  • This study was investigated the effect of aerobic exercise and chrysin supplementation on macrophage infiltration and lipolysis in high-fat diet mice. To accomplish the purpose of this study, C57BL/6 mice were fed high fat diet(60% fat diet) during experimental period. The animals were divided into 4 groups; NC (normal diet control, n=5), HC (high fat diet control, n=5), Hch(high fat diet with chrysin, n=5), and HME (high fat diet with aerobic exercise training, n=5). Exercise training was performed for 16 weeks on a treadmill running. As a result, macrophage marker, F480 and CD11c were significantly decreased in HME comparison with HD and Hch. Also, M2 macrophage marker CD11c, and lipolysis marker PRDM were significantly increased in HME compared with HC and Hch These findings suggest that regular aerobic exercise has beneficial effects to inhibit macrophage infiltration in high fat diet mice.

  • In the previous paper (Kim et al., Glycoconjugate Journal 16, 247-252, 1999), heteropolysaccharides from Korean medicinal plant, Phellodendri cortex (Hwangbek) showed a poten B-Iymphocyte-stimulating activity in a system using polyclonal antibody forming cells in C57BL/6XC3H mice at dosages of 2-10 mg. In a series of biolgical active polysaccharides from natural medicinal plants, the polysaccharide fractions were isolated and purified from Phellodendron chinese SCHNEID, and antitumor activities were examined at dosages of 2, 5 and 10 mg/100 g. F-7 and F-8 showed the highest tumor inhibitory activities (inhibition ratio 96.4 and 98.2% in 2 mg/100 g), and in dose of 5 mg/100 g, the inhibitory ratios were 95.3 and 97.5%, respectively. Furthermore, 10 mg/100 g of intraperitoneal (i.p.) injection gave 97.3 and 98.7% of inhibition. In oral administration, the inhibitory activities were not markedly observed, indicating that the polysaccharides are directly acting to immune system. When the effects on TS and TK activities were determined, TS activities in the F-2 and F-7-treated mice were markedly suppressed to 73.7% and 79.5% of that in the control (p<0.01), while there was little difference in TK activity with a slight decrease in F-2 only. However, in i.p. injection, TS activities in the F-2, F-5, F-7 and F-8-treated mice were markedly suppressed to 83% to 85% of that in the control (p<0.01). Furthermore, there was also significant differences in TK activities in F-2, F-5, F-7 and F-8-treated mice (p<0.05). Therefore, polysaccharide fraction F-8 was further purified to active fractions of F-9 and F-11 by gel permeation chromatography using TSK Gel HW50S. The purified polysaccharides of F-9 and F-11 were composed of GlcNAc (47.3%), Gal (24.7%) and Man (28.0%). These results clearly indicated that the i.p. injection is much effective to suppress tumor growth than oral administration.

  • Fimasartan, a new angiotensin II receptor antagonist, reduces myocyte damage and stabilizes atherosclerotic plaque through its anti-inflammatory effect in animal studies. We investigated the protective effects of pretreatment with fimasartan on ischemia-reperfusion injury (IRI) in a mouse model of ischemic renal damage. C57BL/6 mice were pretreated with or without 5 (IR-F5) or 10 (IR-F10) mg/kg/day fimasartan for 3 days. Renal ischemia was induced by clamping bilateral renal vascular pedicles for 30 min. Histology, pro-inflammatory cytokines, and apoptosis assays were evaluated 24 h after IRI. Compared to the untreated group, blood urea nitrogen and serum creatinine levels were significantly lower in the IR-F10 group. IR-F10 kidneys showed less tubular necrosis and interstitial fibrosis than untreated kidneys. The expression of F4/80, a macrophage infiltration marker, and tumor necrosis factor $(TNF)-{\alpha}$, decreased in the IR-F10 group. High-dose fimasartan treatment attenuated the upregulation of $TNF-{\alpha}$, interleukin $(IL)-1{\beta}$, and IL-6 in ischemic kidneys. Fewer TUNEL positive cells were observed in IR-F10 compared to control mice. Fimasartan caused a significant decrease in caspase-3 activity and the level of Bax, and increased the Bcl-2 level. Fimasartan preserved renal function and tubular architecture from IRI in a mouse ischemic renal injury model. Fimasartan also attenuated upregulation of inflammatory cytokines and decreased apoptosis of renal tubular cells. Our results suggest that fimasartan inhibited the process of tubular injury by preventing apoptosis induced by the inflammatory pathway.

  • A mouse with cataract, Kec, was generated from N-ethyl-N-nitrosourea (ENU) mutagenesis. Cataract in the Kec mouse was observable at about 5 weeks after birth and this gradually progressed to become completely opaque by 12 weeks. Dissection microscopy revealed that vacuoles with a radial or irregular shape were located primarily in the cortex of the posterior and equatorial regions of the lens. At the late stage, the lens structure was distorted, but not ruptured. This cataract phenotype was inherited in an autosomal recessive manner. We performed a genetic linkage analysis using 133 mutant and 67 normal mice produced by mating Kec mutant (BALB/c) and F1 (C57BL/6 $\times$ Kec) mice. The Kec locus was mapped to the 3 cM region encompassed by D14Mit34 and D14Mit69. In addition we excluded coding sequences of 9 genes including Rcbtb2, P2ry5, Itm2b, Med4, Nudt15, Esd, Lcp1, Slc25a30, and 2810032E02Rik as the candidate gene that causes cataract in the Kec mouse.

