Purpose: This study was conducted to analyze the clinical manifestation and natural course of benign transient hyperphosphatasemia (BTH) in children. Methods: A total of 17 children diagnosed with BTH between June 2006 and July 2007, were included in this study. Clinical records and laboratory tests were analyzed retrospectively for all children. Results: The mean age of the patients was $26.9{\pm}13.8$ months (range: 9 to 49 months). Nine of the 17 BTH cases (52.9%) occurred in patients that had previously suffered from infectious diseases. While the patients were suffering from BTH, the mean serum level of alkaline phosphatase (ALP) was $2,500.2{\pm}1,165.1$ U/L, however, these elevated serum ALP levels normalized within 7 weeks of recovery in all cases. In addition, a seasonal peak in the onset of BTH was observed from September to December. Further, the measurement of ALP isoenzymes in 7 of the patients with BTH, revealed a marked elevation of bone fraction. Conclusion: It is important for pediatricians to understand the clinical manifestation and benign course of BTH to avoid unnecessary diagnostic evaluation in children showing a transient increase in ALP activities.

Effect of Cheonnyuncho extract on the liver injury of rats treated carbon tetrachloride $(CCl_4)$ was studied. Cheonnyuncho extract was administerd at dose of 0.5 and 1 g/kg/day, p.o. for 2 weeks. $CCl_4$ was treated at dose of $0.5\;mL/kg$, i.p. 3 hours later from the last pretreatment of Cheonnyuncho extract. Administration of Cheonnyuncho extract at a dose of 1 g/kg decreased serum AST, ALT and ALP activities by 36, 41, and 22% respectively compared to $CCl_4$ treatment group. Increased lipid peroxidation and decreased SOD and GST activities were also recovered by pretreatment of Chonnyuncho extract in liver of rats. These results suggest that Cheonnyuncho extract has hepatoprotective effect against liver injury.

Panax ginseng C.A. Meyer (P. ginseng) is known to exert a wide range of pharmacological effects both in vitro and in vivo. Although studies on ginsenoside, antioxidant activity, and anticancer effect of the cultivated wild Panax ginseng (CWP) have been conducted, there is little research on the effect of CWP extract on bone metabolism. In this study, we investigated the potential anti-osteoporotic properties of CWP on the growth and differentiation of MC3T3-E1 cells. CWP significantly increased the viability and proliferation of MC3T3-E1 cells. CWP activated intracellular alkaline phosphatase (ALP) activity in MC3T3-E1 cells. In addition, CWP increased the mineralized nodules in MC3T3-E1 cells. Furthermore, CWP increased the expression of genes such as Runx2, ALP, OPN and OCN associated with osteoblast growth and differentiation in a dose-dependent manner.

This study was conducted to investigate the biochemical efforts of old antler extracts on the enzyme activities in serum of galactosamine (GaIN)-induced rats. Male rats of Sprague-Dawley strain weighing the average of 110$\pm$10g were divided into four groups and each group was fed either AIN-76 diet or modified AIN-76 diet with old antler extracts (water extract, neutral extract, ether extract) for four weeks. CaIN (400mg/ kg of body weight) was injected to CaIN treatment groups intraperitoneally on the same day every week. CaIN treatment decreased growth performance of rats. But dietary supplementation of old antler extracts prevented this decrement. Serum aminotransferase activities were increased by CaIN treatment, but this increment was reduced by feeding the old antler extracts, and the effect of water extract was the most prominent of the old antler extracts. Activities of lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) in serum of CaIN treatment groups were higher than those of control groups and were decreased by old antler extracts supplementation.

The present study was undertaken to determine the possible cellular mechanism of action of angiopoietin-2 in bone metabolism. The effects on the osteoblasts were determined by measuring 1) cell viability, 2) alkaline phosphatase (ALP) activity, 3) gelatinase activity, and 4) nitric oxide production. The effects on the osteoclasts were investigated by measuring 1) tartrate-resistant acid phosphatase (TRAP)(+) multinucleated cells (MNCs) formation, and 2) resorption areas after culturing osteoclast precursors. Angiopoietin-2 treatment showed a significant increase in both the viability and ALP activity of osteoblasts. Angiopoietin-2 increased the activity of gelatinase and nitric oxide production. In addition, angiopoietin-2 decreased the osteoclast generation induced by macrophage-colony stimulating factor (M-CSF) and receptor activator of NF-kB ligand (RANKL), and inhibited osteoclastic activity in (M-CSF)-dependent bone marrow macrophage (MDBM) cell cultures. Taken these results, angiopoietin-2 may be a regulatory protein within the bone marrow microenvironment.

Recently, many natural medicines, which have advantage of less side effects and possibility of long-term use, have been studied for their capacity and effects of anti-bacterial, anti-inflammatory and regenerative potential for periodontal tissues. Cortex Eucommiae, Eupoly phaga, Semen Cuscutae, Halloysitum Rubrum have been traditionally used as medicines for treatment of bone disease in Korea. The objective of the present study is to examine the ability of alkaline phosphatase (ALP) activity in human fetal osteoblast cell line (hFOB1) with several natural medicines. hFOB1 added DMEM/F-12 were cultured with dexamethasone as a positive control, and with each natural medicine. ALP activity was measured by spectrophotometer for enzyme activity and naphthol AS-Bl staining was performed for morphometry. All of the natural medicines induced a higher ALP activity compared to negative control, especially, Cortex Eucommiae increased an ALP activity in all experimental groups (p<0.05). In naphthol AS-Bl staining, all of the natural medicines of this study increased the stained area compared to negative control. Especially, Cortex Eucommiae and Eupoly phaga showed statistical significance compared to negative control (p<0.05). These results indicate that Cortex Eucommiae, Eupoly phaga, Semen Cuscutae, Halloysitum Rubrum have an inducing ability of ALP synthesis on osteoblasts.

