Abstract
The aim of this experiment was to investigate the effects of Ageratina adenophora on the expression of epithelium tight junction proteins and inflammatory factors in the rumen of goats. Twelve goats were randomly divided into three groups. The first group was the blank control group (n = 3, C) which was fed normal diet. The second group was fistulas control group (n = 3, RFC), which was fitted with rumen fistulas, and fed normal diet. The third group was the A. adenophora test group (n = 6, AA), which was fitted with rumen fistulas and fed a mixture of 60% of normal diet and 40% of A. adenophora grass powder. The feeding experiment lasted for 90 d, after which all goats were sacrificed and samples were collected from the rumen dorsal sac and ventral sac. The relative expression of mRNA of inflammatory factors in the rumen epithelium (tumor necrosis factor alpha [TNF-α], interferon gamma [IFN-γ], interleukin 1 beta [IL-1β], IL-2, IL-4, IL-6, and IL-10) and tight junction protein genes (occludin, claudin-1, and ZO-1) was measured by quantitative real-time fluorescence PCR. Expression of tight junction proteins in the rumen epithelium was measured by Western blot. A correlation was established between the expression of inflammatory factors and tight junction protein genes using Graph Pad Prism. The results showed that A. adenophora caused a significant increase in the mRNA expression levels of TNF-α, IFN-γ, IL-1β, IL-2, IL-6, and IL-10 in the rumen epithelial (P < 0.05 or P < 0.01). The expression of tight junction proteins at both gene and protein levels was significantly decreased (P < 0.05 or P < 0.01). Furthermore, the correlation analysis revealed that the changes in tight junction protein expression in the test group were closely related to the upregulation of the expression of inflammatory factors TNF-α and IFN-γ in rumen epithelial cells. In conclusion, the expression of inflammatory factors was increased and the expression of tight junction proteins was decreased in goats after feeding on A. adenophora, which caused some damage to the rumen epithelium.

Abstract
Cleft palate is the most common congenital orofacial defect in dogs. Although this topic has been extensively studied in experimental dogs, current literature on clinical patients is limited to case reports and small case series studies with many individual opinions based on experience. This narrative review summarizes the literature of the last 10 years with application to clinical practice, focusing on the preparation of the patient until surgery, options for surgical management, and perioperative complications. Surgical treatment must be performed to obtain separation between the nasal/nasopharyngeal and oral/oropharyngeal passages. This will allow the dog to have independent function and reduce clinical signs associated with food, water, and other foreign material entering the respiratory tract. Surgical treatment has good to excellent outcomes when the procedure is carefully planned and appropriately executed despite the high rates of postoperative oronasal fistula reported.

Abstract
AIM This study aimed to describe the diagnosis and treatment of various surgical salivary affections in buffaloes. MATERIALS AND METHODS This study included 135 buffaloes examined at Dakahlia Governorate between 2011 and 2022 suffering from various surgical salivary affections. The recorded surgical affections had salivary fistula (n = 44), ectasia of Stenson's duct (n = 11), ranula/mucocele (n = 46), and cervical sialocele (n = 34). The buffaloes were sedated using an intramuscular injection of xylazine (0.05 mg/kg) and local infiltration analgesia of lidocaine for specific surgical interventions. RESULTS The salivary duct fistula cases were surgically corrected using a retrograde infusion of povidone-iodine into the duct and its double ligation with Prolene following fistulectomy. Intraoral marsupialization was done in buffaloes suffering from ectasia of the parotid duct. The mucocele /ranula was surgically incised with daily flushing with povidone-iodine. The cervical sialocele was treated by giving an elliptical excision on the sialocele, and sialoadenectomy of the mandibular salivary gland was performed to facilitate dynamic fluid/saliva drainage. A 92.5% of diseased buffaloes showed an uneventful recovery without any postoperative complications after the first treatment, whereas 7.5% of animals tended to recur. The most common and almost equally distributed salivary affections recorded in adult buffaloes were parotid duct fistula, mucocele, and cervical sialocele. The Stenson's duct ectasia was commonly registered in calves, being congenital. CONCLUSION Ranula was the most common salivary affection encountered in adult buffaloes, closely followed by parotid duct fistulae and cervical sialoceles. Stenson's duct ectasia was the least encountered salivary affection in calves and was congenital. All salivary affections were corrected easily and safely, with satisfactory outcomes.

