Aims: The number of elderly patients diagnosed with hepatocellular carcinoma (HCC) has been increasing because the increase in the longevity of the general population. But there is no proper management based on age stratification in elderly patients. We compared clinical characteristics, outcomes and treatment efficacy, safety between oldest-old (aged more than 85 years), middle-old (aged between 80 and 85 years) and young-old (aged between 75 and 80 years) patients with HCC. Methods: We conducted a retrospective cohort study, from January 2010 to December 2016, at Chonnam National University Hospital. A total of 550 elderly patients whose data included demographics, co-morbidity, etiology of liver disease, presence of cirrhosis, staging of HCC, treatment modality and treatment related adverse event were evaluated retrospectively. Also overall survival was assessed in enrolled patient. Results: Fifty one patients (oldest-old; median 87 years old), 153 patients (middle-old; median 82 years old) and 346 patients (young-old; median 77 years old) were diagnosed with HCC. Both oldest- and middle-old patients, compared to young-old patients had significantly lower rate of alcohol-related disease (13.7% vs 20.9% vs 34.1%, P = 0.001). There were no significant difference in underlying sex, body mass index, presence of co-morbidity, hepatitis C-related disease and stage of HCC. The Child-Pugh class (CPT class A 88.9% vs 84.1% vs 83.6%, CPT class B 11.1% vs 15.9% vs 15.0% and CPT class C 0.0% vs 0.0% vs 1.3%, respectively, P = 0.912) and Model for End Stage Liver Disease score (mean MELD score 7.22±3.34 vs 5.88±3.01 vs 5.77±3.14, P = 0.166) were no significant difference between the patients with active treatment. The modified UICC staging (stage I 5.6% vs 17.1% vs 18.6%, stage II 55.6% vs 46.3% vs 47.3%, Stage III 22.2% vs 24.4% vs 24.8%, Stage IV-A 11.1% vs 6.1% vs 4.9% and Stage IV-B 5.6% vs 6.1% vs 4.4%, respectively, P = 0.826) and Barcelona Clinic Liver Cancer staging (stage 0 5.6% vs 9.8% vs 9.3%, stage A 16.7% vs 17.1% vs 22.1%, stage B 27.8% vs 29.3% vs 24.8%, stage C 50.0% vs 43.9% vs 41.2% and stage D 0.0% vs 0.0% vs 2.7%, respectively, P = 0.878) were no significant difference between the patients with active treatment. Furthermore, there were no difference between the age groups in treatment modality (Surgical resection 0.0% vs 3.3% vs 5.2%, P = 0.166; Radiofrequency ablation 2.0% vs 8.5% vs 11.0%, P=0.113; Transcatheter arterial chemoembolization 21.6% vs 34.6% vs 41.6%, P=0.014; Best supportive care 62.7% vs 40.5% vs 29.2%, P < 0.001), adverse event related treatment (P = 0.731) and disease-free survival days (329 .3±309.1 days vs 271.7 ± 414.2 days vs 357.2 ± 511.6 days, P = 0.336). Multivariate analysis showed that age, performance status, CTP class, MELD score, modified UICC staging, presence of portal vein thrombosis and ruptured HCC are risk factors for mortality. Conclusions: Clinician should make an active treatment in elderly patients with HCC not a age but performance status, liver function and disease status of cancer.

Steroid cell tumor is a rare ovarian sex cord-stromal tumor which accounts for 0.1% of all ovarian tumors. Until now, only 4 cases have been reported in domestic literatures. Steroid cell tumor often secrets testosterone and presents virilization in adult women or precocious puberty in children. Treatment is often performed by surgical removal, adjuvant chemotherapy and radiation, but completely accepted treatment was not existed. We experienced a case of steroid cell tumor, which was manifested by typical virilization in a 43-year old patient, who was previously performed hysterectomy and unilateral oophorectomy. So, we present with a brief review of the literatures.

