Objectives: The aim of this study was to investigate the safety and the efficacy of Korean herbal, western and combination medicine use in patients with abnormal liver function tests. Methods: We investigated nerve disease patients with abnormal liver function tests who were treated with Korean herbal, western and combination medicine at Dong-Eui University Oriental Hospital from January 2011 to August 2011. We compared aspartic aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and total bilirubin (T-bil) levels before and after taking medicine and excluded patients who had liver-related disease when admitted. Results: AST and ALT were decreased significantly in patients who had taken herbal, western medicine. AST, ALT and ALP were decreased significantly in patients who had taken combination medicine. Compare to herbal medicine, AST, ALT and ALP were decreased significantly in patients who had taken western medicine, and ALT and ALP were decreased significantly in patients who had taken combination medicine. There were no significant differences between western and combination medicine. Conclusions: This study suggests that prescribed Korean herbal medicine, at least, does not injure liver function for patients', moreover, it was shown to be effective in patients with abnormal liver function tests.

Effects of restraint stress and its modulations by ursodeoxycholic acid(UDCA) were evaluated on some biochemical and biophysical parameters in rats. Restraint stress induced elevations in blood alkaline phosphatase (ALP). cholesterol (CHOL), aspartate transaminase (GOT), alanine transaminase (GPT), lactate dehydrogenase (LDH) levels. It was also caused adrenal hypertrophy, decrease in weight of spleen and contents of ascorbic acid in stressed rats. As a results, stress indicators such as spleen, ascorbic acid, GOT, GPT, LDH were fastly changed after imposing stress, but those such as ALP, CHOL, adrenal were induced relatively later. UDCA was tested if it has an inhibitory effect against 18-hr restraint induced stress. UDCA lowered ALP, CHOL, LDH level and also effectively elevated the ascorbic acid contents in 25 mg/kg dosage of UDCA. In organ weights. the restraint stress induced increases in spleen and adrenal were attenuated by UDCA in 50 mg/kg dosage. However. stress-induced GOT and GPT levels were unaffected by UDCA.

Orthodontic force is a mechanical stress controlling both of tooth movement and skeletal growth. The mechanical stress stimulate bone cells that may exert some influence on bone remodeling. The purpose of this study was to evaluate the difference in cellular activity depending on mechanical stresses such as compressive and tensile force by determining the alkaline phosphatase(ALP) activity. A clonal osteogenic cell line MC3T3-E1 was seeded into a 24-well plate($2{\times}10^4/well$). At the confluent phase, a continuous compressive hydrostatic pressure($25g/cm^2$, $300g/cm^2$) and continuous tensile hydrostatic pressure($-25g/cm^2$, $-300g/cm^2$) were applied for 4, 6, 10, 14, 18, 20 days respectively by a diaphgragm pump. At the end of the stimulation period, cell layers were prepared for ALP activity assay. The ALP activity of the compressive group increased more than that of the tensile group at same force magnitude, whereas the cells responded to a similar pattern regardless of the type of mechanical stress The ALP activity of the compressive and tensile group turned into the level of the control group as the length of time increased. These results indicated that a mechanical stress may be more effective on cellular activity during active cellular proliferation and differentiation periods. The time to achieve maximum ALP activity was delayed as the mechanical stress increased in both the compressive and the tensile group. Accordingly, the magnitude of the stress rather than the type of mechanical stress may have more influence on cellular activity.

