A 7-year-old, spayed female Chihuahua with dyspnea, intermittent cyanosis, and dermal plaques was diagnosed with hyperadrenocorticism. Thoracic radiographs showed markedly hyperdense alveoli in multiple lung lobes. Computed tomography (CT) images showed lung mineralization confined to the lung parenchyma and pituitary macroadenoma. Pulmonary mineralization secondary to hyperadrenocorticism is commonly found on histopathologic examination. However, those lesions are rarely identified radiographically. We describe obvious pulmonary mineralization secondary to hyperadrenocorticism found on radiographs and present the first report regarding CT imaging of the mineralization. Pulmonary mineralization should be considered when a dog affected by hyperadrenocorticism shows diffuse lung mineralization on radiographs.

The pathogenesis of pancreatic pseudocyst is still not understood. A 5-year-old, 24-kg intact female Shetland Sheepdog was presented with anorexia and vomiting. Diagnostic imaging tests revealed that the left limb of the pancreas was thickened and contained two cystic lesions ($6.3{\times}5.6{\times}4cm^3$ and $3.5{\times}4.6{\times}5.5cm^3$). During the laparotomy, lesions were opened with de-roofing of superabundant tissue, and omentalization was performed. The dog recovered uneventfully after surgery and was discharged on postoperative day 12. Histopathologically, it was diagnosed as chronic pancreatic pseudocyst. This case report describes the diagnosis and successful omentalization of pancreatic pseudocysts in a dog.

In sewing, fabrics is fed by an elliptic motion of the feed dog. The feeding control mechanism controls an elliptic motion of the feed dog, finally, controls stitch spacings and feeding directions of fabrics. This study discusses the feeding control mechanism of an industrial lock stitch sewing machine, which is a good example to study a machine kinematics. This study makes mathematical expressions of machine's motion in the feeding control mechanism. Thus, the motions of this mechanism are characterized, which will be used for kinematic analysis of the feed dog later. Also, the above mathematical expressions may be a basis for the new design of the feeding control mechanism and may be applied to development of the similar feeding control mechanism of other type sewing machine.

A primary sternal chondrosarcoma was diagnosed in a 16-year-old, male mixed breed dog. The dog was admitted to Veterinary Teaching Hospital at College of Veterinary Medicine, Seoul National University after suffering from depression, anorexia, dyspnea, panting and expiratory honking sound for 2 months.

The raccoon dog (Nyctereutes procyonoides) may be infected by Dirofilaria immitis. However, there has been no report on dirofilarial infection in the raccoon dog in Korea. In this study, we report on D. immitis infection in two wild raccoon dogs captured in the Daejeon area. The two raccoon dogs were referred to the Veterinary Teaching Hospital, Chungnam National University for diagnosis of D. immitis infection. The modified Knott's test for the detection of blood D. immitis microfilariae was positive, and serological test (FASTest$^{(R)}$ HW Antigen ELISA kit, Diagnostik Mega Cor, Austria) for D. immitis was positive as well. Additionally, D. immitis microfilariae were differentiated from other microfilariae by using acid phrnphatase histochemical staining (Leucognost-SP$^{(R)}$kit, Diagncstica MERCK, Germany). The two raccoon dogs were necropsed and D. immitis infection was confirmed.

A miniature schnauzer (8 years old, male castrated), diagnosed as diabetes mellitus 6 months ahead, were referred to the Veterinary Medical Teaching Hospital of our University with hindlimb stiffness, facial rubbing and tetany. Serum chemistry showed severe hypocalcemia, hypomagnesemia, and measured iPTH (intact pharathyroid hormone) concentration was low (< 3.0 pmol/L). Consistent rate injection of calcium gluconate (282 mg/kg over 30 min) resulted in prompt relief of the tetany. Then typical treatment for hypoparathyroidism (calcium gluconate and dihydrotachysterol per os) with magnesium administration could control the neuromuscular signs. Diabetes mellitus is being controlled by insulin therapy and prescription diet. Hypomagnesemia in diabetic dog may be induced hypoparathyrodism.

Rhabdoid tumor is an aggressive neoplasm of animals and human. It is similar with rhabdomyosarcoma histopathologically. But cellular origin of this neoplasm showed no striated muscle origin by immunohistological and ultrastructural studies. Castrated male Shit-tzu dog, 6 years old, had a mass in the left gluteal region near to the tail. The mass was examined histopathologically and immunohistologically. Histopathologically, the tumor was consisted of large polygonal cell with abundant eosinophilic cytoplasm. The nuclei in some cells were marked eccentrically located. Immunohistochemically, many neoplastic cells were positive for vimentin. These findings were similar to histopathological and immunohistological features of human rhabdoid tumor and few rhabdoid tumors in animals.

This study was performed to observe the gross reactions of surrounding maxillary sutures to the widening of midpalatal suture in the dog. Three healthy dog were chosen for the experiment. One animal was used as control, and two were used as experimental animals. Midpalatal suture was expanded total 7mm with screw for 10 days. The following results were obtained : 1. Midpalatal suture was expanded with the most width, in which anterior was be more expanded than the posterior, and shape was wedge form. 2. Interincisive suture was definitely expanded. 3. Internasal suture and interfrontal suture were slightly expanded. 4. Expansion of frontomaxillary suture, frontoparietal suture, frontonasal suture, zygomatico temporal suture, zygomatico frontal suture, zygomatico maxillary suture, occipito mastoid suture, occipito parietal suture, naso incisive suture, naso maxillary suture, and incisive maxillary suture were not observed.

Capillaria hepatica a primary trichuroid nematode parasite in rodents, has been reported in wide range of secondary hosts including humans. We report a rare case of Capillariasis in a 4-year old raccoon dog(Nyctereutes procyonoides) submitted to the Veterinary Diagnostic Laboratory Chonbuk National University for necropsy on July 5, 1996. Grossly the thoracic cavity contained approximately 200 mls of blood-tinged exudate. Edematous lesion was present around aorta and vena cava. liver was slightly swollen and mottled and contained multifocal yellowish-white lesions ranging from 1 to 3 mm in diameter. Histologically liver lesions were localized around central veins and were characterized by cell swelling and necrosis with mixed inflammatory cells surrounding parasite eggs. These eggs were barrel-shaped with polar caps consistent with Capillaria hepatica.

A six-month-old, male mongrel dog presented with wet ventral abdominal skin hairs and a short prepuce with penis. In physical examination, the penis was underdeveloped with fusion failure of the prepuce and the urethral opening was in the transitional area between os penis and perineal region. The radiological shape of urinary bladder was normal in positive contrast cystography and there was no any other routes except the observed urethral opening. Cryptochidism was also shown. It was diagnosed as hypospadia. Treatment included castration and resection of remnants of the prepuce and penis.