Abstract
CASE DESCRIPTION A 12-year-old Friesian stallion was examined because of a 1-year history of preputial injury and urination through a urethrocutaneous fistula located at the midbody of the ventral aspect of the penis. CLINICAL FINDINGS Physical examination revealed an opening with a clearly apparent mucocutaneous junction 12 cm from the distal opening of the urethra on the ventral left side of the penis. Endoscopic examination of the distal portion of the urethra confirmed a blind pouch with no communication with the fistula or proximal portion of the urethra. TREATMENT AND OUTCOME A temporary perineal urethrostomy was performed with sedation and local anesthesia, with the stallion standing, to divert urine from the urethral reconstruction site. Fistulectomy and urethral resection and anastomosis were performed under general anesthesia with the stallion in dorsal recumbency. At 15 days after surgery, endoscopic examination of the urethra revealed distortion of the urethral lumen at the fistulectomy site. Under sedation, the urethra was dilated for 5 minutes every 12 hours for 3 days. At 22 days after surgery, endoscopic examination of the urethra revealed a healed anastomosis site and a large urethral luminal diameter. At 36 months after surgery, the owner reported that the stallion had normal micturition and had sired multiple foals by live cover matings. CLINICAL RELEVANCE Severe preputial or penile trauma in horses is most commonly treated with amputation because of concerns of postoperative urethral stricture and occlusion. To the authors' knowledge, this case represented the first time that a successful end-to-end anastomosis of the distal portion of the urethra has been performed in a stallion.

Abstract
CASE DESCRIPTION A 9-year-old pony gelding was evaluated because it was suspected that a persistent oronasal fistula had developed after a fractured right maxillary second premolar tooth had been extracted via repulsion 6 months earlier. CLINICAL FINDINGS Unilateral mucopurulent nasal discharge and malodorous breath were noted on clinical examination. Examination of the oral cavity revealed a 1 × 0.5-cm defect at the oral aspect of the right maxillary second premolar alveolus, from which feed material was extracted. Endoscopic examination revealed feed material in the rostral aspect of the right nasal cavity, confirming the diagnosis of oronasal fistula. TREATMENT AND OUTCOME The pony initially underwent a reconstructive surgical procedure that combined an alveolar bone flap with a sliding mucoperiosteal hard palate flap to repair the oronasal fistula. The fistula reoccurred 5 months later and was ultimately repaired by means of a novel 2-layer flap closure method involving an autogenous fascia lata graft and oral mucosa flap. CLINICAL RELEVANCE Fascia lata was effective as a scaffolding graft for repair of the oronasal fistula in this pony and may be useful for repair of oronasal fistulas in other equids as well.

Abstract
Management of a traumatic oronasal fistula with a prosthetic device in an 8-year-old male neutered domestic shorthair cat is described. The animal had fallen from a height of three stories at the age of 1 year. The fall had resulted in a fracture of the hard palate and a split in the palatal mucosa. Two surgical attempts to close the defect had been unsuccessful and an autopolymerizable acrylic resin prosthesis had produced unsatisfactory results. The management of the chronic traumatic fistula with a conical prosthetic device was fast, easy and efficient. The device was removed and a second one was put in place after 2 years. This method would appear particularly useful for obturation of large palatal defects that have failed to heal after attempts at surgical closure and is an alternative treatment for debilitated cats which may not be candidates for longer surgical procedures.

