  • Objectives The purpose of this study was to evaluate the effect of Jeopgolsan (JGS) extract on anti-oxidant, anti-inflammatory activities in RAW 264.7 cells and on factors related with fracture healing in skull fractured rat. Methods Experimental animals were divided into four groups: normal group without any treatment (Normal), contral group were treated orally with distilled water (Control), Experimental group were treated orally with JGS at a concentration of 200 mg/kg/day (JGS 200) and Experimental group were treated orally with JGS at a concentration of 200 mg/kg/day (JGS 400). Rats in each group except the normal group were induced fractures in the skull. The 1,1-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical scavenging activity were measured to evaluate antioxidant activity. The production of nitric oxide (NO), $interleukin-1{\beta}$ ($IL-1{\beta}$), interleukin-6 (IL-6) and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) in the RAW 264.7 cells were measured to evaluate anti-inflammatory activity. The production of osteocalcin calcitonin, carboxy-terminal telepeptides of type II collagen (CTX II), transforming growth $factor-{\beta}$ ($TGF-{\beta}$), bone morphogenetic protein-2 (BMP-2), Insulin and alkaline phosphatase (ALP) in serum of rats were measured to evaluate the effects of fracture healing at 0, 2, 4, and 6th week. X-rays were taken every 3 week from 0 to 6th week to evaluate fracture healing effect. Results 1. No cytotoxicity was observed. 2. DPPH and ABTS radical scavenging activity were increased in a concentration dependent manner, indicating anti-oxidant effect. 3. NO, $IL-1{\beta}$, IL-6, and $TNF-{\alpha}$ were not significantly changed, indicating no anti-inflammatory effect. 4. Osteocalcin, Calcitonin, $TGF-{\beta}$ and ALP were significantly increased in the experimental groups. 5. CTX II, insulin were significantly decreased in the expermental groups. 6. Radiologic examination showed that union of fracture was promoted. Conclusions From above results, JGS showed significant results in factors related with fracture healing and radiologic examination. Threfore, JGS is expected to be effective in the treatment of fracture.

  • Transforming growth $factor-{\beta}\;(TGF-{\beta})$ has been shown to have a positive effect on in vitro fertilization (IVF) and has been reported to stimulate meiosis at follicular level in variety of species. The study was designed to determine the expression patterns of $TGF-{\beta}1,\;TGF-{\beta}$ receptors type I, II and Smads gene in bovine oocytes and embryos. $TGF-{\beta}1$ and their receptors were observed in the unfertilized oocytes. $TGF-{\beta}1$ and type II receptor were not expressed at the blastocyst stage, however, only type I receptor was exclusively observed at the same stage. The blastocyst stage, in particular, showed high levels of mRNA expression patterns containing a $TGF-{\beta}1$ type I receptor. The mRNA expression pattern of Smad 2 at all stages of embryonic development was similar in all respect with $TGF-{\beta}1$ type I receptor. On the contrary, Smad 3 and 4 were expressed with high and low level mRNA at the blastocyst stage. In conclusion. it is suggested that $TGF-{\beta}1$ signaling may be regarded as an important entity during the preimplantation embryo development.

  • In order to examine the immunoresponse of host cells to Enterococcus faecalis, this in vitro study monitored the production of Interleukin-2 (IL-2), Interleukin-4 (IL-4) and Transforming growth factor-$\beta1\;(TGF-\beta1)$ in human lymphocytes. Lymphocytes were activated with PHA in the presence or abscence of sonicated extracts of E. Faecalis (SEF) and further incubated for 72 hours. The level of each cytokine was measured by ELISA. Data were analyzed with Kruskal-Wallis test and Mann-Whitney U test (P < 0.05). PHA-activated group did exhibit higher level of IL-2 and IL-4 than untreated control group. The levels of expression of both cytokines were significantly decreased following the treatment of high (25 ${\mu}g/ml$) and medium concentration (12.5 ${\mu}g/ml$)) of SEF (P > 0.05) than those of PHA activated group. But low concentration (5 ${\mu}g/ml$)) of SEF showed th similar level of IL-2 and IL-4 production as those of PHA activated group. $TGF-\beta1$ was unaffected by SEF treatment. These results suggested that E. faecalis may suppress IL-2 and IL-4 production by lymphocytes and this could be one of possible factors why E. faecalis are found frequently in the teeth with failed endodontic treatment.

