Objectives : This study was designed to investigate anti-obesity effects of DF in a ob/ob mouse model. Methods : Fifteen-week-old ob/ob mice were divided into four groups: a normal lean group given a standard diet, an ob/ob control group given a standard diet, and DF(1) and DF(2) groups given a standard diet with DF(1) (300 mg/kg), and DF(2) (600 mg/kg), respectively. After 10 weeks of treatment, body weight gain, feeding efficiency ratio, blood lipid markers, fat weight and histology were examined. Results : Body weight gain and fat mass were significantly decreased in DF(1) and DF(2) groups compared with control. The extent of decreases was eminent in DF(2) group. Feeding efficiency ratio were significantly decreased in DF(2) group compared with control. Consistent with their effects on body weight gain and fat mass, circulating concentrations of LDL, total cholesterol, free fatty acid, and insulin were decreased in DF(2) group compared with control. The size of adipocytes were significantly decreased by DF(2) compared with control. Consistent with their effects on body weight gain, hepatic lipid accumulation and liver weights were reduced in DF compared with control. Conclusions : In conclusion, these results suggest that DF not only decrease feeding efficiency ratio, and blood anti-obesity biomarkers, but also reduce fat mass, contributing to the improvement of obesity. DF also inhibits hepatic lipid accumulation.

Combinations of multiple biomarkers representing distinct aspects of metastasis may have better prognostic value for breast cancer patients, especially those in late stages. In this study, we evaluated the protein levels of N-${\alpha}$-acetyltransferase 10 protein (Naa10p), synuclein-${\gamma}$ (SNCG), and phosphatase of regenerating liver-3 (PRL-3) in 365 patients with breast cancer by immunohistochemistry. Distinct prognostic subgroups of breast cancer were identified by combination of the three biomarkers. The Naa10p+SNCG-PRL-3-subgroup showed best prognosis with a median distant metastasis-free survival (DMFS) of 140 months, while the Naa10p-SNCG+PRL-3+subgroup had the worst prognosis with a median DMFS of 60.5 months. Multivariate analysis indicated Naa10p, SNCG, PRL-3, and the TNM classification were all independent prognostic factors for both DMFS and overall survival (OS). The three biomarker combination of Naa10p, SNCG and PRL-3 performed better in patients with lymph node metastasis, especially those with more advanced tumors than other subgroups. In conclusion, the combined expression profile of Naa10p, SNCG and PRL-3, alone or in combination with the TNM classification system, may provide a precise estimate of prognosis of breast cancer patients.

Reactive humsn mesothelial cells were examined by immunocytochemical stain with intermediate filaments (cytokeratin [CK1, CK7, CK8, CK18, CD19), vimentin, desmin, actin), epithelial membrane antigen, carcinoembryonic antigen (CEA), MHC class II antigen (HLA-DR), LeuM-1 (CD15), $\alpha1-antitrypsin$(ACT), $\alpha1-antichymotrypsin$ (ACHT), CD68(KP-1) and FcyRIII(CD16). The mesothelial cells were isolated from patients with liver cirrhosis and pleural effusion, and short-term cultured in RPMI 1640 media containing 10% heat inactivated fetal calf serum and 1% identical supernatant fluid of the patients' transudates. The results obtained are as follows 1. The cultured-reactive mesothelial cells were positive for the protein of cytoskeleton such as cytokeratin and vimentin, but negative for desmin and actin. The resting mesothelial cells showed positive reactions for cylokeratin, but negative for vimentin, desmin and actin. 2. The primary antibodies to the cytokeratin were strongly reactive for CK1, CK8 and CK18 but negative for CK7 and CK19 in both reactive and resting mesothelial cells. 3. Resting mesothelial cells showed negative reactions for CEA, but strong positive reactions in cultured-reactive mesothelial cells. 4. The markers for the monocytes/histiocytes(CD11b, CD14, CD16, CD68, Iysozyme and $\alpha1-antitrypsin$ and $\alpha1-antichymotrypsin$) were nonreactive in resting mesothelial cells, but lysozyme and $\alpha1-antitrypsin$ were weakly reactive in reactive and proliferative mesothelial cells. 5. MHC Class II molecule(HLA-DR antigen) was negative in both resting and reactive mesothelial cells. These results suggest that the short-term cultured, reactive mesothelial cells show a newly aberrant expression of the vimentin and calcine-embryonic antigen. The reason of the aberrant expression of the intermediate filament and oncofetal antigen in reactive and proliferative mesothelial cells should be further evaluated.