Abstract
BACKGROUND The diagnosis of post-traumatic spinal cerebrospinal fluid (CSF) fistulae due to dural tears or lesions remains a challenge. Thus far, CT myelography is the standard test used to diagnose these complications. PURPOSE To evaluate the diagnostic ability of gadolinium-enhanced MR cisternography/myelography (intrathecal gadopentate dimeglumine or Gd-DTPA) in small animals that had experienced accidental spinal trauma. MATERIAL AND METHODS Four dogs and one cat suffered traumatic accidents resulting in neurological deficits underwent spinal MRI with intrathecal Gd-DTPA after routine plain films and MR images. RESULTS T2-weighted SE images showed high water content in the epidural space or in the surroundings of the vertebrae in four animals. MR myelography revealed CSF leakage in all of them. In two animals CSF leaks were observed exuding from the spinal canal and tracking towards adjacent loose fat and interfascial planes. In two other animals Gd-DTPA extravasation was diffusely collected in paraspinal tissues around the vertebral arch. In the fifth animal a focal pseudomeningocele was observed adjacent to the traumatized region. CONCLUSION Intrathecal administration of Gd-DTPA is an effective method to reveal and confirm post-traumatic spinal CSF fistulae or other dural lesions in animals with potential application in humans.

Abstract
Chronic facial defects extending into the sinuses of two mares were repaired using periosteal flaps. Partial osseous bridging was established over the defects following repair. Previous attempts to close the defects with skin alone had failed. A periosteal flap is a simple surgical technique that provides the foundations for successful repair, despite the chronicity of some fistulae.

Abstract
Arterioportal fistulae are rare congenital anomalies of the hepatic vasculature. Diagnosis is conventionally made by selective angiography or ultrasonography. This report describes use of a dual-phase computed tomographic (CT) angiographic technique to diagnose arterioportal fistulae in four dogs. Advantages of this method include a noninvasive peripheral injection of contrast medium, ability to diagnose multiple acquired extrahepatic shunts, and observation of hemodynamic changes such as hepatofugal blood flow and reduced circulation to the caudal abdomen. The hepatic vasculature including arteries, veins, and portal veins can be completely evaluated. Dual-phase CT angiography is a safe and minimally invasive method of diagnosing arterioportal fistulae in dogs.

Abstract
OBJECTIVES To develop a reliable method for measurement of cyanide concentrations in cattle, using gas chromatography-mass spectrometry (GC-MS), and establish reference ranges of cyanide concentrations in cattle. ANIMALS 52 Fleckvieh cattle. PROCEDURE Cattle were allocated to 3 groups; 12 were fed leguminous grass and hay, 36 were fed whole-maize and corn-cob silages, and 4 were fed other feedstuffs. Samples of blood, rumen fluid, and liver were collected at time of slaughter. Serum, rumen fluid, and liver homogenate were assayed for cyanide content, using a derivatization procedure. A technique for analysis by GC-MS that used selected ion monitoring was developed. RESULTS Compared with a spectrophotometric method, detection of cyanide in serum and rumen fluid by use of GC-MS was selective and sensitive, with a limit of detection of 0.7 microM. Spectrophotometric analysis yielded false-negative and false-positive results. Thus, the GC-MS method was used for subsequent analysis. In all cattle except 1, cyanide concentration ranged from < 0.7 to 35 microM in serum and from < 0.7 to 28 microM in rumen fluid; cyanide concentration in that 1 animal was 206 microM. Cattle fed clover, grass, grass hay, and clover hay had 8.3- to 8.6-fold higher mean cyanide concentrations in rumen fluid and serum than cattle fed whole-maize and corn-cob silages. CONCLUSIONS AND CLINICAL RELEVANCE Results of this study suggest a reference range that should be useful for aiding in the diagnosis of cyanide poisoning. Also, cattle can apparently accommodate a serum cyanide concentration of 206 microM without adverse effects.

Abstract
A one-year-old, intact male, 28-kg, mixed-breed dog developed neurological episodes consistent with emboli. An acquired III/VI holosystolic heart murmur was ausculted in the mitral area, and valvular endocarditis with pulmonic and aortic insufficiency were noted at echocardiographic examination. An abnormal communication (i.e., fistula) between the left ventricular outflow tract (LVOT) and the left atrium adjacent to the mitral valve annulus was noted with Doppler imaging and confirmed with angiography. Infective valvular endocarditis was confirmed based on two of three blood cultures being positive for Staphylococcus intermedius. In humans, a sequela to infective endocarditis of the aortic or mitral valve, or both, is rupture of the mitral-aortic intervalvular fibrosa, resulting in a communication between the LVOT and the left atrium. This is the first report of this sequela in the dog.