  • Minerals from marine materials such as deep ocean water and Dead Sea water have been used since ancient times. We made a mask pack sheet including deep ocean water and salt from the Dead Sea and evaluated the function of the mask pack sheet through animal study. Three full-thickness skin defects were made on the backs of Sprague-Dawley rats. The wounds were left untreated in group Con, and mask pack sheets including deep ocean water or deep ocean water and Dead Sea water were used as treatment for 20 min on the skin of animals in groups DP and DDP, respectively. We analyzed the gross, histological and biochemical findings. Groups DDP and DP showed decreases in wound size, as compared to group Con at 7 days after wound infliction. The histological findings revealed that wound healing had progressed further in groups DP and DDP than in group Con, with more rapid collagen deposition and regression of neutrophils. Also, the expression of vascular endothelial growth factor and transforming growth factor ${\beta}1$ were increased in groups DDP and DP compared with those in group Con at 3 days after wound infliction. Mask sheet packs including deep ocean water and Dead Sea salt affected wound healing by reducing the inflammatory phase and stimulated wound contracture by facilitating the deposition of collagen.

  • We aimed to investigate any association between hepatitis C virus (HCV) infection and non-Hodgkin's lymphoma (NHL) in the view of cytokines that control inflammation/angiogenesis and their correlation with certain CD markers. NHL patients with or without HCV infection were studied. CD5, CD30, CD3, CD20 and CD45 were immunohistochemically evaluated. Plasma levels of vascular endothelial and platelet derived growth factors (VEGF, and PDGF), tumor necrosis factor (TNF-${\alpha}$), transforming growth factor (TGF-${\beta}$), interleukin-6 (IL-6), IL-8, IL-4, IL-12 and interferon gamma (IFN-${\gamma}$) were detected by enzyme-linked immunosorbent assay (ELISA). HCV+ve NHL patients showed a significant reduction in VEGF, PDGF, IFN-${\gamma}$, CD5 and CD45 and a significant increase in IL-12 and IL-8. In conclusion, there was a significant change in cytokine secretion and expression of CD markers in HCV+ve NHL patients. Based on our results, HCV infection in NHL patients requires more in-depth investigations to explore any role in lymphoma progression.

  • This study was performed to evaluate regenerative effects of intrasplenic stem cell transplantation after partial hepatectomy. To evaluate the regenerative effects, Sprague Dawley rats were used. In vivo the embryonic stem cells of blastocysts were collected from superovulated rats on day 3.5 after the vaginal plug checked. The embryonic stem cells were cocultured with hepatocytes for 8 days, they were transplanted into the spleen. After the intrasplenic transplantation of cultured stem cells, they were initially distributed near the periarterial lymphatic sheath after transplantation in the hematoxylin-eosin staining. Their number were formely increased and their size enlarged at forming small lobules. The embryonic stem cells in the culture proliferated and initially proliferated around the periarterial lymphatic sheath and later they around the trabecula with blood vessels. After the transplantation of stem cells, their cell organelles were well developed rough endoplasmic reticulum at the 20th with prominent epidermal growth factor reaction, developed smooth endoplasmic reticulum at the 30th day, well differentiated bile canaliculi with increased transforming growth factor-$\beta$ and apoptosis reactions.

  • Objective: In humans, polycystic ovary syndrome (PCOS) is an androgen-dependent ovarian disorder. Aberrant gene expression in folliculogenesis can arrest the transition of preantral to antral follicles, leading to PCOS. We explored the possible role of altered gene expression in preantral follicles of estradiol valerate (EV) induced polycystic ovaries (PCO) in a mouse model. Methods: Twenty female balb/c mice (8 weeks, 20.0±1.5 g) were grouped into control and PCO groups. PCO was induced by intramuscular EV injection. After 8 weeks, the animals were killed by cervical dislocation. Blood serum (for hormonal assessments using the enzyme-linked immunosorbent assay technique) was aspirated, and ovaries (the right ovary for histological examinations and the left for quantitative real-time polymerase) were dissected. Results: Compared to the control group, the PCO group showed significantly lower values for the mean body weight, number of preantral and antral follicles, serum levels of estradiol, luteinizing hormone, testosterone, and follicle-stimulating hormone, and gene expression of TGFB1, GDF9 and BMPR2 (p<0.05). Serum progesterone levels were significantly higher in the PCO animals than in the control group (p<0.05). No significant between-group differences (p>0.05) were found in BMP6 or BMP15 expression. Conclusion: In animals with EV-induced PCO, the preantral follicles did not develop into antral follicles. In this mouse model, the gene expression of TGFB1, GDF9, and BMPR2 was lower in preantral follicles, which is probably related to the pathologic conditions of PCO. Hypoandrogenism was also detected in this EV-induced murine PCO model.

