  • An 11-year-old intact male mixed-breed dog was referred for evaluation of a splenic mass. On radiographs, the cardiac apex, stomach, and head of the spleen were on the right and the descending colon was on the left of the midline. In addition, the left kidney was located more cranially than the right kidney. Standard two-dimensional echocardiographic images were obtained from each inverted left and right parasternal windows. Furthermore, the spleen was observed on the right side and a splenic mass was found on the splenic tail. Based on the radiographic and ultrasonographic characteristics of the patient, a diagnosis of situs inversus totalis (SIT) and a splenic mass was made, and splenic resection was performed successfully with no unexpected complications. The splenic mass was confirmed histopathologically as being marginal zone lymphoma (MZL). This report describes a dog with SIT and splenic MZL.

  • Carcinoembryonic antigen (CEA) levels were measured in the serum of 35 normal control subjects and 179 cases of various benign and malignant gastrointestinal diseases. Malignant gastrointestinal tumors include 69 cases of stomach cancer, 24 cases of hepatoma and 33 cases of colorectal cancer. Benign gastrointestinal diseases include 29 cases of peptic ulcer and 24 cases of liver cirrhosis. The results were as followings: 1) Mean serum CEA level in normal control subjects was $6.9{\pm}3.3ng/ml$ and there was; no difference in mean serum CEA level between age and sex difference. 2) In malignant gastrointestinal tumors, mean serum CEA level in colorectal cancer, hepatoma and stomach cancer, were $54.3{\pm}88.9ng/ml,\;62.1{\pm}99.7ng/ml$ respectively. Serum CEA level showed positive rate of 67% in colorectal cancer, 63% in hepatoma and 62% in stomach cancer. There was no difference in mean levels and positivity of serum CEA between these 3 malignant tumor groups. 3) Positivity of serum CEA was 61% in malignant gastrointestinal tumor group in spite of 37% in benign gastrointestinal disease group. In both mean level and positivity of serum CEA, stomach cancer was much higher than peptic ulcer. But there was no difference in mean level and positivity of serum CEA level between hepatoma and liver cirrhosis. 4) In hepatoma serum CEA level showed positive rate of 62.5% and alpha-feto protein showed a rate of 58.3%. 5) Mean serum CEA levels in patients with cancer in rectal, cecal, sigmoid colon, ascending: colon and descending colon were $73.7{\pm}106.7ng/ml,\;69{\pm}84.8ng/ml$, $15.7{\pm}9.1ng/ml,\;7.5{\pm}10.6ng/ml$ and 4.0ng/ml respectively. Positive rate of serum CEA showed 86% in sigmoid. colon cancer, 68% in rectal cancer and 66% in cecal cancer. 6) In considering of histological background, there was no correlation between the degree of differentiation of tumor cell and the serum CEA level in colorectal cancer. According to Duke's classification, the mean serum levels of CEA were $8.8{\pm}11.4ng/ml$ in group A, $15.3{\pm}16.0ng/ml$ in group B and $68.5{\pm}101.5ng/ml$ in group C respectively. Positivity-of serum CEA in group A, Band C were 40%, 50% & 69% respectively. So there was significant correlation between the degree of elevation of serum CEA and tumor extension.

  • Objectives: Dojeckjiyu-tang has been used to treat Hwaseol & Jeokri. The object of this study is examination of the treatment effect of Dojeckjiyu-tang for ulcerative colitis of the mouse descending colon. Methods and Materials : Twenty-one rats were divided into 3 groups and treated as follows: the control group was untreated mice. The UCE group was ulcerative colitis elicited mice. The DJT group was Dojeckjiyu-tang treated mice after ulcerative colitis elicitation. The groups were examined with common morphology, paneth cells in intestinal crypt, absorptive cells and goblet cells in epithelium, cell division in mucose, COX-1 as mucosal protector, COX-2 (which appears to play an important role in inflammation), IL-2R-, ICMA-1-inducing cellular immuno-chainreaction, and the distribution of apoptotic cells. Results: 1. The morphology of colonic mucosa from UCE mice: the disappearance of epithelium and intestinal propria in hemorrhagic erosions were seen, but in the morphology of colonic mucosa from DJT-treated mice, the configuration of epithelium and intestinal propria were the same as normal. 2. The distribution of goblet cells and absorptive cells with microvilli in intestinal propria from UCE mice: a noticeable decrease of goblet cells and absorptive cells with microvilli were seen, but with the distribution of goblet cells and absorptive cells with microvilli in intestinal propria from DJT -treated mice, the configuration of goblet cells and absorptive cells with microvilli were the same as normal. 3. The immunohistochemical stain for BrdD in colonic mucosa and COX-1 in lamina propria from UCE mice: BrdU positive cells and COX-1 positive cells in the region of hemorrhagic erosion disappeared, but in the immunohistochemical stain for BrdU in colonic mucosa and COX-1 in lamina propria from DIT-treated mice, BrdU positive cells and COX-1 positive cells were seen. 4. The immunohistochemical stain for COX-2 in lamina propria, IL-2R-in lamina propria, intestinal propria and submucosa and ICMA-1 in intestinal propria and submucosa from DCE mice: a noticeable increase COX-2, IL-2R-, ICMA-1 positive cells were seen, but in the immunohistochemical stain for COX-2 in lamina propria, IL-2R-in lamina propria, intestinal propria and submucosa and ICMA-1 in intestinal propria and submucosa from DJT-treated mice, a numerical decrease of COX-2, IL-2R-, ICMA-1 positive cells was observed. 5. The distribution of apoptotic cells in epithelium and lamina propria from UCE mice: a noticeable increase of apoptotic cells in region of hemorrhagic erosion was seen, but in the distribution of apoptotic cells in epithelium and lamina propria from DJT-treated mice, a remarkable decrease of apoptotic cells was seen. Conclusions: According to the above results, Dojeckjiyu-tang has a moderate effect on ulcerative colitis in descending colon.