국내 정부 지원 무료 검사로 진행 중인 6종 신생아 선별 검사에서 호모시스틴뇨증을 진단하기 위해 메티오닌의 증가가 마커로 사용되고 있다. 그러나 실제 고메티오닌혈증에서 감별해야 하는 질환들에는 간질환, tyrosinemia type I (MIM #276700), methionine adenosyltransferase (MAT) I/III 결핍, glycine N-methyltransferase (GNMT) 결핍, adenosylhomocy-steine hydrolase (SAHH) 결핍, adenosine kinase (ADK) 결핍, citrin deficiency (citrullinemia type I) 등이 있다. 고메티오닌혈증의 흔한 원인이자 양성 질환으로 알려졌던 MAT I/III 결핍 질환은 유전 방식에 따라 신경학적 증상 발현 및 치료의 필요성이 보고되고 있어 신생아 선별검사에서 고메티오닌혈증 양성으로 나올 경우 감별 진단 및 처치에 대한 가이드라인이 필요하겠다. 신생아 선별검사에서 고메티오닌혈증 양성으로 나올 경우, 간수치 및 혈장 아미노산 분석, 혈장 총 호모시스테인 수치를 통해 여러 질환 들을 감별할 수 있으며 혈장 총 호모시스테인의 증가가 40 umol/L 미만의 경우에서는 MAT I/III 결핍을 먼저 고려해 볼 수 있겠다. MAT I/III 결핍에서는 우성 유전형일 경우에는 치료가 필요 없지만 열성 유전형에서는 정기적인 발달 지표, 혈장 메티오닌과 총 호모시스테인 수치의 추적이 필요하겠으며 심한 고메티오인혈증(>800umol/L)에서는 저메티오닌식이를, 발달 지연, 뇌말이집 형성 장애가 동반한 경우에는 S-adenosylmethio-nine (SAM) 복용을 고려한다. 호모시스틴뇨증에서는 절반에서 피리독신 반응형을 보이고 피리독신 반응형은 조기에 메티오닌 증가가 없을 수 있기에 선별검사에서 놓칠 수 있다. 치료에는 저메티오닌 식이, 피리독신, 베타인, 엽산 등이 있으며 베타인 투약시 메티오닌 증가로 인한 뇌부종에 대한 주의가 필요하다. 그 외 GNMT, SAHH, ADK 결핍은 현재 환자 수와 예후가 제한적으로 조기 진단 및 치료에 대한 뚜렷한 이득이 명확하지 않은 상태이다. 미국, 유럽의 일부 기관들에서는 낮은 메티오닌 수치로 재메칠화 장애에 대한 선별검사도 시행하고 있어 국내에도 관련 질환에 대한 현황 및 선별검사 도입의 필요성에 대해 논의가 필요하겠다.

The retinoids (vitamin A and its derivatives) play a critical role in vision, growth, reproduction, cell differentiation and embryonic development. Using the IMpRH panel, porcine cellular retinol binding protein genes 5 and 7 (RBP5 and RBP7) were assigned to porcine chromosomes 5 and 6, respectively. The complete coding sequences (CDS) of the RBP5 and RBP7 genes were amplified using the reverse transcriptase polymerase chain reaction (RT-PCR) method, and the deduced amino acid sequences of both genes were compared to human corresponding proteins. The mRNA distributions of the two genes in adult Wuzhishan pig tissues (lung, skeletal muscle, spleen, heart, stomach, large intestine, lymph node, small intestine, liver, brain, kidney and fat) were examined. A total of nine single nucleotide polymorphisms (SNPs) were identified in two genes. Three of these SNPs were analyzed using the polymerase chain reaction-restriction-fragment length polymorphism (PCR-RFLP) method in Laiwu, Wuzhishan, Guizhou, Bama, Tongcheng, Yorkshire and Landrace pig breeds. Association analysis of genotypes of these SNP loci with economic traits was done in our experimental populations. Significant associations of different genotypes of $RBP5-A/G^{63}$, $RBP5-A/G^{517}$ and $RPB5-T/C^{intron1-90}$ loci with traits including maximum carcass length (LM), minimum carcass length (LN), marbling score (MS), back fat thickness at shoulder (SBF), meat color score (MCS) and hematocrit (HCT) were detected. These SNPs may be useful as genetic markers in genetic improvement for porcine production.

