Colorectal cancers often invade adjacent organs; however, direct duodenal invasion is rare. Adenocarcinoma is the most common type of colorectal cancer, but an undifferentiated carcinoma type is unusual. Herein, we present a case of undifferentiated carcinoma of the colon that directly invaded the duodenum and metastasized to distant lymph nodes. An 85-year-old female patient was admitted with a 7-cm-sized colonic mass invading the duodenum, detected by computed tomography. Positron emission tomography revealed fluorodeoxyglucose uptake in the colon, duodenum, and aortocaval lymph nodes. A large encircling mass in the ascending colon and an ulcerated mass in the duodenum were revealed by colonoscopy and esophagogastroduodenoscopy, respectively. Pathologic examinations of the colon and the duodenum revealed nonglandular, diffusely infiltrating atypical round cells, confirming undifferentiated carcinoma of the colon. The histologic type of this tumor was distinguished using immunohistochemical (IHC) markers. Finally, microscopic characteristics and IHC markers aided in identifying the histologic type of colorectal cancer.

An 8-year-old, female Pointer dog was presented with weight loss, hematochezia, and dyschezia. For the diagnosis, physical examination, complete blood counts, serum chemistry, radiography, ultrasonography, computed tomography, colonoscopy, cytology and histopathological examination were performed. The complete blood counts and serum biochemistry results were within the reference range. Ultrasonographic findings were presented with the thickened wall of the colon and rectum. Colonoscopy revealed irregular and ulcerated mucosal surface, mass and luminal narrowing of colorectal lesions. There were thickened wall and contrast enhancement of the lesion in colorectal region on the computed tomography. The cytologic examination suggested the adenocarcinoma. Postmortem histopathologic examination revealed adenocarcinoma. Based on these findings, the dog was diagnosed with annular colorectal adenocarcinoma.

Mucinous adenocarcinoma occurs in 1.6-25.4% of patients with colorectal cancer. We report a case of a 27-year-old man with negative findings on initial colonoscopic biopsy, but finally diagnosed with mucinous adenocarcinoma of the colon. After undergoing an abdominal CT due to persistent abdominal pain, he was transferred to our hospital. The abdominal CT showed a diffuse and irregular wall thickening in the distal transverse colon. Due to the edema and stenosis of colonic wall, it was difficult to insert the colonoscope into the proximal region; a biopsy revealed chronic colitis with lymphofollicular hyperplasia. Transverse colectomy and lymph node dissection were performed. The diagnosis was mucinous adenocarcinoma of approximately 20×4.5 cm. Compared to adenocarcinoma, mucinous adenocarcinoma is found in a younger population with an advanced stage and is less responsive to palliative chemotherapy. Therefore, recalcitrant abdominal pain even in young people warrants early detection through appropriate examinations such as abdominal CT and colonoscopy.

The purpose of the study was to verify if or not as funtional food by estimating antitumor activity and antimicrobial activity of Coriolus versicolor(Fr.)Quel and Ganoderma Lucidum (Fr.)Karst. 1. The contents of moisture. crude fiber and crude protein of GL were higher $(18.28\%,\;10.3\%,\;78.4\%)$ than that of CV, but the content of crude lipid GL was higher than that of CV. 2. Inhibitory effects of on the growth of AGS human gastric adenocarcinoma cells and HT-29 human colon adenocarcinoma cell were increased by increasing of concentration in added methanol extracts of CV and GL. 3. Antimicrobial activity on Escherichia col1; Staphylococcus aureus, Salmonella typhimurium existed methanol extracts of CV. Therefore. it is suggested that CV is worth as functional food.

Mucinous adenocarcinoma (MAC) is a rare malignant neoplasm that occasionally occurs in the large intestine (colon), followed by the pancreas, ovary, lung, prostate, and breast. It is characterized by large amounts of extracellular epithelial mucin that contains tumor cell nests. We herein present a unique case of MAC originating from minor salivary gland, the second to be reported in literature in South Korea. We report a case of MAC in the tongue considered to be developed from minor salivary gland with a review of literature.

