Glycyrrhizae Radix aqua-acupuncture solution (GRAS) and Glycyrrhizae Radix water-extracted solution (GRWS) were prepared and tested for organ toxicities, antitumor activities, and immunomodulatory effects. The organ-toxicity of GRAS to male ICR mice was studied by the measurements of glutamic oxaloacetic transaminase (GOT), glutamic pyruvate transaminase (GPT), lactate dehydrogenase (LDH), and alkaline phosphatase (ALP-s) activities after injection of GRAS for 7 days. The activities of GOT, GPT, LDH, ALP-s were decreased with GRAS. It was shown to possess considerable toxicity toward various tumor cell lines. Concentration of GRAS at 1.5g/ml and 3g/ml resulted in more than 80% inhibition of growth in Ehrlich ascites tumor cells (EATC), Hepa1c1c7, and HeLa cells. Toxicity of GRAS to A549 revealed that 68% inhibition of growth. GRWS at the concentration of 3g/ml showed more than 80% inhibition of growth with EATC, Hepalclc7, A549 and HeLa. In morphological study, the number of cells were decreased, and the shape of cells was round-form in EATC, Hepalclc7, A549 and HeLa cells with GRAS. Administration of GRAS inhibited the growth of EATC in vivo. Mice given EATC at 1.5g/ml or 0.3g/ml GRAS had 16.7% to 50% survival after 21 days. GRAS increased the proliferation of T and B cells and the cytolytic activity of purified T cell. The biosyntheses of nucleic acid and protein of EATC, Hepalclc7, A549 and HeLa cells were inhibited by GRAS.
To examine the effect of Saengshik on parameters related to hepatoprotective, anthropometric, blood pressure, serum lipid and blood related indices, nonalcoholic fatty liver subjects were treated with two meal portion of Saengshik in the replacement of meals for a period of three months. Weight, Body Mass Index (BMI) and systolic blood pressure were significantly decreased after the treatment. Chronically elevated serum aspartate aminotransferase (AST), gamma-Glutamyl transferase (r-GTP) and Alkaline Phosphatase (ALP) levels showed reduction to the near normal range. Serum total triglyceride level were reduced following the treatment. Whereas, there were no changes of serum total cholesterol with Saengshik consumption. Also, additional study was conducted to investigate the effect of Saengshik supplementation to high cholesterol and fat diet on lipid metabolism in rats. Male Spraque-Dawley rats were administrated hyperlipidemiainducing diet containing 1% cholesterol and 10% lard to induce hyperlipidemia for 4 weeks and were fed on diet containing Saengshik (30%, w/w) for 7 weeks. The feeding of diet containing 30% Shaengshik significantly decreased total cholesterol (TC) contents and total triglyceride. These results demonstrate Saengshik may be beneficial for fatty liver patients in improving their lipid metabolism.
Periodontitis is characterized by gingival inflammation and results in periodontal pocket formation with loss of the supporting alveolar bone and connective tissue around the teeth. Therapeutic modalities should therefore aim not only at eliminating the gingival inflammatory process and preventing the progression of periodontal disease but also at reestablishing and regenerating the periodontal tissue previously lost to the disease. To achieve periodontal regeneration, progenitor cells must migrate to the denuded root surface, attach to it, proliferate and mature into an organized and functional fibrous attachment apparatus. Likewise, progenitor bone cells must also migrate, proliferate, and mature in conjunction with the regenerating periodontal ligament. Significant advances have been made during the last decade in understanding the factors controlling the migration, attachment and proliferation of cells. A group of naturally occuring molecules known as polypeptide growth factors in conjunction with certain matrix proteins are key regulators of these biological events. Of these, the fibroblast growth factor(FGF), platelet-derived growth factor(PDGF) , insulin like growth factor(CIGFs), transforming growth factor(TGFs), epidermal growth factor(EGF) and bone morphogenetic growth factor(BMPs) apper to have an important role in periodontal wound healing. The purpose of this study was to determine the effects of BMP on periodontal ligament cells. Human periodontal ligament cells were cultured from extracted tooth for non-periodontal reason. Cultured periodontal ligament cells were treated with BMP. Cellular activities were determined by MTT(3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) assay and ALP(alkaline phosphatase) activity. The results were as follows ; Regardless of cultured time, cellular activities were stimulated by BMP. Also, BMP greatly increased alkaline phosphatase(ALP) in periodontal ligament cells. These results suggest that BMP not only have no cytotoxic effect on periodontal ligament cells, but also have osteogenic stimulatory effect on periodontal ligament cells.
