Purpose: To investigate IQGAP1 and IQGAP2 expression in hepatocellular carcinoma (HCC) and itsassociation with HCC clinicopathological characteristics and survival outcomes. Methods: IQGAP1 and IQGAP2 mRNA and protein were measured in HCC tissues, para-tumor tissues and normal tissues by RT-PCR and Western blotting. We further examined 150 HCC samples with adjacent para-tumor tissues and 11 normal specimens by immunohistochemistry to evaluate the correlation of IQGAP1 and IQGAP2 with clinicopathological features and prognosis. Results: IQGAP1 mRNA and protein were up-regulated while IQGAP2 mRNA and protein were down-regulated in human HCC tissues compared with para-tumor and normal liver tissues (p<0.05). IQGAP1 expression was higher in primary HCC (122/150, 81.3%) than matched adjacent tissues (30/150, 20%, p<0.001), whereas IQGAP2 was lower (31/150, 20.7% as compared to 112/150, 74.7%, P<0.001). Positive IQGAP1 expression correlated with larger tumor size (p=0.002), advanced TNM stage (p=0.002) and tumor differentiation (III and IV, p=0.034). Negative IQGAP2 expression was significantly associated with larger tumor size (p=0.009), multicentric tumor occurrence (p=0.01), advanced TNM stage (0.009) and tumor differentiation (III and IV, p=0.020). Survival analysis revealed that patients with either IQGAP1+ or IQGAP2-tumors had significantly reduced disease-free survival (p<0.001 and 0.006 respectively) and overall survival (p<0.001 for both). Multivariate analysis showed that IQGAP1/2 switch was an independent prognosis factor for disease-free survival (HR=2.824) and overall survival (HR=2.189). Conclusion: Positive IQGAP1 and negative IQGAP2 expression were closely correlated with tumor progression and could be used as adjunctive biomarkers to improve prognostication for HCC patients.
Objectives : Many studies have shown an association between serum lipid concentrations and psychologic characteristics. However, conflicting results have also been reported. This study was designed to find the relationship between serum lipid levels(cholesterol and triglycerides) and psychologic characteristics(impulsiveness, aggressiveness, depressiveness) in adolescents. Methods : Serum cholesterol concentration, serum triglycerides concentration, complete blood count, electrolytes, liver function test, and blood sugar level were measured by overnight fasting blood sampling and urinalysis was also conducted in 407 high school students. Impulsiveness level was measured by Barratt Impulsiveness Scale(BIS). Aggressiveness level was measured by Buss-Durkee Hostility Inventory(BDHI). Depressiveness level was measured by Beck Depression Inventory(BDI). Serum cholesterol was measured by standard enzymatic assay and serum triglycerides was measured by Boehringer Mannheim method. Results : 1) Low cholesterol group(<15 percentile) were found to have significantly higher BIS score than high cholesterol group(>85 percentile) in female. Female low cholesterol group were also found to have significantly higher motor impulsivity score, a subscale of BIS, than high cholesterol group. 2) High triglycerides group(>85 percentile) were found to have significantly higher BDI score than low triglycerides group(<15 percentile) in male and female separately. Especially, male high triglycerides group were also found to have significantly higher BIS and motor impulsivity score than low triglycerides group. Conclusion : These results support the previous hypothesis that serum lipid levels(cholesterol and triglycerides) affect human psychologic characteristics.
The development of an antibody labeling method with $^{99m}$Tc is important for cancer imaging. Most bifunctional chelate methods for $^{99m}$Tc labeling of antibody incorporate a $^{99m}$Tc chelator through a linkage to lysine residue. In the present study, a novel site-specific $^{99m}$Tc labeling method at carbohydrate side chain in the Fc region of 2 antibodies (T101 and rabbit anti-human serum albumin antibody (RPAb)) using dihydrazinophthalazine (DHZ) which has 2 hydrazino groups was developed. The antibodies were oxidized with sodium periodate to pro-duce aldehyde on the Fc region. Then, one hydrazine group of DHZ was conjugated with an aldehyde group of antibody through the formation of a hydrazone. The other hydrazine group was used for labeling with $^{99m}$Tc. The number of conjugated DHZ was 1.7 per antibody. $^{99m}$Tc labeling efficiency was 46-85% for T101 and 67∼87% for RPAb. Indirect labeling with DHZ conjugated antibodies showed higher stability than direct labeling with reduced antibodies. High immunoreactivities were conserved for both indirectly and directly labeled antibodies. A biodistribution study found high blood activity related to directly labeled T1 01 at early time point as well as low liver activity due to indirectly labeled T101 at later time point. However, these findings do not affect practical use. No significantly different biodistribution was observed in the other organs. The research concluded that DHZ can be used as a site-specific bifunctional chelating agent for labeling antibody with $^{99m}$Tc. Moreover, $^{99m}$Tc labeled antibody via DHZ was found to have excellent chemical and biological properties for nuclear medicine imaging.edicine imaging.
