A 21-year-old female Halla Horse weighing 248 kg was referred to the Jeju National University Equine Hospital with the chief complaint of anorexia accompanied by general weakness and depression for the previous three days suspected to be related to colic. Extensive diagnostic tests were performed for the following six days, including complete blood count (CBC), serum chemistry, gastroscopy, x-rays, and ultrasound imaging. The signalment, history, symptoms, and test results strongly suggested a chronic intestinal inflammatory disease with or without an alimentary tumor; hence, an exploratory laparotomy was performed. Almost the entire small intestine wall was severely thickened with diffuse ecchymosis on the serosa and protruded nodules on the mucosa. A presumptive diagnosis of an intestinal tumor was made, and the patient was euthanized, considering the patient's welfare with poor prognosis and low expectancy. A massive part of the small intestine was collected and submitted for macroscopic and microscopic pathology evaluations. The pathologic examination, including immunohistochemistry (IHC), indicated equine intestinal lymphoma showing strong positivity for T cell marker. This report describes the clinical signs, diagnosis and pathological features of intestinal lymphoma in a Halla Horse in detail.

Intestinal obstruction is not uncommon in infants. The common causes of intestinal obstruction in the neonatal period are Hirschsprung disease, intestinal atresia, meconium ileus, and intussusception. However, small bowel obstruction caused by a congenital band is very rare. We report a 27-day-old baby who was admitted with abdominal distension and fever. The abdominal X-ray revealed massive bowel dilatation and the contrast gastrografin enema suggested a distal small bowel obstruction. The explolaparotomy showed small bowel entrapment due to an unusual anomalous congenital band.

$Drosophila$ $melanogaster$ has been used as a useful model to study development and disease. In this study, we established the primary culture method of $Drosophila$ in the intestine to understand how intestinal stem cells (ISCs) mediate tissue repair during infection and disease. To obtain intestinal cells, we separated intestines from adult flies and isolated single cells by enzymatic treatment. The survival of cultured cells was measured using MTS-analysis. The maximum growth rate of the cells was observed on the 9th day after seeding. In addition, the presence of ISCs and enteroendocrine cells was confirmed by delta and prospero staining. Accordingly, we supposed that $Drosophila$ $melanogaster$ gut cells established in this study are probably useful in studies about intestinal stem cell regulation and various diseases occurring in the intestine.

Intestinal neuronal dysplasia (IND) is a disorder of abnormal intestinal innervation resulting in dysfunctional colonic motility. IND shares clinical features with Hirschsprung's disease but differentiated by histological findings such as hyperplasia of submucosal and myenteric plexuses, giant ganglia, ectopic ganglion cell and increased acetylcholinesterase activity in lamina propria. Although IND may exist as an isolated condition, more commonly, it occurs in association with Hirschsprung's disease. We report a case of twins affected with IND. Both children manifested with delayed passage of meconium and severe abdominal distention after birth. Barium enema in both patients showed microcolon. They underwent emergency ileostomy under the impression of total aganglionosis. But surgical biopsy specimens showed hyperganglionosis in submucosa with formation of giant ganglia. Both neonates suffers from several episodes of peudo-obstruction after the repair operation of colostomy.

The purpose of this study was to investigate the effects of intestinal bacteria on the growth of enteric bacteria, especially infectious harmful bacteria such as food poisoning, gastritis and enteritis, and the growth of beneficial bacteria. By dividing the rat into three test groups; normal control group, Loperamide-treated group, and supercritical heat-treated radish complex extracts(HRE)-treated group, animal experiments were performed to inhibit the growth of harmful bacteria without affecting the growth of beneficial bacteria in the intestine. It was found that it can be usefully used as an effective and safe health food composition for improving intestinal function and bacterial intestinal disease. In particular, it can be concluded that supercritical heat-treated radish complex extract is a safe food that does not show any side effects even when taken for a long time.

