We describe a case of exudative pleural effusion in a patient with mucinous pulmonary adenocarcinoma. Pleural fluid examination showed markedly raised amylase with normal serum amylase concentration. There was no clinical or radiological evidence of oesophageal rupture or pancreatitis. The case illustrates the importance of considering pulmonary malignancy in the context of amylase-rich pleural...

Background: Enzyme engineering by immobilization techniques has proven to be well compatible with the other chemical or biological approaches aiming to improve enzyme’s functions and stability. Zeolites are porous alumino-silicates with a wide range of porosity and particle size along with the other remarkable properties such as high surface area, high stability against a wide range temperature...

We assayed serum and urine specimens for amylase activity by the nephelometric (I),dyed-starch (Amylochrome) (II), and mayloclastic (III) techniques. For serum, the correlation coefficients of the regression lines were: I vs. II, 0.978 (n = 106); I vs. III, 0.736 (n = 110); and II vs. III, 0.739 (n = 108). For urine, they were I vs. II, 0.938 (n = 49); and I vs. III, 0.752 (n = 46). Because cal...

Muffin et al. (1), in this issue, describe a more specific method for pancreatic ainylase in serum. Amylase of salivary origin is precipitated with a monoclonal antibody, and the amylase remaining is presumed to come from the pancreas. It is likely that their test will be more specific for pancreatic disease. Since the recognition of multiple sources of antylase and of the frequency of hyperamy...

Background and aims Serum amylase is a traditional measure used to establish the diagnosis of acute pancreatitis (AP). The current study aimed to assess the predictors and clinical outcome of AP with low serum amylase. Methods All patients were divided into two groups, based on their serum amylase level within the first 2 days after hospital admission: group 1 (amylase ≥300 U/L) and group 2 (...

the experiment was conducted to determine α-amylase activity and the effect of seven plant species extracts including punica granatum l. (punicaceae), rheum officinale b. (polygonaceae), rhus coriaria l. (anacardiaceae), artemisia sieberi b. ( compositae), peganum harmala l. (nitrariaceae) , datura stramonium l. (solanaceae) and thymus vulgaris l. (lamiaceae) on α-amylase activity of four store...

To evaluate a new method for measuring pancreatic amylase in serum, in which the salivary isoenzyme is inhibited with a specific monoclonal antibody, we determined the activity of pancreatic and salivary amylase in sera from 103 healthy subjects and from 114 hospitalized patients having a wide range of total amylase activities. CVs for the proposed method ranged from 0.8% to 5.1% (within day) a...

The side effects associated with the usage of synthetic antidiabetic drugs make it imperative to search for alternative drugs from medicinal plants. Therefore, this study was aimed at evaluating the α-amylase and α-glucosidase inhibitory potential of Calotropis procera leaf, as well as its possible mode of inhibiting these enzymes. Acetone, aqueous and ethanolic extracts of C. procera leaf was ...