Abstract
This report describes the history, clinical, electrocardiographic and echocardiographic findings, treatment, outcome and post-mortem findings in seven horses with aorto-cardiac fistula. Affected horses included 5 stallions, one gelding and one mare; 2 each of the Thoroughbred, Arabian and Standardbred breeds and one Thoroughbred-cross with a mean +/- s.d. age of 12 +/- 4 years, range 6-18 years. The presenting signs were acute distress (four horses), exercise intolerance (two horses) and the lesion was detected during a routine examination in one horse. Five horses had monomorphic ventricular tachycardia on admission and one other had a history of this arrhythmia. Five horses had a characteristic continuous murmur loudest in the right fourth intercostal space. Echocardiography (six horses) and/or post-mortem examination (four horses) revealed the horses had aorto-cardiac fistulas arising from the right aortic sinus in all five horses in which the site was recorded. Two horses had ruptured aneurysmal dilatations of the aortic wall at this site. Fistulas extended into the right ventricle in four horses; the right atrium in two horses, the left ventricle in one horse, and five horses had dissecting tracts in the septal myocardium. Horses survived for periods ranging from 24 h to 4 years. Aorto-cardiac fistula should be considered in the differential diagnosis for horses presenting with acute distress, bounding arterial pulse, a right-sided continuous murmur and/or monomorphic ventricular tachycardia, particularly in middle-aged or older stallions. Echocardiography is the technique of choice for confirming the diagnosis and demonstrating accompanying cardiac changes.

Abstract
A portosystemic shunt (PSS) is a well-recognized condition causing signs of hepatic disease in young cats. The condition consists of an aberrant vascular communication between the portal and systemic vascular systems. Although medical management can palliate the clinical signs of hepatic disease in these cats, definitive treatment consists of surgical attenuation of the shunting vessel. Surgical treatment is limited in some cats by access to the shunting vessel and in others by creation of portal hypertension if the vessel is completely occluded. The long-term prognosis is good in cats in which the PSS can be completely ligated. Clinical improvement is seen initially in cats in which only partial ligation can be accomplished, but recurrence of clinical signs is common.

Abstract
A lateral approach was used successfully in seven of 10 dogs to resolve fistulas which developed after total ear canal ablations and bulla osteotomies. The approach facilitated identification and removal of horizontal ear canal remnants in four of the 10 cases. Facial nerve function was worsened temporarily by lateral exploration in two cases. Seven cases had no fistula recurrence during follow-up, which ranged from 12 to 72 months. Three cases each had fistula recurrence one-to-two months after fistula exploration.

Abstract
Twenty-seven German shepherd dogs with perianal fistulas and histological evidence of colitis were entered in a prospective clinical study to investigate the association between perianal fistula and colitis. Additionally, the response of perianal fistula disease to immunosuppressive doses of prednisone and an alternative protein diet was evaluated. All 27 cases completed the treatment protocol, and perianal fistulas completely resolved in nine (33.3%) cases, improved in nine cases, and remained unchanged in nine cases.

Abstract
A 4.5-month-old Himalayan cat was evaluated because of a cleft secondary palate. Multiple surgical procedures failed to provide soft-tissue coverage of the defect. A 3-cm silastic nasal septal button was trimmed and placed in the oronasal fistula. This prosthodontic appliance provided obturation of the defect without the need for removal or cleaning. Food accumulation between the appliance and oral mucosa was minimal, avoiding the need for appliance manipulation. The owner reported clinical signs related to oronasal fistula or appliance complications were not evident 12 months after placement.

