This study designed a protocol that would combine pregnant mare serum gonadotrophin (PMSG) and cabergoline (CAB) to induce estrus in bitches. Twenty clinically healthy adult and anestrous female dogs were randomly assigned into four groups. The first group was treated with 5.00 μg kg-1 CAB until the onset of proestrus or for 25 days. The second group was treated with 20.00 IU kg-1 PMSG for 5 days and 500 IU human chorionic gonadotropin (hCG) on the 5th day. The third group was treated with 5.00 μg kg-1 CAB for 10 days in combination with 20.00 IU kg-1 PMSG for 5 days and 500 IU hCG on the 10th day. The control group received 1.00 mL of normal saline. Ovarian changes were evaluated ultrasonographically, and the estrus cycle phase was examined by vaginal cytology. Respectively, three, three and four bitches showed clinical signs of proestrus in each treatment group. The intervals between treatment and proestrus for each group were 30.00 ± 3.05, 7.67 ± 1.20 and 13.00 ± 1.20 days, respectively. Two weeks after estrus, the progesterone mean was 14.51 ± 6.24, 19.96 ± 17.16 and 19.12 ± 9.26 ng mL-1 for each group, respectively. In ultrasonography examination, the largest follicle was identified at 15.66 ± 1.33, 11.66 ± 2.40 and 8.75 ± 2.17 days after the onset of proestrus and the largest follicle’s size was measured 6.50 ± 0.55, 4.83 ± 1.64 and 7.07 ± 1.49 mm for each group, respectively. Although the combined use of CAB and PMSG reduced the duration of treatment, alteration of the duration or PMSG dosage can be helpful to improve the results.

Superficial digital flexor tendon (SDFT) plays an important role in the locomotion of the horses with flexion of the limbs. In the hind limb, it passes over the calcaneal bone and attaches to medial and lateral surfaces of calcaneous by two bands of connective tissue; while, the medial band is weaker than the lateral one. Occasionally, severe trauma, over-extension or fracture of the calcaneous may cause rupture of the supportive bands leading to tendon luxation. An 11-year-old Thoroughbred jumping gelding with symptoms of lameness in both legs, after examination by an internal specialist veterinarian in equine practice field was referred to the Teaching and Research Hospital of the Faculty of Veterinary Medicine of the University of Tehran, Tehran, Iran. Clinical examination showed lateral luxation of SDFT in the right and left tarsal joints. Radiography revealed no sign of calcaneal involvement, except soft tissue swelling. In the radiography of the tarsal joints, the calcaneus bones did not show significant changes, but among the bones of the central and 3rd tarsal bone (distal intertarsal joint) of the tarsus, osteophyte formation was observed to a mild extent, indicating mild bone spavin in both tarsal joints. In ultrasonography, SDFT thickenings accompanied by hypoechoic regions in tendons were seen, confirming the signs of tendonitis. Moreover, fibrous tissue formation was diagnosed. In the left leg, anechoic fluid in the calcaneous bursa was seen. Evaluation of diagnostic imaging findings enables veterinarians to diagnose the site and extent of the lesions, choosing the appropriate therapeutic approach in addition to clinical symptoms.

The aim of this study was to investigate the relationship between mastitis and supra-mammary lymph nodes in lactating cows in terms of Pulsed-wave (PW) Doppler ultrasonographical measurements. A total of 102 head cows in lactation period were divided into three groups. The cows in which all mammary lobes were California mastitis test (CMT)-negative (n = 27) formed the 1st group; those with CMT-positive mammary lobe (n = 43) formed the 2nd group and the cows with clinical mastitis in at least one mammary lobe (n = 32) formed the 3rd group. In PW Doppler ultrasonography, end-diastolic velocity, systolic peak velocity and time-averaged maximum velocity were measured at the most prominent artery of the lymph node. A quantitative scaling was performed by determining the pulsatile index and resistance index scales based on blood flow parameters. There was no statistically significant difference between the study groups in terms of PW Doppler ultrasonographical measurements of supra-mammary lymph nodes. In conclusion, the use of PW Doppler ultrasonographic data of the supra-mammary lymph nodes will not provide useful information about the current condition of mastitis in cows.

