  • Intestinal giant-cystic disease (IGCD) of the Israel carp (Cyprinus carpio nudus) has been recognized as one of the most serious diseases afflicting inland farmed fish in the Republic of Korea, and Thelohanellus kitauei has been identified as the causative agent of the disease. Until now, studies concerning IGCD caused by T. kitauei in the Israel carp have been limited to morphological and histopathological examinations. However, these types of diagnostic examinations are relatively time-consuming, and the infection frequently cannot be detected in its early stages. In this study, we cloned the full-length 18S rRNA gene of T. kitauei isolated from diseased Israel carps, and carried out molecular identification by comparing the sequence with those of other myxosporeans. Moreover, conventional PCR and real-time quantitative PCR (qPCR) using oligonucleotide primers for the amplification of 18S rRNA gene fragment were established for further use as methods for rapid diagnosis of IGCD. Our results demonstrated that both the conventional PCR and real-time quantitative PCR systems applied herein are effective for rapid detection of T. kitauei spores in fish tissues and environmental water.

  • $Neodiplostomum$ $seoulense$ (Digenea: Neodiplostomidae) is an intestinal trematode that can cause severe mucosal pathology in the small intestines of mice and even mortality of the infected mice within 28 days after infection. We observed neuronal growth associated protein-43 (GAP-43) expression in the myenteric plexus of the small intestinal wall of $N.$ $seoulense$-infected mice until day 35 post-infection (PI). BALB/c mice were infected with 200 or 500 $N.$ $seoulense$ metacercariae isolated from naturally infected snakes and were killed every 7 days for immunohistochemical demonstration of GAP-43 in the small intestines. $N.$ $seoulense$-infected mice showed remarkable dilatation of intestinal loops compared with control mice through days 7-28 PI. Conversely, GAP-43 expression in the mucosal myenteric plexus was markedly ($P$<0.05) reduced in the small intestines of $N.$ $seoulense$-infected mice during days 7-28 PI and was slightly normalized at day 35 PI. From this study, it is evident that neuronal damage occurs in the intestinal mucosa of $N.$ $seoulense$-infected mice. However, the correlation between intestinal pathology, including the loop dilatation, and depressed GAP-43 expression remains to be elucidated.

  • The immune response against Trichinella spiralis at the intestinal level depends on the $CD4^+$ T cells, which can both suppress or promote the inflammatory response through the synthesis of diverse cytokines. During the intestinal phase, the immune response is mixed (Th1/Th2) with the initial predominance of the Th1 response and the subsequent domination of Th2 response, which favor the development of intestinal pathology. In this context, the glucocorticoids (GC) are the pharmacotherapy for the intestinal inflammatory response in trichinellosis. However, its therapeutic use is limited, since studies have shown that treatment with GC suppresses the host immune system, favoring T. spiralis infection. In the search for novel pharmacological strategies that inhibit the Th1 immune response (proinflammatory) and assist the host against T. spiralis infection, recent studies showed that resiniferatoxin (RTX) had anti-inflammatory activity, which decreased the serum levels of IL-12, $INF-{\gamma}$, $IL-1{\beta}$, $TNF-{\alpha}$, NO, and $PGE_2$, as well the number of eosinophils in the blood, associated with decreased intestinal pathology and muscle parasite burden. These researches demonstrate that RTX is capable to inhibit the production of Th1 cytokines, contributing to the defense against T. spiralis infection, which places it as a new potential drug modulator of the immune response.

  • Sinonasal intestinal-type adenocarcinoma is a rare neoplasm which can be diagnosed by pathologic report. Nasal obstruction, epistaxis, and rhinorrhea are common symptoms, but presenting with a benign-looking palpable mass is also possible. This is a report of our experience in diagnosing and treating a sinonasal intestinal-type low grade adenocarcinoma. A 63-year-old man initially presented with a rapidly growing palpable mass in the glabella region for 4 months. A malignancy of sinus origin was suspected on imaging studies. We performed further preoperative evaluations for cancer staging, and curative surgery was planned. Radical resection and immediate reconstruction with free anterolateral thigh flap were performed. The pathology findings confirmed a diagnosis of sinonasal intestinal-type adenocarcinoma.

