alpha-amylase e.c.3.2.1.1. (1,4 glucan, 4 glucanohydrolase) can be obtained from salivary glands, pancreas and microorganisms such as pseudomonas and asperigllus, as well as muscles and ovarian tubes.1.2 alpha-amylase from bacillus subtilis #1024(a tcc 465)* was purified with a highest degree of purity in our laboratory (31.59 u/mg). the extracellular alpha-amylase was subjected to different pu...

Pure amylase was isolated from pancreata and parotid glands of the baboon, an animal which has a serum amylase level and renal clearance of amylase (C(Am)) similar to man. After bolus injection, both pancreatic and salivary amylase rapidly disappeared from the serum in a monoexponential fashion with a mean serum half-time of approximately 83 min. Only about 24% of the amylase cleared from the s...

Bacterial amylase from Bacillus subtilis and fungal amylase from Aspergillus niger were potential source for industrial exploitation in the field of amylase production. Hence, this study on bacterial amylase and fungal amylase was done to compare the kinetic parameter of both the types of amylases. 30-60% ammonium sulfate precipitation has done which showed 90 % of purification of both the part...

Background and Objectives: Serum amylase increases and its excretion fraction decreases in patients with renal failure. Excretion fraction can be used as a diagnostic way in individuals with acute renal transplant rejection. In this study, the association between amylase excretion fraction and acute renal transplant rejection, was investigated in pediatrics.   Methods: in this case - control s...

We describe a simple and rapid method for measuring pancreatic and salivary type amylases using the Hitachi 705 analyser. The determination is based on the inhibition of salivary amylase using an inhibitor isolated from wheat germ. The precision of the proposed method was very good: within-day precision varied from 0.4 to 2.5% (CV) and day-to-day precision from 2.2 to 3.7% (CV). The new applica...

1. Rabbit antisera to purified rat parotid alpha-amylase were prepared. 2. The relationships between rat parotid-gland, pancreatic, serum and liver amylase were investigated by using the antisera in immunodiffusion, immunoelectrophoresis and immunoinhibition experiments. 3. Serum and liver amylase were identical, and very similar to parotid-gland amylase; pancreatic amylase was, however, quite ...

To determine the mechanism(s) responsible for glucocorticoid-induced increases in amylase content in pancreatic acinar AR42J cells, we examined the effects of dexamethasone on amylase protein biosynthesis, steady-state mRNA levels, and gene transcription. Dexamethasone treatment led to a dose-dependent increase in amylase synthesis which was one-half maximal at 2 nM and maximal at 100 nM where ...
