A 7-year old Holstein bull showing marked thickening of left forelimb was diagnosed as pulmonary hypertrophic osteoarthropathy on the histological basis of the exostotic bone of left metacarphus. Thickening of the bone was due to apposition of excessive cancerous bone beneath the periosteum on the shaft. The lung lesion of the bull, chronic suppurative bronchopneumonia was possibly related to pathogenesis of the bone thickening.

The objective of this study was to assess the teratogenic and embryotoxic effects of clomiphene citrate in mice. The pregnant mice were administered a single dose of clomiphene citrate at different concentrations i.e 1.0, 2.0, 4.0 and 6.0 ${\mu}g/g$ BW on day 8 of gestation. Fetuses recovered on day 18 of gestation were analyzed on morphological, morphometric and histological basis. Morphological observations showed defects like open eyelids, anophthalmia, fore and hindlimb micromelia, meromelia, amelia, sacral hygroma, hydrocephaly, hemorrhagic spots, kyphosis and clubbed feet. Morphometric analysis indicated a significant (p<0.001) reduction in fetal body weight, crown rump length, head circumference, eye circumference, forelimb and hindlimb lengths and tail size against controls. The histological observations showed brain defects like hydrocephaly, enlarged ventricles and undifferentiated neuroglial cells in cerebellum. Cleft palate, underdeveloped pharynx and atrophy of jaw muscles were the common anatomical defects of pharyngeal region. It is concluded that the concentrations of clomiphene citrate used during the present study proved teratogenic in mice fetuses.

This study was carried out to investigate the characteristics of 335 injured racehorses that had rested over 6 months or were retired in Seoul racecourse from 1994 to 1998. We surveyed 62,117 racing horses and incidence rate of injured horses was 0.54%. Of 335 horses, 322 horses(96.1 %) were associated with musculoskeletal disorders. The musculoskeletal disorders observed with high incidence were fracture and luxation(53.1%), tendinitis and desmitis(17.7%) in category, forelimb(92.5%) in location, below metacarpus/metatarsus(73.0%) in lesion. The prevalence rate of male, 5 years old or Ireland origin was higher than any other individual. These data would be useful standard reference for control of injuries in racing horses.

Specific diagnosis of orthopedic disease can be diffcult in canine practice. Failure to detect the clinical signs of a disorder during physical examination of dogs with acute or chronic lameness is the most common reason for failure to make specific diagnosis. A 6-month-old, female doberman with history of swelling and non-weight-bearing lameness in the left forelimb was referred to Beterinary Teaching Hospital of Chungbuk National University. Physical examination, plain radiography, and conventional three-phase radionuclide bone scan were performed in the patient. Based on the physical exam and radiography, this case was diagnosed as elbow strain and subluxation. Conventional three-phase bone scan detected soft tissue inflammation and osteochondral lesions of elbow joint, and revealed good agreement with clinical findings. Therefore, conventional three-phase bone scan was able to provide the precise information about inflammation of soft tissue and osteochondral lesions of joint.

Three dimensional computed tomographic images were obtained in two cases with trauma. The first case of a 3 year-old male Maltese, with ataxia and head tilting due to head trauma was referred to veterinary medical teaching hospital, Seoul National University. Remarkable findings were not found on survey radiographs. With the help of three-dimensional reconstruction computed tomographic imaging, parietal and occipital bone fracture was identified. The second case of 4 month-old female Yorkshire terrier with left forelimb lameness was referred right after trauma. Survey radiography showed obvious incongruity of the elbow joint. Lateral and medial condyle of the left humerus fracture and lateral displacement of the left ulna were apparent in three-dimensional computed tomographic image. It was considered that three-dimensional computed tomography could be used as an aid modality for the exact evaluation of extends and degree of fracture as well as planning of orthopedic surgery.

A 3-year-old male Thoroughbred serving as a Korean racehorse named RAON PORTEOUS presented with acute lameness concomitant with edema and fever in the right carpal joint after completing a horse race. Through radiological examination using lateromedial oblique, flexed lateromedial oblique and dorsopromixal-dorsodistal oblique views, the horse was diagnosed with a slab fracture in the 3^rd carpal bone of right forelimb. The fracture was surgically approached and corrected by applying 4.5 mm leg screw fixation during surgery. At eight months post-surgery, the horse was able to return to racing and has had successful racing performances with two wins and several prizes in the last 8 months. This is the first reported case of the successful use of lag screw fixation surgery in Korea with the horse showing complete recovery from a severe injury that is often considered fatal in a racehorse.
