Clinical study of exocrine pancreatic function test by oral administration by N-benzoyl-L-tyrosyl-p-aminobenzoic acid. 1981

T Kimura, and H Wakasugi, and H Ibayashi

The clinical usefulness of a simple exocrine pancreatic function diagnostic test (PFT) was examined by the oral administration of 500 mg of N-benzoyl-L-tyrosyl-p-aminobenzoic acid. Recovery of p-aminobenzoic acid (PABA) in the urine was significantly lower in patients with calcifying chronic pancreatitis (58.6%) and noncalcifying chronic pancreatitis (68.6%) than in healthy normal subjects (81.0%; p less than 0.001 and p less than 0.05, respectively). Abnormally low values were demonstrated in 15 out of 19 (78.9%) chronic pancreatitis cases. In comparing the PFT with the pancreozymin secretin test, a good correlation (P less than 0.001) with maximum bicarbonate concentration was detected. In cases which were abnormal with respect to the PFT, the recovery rate of PABA was increased by the administration of antacids or digestive enzyme preparations (average increase of 24.1 or 29.8%, respectively). These results suggest that this test is also useful for the evaluation of therapeutic effects in patients with pancreatic diseases.

UI MeSH Term Description Entries
D010129 4-Aminobenzoic Acid An aminobenzoic acid isomer that combines with pteridine and GLUTAMIC ACID to form FOLIC ACID. The fact that 4-aminobenzoic acid absorbs light throughout the UVB range has also resulted in its use as an ingredient in SUNSCREENS.

D010195 Pancreatitis INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.

D002766 Cholecystokinin A peptide, of about 33 amino acids, secreted by the upper INTESTINAL MUCOSA and also found in the central nervous system. It causes gallbladder contraction, release of pancreatic exocrine (or digestive) enzymes, and affects other gastrointestinal functions. Cholecystokinin may be the mediator of satiety.

D002908 Chronic Disease Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).
