Serum amylase activity in liver disease.
Serum amylase activity was measured in 15 normal persons and in 60 liverdisease patients. Impairment of liver was assessed by serum bilirubin and thymol turbidity values. Most of the patients had serum amylase values that were well below the normal limits. Amylase activities were related to the degree of liver dysfunction, and serum amylase decreased as the bilirubin and turbidity values increa...
متن کاملFactitiously low amylase values.
When a commercial substrate was used in the determination of serum amylase activities of patients with acute pancreatitis, results much higher than those reported by the manufacturer with similar patients were found. A failure to quantitate all of the reducing groups liberated during incubation may account for the lower results. A modified saccharogenic method has been developed, which, by incr...
متن کاملAmylase activity in cerical mucus and serum during estrus in normal and repeat breeder cattle
Aim: To compare the amylase activity in the cervical mucus and serum during estrus in normal and repeat breeder cattle and find out importance in fertility. Materials and methods: Twenty cyclic crossbred cattle were divided into two groups: normal (n =10) and repeat breeder (n =10). Animals exhibiting spontaneous estrus, were artificially inseminated (AI) twice, as per AM-PM schedule along with...
متن کاملNew chromogenic substrate for determination of serum amylase activity.
A rapid assay for serum amylase activity has been developed based on the use of a new chromogenic substrate-Cibachron Blue-amylose. The procedure requires 0.1 ml of serum and measures the production of soluble chro. mogen, the formation of which islinearwith enzyme activity. Normal human serum has a mean amylase activity of 118 ± 37 (SD) mg dye/100 ml/15 mm or, in international units, 78 ± 24 (...
متن کاملKinetic nephelometric procedure for measurement of amylase activity in serum.
We developed a kinetic procedure for determination of amylase activity in serum by use of nephelometric measurements. Light scattering from the substrate, a stable suspension of starch, is decreased as amylase hydrolyzes the starch to soluble fragments. Values obtained for serum amylase correlate closely with those determined by a method in which a starch-dye complex is used. Precision of the n...
