Excessive administration of phenylbutazone was associated with development of right dorsal ulcerative colitis. The clinical signs of right dorsal colitis include chronic colic and weight loss. The laboratory abnormalities include panhypoproteinemia and a high WBC count in the abdominal fluid. Medical management of the chronic colic and protein-losing enteropathy associated with the ulcerative lesions in the right dorsal colon and surgical bypass of the right dorsal colon did not result in long-term resolution of clinical signs. Resection of the ulcerated right dorsal colon through a right lateral approach at the 16th rib resulted in resolution of intestinal protein loss and colic. The results of this case suggest that surgical resection of the ulcerated right dorsal colon may be the recommended treatment for right dorsal ulcerative colitis.  相似文献

Two Boxer dogs with histologically confirmed histiocytic ulcerative colitis were treated with enrofloxacin, one as sole therapy and one in conjunction with prednisolone, after failure of standard therapy. Clinical remission occurred rapidly in both dogs after commencement of enrofloxacin and in one case where repeat colonoscopy was performed the endoscopic appearance of the mucosa was normal within 2 weeks. Histological examination of the colonic mucosa in this dog after 7 months showed resolution of the cellular infiltration characteristic of histiocytic ulcerative colitis. Histological improvement following therapy in Boxer dogs with histiocytic ulcerative colitis has not been reported previously.  相似文献

Colonic and rectal forceps and excision biopsies of 355 dogs with clinical signs of large bowel disease were investigated. Five percent of the forceps biopsies were unsuitable for examination; all excision biopsies were of good quality. Forceps biopsies were obtained from one to eight sites, up to 60 cm cranial from the anus, while excision biopsies, mostly from tumors, were from the rectoanal region. Slight to severe colitis and/or proctitis was found in 192 dogs (54%). A single type of colitis was seen in 160 dogs; in 53 cases the lesions were local, in 107 cases multiple. A combination of different types of colitis was found in 32 dogs. Atrophic colitis, diffuse colitis and canine histiocytic ulcerative colitis were the most prominent findings, followed by ulcerative, superficial and eosinophilic colitis. Follicular, hypertrophic and aspecific granulomatous colitis were found in only a few cases. Tumors were diagnosed in 57 dogs (16%). Of these tumors 50 were of epithelial and seven were of mesenchymal origin. A high percentage (61%) of the epithelial tumors consisted of adenomas of the rectoanal region. In ten other dogs (3%) a differential diagnosis of lymphosarcoma or colitis had to be made. Colitis and colorectal tumors were more prevalent in Boxers, German Shepherds, Poodles, Great Danes and Spaniels. In the Boxers simple chronic colitis, as well as canine histiocytic ulcerative colitis were more frequently found, the latter especially in females. Other biopsy findings were edema, crypt cysts, hemorrhages, an increased number of intraepithelial lymphocytes and an increased or decreased number of goblet cells.  相似文献

The application of 99mTc-HMPAO labeled white blood cells to support the diagnosis of right dorsal ulcerative colitis was studied in two horses with a history and clinical signs consistent with phenylbutazone toxicity. These images were compared to a reference horse unaffected by right dorsal ulcerative colitis. Blood was collected aseptically in heparinized syringes from the patients for in vitro white blood cell (WBC) radiolabeling. The buffy coat was separated out and radiolabeled with 99mTc-HMPAO. The radiolabeled blood was re-injected i.v. and four images of the right and left side of the patient's abdomen were acquired at 4 hours and 20 hours post-injection. Results of the nuclear study revealed no abnormal findings in the abdomen at the four-hour post-injection images in any horse. Images obtained 20 hours post-injection revealed a linear uptake of radiolabeled WBCs in the right cranioventral abdomen in the region of the right dorsal colon in both horses with right dorsal ulcerative colitis. The reference horse had no radiopharmaceutical uptake in this region. This nuclear imaging study was a rapid, non-invasive method to identify right dorsal colon inflammation. These findings not only supported the diagnosis of right dorsal ulcerative colitis, but also facilitated appropriate medical management of each horse.  相似文献

