The aim of this article is to clarify the origin of the Korean armed struggle in Chien tao and Russian Far East in the early 1920s. In conclusion, I believe that the origin of Korean armed struggle is the Russian Revolution in 1917 and ensuing civil war in Siberia. In particular, Japanese forces in Siberia after the Russian Revolution made Koreans in that region to struggle with Soviet Red Army and Russian partisan troops. Japan has sent troops to Siberia in 1918 and supported White army in Russian civil war. For this reason Koreans naturally jumped into the fight against the Japanese and the Whites. And the armed struggle taken place in Siberia soon had an impact on the Korean community in Chientao. Korean patriots in Chien tao also began a battle with the Japanese. From this wide range of armed struggle has unfolded in Chientao and Russian Far East in the early 1920s. But the Koreans partisan movement in Russia also had to be affected to the presence and movements of Koreans in that Region in the previous time. Korean community in Russia also had a class problem. Some of Koreans who early imigrated to the Russian territory and acquired Russian nationality, received land distribution from the Russian government and were incorporated into the ruling class. They were called 'Won-he-in'. In contrast, there were Koreans who were not acquired Russian nationality. As there was no land for them, They had cultivated the land of Russian landlord or Won-ho-in. otherwise, became the daily agricultural workers. They were "Yo-ho-in". And of course, Won-he-in were the side of White army and Red army had the support of Yo-ho-in.

The objective of this study was to determine the effect of macrophages on growth of human colon cancer cells. The results showed that co-culture of colon cancer cells with macrophages inhibited the growth of colon cancer cells (HCT116 and SW620) depending on the number of macrophages, RAW 264.7 cells, and activated THP-1 cells accompanied by down regulation of pSTAT3 in cancer cells. We also found that expression and release of cancer cell growth inhibitory cytokines, IL-1 receptor antagonist (IL-1ra) and IL-10, was increased in macrophages. Blocking of the STAT3 pathway with specific inhibitor and siRNA of STAT3 abolished the growth of colon cancer cells and expression of IL-1ra and IL-10. In addition, neutralization of IL-1ra and IL-10 with antibodies resulted in reversal of macrophage-induced inhibition of cancer cell growth. These data showed that IL-1ra and IL-10 released from macrophages inhibit growth of colon cancer cells through inhibition of the STAT3 pathway

Colonoscopic polypectomy is a commonly performed procedure in Korea, subsequently prevents colon cancer. The increase of therapeutic colonoscopy, polypectomy, results in inevitably various complications including bowel perforation that is rare and requires emergent decision of treatment modalities and timely treatment. The bowel perforation is usually diagnosed on the basis of pneumoperitoneum on simple X-ray images. Surgery is the treatment of choice for most cases of colonic perforation. A 58-year-old woman was referred to the gastroenterologist for endoscopic mucosal resection (EMR) of laterally spreading flat adenoma in the sigmoid colon. The EMR was performed with flexible and insulated tip knives. The patient was hospitalized for close observation of post-EMR complications. On the day of the polypectomy, simple X-ray images were taken to rule out colonic perforation, which revealed a large amount of intracolonic gas, but no free air in the subphrenic area. The next day of the procedure, subcutaneous emphysema was observed by the clinicians. Then abdomen computed tomography (CT) scan was performed, which showed diffuse bilateral retroperitoneal air extending to the mediastinum without intraperitoneal gas. The patient was discharged from the hospital after medical treatment and supportive care. We herein report a case of colonoscopic perforation in which pneumomediastinum, subcutaneous emphysema and peumoretroperitoneum occurred in the absence of pneumoperitoneum. The perforation was successfully treated with medical treatment and endoscopic clipping. Colonoscopists should not exclude colonic perforation even though free air on simple X-ray images is not visible.