  • The red pepper (Capsicum annuum L.) is one of the most important vegetables in traditional Korean food, containing vitamins A, C, and E, polyphenol, and flavonoids. In addition, red peppers have high anti-oxidant ability and are known to be effective in preventing obesity, diabetes, hypertension, digestive disorders, stress, and aging. In this study, we investigated the effects against obesity and diabetes of both fermented and non-fermented red pepper. C57BL/6N mice with induced obesity from an eight-week 45% high fat diet (HFD) were then fed either an HFD or diets containing 2.5% non-fermented red pepper marc (NRM), 1.25% fermented red pepper marc (FRM), or 2.5% FRM for a further eight weeks. An oral glucose tolerance test was performed seven weeks after dietary intake, and body weight, liver, epididymal fat weight, serum insulin level, and HOMA-IR were measured and a lipid content test performed at eight weeks. The results show that the 2.5% FRM diet reduced body and tissue weight, lipid content, serum insulin levels, and HOMA-IR compared to the 2.5% NRM and HFD diets. These results suggest that fermented red pepper is effective against obesity and diabetes. We will use this information as the basic data for the development of health food materials using red pepper.

  • Cells that have endogenous multipotent properties can be used as a starting source for the generation of induced pluripotent cells (iPSC). In addition, small molecules associated with epigenetic reprogramming are also widely used to enhance the multi- or pluripotency of such cells. Skinderived precursor cells (SKPs) are multipotent, sphereforming and embryonic neural crest-related precursor cells. These cells can be isolated from a juvenile or adult mammalian dermis. SKPs are also an efficient starting cell source for reprogramming and the generation of iPSCs because of the high expression levels of Sox2 and Klf4 in these cells as well as their endogenous multipotency. In this study, valproic acid (VPA), a histone deacetylase (HDAC) inhibitor, was tested in the generation of iPSCs as a potential enhancer of the reprogramming potential of SKPs. SKPs were isolated from the back skins of 5-6 week old C57BL/6 X DBA/2 F1 mice. After passage 3, the SKPs was treated with 2 mM of VPA and the quantitative real time RT-PCR was performed to quantify the expression of Oct4 and Klf4 (pluripotency specific genes), and Snai2 and Ngfr (neural crest specific genes). The results show that Oct4 and Klf4 expression was decreased by VPA treatment. However, there were no significant changes in neural crest specific gene expression following VPA treatment. Hence, although VPA is one of the most potent of the HDAC inhibitors, it does not enhance the reprogramming of multipotent skin precursor cells in mice.

  • Src family kinases (SFKs), an important group of non-receptor tyrosine kinases, are suggested to be excessively activated during various types of tissue fibrosis. The present study investigated the effect of KF-1607, an orally active and a newly synthesized Src kinase inhibitor (SKI) with proposed low toxicity, in preventing the progression of renal interstitial fibrosis. Unilateral ureteral obstruction (UUO) surgery was performed in 6-week-old male C57BL/6 mice to induce renal interstitial fibrosis. Either KF-1607 (30 mg/kg, oral gavage) or PP2 (2 mg/kg, intraperitoneal injection), a common experimental SKI, was administered to mice for seven days, started one day prior to surgery. UUO injury-induced SFK expression, including Src, Fyn, and Lyn kinase. SFK inhibition by KF-1607 prevented the progression of tubular injury in UUO mice, as indicated by decreases in albuminuria, urinary KIM-1 excretion, and kidney NGAL protein expression. Renal tubulointerstitial fibrosis was attenuated in response to KF-1607, as shown by decreases in α-SMA, collagen I and IV protein expression, along with reduced Masson's trichrome and collagen-I staining in kidneys. KF-1607 also inhibited inflammation in the UUO kidney, as exhibited by reductions in F4/80 positive-staining and protein expression of p-NFκB and ICAM. Importantly, the observed effects of KF-1607 were similar to those of PP2. A new pan Src kinase inhibitor, KF-1607, is a potential pharmaceutical agent to prevent the progression of renal interstitial fibrosis.

  • Objectives : The purpose of this study is analyzing the current research methodology of pharmacopucture for the treatment of animal cancer models. Methods : Four electronic databases were searched for animal studies published from January 2000 to September 2014 onward using these search terms "cancer, anticancer, pharmacopuncture, beevenom". Selected articles were described about animal cancer models. The methods used to induce cancer and the outcome measures used to assess the effects of pharmacopuncture on animal cancer models were analyzed. Results : 37 articles were included. For producing animal cancer models BALB/C mice(n=22) and C57BL/6 mice(n=17) were selected. And intravenous injection of B16-F10 melanoma cells into tail vein(n=14) or intraperitoneal injection of sarcoma-180 cells(n=14) were frequently used to induce cancer. Various pharmacopunctures were injected into acupoints $CV_{12}(n=19)$, $ST_{36}(n=8)$, $BL_{18}(n=8)$ or peritoneal cavity(n=6), tumor site(n=2), tail vein(n=2). Outcome measures were categorized into anti-cancer, anti-metastasis, general condition, cytotoxicity, immune response, toxicity. Median Survival Time(MST) and increase of life span(ILS)(n=26) was frequently used for evaluating anti-cancer effects. And pulmonary colonization assay(n=13) was frequently used for evaluating anti-metastasis effects Conclusions : Based on these data, further research would be needed to ascertain the effectiveness of pharmacopuncture for treating cancer and broaden the range of clinical applications.
