RESUMEN
Mammary gland tumors are very rare in male dogs. In this study, four mammary gland tumors from 3 male dogs (2 intact, 1 neutered) were collected from local animal hospitals. The dogs included two purebred Shih Tzu (1 intact, 1 neutered) and one intact purebred Cocker Spaniel. The mean age of dogs with mammary gland tumors was 9 years (5-12 years). Two dogs had a solitary mass, whereas one dog had two mammary masses. Of the four tumor masses, three were observed in the fourth or fifth mammary glands, and one was observed in the third mammary gland. According to histopathologic examinations, all four mammary masses from three dogs were benign tumors including two benign mixed tumors in one case and two complex adenomas. There were no history of obesity, testicular tumors, diabetes, and sex hormonal therapy in any male dogs with mammary tumors. Surgical excision was the only reported treatment for these tumors. No recurrence or metastasis was recorded up to 25 months after surgery.
RESUMEN
PURPOSE: To evaluate the biologic changes of xenograft (Lubboc, Transphyto S. A., Clermont-Ferrand, France) applied in the surgical treatment of calcaneal fractures. MATERIALS AND METHODS: Xenograft were used in twenty-five calcaneal fractures, as bone substitutes for mechanical support of the articular surface from March 1994 to December 1996. Twenty-four cases had obtained clinical and radiological bony union without complications. We performed biopsy at the xenograft area in eight cases when the hardware was removed. And then we took a magnetic resonance imaging of the calcaneus after the biopsy in three cases. RESULTS: The pathologic findings of the xenografts showed dead bony trabeculae with inflammed fibrous tissue. There was no osteoblastic activity but some osteoclastic activity was seen in the graft-host junctional area. MRI findings showed that there was well-circumscribed, low-signal intensity in the xenograft area contrast to the normal bony signal intensity. Its lesion was equal to the sclerotic finding in the calcaneal radiograph. CONCLUSIONS: Xenograft (LUBBOC'), which is used in the mechanical support of the articular surface, apparently lacks osteogenic capacity.

Fracuture-dislocation of the cuboid is an extremely rere injury compared with fracture-dislocation of other tarsal bones. We report a case of the fracture-dislocation of the cuboid treated by open reduction and internal fixation.

The 121 nontraumatic subarachnoid hemorrhage patients who showed mainly subarachnoid hemorrhage without considerable intracerebral hematoma on C.T. finding admitted at Kyungpook National University Hospital for recent 1 year, were evaluated the exact causes of hemorrhage with variable diagnostic methods including 4-vessels cerebral angiography. Even with full studies of repeated 4-vessels cerebral angiography, 8 patients remained idiopathic cases without the clear causes. Out of 8 patients, authors selected 3 cases who had firm history of spontaneous subarachnoid hemorrhage, revealing some evidence of aneurysmal bleeding characteristics on brain C.T. scannings and cerebral angiographic findings, and operated on them for the perfect treatment with confirming the cause of bleeding. The operation called for treatment by clipping and coating on the aneurysmal sacs found in all the 3 patients.

Cancer of the gastric stump, first described by Balfour in 1922, is defined as the cancer detected more than 5 years after surgery for a benign disease. We experienced a case of cancer found at the gastric stump after gastrojejunostomy in a 53 years old male patients, proven pathologically as a early cancer. He visited to our hospital with the chief complaint of epigastric pain and indigestion for 1 Months. On past history, he has been received gastrojejunostomy due to duodenal ulcer obstruction, 23 years ago, Gastrofiberscopy was done, and we could find the early gastric cancer lesions at the anterior wall of gastric angle as type Ilc+III and antrum as type IIa. The microscopic finding of the multiple endoscopic biopsies at the gastic angle and antrum revealed the adenocarcinoma of signet ring cell type infiltrated to the level of submucosa. And so, we could diagnose these lesions as a early gastric cancer in the gastric stump after gastrojejunostomy. He was treated with subtotal gastrectomy and discharged with cured condition. Therefore, we report this case with a literature review.

Peptic ulcer can occur anywhere in the gastrointestinal tract that contact with acid and pepsin. But usually peptic ulcer occurs at the stomach and duodenum and the location of peptic ulcer are localized to specific area within the stomach and duodenum. So I think that predilection of peptic ulcer to localized area may have clue for releaving the pathogenesis of peptic ulcer. So I studied the location of peptic ulcer for the basic reserch of ulcer pathogenesis by means of dividing stomach into antrum, angle, lower body, middle body, upper body and lesser curvature, anterior wall, greater curvature, posterior wall and duodenum into anterior wall, lesser curvature, posterior wall, and greater curvature. The results obtained were as follows: 1) The chronic gastric ulcer was most common in the angle of lesser curvature (22.9%) and second common in the antrum of lesser curvature (22.3%). 2) The location of chronic and acute gastric ulcer was similar. 3) The proximal migration of ulcer site according to increasing age was not observed. 4) Chronic duodenal ulcer was occurred commonly in the lesser curvature (41.8%) and anterior wall (38.3%). 5) As the age increase, the incidence of chronic duodenal ulcer in the lesser curvature was increased and that of chronic duodemal ulcer in the anterior wall was decreased. 6) Acute ulcer of stomach and duodenum has no predilection site.
