Serum levels of alkaline phosphatase (ALP) are widely used in the clinical diagnosis of hepatic diseases and the assessment of liver status. They also have epidemiological significance to be prospective risk factors for bone diseases, such as osteitis deformans, rickets, osteomalacia, hyperparathyroidism, healing fractures, and osteoblastic bone tumors. In the previous study, single nucleotide polymorphisms (SNPs) in several genes have been reported to be associated with serum levels of liver enzyme in American population. We aimed to confirm whether the genetic variation of RETNLB (resistin like beta) gene also influence the serum levels of liver enzyme in Korean population. We genotyped variants in or near RETNLB in a population-based sample including 994 Korean adults. Here, we performed association analysis to elucidate the possible relations of genetic polymorphisms in RETNLB gene with serum levels of liver enzyme. By examining genotype data of a total of 944 subjects in 5 hospital health promotion centers, we discovered the RETNLB gene polymorphisms are associated with serum levels of ALP. The common and highest significant polymorphism was rs736327 (${\beta}$=8.66, P=2.37E-05), rs7639070 (${\beta}$=8.56, P=3.24E-05) with ALP in all groups. Furthermore, the ALP was consistently associated with rs736327 (${\beta}$=10.40, P=5.23E-05), rs7639070 (${\beta}$=10.32, P=6.74E-05) in the male population. Consequently, we found statistically significant SNPs in RETNLB gene that are associated with serum levels of ALP. In addition, these results suggest that the individuals with the minor alleles of the SNP in the RETNLB gene may have elevated serum levels of ALP in the Korean population.
The purpose of this study was to determine the zinc status of preschool children in Ulsan. The study was conducted in 95 children aged 3 to 6 years by investigating the anthropometric indices and assessing the biochemical analysis. The blood was analysed to assess serum zinc and alkaline phosphatase. And a questionnaire for dietary intakes using 24-hr recall method were performed by mothers of 95 subjects. The dietary intakes of children were analysed to determine the prevalence of inadequate and excessive intakes of zinc with Dietary Reference Intakes for Koreans (KDRIs). WHL (Weight-Length Index) and Kaup index were used to define obesity. The overall prevalence of overweight and obese subjects were 14.7% and 6.3% by WHL, were 15.8% and 13.7% by Kaup index. The mean intakes of zinc by children aged 3${\sim}$5y and 6y were 5.5 ${\pm}$ 1.4 mg/d (75.7% RDA) and 6.7 ${\pm}$ 2.0 mg/d, respectively, that was the level exceeding the estimated average requirement (EAR) and the recommended intake (RI) of Korean Dietary Reference Intakes. Less than 1.3% and 7.9% of children had usual zinc intakes below EAR and RI of KDRIs, respectively. The percentages of children with intakes exceeding the tolerable upper intake level (UL) were 2.6%. The zinc nutritional status by biological assay was found that mean serum zinc and alkaline phosphatase (ALP) of total subjects were 64.0 ${\pm}$ 8.4 ${\mu}$g/dl and 72.8 ${\pm}$ 14.9 U/L, there was not a significant difference between boys and girls. The range of serum zinc level was 45${\sim}$89 ${\mu}$g/dl and children with a low serum zinc concentration by several cut-off points were 18.9${\sim}$55.8%, especially. Serum zinc level was positively correlated to the intakes of calorie, calcium, fiber, iron, zinc, zinc/kg and height (p<0.001). Serum ALP was positively correlated height, weight and WLI. The zinc intake of children aiso showed a positive correlation with height and weight. These results indicate that there were significant correlations between the zinc status and growth of preschool children. Preschool children in Ulsan have dietary zinc intakes that exceed the new DRIs. The present level of intake does not seem to pose a health problem, but if zinc intakes with fortified foods and supplements were considered, the amount of zinc consumed by children may become excessive.