  • 목 적: 본 연구에서는 방사선에 의한 장점막 손상에 대한 5-androstendiol (5-AED)의 장점막 보호효과 여부를 마우스 위장관 조직에서 평가하여 방사선 보호제로서의 적용가능성을 모색하고자 하였다. 대상 및 방법: 30마리의 C3H/HeN 마우스를 대조군, 방사선 조사군, 방사선 조사 전 5-AED 처리군으로 나누어, 5 Gy와 10 Gy 전신방사선 조사하였다. 5-AED는 방사선 조사 24시간 전에 체중 당 50 mg/kg으로 피하 주사하였다. 10 Gy 전신 방사선 조사 후 3.5일에 마우스를 희생하여 공장조직을 채취하여 소장움 생존, 융모의 개수, 융모의 높이, 소장움의 크기, 10개 장상피세포 당 기저층의 길이를 측정하여 장점막 손상정도를 비교 평가하였다. 또한 apoptosis의 발생빈도수는 5 Gy 방사선 조사 후 12시간에 TUNEL 방법으로 검수하였다. 결 과: 10 Gy 방사선조사 전 5-AED 투여군에서, 방사선 조사군과 비교하여, 소장움의 소실이 상대적으로 적고 융모의 높이가 유의성 있게 증가하였다. 5-AED 전처치군에서 소장움의 크기가 방사선 조사군에 비교하여 증가하였고, 10개의 장 상피세포 당 기저층 길이는 5-AED 전처치군에서 감소함을 관찰하여 소장조직의 방사선 손상에 대해 5-AED의 보호효과가 있음을 확인하였다. 방사선 조사 시 증가한 apoptosis에 대해서는 5-AED의 투여가 유의성 있는 감소 효과를 나타내지 못하였다. 결 론: 5-AED 투여는 방사선에 의한 소장점막의 형태학적인 손상변화에 대해 보호효과가 있으며, 이러한 결과는 방사선 조사 전 5-AED 투여가 방사선에 의한 장점막 손상에 대한 보호약물로 활용될 수 있는 가능성을 제시한다.

  • Helicobacter pylori (H. pylori) infection is uncommon in developed countries, yet is common in underdeveloped and developing countries. Infection rate of H. pylori is minimally influenced by economic, environmental, and public health status and genetic factors. Korea is a developing country with a high incidence of H. pylori infection and gastric carcinoma, which is one of the leading causes of death. For this reason, accurate clinical and pathologic data on H. pylori-associated disease are very important. Intestinal metaplasia accompanies chronic gastritis and increases the risk of gastric carcinoma. For this reason, the relationship between H. pylori infection and intestinal metaplasia is very closely linked. Because of this, as the antecedent condition is guessed, it examines the relationship of the H. pylori and the intestinal metaplasia. Intestinal metaplasia is thought to be the basis in the development of intestinal type gastric carcinomas. Recent investigations showed that inflammatory reaction in the gastric fundus affect the development of gastric carcinogenesis. To verify neutrophilic activity in the gastric fundus and development of intestinal metaplasia in both gastric fundus and antral mucosa, their relationship was studied using 159 healthy patients who had undergone gastric endoscopic biopsies without any identifiable pathologic disesaes. When neutrophilic activity accompanied, incidence of intestinal metaplasia was significantly increased (p<0.05). H. pylori infection was statistically and significantly associated with the presence of intestinal metaplasia (p<0.05). These results suggest that H. pylori infection affected the development of intestinal metaplasia in the stomach. These results will help our understanding of H. pylori infection in the pathogenesis of intestinal metaplasia, a preneoplastic condition of the stomach. To reduce the incidence of gastric adenocarcinoma, eradication treatment of H. pylori is recommended when there's a neutrophilic activity in the gastric fundus.

  • The aim of this study was to observe the effect of moxibustion at matched acupoints of ST36, ST37 and ST39 in rats with sex and age. This study measured small intestinal motility in rats. First, cauterize with moxa was applied to the ST36, ST37 and ST39 in rats classified by sex and age under enflurane anesthesia. And then same treatment is done to matched acupoints of ST36, ST37 and ST39. In each groups of ST36, ST37 and ST39, the small intestinal motility was increased in 5, 6, 8 weeks male and 5 weeks female rats at ST36, 6, 7 weeks male and 5, 6, 8 weeks female rats at ST37, 5, 6 weeks male and 5 weeks female rats at ST39. In matched acupoints, the small intestinal motility was increased in 5, 8 weeks male and 5, 6, 7, 8 weeks female rat at ST36+ST37, 5 weeks male and 6, 7, 8 weeks female rats at ST36+ST39, 5, 7 weeks male and 5, 8 weeks female rats at ST37+ST39. The effects of moxibustion at each acupoints decreased by advancing age and when these acupoints were combined, the effective results were shown in female rats of all age group. These results suggest that when each acupoints and matched acupoints was chosen in moxibustion treatment, the sex and age of individual is worth consideration.
