Anatomic and ultrasonographic evaluations of tendons and digital cushions of normal phalangeal region have been assessed to be compared with abnormal digits in future studies. The reported study was carried out on 10 feet specimens of both fore and hind limbs from freshly slaughtered mature camels of both sexes and of different ages and body weights and on normal digits of three apparently normal camels. Transverse and sagittal ultrasongraphic examinations were carried out on all digits from fetlock joint to the nails using Toshiba ultrasound device connecting with 6-8 MHz linear transducer. The ten feet specimens were dissected to visualize the anatomical structures of the camel’s digit and compare them with our ultrasonographic findings. All ultrasonographic and anatomic findings of common digital extensor tendon, superficial and deep digital flexor tendons, digital cushions and sole were described. We concluded that ultrasonography is a highly impressive cross sectional diagnostic imaging tool used for evaluation of the soft tissues of the camel feet.

Information regarding the use of ultrasonography in the diagnosis of testicular and scrotal affections is scarce in bovine. In the present study, eight bulls suffering with scrotal swellings were examined ultrasonographically. The recorded affections included; ruptured urethra with scrotal swelling, testicular hypoplasia, malignant Sertoli cell neoplasm, hydrocele and scrotal hernia. In case of ruptured urethra, the scrotum appeared as thick hyperechoic skin, the testes showed normal echogenicity and the surrounding tissue showed diffuse anechoic areas separated by hyperechoic threads. The hypoplastic testis was less echogenic, and its rete testis was more echogenic, than the normal one. The neoplastic testis had several anechoic areas, hyperechoic masses and areas of normal testicular echogenicity. In hydrocele, the scrotal skin appeared as clear hyperechoic line with anechoic fluid accumulated in the vaginal cavity of the scrotum and both testes had normal echotexture. In scrotal hernia, a hyperechoic omental loop was seen adjacent to high echogenic testis. In conclusion, ultrasonography is a good tool for differential diagnosis of different scrotal swellings in bulls.

The aim of the present study is
to assess the efficacy of trans-abdominal intra-prostatic injection of ethanol and oxytetracycline Hcl under ultrasonographic guidance for treatment of canine BPH.
Under sedation with xylazine Hcl (1mg/kg i/v), aseptic precautions and ultrasonographic guidance, canine BPH was diagnosed in twelve dogs.
Ten
dogs were allocated randomly into one of the following groups: Group I, five dogs were injected trans-abdominally with ethanol (5-10 ml) after aspiration of the intra-prostatic cyst if present. Group II, five dogs were injected trans-abdominally with oxytetracycline Hcl (5-10 ml) after aspiration of the intra-prostatic cyst if present. Ultrasonographic follow up was performed in all injected dogs for two months. Repeated injections were carried out on dogs that did not respond well after one month of the first injection. Postmortem examination was carried out on two dogs which were euthanized by the request of the owners as the dogs were in severe pain due to other affections. The Results indicated that
there was obvious reduction of the prostatic size in both groups after one month of injection and disappearance of the clinical signs. Ethanol is more potent than oxytetracycline Hcl as sclerosant in canine BPH. All data about the cases, clinical signs, abdominal and rectal examinations and ultrsonographic and postmortem findings were recorded. In conclusion;
trans-abdominal intra-prostatic injection of either ethanol or oxytetracycline Hcl is an easy, quick, effective, safe, minimally invasive and cheap technique for treatment of canine BPH. Ethanol is more potent than oxytetracycline Hcl as sclerosant in canines BPH.

The aim of the present work is to study the effect of different formulations of Ca (OH)2 on healing of induced periapical lesions in dog. A total of 96 teeth with intentionally induced periapical lesions were classified according to the observation period into three groups; I, II and III (2 dogs each). Each group was subdivided into four subgroups (8 teeth each) namely; A, B, C and D which were dressed with Ca(OH)2 with saline, Ca(OH)2 with chlorohexidine, Ca(OH)2 with iodoform and control respectively. Histopathological findings showed that the apical and periapical repair were better in subgroup A than in other subgroups in all groups. Total inflammatory cell count was significantly different between the four subgroups in group I. In both groups II and III, there was no significant difference between subgroups B and C. In conclusion, the use of saline as a vehicle for Ca (OH)2 has a favorable action on periapical tissue healing in endodontically treated dogs.