Children and adolescents normally have higher Alkaline phosphatase levels than adults. This study was conducted to provide basic data about pediatric reference intervals for ALP. The data from the 2011 Korean National Health and Nutrition Examination Survey was used. Analysis was done for 847 Children and Adolescents (443 boys and 404 girls) aged 10 to 19. The method of p-NPP & EAE buffer was used to get the data. The highest ALP levels were found in boys aged 12 to 13, the reference interval being 653~1,518 IU/L; the levels decreased for those over 13 years old. In the case of girls, the highest ALP levels were found with those aged between 11 and 12, the reference interval being 463~1,598 IU/L; the levels decreased after 12 years of age. The mean difference in all age groups was statistically significant, except for those aged 10 to 11 and 11 to 12. Therefore, it is suggested that pediatric reference intervals should be divided into three groups according to gender. Complementing data about children and adolescents below 10 years old were not included in this study and will be much needed in the next trial.

Purpose : To investigate biochemical markers for osteosarcoma, activities of deoxyribocuclease(DNase), ribonuclease(RNase), 5'-nucleotidase, alkaline phosphatase and amylase were determined in the osteosarcoma tissue and serum of patients with osteosarcoma. Also studied were DNase, RNase in osteosarcoma tissue, isolating the enzymes from the sarcoma tissue and investigating the sarcoma specific enzymes. Materials and Methods : The experimental tissue and serum were obtained from twelve patients with osteosarcoma. The control group were obtained from the normal healthy tissue of the same patients. The tissue were centrifugalized to obtain extracts. The extracts were analized for the estimation of nucleic acid, protein contents and enzyme activities. And then each enzymes were isolated and analized by DEAE-cellulose chromatography and estimated for activities. Result : Activities of acid DNase, RNase, 5'-nucleotidase and alkaline phosphatase were significantly increased in osteosarcoma tissue. Neutral RNase in osteosarcoma tissue was shown to bo highly active, exhibiting secretory form of RNase inhibitor associated with the RNase was also increased. In the serum of patients with osteosarcoma, RNase activity was significantly increased. DEAE-cellulose column chromatographical analysis revealed that acid DNase was isolated as a single enzyme and neutral RNase as five isozymes in osteosarcoma tissue. Conclusion : The results indicated that combination of these enzymes could be used as markers for osteosarcoma. The results indicated that acid DNase and neutral RNase might play a role in genesis of sarcoma and suppression of sarcoma.
Objectives : To investigate the effect of Taxilli Ramulus (TR) extract on bone metabolism of ethanol-treated animal model. Methods : The changes of serum calcium, calcitonin, estrogen level, a1ka1ine phosphatase activity, osteocalcin, parathyroid hormone content and urine calcium level were observed with ethanol treatment for 60 days. The results were compared with an ethanol- TR extract double treatment group. Results : We observed increment of serum osteocalcin, parathyroid hormone content, alkaline phosphatase activity and urine calcium level by chronic ethanol feed and they were recovered to near normal level with Taxilli Ramulus extract treatment. Weight gain, serum calcium level, calcitonin and estrogen content were remarkably reduced with ethanol treatment and their levels were normalized by Taxilli Ramulus extract. Conclusions : These results showed that Taxilli Ramulus extract have the ability to recover to normal in the body an abnormal calcium metabolism process due to external factors. These results suggested that Taxilli Ramulus extract have preventive effects on calcium concentration loss and osteoporosis.

Objective: Intestinal alkaline phosphatase (IAP) maintains intestinal homeostasis by detoxifying bacterial endotoxins and regulating gut microbiota, and lipid absorption. Antibiotics administered to animals can cause gut dysbiosis and barrier disruption affecting animal health. Therefore, the present study sought to investigate the role of IAP in the intestinal environment in dysbiosis. Methods: Young male mice aged 9 weeks were administered a high dose of antibiotics to induce dysbiosis. They were then sacrificed after 4 weeks to collect the serum and intestinal organs. The IAP activity in the ileum and the level of cytokines in the serum samples were measured. Quantitative real-time polymerase chain reaction analysis of RNA from the intestinal samples was performed using primers for tight junction proteins (TJPs) and proinflammatory cytokines. The relative intensity of IAP and toll-like receptor 4 (TLR4) in intestinal samples was evaluated by western blotting. Results: The IAP activity was significantly lower in the ileum samples of the dysbiosis-induced group compared to the control. The interleukin-1 beta, interleukin-6, and tumor necrosis factor-alpha concentrations were significantly higher in the ileum samples of the dysbiosis-induced group. The RNA expression levels of TJP2, claudin-3, and claudin-11 showed significantly lower values in the intestinal samples from the dysbiosis-induced mice. Results from western blotting revealed that the intensity of IAP expression was significantly lower in the ileum samples of the dysbiosis-induced group, while the intensity of TLR4 expression was significantly higher compared to that of the control group without dysbiosis. Conclusion: The IAP activity and relative mRNA expression of the TJPs decreased, while the levels of proinflammatory cytokines increased, which can affect intestinal integrity and the function of the intestinal epithelial cells. This suggests that IAP is involved in mediating the intestinal environment in dysbiosis induced by antibiotics and is an enzyme that can potentially be used to maintain the intestinal environment in animal health care.

