the altered hepatic function, the plasma proteins in the low T3 syndrome, and the evaluation of these parameters for prognosis in patients with acute myocardial infarction. Thirty-one patients (29 male, 2 female) with AMI entered the study for the determination of hypothalamo-pituitary thyroid axis and the plasma proteins.

Effect of hypometabolism on cell injury.

Rats were given galactosamine 1 g/kg i.p. Pretreatment with propylthiouracil 14 days prior to intoxication and surgical thyroidectomy 10 days prior to intoxication significantly reduced the elevation of SGOT and GLDH activities and protected against hepatocellular necrosis 28 h after intoxication.

The use of human fetal pancreas for transplantation: experimental and clinical results.

Human fetal pancreata (15-22 weeks of gestation) were precultivated in vitro for 7 to 25 days and transplanted subcutaneously to thymusaplastic nude mice and an insulin-dependent diabetic patient. In mice, precultivated xenotransplanted pancreata showed typical transplant growth in the recipients. Histology revealed typical islets formation.

Beneficial effect of somatostatin in phalloidin-intoxicated rats. Influence on survival rate, biochemical and morphological data, and 3H-demethylphalloin absorption rate by the liver.

The effect of somatostatin in phalloidin-intoxicated rats was studied. Animals were given phalloidin i.p.
