Attempts to convert chymotrypsin to trypsin

Trypsin and chymotrypsin in duodenal aspirate and faeces in response to secretin and cholecystokinin-pancreozymin.

The secretion of trypsin and chymotrypsin into the duodenum in response to secretin and CCK-PZ has been compared with the faecal excretion of the enzymes following similar stimulation in 47 individuals undergoing clinical investigation. The faecal output of chymotrypsin correlated well, but trypsin less satisfactorily, with the secretion of the respective enzymes into the duodenum. The faecal e...

Measurement of Trypsin and Chymotrypsin Activity in Stools to Detect Chronic Pancreatic Disease.

EDITORIAL SYNOPSIS Trypsin and chymotrypsin activity per gram of stool varies inversely with the weight of the sample in control African subjects. The total daily output of both enzymes in patients with pancreatic calcification does not differ significantly from the output of control subjects. The lower mean concentration of the enzymes in chronic pancreatic disease can be accounted for by the ...

Failure of trasylol to reduce intestinal content of trypsin and chymotrypsin in man.

The daily output of trypsin and chymotrypsin was measured in the stools of four patients with an established ileostomy under controlled dietary and metabolic conditions for a control period of four days. Trasylol, given intravenously in a dose of 500,000 units over eight hours, failed to affect the output of enzymes over the next two days, or to alter the distribution of bound and soluble enzymes.

Lymphocyte Responses to Chymotrypsin- or Trypsin V-Digested β-Lactoglobulin in Patients with Cow's Milk Allergy

: Chymotrypsin- or trypsin V- (a mixture of trypsin and chymotrypsin) digested beta-lactoglobulin (BLG) peptides were prepared and were confirmed to have much less immunoglobulin (lg)G and lgE reactivity compared with intact BLG by IgG inhibition enzymelinked immunosorbent assay and IgE dot blotting. The lymphocyte responses to intact BLG and these peptides were examined using peripheral blood ...
