<P><B>Objectives</B></P><P>Poststroke emotional incontinence (PSEI) has been associated with serotonergic dysfunction. Polymorphisms of serotonin transporter (5‐HTT) and serotonin 2a receptor (5‐HTR2a) genes may regulate serotonergic signaling at brain synapses, and this study was to investigate associations with PSEI in an East Asian population.</P><P><B>Methods</B></P><P>In 276 stroke cases, PSEI was diagnosed by Kim's criteria. Covariates included age, gender, education, history of depression or stroke, current depression, and stroke severity and location. Genotypes were ascertained for 5‐HTT gene‐linked promoter region (5‐HTTLPR), serotonin transporter intron 2 variable number tandem repeat, 5‐HTR2a 1438A/G, and 5‐HTR2a 102 T/C.

Background Excessive intake of fat, one of the causes of obesity, is associated with low-grade infammation in various susceptible organs and eventually causes tissue toxicity. This study examines the multifaceted suppressive efects of Korean red ginseng extract (KRG) on high-fat diet (HFD)-induced lipotoxicity and infammatory responses in the aorta, liver, and brain. Methods Male C57BL/6 mice were fed HFD with or without KRG for 12 weeks. The improvement efect in KRG on lipotoxicity and infammatory potential was determined in the blood and the aorta, liver, and brain tissues. Results KRG signifcantly inhibited 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase activity by >20% in vitro. KRG supplementation suppressed HFD-associated body weight gain, lipid profle changes, and excessive fat deposition in the liver and increased leptin, insulin, and ALT levels in the blood. Infammatory markers in the aorta, liver, and brain were also signifcantly reduced by KRG treatment. In microvascular endothelial cells, the 15% cyclic stretch-mediated upregulation of ICAM-1 and vascular cell adhesion protein-1 (VCAM-1) expression was signifcantly attenuated in the presence of KRG. Conclusion KRG supplementation attenuates HFD-mediated body weight gain, lipid profle changes, and multi-tissue infammatory responses.

The present study investigated the habitats of Korean fir trees (Abies koreana E. H. Wilson) on Mt. Baekwun (Baekwun-san), determined the current distribution, quantified the contribution of biological and nonbiological environmental factors affecting the distribution, derived actual and potential habitats, presented a plan for the establishment of protected areas, applied RCP 8.5 climate change scenario to analyze the effects of climate change on the future distribution of Korean fir trees, and predicted future potential habitats. According to the results of the study, 3,325 Korean fir trees (DBH >= 2.5 cm) inhabited Mt. Baekwun, and their distribution area was approximately 150 ha. Populations of Korean fir trees were confirmed to exist at an altitude of 900 m above sea level and were distributed up to 1,200 m. Based on potential distribution, areas appropriate for habitation by Korean fir trees were analyzed to be 450 ha, three times the current distribution area, with a focus on Sang Peak (Sang-bong), Eokbul Peak (Eokbul-bong), Ddari Peak (Ddari-bong), and Dosol Peak (Dosol-bong). The forest stands near Sang Peak, the main peak, were evaluated as those with the most appropriate potential for the habitation of Korean fir trees, and populations of the trees tended to prefer the northern slope rather than the southern slope. When climate change scenario RCP 8.5 was applied and future potential distribution was analyzed, the habitats were expected to decrease in area to 20 ha by 2050, with a focus on Sang Peak, and areas appropriate for habitation were predicted not to exist by 2080. Judging from such results, as global warming accelerates, the habitats of Korean fir trees are clearly expected to move from lowlands to highlands.

Background: Ischemia-reperfusion injury (IRI) is a leading cause of acute kidney injury with high morbidity and mortality due to limited therapy. AKI emerges in various clinical settings and is complex with outcome linking oxidative stress, inflammation, and cell death. Therefore protection of AKI is still an unsolved problem. Indomethacin is generally known that it inhibits the production of prostaglandins through the inhibition both cyclooxygenase (COX) 1 and 2. Prostaglandins have a wide variety of effect such as regulation of vasodilation, inflammation, regeneration, pain, fever. Therefore effect of indomethacin in AKI is different according to injury model. We investigated whether indomethacin which inhibits the production of prostaglandins aggravate the renal injury in AKI mouse model. Methods: Male C57/BL6 mice (8-10 weeks old, weight 20~25 g) were used. Acute kidney injury is induced by bilateral kidneys pedicle clamping which were subjected to 20 min or 30 min at both kidneys. Mice were treated with indomethacin at before and after injury. Blood and kidney samples were collected at 24 hr after IRI. The expression level of creatinine, N-gal & Kim-1 were detected in serum. And the expression level of PGE2, cAMP and adenosine were detected in kidney. Kidney Injury score were measured by HE staining and TUNEL. Results: In bilateral AKI model, Serum NGAL level and creatinine level were significantly highest in indomethacin treated group compared to non-treated group (NGAL, p<0.05; creatinine, p<0.01). Indomethacin treated group showed significantly more necrosis and apoptosis compared to non-treated group. Furthermore, Indomethacine inhibited the production of prostaglandins, cAMP and adenosine. Conclusions: Indomethacin inhibits adenosine-mediated renal protection by inhibition of prostaglandin production in AKI. Therefore Indomethacin worsened renal injury by inhibition of prostaglandin production in AKI. * This research was supported by a grant of the Korea Health Technology R&D Project through the KHIDI, funded by the Ministry of Health & Welfare, Republic of Korea (grant number :H15C2212)

The aim of this study was to isolate microorganisms from half milk samples of dairy goats by California mastitis test (CMT) during the lactation period and to further investigate the susceptibility of isolated organisms to antimicrobial drugs. From a total of 235 half milk samples with CMT scores of 2 or above from 366 dairy goats distributed throughout Jeonnam province, microorganisms were isolated from 198 (83.5%) samples either singly (99.0%) or in combination (1.0%). The most prevalent microorganism was the coagulase-negative Staphylococcus spp., (44.4%, n=88) followed by Staphylococcus aureus (24.2%, n=48), Escherichia coli (11.1%, n=22) and Streptococcus spp. (7.6%, n=15). Isolated bacteria also included Bacillus spp. (2.5%, n=5), Pseudomonas spp. (2.5%, n=5), Micrococcus spp. (1.5%, n=3), Corynebacterium spp. (1.5%, n=3), Enterococcus facium (1.0%, n=2), Morganella morganii (0.5%, n=1) and Streptococcus agalactiae (0.5%, n=1). During the summer season, a high prevalence of all micro-organisms were observed in which Staphylococcus spp. (30.8%), Escherichia coli (8.6%), and Streptococcus spp. (5.6%) were among the most prevalent bacteria isolated. Staphylococcus spp. was also shown to be high in the winter (21.7%). In most samples, the presence of bacterial pathogens in goat milk led to the increase in the total somatic cell count (SCC). Most of the half milk samples of dairy goats with bacterial contamination showed SCC of ≥1×10(6) cells/ml (90.4%). Minor pathogens (11.4%) were more detected from milk samples with SCC of <1×10(6) cells/ml than major pathogens (4.1%), while the major pathogens tended to be higher from samples with SCC of ≥3×10(6) cells/ml. Susceptibility of these bacteria to 12 antimicrobial agents was tested by the Kirby-Bauer disc diffusion method. Results indicated that more than 90% of bacteria isolated from CMT 2+ dairy goat half milk samples were susceptible to trimethoprim/sulfamethoxazole, amoxicillin/clavulanic, enrofloxacin and cephalothin while they were resistant to tetracycline (44.7%).