While the survival of extremely premature infants with respiratory distress syndrome has increased due to advanced respiratory care in recent years, necrotizing enterocolitis (NEC) remains the leading cause of neonatal mortality and morbidity. NEC is more prevalent in lower gestational age and lower birth weight groups. It is characterized by various degrees of mucosal or transmural necrosis of the intestine. Its exact pathogenesis remains unclear, but prematurity, enteral feeding, bacterial products, and intestinal ischemia have all been shown to cause activation of the inflammatory cascade, which is known as the final common pathway of intestinal injury. Awareness of the risk factors for NEC; practices to reduce the risk, including early trophic feeding with breast milk and following the established feeding guidelines; and administration of probiotics have been shown to reduce the incidence of NEC. Despite advancements in the knowledge and understanding of the pathophysiology of NEC, there is currently no universal prevention measure for this serious and often fatal disease. Therefore, new potential techniques to detect early biomarkers or factors specific to intestinal inflammation, as well as further strategies to prevent the activation of the inflammatory cascade, which is important for disease progression, should be investigated.

Background: Damage to the healthy intestinal epithelial layer and regulation of the intestinal immune system, closely interrelated, are considered pivotal parts of the curative treatment for inflammatory bowel disease (IBD). Plant-based diets and phytochemicals can support the immune microenvironment in the intestinal epithelial barrier for a balanced immune system by improving the intestinal microecological balance and may have therapeutic potential in colitis. However, there have been only a few reports on the therapeutic potential of plant-derived exosome-like nanoparticles (PENs) and the underlying mechanism in colitis. This study aimed to assess the therapeutic effect of PENs from Panax ginseng, ginseng-derived exosome-like nanoparticles (GENs), in a mouse model of IBD, with a focus on the intestinal immune microenvironment. Method: To evaluate the anti-inflammatory effect of GENs on acute colitis, we treated GENs in Caco2 and lipopolysaccharide (LPS) -induced RAW 264.7 macrophages and analyzed the gene expression of proinflammatory cytokines and anti-inflammatory cytokines such as TNF-α, IL-6, and IL-10 by real-time PCR (RT-PCR). Furthermore, we further examined bacterial DNA from feces and determined the alteration of gut microbiota composition in DSS-induced colitis mice after administration of GENs through 16S rRNA gene sequencing analysis. Result: GENs with low toxicity showed a long-lasting intestinal retention effect for 48 h, which could lead to effective suppression of pro-inflammatory cytokines such as TNF-α and IL-6 production through inhibition of NF-κB in DSS-induced colitis. As a result, it showed longer colon length and suppressed thickening of the colon wall in the mice treated with GENs. Due to the amelioration of the progression of DSS-induced colitis with GENs treatment, the prolonged survival rate was observed for 17 days compared to 9 days in the PBS-treated group. In the gut microbiota analysis, the ratio of Firmicutes/Bacteroidota was decreased, which means GENs have therapeutic effectiveness against IBD. Ingesting GENs would be expected to slow colitis progression, strengthen the gut microbiota, and maintain gut homeostasis by preventing bacterial dysbiosis. Conclusion: GENs have a therapeutic effect on colitis through modulation of the intestinal microbiota and immune microenvironment. GENs not only ameliorate the inflammation in the damaged intestine by downregulating pro-inflammatory cytokines but also help balance the microbiota on the intestinal barrier and thereby improve the digestive system.

Intestinal tuberculosis is an infection of the gastrointestinal tract by the Mycobacterium tuberculosis complex. To the best of our knowledge, solitary intestinal tuberculosis accompanied by intestinal obstruction, particularly in the middle of the small intestine, is extremely rare. We report a case of solitary jejunal tuberculosis in a 49-year-old man with no underlying disease. He was admitted a few days after the onset of diffuse abdominal discomfort. Upon evaluation, we initially considered a malignancy of the distal jejunum with ileus due to the presence of a mass. Therefore, he underwent laparoscopic resection of the small bowel. Unexpectedly, the histologic specimen showed a chronic caseating granulomatous lesion with acid-fast bacilli. Ultimately, he was diagnosed with solitary jejunal tuberculosis. He was successfully treated with anti-tuberculosis drugs without any complications.