To evaluate the effect of cyclohexane(CH) treatment on the serum levels of glutathion S-transferase(GST) activity in liver damaged animals, damaged liver was induced with pretreatment of 50% $CCl_4$ dissolved in olive oil (0.1 m1/100g body weight) intraperitoneally 17 times every other day. To $CCl_4$-treated rats, CH (1.56 g/kg body weight, i.p) was injected once and then the animals were sacrificed at 4 hours after injection of CH. The $CCl_4$-treated animals were identified as severe liver damage on the basis of liver functional findings, 1,e, increased serum levels of alanine aminotransferase(ALT), alkaline phosphate(ALP) and xanthine oxidase(XO) activities. On the other hand, $CCl_4$-treated animals injected with CH once($CCl_4$-pretreated animals) showed more decreased serum levels of ALT and XO, and more increased those of ALP rather than $CCl_4$-treated animals. In case of comparing the GST with ALT activity in liver, both $CCl_4$-treated and pretreated animals showed similar changing pattern of enzyme actvity. Especially $CCl_4$-pretreated animals showed significantly increased serum level of GST actvity compared with the $CCl_4$-treated those, whereas those of ALT showed reversed tendency. In aspects of GST enzyme kinetics, $CCl_4$-pretreated animals showed higher Vmax of liver GST enzyme than $CCl_4$-treated animals. In conclusion, injection of CH to the liver damaged rats led to enhanced liver damage and more increased activity of serum GST which may be chiefly caused by the enzyme induction.
Objectives: This study was aimed to find the effect of Samiunkyungtang on inflammation and microflora in an ulcerative colitis animal model. Methods: We established four groups of normal, control, test 1, and test 2 and assigned 6 rats toeach group. The normal group was not treated by any process and fed by normal saline. The control & test groups were provided with 4% dextran sodium sulfate (DSS) treatment for 7 days. Samiunkyungtang extract was orally administered to test groups (test 1=25mg/kg, test 2 100mg/kg) 3 days after DSS treatment for 10 days. After DSS treatment finished, we sacrificed the mice and measured colon length and enzyme activities such as myeloperoxidase (MPO), alkine phosphatase (ALP), ${\beta}$-glucuronidase, ${\beta}$-glucosidase, chondroitinase, and tryptophanase. Results: The colon lengths of test 1 and 2 groups were longer than the control group (p<0.05). Histologically, the crypts and superficial epitheliums of test 1 and 2 groups were regenerated. Goblet cells from all test groups were retrieved. The inflammatory biochemical marker, MPO and ALP activities in all test groups were highly reduced (p<0.01) compared to the control group. The activities of fecal bacterial enzymes in test groups such as ${\beta}$-glucuronidase, ${\beta}$-glucosidase, chondroitinase, and tryptophanase were reduced compared to the control group (p<0.01). Conclusions: As a result of this experiment, Samiunkyungtang is considered to have an inhibitory effect on inflammation and fecal enzyme activity in DSS-induced colitis animal model. Our results indicate that Samiunkyungtang may possess therapeutic effect on the development of DSS-induced colitis.
To apply the serum xanthine oxidase (XO) determining for the index of the toluene intoxication, the serum XO activity was compared with the other parameters, the activities of serum alanine aminotransferase(ALT), aspartate aminotransferase(AST), 5'-nucleotidase(5'-NT), alkaline phosphatase(ALP), guanase(GDA) and $\gamma$-gIutamyl transpeptidase(T-GTP). Concomitantly, the cause of increased level of serum XO was clarified in the present experimental conditions. Although the other serum enzyme activities, ALT, AST, 5'-NT, ALP, GDA and $\gamma$-GTP were respectively not found to be different between control group and toluene-treated group, the serum XO activity in toluene-treated group showed the higher levels than that in the control group. These suggested that the determination of serum XO activity could be used for monitoring the intoxication of toluene. On the other hand, the activities of XO both in the serum and liver were higher in toluene-treated or benzaldehyde-treated rats than those in each control group. In the pooled liver XO from each group, toluene-treated or benzaldehyde-treated group showed the higher $V_{max}$ value than the control group, whereas no changes were observed in liver XO activities between the control liver specimen and that preincubated with bertzaldehyde in vitro. The present results indicate that the increased level of XO in toluene-treated rats is due to the result of enzyme protein induction in liver cell by the benzaldehyde metabolized from toluene. All the more, the benzaldehyde may be acted as a substrate for XO, since the benzaldehyde induced the increased activity of both liver and serum XO, and no changes were found in purine catabolite, uric acid in serum or urine and liver purine catabolizing enzymes, adenosine deaminase, GDA, uricuse except XO in toluene-treated rats.