Moderate to severe ulcerative colitis of the right dorsal colon was diagnosed by necropsy or by exploratory celiotomy and biopsy in 13 horses with a primary clinical complaint of either colic, diarrhea, or weight loss. Clinical signs varied from acute fulminating diarrhea (possibly with fever), colic, dehydration, endotoxic shock and death, to a chronic condition manifested by mild intermittent colic up to several months in duration, and weight loss with or without mild diarrhea. In a large percentage of the horses, those affected had been hypovolemic and received nonsteroidal anti-inflammatory drugs (NSAID) or had received inappropriately high doses of phenylbutazone before the onset of illness. Experimental treatment of two horses with high doses of a phenylbutazone oral paste preparation (6 gm once daily for 5 days) and limitation of their water intake to approximately one half of maintenance requirement (for 5 days) resulted in reproduction of ulcerative colitis involving only the right dorsal colon, which was apparent at necropsy examination 11 and 15 days after initiation of drug use. It was concluded that localized ulcerative lesions in the right dorsal colon may be a previously unreported manifestation of toxicity due to the administration of NSAID.  相似文献

Histiocytic ulcerative colitis (HUC) is described in three non-boxer dogs. Clinical signs were typical of large-bowel diarrhea and included soft stool, hematochezia, tenesmus, and an increased frequency of defecation. Diagnosis in each case was made by light microscopic evaluation of endoscopically obtained colonic biopsy specimens. Treatment regimes varied, but included immunosuppressive agents, anti-inflammatory drugs, antimicrobials, and dietary modification. Clinical response was substantial in two patients, while the third patient was euthanized due to treatment failure. The authors' observations indicate that HUC may be encountered in non-boxer dogs.  相似文献

A 3-year-old Quarter Horse gelding was evaluated for chronic weight loss, diarrhea, and pruritus. Physical examination revealed several ulcerative lesions on the skin and mucosal membranes. Diagnostic imaging findings were consistent with enteritis, typhlitis, and colitis. Multisystemic eosinophilic epitheliotropic disease (MEED) was diagnosed upon necropsy. This disease may be considered a form of equine inflammatory bowel disease complex which can be challenging to diagnose, requiring histological assessment, and in some cases, the use of immunohistochemical markers.Key clinical message:Multisystemic eosinophilic epitheliotropic disease is challenging to diagnose but should be considered in horses with chronic weight loss that fail to respond to conventional treatment for concurrent diarrhea and skin lesions.  相似文献

The experiment was aimed to establish mouse model of ulcerative colitis(uc) by screening the optimum concentration of dextran sulfate sodium salt(DSS).Thirty BALB/c mice were randomly assigned to control group, 3.5% DSS group and 5% DSS group, ten mice each group.Mice drank water freely for 5 days, the body weights of everyday were recorded, stool was observed and stool occult blood was tested.After the experiment, the changes of TNF-α, MPO, MDA and GSH were tested, and the colon weight/length ratio was calculated.Compared with control group, the activity of MPO and content of MDA in the experiment groups were significantly increased(P<0.05), and content of GSH was significantly decreased(P<0.05).3.5% and 5% DSS both could successfully establish mouse model of ulcerative colitis.Mice in 5% DSS group had poor mental state, such as lethargy, malaise;Mice in 3.5% DSS group were appropriate, the mice mental was good, MPO, MDA and GSH were significantly different compared with control group(P<0.05), but there were no difference compared with 5% DSS group(P>0.05).So 3.5% DSS was more appropriate than 5% DSS to establish mouse model of ulcerative colitis.  相似文献

本试验旨在通过筛选葡聚糖硫酸钠盐(DSS)最佳浓度建立小鼠溃疡性结肠炎模型。将30只BALB/c小鼠随机分为对照组、3.5% DSS组、5% DSS组,每组10只。小鼠自由饮水5 d,每天记录小鼠体重,观察粪便性状,测便潜血。试验结束后测血清TNF-α、结肠组织髓过氧化物酶(MPO)、丙二醛(MDA)、还原性谷胱甘肽(GSH)活性变化等指标,计算结肠重量/长度比值。与对照组相比,两试验组结肠组织中MPO活性显著升高(P<0.05),MDA含量显著升高(P<0.05),GSH含量显著降低(P<0.05)。结果表明,两种浓度葡聚糖硫酸钠盐均可造模成功,5% DSS组小鼠精神状态很差,表现嗜睡、萎靡状态,而3.5% DSS组小鼠精神状态良好,且组织中MPO、MDA、GSH与对照组相比均差异显著(P<0.05),与5% DSS组相比差异不显著(P>0.05),因此,选用浓度为3.5% DSS造模更合适。  相似文献