Abstract
A method was developed to surgically implant a silicone/stainless steel fistula-cannula in the cecum of freely moving rats. The specially designed fistula-cannula allows sampling of cecal contents at any time without disturbing the physiologic functions of the intestinal tract, as evaluated by observation of general well-being and postmortem macroscopic inspection. The fistula-cannula was implanted in 12 male rats under general anesthesia. The animals remained in good health during the postoperative period lasting up to 9 weeks. They gained weight normally compared with a control group (n = 8) that had not undergone surgery. Samples of 0.2 to 1.0 g of contents could be collected with a microspatula, without the need to anesthetize the animal. The model provides a useful system for sampling cecal contents without the need to sacrifice the animal. Because it allows cross-over studies to be carried out, this approach may result in significantly reducing the number of animals required for digestive studies.

Abstract
Microcytosis is a common laboratory finding in dogs with congenital portosystemic shunt (PSS), although its pathogenesis is not yet understood. Because the most common cause of microcytosis in dogs is absolute or relative iron deficiency, iron status was evaluated in 12 young dogs with PSS. Complete blood counting was done before surgical correction in all dogs, and in 5 dogs after surgery, by use of an automated hematology analyzer. Serum iron concentration and total iron-binding capacity (TIBC) were determined coulometrically, and percentage of transferrin saturation was calculated. Erythrocyte protoporphyrin content was quantified by use of front-face fluorometry. Serum ferritin concentration was measured by use of ELISA. Serum ceruloplasmin content was determined colorimetrically (with p-phenylenediamine dihydrochloride as substrate) as an indirect indicator of subclinical inflammation, which may result in impaired iron utilization. Special stains were applied to liver (10 dogs; Gomori's) and bone marrow aspiration biopsy (7 dogs; Prussian blue) specimens for qualitative assessment of tissue iron content. Nonpaired Student's t-tests were used to compare serum iron concentration, TIBC, percentage of transferrin saturation, and erythrocyte protoporphyrin, ferritin, and ceruloplasmin concentrations in dogs with PSS with those in clinically normal dogs. All dogs had microcytosis before surgery; microcytosis resolved in 3 dogs after surgical correction. Serum iron concentration and TIBC were significantly lower in PSS-affected dogs than in clinically normal dogs. Erythrocyte protoporphyrin, ferritin, and ceruloplasmin concentrations in PSS-affected dogs were not significantly different from those in health dogs.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In the last five years 55 cases of orbital space-occupying lesions in dogs and cats were treated at the Veterinary Surgical Clinic of the University of Zurich. The most frequent diagnosis was orbital neoplasia (n = 29), followed by orbital abscesses or cellulitis (n = 17). Orbital hematoma (n = 5), salivary mucocele (n = 3), A/V-fistulas (n = 1), and eosinophilic myositis (n = 1) appear to be less frequent entities. The 55 cases comprised 42 dogs and only 13 cats, which seem to be less likely to suffer from orbital disease. This difference was particularly obvious in orbital inflammatory disease. The most important clinical sign is exophthalmos. Other symptoms are listed in tables. Special emphasis is put on the diagnostic work-up of orbital space-occupying lesions. An algorithm shall guide the practitioner to the correct diagnosis. The management of orbital disease is only briefly mentioned but will be the topic of a future article.

Abstract
The pig is probably one of the best mammalian models for studying the digestive functions and the biliary excretion of drugs because of the tight similarities with humans. Insertion of a T drain in the common bile duct after cholecystectomy in humans became uncommon because of surgical progress. For this reason, we developed a model using a bidirectional cannula to study the biliary secretion in the conscious Micropig Yucatan. We used this breed because of their ready availability and low stable weight. The surgical procedure was a double choledococholedocal fistula with a bypass on the main biliary duct, maintaining the continuous flow of bile into the duodenum through the sphincter of Oddi. This fistula remained effective for at least sixty days with normal hepatic biologic parameters. The development of our model could improve the biliary excretion study of drugs. Comparison of different routes of administration and interaction pharmacokinetic studies could also be studied in the same micropig, eliminating intersubject variations.

