... was determined using radioimmunoassay. ET-1-like immunoreactivity in the brain regions of 1-week-old WKY and SHR rats was lower compared to older (6 and 8 weeks) rats. ET-1 levels in the central nervous system gradually increased with age in both SHR and WKY rats. However, the concentration of ET-1 in 8-week-old...

... of endogenous ET-1 was determined in the brain regions (hypothalamus, corpus striatum, pituitary, hippocampus and spinal cord), heart, adrenals, kidneys and thoracic aorta using a radioimmunoassay procedure. Blood pressure and heart rate were significantly increased in hyperthyroid rats, while they were...

... different doses of the hormone at intervals of 2 days. The plasma rpGH concentration was determined by radioimmunoassay with a lowest detection limit of 50 pg/ml. Plasma levels of rpGH were fitted to a three-compartment open model; a triexponential decrease in plasma rpGH with a rather long mean terminal...