A case of histiocytic ulcerative colitis (granulomatous colitis) in a one–year–old female French Bulldog is described. Until now this disease has been described only in the Boxer breed.
The dog had an increased frequency of defaecation and the faeces contained blood and mucus. Colonoscopy showed some irregularities and a few haemorrhages in the mucosa of the caudal part of the colon. At a distance of approximately 25 cm from the anus there was a stricture caused by rigidity of the colon wall. Radiographic examination revealed marked shortening of the colon. There was also narrowing of the midpoint of the descending colon in some radiographs, but the colon appeared to be fully distensible when filled with barium. Histologically, periodic acid–Schiff (PAS)–positive staining histiocytes were found in biopsy and autopsy specimens from the colon.  相似文献

A 1.5-year-old captive female Dama wallaby (Macropus eugenii) died after a 3-month period of progressive weight loss, anorexia, bloat, and diarrhea. Histopathologic examination revealed numerous Entamoeba histolytica trophozoites within the gastric mucosa and, less frequently, gastric submucosa and submucosal vessels. Immunofluorescent antibody testing confirmed the identity of the trophozoites as E. histolytica. The trophozoites were associated with mild glandular epithelial necrosis, mucosal erosions, and lymphoplasmacytic inflammation. E. histolytica most commonly causes necrotizing and ulcerative colitis in humans and captive nonhuman primates, and it causes necrotizing and ulcerative gastritis in nonhuman primates with sacculated stomachs adapted for leaf fermentation. Rare cases of gastric amebiasis also have been been reported in captive macropods, which also have complex sacculated stomachs. To our knowledge, this is the first report confirming E. histolytica as the cause of gastric amebiasis in a wallaby. The zoonotic potential of this infection in macropods is uncertain.  相似文献

HISTIOCYTIC ULCERATIVE COLITIS IN A BOXER DOG   总被引：1，自引：0，他引：1  
SUMMARY: A 2-year-old male Boxer dog had passed loose faeces mixed with fresh blood and mucus for 8 months. Tenesmus after defaecation was a feature. Colitis was diagnosed from the proctoscopic appearance of the recto-colonic mucosa and confirmed from a biopsy. The disorder proved unresponsive to sulphasalazine therapy, but oral chloramphenicol, betamethasone and prednisolone enemas administered over a 6-week period produced a satisfactory clinical improvement, which persisted for a further 3 weeks without treatment. However, follow-up proctoscopy showed only a marginal improvement in the appearance of the mucosa and appeared to exacerbate further bloody diarrhoea, which persisted. The dog was destroyed and histiocytic ulcerative colitis confirmed at autopsy.  相似文献

An 11‐month‐old female entire West Highland White Terrier presented for chronic diarrhea with acute deterioration in demeanor and progression to systemic inflammatory response syndrome. Transcutaneous abdominal ultrasonography identified colonic ulceration and secondary mucosal gas. Suspected hepatic portal vein gas and hepatic parenchyma gas were also visualized. The patient was stabilized and managed for ulcerative colitis. Based on endoscopic biopsies, the dog was diagnosed with severe, chronic, pyogranulomatous colitis. On repeat ultrasonographic evaluation the portal vein and hepatic gas had resolved but the patient deteriorated and was ultimately euthanized due to sepsis.  相似文献

A 9-month-old French bulldog was referred for signs of chronic large bowel diarrhea. The dog had an increased frequency of defecation, tenesmus and hematochezia. Flexible colonoscopy showed hyperemia, irregularities and ulcerations with multifocal hemorrhages in the mucosa from the descending colon to the proximal rectum. Multiple colonic biopsies were characterized by infiltrations of PAS positive histiocytes in the lamina propria. A diagnosis of histiocytic ulcerative colitis (HUC) was made, and the animal showed only minimal improvement, although it was treated with nutritional and medical therapies. This is the second case of HUC in French bulldog, a breed which has ancestral relations to Boxer dogs.  相似文献

Three horses with colic, clinical evidence of endotoxaemia and high serum activities of creatine kinase and aspartate aminotransferase were examined postmortem. The horses were diagnosed with severe ulcerative colitis, pyloric ulceration and stenosis with colonic sand impaction, and colonic obstruction due to faecaliths. There was no gross or histological evidence of muscle trauma. Their semimembranosus muscles had scattered acute to subacute segmental necrosis of the myofibres, suggestive of endotoxin-induced muscle injury.  相似文献