The effect of orthodontic force on the collagenase and phosphatase activities of the adjacent alveolar bone was evaluated. Maxillary canines of male cats were treated orthodontically with closed coil spring so as to exert about 80g force. Sixteen cats were equally divided into one control group and seven experimental groups (12 hrs, 24 hrs, 36 hrs, 2 days, 3 days, 5 days and 7 days after orthodontic treatment). After sacrificing all animals on experimental intervals, collagenase, acid phosphatase (ACP) and alkaline phosphatase (ALP) activities were determined in the pressure and tension sides of alveolar bones. ACP activities increased in both the pressure and tension sides, but significantly increased in the pressure side continuously. ALP activities increased in the tension side at early stage (1-2 days after treatment), but changed small amount in the pressure side. Collagenase activities increased in the pressure side, especially at late stage (5-7 days after treatment). These results suggest that (1) orthodontic fore force increases the ACP, ALP and collagenase activities generally and (2) activities of ACP and collagenase increase in the pressure side, but that of ALP in the tension side and (3) activities of ACP and ALP increase at early stage, but that of collagenase at late stage after orthodontic treatment. Therefore it is shown that there are time differences in the formation and destruction of organic and inorganic components in the bone metabolism of alveolus with application of the orthodontic forces.

Several growth factors and polypeptides are not commonly yet used for regenerators of bone tissue or alveolar bone because of the insufficiency of studies on their side effects, genetic engineering for mass production and stability for clinical application. Recently, many herbal medicines, which have advantage of less side effects and possibility of long-term use, have been studied for their capacity and effects of anti-bacterial, antiinflammatory and regenerative potential of periodontal tissues. Morindae Radix, Cibotium Barometz (L.), Albizziae Cortex, Cistandhis Herba have been traditionally used as medicines for treatment of bone disease in Eastern medicine. The objective of the present study is to examine the ability of alkaline phosphatase (ALP) activity of human fetal osteoblast (hFOB1) when several natural medicines were supplemented. hFOB1 were cultured with Dulbecuo's Modified Eagle's Medium Nutrient Mixture F-12 HAM ( DMEM/F-12 1:1 Mixture, Sigma, USA) and negative control, dexamethasone (positive control), and each natural medicines for 3 days. And then ALP activity was measured by spectrophotometer for enzyme activity and Alizarin red S staining for morphometry. Among the natural medicines of this study, Morindae Radix, Cibotium Barometz (L.) and Cistanchis Herba induced higher activity of ALP synthesis than negative controls in all experimental group. Albizziae Cortex showed mild increases than negative control group. According to measurement of positively stained area, all of the natural medicines of this study increased compared to negative control. Especially, Cibotium Barometz (L.) and Cistanchis Herba showed statistical significance compared to negative control (p<0.05). These results indicate that Morindae Radix, Cibotium Barometz (L.), Albizziae Cortex, Cistandhis Herba have an inducing ability of ALP synthesis on osteoblast.

In this study, we intended to evaluate the modulatory effects of natural products, ${\beta}-carotene$, aloesin and semiessential amino acid, taurine on the toxicitiy of paraquat. In the taurine treated groups, serem glutamic oxaloacetic transaminase (s-GOT), serem glutamic pyruvic transaminase (s-GPT). blood urea nitrogen (BUN), creatinine, malondialdehyde (MDA), alkaline phosphatase (ALP) activity in serum and MDA, ALP activity, collagen in lung tissue were decreased to the normal values. In the aloesin treated groups, s-GPT, BUN, creatinine, MDA level in serum were decreased to the normal values significantly. In the ${\beta}-carotene$ treated group, only s-GPTactivity was reduced to the normal values. In the lung tissue of taurine treated groups, MDA value, G-6-phosphatase activity and collagen synthesis were recovered to the normal valuse and ALP activity was increase about 40%. From these results, we concluded that taurine is an effective agent to inhibit the pulmonary and internal organs toxicities induced by paraquat and the inhibition effects of taurine are due to remove free radicals directly.

This study was performed to confirm the antioxidative and hair-growth-promotion effects of a fermented compound composed of five materials, namely Allium cepa, Cucurbita spp., Glycine max Merr., Pinus sylvestris leaf, and Sesamum indicum. An additional compound composed of two materials was composed of Allium cepa and Cucurbita spp. Antioxidative effects were measured based on DPPH radical-scavenging activity and total flavonoid content. Fermented 5-type natural compounds (5NC) showed higher DPPH radical-scavenging activity and flavonoid content than those of fermented 2-type natural compounds (2NC). Hair-growth promotion was demonstrated in vivo. Alkaline phosphatase (ALP), oid contentontenteptidase phospactivity, and macroscopic observation were measured. Experimental animals were divided into four groups based on the samples they were administered: water, pansildil (P-CON), 5NC, and 2NC. Samples were administered orally once a day at a fixed time for four weeks. Both ALP and ${\gamma}eeksactivity$ increased in the 5NC group compared with the 2NC group. In macroscopic observation, the P-CON group grew the most and were most similar to the state before shaving. The 5NC group grew hair similar to the P-CON group. In all the results, the 5NC group showed greater antioxidative and hair-growth-promotion effects than the 2NC group. Consequently, 5NC could be used as an ingredient for hair-growth promotion.
