Clostridium perfringens causes diarrhea and other diseases in animals and humans. We investigated the prevalence, toxin gene profiles, and antibiotic resistance of C. perfringens isolated from diarrheic dogs (DD) and non-diarrheic dogs (ND) in two animal hospitals in Seoul, Korea. Fecal samples were collected from clinically DD (n = 49) and ND (n = 34). C. perfringens was isolated from 31 of 49 DD (63.3%) and 21 of 34 ND dogs (61.8%). All C. perfringens strains were positive for the ... -

This experimental controlled study was performed to evaluate the composition of autologous processed plasma (APP), and the effects of APP intra-articular injection into healthy equine metacarpophalangeal joints. The effects on joints were analysed with a short-phase protocol and a prolonged-phase protocol using saline-injected joints as controls. For the short protocol, horses received one intra-articular APP injection. Synovial fluid samples were collected prior to... -

parameters including the plaque index, gingival index, clinical attachment level, and bleeding on probing were significantly exacerbated in the SWL group compared to the other groups (p ＜ 0.05). Radiographic evaluation demonstrated that alveolar bone levels were significantly lower in the SWL group than the other groups on day 60 (p ＜ 0.05). These results suggested that experimental periodontitis induced by SWL could be an effective method for investigating periodontitis in canine models. -

2 isolates comprised 38.6% and 36.4% of total isolates, respectively, which were distributed in more than four provinces. SE and SE-like toxin genes were detected in 34 (77.3%) isolates and the most frequently detected SE gene profile was seg, sei, selm, seln, and selo genes (16 isolates, 36.3%), which was comparable to one of the genomic islands, Type I nSab. This is a first report of spa types and the prevalence of the recently described SE and SE-like toxin genes among S. aureus isolates from... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2017, Vol.21 No.3 10 353-360 (8 pages)
Several human diseases have been associated with mitochondrial voltage-dependent anion channel-1 (VDAC1) due to its role in calcium ion transportation and apoptosis. Recent studies suggest that VDAC1 may interact with endothelium-dependent nitric oxide synthase (eNOS). Decreased VDAC1 expression may limit the physical interaction between VDAC1 and eNOS and thus impair nitric oxide production, leading to cardiovascular diseases, including pulmonary arterial hypertension (PAH). In this report, we... -

This study was to determine the correlation between endothelial function and neuro-endocrine- immune (NEI) network through observing the changes of NEI network under the different endothelial dysfunction models. Three endothelial dysfunction models were established in male Wistar rats after exposure to homocysteine (Hcy), high fat diet (HFD) and Hcy+HFD. The results showed that there was endothelial dysfunction in all three models with varying degrees. However, the expression of NEI network was... -
Gene Expression Profile in Microglia following Ischemia- Reperfusion Injury
JuHyeonOh, HyungSooHan, JaeSikPark 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 8 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2006, Vol.10 No.4 2 173-180 (8 pages)
Microglial activation is thought to play a role in the pathogenesis of many brain disorders. Therefore, understanding the response of microglia to noxious stimuli may provide insights into their role in disorders such as stroke and neurodegeneration. Many genes involved in this response have been identified individually, but not systematically. In this regards, the microarray system permitted to screen a large number of genes in biological or pathological processes. Therefore, we used microarray... -

a simple method to predict the neuronal cell death in the mouse hippocampus and striatum following transient global forebrain ischemia by evaluating both cerebral blood flow and the plasticity of the posterior communicating artery (PcomA). Male C57BL/6 mice were anesthetized with halothane and subjected to bilateral occlusion of the common carotid artery (BCCAO) for 30 min. The regional cerebral blood flow (rCBF) was measured by laser Doppler flowmetry. The plasticity of PcomA was visualized by... -
Genetic Reassortment of Rice stripe virus RNA Segments Detected by RT-PCR Restriction Enzyme Analysis-based Method
한국식물병리학회 The Plant Pathology Journal 8 Pages

reverse transcription- polymerase reaction/restriction enzyme (RTPCR/ RE) analysis-based method. We identified five REs, including DraI, EcoR1, NdeI/AseI, and SpeI, that could differentiate RSV RNA 1-4 subtypes, respectively. Our RT-PCR/RE results provided a clear pattern of RNA reassortment, i.e., different groups of isolates having their RNA segments derived from two to three different RSV ancestors, such as from Eastern and Southwestern Chinese or Japanese M and T isolates. We also found that... -

한국교육학회 교육학연구 2021, 59권 3호 3 55-90 (36 pages)
The purpose of this study was to develop a theory of students’ transition to college and to confirm that theory. To understand the nature and meaning of the first-year transition, a qualitative study was conducted using grounded theory, and a questionnaire was developed based on the established transition theory. The validation of the theory was analyzed through structural equation modeling (SEM), and a multi-group analysis was conducted to find out what differences existed in the structural... -

wide variety of genetic applications and is an efficient method for detection of mutations involving one or a few nucleotides. We developed a high-throughput DHPLC method for identifying polymorphisms in the MC1R gene that are characteristic of Hanwoo cattle. We compared 10 tissue samples from Hanwoo cattle, 10 samples from Holstein cattle and 10 samples from Hanwoox Holstein crossbred cattle to determine whether DHPLC analysis can be used to distinguish between these genotypes. Samples obtained... -
