Macroamylasemia is characterized by an elevated serum amylase activity. It results from the circulation of a macromolecular complex consisting of amylase molecule and a serum component, often an immunoglobulin. The present study presents marked elevation of serum amylase level in a 43-year-old male, who had been admitted to our hospital for slight abdomen ache for 4 months. After treatment foll...

OBJECTIVES One strategy for the treatment of diabetes is inhibition of pancreatic α- amylase. Plants contains different chemical constituents with potential for inhibition of α-amylase and hence maybe used as therapeutic. MATERIALS AND METHODS Urtica dioica and Juglans regia Linn were tested for α-amylase inhibition. Different concentrations of leaf aqueous extracts were incubated with enzyme...

A 60-year-old woman was diagnosed with metastatic pulmonary adenocarcinoma (c-stage IV) with an L858R point mutation in the gene encoding epidermal growth factor receptor (EGFR). Serum amylase levels were elevated (1,531 IU/L) with the salivary-type enzyme dominating. First-line chemotherapy using carboplatin plus paclitaxel reduced serum amylase levels, although second-line gefitinib eventuall...

Tetracycline and related compounds are used extensively as broad spectrum antibiotics in the treatment of bacterial infections in ruminants. Tetracycline may cause acute pancreatitis which may result in increased serum amylase activity. However, it has been shown that administration of oxytetracycline in human results in decrease serum amylase activity. In this study changes in serum amylase ac...

Gastrointestinal disease other than hepatobiliary and pancreatic disorders was associated with hourly rates of urinary amylase excretion above the limits of normal for control subjects (88 IU/hour compared with 69 IU/hour). In hepatobiliary disease, excretion rates of more than 88 but usually less than 190 IU/hour were sometimes found. Whilst rates of urinary amylase excretion were not helpful ...

The serum levels of some pancreatic enzymes have been reported to be affected by age and gender. Currently, serum total amylase, pancreatic isoamylase (P-amylase) , lipase , trypsin (ogen) , pancreatic phospholipase Az (PLA* ) , and elastase I are utilized in diagnosing pancreatic diseases. We here compared age and gender-related alterations of these six pancreatic enzymes in healthy subjects t...

This study examined the inhibitory mechanism of galanin, a 29 amino acid polypeptide on pancreatic enzyme secretion in anaesthetised rats, isolated pancreatic acini, and lobules. Urethane anaesthetised rats with pancreatic fistulas pretreated with 3-0-methyl-glucopyranose (500 mg/kg/h) were stimulated with an intravenous bolus of 2-deoxyglucose (2-DG) (75 mg/kg). Maximal amylase secretion was m...

Streptococcus bovis is an important starch-degrading ruminal bacterium that has been implicated as being important in the etiology of a number of ruminal pathologies associated with diets high in grains. Previous studies with S. bovis have shown that amylase production was influenced by the growth substrate, but the nature of this regulation was not determined. The current study was conducted t...

BACKGROUND Conventional corn dry-grind ethanol production process requires exogenous alpha and glucoamylases enzymes to breakdown starch into glucose, which is fermented to ethanol by yeast. This study evaluates the potential use of new genetically engineered corn and yeast, which can eliminate or minimize the use of these external enzymes, improve the economics and process efficiencies, and si...

BACKGROUND AND AIMS α-Amylase in grass caryopses (seeds) is usually expressed upon commencement of germination and is rarely seen in dry, mature seeds. A heat-stable α-amylase activity was unexpectedly selected for expression in dry annual ryegrass (Lolium rigidum) seeds during targeted selection for low primary dormancy. The aim of this study was to characterize this constitutive activity bioc...
