The purpose of this study was to determine the usefluness of the UGI study with Carboxy-Methylcellulose (CMC) and 140% barium in the patient undergone gastrectomy We reviewed the UGI study with effervescent agent and barium and the UGI study with CMC and 140% barium of twenty one patients, undergone gastrectomy (Billroth-Ⅱ:12, Billroth-Ⅰ:4 total gastrectomy:5). The average interval between these studies was 19 months. The coating quality of the remnant stomach, anastomosis sit e, jejunum and proximal ileum in two studies were compared. The maximum luminal diameter of the same site and the maximum distance between a adjacent valvulae conniventes were measured for evaluating the distensibility of these studies. Compared with the coating quality of the remnant stomach, the UGI study with effervescent agent and barium was superior to the UGI study with C MC and barium in 68% (11/16) patients. The difference of coating quality between these studies was marginal in the anastomosis site and jejunum. The UGI study with CMC and barium provided a better coating quality in the proximal ileum of 95%(20/21). The maximum luminal diameter of the anastomosis site, jejunum and proximal ileum was respectively 2.75cm, 3.36cm, and 2.82cm inthe UGI study with effervescent agent and barium, 3.2cm 3.35cm, and 3.40cm in the UGI study with CMC and barium(p〈0.01). The maximum distance between a adjacent valvulae conniventes of the jejunum and proximal ileum was respectively 0.61cm and 0.51cm in the UGI study with effervesent agent and barium, 0.74cm and 0.72cm in the UBI study with CMC and barium (p〈0.05). Compared with the distensibility, the UGI study with CMC and barium was superior. The UGI study with CMC and barium in subjects, undergone gastectomy, showed the advantage the mucosa distal to anastomosis site except for the remnant stomach and must be supply the more information in finding lesion such as adhesion and peritoneal dissemination.

In order to restore the vegetation that was demolished by imported goats in Ogasawara Islands, the damaged States in Mukogima, Nakoudogima, Yomegima and Nishigima island that were badly damaged among Ogasawara Islands were investigated, and the removal method of goats, the counterplan for restoration of vegetation and restoration technique for vegetation were inquired. The results obtained are as follows; 1. The temperature and amount of pricipitation of the yearly mean in Ogasawara were 23℃ and 1229.1mm respectively, and this Islands were belonged to the oceanic subtropical zone. 2. The main vegetation in four island were Pisonia umbellifera,Callicarpa subpubescens, Ochrosia nakaiana, Livistonia chinensis, Drypetes integerrima, Pandanus boninensis, Terenna subsessilis, Sporobolus diander, Oplismenus compositus, Gramineae spp. etc. 3. The vegetation and top soil in four islands were extinct by eating and over-walks of goats and severely washed out by rainfall and wind. 4. The number of goats were increased yearly, and were 766 in Mukogima, 189 in Nakoudogoma, 92 in Yomegima and 41 in Nishigima in 1997, respectively. 5. To control goats and to restore the vegetation, the fence was set up in the place was badly damaged by goats. 6. Within the fence to control goats, sand bag method to soil erosion, small dam, vegetation mat method and seed spray method were treated with.

Tracheal intubation is accompanied by varying degrees of sympathetic stimulation as reflected by increases in blood pressure and heart rate. Several clinical trials to reduce these effects by deepening anesthesia, using pharmacologic agents such as alpha and beta blockers,calcium channel blockers, fentanyl and lidocaine have been reported. To evaluate the effects of slow induction and fentanyl on responses of cardiovascular system induced by endotracheal intubation, we administered thiopental sodium 5㎎/㎏ (group Ⅰ), slow induction with O_(2)-N_(2)O-halothane( group Ⅱ), fentanyl 3uμ/㎏ with thiopental sodium 4㎎/㎏(group Ⅲ) for induction of anesthesia, and measured systolic and diastolic pressures, and heart rates before induction, and at 1,2,3,4, and 5 minutes after intubation. 1) In group Ⅰ, intubation caused a significant increase in systolic pressure (10%) diastolic pressure (15%) and heart rate (28%) at 1 min. after intubation but each parameter returned to the normal level within 5 min. 2) In group Ⅱ, increases in systolic pressure (12%), diastolic pressure (22%) and heart rate (23%) at 1 min. after intubation but there were no significant differences compared to group Ⅰ. 3) In group Ⅲ, the increase in systolic and diastolic pressure induced by intubation was abolished by fentanyl and showed significant decrease compared to group Ⅱ, increase in heart rate (4%) at 1 min. after intubation but were of no significance, and showed significant decrease compared to group Ⅱ but not at 3 min., 4 min. after intubation. These results suggested that a low dose of fentanyl significantly blunts postintubation hypertenion and tachycardia when used as an adjunct to thiopental sodium.