This study is aimed to investigate the effects of intravenous Cultivated Wild Ginseng Pharmacopuncture(CWGP) and the FOLFIRI chemotherapy combination on recurred and metastatic ascending colon cancer patient. A 42-years-old man was diagnosed as ascending colon adenocarcinoma on 9th Mar. 2011. After performing right hemicolectomy and 12 cycles of FOLFOX chemotherapy recurrence at hemicolectomy site and metastases in liver, spleen and lungs were found on 7th Feb. 2012. Intravenous CWGP were performed during total 12 cycles of FOLFIRI chemotherapy from 3rd Mar. 2012 to 27th Sep. 2012. The effects and toxicities of CWGP and FOLFIRI chemotherapy combination were evaluated with PET torso(AA) and National Cancer Institute-Common Toxicity Criteria. The tumor mass in the splenic hilum and liver S4 was disappeared and multiple pulmonic lymph nodules were decreased in size. The recurred lesion on the site of right hemicolectomy showed no changes. During the treatment the patient had no toxicity over grade 1.

We present a patient with metastatic colon carcinoma who developed paraplegia following a neurolytic splanchnic block. A 41-year old man with metastatic adenocarcinoma of the colon received a splanchnic neurolytic block using alcohol because of severe abdominal pain. Bilateral motor weakness and a sensorial deficit in both legs developed after the procedure. Diffusion magnetic resonance imaging revealed spinal cord ischemia between T8 and L1. The motor and sensorial deficits were almost completely resolved at the end of the third month. We think that anterior spinal artery syndrome due to reversible spasms of the lumbar radicular arteries using alcohol have resulted in transient paraplegia. The retrograde spread of alcohol to neural structures may have also contributed.

For probing the importance of planarity of imidazolidinone motif of 4-phenyl-1-(N-acylindoline-5-sulfonyl)imidazolidinones 1 for their cytotoxicity, 4-phenyl-1-(N-acylindoline-5-sulfonyl)[1,2,5]thiadiazolidine-1,1-dioxides 2 were prepared and their cytotoxicity were measured against human lung carcinoma (A549), human colon carcinoma (COLO205), human ovarian cancer (SK-OV-3), human leukemic cancer (K562), and murine colon adenocarcinoma (Colon26) cell lines in vitro. Although only carbonyl moiety of imidazolidinone ring was replaced with sulfonyl group, compounds 2 do not show any activity against all five cancer cell lines unlike 1. Therefore the planarity of imidazolidinone ring of 1 should be an important factor for their cytotoxic activity.

The anti proliferative effects of bile acids and their derivatives on HT -29 human colon cancer cells were investigated. Ursodeoxycholic acid (UDCA) and its synthetic derivatives, HS-1030 and HS-1183, and chenodeoxycholic acid (CDCA) and its synthetic derivatives, HS-1199 and HS-1200 were employed for this study. General evaluations focusing on cell cycle were conducted in HT -29 human colon adenocarcinoma cell line (p53 mutant type). (omitted)

Objective: The aim of present study was to assess the anti-oxidant potential of water-soluble peptides (WSPs) extract derived from buffalo and cow milk Cheddar cheeses at different stages of ripening. Methods: The antioxidant potential of WSPs extract was assessed through 2,2'-azinobis-3-ethylbenzothiazoline-6sulfonic acid (ABTS)-radical scavenging activity. In addition, impact of WSPs extract on cell viability and production of reactive oxygen species (ROS) in human colon adenocarcinoma Caco-2 (tert-butylhydroperoxide-induced) cell lines was also evaluated. Results: The ABTS-radical scavenging activity increased progressively with ripening period and dose-dependently in both cheeses. However, peptide extract from buffalo milk Cheddar cheese demonstrated relatively higher activity due to higher contents of water-soluble nitrogen. Intracellular ROS production in Caco-2 cells decreased significantly (p<0.05) till 150th day of cheese ripening and remained constant thereafter. Additionally, dose-dependent response of WSPs extract on antioxidant activity was noticed in the Caco-2 cell line. Conclusion: On the basis of current in vitro study, the Cheddar cheese WSPs extract can protect intestinal epithelium against oxidative stress due to their antioxidant activity.
