  • Gamijangsing-tang (GMJST) has been used for treatment of bone formation in traditional korean medicine. The purpose of this study is to examine effects of GMJST on bone metabolism. The effects on the osteoblasts were determined by measuring (1) cell proliferation, (2) alkaline phosphatase (ALP) activity, (3) osteoprotegerin (OPG) secretion. (4) The morphologic changes of cells were observed by light microscopy and electron microscopy. Mineralization of calcium was determined by quantitative alizarin red-S assay and mineralization of phosphate was observed by von kossa staining. The morphologic changes of mineralization on the cells were observed by transmission electron microscopy (TEM). The effects on the osteoclast were investigated by tartrate-resistant acid phosphatase (TRAP) staining. Following results were obtained: Celluar activity of osteoblastic cells (MG-63) was significantly increased in 10-5 of dilution of GMJST. ALP and OPG activity of osteoblastic cells were increased in GMJST than normal MG-63 cell. Mineralization of osteoblastic cells were increased in GMJST than normal MG-63 cell. The activity of osteoclast cells (RAW 264.7) was significantly decreased in GMJST than normal MG-63 cell. From the results, GMJST stimulated the proliferation and mineralization of bone-forming osteoblast and inhibited by bone- lysis osteoclast.

  • Experiments were undertaken to examine the ability of selenium to protect against alcohol and/or paraquat-induced hepatotoxicity and to examine the additive effect between alcohol and paraquat. Protective effect against hepatotoxic functions was measured in serum from alcohol(15% v/v), paraquat(200ppm), alcohol and paraquat, and combination of sodium selenite(4ppm) in drinking water-fed guinea pigs ad libitum for 4 weeks. A total of 68 healthy 7-weeks-old male animals were assigned at random to 8 treatment groups(9~13 animals/group). Body and liver weight losses, and high serum concentrations in aspartate aminotransferase(AST), alanine aminotransferase(ALT, in only paraquat group), $\gamma$-glutamyltranspeptidase($\gamma$-GTP), cholesterol(Cho), creatinine, blood urea nitrogen(BUN), total bilirubin(TB), direct bilirubin(DB), total protein(TP), albumin and globulin as well as low values in alkaline phosphatase(ALP) and glucose were produced in a groups of alcohol or paraquat-fed. These values were not potentiated in a group given the combination of alcohol plus paraquat. Morphological changes in the liver were also observed in the alcohol or paraquat-fed group. Lipid droplet and cell swelling in the hepatocytes were observed in alcohol-fed guinea pig, especially Mallory's hyaline arounded hepatic vein. In the paraquat-fed guinea pig, lipid droplet, pyknosis and karyolysis were observed. When alcohol or paraquat was combined with selenium-fed, hyperplasia of Kupffer cell in liver were observed. However, the mean ALT, $\gamma$-GTP, Cho, BUN, TB, TP, albumin and globulin values were lower in groups given the combination of alcohol and/or paraquat plus selenium, compared with groups given alcohol and/or paraquat. Also, the ratio of liver weight to body weight and ALP values(exception of paraquat plus selenium group) were increased by selenium. These results suggest that an adequate selenium confers marked protection against alcohol and paraquat-induced hepatotoxicity.

  • Effect of mixture of food material water extracts(modouri) composed of Job's tears, maize, buckwheat Japanese mushroom, lovage, licorice and jujube(13 : 50 : 15 : 2 : 5 : 5 : 5, v/v)] on the content of testosterone(T) and dihydrotestosterone(DHT), biochemical and histological changes of rat were investigated. Animal experiments(30 rats) were divided into 3 experimental groups(control, modouri and propecia). The summarized results were as follows: Activities of GOT, GPT, ALP, ${\gamma}$-GTP and content of total cholesterol and total lipid are normal in modouri group. Therefore modouri does not give rise to any damage in the liver. Also in the histological view, modouri does not have any hepatotoxic effect and increase the number of hair folicle. Total(T+DHT) and DHT content in rat serum and skin are significantly decrease in modouri group compare to the control but there is not any significant difference with propecia.

  • Chronic exposure to high levels of manganese (Mn) leads a pronounced and debilitating disorder known as manganism. Research on the toxic manifestation of manganese have focused primarily on its neurological effects because exposure to high levels of the metal produces a distinct and irreversible extrapyramidal dysfunction resembling the dystonic movements associated with Parkinson's physiological and biochemical systems in the body. The purpose of this study is to determine the effects of Mn on mineralization in primary rat calvarial cells. The experimental groups were in concentration of 0, 10, 30 and 60 ${\mu}M$. The results were as follows: 1. ALP activity was decreased in concentration of 30 and 60 ${\mu}M$ (p<0.01). 2. Bone nodule formation was depressed in concentration of 30 and 60 ${\mu}M$ at day 14 and 21 (p<0.01). 3. RT-PCR results showed an altered expression of bone matrix proteins. These result suggested that manganese might decrease or alter the expression of the osteoblast phenotype.

