A significant decrease in alkaline phosphatase (AP) activity and mucosal thickness and increase in ulcer index (UI) was observed in aspirin treated stomach and duodenum of albino rats. However, pretreatment with C. pepo fruit pulp extract for 14 consecutive days showed increase in AP activity and mucosal thickness along with decrease in UI, suggesting gastroduodenal protective and anti-ulceroge...

Methods. Frozen sections obtained from eight human autopsy eyes were placed on gelatincoated slides. After blocking of nonspecific binding sites, the slides were incubated with rabbit polyclonal antibody to the latency-associated peptide (LAP) region of human TGF-01, TGF02, and TGF-/33 precursors, followed by the incubation with biotinylated swine anti-rabbit IgG. Subsequently, a streptavidin-l...

1. The action of beryllium on the following enzymes has been examined: alkaline phosphatase (Escherichia coli and kidney), acid phosphatase, phosphoprotein phosphatase, apyrase (potato), adenosine triphosphatase (liver nuclei, liver mitochondria, brain microsomes), glucose 6-phosphatase, polysaccharide phosphorylases a and b, phosphoglucomutase, hexokinase, phosphoglyceromutase, ribonuclease, A...

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.

Background: Gibberellic acid (GBA) is a naturally occurring and commercially produced plant growth regulator which may cause a variety of effects including the stimulation of seed germination in some cases. Histochemical changes in testicular tissue including carbohydrates, lipids and alkaline phosphatase enzyme changes were evaluated. Materials and Methods: Twenty seven mature male rats after ...

Introduction: One of the vital enzymes during spermatogenesis, which is one of the pluripotency factors of stem cells and contributes to maintaining their pluripotency is alkaline phosphatase. ZBTB16 and ZFP proteins are critical elements in stem cells which are expressed in pluripotent stem cells and maintain their pluripotency due to their role in messaging pathways. Material & Methods: The ...

Since serum alkaline phosphatase increases in fluoride therapy for osteoporosis, it is generally accepted that fluoride stimulates bone formation. However, histochemical studies have shown that alkaline phosphatase is also increased in resorbing osteocytes. Fluoride is toxic to metabolically active bone cells, alkaline phosphatase is released, and serum alkaline phosphatase increases. We propos...

1. Incubation of Schistosoma mansoni for 5 min in a phosphate-buffered medium, pH 7.4, released tegumental material containing the following phosphohydrolase activities: alkaline phosphatase, 5'-nucleotidase, glycerol-2-phosphatase, glucose 6-phosphatase, phosphodiesterase and ATPase. 2. Maximum activity of these enzymes was measured at pH 9.5; however, the phosphodiesterase and ATPase activiti...

In a previous communication (Li, H.-C., Hsiao, K.-J., and Chan, W. W. S. (1978) Eur. J. Biochem 84,215-225) we reported the purification of a divalent cation-independent, nonspecific phosphoprotein phosphatase (phosphatase S, M, = 35,000) from canine cardiac muscle to apparent homogeneity. It was found that the homogeneous enzyme preparation exhibited significant activity toward p-nitrophenyl p...

Purified chicken intestinal alkaline phosphatase is active at pH 8 to 9, but becomes rapidly inactivated with change of pH to 6 or less. Also, a solution of the inactivated enzyme at pH 4.5 rapidly regains its activity at pH 8. In the range of pH 6 to 8 a solution of purified alkaline phosphatase consists of a mixture of active and inactive enzyme in equilibrium with each other. The rate of ina...