( Yun Hyuk Yim ),( Hyo Keun Lee ),( June Sung Lee ),( Kyung Ah Kim ),( Nam Hoon Kim ),( Tae Jun Song ),( Won Ki Bae ) 대한내과학회 2011 대한내과학회 추계학술대회 Vol.2011 No.1

Colovesical fistula is a rare complication of inflammatory or neoplastic disease, and traumatic or iatrogenic injuries. Among them, sigmoid diverticulitis is the most frequent cause of colovesical fistula. There are few reported cases of the colovesical fistula in Korean literature, that is probably because the left colonic diverticulum is not common in Korea. We present here a case of patient with colovesical fistula complicated by sigmoid diverticulitis. A 66-year-old male patient was transferred to our hospital due to complaining of abdominal pain and mucoid stool. An abdominal and pelvic CT scan revealed diverticulitis and peridiverticular abscess in sigmoid colon. The patient was admitted and treated with intravenous antibiotic agents for four weeks, followed by oral antibiotic therapy. Six weeks after being discharged from the hospital, he was admitted again with complaints of pneumaturia, fecaluria, and dysuria. Follow up CT scan demonstrated fistula between sigmoid colon and bladder dome portion. Under the diagnosis of colovesical fistula due to diverticulitis of sigmoid colon, low anterior resection and partial cystectomy with cystostomy were performed.

<P><B>Purpose:</B></P><P>MicroRNAs (miRNAs) in biological fluids are potential biomarkers for the diagnosis and assessment of urological diseases such as benign prostatic hyperplasia (BPH) and prostate cancer (PCa). The aim of the study was to identify and validate urinary cell-free miRNAs that can segregate patients with PCa from those with BPH. </P><P><B>Methods:</B></P><P>In total, 1,052 urine, 150 serum, and 150 prostate tissue samples from patients with PCa or BPH were used in the study. A urine-based miRNA microarray analysis suggested the presence of differentially expressed urinary miRNAs in patients with PCa, and these were further validated in three independent PCa cohorts, using a quantitative reverse transcriptionpolymerase chain reaction analysis. </P><P><B>Results:</B></P><P>The expression levels of hsa-miR-615-3p, hsv1-miR-H18, hsv2-miR-H9-5p, and hsa-miR-4316 were significantly higher in urine samples of patients with PCa than in those of BPH controls. In particular, herpes simplex virus (hsv)-derived hsv1-miR-H18 and hsv2-miR-H9-5p showed better diagnostic performance than did the serum prostate-specific antigen (PSA) test for patients in the PSA gray zone. Furthermore, a combination of urinary hsv2-miR-H9-5p with serum PSA showed high sensitivity and specificity, providing a potential clinical benefit by reducing unnecessary biopsies. </P><P><B>Conclusions:</B></P><P>Our findings showed that hsv-encoded hsv1-miR-H18 and hsv2-miR-H9-5p are significantly associated with PCa and can facilitate early diagnosis of PCa for patients within the serum PSA gray zone.</P>

Expression, purification, and characterization of a dentin phosphoprotein produced by Escherichia coli, and its odontoblastic differentiation effects on human dental pulp cells.

Yun, Ye-Rang,Jeon, Eunyi,Lee, Sujin,Kang, Wonmo,Kim, Sang-Gi,Kim, Hae-Won,Suh, Chang Kook,Jang, Jun-Hyeog Kluwer Academic/Plenum 2012 The Protein Journal Vol.31 No.6

<P>To investigate the functions of recombinant human dentin phosphoprotein (rhDPP), we examined cell adhesion, viability and the odontoblastic differentiation activity of human dental pulp cells (hDPCs). Firstly, rhDPP was constructed using pBAD-HisA plasmid in Escherichia coli. Cell adhesion and viability of hDPCs by rhDPP was examined using a crystal violet assay and a MTT assay, ALP, mineralization activity and odontoblastic differentiation-related mRNA levels of hDPCs were measured to elucidate the odontoblastic differentiation effect of rhDPP on hDPCs. Initially, rhDPP significantly and dose-dependently increased hDPCs adhesion versus the untreated control (p < 0.05). Cell viability was also significantly increased by rhDPP at 5 days (p < 0.001). Furthermore, the odontoblastic differentiation effect of rhDPP was verified by measuring ALP activity, mineralization activity and the mRNA levels of odontoblastic differentiation markers. Taken together, rhDPP is expected to play an important role on hDPCs, thereby suggesting its potential use for tooth repair and regeneration.</P>
