Fractionation of serum alkaline phosphatase by either biochemical or electrophoretic techniques is often insufficient to determine the source of the elevated serum enzyme. In 31 unselected patients with high serum alkaline phosphatase a simultaneous determination of serum gamma glutamyl transpeptidase and urinary hydroxyproline excretion rates was performed, in addition to urea denaturation and...

Studies on the effect of malaria on serum lipid profile, total proteins alkaline phosphatase, certain micronutrients and some organs of the body were carried out using mice as experimental animal. Serum total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, total protein, alkaline phosphatase, manganese, zinc and copper were assessed in both control and test subjects. Significant de...

RATIONALE Decreased alkaline phosphatase activity after infant cardiac surgery is associated with increased post-operative cardiovascular support requirements. In adults undergoing coronary artery bypass grafting, alkaline phosphatase infusion may reduce inflammation. Mechanisms underlying these effects have not been explored but may include decreased conversion of extracellular adenine nucleot...

To determine whether decreased alkaline phosphatase activity in the granules from neutrophils of patients with chronic myelogenous leukemia (CML) was due to an absence of enzyme or the production of defective enzyme, we compared the immunologic properties of granule alkaline phosphatase derived from patients with CML with that of normal subjects and patients with polycythemia vera (PRy). Antise...

Plasma alkaline phosphatase and inorganic phosphorus levels were determined for 52 nestling Spanish imperial eagles from two wild populations and 22 captive adults and subadults (10 adults and 12 subadults). The exact age was known for all birds. Mean alkaline phosphatase and inorganic phosphorus were higher in chicks than in the captive adults and subadults. Sex differences were not observed, ...

CYP3A4 probably has the broadest catalytic activity of any cytochrome P450. It is a crucial task to test new drug candidates in a reliable system for their ability to induce expression of this enzyme. Firstly, a total of 300 bp core distal enhancer of CYP3A4 XREM region (-7972/-7673) were amplified from human genomic DNA. The PCR product was then ligated into a human secretory alkaline phosphat...

Vascular Calcification To the Editor: In their editorial on vascular calcification, Demer and Tintut1 incorrectly state that pyrophosphate reduces calcification by inhibiting alkaline phosphatase. Actually, the opposite is true. Alkaline phosphatase promotes calcification by reducing pyrophosphate levels. Pyrophosphate is a substrate for alkaline phosphatase,2 and this enzyme regulates pyrophos...

The existence of an alkaline phosphatase-lipoprotein-X complex was demonstrated as an abnormally moving band in the agar-agarose gel alkaline phosphatase pattern of sera from 58 patients in a group of 72 patients whose sera contained lipoprotein-X. The position of the abnormally moving band in the agar-agarose gel alkaline phosphatase pattern and the percentage of alkaline phosphatase activity ...

The present studies were undertaken to determine the role, if any, of cyclic 3',5'-adenosine monophosphate (cyclic AMP) as a chemical inducer of rat liver alkaline phosphatase. Cholera enterotoxin, given intravenously to rats, led to a rapid rise in the activity of hepatic adenyl cyclase that was 7(1/2) times greater than control values in 6 h. Cyclic AMP levels were also significantly increase...