This study was done to investigate the enzyme-histochemical localization and characteristics of alkaline and acid phosphatase related with metabolism in sparganum and adult of Spirometrn erinacei. By the enzyme-histochemical assay, the alkaline and acid phosphatases were localized in the tegument and subtegumental musculature of sparganum and adult, but not in the parenchyma. The activities of alkaline phosphatase were stronger in the tegument than in the subtegumental musculature, and activities of acid phosphatase were stronger in the tegument of adults than those of sparganum. The 2 isozymes of alkaline and acid phosphatases were separated from s-sparganum (from snake) and r-sparganum (from experimentaly infected rats) respectively but 4 isozymes of Alp and 3 isoxymes of Acp were separated from adult worms by electrophoresis. In isogyme Alp, the 661)a was the common isozyme, but 130 kDa isozyme of Acp was the common isozyme in spargana and adult worms. By isoelectrofocusing, 4 isozymes (PI 7.9, 7.7, 6.5 and 6.3) and 2 isozymes (PI 7.9 and 7.7) of alkaline phosphatase were separated from adults and spargana respectively. In the stability against heat, activity of alkaline phosphatase was denatured perfectly after heating at 90℃ for 40 seconds. The optimum pH and temperature for activity of alkaline phosphatase were about pH 10 and 50℃, respectively. The maximum activity (unit) of alkaline phosphatase was 22.0 in s- sparganum,25.0 in r-sparganum and 215.0 in adult worms, so that the maximum activity was revealed higher in adults than spargana. As the result from above, we observed that alkaline and acid phosphatases were functioned mainly in the tegument and subtegumental musculature , and the isoxymes of phosphatase were activated differently according to habitat of the parasites. The spargana and adult worms carry out the pafasitism by adapting thenlselves to parasitic circumstance loth these emxymes.

The purpose of this study is to compare the properties of dental pulp and periodontal ligament stem cells from extracted supernumerary teeth by quantitative real-time PCR. Impacted supernumerary teeth in the maxillary anterior region were extracted. Dental pulp and periodontal ligament cells were collected from extracted supernumerary teeth on the same day. After isolation and culture of cells, compare characterization of them by using qRT-PCR. Primer sequences for odontoblasts are ONT, ALP, OCN, DMP-1 and DSPP. On dental pulp group, ONT has the largest quantity of gene expression, followed by OCN, ALP, DMP-1 and DSPP. On periodontal ligament group, ONT has the largest quantity of gene expression, followed by OCN, ALP, DSPP and DMP-1. Analysis of quantitative gene expression data using relative quantification showed that the expression of all genes decreased in periodontal ligament cells. Dental pulp and periodontal ligament stem cells from supernumerary teeth have the properties of odontoblasts. Considering that properties, supernumerary teeth were considered a useful donor site of dental pulp and periodontal ligament stem cells.

Objectives: The effects of bone morphogenetic protein-2 (BMP-2) and enamel matrix derivative (EMD) respectively with mineral trioxide aggregate (MTA) on hard tissue regeneration have been investigated in previous studies. This study aimed to compare the osteogenic effects of MTA/BMP-2 and MTA/EMD treatment in MC3T3-E1 cells. Materials and Methods: MC3T3-E1 cells were treated with MTA (ProRoot, Dentsply), BMP-2 (R&D Systems), EMD (Emdogain, Straumann) separately and MTA/BMP-2 or MTA/EMD combination. Mineralization was evaluated by staining the calcium deposits with alkaline phosphatase (ALP, Sigma-Aldrich) and Alizarin red (Sigma-Aldrich). The effects on the osteoblast differentiation were evaluated by the expressions of osteogenic markers, including ALP, bone sialoprotein (BSP), osteocalcin (OCN), osteopontin (OPN) and osteonectin (OSN), as determined by reverse-transcription polymerase chain reaction analysis (RT-PCR, AccuPower PCR, Bioneer). Results: Mineralization increased in the BMP-2 and MTA/BMP-2 groups and increased to a lesser extent in the MTA/EMD group but appeared to decrease in the MTA-only group based on Alizarin red staining. ALP expression largely decreased in the EMD and MTA/EMD groups based on ALP staining. In the MTA/BMP-2 group, mRNA expression of OPN on day 3 and BSP and OCN on day 7 significantly increased. In the MTA/EMD group, OSN and OCN gene expression significantly increased on day 7, whereas ALP expression decreased on days 3 and 7 (p < 0.05). Conclusions: These results suggest the MTA/BMP-2 combination promoted more rapid differentiation in MC3T3-E1 cells than did MTA/EMD during the early mineralization period.