This study was to analyze the changes of levels of alkaline phosphatase before and after enucleation of jaw cysts combined with bone grafting, and to evaluate biochemically the effectiveness of the early detection of bone healing and infection as a prognostic marker. Eighteen patients (13 males, 5 females) with cystic lesions of the jaws were divided into two groups. The bone graft group underwent enucleation and bone graft. The control group underwent only enucleation. Both groups were measured levels of ALP before surgery, and plus-minus 4 weeks postoperatively. The more discriminating results were obtained in the bone graft group. The results were as follows : 1. Levels of ALP after enucleation of jaw cysts were decreased in all patients with and without bone graft. 2. The bone graft group showed more marked decrease in variation of levels of ALP than the control group.(p=0.008) This should be considered as a result of increased osteoblastic activity and new bone formation. 3. Such variation could be used as a prognostic marker for bone healing after cyst operation. In the cost/benefit ratio, measurement of ALP activity could be useful as a convenient procedure in routine clinical practice.

This study was performed to investigate the influence of mixtures of 0(control), 1, 2 and 3% ethanol and water respectively on growth and various blood parameters of growing broiler chicks. At the end of the 7 weeks' experiment, body weight gain in 1% ethanol group and liver weight in 3% ethanol group were significantly higher than those of control group. It was found that the levels of red blood cell, hemoglobin, hematocrit, and serum protein were within normal ranges. Serum GOT and r-GTP activities were significantly increased in 2 and 3% ethanol groups compared with those in control group. But serum CPT activity was slightily decreased in all ethanol groups. Serum LDH activity was increased in all ethanol groups compared with that In control group. Serum alkaline phosphatase was not affected by the ethanol. Serum glucose concentration in 3% ethanol group was significantly lower than that in control group.
There has been increasing interest in the value of using soybean to delay or reduce the tumor incidence. This study was undertaken to investigate the possible protective effects of soybean against hepatocarcinogenesis induced by DL-ethionine. Accordingly, we measured biochemical changes occurring in serum and liver of rats treated with DL-ethionine in the presence or absence of soybean. Male albino rats were fed a control diet containing the hepatocarcinogen, DL-ethionine, or the control diet plus soybean 30%, or the control diet plus soybean plus DL-ethionine 0.25% for three months and then returned to a control diet for up to nine months. Rats fed a control diet plus DL-ethionine showed a gradual decrease in liver DNA, RNA, total protein, and liver weight and enzyme activites of liver transaminases (GOT and GPT) and alkaline phosphatase over the 7-month study period. This was followed by a large increase in the liver parameters at the end of the $9^{th}$ month, except for 5'-nucleotidase and glucose-6-phosphatase that showed a large decrease. On the other hand, a gradual increase in the serum enzyme activities of GOT, GPT, 5-nucleotidase, alkaline phosphatase, and in the albumin/globulin (A/G) ratio is observed in the group of rats fed a control diet plus DL-ethionine compared to the control group over 8 months, and this was followed by a large increase in all serum parameters studied at nine-months. The administration of 30% soybean to the rat diet in addition to DL-ethionine maintained all parameters studied at near control values until the end of the $9^{th}$ month. This study suggests that soybean has a protective effect against the hepatocarcinogenesis induced by DL-ethionine.