The Artemisia capillaris THUNB is a perennial herb that belongs to the family Compositae spp and probably the most common plant among the various herbal folk remedies being used in the treatment of abdominal pain, hepatitis, chronic liver disease, jaundice and coughing in Korea. Recently the biological and pharmacological actions of herb have been studied well such as antibacterial, antidiabetic and antitumor activities. This experiment was conducted to investigate antitumor and immunomodulatory effects of Artemisia capillaris extracts against Hepa-1c1c7 and Sarcoma 180 cancer cells in in vivo experimental tests. In in vivo experimental tests using 210 ICR mice, based on flow cytometry, CD3+, CD4+, CD8+ and TNF-${\alpha}+$ splenocytes were significantly (p<0.05) reduced in the Hepa-1c1c7 and Sarcoma 180 inoculated vehicle controls, HP and SP, compared to those of the intact vehicle control on both the $28^{th}$ day and the $42^{nd}$ day, respectively. These decreases of CD3+, CD4+, CD8+ and TNF-${\alpha}+$ cells induced by tumor inoculations were significantly (p<0.05) inhibited by mACH treatment regardless of the type of experiments and tumor cells inoculated. The results suggest that Artemisia capillaris methanol extracts have prominent antitumor effects on the cancer cell lines Hepa-1c1c7 and Sarcoma 180.

Protaetia Brevitarsis Seulensis(white grub) has been traditionally used as medicinal stuff to treat blood stasis, occlusion of menstruation, tetanus and liver cancer in Asian countries (Korea, Japan, China, Taiwan, India and Myanmar). Especially, Donguibogam, which is traditional korean medicinal book, described the white grub as traditional medicine to treat hepatic diseases and vascular disorders. The white grub has been considered as highly nutritional food. The major constituents of white grub are rich in protein, healthy fats, iron, calcium. Recent studies announced that white grub has hepatoprotective effect and anti-microbacterial effect. However, the immuno-enhancing effect of white grub extracts in RAW 264.7 macrophage cells has not been studied yet. In this study, the various concentrations of white grub extract were examined to find immuno-enhancing effects on RAW 264.7 cells. Cytotoxicity was determined by MTT assay and immuno-enhancing effect of white grub extract was investigated by measuring nitric oxide (NO) production compared with only lipopolysaccharide (LPS) treatment. White grub extracts (0.001 - 10 mg/ml) did not show cytotoxicity. Additionally, white grub extracts (0.001 - 1mg/ml) had Immuno-enhancing effect on RAW 264.7 cells compared with only LPS treated group. These results might be provided proof to develop beneficial immuno-enhancing material for human health.
The fibrin sealant was first designed as an alternative to surgical suture for the purpose of surface-to-surface union especially in parenchymal organs like the liver, spleen and kidney. The clinical application of currently used fibrin sealant was first introduced in 1972. The fibrin sealant consists of principal two components; lyophilized human fibrinogen and bovine thrombin. The fibrinogen component also contains coagulation factor XIII. A solution of aprotinin, an inhibitor of fibrinolysis is used to dissolve the fibrinogen and to provide the first component, and a solution of calcium chloride is also used to provide the second component. From July to December in 1990, during 6 months, we used fibrin sealant in the 28 patients of 33 various cases, in the following ways; supportive application of fibrin sealant after free autogenouse nerve graft for the repair of inferior alveolar nerve, facial nerve or accessory nerve, treament of hemangioma or lymphangioma to thrombosize and lead to the tumor shrinking, skin grafting to stimulate the adhesion and tissue repair, bone grafting in the patients of cleft alveolus, mandibular reconstruction or orthognathic surgery to facilitate the knitting of bone chips, tissue adhesion after tumor resection, radical neck dissection or flap reconstructions, and supportive adhesion of external auditory cannal after TMJ surgery via postauricular approach. No adverse effects were observed, none of the patients developed hepatitis or other blood transmitted disease, and the wound healing were acceptable.

