ALTERATIONS OF SERUM PANCREATIC ENZYMES Age and Gender-Related Alterations of Six Se- rum Pancreatic Enzymes in Healthy Subjects
نویسندگان
چکیده
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 to delineate different properties among the enzymes. Subjects were 155 males and 172 females between ages 20 and 79 years who were apparently healthy, and were stratified by age and sex. PLAz and elastase I were assayed by RIA, trypsin (ogen) by EIA and others by activity. The pancreatic enzymes, except PLAz, were significantly elevated with age, although they declined in males in the 260 age group. There were significant sex differences in total amylase and P-amylase. Total amylase was significantly higher in females than in males in the 260 age group, P-amylase in the 40-49 age group. Age should be considered in the valuation of serum enzymes except PLA2, sex difference should be considered in the valuation of amylase (total and P-amylase) .

The ontogenesis and specific activities of pancreatic (trypsin, chymotrypsin, amylase and lipase) and intestinal enzymes (alkaline phosphatase, aminopeptidase N) were investigated in Kutum (Rutilus frisii Kutum) from the onset of exogenous feeding (3 day after hatching, DAH) to the juvenile stage at 50 DAH. Trypsin- and chymotrypsin-specific activity showed similar patterns and increased with l...

Background: Lichen planus (LP) is a chronic inflammatory disease involving the skin, mucous membranes and appendages. Like other chronic inflammatory diseases, it may be associated with metabolic disorders and dyslipidemia. Due to the discrepancies in the results of previous studies and lack of a similar study on an Iranian population, we decided to investigate and compare the serum lipid...
