...Steven A. Atlas; Thomas E. Hesson; Jean E. Sealey; John H. Laragh 1. Purified inactive renin from human kidney or plasma was activated to a similar extent by incubation with trypsin or by dialysis to pH 3.3. 2. Trypsin- or acid-activated inactive renin was like active renal renin in terms of pH...

... basal levels. A further increase in bilirubin secretion was not observed in a subsequent perfusion with essential amino acids alone in these studies. 3. No inhibitory effect on basal or caerulein/secretin-stimulated trypsin secretion was observed during the bile salt perfusion; basal trypsin secretion...

Plasma samples from 31 normal subjects were treated (at 4°C, pH 7.0, for 2 min) with different concentrations of trypsin (500, 1000, 2000, 3000 and 4000 μg/ml) in order...

... be allocated unambiguously into one of seven categories according to the binding of trypsin to inhibitor in two kinetically apparent binding modes (β- and α-modes). 3. The distribution of α 2 -macroglobulin β:α ratios in a healthy adult population is defined, and shown to be independent of sex and age. 4...
