Although low-power laser irradiation provides many anabolic effects such as acceleration of bone formation, the effects of different pulse frequencies used during laser irradiation on bone formation have not been elucidated. Osteoblastic cells isolated from fetal rat calvariae were irradiated once with a low-power Ga-Al-As laser (830 nm, 500 mW) in two different irradiation modes; continuous ir...

introduction: the aim of this study was to evaluate the correlation between serum levels of ovarian and gonadotropin hormones, age and number of follicles with follicular alkaline and acid phosphatase activity in infertile women under controlled ovarian hyperstimulation. methods: after collection of follicular fluid and calculation of the number of follicles, the specific activity of alkaline (...

To determine whether alkaline phosphatase (ALP) can cause the mineralization of collagenous matrices in vivo, bovine intestinal ALP was covalently bound to slices of guanidine-extracted demineralized bovine dentin (DDS). The preparations were implanted subcutaneously over the right half of the rat skull. Control slices not treated with the enzyme were implanted over the left half of the skull o...

Alkaline phosphatase (ALP, 3.1.3.1) is a dimeric glycoprotein present in humans that catalyses the hydrolysis of orthophosphoric monoesters at alkaline PI! (1). It has been reported to occur in abundance in human bile canaliculi, bone, intestine, placenta and kidney (1). Hence serum ALP levels has been extensively used as a diagnostic tool for hepatobilliary disorders particularly in patients w...

OBJECTIVES To examine the expressions of IL-17, IL-22, and IL-23 receptors in four osteoblast models and the effects of IL-17, IL-22, and IL-23 on osteoblasts. METHODS Gene expression levels of receptors, alkaline phosphatase (ALP), osteocalcin (OCN), and Runt-related transcription factor 2 (Runx-2), were evaluated by RT-PCR and real-time RT-PCR. Proliferative responses and cell cycle analysi...

BACKGROUND Spirocerca lupi is a nematode of Canidae that matures within the esophageal wall to form fibroblastic nodules with potential for malignant transformation. Diagnosis is based on histopathologic examination, but false-negative results may be obtained from samples collected by endoscopy. Serum alkaline phosphatase (ALP) activity, frequently increased in hepatobiliary disease, is also in...

In this study, an effective and portable method for enzyme activity detection inhibitory evaluation was developed based on the alkaline phosphatase (ALP)-mediated reaction in a personal glucose meter (PGM). method, ALP catalyzes hydrolysis of substrate amifostine (WR-2721) to produce ethanethiol (WR-1065), which can trigger reduction ferricyanide (K3[Fe(CN)6]), electron transfer mediator test s...

Alkaline phosphatase (ALP) is present in human preadipocytes. The aim of this study was to determine the relationship between anthropometry and serum levels of ALP isoenzymes, liver enzymes, albumin, and bilirubin. Anthropometric variables; serum total, bone, liver, and intestinal ALP levels; and alanine aminotransferase (ALT), albumin, total protein, total bilirubin, and g-glutamyltransferase ...

This study investigated the effects of Korean Red Ginseng (KRG) on radiation-induced bone loss in C3H/HeN mice. C3H/HeN mice were divided into sham and irradiation (3 Gy, gamma-ray) groups. The irradiated mice were treated for 12 wk with vehicle, KRG (per os, p.o.) or KRG (intraperitoneal). Serum alkaline phosphatase (ALP), tartrate-resistant acid phosphatase, estradiol level, and biomechanical...

Experiments involving 120 male Wistar rats were performed to study the effect of treatment with cadmium acetate and external irradiation. A single 0.5 mg/kg body weight dose of cadmium acetate was administered intratracheally. Shortly thereafter, the animals received a single whole-body exposure to 4 Gy gamma rays (cesium source). Findings indicated the chemical elevated enzyme activities of la...