  • Background: Panax ginseng is regarded as one of the best compounds for promoting health, and it has been used traditionally as a medicinal herb. Recently, Korean Red Ginseng (RG) has been shown to protect skin from aging and wrinkling; it can also relieve atopic dermatitis and allergy symptoms. This study aimed to evaluate RG's effects on the regeneration of the full-thickness skin wounds in rat. Methods: Full-thickness skin wounds were generated in rats, and then RG was administered either orally or topically. The wound-healing effects of RG were investigated by assessing wound size, mRNA expression patterns of genes related to wound healing, histological staining, and measurements of lipid, moisture, and elasticity in skin tissues. Results: The wound size was smaller, and tissue regeneration rate was faster in the RG-treated group than that in the control group on days 15 and 20 after initiating treatment. On postoperative day 20, skin lipid and moisture content had increased significantly in the RG-treated group. Significant increases in the gene expression levels of transforming growth $factor-{\beta}1$ and vascular endothelial growth factor were found in the RG group during the early stages of wound healing. Matrix metalloproteinase-1 and matrix metalloproteinase-9 showed significant increases in gene expression levels on day 20. Conclusion: The results suggested that RG may promote healing of full-thickness skin wounds in rats. They also provided basic insights into the effects of RG on skin regeneration, supporting its use as a dressing material for wound treatment and its development as a functional food.

  • Objective : The aim of this study is to determine the association between the cerebrospinal fluid (CSF) biomarkers and inflammation, and the predictive value of these CSF biomarkers for subsequent shunt associated infection. Methods : We obtained CSF samples from the patients with hydrocephalus during ventriculoperitoneal (VP) shunt operations. Twenty-two patients were enrolled for this study and divided into 3 groups: subarachnoid hemorrhage (SAH)-induced hydrocephalus, idiopathic normal pressure hydrocephalus (INPH) and hydrocephalus with a subsequent shunt infection. We analyzed the transforming growth factor-${\beta}1$, tumor necrosis factor-${\alpha}$, vascular endothelial growth factor (VEGF) and total tau in the CSF by performing enzyme-linked immunosorbent assay. The subsequent development of shunt infection was confirmed by the clinical presentations, the CSF parameters and CSF culture from the shunt devices. Results : The mean VEGF concentration (${\pm}$standard deviation) in the CSF of the SAH-induced hydrocephalus, INPH and shunt infection groups was $236{\pm}138$, $237{\pm}80$ and $627{\pm}391$ pg/mL, respectively. There was a significant difference among the three groups (p=0.01). Between the SAH-induced hydrocephalus and infection groups and between the INPH and infection groups, there was a significant difference of the VEGF levels (p<0.01). However, the other marker levels did not differ among them. Conclusion : The present study showed that only the CSF VEGF levels are associated with the subsequent development of shunt infection. Our results suggest that increased CSF VEGF could provide a good condition for bacteria that are introduced at the time of surgery to grow in the brain, rather than reflecting a sequel of bacterial infection before VP shunt.

  • Transforming growth factor (TGF) family is well known to induce the chondrogenic differentiation of mesenchymal stem cells (MSC). However, the precise signal transduction pathways and underlying factors are not well known. Thus the present study aims to evaluate the possible role of C2 domain in the chondrogenic differentiation of human mesenchymal stem cells. To this end, 145 C2 domains in the adenovirus were individually transfected to hMSC, and morphological changes were examined. Among 145 C2 domains, C2 domain of protein kinase C eta ($PKC{\eta}$) was selected as a possible chondrogenic differentiation factor for hMSC. To confirm this possibility, we treated $TGF{\beta}3$, a well known chondrogenic differentiation factor of hMSC, and examined the increased-expression of glycosaminoglycan (GAG), collagen type II (COL II) as well as $PKC{\eta}$ using PT-PCR, immunocytochemistry and Western blot analysis. To further evaluation of C2 domain of $PKC{\eta}$, we examined morphological changes, expressions of GAG and COL II after transfection of $PKC{\eta}$-C2 domain in hMSC. Overexpression of $PKC{\eta}$-C2 domain induced morphological change and increased GAG and COL II expressions. The present results demonstrate that $PKC{\eta}$ involves in the TGF-${\beta}3$-induced chondrogenic differentiation of hMSC, and C2 domain of $PKC{\eta}$ has important role in this process.