Secondary metabolites from the fruit body of Phellinus linteus were evaluated for their proliferative effect on human osteoblast-like cells. 3-[4,5-Dimethylthiazole-2-y1]-2,5-diphenyl-tetraxolium bromide (MTT) assay and alkaline phosphatase (ALP) activity assay were used to assess the effect those isolates on the human osteoblast-like cell line (Saos-2). Activity-guided fractionation led to the isolation of ALP-activating phenolic compounds through the extraction of P. linteus, solvent partitioning, and repeated silica gel and octadecyl silica gel (ODS) column chromatographic separations. From the result of spectroscopic data including nuclear magnetic resonance (NMR), mass spectrometry (MS), and infrared spectroscopy (IR), the chemical structures of the compounds were determined as 4-(4-hydroxyphenyl)-3-buten-2-one(1), 2-(3',4'-dihydroxyphenyl)-1,3-benzodioxole-5-aldehyde (2), 4-(3,4-dihydroxyphenyl)-3-buten-2-one (3), 3,4-dihydroxybenzaldehyde (4), and protocatechuic acid methyl ester (5), respectively. This study reports the first isolation of compounds 1-3 and 5 from P. linteus. In addition, all phenolic compounds stimulated proliferation of the osteoblast-like cells and increased their ALP activity in a dose-dependent manner ($10^{-8}$ to $10^{-1}\;mg/mL$). The present data demonstrate that phenolic compounds in P. linteus stimulated mineralization in bone formation caused by osteoporosis. The bone-formation effect of P. linteus seems to be mediated, at least partly, by the stimulating effect of the phenolic compounds on the growth of osteoblasts.

Paraquat is a useful nonselective herbicide widely used throught the world. However accidental or intentional ingestion of the herbicide cause fatal pulmonary injuring. But there is not suitable antidote of paraquat intoxication and therapeutic agents now be used are not effective. So, in this study we intended to evaluate the inhibitory effects of acetylmannan from Dioscorea batalas on paraquat toxicity. 100mg/kg acetylmannan from wild or cultured Dioscorea bataras was administered orally to male SD rats for 3 days and the administration time interval was 24hours. After one hour of final administration, 50mg/kg paraquat was administered intraperitonially. After 24 hours, the biochemical parameters of blood and tissues were examined. In paraquat treated groups, sGPT, BUN, creatinine, ALP levels were increased by 2 to 4 times of normal values. However in acetylmannan from wild Dioscorea batatas treated groups, sGPT, BUN, creatinine, ALP levels in blood and lung tissue were significantly decreased to normal levels. In acetylmannan from cultured Dioscorea batatas treated groups, BUN, creatinine were significantly decreased to normal values, but not in sGPT, ALP levels. Therefore, we concluded that acetylmannan from wild Dioscorea batatas can be used as an. antidote of paraquat toxicity.

Phenanthrene-induced changes in blood organic components. transaminase and ALP activities of Paralichthys oIivaceus were investigaled. The aim of this study was to obtain a holistic view of the toxic responses, and compensations of fish exposed to waterborne phenanthrene. Fish were exposed to 0, 0.5, 1, 2$\mu$M of phenanthrene for 4 weeks. The most noticeable changes were concentration-dependent increase in levels of blood GOT and GPT activities. At concentrations 1.0 and 2.0 $\mu$M of phenanthrene GOT, GPT and ALP enzyme activities in plasma were increased. Plasma albumin concentration was stable in phenanthrene-exposed fish, however, plasma total protein level was reduced significantly at the 4-week sampling points (2.0$\mu$M). Plasma glucose levels were found to be increased significantly over the cootrol throughout duration of the experiment with phenanthrene. Overall the results suggest that phenanthrene has the potential to alter some physiological functions in olive flounder.