Background and Aims: Dansamtongmek-tang (DSTMT) and Dansamsengmek-san (DSSMS) have been used for many years as therapeutic agents for the acute stage of cerebrovascular disease, hypertension and hyperlipidemia in Oriental medicine, but the effects of DSTMT and DSSMS on hyperlipidemia and safety for cell damage are not yet well-known. This study was done to investigate the effects of DSTMT and DSSMS on hyperlipidemia. Methods: In vivo test: after administering DSTMT and DSSMS to SHR and ICR occurred hyperlipidemia for 3 weeks, we analyzed body weight, cholesterol levels. TG, HDL-chol, LDL-chol, LDH in plasma, brain, liver and kidney tissue, and DNA by RT-PCR. In vitro test: after administering DSTMT and DSSMS to human hepatocellular carcinoma in hypoxia, we observed cell cohesion by light microscope, analyzed the inflow of Ca2+ by confocal laser scanning microscope and DNA by RT-PCR. Results: DSTMT significantly decreased the levels of triglyceride and increased the levels of HDL-cholesterol in SHR, and significantly decreased the levels of LDL-cholesterol and body weight and increased the levels of HDL-cholesterol in ICR. DSSMS significantly decreased body weight, total cholesterol levels, LDL-cholesterol, LDH and cardiac risk factor (CRE) in SHR and significantly decreased the levels of total cholesterol, triglyceride, LDL-cholesterol, LDH and CRF in ICR. DSTMT had an effect on protecting cells from damage by inhibiting production of p53 mRNA, and in DSSMS, by inhibiting production of p53 mRNA and p21 mRNA after hypoxia. DSTMT effectively blocked off Ca2+ at low density, but DSSMS effectively blocked off Ca2+ at high density. Both DSTMT and DSSMS had an effect on inhibiting lipid metabolism by blocking off production of apo B mRNA. Conclusions: These results suggest that DSTMT and DSSMS might be usefully applied for treatment of hyperlipidemia and suppression of brain damage.

Hepatocellular carcinoma (HCC) is one of the most commonly diagnosed cancers in the word. Although radiation and chemotherapy are generally effective, there are various side effects that greatly limit the effectiveness of these treatments. Therefore, traditional herbs may have potential as important resources for the discovery of liver cancer therapeutics. In this study, we selected three Korean herbal medicine formulas from the Donguibogam, namely Bigihwan (BGH), Daechilgithang (DCGT), and Mokwhyangbinranghwan (MHBRH), and evaluated their anti-cancer effects on HCC cells. According to our results of three ethanol extracts, BGH was more effective at suppressing HCC growth than DCGT or MHBRH. Furthermore, flow cytometry analysis showed that inhibition of HCC proliferation by the three extracts was associated with the induction of apoptosis and autophagy. In particular, BGH significantly increased mitochondrial impairment and showed the possibility of inducing mitophagy in comparison with the other two extracts. BGH prominently upregulated the levels of microtubule-associated protein light chain-3 which was accompanied by a decrease in the expression of anti-apoptotic Bcl-2 without altering the expression of pro-apoptotic Bax. In addition, the levels of PTEN-induced kinase 1 were also markedly increased in BGH-treated HCC cells. Moreover, autophagy blocking improved cell viability and reduced apoptosis after the three treatments, indicating that autophagy by these extracts enhances HCC cells against cytotoxicity. In conclusion, our findings show that BGH demonstrates the highest anti-cancer activity among the three formulas and inhibits the proliferation of HCC cells through autophagy induction.
Apoptosis is a physiologic or programmed cell death process which is controlled by genes. It is essential for the function and the appropriate development of multicellular organism. It is also thought to be one of the main mechanisms of cell death in ischemic tissues. The effect of prostaglandin $E_1$($PGE_1$) is proven to be useful in the recovery of ischemic changes by inducing vasodilation of peripheral vessels and platelet disaggregation. $PGE_1$ is also known to suppress apoptosis in human liver sinusoidal endothelial cell from ischemia-reperfusion injury. The purpose of this study is to evaluate the effects of $PGE_1$ on the apoptosis in the ischemia reperfusion injury of rat intestine. Thirty Sprague-Dawley rats were used. In control group(N=15), superior mesenteric artery was occluded for 60 minutes and after removing the vessel clamp, it was reperfused for 60 minutes and harvested. In experimental group(N=15), a jejunal flap was also made as in the control group except for the intraarterial administration of the $PGE_1$ right after clamping the artery and removing the clamp. H&E, TUNEL and immunohistochemical stains for p53, bax, and bcl-2 were performed. There were ischemic changes in gross and microscopic findings in both groups. The apoptotic index was significantly lower in the experimental group($1.29{\pm}0.82$(p=0.003)) than in the control group ($2.33{\pm}0.95$). The rat intestinal ischemia apoptosis by ischemia-reperfusion was partly related to the modulating of bcl-2, bax, and p53 expression. Our results indicate that $PGE_1$ suppresses the apoptosis in the ischemic jejunal flap and this effect is probably the result of a increase in expression of bcl-2.