Ceruminous gland tumor is the most common tumor of the ear canal in cats. Otoscopic examination of the ear tumor is so difficult due to narrowing of the external ear canal. The present study aimed to investigate clinical, ultrasonographic and histopathological characteristics of feline ceruminous gland neoplasm in cats. Ten cats with unilateral ear canal swelling were subjected to thorough physical and clinical investigations. Ultrasound of the ear canal and parotid gland was performed using 8.00 MHz linear probe. Tissue specimens were collected after surgical excision (total ear canal ablation) for histopathological examination. Clinical examination of the ceruminous tumors revealed firm pinkish mass obliterated the ear canal with purulent or bloody aural discharge. Ultrasound examination of the ear tumor was helpful in detecting the size, shape, echogenicity and extension of the tumors to the surrounding structures as well as the nature of the feline ceruminous tumor. Histopathological examination was the main diagnostic tool for detecting the nature of the ceruminous neoplasms.

Ultrasonography is an accurate and accessible method for detecting polycystic kidney disease (PKD), an inherited autosomal dominant disease, and other urinary tract diseases. The present work is a preliminary study of PKD and urinary tract abnormalities using ultrasonography in Persian and other long hair cats in Iran. This study was conducted on 83 cats including 68 Persian cats and 15 Persian related cats from December 2013 to March 2015. The age of cats ranged 3 to 72 months. Cats were classified as PKD-positive when at least one renal cyst was observed. Other urinary system abnormalities were recorded ultrasono-graphically. Association of personal and nutritional characteristics with PKD and other urinary tract disease detected by ultrasonography was statistically analyzed. The prevalence of PKD among Persian cats and in the total population was 33.80% and 31.30%, respectively. PKD was more prevalent among male cats compared to those in female cats. PKD occurrence was significantly more among cats fed by commercial dry foods compared to those fed by homemade foods. There was no significant association between PKD and age, hair color, eye color, related clinical signs and other kidney abnormalities in ultrasonographic findings. The prevalence of renal calculi, urine sediments and bladder calculus were 2.40%, 32.80% and 3.60%, respectively. Urine sediments were significantly raised with increasing age. Screening program is essential for on-time diagnosis of PKD and to plan therapeutic management and control of the disease.

Bilateral simple ectopic kidney was diagnosed in an apparently healthy 3-year-old, female domestic short hair cat, incidentally based on radiology and ultrasonography examination. The cat was presented for routine examination without any complaint. In clinical evaluation, no significant abnormal clinical sign was seen except for the absence of both kidneys in their proper location in abdominal palpation, which they were palpated more caudally. Radiography revealed silhouettes of soft tissue opacity in the caudal part of the abdominal cavity superimposed on urinary bladder. Ultrasonography confirmed the presence of both kidneys more caudally. The left kidney was dorsal to the urinary bladder and the right kidney located cranially than the left one. Each kidney showed normal shape and size and imaged in their proper side. Hematological, biochemical and urinalysis examinations showed normal values. Ectopic kidney can be diagnosed in feline patients as an incidental finding but it is important to evaluate the kidney for concurrent problems.

Ultrasonographic examination of urinary system (kidney and urinary bladder) was conducted in New Zealand white rabbit [NZwr] and Tolai hare (Lepus tolai). Ultrasound images of the kidney and urinary bladder were evaluated on fifteen healthy rabbits of New Zealand white rabbit and another fifteen Tolai hares. The healthy rabbits were 8-12 months old (mean = 9.3 months), of both sexes and weighed between 1.1-1.7 kg (mean = 1.250 kg). All examinations were performed while the rabbits were in dorsal recumbancy. The kidneys were examined from fossa by the use of an 8 MHz linear real-time scanner. This study revealed the following measurements normal rabbit kidneys: 27.80-35.70 mm and 16.90-22.40 mm in length and width in New Zealand white rabbit, respectively. The length and width were 26.67-34.50 and 15.82-20.60 mm, in Tolai hare, respectively. Bladder wall thickness varies from 1.70-2.50 mm (in New Zealand white rabbit) to 1.80-2.60 mm (in Tolai hare). Statistical analysis showed that the gender did not have effect on length, width and weight (P > 0.05), but the type of the animal, had significant effect on the cortex and surface (P < 0.05). In the present study, the renal cortex was uniform in echogenicity, hyperechoic to the renal medulla, hypoechoic to the spleen, and isoechoic to the hepatic parenchyma.