Lee, Nam-Hun,Seo, Chang-Seob,Lee, Ho-young,Jung, Da-Young,Lee, Jun-Kyung,Lee, Jin-Ah,Song, Kye Yong,Shin, Hyeun-kyoo,Lee, Mee-Young,Seo, Young Bae,Kim, Hokyoung,Ha, Hyekyung Hindawi Publishing Corporation 2012 Evidence-based Complementary and Alternative Medic Vol.2012 No.-

<P>The fruit of <I>Cornus officinalis </I>Sieb. et Zucc. is commonly prescribed in Asian countries as a tonic formula. In this study, the hepatoprotective effect of ethanolic extracts of the fruit of <I>C. officinalis</I> (ECO) was investigated in a mouse model of acetaminophen- (APAP-) induced liver injury. Pretreatment of mice with ECO (100, 250, and 500 mg/kg for 7 days) significantly prevented the APAP (200 mg/kg) induced hepatic damage as indicated by the serum marker enzymes (AST, ALT, and LDH). Parallel to these changes, ECO treatment also prevented APAP-induced oxidative stress in the mice liver by inhibiting lipid peroxidation (MDA) and restoring the levels of antioxidant enzymes (SOD, CAT, and HO-1) and glutathione. Liver injury and collagen accumulation were assessed using histological studies by hematoxylin and eosin staining. Our results indicate that ECO can prevent hepatic injuries associated with APAP-induced hepatotoxicity by preventing or alleviating oxidative stress.</P>

<P><B>Abstract</B></P> <P>Inflammatory bowel disease (IBD) is chronic inflammation of the gastrointestinal tract caused by high levels of pro-inflammatory cytokines and epithelial barrier dysfunction. <I>Alnus japonica</I> Steud. (Betulaceae) has been used in traditional Asian medicine. However, the potential of <I>A. japonica</I> for the treatment of intestinal inflammation has not been investigated. This study investigated the effects of ethanol extract from <I>A. japonica</I> bark (AJE) on colonic mucosa injury in mice with dextran sodium sulfate (DSS)-induced colitis. Treatment with AJE ameliorated pathological damage and the histopathologic features of DSS-induced colitis. The administration of AJE also inhibits DSS-induced pro-inflammatory cytokines expression, including interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and cyclooxygenase (COX)-2. Notably, AJE administration attenuated the reduction of tight junction proteins, zonula occludens (ZO)-1 and occludin, in DSS-induced colitis. In addition, AJE increased heme oxygenase (HO)-1 expression and prevented DSS-induced apoptosis in colonic epithelial cells. Furthermore, <I>in vitro</I> studies demonstrated that AJE inhibits TNF-α-induced IL-8, IL-1β, and COX-2 expression in human intestinal epithelial HT-29 cells and <I>tert</I>-butyl hydroperoxide-induced reduction of ZO-1 and occludin expression in human intestinal epithelial Caco-2 cells. AJE-induced HO-1 protein expression was also found in both HT-29 and Caco-2 cells. Taken together, our findings demonstrated that AJE inhibits intestinal inflammation and protects against intestinal barrier disruption in mice with DSS-induced colitis <I>in vivo</I> and human intestinal epithelial cells <I>in vitro</I>. These results suggest that AJE might have beneficial effects for the treatment of IBD.</P> <P><B>Highlights</B></P> <P> <UL> <LI> AJE attenuates the severity of DSS-induced colitis mice. </LI> <LI> AJE suppresses expression of pro-inflammatory mediators in DSS-induced colitis mice. </LI> <LI> AJE protects intestinal barrier integrity in DSS-induced colitis mice. </LI> <LI> AJE increases HO-1 expression in mouse colonic epithelial cells. </LI> <LI> AJE inhibits inflammation and protects loss of TJ proteins of human IEC cells. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Xu, Zheng Run,Park, Hae Youn,Kim, Ho Young,Seo, Kwan Ho WILEY-VCH Verlag 2008 Macromolecular symposia Vol.264 No.1

<P>In this study, nanocomposites of poly(ethylene-co-vinyl acetate) with two kinds of organically modified montmorillonite (OMMT) were prepared by melt intercalation. Their structures and mechanical properties were characterized by X-ray diffraction (XRD) and tensile test respectively. Especially, foaming of these nanocomposites mixed with chemical blowing agent was carried out through compression molding. Influences of OMMT on foaming ratio and mechanical properties were investigated by density test, tensile test and tear test. Results revealed that both kinds of OMMT with proper content increased tensile strength and Young's modulus of nanocomposites without a compromise of elongation at break. For foaming, OMMTs apparently improved foaming ratio and in particular, one of them can improve tear strength, tensile strength, Young's modulus and elongation although the density was decreased.</P>

Antioxidant activity in vitro and mucosal protective effect of Rhei Rhizoma on reflux esophagitis induced in rats

