Macromolecular alkaline phosphatase (EC 3.1.3.1) was found in the serum of a patient suffering from myasthenia gravis (adult type II) complicated with thymoma, and was shown by immunoelectrophoresis to be bound to immunoglobulins A and G (IgG). Placental alkaline phosphatase, complexed with either the patient's serum or IgG purified from the patient's serum, remained at the origin on electropho...

human brucellosis is a major health problem in developing countries. a number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. since the pathophysiology of this change is not well understood, we studied the t-cell subsets during the acute, subacute and chronic forms of human brucellosis. in this study we found alterations in t...

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 ...

We report a case of renal cell carcinoma in which up to 32% of the abnormally increased alkaline phosphatase activity in serum was contributed by a variant alkaline phosphatase originating in the primary tumor and its secondary deposits. The variant enzyme was probably an altered form of normal renal alkaline phosphatase. The rest of the alkaline phosphatase activity in the serum was of hepatic...

The neutrophilic alkaline phosphatase activity of 40 newborns was determined and found to be frequently raised, similarly to a leukaemoid reaction. The newborn neutrophil has strong alkaline phosphatase activity and is unlike the myeloid leukaemia cell which has no alkaline phosphatase activity.

Reference ranges for amniotic fluid alkaline phosphatase, gamma-glutamyltransferase, and 5-nucleotidase are described from 13 to 40 weeks' gestation. Gamma-glutamyltransferase and 5-nucleotidase activities peak early in the second trimester and then decrease to low values. Alkaline phosphatase shows a similar pattern of activity from 13 to 29 weeks' gestation, but thereafter activity increases ...

We constructed a derivative of transposon Tn5 that permits the generation of hybrid proteins composed of alkaline phosphatase (EC 3.1.3.1) lacking its signal peptide fused to amino-terminal sequences of other proteins. Such a hybrid gives alkaline phosphatase activity if the protein fused to alkaline phosphatase contributes sequences that promote export and thus compensate for the missing alkal...

uridine (lUdR) there was an increase in alkaline phosphatase activity after about 24 hr, reaching a maximum usually at about 72 hi. At this concentration, during this time, there was a relatively small inhibition of cell replication. The increment in alkaline phosphatase activity was in large measure prevented by concomitant addition of 10 /¿Mthymidine. Further, lUdR did not increase alkaline ...

This study was aimed to determine the alkaline phosphatase activity following time course (days) in the intestine of broilers. We used a sample of 54 subjects of broilers from hatching period to 56th day of age. Our finding showed a significant increase in the alkaline phosphatase activity at various levels in the different intestinal segments during the first two weeks of life and then decreas...