Hematological and serum biochemical analyses are routinely used to screen dogs for disease and monitor their clinical progression. These values in dogs may be affected by internal factors, such as breed and age, and external factors like environment, diet, and lifestyle. Apparently, subclinical breed-related variations in hematologic and serum biochemical results have been characterized for Bernese Mountain dogs, Alaskan Malamutes, English Setters, and Golden Retrievers. It is possible that some breed-related differences in clinical pathology analyses may reflect evidence of underlying disease and impact clinical decision plan. In this study, we estimated hematologic and serum biochemical parameters in small breed dogs and compared among four different breed dogs. Blood samples were collected from 38 domestic dogs that were 10 Beagles, 9 Malteses, 10 Poodles, and 9 Miniature Schnauzers. In terms of RBC count, Beagle ($7.2{\pm}0.24{\times}10^3cells/{\mu}L$) showed significantly (P<0.05) higher count than other breeds (Maltese, $6.51{\pm}0.25{\times}10^3cells/{\mu}L$; Poodle, $6.35{\pm}0.24{\times}10^3cells/{\mu}L$; and Miniature Schnauzer, $6.35{\pm}0.25{\times}10^3cells/{\mu}L$). For MCV, Miniature Schnauzer ($67.05{\pm}0.84fl$) results were significantly (P<0.05) higher than Beagle with $64.33{\pm}0.8fl$. For cholesterol value, Beagle ($163.3{\pm}9.15mg/dl$) had significantly (P<0.05) higher values than Miniature Schnauzer with $119.12{\pm}9.64mg/dl$. There was no statistically difference among breeds in terms of enzyme markers of liver diseases. In conclusion, data obtained from this study may be valuable as breed-related variability for interpretation of the results in hematologic and serum biochemical analysis among four small breed dogs.

Objectives: There is a steady increase in the prevalence of obesity worldwide and obesity is often accompanied by inflammation. Although much emphasis has been placed on the adipose tissue inflammation in obesity, a study with herbal medicine is few. This study aimed to investigate the antidiabetic and anti-inflammatory effect of a complex herbal medicine (CHM) composed of Cornus officinalis, Dioscorea rhizoma, Aurantii fructus, and Mori Foliumon on obese type 2 diabetes mice. Methods: Type 2 diabetes mellitus and obesity were induced by Surwit's high fat, high sucrose diet for 8 weeks. Mice were divided into ND (normal diet, n=10), HFD (high fat and high sucrose diet, n=10), CHM (high fat and high sucrose diet with complex herbal medicine, n=10) and Met (high fat and high sucrose diet with metformin, n=10) groups. The body weight, fructosamine and OGTT (oral glucose tolerance test) were measured. After 8 weeks the blood samples of all mice were taken from the heart, and lipid profiles were measured. Epididymal fat pad, histological size of the adipocyte tissue and liver weights were measured. Inflammatory markers such as leptin and adipocyte tissue macrophage were measured to evaluate the effect of CHM on adipocyte tissue inflammation. Results: Compared with the HFD group, there was an improvement in OGTT and epididymal fat decreased in the CHM group. White adipocyte size and adipocyte tissue macrophage decreased in CHM group. Conclusions: These results suggest that CHM has antidiabetic and anti-inflammatory effects in high fat, high sucrose diet induced obese mice.