Ah Reum Lee,Yu Ock Shin,Joo Young Lee,Min Yeong Kim,Sung Ho Shin,Bu-Il Seo,Young-Bae Seo,Man Hee Rhee,TakakoYokozawa,Chan Hum Park,Seong-SooRoh 한국약용작물학회 2015 한국약용작물학술대회 발표집 Vol.2015 No.05

Purpose Rhei Rhizoma (RR) is one of the herbal medicines traditionally used to treat diverse inflammatory diseases. The present study was undertaken to elucidate the antioxidant and anti-inflammatory activities of Rhei Rhizoma on experimental reflux esophagitis (RE) in rats. Methods The antioxidant activity of RR in vitro was measured in terms of radical scavenging capacity such as DPPH and ABTS. RE was produced by ligating both the pylorus and the transitional junction between the forestomach and the corpus. Rhei Rhizoma (125 and 250 mg/kg) were administered every day for 7 days, and its effect was estimated on comparison with RE control and normal rats. Results RR scavenged DPPH and ABTS effectively and IC50ofDPPH and ABTS radical scavenging activity of RR were 4.8 μg/ml and 15.75 μg/ml. The administration of RR decreased the elevated serum ROS in RE control rats. The RE control rats exhibited the down-regulation of antioxidant-related proteins such as Nrf2 and HO-1expression levels in the esophagitis; however, the level in the RR-treated RE rats was significantly higher than that in the RE control rats. Moreover, RE control rats exhibited the up-regulation of the protein expression related to oxidative stress at the esophagitis, but RR administration significantly reduced the expression of inflammatory proteins through the MAPK-independent signaling pathways. The expression of inflammatory mediators and cytokines by NF-κB activation was modulated through blocking the degradation of IκBα. In addition, the oral administration of RR regulated the gastric mucosal damage in RE rats. Conclusion The administration of Rhei Rhizoma effectively ameliorates the inflammatory damage of esophageal mucosa through radical scavenging activity and the activation of the Nrf2/HO-1 pathway.

So Hee Ahn,Won Yeoung Choi,Ji Won Jeong,Geon Woo Park,Su Yeon Kang,Eun Jeong Kim,Su Rim Sin,Eun Seo Jang,Gye Won Lee,Young Ho Cho 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

In this study, To investigate the antioxidant activities of Rhaponticum uniflorum extracts (RUE), we assessed scavenging activities on DPPH, ABTS radicals, and reducing power. The DPPH and ABTS radical scavenging activities (SC50) of RUE were 96.97±1.19 μg/mL and 31.26±0.13 μ g/mL, respectively, and the reducing power significantly increased dose-dependent manner. To study the antioxidant effecters of RUE in H₂O₂ induced human keratinocytes, expression of Nuclear factor erythroid-2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) were determined by Western blot and qRT-PCR. RUE induced the expression of HO-1, a critical target enzyme of Nrf2, in a concentration-dependent manner. The expression of HO- 1 mRNA was also induced in H₂O₂-treated HaCaT cells but no significant difference in the level of HO-1 mRNA was observed. Taken together, these results suggest that RUE may be useful as a potential ingredient for anti-aging products.

This paper was undertaken to do morphological analysis of wear debris on no additive and additive lubricating oil. The lubricating wear test was performed under different experimental conditions using the wear test device was made in our laboratory and wear specimens of the pin on disk type was rubbed in paraffine series base oil by materials, varying applied load, sliding distance, oil additives such as stearine acid, DBDS, TCP. Morphologic character of wear debris is easily distinguished by four shape parameter(50% volumetric diameter, aspect, roundness and reflectivity). As the applied load sliding distance increase, size and shape of wear debris was complexed, but reflectivity was decreased, a large wear debris was apt to be oxidezed.

Maize hybrids were planted on April 1, April 25, May 20 and June 15 in 2012, 2013 at the experimental paddy and upland fields in Suwon city , respectively to know changes of growth stage and yield according to different planting time. Maize planting on April 1 was not recommended because total growing days at planting on April 1 was not different with that at planting on April 25 due to many days from planting to emergence over 20 days at planting on April 1. Total growing days were not much different among three planting time after April 25 because days from silking to maturity was lengthened though days from planting to silking was shortened at later planting time. Stalk weight was decreased as planting time was delayed, particularly at planting times after May 20 at paddy field by excess water injury during early growth stage. But, grain yield was not low as in May and June. It is needed to introduce early maturity maize variety as Yanganok at late planting for higher grain yield and enough time for soil preparation for next winter crops