Abstract
The signalment, history, clinical signs, radiographic findings, and surgical findings of 25 consecutive animals that had sinography were reviewed to assess the contribution made by sinography to diagnosing and surgically managing draining tracts in small animals. There were 23 dogs and 2 cats; a variety of breeds and both sexes were represented (18 males, 7 females). Before referral the mean duration of clinical signs was 9.8 months (range, 0.5 to 33 months) and a mean of 2.0 surgical procedures (range, 1 to 5) had been performed. Sinuses occurred in a variety of locations, most commonly the neck (10), head (6), and paws (5). The most common cause was foreign body (15). Survey radiographs showed abnormalities in 21 of 26 (78%) instances, including soft-tissue swelling (11), chronic-appearing periosteal reaction on adjacent bones (5), possible foreign body (4), and gas in soft tissues (2). Sinography (or fistulography) enabled definite diagnosis of the cause of the sinus (or fistula) in 15 of 26 (58%) instances and demonstrated 13 of 15 foreign bodies (sensitivity 87%; specificity 100%). Tracts caused by an esophageal perforation and otitis media were also correctly shown by fistulography. In 11 animals, sinography indicated that the position or extent of the lesion was different to that expected on the basis of clinical signs and survey radiographs.

Abstract
Focal metatarsal fistulas were identified in 5 young adult German Shepherd Dogs or dogs of similar breeding. A specific cause was not identified when biopsy specimens for culture and histologic examination were evaluated. Corticosteroid treatment was beneficial for some lesions. The dogs did not have other dermatologic diseases, and the clinical course, although chronic, was generally benign.

Abstract
An eight-year-old Highland pony which had previously shown normal laryngeal function, underwent general anaesthesia for surgical treatment of a mandibular sinus. During its recovery from the anaesthesia, the pony suffered great respiratory distress and stridor, due to total bilateral laryngeal paralysis and pulmonary oedema. The animal was immediately given a temporary tracheostomy. Some hours later, postoperative myositis developed; it resolved within two days and the pony's laryngeal function returned to normal during the following year.

Abstract
Nylon cable bands used as ligatures caused postsurgical complications in 5 ovariohysterectomized bitches. Clinical signs included fever, stiffness, strangury, draining fistulae, vaginal discharge, and tenesmus. Most signs first appeared several years after surgery, and all signs were resolved after removal of the bands. On the basis of our experience, we suggest that nylon cable bands not be used for ovariohysterectomy ligations.

Abstract
Arthrography, tenography, and fistulography (or sinography) can provide additional information about the soft-tissue components of joints, tendon sheaths, and draining tracts, respectively. Arthrography is a valuable aid in the diagnosis of synovial masses, such as villonodular synovitis, and osteochondrosis. Tenography is particularly useful in evaluating chronic tendon sheath distention. Fistulography is an effective means of identifying acute traumatic damage to synovial structures and determining the cause and extent of draining tracts.

Abstract
An uncommon neoplasm of the larynx, rhabdomyosarcoma, was diagnosed in a 6-year-old 14-kg neutered female Spitz. In addition to the progressive onset of expected clinical signs of the tumor (exercise intolerance, respiratory stridor, inability to bark), the dog experienced hyperthermic crisis. Laryngectomy was successful in eradicating the local neoplastic tissue; however, unusual postoperative complications developed and included acute complications of pharyngotracheal fistula and hypoparathyroidism, and long-term complications of periodic collapse of the tracheal stoma and intolerance to heat. Probable causes and successful management of these complications are described. At 22 months after laryngectomy, the dog was admitted for a solitary hepatic metastasis. While hospitalized, the dog died of apparent asphyxiation attributable to stoma collapse.

Abstract
1. The first loop of the domestic hen's magnum was fistulated. A cannula mounted with a collecting tube served to trap the passing ova about 2.5 h following ovulation. 2. Nine out of 10 fistulated hens resumed ovulation about 2 to 5 weeks following surgery. A total of 63 magnal ova were collected. 3. Five of the magnal ova were successfully returned to the oviduct through the fistula and resulted in 5 normal soft-shelled eggs. The success of ova reimplantation was affected by prolapse of the posterior part of the oviduct and the timing of ova return.