Studies on diagnosis and treatment of tumor . abscess . ulcer in intestinal carbuncle were carried out. The result of studies were summerized as follows: 1. By Nai-Gyung carbuncle-tumor arose from disharmony between nutrient and defensive because of cold, abscess arose from fever victory between cold and fever, ulcer arose from decreasing function of Bi-Kam year. By latter literature Bi-Kam year could be interpreted that spleen stomach was invaded evil influence from unattainable vital force of the earth. 2. Sites of intestinal carbuncle were large intestine, small intestine, intestinal inside or outside between large and small intestine, Intestinal carbuncle was common name of a disease about large intestinal carbuncle, small intestinal carbuncle, pelvic intestinal carbuncle, shrink leg intestinal carbuncle etc.. Pain appeared Chunchu-Hyul in large intestinal carbuncle, and Gwanweon-Hyul in small intestinal carbuncle. 3. On abdominal diagnosis tumor had indistinct pain of Gwanweon Chunchu, edema and heary feeling in low abdomen, no excessive pain by hand press and intestinal boiling sound. In abscess pain descended from right side of low abdomen to huckle, and there was rejection against press, feeling about fever,water sound with flank movement. In ulcer hand approach was difficult since excessive pain diffuse to whole abdomen, and perforating ulcer sometimes caused a serious symptom of umbilical pus. 4. On fecal and urinary diagnosis in tumor urine was yellowish red pollakiuria like gonorrhoea and occasional constipation. In abscess uncomfortable rough pain short red early urine like gonorrhoea appeared during urination, and constipation with stinging pain appeared during defecation. In ulcer red rough pyuria appeared, and stinging and pain with puruloid blood appeared during defecation. 5. On treatment in tumor Daiwhang-Tang Daisenggi-Tang Dangui-Jun by dissipation method, calming down method, interior reliance maturation method, in abscess Mokdan-San Euiiin-Tang Jeokduiin-Tang by the method of water repelling pus discharge, acute breaking, in ulcer Takridanggui-Tang Paljin-Tang Bojungikki-Tang were each used by the method of interior reliance, virulence astriction, supplement vital force and blood, supplement spleen stomach. 6. On treatment patient may have to be careful of excessive moving and suprising anxiety. Abuse of acupuncture and moxibustion made patient worse, misuse of analgesics purgative intestinal irrigation etc. could provoke difficult diagnosis and perforation. So you must treat after exact diagnosis. 7. Prognosis of ease tumor ease abscess ease ulcer and ease astriction was good. If the intestinal carbuncle were not to promote to abscess and ulcer for a long time, its prognosis was bad and it could metastasize to cancer because of dark purple with hardness. So tumor abscess ulcer in intestinal carbuncle may be significant of precancerous lesion.

The frequency and severity of intestinal tuberculosis are decreased due to socioeconomic development, pasteurization of milk and more effective anti-tuberculous chemotherapy. But in recent year, HIV-infected patients are known to be at high risk of developing tuberculosis. The pathogenesis of intestinal tuberculosis is dependent on a immune state and nutritional status of the patient, the tuberculosis amount of sputum and tuberculosis toxicity. The diagnosis of intestinal tuberculosis is usually difficult because of non-specific clinical features and radiological signs. Chronic diarrhea in intestinal tuberculosis is able to produce a malnutrition, marasmus, kwashiorkor or the combined form. The treatment is anti-tuberculous chemotherapy for 12~24 months, but operation should be considered to intestinal perforation, obstruction, fistula formation and massive bleeding. The study about kwashiorkor in intestinal tuberculosis is rare in recent years, we should remind that tuberculosis is still prevalent disease in Korea. We report a ten year-old boy with ileocecal tuberculosis who presented with kwashiorkor, severe malnutrition with review of literature.
