We report a case of primary bronchogenic adenocarcinoma, complicated by pleural effusion, in which very high pleural amylase activity was found, whilst serum amylase was normal. Isoamylase determination showed a salivary-type amylase. Concerning the origin of this enzyme, ultrastructural study of the malignant cells obtained from the pleural fluid suggested a local amylase synthesis. The pathop...

Brachybacterium sp. strain LB25 produces a maltooligosaccharide-forming amylase that improves product selectivity in water-miscible organic solvents. The enzyme hydrolyzed starch to produce maltotriose primarily. The structural gene encoding the amylase from strain LB25 was cloned and sequenced. The amino acid sequence of the product showed significant similarity (45 to 49%) to amylases from th...

The Rapignost-Amylase urinary test strip (Behringwerke Laboratories) provides an estimation of urine amylase which takes a few minutes and is easy to perform. During a period of 9 months, 84 patients had their urine tested with this strip by casualty officers in the Accident and Emergency Department of St George's Hospital, London. In addition, urine amylase, and plasma amylase and creatinine w...

Addition of albumin, gamma-globulin, alpha-casein or submaxillary mucin to the assay system for chromogenic measurement of human or rat amylase with blue starch increased the amylase activity, albumin having the most effect. These proteins seemed to increase the activity by protecting amylase from inactivation. Amylase activity was higher in urine samples showing proteinuria than in urine sampl...