There is not much data about diclofenac sodium as an anti-inflammatory drug in veterinary practice, therefore the objectives of this study were to assess the efficacy and adverse effects of diclofenac sodium on its own and together with cefotaxime Na as postoperative pain control in dogs. A prospective, randomized, blinded, clinical trial was assigned to one of four groups according to postoperative injections: Group 1 (given diclofenac and cefotaxime), group 2 (control), group 3 (given cefotaxime only) and group 4(given diclofenac only). Examinations were performed postoperatively using a pain scale modified from University of Melbourne at 0,1,2,3,4,5,6,8.12.24 h. Statistical analysis of results was done. The results of the present study showed that groups (1 and 4) had mean pain scores which were not significantly different from each other and different from groups (2 and 3) significantly. From three hours post-operative till twenty four hours post-operative groups (2 and 3) recorded mean pain scores which were significantly higher than groups (1 and 4). On the other hand, groups 2 and 3were not statistically different from each other. Also groups 1 and 4 were not statistically different. In conclusion, diclofenac sodium is an excellent analgesic for postoperative pain control in healthy dogs undergoing ovariohysterectomy

Revascularization protocol could be a promising treatment option for open apices. The aim of this study was to assess the regenerative potential of immature teeth with necrotic pulp following revascularization procedure. Three premolars in each quadrant of nine mongrel dogs of 6-9 months old were included in this study summing up the total number of 108 teeth (216 root canals). Samples were divided into three equal groups according to the evaluation period. Each group was further subdivided into 6 subgroups according to the treatment protocol including; MTA apical plug, revascularization protocol, revascularization enhanced with injectable scaffold, MTA over empty canal, positive and negative control subgroups. Periapical pathosis was induced in all experimental subgroups. Canal disinfection was then done using the triple antibiotic paste. After disinfection, treatment modalities were performed according to each subgroup. Samples were evaluated radiographically for increase in length, thickness and apical diameter. The results of this study revealed that, revascularization and revascularization enhanced with injectable scaffold were significantly higher regarding increase in length, thickness and decrease in apical diameter than other subgroups. In conclusion, revascularization procedure can be considered as a reliable treatment option for open apices in dogs.

The aim of this study was to compare the effect of different kinds of surgical meshes on postoperative adhesion formation. Twelve dogs were used in this study. The dogs were grouped into four groups, according to the type of surgical meshes (Prolene, Vicryl, Ultrapro, and control group) implanted onto the abdominal wall and intestine. Forty days after the operation, the relaparotomies were carried out, and any observed adhesions between the implanted mesh and tissues, were evaluated and graded macroscopically and microscopically. The mean adhesion degree was 8.9 in the prolene mesh group, 4.5 in the ultrapro mesh group (p>0.05), and 2.9 in the vicryl mesh group. The mean adhesion degree was 1 in the control group. There was a significant difference in the adhesion degree and inflammatory reaction between the control, prolene, vicryl and ultrapro groups. The adhesion degree was significantly lower in the vicryl and ultrapro mesh groups than the prolene mesh group.

Radiographic images of the thorax are important for evaluating patient with known or suspected thoracic diseases. Thoracic radiography provides direct information about lesions or abnormalities in lung parenchyma, airways and pleural and mediastinal spaces.
: the present study was carried out between October 2006 and June 2009. Plain thoracic radiography was done on 82 clinical cases of dogs diagnosed clinically as having respiratory disease. Contrast radiography was used where indicated.
The recoded affections were ; pectus excavatum (2 cases), Tracheal collapse (5), esophageal dilatation (9), mediastinal foreign bodies (2), pneumomediastinum (2), tension pneumothorax (12), hydropneumothorax (1), pleural effusion – mild- (4), moderate (9) and severe (15), primary lung neoplasm (3), focal metastatic pulmonary neoplasia (7), metastatic tracheobronchial lymphadenopathy (2), metastatic rib neoplasm (1) and pulmonary bullae (3).
Thoracic radiography serves to verify the diagnosis, document the extent and location of the lesion, assist in detecting complications and also help in classifying the lesions.

The records of fourteen cows with ocular squamous cell carcinomas were reviewed to determine the influence of therapy on the outcome of the case. The disease was more prevalent in Holstein cattle (8 cases), however, Friesian and native cattle were at risk (3 cases).The mean age of the affected cows was 7 years and all of the affected animals were females. The nictitating membrane, eyelids and conjunctiva were the most common sites of this neoplasm. The regression rate of the neoplasm after various surgical interventions was 57.1% while it was 85.7% after combined surgery and immunotherapy. The results of treatment concluded that addition of immunotherapy to various surgical interventions of BOSCC is a helpful method to improve the regression rate especially in neoplasms of the conjunctiva and eyelids particularly those of large sizes.

In the present study, 26 dogs with cutaneous neoplasms were examined, during a period of one year, belonging to twelve breeds. Twenty cases (77%) had single neoplasm and just 6 cases (23%) had multiple neoplasms. The neoplasms were categorized as: epithelial tumors (cutaneous papilloma, squamous cell carcinoma & sweat gland adenoma), mesenchymal tumors (lipoma, fibroma& hemangioma), lymphohistocytic tumors (histocytoma) and melanocytic tumors (melanoma) with a percent of 42%, 46%, 8% and 4% respectively. Potentially malignant neoplasms were (12%), while benign neoplasms were (88%). Head and neck were the most affected regions (50%). Surgical excision was found to be enough for treatment of most of these neoplasms. Clinical and histopathological findings were discussed.