Objectives: This study was performed to evaluate the effect of Guibi-tang water extract (GB) on osteoporosis. Methods: We examined the effect of GB on osteoclast differentiation using murine pre-osteoclastic RAW 264.7 cells treated with receptor activator of nuclear factor kappa-B ligand (RANKL). The effect of GB on osteoclast was measured by counting TRAP (+) multinucleated cells and measuring TRAP activity. The mRNA expressions of osteoclastogenesis-related genes (Cathepsin K, MMP-9, TRAP, NFATc1, MITF, TNF-${\alpha}$, IL-6, COX-2) were measured by real-time PCR. We examined the effect of GB on osteoblast proliferation, ALP activity, bone matrix protein synthesis and collagen synthesis using murine calvarial cell. Results: GB decreased the number of TRAP (+) multinucleated cells and inhibited TRAP activity in RANKL-stimulated RAW 264.7 cell. GB decreased the expression of genes related osteoclastogenesis such as Cathepsin K, MMP-9, TRAP, NFATc1, MITF, COX-2 in RANKL-stimulated RAW 264.7 cell. But GB did not decrease the expression of iNOS and increased the expression of TNF-${\alpha}$, IL-6 in RANKL-stimulated RAW 264.7 cell. These genes (iNOS, TNF-${\alpha}$, IL-6) are thought to be related with the inflammatory bone destruction. GB increased cell proliferation of rat calvarial cell and also increased ALP activity in rat calvarial cell. GB did not increase bone matrix protein synthesis but increased collagen synthesis in rat calvarial cell. Conclusions: This study suggests that GB may be effective in treating osteoporosis by inhibiting osteoclast differentiation and its related gene expression and by increasing osteoblast proliferation.

To develop functional products based on black garlic, a black garlic extract (BG) of 7 brix, a gaeddongssuk extract (GS) of 0.7 brix and two types of mixtures (MBS-I, black garlic 7 brix : gaeddongssuk 0.7 brix; MBS-II, black garlic 14 brix : gaeddongssuk 1.4 brix, 93:7, v/v) were supplemented to rats training on a treadmill for 4 weeks. Body weight from the training did not decrease during the experimental period. Serum albumin content significantly increased in the groups fed an experimental diet compared to the control. The BUN content significantly decreased in BG and MBS-II groups compared to the control. AST and ALP activities significantly decreased in the groups fed an experimental diet compared to the control. Serum triglyceride and total cholesterol levels in MBS-I and MBS-II groups significantly decreased compared to the control. Lipid levels in the serum and liver tissue were not significantly different between the MBS-I and MBS-II groups. The lipid peroxide content in the serum and liver tissue was significantly reduced in the groups fed all extracts compared to the control; the serum and liver lipid contents was lowest in the MBS-I and MBS-II groups, respectively. Hepatic catalase activity in the GS and MBS groups increased by 1.8~2.3 times compared to the control. SOD and GSH-px activities significantly increased from treatment with the extracts by 1.3~1.5 times and 1.2~1.7 times, respectively. These results indicate that a mixture of BG and GS extracts has higher biological activity than a single supplementation of BG or GS extract. Therefore, the addition of gaeddongssuk to black garlic (MBS-I and MBS-II) is effective as a defense material against oxidative stress. MBS-I may be especially effective for its biological activities.
The purpose of this study were to determine that dexamethasone(Dex) induces differentiation of periodontal ligament(PDL) cells to osteoblastic cells and to investigate expression of matrix Gla protein(MGP), which is one of bone matrix protein. The isolated human PDL cells and gingival fibroblasts were prepared and cultured. The fourth or sixth sub-passage cells were used in this experiments. control group, ascorbic acid and ${\beta}$-glycerophosphate treated group, ascorbic acid, ${\beta}$-glycerophosphate and l00nM Dex treated group, ascorbic acid, ${\beta}$-glycerophosphate, and 5 ${\mu}M$ Dex treated group were made for study. The results were as follows: Cellular morphological change of PDL cells according to time was investigated. At first, the cells exhibited confluent monolayer of spindle or polygonal appearance. The multilayer of cells were seen after 7 days of treatment. After 14 days, the cells lost polarity and were densely packed. The mineralized nodule formation was seen at 21 days in the only Dex treated PDL cell groups. In the gingival fibroblast groups and no Dex treated PDL cell groups, the mineralized nodule was not seen. The mineralized nodule formation of 5 ${\mu}M$ Dex treated group was higher than 100 nM Dex treated group. Alkaline phosphatase(ALP) activity was higher in the Dex treated PDL cell groups of 14 and 21 days than 0 and 7 days. MGP was expressed in the control and all experimental groups and the expression was constant at 0,7,14,21 day. The above results confirm that Dex is affected to differentiation of the PDL cells to osteoblastic or cementoblastic cells and has dose-dependent effect for mineralization. And, MGP is expressed in the PDL cells and is not affected to mineralization of PDL cells.
