We have experienced a rare case of traumatic ventricular septal defect caused by fall down injury. The patient suffered from congestive heart failure after trauma and represented new developing typical murmur. Cardiac catheterization revealed a large left-to-right shunt at the ventricular level and a 4.4:1 ratio of pulmonary to systemic flow. Left ventricular angiogram also showed ventricular septal defect low in the muscular septum. At operation, the right ventricle and pulmonary artery were found to be moderately dilated. A marked systolic thrill was palpable over the right ventricle near the apex. Through a small left ventriculotomy an oval defect, 2x.3 cm with a firm scarred margin, was found in the lower muscular ventricular septum. This defect was repaired using Dacron patch and ventriculotomy was closed with long strip of Teflon felt. Postoperative course was uneventful and discharged in good condition.

A-13-urar-old with a history of Alport syndrome had been suffering from progressive dysphagia and postprandial vomiting for over 7 years. Exophagogram and manoemtric studies were consistent with achalasia. Barum study demonstrated marked esophageal dilatation and smooth tapered narrowing of the distal esophagus. However in spite of the medical treatment including the injection of the distal esophagus. However in spite of the medical treatment including the injection of botulinum toxin at the lesion site using an endoscope symptom did not improved and he suffered growth failure and malnutrition. Esophagectomy and esophagogastrostomy were performed to relieve the dysphagia. A firm circumferential intramural mass about 7$\times$5$\times$5 cm was found in the distal esophagus. The lumen of the esophagus was markedly dilated and esophageal wall was hypertrophied. Histologic examination of the neoplasm revealed a rather ill defined tumor tissue consisting of interlacing or whirling spindle cells without significant mitosis and esophageal leiomyo-matosis was confirmed. The patient was discharged uneventfully.

We report a spontaneous embryonal rhabdomyosarcoma in the abdominal cavity of an aged (88-week-old) Sprague-Dawley rat. The animal had a firm lobulated $5{\times}5{\times}4.5cm$ mass in the abdominal cavity that was whitish to tan with necrotic and hemorrhagic plaques. Microscopically, the mass contained nodules with spindle or globoid shaped neoplastic cells with abundant eosinophilic cytoplasm and round or elongated nuclei mixed with other spindle cells with a filamentous appearance and scanty cytoplasm. Multinucleated cells and cross-striations were also observed. The neoplastic cells were positive for vimentin, desmin, and alpha-smooth muscle actin, especially the small spindle cells.

A 14-year-old female Gill's bottle-nosed dolphin died after having 1 month history of depression, anorexia, and respiratory insufficiency. At necropsy, numerous well-demarcated tan firm nodules in variable sizes ranging from 2 m to 3 cm in diameter were scattered throughout the lung lobes. Histologically, the pulmonary nodules formed typical granulomatous inflammation. Center of the granulomatous foci consisted of necrotic center with gram positive cocci surrounded by eosinophilic Splendore-Hoeppli material then by macrophages, epithelioid cells, multinucleated giant cells, a few lymphocytes and fibroblasts. The is the first report of pulmonary botryomycosis in dolphin in Korea.

An 11-year-old, toy poodle dog was presented with dermatologic lesions and mammary gland tumor (MGT) evaluation. A solitary, lobulated MGT (size $2.5{\times}3.5$ cm) was affecting the 5th left mammary gland. Firm, oval plaque skin lesions were present on the left dorsal carpal area. The skin lesions were alopecic and salivary staining. The dog had historical separation anxiety and excessive licking of skin lesions were observed. Based on the clinical and histopathologic examinations, MGT was diagnosed with mammary complex adenoma and the skin lesions were diagnosed with acral lick dermatitis. Behavior modification treatment using oral clomipramine was effective.

At the time of visiting, the cat was 6-year-old female Siamese cat. The mammary mass was solid and firm and measured $2{\times}5cm^2$ in greatest diameter. The uterus revealed thick uterine horn and cross sectioned wall. Histopathologically, the mammary mass revealed feline mammary carcinoma. In the uterus, cystic endometrial hyperplasia was observed. Feline leukemia virus positive reaction was detected by polymerase chain reaction. As far as we know, this is the first report of the simultaneous feline mammary carcinoma and uterine endometrial cystic hyperplasia with Feline leukemia virus infection in a cat.

A primary metastatic malignant plasma cell tumor was presented in a 7-year-old, female, mixed breed dog. The dog was admitted to Veterinary Teaching Hospital at College of Veterinary Medicine, Seoul National University after suffering from depression, anorexia, and dyspnea. The dog was euthanized due to poor prognosis. At necropsy, numerous, firm and tan round nodules, 1 to 2 cm in diameter were noted in the ribs. The nodules formed chain or were occasionally coalescing, causing osteolysis of the ribs. A large amount of clear fluid was present in the thoracic cavity. The spleen and liver were markedly enlarged and congested. Histologically, the nodular masses were diagnosed as plasma cell tumor which was believed to be originated from the rib. Evidence of metastasis was observed in the spleen, liver, and kidney.

The present study has an objetive to define the characteristic of the Porous Concrete to be used in the resistant layers of the pavement. Up to the moment there is no material which is capable which is capable of satisfying the mechanical resistances and drainability, two characterstics which interves, and a detailled study has been carried out on the same order to obtain the porous concrete of this study. such as: Mode and time of compaction. type of cement, water/cement ratio, maxium size of aggregates, sieve test. incorporation of some additives and additions etc., among them emphasizing the use of a method of compaction vibro-compression in the laboratory with which an optimum compacting was reached, and can be obtanied on the site with a spreader rated with double tamper. With this porous concrete for this study whose dominating characteristics is the drainability jointly with a high mechanical resistance. a safe and silence firm is obtained, with can be a great diffusion in the near future, for its application on the pavements. Based on these works carried out, there was the first experience in the world of field application with 25cm of resistance layer of Porous Concrete Pavement in Salamanca, Spain.

Pilomatricoma, calcifying epithelioma of Malherbe, is a benign skin neoplasm of hair matrix origin that is typically occurred in the head and neck region. It usually presents as a superficial, firm, solitary, slow-growing, and painless mass of less than 3 cm in diameter and most often occurs in young age under 20 years. The tumor does not express an aggressive behavior and surgical excision is the treatment of choice. The purpose of this article is to present a case of pilomatricoma of the preauricular region and to review the literature regarding pilomatricomas of the head and neck region.

This study comprised 13 cases having canine perianal adenoma at Veterinary Medical T~aching Hospital, Seoul National University from January 2000 to October 2003. All referred dogs were intact male and mean age of dogs was 11.5 years (ranged from 7 to 15 years). The most prevalent breed was Shih Tzu. The clinical signs were presence of 1 to 5 cm in diameter firm mass, perianal swelling, hemorrhage, pain and dyschezia. The masses were located either in the perineum (12 cases) or tail (5 cases). Five dogs had masses with ulceration. Concurrent prostatomegaly and seminoma was found in 5 and 1, respectively. Castration was performed in 5 cases. In 8 cases, surgical excision of the tumor was performed with castration. There was no recurrence in all cases after removal. In all cases with castration, perianal adenomas were regressed within 1-2 months. In one case among them, excision of the tumor was also performed because of persistent ulceration. According to these clinical results, perianal adenoma excellently responded to castration with or without surgical excision of the tumor.