  • Background: Colorectal cancer is the third most common type of cancer in males and the second in females in Iran. Males are more likely to develop CRC than women and age is considered as a main risk factor for colorectal cancer. Prevalence of colorectal cancer has been increasing in Asian countries. Aim: The object of this study was to determine the clinical and pathology characteristics of colorectal polyps in Iranian patients and to investigate the variation between our populations with other populations. Materials and Methods: A total of 167 patients with colorectal polyps were included in our study. All underwent colonoscopy during 2009-2013 and specimens were taken through polypectomy and transferred to pathology. All data in patient files including pathology reports were collected and analyzed by SPSS 16 software. A two-tailed test was used and a P-value of < 0.05 was considered significant. Results: Mean age of participants was $57{\pm}15$. Some 84 were females (50.3%) and 83 males (49.7%). Total of 225 polyps were detected which 119 (52.9%) were in males and 106 (47.1%) were in females. Solitary polyps were observed in 124 patients (74%), 26 (15.6%) had two polyps and 17 (10.1%) with more than two polyps (three to five). Rectosigmoid was the site of most of the polyps (63.1%), followed by 19.6% in the descending colon, 7.6% in the transverse, 5.8% in the ascending, and 3.1% in the cecum, data being missing in two cases. Conclusions: Recto sigmoid was site of most of the polyps. The most prevalent type of lesion was adenomatous polyps detected in 78 (34.7%). Mixed hyperplastic adenomatous type observed in 70 (31.1%). This high prevalence of adenomatous polyps in Iranian patients implies the urgent need for screening plans to prevent further healthcare problems with colorectal cancer in the Iranian population.

  • A 64-year-old female with glioblastoma multiforme (GBM) was assigned to our department for whole body PET/CT scan. She ingested 1 liter of pure water as negative oral contrast just before PET/CT examination. FDG-PET/CT images showed a very intense hypermetabolic, focal lesion in the abdominal cavity around descending colon. The SUVmax of the lesion was 17.2. But there was no abnormal lesion corresponded to the area of PET scan in the combined contrast enhanced CT scan. We suggested considering a malignant lesion due to very intense glycolytic activity. Conventional abdominal CT scan & colonoscopy were accomplished within one week after PET/CT evaluation. There was no abnormality in both examinations. We executed follow-up PET/CT evaluation after 1 month and couldn't find any abnormality around the corresponding area. So we concluded the hypermetabolism was colonic physiologic uptake. A colonic physiologic uptake is a well known cause of false positive finding. Nuclear physicians should be considered the possibility of malignancy when interpret focal colonic uptake, especially incidental finding. There are a few reports that using of negative oral contrast is able to reduce gastrointestinal physiologic uptakes. But as we can see in this case, although we used negative oral contrast, intense physiologic uptake is detected and maxSUV is able to up to 17.2. So, it is important to keep a fact in mind. Even though there is a colonic physiologic uptake in PET/CT image, it may be able to show very intense hypermetabolism regardless of using negative oral contrast.

  • An 11-year-old spayed female maltese was presented for abdominal distention, dysuria and dyschezia. Panting and heart murmur was found and abdominal palpation was difficult due to increased abdominal pressure. A soft tissue mass, $6{\times}3cm$ in size, was identified radiographically in pelvic canal, displacing the descending colon to the medioventral direction and the urinary bladder cranially. On ultrasonography, the mass consisted of homogeneous hypoechoic parenchyma containing the focal hyperechoic region ($1.6{\times}1.5cm$). The mass had distinct margin and no connection with adjacent organs. It was considered as a mass originating from the retroperitoneal cavity. Additional diagnostic procedures were not advanced because of the owner's request, and only a surgical excision of the mass was performed to alleviate the dysuria and dyschezia. Histopathologic examination and immunohistochemistry determined the mass as a soft tissue sarcoma and excluded hemangiosarcoma and osteosarcoma, both are the most common types of the retroperitoneal tumors. This report described non-vascular soft tissue sarcoma originating from the retroperitoneal cavity in a maltese dog.