  • This study was performed to evaluate hepatoprotective effect of Daewhang-whangryunhaedok-Tang(DWT) on liver injured rats induced by $CCl_4$ and the acute oral toxicity of it in mice. The activities of serum transaminase(ALT/AST), alkaline phosphatase(ALP) and lactic dehydrogenase (LDH), the levels of serum total cholesterol(TC) and triglyceride(TG), change of liver enlargement, and inhibitory activities of lipid peroxidation, catalase and glutathione-S-transferase(GST) in liver microsome were determined in hepatotoxic rats induced by $CCl_4$ DWT DWT was significantly reduced the serum ALT, AST, ALP, LDH, TC and TG levels. And, the increase of lipid peroxidation, decrease of catalase and GST activities in the liver microsome of $CCl_4$-intoxicated rat were significantly improved by the treatment of DWT. Male and female mice were administered maximum dosages of 5,000 mg/kg b.w. of DWT. After single oral administration of DWT to mice, we observed them daily for 2 weeks. DWT did not induce any toxic signs in the mortalities, clinical signs, body weight changes, and gross necropsy findings of mice. Based on these results, it is concluded that DWT may have the hepatoprotective effect on $CCl_4$ induced hepatotoxicity in rats. Also, DWT may have no side effect and its $LD_{50}$ value may be over 5,000 mg/kg b.w. in mice.

  • Osteoporosis is recognized as one of the major hormonal deficiency diseases, especially in menopausal women and the elderly. When the estrogen level is reduced in the body, local factors, which are known to be related with bone resorption, are increased and promote osteoclastogenesis. In our previous study, we validated the estrogenicity of silkworm pupa. In this study, we investigated the effect of silkworm pupa extract (SPE) on the function of osteoblastic MC3T3-E1 cells. SPE (10 and $50\;{\mu}g/mL$) significantly elevated cell viability, alkaline phosphatase (ALP) activity, and collagen content in the cells. The effect of SPE ($50\;{\mu}g/mL$) in increasing cell viability, ALP activity, and collagen content was completely inhibited by the presence of $10^{-6}\;M$ of cycloheximide and $10^{-6}\;M$ of tamoxifen, suggesting that SPE's effect results from a newly synthesized, protein component and that it might be partly involved in estrogen action. Furthermore, we examined the effect of SPE on the $H_2O_2-induced$ apoptosis and production of local factors in osteoblasts. Treatment with SPE ($50\;{\mu}g/mL$) decreased the 0.2 mM $H_2O_2-induced$ apoptosis and the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and nitric oxide (NO) in osteoblasts. Our data indicate that the enhancement of osteoblast function by silkworm pupa may prevent osteoporosis and inflammatory bone diseases.

  • Despite the reports on safety concerns regarding the relationship between aluminum salts and neurological and bone disease, many countries continue to use aluminum as phosphate binders among patients with renal failure. In search for a diet supplement that could reduce aluminum toxicity related to renal failure, we carried out this prospective animal study in which the fenugreek seeds were assessed for their effects on rats nephrotoxicity induced by aluminum chloride ($AlCl_3$). Oral $AlCl_3$ administration during 5 months (500 mg/kg bw i.g for one month then 1600 ppm via drinking water) led to plasma biochemical changes, an inhibition of alkaline phosphatase (ALP), a decrease of total antioxidant status (TAS), and an induction of lipid peroxidation (LPO) in the blood and brain, in addition to kidney atrophy and morphological alterations at the level of Bowman's capsule, the glomerulus and different sorts of tubules, reminiscent of some known kidney disease. The treatment with the whole fenugreek seed powder (FSP) (5% in the diet) during the last 2 months showed its effectiveness in restoring normal plasma values of urea, creatinine, ALP and glucose, as well as re-increasing the TAS, inhibiting LPO and alleviating histopathological changes in the injured kidneys. This study highlights the induced nephrotoxicicity, as well as the related toxicity in the brain and bone, by chronic oral ingestion of the aluminum salts. However, the maintenance of a diet supplemented with fenugreek seeds could offer protection for the kidney, bone and brain, at the same time.

  • Objectives This study was performed to decide the bone union effect of Hwaweo-jeon on tibia fractured mice. Methods In this study, laboratory experiments were implemented by the stage of in vitro and in vivo. In in vitro, MC3T3-E1 cells were treated with various concentration of Hwaweo-jeon extract (HWJ). To investigate effect of HWJ for osteoblast, relative mRNA expression of 5 substances (alkaline phosphatase [ALP], runt-related transcription factor 2 [Runx2], osteocalcin [OCN], osterix [OSX] and collagen type II alpha 1 chain [Col2a1]) was used as a marker of osteogenesis. In order to determine HWJ's effect for fracture healing, relative gene expression level of ALP, Runx2, OCN, OSX and Col2a1 were used to find out the influence to osteoblast. Furthermore, receptor activator of nuclear factor kappa-B ligand and osteoprotegerin relative mRNA expression were used to estimate the impact to osteoclast. Also, X-ray was used for the purpose of identifying bone union in tibia-fracture mouse model. Results In in vitro experiment, most part of relative mRNA expression were increased compared to control group. In in vivo and in vitro experiment, HWJ induced osteoblast activitation by verifying relative mRNA expression of 5 substances. And in vivo experiment, we can also identify that HWJ triggered osteoclast activation during early stage of tibia fracture. Furthermore, X-ray pictures show noticeable recovery of tibia fracture. Conclusions HWJ extract promotes bone union by facilitating the osteoblast. But, HWJ may occur liver & kidney toxicity over specific concentration. Therefore, when HWJ is applied to human body, doctors have to follow up the liver function test & renal function test of patient.
