introduction: hydatid cyst disease is caused by the protoscolices of echinococcus granulosus. alkaline phosphatase (alp) enzyme is required for metabolism, physiology, immunology, and nutrients absorption in parasite. the aim of this study was to compare the level of alp activity (as a pathological biomarker) in hydatid cyst protoscolices (hcp) with that of sheep liver tissue and to determine t...

Treatment of immature mice with both follicle-stimulating hormone and human chorionic gonadotrophin in vivo resulted in large increases in the specific activities of ovarian alkaline phosphatase and alkaline nucleotidase. The specific activities of other ovarian enzymes studied were not altered by gonadotrophin treatment. A simultaneous change in the Michaelis constant of ovarian alkaline phosp...

introduction : deproteinized bovine bone mineral (bio-oss) is a xenogenic bone substitute, widely used in maxillofacial bone regeneration. the aim of this in vitro study was to investigate its influence on the growth behavior of human osteosarcoma cell line, saos-2 culture, and compare it with the physiologic dose of dexamethasone, an inductive factor for osteoblasts. materials and methods: hum...

Bile duct ligation in the rat leads to a rapid increase in hepatic and serum alkaline phosphatase activity. Within 12 hr after bile duct ligation, hepatic alkaline phosphatase has increased 7-fold and serum alkaline phosphatase activity 2(1/2)-fold. The elevation in the serum activity is completely due to an increase in an isozyme that appears to originate in the liver. This serum isozyme and l...

The influence of non-steroidal anti-inflammatory drugs (NSAIDs) and of disease activity on the serum alkaline phosphatase concentration was examined in patients with rheumatoid arthritis, osteoarthritis, and polymyalgia rheumatica. Concentrations of serum alkaline phosphatase were similar both in patients with rheumatoid arthritis taking NSAIDs and in those not taking NSAIDs. In patients with o...

In the Baltic Sea, peptidase and alkaline phosphatase activities always show the same pattern in nutrient gradients: increasing enzyme activities with decreasing dissolved inorganic nitrogen (DIN) and phosphate. The field experiments reported here suggest that peptidase activity may be regulated by DIN in a manner similar to that of alkaline phosphatase by phosphate. In nutrient gradients estab...

water and soil salinity are two of the most important limiting factors in crop production. phosphatase enzymes are widely found in plants. phosphatase enzymes are responsible for de-phosphorylation of organic phosphate and altering it to mineral phosphate. germination experiments were conducted using two bread wheat cultivars, namely, iniya66 and ghods along with application of different nacl p...

Desensitization of adenylate cyclase-coupled beta-adrenergic receptors in avian erythrocytes results in a 40-65% decrease in agonist-stimulated adenylate cyclase activity and correlates with increased phosphorylation of beta-adrenergic receptors. To assess the role of phosphorylation in desensitization, membranes from isoprenaline- and dibutyryl cyclic AMP-desensitized turkey erythrocytes were ...

Approximately 10% of the alkaline phosphatase activity in human kidney is derived from the intestinal-type alkaline phosphatase isoform, which can be differentiated from adult intestinal alkaline phosphatase by selective reactivity with monoclonal antibodies. The NH2-terminal sequence of the renal intestinal-type alkaline phosphatase was shown to be identical to sequences of the adult and mecon...

Background: In the present investigation radiation and cadmium induced biochemical changes in the kidney of Swiss albino mice have been studied. Materials and Methods: For this purpose, adult male Swiss albino mice (6-8 weeks old) were divided into four groups. Group I (sham-irradiated), Group II (treated with CdCl2 solution 20 ppm), Group III (irradiated with 1.25, 2.5 and 5.0 Gy gamma rays), ...