This study was conducted to investigated the major characteristics of genetically modified rice of "Milyang 204" originated from Dongjinbyeo compared to a non-transgenic rice varieties Dongjinbyeo and Junambyeo. Basta resistant transgenic rice lines carrying bar gene produced by the Yeongnam Agricultural Research Institute were evaluated for their agronomic characters. The transgenic Japonica rice of "Milyang 204" showed inferior phenotypic traits compared to a non-transgenic rice variety Dongjinbyeo and Junambyeo. On the basis of UPOV (Union Internationale Pour la Protaection des Obtentions Vegetables) and NSMO(National Seed Management Office) the transgenic "Milyang 204" showed difference in some traits out of some agronomic traits, such as leaf color, angle of flag leaf, number of spikelets, culm length, white core and white belly compared to the nontransgenic varieties rice.
Hyphantria cunea hemocytic STAT is activated in response to microorganism infection
Yong Min Kwon,Hong Ja Kim,Yong Il Kim,In Hee Lee,Byung Rae Jin,Yeon Soo Han,Hyang Mi Cheon,Young Jin Kang,Sook Jae Seo 한국응용곤충학회 2010 한국응용곤충학회 학술대회논문집 Vol.2010 No.05
A new insect member of the STAT family of transcription factors (HcSTAT) has been cloned from the lepidopteran, Hyphantria cunea. The domain involved in DNA interaction and the SH2 domain are well conserved. The gene is transcribed at a low level during all stages of development, and transcribed in hemocyte, fat body, midgut, epidermis, and Malpighian tubule. Especially, hemocyte and Malpighian tubule showed transcriptional activation of HcSTAT upon Gram-negative and -positive bacteria challenge. Gram-negative and -positive bacteria challenge specifically results in nuclear translocation of HcSTAT protein and induction of DNA-binding activity that recognizes a STAT target site in H. cunea hemocyte. In vivo treatment with sodium orthovanadatetranslocates HcSTAT to the nucleus in hemocyte cells.

Backgrounds/Aims: Pneumatosis intestinalis (PI) is a condition in which multiple gas-filled mural cysts develop in the gastrointestinal tract. Although its exact etiology remains obscure, PI is rarely observed in liver transplant (LT) recipients. Methods: In 317 cases of adult living donor LT (LDLT) performed during 2011, PI developed in three patients during the 3 year follow-up. Results: Of these three patients, the two who demonstrated PI at 6 weeks and 2 months after LT, respectively, were asymptomatic and showed no signs of secondary complications. Diagnosis was made incidentally using abdominal radiographs and computed tomography (CT) scans. PI was identified in the right ascending colon with concomitant pneumoperitoneum. These two patients received supportive care and maintained a regular diet. Follow-up CT scans demonstrated spontaneous resolution of PI with no complications. The third patient was admitted to the emergency room 30 months after LDLT. His symptoms included poor oral intake and intermittent abdominal pain with no passage of gas. Abdominal radiography and CT scans demonstrated PI in the entire small bowel, with small bowel dilatation, pneumoperitoneum, and pneumoretroperitoneum, but no peritonitis. Physical examination revealed abdominal distension but no tenderness or rebound tenderness. After 1 week of conservative treatment, including bowel rest and antibiotics therapy, PI and pneumoperitoneum resolved spontaneously without complications. Conclusions: We suggest that adult LDLT recipients who develop asymptomatic or symptomatic PI with no signs of secondary complications can be successfully managed with conservative treatment.
